                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2023), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

services or vessels to which the text pertains, and in many cases limits 
the application of the text to vessels contracted for before or after a 
specific date. As used in this subchapter, the term ``vessels contracted 
for'' includes not only the contracting for the construction of a 
vessel, but also the contracting for a material alteration to a vessel, 
the contracting for the conversion of a vessel to a cargo or 
miscellaneous vessel, and the changing of service or route of a vessel 
if such change increases or modifies the general requirements for the 
vessel or increases the hazards to which it might be subjected.

    (i) From a country to which the International Convention for Safety 
of Life at Sea, 1974, (SOLAS 74) applies, to a port outside that country 
or the reverse;
    (ii) From any territory, including the Commonwealth of Puerto Rico, 
all possessions of the United States and all lands held by the United

are the responsibility of a contracting SOLAS 74 government, or which is 
administered by the United Nations, to a port outside the territory or 
the reverse; or
    (iii) Between the contiguous states of the United States and the 
states of Hawaii or Alaska or between the states of Hawaii and Alaska.
    (b) The regulations that apply to a vessel on an ``international 
voyage'' in this subchapter do not apply to ships engaged on a voyage 
solely on the Great Lakes and the St. Lawrence River as far east as a 
straight line drawn from Cap de Rosiers to West Point, Anticosti Island, 
the 63d Meridian;
    (c) The Commandant or his authorized representative may exempt any 
vessel on an international voyage from the requirements of this 
subchapter if the vessel--

Sec. 90.05-20  Applicability to offshore supply vessels.

    (a) Existing offshore supply vessels as defined by Sec. 90.10-
40(b), if they are of 100 GRT (100 GT ITC if GRT is not assigned) as 
defined in Sec. 125.160 of this chapter or more, are subject to

Sec. 90.05-25  Seagoing barge.

    (a) Each seagoing barge, as defined in 46 CFR 90.10-36, is subject 
to inspection and certification; except that a seagoing barge is exempt 
from those requirements if it is unmanned for the purposes of operating 
or navigating the barge, and carries neither a hazardous material as 
cargo nor a flammable or combustible liquid, including oil, in bulk 
quantities of 250 barrels or more.
    (b) In applying the laws and regulations to manned seagoing barges, 
one criterion for invocation of safety standards is the description of 
seagoing barges by relative size in gross tons. When it is determined by 
the Commandant that the gross register tonnage for a particular manned 
seagoing barge, which is attained by exemptions, reductions, or other 
devices in the basic gross tonnage formulation, will circumvent or be 
incompatible with the application of specific safety requirements in the 
regulations in this subchapter for a manned seagoing barge of such 
physical size, the Commandant shall prescribe the regulations to be made 
applicable to such seagoing barge. When the Commandant

[[Page 8]]

determines that the gross register tonnage is not a valid criterion for 
the invocation of safety requirements based on relative size, the 
parties involved will be informed of the determination and of the 
regulations applicable to such manner seagoing barges, and before being 
permitted to operate such seagoing barges, compliance therewith shall be 
required. Endorsements or notations on the seagoing barge's certificate 
of inspection may be made as appropriate.

              Subpart 91.27_Annual and Periodic Inspections



Sec. 91.27-1  Annual and periodic inspections.

    (a) Annual inspection. Your vessel must undergo an annual inspection 
within the 3 months before or after each anniversary date, except as 
required in paragraph (b) of this section.
    (1) You must contact the cognizant Officer in Charge, Marine 
Inspection to schedule an inspection at a time and place which he or she 
approves. No written application is required.
    (2) The scope of the annual inspection is the same as the inspection 
for certification as specified in Sec. 91.25-10 but in less detail 
unless the cognizant marine inspector finds deficiencies or determines 
that a major change has occurred since the last inspection. If 
deficiencies are found or a major change to the vessel has occurred, the 
marine inspector will conduct an inspection more detailed in scope to 
ensure that the vessel is in satisfactory condition and fit for the 
service for which it is intended. If your vessel passes the annual 
inspection, the marine inspector will endorse your current Certificate 
of Inspection.
    (3) If the annual inspection reveals deficiencies in your vessel's 
maintenance, you must make any or all repairs or improvements within the 
time period specified by the Officer in Charge, Marine Inspection.
    (4) Nothing in this subpart limits the marine inspector from 
conducting such tests or inspections he or she deems necessary to be 
assured of the vessel's seaworthiness.
    (b) Periodic inspection. Your vessel must undergo a periodic 
inspection within 3 months before or after the second or third 
anniversary of the date of your vessel's Certificate of Inspection. This 
periodic inspection will take the place of an annual inspection.
    (1) You must contact the cognizant Officer in Charge, Marine 
Inspection to schedule an inspection at a time and place which he or she 
approves. No written application is required.
    (2) The scope of the periodic inspection is the same as that for the 
inspection for certification, as specified in Sec. 91.25-10. The 
Officer in Charge, Marine Inspection will insure that the vessel is in 
satisfactory condition and fit for the service for which it is intended. 
If your vessel passes the periodic inspection, the marine inspector will 
endorse your current Certificate of Inspection.
    (3) If the periodic inspection reveals deficiencies in your vessel's 
maintenance, you must make any or all repairs or improvements within the 
time period specified by the Officer in Charge, Marine Inspection.
    (4) Nothing in this subpart limits the marine inspector from 
conducting such tests or inspections he or she deems

[[Page 21]]

necessary to be assured of the vessel's seaworthiness.

Officer, U.S. Coast Guard Marine Safety Center, 1900 Half Street, SW., 
Suite 1000, Room 525, Washington, DC 20024, or transmitted by mail to: 
Commanding Officer, U.S. Coast Guard Marine Safety Center, 2100 2nd St., 
SW., Stop 7102, Washington, DC 20593-7102, in a written or electronic 
format. Information for submitting the VSP electronically can be found 
at http://www.uscg.mil/HQ/MSC. In this case, the plans will be returned 
directly to the submitter, with a copy of the action being forwarded to 
the interested Officer in Charge, Marine Inspection.
    (4) In the case of classed vessels, upon specific request by the 
submitter, the American Bureau of Shipping will arrange to forward the 
necessary plans to the Coast Guard indicating its action thereon. In 
this case, the plans will be returned as noted in paragraph (a)(2) of 
this section.

Sec. 92.25-5  Where rails required.

    (a) All vessels shall have efficient guard rails or bulwarks on 
decks and bridges. The height of rails or bulwarks shall be at least 
39\1/2\ inches from the deck except that where this height would 
interfere with the normal operation of the vessel, a lesser height may 
be approved by the Commandant. At exposed peripheries of the freeboard 
and superstructure decks, the rails shall be in at least three courses, 
including the top. The opening below the lowest course shall not be more 
than 9 inches. The courses shall not be more than 15 inches apart. In

----------------------------------------------------------------------------------------------------------------
\1\ On vessels of 65 feet (19.8 meters) in length or less, \3/4\-inch hose of a good commercial grade together
  with a commercial garden hose nozzle may be used. The pump may be hand operated and the length of hose must be
  sufficient to assure coverage of all parts of the vessel.
\2\ A 1\1/2\ inch hose that is 75 feet (22.86 meters) in length with a \5/8\-inch nozzle may be used where
  specified by Sec. 95.10-10(b) of this subpart for interior locations and 50 feet (15.24 meters) of 1\1/2\
  inch hose may be used in exterior locations on vessels in other than ocean or coastwise service. For vessels
  on ocean or coastwise service, two 1\1/2\ inch outlets, each provided with one 1\1/2\ inch hose supplied
  through a wye connection may be substituted.

    (b) On vessels of 1,000 gross tons or more on an international 
voyage, each required fire pump, while delivering water thru the fire 
main system at a pressure corresponding to that required by paragraph 
(c) of this section, must have a minimum capacity of at least two-thirds 
of that required for an independent bilge pump. However, in no case may 
the capacity of each fire pump be less than that otherwise required by 
this section.
    (c) Each pump must be capable of delivering water simultaneously 
from the two highest outlets at a Pitot tube pressure of approximately 
50 p.s.i. Where 1\1/2\-inch hose is permitted in lieu of 2\1/2\-inch 
hose by footnote 2 of Table 95.10-5(a), the pump capacity must be 
determined on the same basis as if 2\1/2\-inch hose had been permitted. 
Where \3/4\-inch hose is permitted by Table 95.10-5(a), the Pitot tube 
pressure need be only 35 p.s.i.
    (d) Fire pumps must be fitted on the discharge side with relief 
valves set to relieve at 25 p.s.i. in excess of the pressure necessary 
to maintain the requirements of paragraph (c) of this section or 125 
p.s.i., whichever is greater. Relief valves may be omitted if the pumps, 
operating under shut-off conditions, are not capable of developing a 
pressure exceeding this amount.
    (e) Fire pumps must be fitted with a pressure gage on the discharge 
side of the pumps.
    (f) Fire pumps may be used for other purposes provided at least one 
of the required pumps is kept available for use on the fire system at 
all times. In no case shall a pump having connection to an oil line be 
used as a fire pump. Branch lines connected to the fire main for 
purposes other than fire and deck wash shall be so arranged that 
adequate water can be made continuously available for firefighting 
purposes.
    (g) The total area of the pipes leading from a pump must not be less 
than the discharge area of the pump.
    (h) On vessels with oil fired boilers, either main or auxiliary, or 
with internal combustion propulsion machinery, where two fire pumps are 
required, they shall be located in separate spaces, and the arrangement 
of pumps, sea connections, and sources of power shall be such as to 
insure that a fire in any one space will not put all of the fire pumps 
out of operation. However, when it is shown to the satisfaction of the 
Commandant that it is unreasonable or impracticable to meet this 
requirement due to the size or arrangement of the vessel, or for other 
reasons, the installation of a total flooding fixed fire extinguishing 
or clean agent system may be accepted as an alternate method of 
extinguishing any fire that could affect the powering and operation of 
at least one of the required fire pumps.

Sec. 95.10-10  Fire hydrants and hose.

    (a) The size of fire hydrants, hose, and nozzles and the length of 
hose required must be as noted in Table 95.10-5(a).
    (b) Instead of the 2\1/2\-in hose and hydrants specified in Table 
95.10-5(a) of this subpart, on vessels of more than 1,500 gross tons:

[[Page 46]]

    (1) The hydrants in interior locations may have wye connections for 
1\1/2\-in hoses. In these cases, the hose must be 75 ft in length, and 
only one hose is required at each fire station; however, if all such 
stations can be satisfactorily served with 50-ft lengths, a 50-ft hose 
may be used; and
    (2) The hydrants for exterior locations may substitute two 1\1/2\ in 
outlets, each with a 1\1/2\-in hose, supplied through a wye connection.
    (c) On vessels of 500 gross tons or more there must be at least one 
shore connection to the fire main available to each side of the vessel 
in an accessible location. Suitable cut-out valves and check valves must 
be provided. Suitable adapters also must be provided for furnishing the 
vessel's shore connections with couplings mating those on the shore fire 
lines. Vessels of 500 gross tons or more on an international voyage, 
must be provided with at least one international shore connection 
complying with ASTM F 1121 (incorporated by reference, see Sec. 95.01-
2). Facilities must be available enabling an international connection to 
be used on either side of the vessel.
    (d) Fire hydrants must be of sufficient number and so located that 
any part of the vessel, other than main machinery spaces, accessible to 
persons on board while the vessel is being navigated and all cargo holds 
may be reached with at least 2 streams of water from separate outlets, 
at least one of which must be from a single length of hose. In main 
machinery spaces, all portions of such spaces must be capable of being 
reached by at least 2 streams of water, each of which must be from a 
single length of hose from separate outlets; however, this requirement 
need not apply to shaft alleys containing no assigned space for the 
stowage of combustibles. Fire hydrants must be numbered as required by 
Sec. 97.37-15 of this subchapter.
    (e) All parts of the fire main located on exposed decks must either 
be protected against freezing or be fitted with cut-out valves and drain 
valves so that the entire exposed parts of such piping may be shut off 
and drained in freezing weather. Except when closed to prevent freezing, 
such valves must be sealed open.
    (f) The outlet at the fire hydrant must be limited to any position 
from the horizontal to the vertical pointing downward, so that the hose 
will lead horizontally or downward to minimize the possibility of 
kinking.
    (g) Each fire hydrant must have at least one length of firehose, a 
spanner wrench, and a hose rack or other device for stowing the hose.
    (h) Firehose must be connected to the outlets at all times. However, 
on open decks where no protection is afforded to the hose in heavy 
weather, or where the hose may be liable to damage from the handling of 
cargo, the hose may be temporarily removed from the hydrant and stowed 
in an accessible nearby location.
    (i) Each firehose on each hydrant must have a combination solid 
stream and water spray firehose nozzle approved under subpart 162.027 of 
this chapter. Firehose nozzles previously approved under subpart 162.027 
of this chapter may be retained so long as they are maintained in good 
condition to the satisfaction of the Officer in Charge, Marine 
Inspection.
    (j) In each propulsion machinery space containing an oil fired 
boiler, internal combustion machinery, or oil fuel unit on a vessel on 
an international voyage or of 1000 gross tons or more, each firehose 
having a combination nozzle previously approved under subpart 162.027 of 
this chapter must have a low-velocity water spray applicator that is 
also previously approved under subpart 162.027 of this chapter. The 
length of the applicator must be less than 1.8 meters (6 feet).
    (k) Fixed brackets, hooks, or other means for stowing an applicator 
must be next to each fire hydrant that has an applicator under paragraph 
(j) of this section.
    (l) Firehose must not be used for any other purpose than fire 
extinguishing, drills, and testing.
    (m) Fire hydrants, nozzles, and other fittings must have threads to 
accommodate the hose connections noted in paragraph (l) of this section.
    (n) Firehose and couplings must be as follows:
    (1) Fire station hydrant connections must be brass, bronze, or other 
equivalent metal. Couplings must either:

[[Page 47]]

    (i) Use National Standard firehose coupling threads for the 1\1/2\ 
inch (38 millimeter) and 2\1/2\ inch (64 millimeter) hose sizes, i.e., 9 
threads per inch for 1\1/2\ inch hose, and 7\1/2\ threads per inch for 
2\1/2\ inch hose; or
    (ii) Be a uniform design for each hose diameter throughout the 
vessel.
    (2) Where 19 millimeters (\3/4\ inch) hose is permitted by table 
95.10-5(a), the hose and couplings must be of good commercial grade.
    (3) Each section of firehose must be lined commercial firehose that 
conforms to Underwriters' Laboratories, Inc. Standard 19 or Federal 
Specification ZZ-H-451E. Hose that bears the label of Underwriters' 
Laboratories, Inc. as lined firehose is accepted as conforming to this 
requirement.

Sec. 95.10-15  Piping.

    (a) All piping, valves, and fittings shall meet the applicable 
requirements of subchapter F (Marine Engineering) of this chapter.
    (b) All distribution cut-off valves shall be marked as required by 
Sec. 97.37-10 of this subchapter.
    (c) For vessels on an international voyage, the diameter of the fire 
main shall be sufficient for the effective distribution of the maximum 
required discharge from two fire pumps operating simultaneously. This 
requirement is in addition to Sec. 95.10-5(c). The discharge of this 
quantity of water through hoses and nozzles at a sufficient number of 
adjacent hydrants shall be at a minimum Pitot tube pressure of 
approximately 50 pounds per square inch.



Sec. 95.10-90  Installations contracted for prior to May 26, 1965.

    Installations contracted for prior to May 26, 1965, shall meet the 
following requirements:
    (a) Except as specifically modified by this paragraph, the 
requirements of Sec. Sec. 95.10-5 through 95.10-15 shall be complied 
with insofar as the number and general type of equipment is concerned. 
Existing equipment, except firehose nozzles and low-velocity water spray 
applicators, previously approved, but not meeting the applicable 
requirements of Sec. Sec. 95.10-5 through 95.10-15 may be continued in 
service so long as they are maintained in good condition to the 
satisfaction of the Officer in Charge, Marine Inspection. Minor repairs, 
alterations, and replacements may be permitted to the same standards as 
the original installations. However, all new installations or major 
replacements shall meet the applicable requirements in this subpart.
    (b) All vessels contracted for prior to November 19, 1952, other 
than motorboats, shall be fitted with fire pumps, hoses, and nozzles in

  sufficient to assure coverage of all parts of the vessel.
\2\ May use 50 feet of 2\1/2\-inch hose with \7/8\-inch nozzles for
  exterior stations. 75 feet of 1\1/2\-inch hose with \5/8\-inch nozzles
  may be used for interior station in which case such interior stations
  shall have siamese connections.

    (c) Vessels contracted for prior to July 1, 1935, need not meet the 
requirements of Sec. 95.10-5(h), and vessels contracted for on or after 
July 1, 1935, but prior to November 19, 1952, may have a carbon dioxide 
``bilge'' in lieu of ``total flooding'' system. However, in vessels of 
both categories where a conversion from coal to oil is contracted for on 
or after November 19, 1952, the provisions of Sec. 95.10-5(h) shall 
apply.
    (d) The general requirements of Sec. 95.10-5(c) through (g), Sec.

       Subpart 95.15_Carbon Dioxide Extinguishing Systems, Details



Sec. 95.15-1  Application.

    (a) Where a carbon dioxide extinguishing system is installed, the 
provisions of this subpart, with the exception of Sec. 95.15-90, shall 
apply to all installations contracted for on or after November 19, 1952. 
Installations contracted for prior to November 19, 1952, shall meet the 
requirements of Sec. 95.15-90.
    (b) The requirements of this subpart are based on a ``high pressure 
system,'' i.e., one in which the carbon dioxide is stored in liquid form 
at atmospheric temperature. Details for ``low pressure systems,'' i. e., 
those in which the carbon dioxide is stored in liquid form at a 
continuously controlled low temperature, may be specifically approved by 
the Commandant where it is demonstrated that a comparable degree of 
safety and fire extinguishing ability is achieved.



Sec. 95.15-5  Quantity, pipe sizes, and discharge rates.

    (a) General. The amount of carbon dioxide required for each space 
shall be as determined by paragraphs (b) through (d) of this section.
    (b) Total available supply. A separate supply of carbon dioxide need 
not be provided for each space protected. The total available supply 
shall be at least sufficient for the space requiring the greatest 
amount.
    (c) Cargo spaces. (1) The number of pounds of carbon dioxide 
required for each space shall be equal to the gross volume of the space 
in cubic feet divided by 30.
    (2) Although separate piping shall be led to each cargo hold and 
'tween deck, for the purpose of determining the amount of carbon dioxide 
required, a cargo compartment will be considered as the space between 
watertight or firescreen bulkheads and from the tank top or lowest deck 
to the deck head of the uppermost space on which cargo may be carried. 
If a trunk extends beyond such deck, the trunk volume shall be included. 
Tonnage openings shall be considered as sealed for this purpose.
    (3) Branch lines to the various cargo holds and 'tween decks shall 
not be less than \3/4\-inch standard pipe size.
    (4) No specific discharge rate need be applied to such systems.
    (d) Machinery spaces, paint lockers, tanks, and similar spaces. (1) 
Except as provided in paragraph (d)(3) of this section, the number of 
pounds of carbon dioxide required for each space shall be equal to the 
gross volume of the space divided by the appropriate factor noted in 
Table 95.15-5(d)(1). If fuel can drain from the compartment being 
protected to an adjacent compartment, or if the compartments are not 
entirely separate, the requirements for both compartments shall be used 
to determine the amount of carbon dioxide to be provided. The carbon 
dioxide shall be arranged to discharge into both such compartments 
simultaneously.

    (2) For the purpose of the requirements of this paragraph, the 
volume of the machinery space shall be taken as exclusive of the normal 
machinery casing unless the boiler, internal combustion machinery, or 
fuel oil installation

[[Page 49]]

extend into such space, in which case the volume shall be taken to the 
top of the casing or the next material reduction in casing area, 
whichever is lower. For installations contracted for on or after October 
1, 1959, ``normal machinery casing'' and ``material reduction in casing 
area'' shall be defined as follows:
    (i) By ``normal machinery casing'' shall be meant a casing the area 
of which is not more than 40 percent of the maximum area of the 
machinery space.
    (ii) By ``material reduction in casing area'' shall be meant a 
reduction to at least 40 percent of the casing area.
    (3) For vessels on an international voyage contracted for on or 
after May 26, 1965, the amount of carbon dioxide required for a space 
containing propulsion boilers or internal combustion propulsion 
machinery shall be as given by paragraphs (d) (1) and (2) of this 
section or by dividing the entire volume, including the casing, by a 
factor of 25, whichever is the larger.
    (4) Branch lines to the various spaces shall be as noted in Table 
95.15-5(d)(4).

    (5) Distribution piping within the space shall be proportioned from 
the supply line to give proper distribution to the outlets without 
throttling.
    (6) The number, type, and location of discharge outlets shall be 
such as to give a uniform distribution throughout the space.
    (7) The total area of all discharge outlets shall not exceed 85 
percent nor be less than 35 percent of the nominal cylinder outlet area 
or the area of the supply pipe, whichever is smaller. The nominal 
cylinder outlet area in square inches shall be determined by multiplying 
the factor 0.0022 by the number of pounds of carbon dioxide required, 
except that in no case shall this outlet area be less than 0.110 square 
inches.
    (8) The discharge of at least 85 percent of the required amount of 
carbon dioxide shall be complete within 2 minutes.
    (e) Spaces specially suitable for vehicles. (1) The number of pounds 
of carbon dioxide required must be equal to the gross volume of the

Sec. 95.15-10  Controls.

    (a) Except as noted in Sec. 95.15-20(b) all controls and valves for 
the operation of the system shall be outside the space protected, and 
shall not be located in any space that might be cut off or made 
inaccessible in the event of fire in any of the spaces protected.
    (b) If the same cylinders are used to protect more than one hazard, 
a manifold with normally closed stop valves shall be used to direct the 
carbon dioxide into the proper space. If cylinders are used to protect 
only one hazard, a normally closed stop valve shall be installed between 
the cylinders and the hazard except for systems of the type indicated in 
Sec. 95.15-5(d) which contain not more than 300 pounds of carbon 
dioxide.
    (c) Distribution piping to the various cargo spaces shall be 
controlled from not more than two stations. One of the stations 
controlling the system for the main machinery space shall be located as 
convenient as practicable to one of the main escapes from the space. All 
control stations and the individual valves and controls shall be marked 
as

[[Page 50]]

required by Sec. Sec. 97.37-10 and 97.37-13 of this subchapter.
    (d) Systems of the type indicated in Sec. 95.15-5(d) shall be 
actuated by one control operating the valve to the space and a separate

systems for tanks, which are of more than 300 pounds of carbon dioxide, 
shall be fitted with an approved delayed discharge so arranged that the 
alarm will be sounded for at least 20 seconds before the carbon dioxide 
is released into the space. Such systems of not more than 300 pounds of 
carbon dioxide shall also have a similar delayed discharge, except for 
those systems for tanks and for spaces which have a suitable horizontal 
escape. This paragraph shall be applicable only to systems installed on 
or after July 1, 1957.
    (g) All distribution valves and controls shall be of an approved 
type. All controls shall be suitably protected.
    (h) Complete but simple instructions for the operation of the 
systems must be located in a conspicuous place at or near all pull 
boxes, stop valve controls and in the CO2 cylinder storage 
room. On systems in which the CO2 cylinders are not within 
the protected space, these instructions must also include a schematic 
diagram of the system and instructions detailing alternate methods of 
discharging the system should the manual release or stop valve controls 
fail to operate. Each control valve to branch lines must be marked to 
indicate the related space served.
    (i) If the space or enclosure containing the carbon dioxide supply 
or controls is to be locked, a key to the space or enclosure shall be in 
a break-glass-type box conspicuously located adjacent to the opening.

Subpart D_Certificates Under International Convention for Safety of Life 
                              at Sea, 1974



Sec. 107.401  Purpose and definition.

    (a) The International Convention for Safety of Life at Sea, 1974, 
requires one or more of the certificates described in this subpart to be 
carried on self-propelled vessels of 500 gross tons or over engaged in 
international voyages. This subpart prescribes rules for the issuance of 
these certificates to mobile offshore drilling units.
    (b) ``International voyage'' has the same meaning as stated in 
Regulation 2(d) of part A, chapter I in the International Convention for 
Safety of Life at Sea, 1974. (SOLAS 74), which is: ``a voyage from a 
country to which the present Convention applies to a port outside such 
country, or conversely. The Coast Guard has interpreted this definition 
to include the following:
    (1) A voyage from a country to which SOLAS 1974 applies, to a port 
outside that country or the reverse;
    (2) A voyage from any territory, including the Commonwealth of 
Puerto Rico, all possessions of the United States, and all lands held by 
the United States under a protectorate or mandate, whose international 
relations are the responsibility of a contracting SOLAS 74 government, 
or which is administered by the United Nations, to a port outside that 
territory or the reverse;

The Coast Guard has interpreted this definition to not include a ``Great 
Lakes voyage'' which means a voyage solely on the Great Lakes of North 
America and the St. Lawrence River west of a straight line drawn from

[[Page 119]]

Capedes Rosiers to West Point, Anticosti Island and, on the north side 
of Anticosti Island, the 63rd Meridian.

30662, July 26, 1990]



Sec. 107.405  Safety Equipment Certificate.

    (a) A self-propelled unit of at least 500 gross tons that engages in 
international voyages is issued a safety equipment certificate if the 
inspector issues it a certificate of inspection under Sec. 107.211 or 
Sec. 107.215 and it meets chapter 3 of the International Convention for 
Safety of Life at Sea, 1974.
    (b) A Safety Equipment Certificate expires 60 months after the date 
of issue.

[CGD 73-251, 43 FR 56802, Dec. 4, 1978, as amended by CGD 90-008, 55 FR

Sec. 107.409  Safety Construction Certificate.

    (a) Application for a Safety Construction Certificate is made by 
indicating in the space provided on the Application for Inspection Form 
CG-3752 whether the American Bureau of Shipping or the Coast Guard is to 
issue the certificate.
    (b) The American Bureau of Shipping or the Coast Guard may issue a 
self-propelled unit of at least 500 gross tons that engages on 
international voyages a Safety Construction Certificate if the unit 
meets the requirements in Regulation 12 (a)(ii), Chapter I of the 
International Convention for Safety of Life at Sea, 1974.
    (c) A Safety Construction Certificate expires 60 months after the 
date of issue.
    (d) If a unit fails to meet the requirements in Regulation 
12(a)(ii), the Coast Guard may--
    (1) Suspend an unexpired Safety Construction Certificate; and
    (2) Revoke an unexpired Safety Construction Certificate.

Sec. 107.413  Exemption certificate.

    (a) An owner or operator of a unit may request an exemption from the 
requirements of the International Convention for Safety of Life at Sea, 
1974 (SOLAS 74) by writing to the appropriate OCMI.
    (b) The Commandant (CG-CVC) may exempt a self-propelled unit of at 
least 500 gross tons on an international voyage from any of the 
requirements in the International Convention for Safety of Life at Sea, 
1974 (SOLAS 74) if the unit meets the conditions of Regulation 4 of Part 
A, Chapter I, of SOLAS 74 which states the following:

    a. A ship which is not normally engaged on international voyages but 
which, in exceptional circumstances, is required to undertake a single 
international voyage may be exempted by the Administration from any of 
the requirements of the present Regulations provided that it complies 
with safety requirements which are adequate in the opinion of the 
Administration for the voyage which is to be undertaken by the ship.
    b. The Administration may exempt any ship which embodies features of 
a novel kind from any of the provisions of Chapters II-1, II-2, III and 
IV of these Regulations the application of which might seriously impede 
research into the development of such features and their incorporation 
in ships engaged on international voyages. Any such ship shall, however, 
comply with safety requirements which, in the opinion of that 
Administration, are adequate for the service for which it is intended 
and are such as to ensure the overall safety of the ship and which are 
acceptable to the Governments of the States to be visited by the ship. 
The Administration which allows any such exemption shall communicate to 
the Organization particulars of same and the reasons therefor which the 
Organization shall circulate to the Contracting Governments for their 
information.

    (c) The Commandant (CG-CVC) may exempt a self-propelled unit of at 
least 500 gross tons on an international voyage from the requirements of 
Chapter III (Lifesaving Appliances, &C.) of SOLAS 74 if the unit meets 
the conditions of Regulation 2 of chapter III which states in part:

    The Administration may, if it considers that the sheltered nature 
and conditions of the voyage are such as to render the application of 
any specific requirements of this chapter unreasonable or unnecessary, 
exempt from those requirements individual ships or classes of ships 
which, in the course of their voyage, do not proceed more than 20 miles 
from the nearest land.

    (d) The Commandant (CG-CVC) may exempt a unit from the requirements 
of

[[Page 120]]

Chapters II-1 (Construction--Subdivision and stability, machinery and 
electrical installations) or II-2 (Construction--Fire protection, fire 
detection and fire extinction) of SOLAS 74 if the unit meets the 
conditions of Regulation 1-4 of Part A Chapter II-1 or Regulation 1-4.1 
of Part A Chapter II-2, respectively, of SOLAS 74 which state the 
following: The Administration of a State may, if it considers that the 
sheltered nature and conditions of the voyage are such as to render the 
application of any specific requirements of this chapter unreasonable or 
unnecessary, exempt from those requirements individual ships or classes 
of ships entitled to fly the flag of the State which, in the course of 
their voyage, do not proceed more than 20 miles from the nearest land.
    (e) An Exemption Certificate is in force for the period of validity 
of the certificate to which it refers.

 Sec. Appendix A to Part 109--Navigation and Vessel Inspection Circular 
   No. 4-78--Inspection and Certification of Existing Mobile Offshore 
                             Drilling Units

    1. Purpose. To promulgate instructions for the inspection and 
certification of existing mobile offshore drilling units. This NVIC is 
also being published as appendix A of 46 CFR Subchapter IA.
    2. Background. Mobile Offshore Drilling Units are recognized 
internationally through the Intergovernmental Maritime Consultative 
Organization as being a ``special purpose ship'' designed and operated 
to carry out an industrial function at sea. Contemporary U.S. Vessel 
regulations in Title 46 CFR do not adequately cover the safety 
considerations which are unique to the hull and structural designs, 
industrial equipment and operating procedures incorporated in drilling 
vessels. To provide appropriate and adequate standards, the Coast Guard 
with the assistance of the National Offshore Operations Advisory 
Committee, and following the provisions of the Administrative Procedures 
Act, developed Subchapter IA, Regulations for Mobile Offshore Drilling 
Units, 46 CFR Parts 107-109 and amendments to 46 CFR Subchapters ``F'', 
Marine Engineering Regulations, and ``J'', Electrical Engineering 
Regulations. These regulations, published in Federal Register (43 FR 
56788 December 4, 1978) will apply to all units contracted for on or 
after the effective date of the regulations.
    3. Discussion. a. This NVIC elaborates the ``grandfather 
provisions'' of 46 CFR 107.211 and 107.215 in applying Subchapter IA to 
the approximately 150 existing ocean-going U.S. flag mobile offshore 
drilling units. ``Existing'' Mobile Offshore Drilling Units are those 
vessels which have been contracted for before the effective date of the 
regulations including:
    (1) Units in Service.
    (2) Units under construction.
    (3) Units contracted for which are to be constructed and delivered 
prior to January 1, 1981.
    b. Existing uncertificated mobile drilling units of which there are 
approximately 92 of the bottom bearing configuration, i.e., jack-up and 
submersible types, have not previously been required to comply with 
vessel inspection regulations. Some units have met the load line 
requirements of Subchapter ``E'' for International Voyages. Many of the 
older units are not classed by a classification society. Bottom bearing 
units operating on the Outer Continental Shelf of United States have 
been required to meet the safety requirements of 33 CFR Subchapter ``N'' 
as artificial islands. On January 3, 1979, existing bottom bearing units 
are subject to the ``grandfather provisions'' in Sec. 107.211(c) of 
Subchapter IA.
    c. Existing certificated mobile offshore drilling units, for the 
purposes of this NVIC, are column-stabilized and ship-shape types of 
which approximately 58 are currently certificated, or have made 
application for an original Certificate of Inspection or intend to make 
application for an original inspection for certification under 46 CFR 
Subchapter ``I'' on the basis of the unit being contracted for prior to 
the effective date of the new regulations. These units may continue to 
meet the structural, equipment, material and arrangement standards which 
were applicable to the hull, engineering, electrical and industrial 
systems when the units were contracted for. In addition they must meet 
the provisions of d.(1), d.(4)(d), d.(7)(b), d.(8), d.(9), d.(10)(b), 
d.(11) and d.(12) of paragraph 3 of this NVC in accordance with Sec. 
107.215(c)(2) of Subchapter IA.
    d. Inspection Provisions for Existing Uncertificated Units. The 
intent of the ``grandfather'' provisions of this NVIC for existing 
uncertificated units is to ascertain through inspection that the 
material condition of the unit and its equipment meet reasonable levels 
of safety. To this end, the following determinations will be made:
     The design, construction and arrangements of the 
hull, machinery electrical and industrial systems do not reveal 
manifestly unsafe aspects.
     There is no excessive deterioration of the hull 
structure or equipment foundations.
     There are no intrinsic fire or explosion hazards.
     There are no personnel hazards such as unguarded 
moving machinery, potential electrical shock conditions or lack of 
handrails.
     The unit is seaworthy and exhibits satisfactory 
stability.
    (1) General. (a) Repairs and minor alterations to hull structure or 
equipment may be made to the same standards as the original 
installation. However, new installations or major alterations which 
affect vessel or personnel safety shall meet the applicable standards of 
Subchapter IA.
    (b) Existing items of safety equipment not meeting the applicable 
specifications or requirements set forth in Subchapter IA may be 
continued in service as long as they are

[[Page 180]]

maintained in good working order to the satisfaction of the OCMI. Such 
safety equipment and installations requiring extensive repairs shall be 
replaced and shall meet the applicable specifications and requirements 
of Subchapter IA.
    (c) The OCMI has discretion to accept alternatives or equivalents 
which meet the established standards, and to give special consideration 
to departures from the regulations when it can be shown that special 
circumstances warrant such departures.
    (2) Plan Submittal. (a) For units not classed by the American Bureau 
of Shipping or other recognized classification society, (see 46 CFR 
108.109) the OCMI must have sufficient plans and information submitted 
to him which will describe such things as the unit's size, construction, 
configuration, arrangement of tanks, decks and spaces; and the machinery 
and electrical installation. In addition, the OCMI may require submittal 
of any additional data he considers necessary in order to proceed with 
the original inspections.
    (b) For units classed by the American Bureau of Shipping or other 
recognized classification society, the plans and information described 
in Subchapter IA Sec. 107.305 (a), (b), (v), and (ii) and a general 
description of the machinery and electrical installation shall be 
submitted to the OCMI for information. The OCMI may accept continued 
classification as proof of structural, mechanical, and electrical 
sufficiency. However, the OCMI may require additional plans and 
information if necessary.
    (3) Hull Structure. (a) No structural changes will be required 
unless manifestly unsafe conditions exist.
    (b) Existing uncertificated units must be drydocked or have a 
special examination in lieu of drydocking as required by 46 CFR, 107-
261.
    (c) Achievement of one compartment subdivision is not required where 
extensive modification of the original design would be necessary; 
however, watertight integrity of the hull and structural boundaries must 
be maintained. Bulkheads and decks designed to be watertight must be 
maintained as such where they are penetrated by pipes, electrical cable, 
reach rods, ventilation systems, etc.
    (4) Stability. (a) The stability of each existing unit will be 
reviewed by the Coast Guard. The plans indicated in 46 CFR Subchapter IA 
Sec. 107.305(q) through (u-l) must be submitted to the cognizant OCMI 
or Merchant Marine Technical Office.
    (b) Lightship data from a Coast Guard witnessed and approved 
stability test is required for each existing, uncertificated unit. 
Alternatively other evidence of lightship values will be considered on a 
case by case basis.
    (c) In general, compliance with the intact stability standards of 46 
CFR Subchapter IA, Sec. Sec. 108.303 through 108.309 is required. Where 
existing units were designed to a lesser standard of stability than that 
specified in Sec. Sec. 108.303 through 108.309, some relaxation based 
on proven past performance may be granted at the discretion of the OCMI 
and limiting conditions, if any, set forth in the operating manual. In 
no case will the minimum wind speed for adequate stability be reduced 
below 50 knots.
    (d) An operating manual shall be prepared for each unit. Each 
operating manual must contain the information indicated in 46 CFR 
Subchapter IA, Sec. 109.121(d) and be submitted to the cognizant OCMI 
or Merchant Marine Technical Office for review.
    (5) Load Line. (a) All units are required to obtain and maintain a 
valid Load Line Certificate. The structure and stability of the unit 
must be proven adequate for the voyages and areas of operation intended.
    (b) The American Bureau of Shipping or other recognized 
classification society will issue Load Line Certificates and conduct 
initial and annual load line surveys. Coast Guard and the American 
Bureau of Shipping inspections may be conducted simultaneously, but it 
is the owner's responsibility to arrange coordinated inspection 
schedules.
    (c) The structural review conducted by the American Bureau of 
Shipping or other recognized classification society for load line 
assignment may be accepted by the Coast Guard as proof of structural 
adequacy of the hull.
    (d) The stability review must be completed prior to issuance of a 
Load Line Certificate. The Coast Guard will inform the American Bureau 
of Shipping or other recognized classification society of the results of 
the stability review, and will indicate any stability limitations to be 
placed on the Load Line Certificate.
    (e) Freeboard calculations for self-elevating units with barge type 
hulls will be made in accordance with 46 CFR, Part 42. The bow height 
requirements of 46 CFR 42.20-70 may be relaxed to approximately 33% of 
the normal requirement for barge shapes moving at speeds less than 6 
knots. No relaxation of the addition to freeboard for deficiency in 
sheer is allowed. The freeboard for units other than self-elevating 
units with barge type hulls will be based upon compliance with the 
intact and damage stability standards applicable at the time the unit 
was contracted for.
    (f) All units delivered after the date of this NVIC regardless of 
contract date, must obtain a Load Line Certificate as soon as 
operationally feasible.
    (6) Route and Operating Area Limitations. (a) Units classed by the 
American Bureau of Shipping or other recognized classification society 
for ocean service generally will be certificated by the Coast Guard for 
ocean routes.

[[Page 181]]

    (b) Unclassed units which have proven structural and stability 
adequacy by continued safe operation in a specific geographic area, such 
as the Gulf of Mexico, will be limited by the Certificate of Inspection 
and Load Line Certificate to that area. To qualify for an unlimited 
oceans route, such a unit must be reviewed for adequacy of the structure 
and stability by the Coast Guard and meet the Load Line requirements of 
d. (5) above.
    (c) Any unit which intends to move or operate outside the 
geographical area indicated on the Certificate of Inspection must 
receive prior approval from the OCMI.
    (7) Fire Protection. (a) Structural fire protection. All units must 
meet the provisions of Sec. 108.123, Insulation of Combustible 
Materials and Sec. 108.127, Storage Lockers for Combustibles. All 
existing interior stairways which are open at each end must be enclosed 
at one level. On units where wood was utilized in the construction of 
accommodation spaces, each space must be equipped with a smoke or heat 
detector either battery powered or operating on the AC power supply. All 
detectors must have the Underwriters Laboratories, Inc., label (UL) or 
the Factory Mutual Laboratories (FM) label.
    (b) Fire Extinguishing Systems. Systems and equipment must be 
provided which will meet or be equivalent to the applicable 
specifications and provisions required by Subchapter IA. Installed fire 
extinguishing systems, which provide equivalent or greater protection 
than systems required by Subpart E, Subchapter IA may be continued in 
use as long as they are in good material condition and will function as 
designed. Where practicable, existing washdown systems may be utilized 
as the firemain. Where wood was utilized in the construction of 
accommodation spaces, the applicable requirements of 46 CFR Subchapter 
IA, Table 108.495(a) should be doubled.
    (8) Lifesaving Equipment. (a) Each unit must have lifesaving 
equipment (lifeboats and davit launched liferafts) for 200 percent of 
the total persons allowed on board. Except for submersible type units, 
the installation of lifeboats for 100 percent of the persons (on board) 
is required in accordance with 46 CFR 108.503 of Subchapter IA. 
Consideration will be given to those units where existing arrangement 
and structure do not provide sufficient room for installation of the 
lifeboats or where the added weight of the lifeboats, davits and winches 
will materially reduce the variable load capacity of the unit. In such 
cases, davit launched inflatable liferafts with a combined personnel 
capacity of the required lifeboats, and a rescue boat approved by the 
OCMI may be acceptable equivalents. Submersible type units may 
substitute Coast Guard approved throw over type inflatable liferafts and 
an approved rescue boat for the required lifeboats.
    (b) For the second part of the total 200 percent primary lifesaving 
requirement, lifeboats installed in accordance with 33 CFR, Subchapter 
``N'' Part 144 or Coast Guard approved life floats may be retained as 
provided for in 3.d(1)(b) of this Circular. They will be considered 
collectively with the Coast Guard approved liferafts for calculating the 
amount of equipment to provide for 100 percent of personnel on board.
    (c) Adequate access to all lifesaving equipment must be provided.
    (9) Cranes. (a) Plan approval will not normally be required of any 
crane which conforms to the specifications of the manufacturer as 
originally installed. A rated load test as described in Sec. 107.260 of 
Subchapter IA will be required unless the crane has been load tested 
while under certification by an approved certifying authority as 
provided for in 46 CFR 107.258. Prior to the rated load test, the crane 
should be identified by manufacturer and model number to determine that 
the correct load rating chart is being used. The owner must submit to 
the OCMI details and calculations of any alterations to a crane which 
were accomplished without manufacturer's documentation in order to 
verify the rated load of the crane.
    (10) Electrical. (a) Multiple power sources do not require an 
emergency generator; however, storage batteries or approved relay-
controlled battery operated lanterns are required to be installed for 
the emergency lighting system and provide 12 hours of lighting.
    (b) Electrical equipment installed in Class I, division 1 and 2 
locations, as defined in Subchapter IA, Sec. 108.170 must be of a 
suitable type and in good material condition.
    (11) Unfired Pressure Vessels. (a) Unfired pressure vessels built 
and stamped in accordance with Section VIII of the ASME Code may be 
continued in service as long as they remain in satisfactory condition. 
At the original and subsequent inspections for certification, ASME Code 
pressure vessels must be tested and examined in accordance with the 
requirements in 46 CFR 61.10-5.
    (b) Unfired pressure vessels which cannot be identified as being 
constructed to any recognized standard may be continued in service 
provided that no obvious defects are noted. These pressure vessels shall 
be hydrostatically tested to one and one half times the working 
pressure. For pressure vessels that can not be reasonably 
hydrostatically tested, nondestructive testing may be used to verify the 
pressure vessels condition for continued serviceability. These pressure 
vessels will then be stamped with a Coast Guard identification number 
and periodically tested and examined in accordance with the requirements 
in 46 CFR 61.10-5.
    (12) Marine Sanitation Devices. (a) All units must meet the 
provisions of 33 CFR Part 159,

[[Page 182]]

Coast Guard Marine Sanitation Devices Regulations. The discharge 
requirements are compatible with the OCS Orders of the U.S. Geological 
Survey.
    4. Action. a. The owner of each existing certificated unit must 
provide the cognizant OCMI a proposed plan to accomplish the 
requirements in paragraph 3. c. of this NVIC within 60 days from the 
effective date of the regulations. Most items should be approved at the 
unit's next inspection for certification; however, where major equipment 
installations are concerned, the owner may be allowed up to two years to 
comply with the requirements from the time the OCMI completes his 
assessment of the proposals.
    b. Application for Original Inspection for Certification. Not later 
than sixty days from January 3, 1979, application for original 
inspection for certification of all existing uncertificated units, shall 
be submitted to the appropriate OCMI. The plans or descriptive data 
specified in paragraph 3.d(2) of this NVIC along with a proposed plan to 
bring the unit into compliance should, if possible, be submitted with 
the application for inspection. If not feasible to assemble all required 
information in this time frame, an estimated date of submittal shall be 
indicated on the application. Arrangements should be made to commence 
the original inspection for certification with due consideration for the 
unit's operating situation.
    c. To the extent possible the same inspection team will conduct the 
inspection of all existing uncertificated units in a geographical area. 
It may be advantageous to conduct the original inspection in conjunction 
with an impending special or periodic survey, drydocking or availability 
period. Units under construction will receive primary consideration by 
the OCMI for the allocation of time and personnel so that any problems 
can be identified while the unit is in the most advantageous situation 
to apply corrections.
    d. The variety of designs and arrangements presented by existing 
uninspected MODU's makes it impractical to prescribe detailed standards 
for all existing units. The procedures followed to implement this NVC 
must provide the necessary flexibility. Items which must be taken into 
consideration in applying this NVIC are listed below. Categorizing units 
into groups to which the same items apply will be of value during the 
inspection process. These items are:
     Type
     Builder
     Model
     Date build
     Classed by ABS or other classification society
     Load Line assignment
     Operating history (including geographical areas)
     Present location
    e. Issuance of the Original Certificate of Inspection. The intent of 
the original inspection of existing uncertificated units is to identify 
and commence correction of any unsafe conditions and/or equipment 
deficiencies and to issue the unit an original Certificate of 
Inspection. A reasonable period of time will be permitted to correct 
minor deficiencies. Those items directly affecting personnel safety and 
health will require immediate attention to correct the unsafe condition. 
Extensive deficiencies, such as those involving structural aspects or 
equipment may require up to two years to remedy. Additional times may be 
allowed if repair facilities are not available to coastal areas adjacent 
to the unit's area of operation. Where manifestly unsafe conditions are 
found, the OCMI may require that the unit discontinue operations until 
such conditions are corrected. If the owner or operator feels aggrieved 
by the decision of the OCMI, the appeals procedures of 46 CFR 2.01-70 
are applicable.
    f. Questions concerning this NVIC should be referred to the 
Commandant (CG-CVC).

 Subpart 111.05_Equipment Ground, Ground Detection, and Grounded Systems



Sec. 111.05-1  Purpose.

    This subpart contains requirements for the grounding of electric 
systems, circuits, and equipment.
    Note: Circuits are grounded to limit excessive voltage from 
lightning, transient surges, and unintentional contact with higher 
voltage lines, and to limit the voltage to ground during normal 
operation. Conductive materials enclosing electric conductors and 
equipment, or forming part of that equipment, are grounded to prevent a 
voltage above ground on the enclosure materials.

    (a) The aggregate capacity of the electric ship's service generating 
sources required in Sec. 111.10-3 must be sufficient for the ship's 
service loads.
    (b) With the ship's service generating source of the largest 
capacity stopped, the combined capacity of the remaining electric ship's 
service generating source or sources must be sufficient to supply those 
services necessary to provide normal operational conditions of 
propulsion and safety, and minimum comfortable conditions of 
habitability. Habitability services include cooking, heating, air 
conditioning (where installed), domestic refrigeration, mechanical 
ventilation, sanitation, and fresh water.
    (c) The capacity of the ship's service generating sources must be 
sufficient for supplying the ship's service loads without the use of a 
generating source which is dependent upon the speed or direction of the 
main propelling engines or shafting.
    (d) Operating generators must provide a continuous and uninterrupted 
source of power for the ship's service load under normal operational 
conditions. Any vessel speed change or throttle movement must not cause 
a ship's service load power interruption.
    (e) Vessels with electric propulsion that have two or more constant-
voltage generators which supply both ship's service and propulsion power 
do not need additional ship's service generators provided that with any 
one propulsion/ship's service generator out of service the capacity of 
the remaining generator(s) is sufficient for the electrical loads 
necessary to provide normal operational conditions of propulsion and 
safety, and minimum comfortable conditions of habitability.
    (f) A generator driven by a main propulsion unit (such as a shaft 
generator) which is capable of providing electrical power continuously, 
regardless of the speed and direction of the propulsion shaft, may be 
considered one of the ship's service generating sets required by Sec. 
111.10-3. A main-engine-dependent generator which is not capable of 
providing continuous electrical power may be utilized as a supplemental 
generator provided that a required ship's service generator or 
generators having sufficient capacity to supply the ship's service loads 
can be automatically brought on line prior to the main-engine-dependent 
generator tripping off-line due to a change in the speed or direction of 
the main propulsion unit.

the electrical services necessary to start the main propulsion plant 
from a dead ship condition.
    (b) If the emergency generator is used for part or all of the 
electric power necessary to start the main propulsion plant from a dead 
ship condition, the emergency generator must be capable of providing 
power to all emergency lighting, emergency internal communications 
systems, and fire detection and alarm systems in addition to the power 
utilized for starting the main propulsion plant. Additional requirements 
are in Sec. 112.05-3(c) of this chapter.

    If transformers are used to supply the ship's service distribution 
system required by this subpart for ships and mobile offshore drilling 
units, there must be at least two installed, independent power 
transformers. With the largest transformer out of service, the capacity 
of the remaining units must be sufficient to supply the ship service 
loads.

    Note to Sec. 111.10-9: A ship's service supply system would consist 
of transformers, overcurrent protection devices, and cables, and would 
normally be located in the system between a medium voltage bus and a low 
voltage ship's service switchboard. It is not the intent, nor is it 
required, that transformers

[CGD 94-108, 61 FR 28279, June 4, 1996]



Sec. 111.50-3  Protection of conductors.

    (a) Purpose. The purpose of overcurrent protection for conductors is 
to open the electric circuit if the current reaches a value that will 
cause an excessive or dangerous temperature in the conductor or 
conductor insulation. A grounded conductor is protected from overcurrent 
if a protective device of a suitable rating or setting is in each 
ungrounded conductor of the same circuit.
    (b) Overcurrent protection of conductors. Each conductor must be 
protected in accordance with its current carrying capacity, except a 
conductor for the following circuits which must meet the following 
listed subparts:
    (1) Propulsion circuits, subpart 111.35.
    (2) Steering circuits, subpart 58.25 of this chapter.
    (3) Motor circuits, subpart 111.70.
    (4) Flexible cord and fixture wire for lighting circuits, subpart 
111.75.
    (5) Switchboard circuits, subpart 111.30.
    (c) Fuses and circuit breakers. If the allowable current-carrying 
capacity of the conductor does not correspond to a standard rating for 
fuses or circuit breakers that meets Section 240.6 of NFPA 70 
(incorporated by reference; see 46 CFR 110.10-1), then the next larger 
such rating is acceptable, except that:
    (1) This rating must not be larger than 150 percent of the current-
carrying capacity of the conductor; and
    (2) The effect of temperature on the operation of fuses and 
thermally controlled circuit breakers must be taken into consideration.
    (d) Parallel overcurrent protective devices. An overcurrent 
protective device must not be connected in parallel with another 
overcurrent protective device.
    (e) Thermal devices. No thermal cutout, thermal relay, or other 
device not designed to open a short circuit may be used for protection 
of a conductor against overcurrent due to a short circuit or ground, 
except in a motor circuit as described in Article 430 of NFPA 70 or in 
IEC 60092-202:2016 (both incorporated by reference; see Sec. 110.10-1 
of this subchapter).
    (f) Ungrounded conductors. A fuse or overcurrent trip unit of a 
circuit breaker must be in each ungrounded conductor. A branch switch or 
circuit breaker must open all conductors of the circuit, except grounded 
conductors.
    (g) Grounded conductor. An overcurrent device must not be in a 
permanently grounded conductor, except:
    (1) An overcurrent device that simultaneously opens all conductors 
of the circuit, unless prohibited by Sec. 111.05-17 for the bus-tie 
feeder connecting the emergency and main switchboards; and
    (2) For motor-running protection described in Article 430 of NFPA 70 
or in IEC 60092-202:2016 (both incorporated by reference; see Sec. 
110.10-1 of this subchapter).

    (2) The overcurrent protection for the shore connection conductors 
must meet Sec. 111.30-25(f).
    (3) If the overcurrent device that protects the larger conductors 
also protects the smaller conductors, an overcurrent device is not 
required at the supply to the smaller conductors.
    (4) If the overcurrent device protecting the primary side of a 
transformer also protects the conductors connected to the secondary 
side, as determined by multiplying the current-carrying capacity of the 
secondary conductor by the secondary to primary transformer voltage 
ratio, and this protection meets Sec. 111.20-15 of this chapter, an 
overcurrent device is not required at the supply to the secondary side 
conductors.
    (b) Location on vessel. Each overcurrent device:
    (1) Must be:
    (i) Readily accessible; and
    (ii) In a distribution panelboard, switchboard, motor controller, or

2020-0075, 88 FR 16364, Mar. 16, 2023]



Sec. 111.70-3  Motor controllers and motor-control centers.

    (a) General. The enclosure for each motor controller or motor-
control center must meet either NEMA ICS 2 and NEMA ICS 2.3, or Table 1 
of IEC 60092-201:2019 (all incorporated by reference; see Sec. 110.10-1 
of this subchapter), as appropriate, for the location where it is 
installed. In addition, each such enclosure in a hazardous location must 
meet the requirements of subpart 111.105 of this part. NEMA ICS 2.4 
(incorporated by reference; see Sec. 110.10-1 of this subchapter) 
provides guidance on the differences between devices meeting NEMA and 
those meeting IEC for motor service.
    (b) Low-voltage release. Each motor controller for a fire pump, 
elevator, steering gear, or auxiliary that is vital to the vessel's 
propulsion system, except a motor controller for a vital propulsion 
auxiliary which can be restarted from a central control station, must 
have low-voltage release if automatic restart after a voltage failure or 
its resumption to operation is not hazardous. If automatic restart is 
hazardous, the motor controller must have low-voltage protection. Motor 
controllers for other motors must not have low-voltage release unless 
the starting current and the short-time sustained current of the 
additional low-voltage release load is within the capacity of one ship's 
service generator. Automatic sequential starting of low-voltage release 
controllers is acceptable to meet this paragraph.
    (c) Low-voltage protection. Each motor controller must have low-
voltage protection, except for the following motor controllers:
    (1) A motor controller that has low-voltage release under paragraph 
(b) of this section.
    (2) A motor controller for a motor of less than 2 horsepower (1.5 
kW).
    (d) Identification of controllers. (1) Each motor controller and 
motor control center must be marked externally with the following 
information:
    (i) Manufacturer's name or identification.
    (ii) Voltage.

Sec. 111.70-5  Heater circuits.

    (a) If an enclosure for a motor, master switch, or other equipment 
has an electric heater inside the enclosure that is energized from a 
separate circuit, the heater circuit must be disconnected from its 
source of potential by a

[[Page 223]]

disconnect device independent of the enclosure containing the heater. 
The heater disconnecting device must be adjacent to the equipment 
disconnecting device. A fixed sign, warning the operator to open both 
devices, must be on the enclosure of the equipment disconnect device, 
except as in paragraph (b) of this section.
    (b) If the location of the enclosure for a motor, master switch, or 
other equipment for deck machinery is remote from the motor and 
controller disconnect device, a sign must be fixed to the enclosure if 
the disconnect arrangement required by paragraph (a) of this section is 
not used. The sign must warn the operator of the presence of two sources 
of potential within the enclosure and show the location of the heater 
circuit disconnect device.
    (c) Electric heaters installed within motor controllers and 
energized from a separate circuit must be disconnected in the same 
manner as required by paragraph (a) of this section or by Sec. 111.70-
7(d).

28282, June 4, 1996]



Sec. 111.70-7  Remote control, interlock, and indicator circuits.

    (a) Overcurrent protection. A conductor of a control, interlock, or 
indicator circuit of a motor controller must be protected against 
overcurrent unless:
    (1) The conductor is wholly within the controller enclosure;
    (2) The rating or setting of the branch circuit overcurrent device 
is not more than 300 percent of the current-carrying capacity of the 
control, interlock, or indicator circuit conductor;
    (3) There is an overcurrent device in each side of the line that has 
a rating or setting of not more than 300 percent of the current-carrying 
capacity of the control, electrical interlock, or indicator circuit 
conductor, except if under operating conditions there is no appreciable 
difference in potential between the external conductors, overcurrent 
protection need only be at the supply of that side of the line; or
    (4) The opening of the control, interlock, or indicator circuit 
creates a hazard.
    Note: For overcurrent protection of steering gear control and 
indicator circuits, see Subpart 111.93 of this chapter.
    (b) Accidental ground. The controller must be designed to prevent an 
accidental ground in a remote control circuit from causing the stop 
switches to fail to operate or causing the motor to start.
    (c) Source of potential. The potential for a control, interlock, or 
indicator circuit must be derived from the load side of the motor and 
controller disconnect device, except if the control functions require 
circuits that must be common to two or more controllers, the switching 
arrangement in paragraph (d) of this section must be met.
    (d) Switching. In the design of a control, interlock, or indicator 
circuit, all practicable steps must be taken to eliminate all but one 
source of power in an enclosure. If the control functions make it 
impracticable to energize a control interlock or indicator circuit from 
the load side of a motor and controller disconnect device and the 
voltage of the control, interlock, or indicator circuit is more than 24 
volts, there must be one of the following alternative methods of 
switching:
    (1) Each conductor of a control, interlock, or indicator circuit 
must be disconnected from all sources of potential by a disconnect 
device independent of the motor and controller disconnect device. The 
two independent devices must be adjacent to each other, and a fixed 
sign, warning the operator to open both devices to disconnect completely 
the motor and controller, must be on the exterior of the door of the 
main disconnect device.
    (2) Each conductor of a control, interlock, or indicator circuit 
must be disconnected from all sources of power by a disconnect device 
actuated by the opening of the controller door, or the power must first 
be disconnected to allow opening of the door. The disconnect device and 
its connections, including each terminal block for terminating the 
vessel's wiring, must have no electrically uninsulated or unshielded 
surface. When this type of

[[Page 224]]

disconnect device is used for vital auxiliary circuits, a nameplate must 
be affixed to the vital auxiliary motor controller door that warns that 
opening the door will trip a vital auxiliary off-line.

Sec. 111.75-1  Lighting feeders.

    (a) Passenger vessels. On a passenger vessel with fire bulkheads 
forming main vertical and horizontal fire zones, the lighting 
distribution system, including low location egress lighting where 
installed, must be arranged so that, to the maximum extent possible, a 
fire in any main vertical and horizontal fire zone does not interfere 
with the lighting in any other fire zone. This requirement is met if 
main and emergency feeders passing through any zone are separated both 
vertically and horizontally as widely as practicable.
    (b) Machinery spaces. Lighting for enginerooms, boilerrooms, and 
auxiliary machinery spaces must be supplied from two or more feeders.

   Subpart 112.01_Definitions of Emergency Lighting and Power Systems



Sec. 112.01-1  Purpose.

    The purpose of this subpart is to define types of emergency lighting 
and power systems.



Sec. 112.01-5  Manual emergency lighting and power system.

    A manual emergency lighting and power system is one in which a 
single manual operation, such as the manual operation of a switch from 
an ``off'' to an ``on'' position, is necessary to cause the emergency 
power source to supply power to the emergency loads.



Sec. 112.01-10  Automatic emergency lighting and power system.

    An automatic emergency lighting and power system is one in which a 
reduction in potential from the ship's service power and lighting plant 
causes the emergency power source to supply power to the emergency 
loads.



Sec. 112.01-15  Temporary emergency power source.

    A temporary emergency power source is one of limited capacity that 
carries, for a short time, selected emergency loads while an emergency 
power source of larger capacity is being started.



Sec. 112.01-20  Final emergency power source.

    A final emergency power source is one that automatically supplies 
power to the emergency loads under Sec. 112.15-5 and automatically 
transfers the temporary emergency loads under Sec. 112.15-1 when the 
potential of the final emergency source reaches 85 to 95% of normal 
value.

[USCG-2020-0075, 88 FR 16368, Mar. 16, 2023]



                         Subpart 112.05_General



Sec. 112.05-1  Purpose; preemptive effect.

    (a) The purpose of this part is to ensure a dependable, independent, 
and dedicated emergency power source with sufficient capacity to supply 
those services that are necessary for the safety of the passengers, 
crew, and other persons in an emergency and those additional loads that 
may be authorized under paragraph (c) of this section.
    (b) No load may be powered from an emergency power source, except:
    (1) A load required by this part to be powered from the emergency 
power source;
    (2) A bus-tie to the main switchboard that meets Sec. 112.05-3; and
    (3) Emergency loads that may be necessary to maintain or restore the 
propulsion plant, such as control systems, controllable pitch 
propellers, hydraulic pumps, control air compressors, and machinery 
necessary for dead-ship start-up.
    (c) Other loads may be authorized by the Commanding Officer, Marine 
Safety Center (MSC), to be connected to the emergency source of power to 
provide an increased level of safety in recognition of a unique vessel 
mission or configuration. When these loads are authorized, the emergency 
power source must--
    (1) Be sized to supply these loads using a unity (1.0) service 
factor; or
    (2) Be provided with automatic load shedding that removes these 
loads and operates before the emergency generator trips due to overload. 
The automatic load shedding circuit breakers must be manually reset.
    (d) The regulations in this part have preemptive effect over State 
or local regulations in the same field.

33882, June 7, 2012]



Sec. 112.05-3  Main-emergency bus-tie.

    Each bus-tie between a main switchboard and an emergency switchboard 
must:
    (a) Disconnect automatically upon loss of potential at the emergency 
switchboard;
    (b) Be arranged to prevent parallel operation of an emergency power 
source with any other source of electric power, except for interlock 
systems for momentary transfer of loads; and

[[Page 248]]

    (c) If arranged for feedback operation, open automatically upon 
overload of the emergency power source before the emergency power source 
is tripped off the line from the overload.



Sec. 112.05-5  Emergency power source.

    (a) The emergency power source must meet Table 1 to 112.05-5 and 
have the capacity to supply all loads, at a unity (1.0) service factor, 
that are simultaneously connected to it, except a load on a bus-tie to 
the main switchboard or non-required loads that are connected in 
accordance with Sec. 112.05-1(c).

[USCG-1999-4976, 65 FR 6504, Feb. 9, 2000]



Sec. 115.110  Routes permitted.

    (a) The area of operation for each vessel and any necessary 
operational limits are determined by the cognizant OCMI, and recorded on 
the vessel's Certificate of Inspection. Each area of operation, referred 
to as a route, is described on the Certificate of Inspection under the 
major headings ``Oceans,'' ``Coastwise,'' ``Limited Coastwise,'' ``Great 
Lakes,'' ``Lakes, Bays, and Sounds,'' or ``Rivers,'' as applicable. 
Further limitations imposed or extensions granted are described by 
reference to bodies of waters, geographical points, distance from 
geographical points, distances from land, depths of channel, seasonal 
limitations, and similar factors.
    (b) Operation of a vessel on a route of lesser severity than those 
specifically described or designated on the Certificate of Inspection is 
permitted unless expressly prohibited on the certificate of Inspection. 
The general order of severity of routes is: oceans, coastwise, limited 
coastwise, Great Lakes, lakes, bays and sounds, and rivers. The 
cognizant OCMI may prohibit a vessel from operating on a route of lesser 
severity than the primary route a vessel is authorized to operate on if 
local conditions necessitate such a restriction.
    (c) Non-self-propelled vessels are prohibited from operating on an 
oceans, coastwise, limited coastwise, or Great Lakes route unless the 
Commandant approves such a route.
    (d) When designating a permitted route or imposing any operational 
limits on a vessel, the OCMI may consider:
    (1) Requirements of this subchapter for which compliance is based on 
the route of the vessel;
    (2) The performance capabilities of the vessel based on design, 
scantlings, stability, subdivision, propulsion, speed, operating modes, 
maneuverability, and other characteristics;
    (3) The suitability of the vessel for night-time operations; and
    (4) The suitability of the vessel for use in all environmental 
conditions.

[CGD 85-080, 61 FR 892, Jan. 10, 1996, as amended by USCG-2007-0030, 75 
FR 78082, Dec. 14, 2010]



Sec. 115.112  Total persons permitted.

    The cognizant Officer in Charge, Marine Inspection (OCMI) determines 
the total number of persons permitted to be carried on a vessel. In 
determining the total number of persons, the OCMI may consider the total 
weight of passengers, crew, and variable loads; stability restrictions 
and subdivision requirements of the vessel; the vessel's route, general 
arrangement, means of escape, and lifesaving equipment; minimum manning 
requirements; and the maximum number of passengers permitted in 
accordance with Sec. 115.113 of this subpart.

[USCG-2007-0030, 75 FR 78082, Dec. 14, 2010]



Sec. 115.113  Passengers permitted.

    (a) The maximum number of passengers permitted must be not more than 
that allowed by the requirements of this section, except as authorized 
by the OCMI under paragraph (d) of this section.
    (b) The maximum number of passengers permitted on any vessel may be 
the greatest number permitted by the length of rail criterion, deck area 
criterion, or fixed seating criterion described in this paragraph or a 
combination of these criteria as allowed by paragraph (c) of this 
section.
    (1) Length of rail criterion. One passenger may be permitted for 
each 760 millimeters (30 inches) of rail space

[[Page 287]]

available to the passengers at the periphery of each deck. The following 
rail space may not be used in determining the maximum number of 
passengers permitted:
    (i) Rail space in congested areas unsafe for passengers, such as 
near anchor handling equipment or line handling gear, in the way of sail 
booms, running rigging, or paddle wheels, or along pulpits;
    (ii) Rail space on stairways; and
    (iii) Rail space where persons standing in the space would block the 
line of vision of the credentialed individual operating the vessel.
    (2) Deck area criterion. One passenger may be permitted for each 0.9 
square meters (10 square feet) of deck area available for the 
passengers' use. In computing such deck area, the areas occupied by the 
following must be excluded:
    (i) Areas for which the number of persons permitted is determined 
using the fixed seating criteria;
    (ii) Obstructions, including stairway and elevator enclosures, 
elevated stages, bars, and cashier stands, but not including slot 
machines, tables, or other room furnishings;
    (iii) Toilets and washrooms;
    (iv) Spaces occupied by and necessary for handling lifesaving 
equipment, anchor handling equipment or line handling gear, or in the 
way of sail booms or running rigging;
    (v) Spaces below deck that are unsuitable for passengers or that 
would not normally be used by passengers;
    (vi) Interior passageways less than 840 millimeters (34 inches) wide 
and passageways on open deck, less than 710 millimeters (28 inches) 
wide;
    (vii) Bow pulpits, swimming platforms and areas that do not have a 
solid deck, such as netting on multi-hull vessels;
    (viii) Deck areas in way of paddle wheels; and
    (ix) Aisle area provided in accordance with Sec. 116.820(d) of this 
chapter.
    (3) Fixed seating criterion. One passenger may be permitted for each 
455 millimeter (18 inches) of width of fixed seating provided by Sec. 
116.820 of this chapter. Each sleeping berth in overnight accommodation 
spaces shall be counted as only one seat.
    (c) Different passenger capacity criteria may be used on each deck 
of a vessel and added together to determine the total passenger capacity 
of that vessel. Where seats are provided on part of a deck and not on 
another, the number of passengers permitted on a vessel may be the sum 
of the number permitted by the seating criterion for the space having 
seats and the number permitted by the deck area criterion for the space 
having no seats. The length of rail criterion may not be combined with 
either the deck area criterion or the fixed seating criterion when 
determining the maximum number of passengers permitted on an individual 
deck.
    (d) For a vessel operating on short runs on protected waters such as 
a ferry, the cognizant OCMI may give special consideration to increases 
in passenger allowances.

[CGD 85-080, 61 FR 892, Jan. 10, 1996, as amended by USCG-2006-24371, 74 
FR 11265, Mar. 16, 2009]



Sec. 115.114  Alternative requirements for a vessel operating as
other than a small passenger vessel.

    (a) When authorized by the cognizant OCMI by an endorsement of the 
vessel's Certificate of Inspection, a small passenger vessel carrying 
six or less passengers, or operating as a commercial fishing vessel or 
other uninspected vessel, or carrying less than twelve passengers and 
operating as a recreational vessel, need not meet requirements of:
    (1) Subparts C, D, and E, of part 117 of this chapter if the vessel 
is in satisfactory compliance with the lifesaving equipment regulations 
for an uninspected vessel or recreational vessel in similar service;
    (2) Subpart C of part 116 of this chapter and subchapter S of this 
chapter if the vessel is in satisfactory compliance with applicable 
regulations for an uninspected vessel or recreational vessel in a 
similar service or if the owner of the vessel otherwise establishes to 
the satisfaction of the cognizant OCMI that the vessel is seaworthy for 
the intended service; and
    (3) Sections 121.404, 121.408, and 121.410 of this subchapter 
providing the vessel is in satisfactory compliance

[[Page 288]]

with any navigational equipment requirements for an uninspected or 
recreational vessel in a similar service.
    (b) A vessel operating under the alternative regulations of 
paragraph (a) of this section must:
    (1) Not alter the arrangement of the vessel nor remove any equipment 
required by the certificate for the intended operation, without the 
consent of the cognizant OCMI;
    (2) Comply with minimum manning specified on the Certificate of 
Inspection, which may include reduced manning depending on the number of 
passengers and operation of the vessel;
    (3) When carrying from one to six passengers except for a vessel 
being operated as a recreational vessel, make the announcement required 
by Sec. 122.506(a) of this subchapter before getting underway; and
    (4) If a vessel of more than 15 gross tons, not carry freight for 
hire.
    (c) The endorsement issued under paragraph (a) of this section must 
indicate the route, maximum number of passengers, and the manning 
required to operate under the provisions of this section.

[CGD 85-080, 61 FR 892, Jan. 10, 1996, as amended by USCG-2014-0688, 79 
FR 58283, Sept. 29, 2014]



Sec. 115.120  Certificate of Inspection amendment.

    (a) An amended Certificate of Inspection may be issued at any time 
by any OCMI. The amended Certificate of Inspection replaces the 
original, but the expiration date remains the same as that of the 
original. An amended Certificate of Inspection may be issued to 
authorize and record a change in the dimensions, gross tonnage, owner, 
managing operator, manning, persons permitted, route permitted, 
conditions of operations, or equipment of a vessel, from that specified 
in the current Certificate of Inspection.
    (b) A request for an amended Certificate of Inspection must be made 
to the cognizant OCMI by the owner or managing operator of the vessel at 
any time there is a change in the character of a vessel or in its route, 
equipment, ownership, operation, or other similar factors specified in 
its current Certificate of Inspection.
    (c) The OCMI may require an inspection prior to the issuance of an 
amended Certificate of Inspection.



               Subpart B_Special Permits and Certificates



Sec. 115.202  Permit to proceed.

    (a) When a vessel is not in compliance with its Certificate of 
Inspection or fails to comply with a regulation of this subchapter, the 
cognizant OCMI may permit the vessel to proceed to another port for 
repair if, in the judgment of the OCMI, the trip can be completed 
safely, even if the Certificate of Inspection of the vessel has expired 
or is about to expire.
    (b) Form CG-948, ``Permit to Proceed to another Port for Repairs,'' 
may be issued by the cognizant OCMI to the owner, managing operator, or 
the master of the vessel stating the conditions under which the vessel 
may proceed to another port. The permit may be issued only upon the 
written application of the owner, managing operator, or master, and 
after the vessel's Certificate of Inspection is turned over to the OCMI.
    (c) A vessel may not carry passengers when operating in accordance 
with a permit to proceed, unless the cognizant OCMI determines that it 
is safe to do so.



Sec. 115.204  Permit to carry excursion party.

    (a) The cognizant OCMI may permit a vessel to engage in a temporary 
excursion operation with a greater number of persons or on a more 
extended route, or both, than permitted by its Certificate of Inspection 
when, in the opinion of the OCMI, the operation can be undertaken 
safely.
    (b) Upon the written application of the owner or managing operator 
of the vessel, the cognizant OCMI may issue a Form CG-949, ``Permit to 
Carry Excursion Party.'' to indicate his or her permission to carry an 
excursion party. The OCMI will indicate on the permit the conditions 
under which it is issued, the number of persons the vessel may carry, 
the crew required, any additional lifesaving or safety equipment 
required, the route for which the permit is granted, and the dates on 
which the permit is valid.

[[Page 289]]

    (c) The number of passengers normally permitted on an excursion 
vessel is governed by Sec. 115.113 of this part.
    (d) The OCMI will not normally waive applicable minimum safety 
standards when issuing an excursion permit. In particular, a vessel that 
is being issued an excursion permit will normally be required to meet 
the minimum stability, survival craft, life jacket, fire safety, and 
manning standards applicable to a vessel in the service for which the 
excursion permit is requested
    (e) The permit acts as a temporary, limited duration supplement to 
the vessel's Certificate of Inspection and must be carried with the 
Certificate of Inspection. A vessel operating under a permit to carry an 
excursion party must be in full compliance with the terms of its 
Certificate of Inspection as supplemented by the permit.
    (f) The OCMI may require an inspection prior to the issuance of a 
permit to carry an excursion party.



    Subpart C_Posting of Certificates, Permits, and Stability Letters



Sec. 115.302  Certificates and permits.

    The Certificate of Inspection and any SOLAS Certificates must be 
posted under glass or other suitable transparent material, such that all 
pages are visible, in a conspicuous place on the vessel where 
observation by passengers is likely. If posting is impracticable, such 
as on open boats, the certificates must be kept on board in a 
weathertight container readily available for use by the crew and for 
display to passengers and others on request.



Sec. 115.306  Stability letter.

    When, in accordance with Sec. 170.120 in subchapter S of this 
chapter, a vessel must be provided with a stability letter, the 
stability letter must be posted under glass or other suitable 
transparent material, such that all pages are visible, at the operating 
station of the vessel. If posting is impracticable, the stability letter 
must be kept on board in a weathertight container readily available for 
use by the crew and for display to passengers and others on request.



Sec. 115.310  Certification expiration date stickers.

    (a) A Certification Expiration Date Sticker indicates the date upon 
which the vessel's Certificate of Inspection expires and is provided by 
the cognizant OCMI in the number required, upon issuance or renewal of 
the Certificate of Inspection.
    (b) A vessel that is issued a Certificate of Inspection under the 
provisions of this subchapter must not be operated without a valid 
Certification Expiration Date Sticker affixed to the vessel on a place 
that is:
    (1) A glass or other smooth surface from which the sticker may be 
removed without damage to the vessel;
    (2) Readily visible to each passenger prior to boarding the vessel 
and to patrolling Coast Guard law enforcement personnel; and
    (3) Acceptable to the Coast Guard marine inspector.
    (c) The Coast Guard marine inspector may require the placement of 
more than one sticker in order to insure compliance with paragraph 
(b)(2) of this section.



                 Subpart D_Inspection for Certification



Sec. 115.400  General.

    (a) An inspection is required before the issuance of a Certificate 
of Inspection. Such an inspection for certification is not made until 
after receipt of the application for inspection required by Sec. 
115.105 of this part.
    (b) Upon receipt of a written application for inspection, the 
cognizant OCMI assigns a marine inspector to inspect the vessel for 
compliance with this subchapter at a time and place mutually agreed upon 
by the OCMI and the owner, managing operator, or representative thereof.
    (c) The owner, managing operator, or a representative thereof shall 
be present during the inspection.



Sec. 115.402  Initial inspection for certification.

    (a) Before construction or conversion of a vessel intended for small 
passenger vessel service, the owner of the vessel

[[Page 290]]

shall submit plans, manuals, and calculations indicating the proposed

                Subpart F_Hull and Tailshaft Examinations



Sec. 115.600  Drydock examination, internal structural examination,
and underwater survey intervals.

    (a) The owner or managing operator shall make a vessel available for 
drydock examinations, internal structural examinations, and underwater 
surveys required by this section.
    (b) If your vessel is operated on international voyages subject to 
SOLAS requirements, it must undergo a drydock examination once every 12 
months unless it has been approved to undergo an underwater survey 
(UWILD) per Sec. 115.615 of this part. If the vessel becomes due for a 
drydock examination or an internal structural examination during the 
voyage, it may lawfully complete the voyage prior to the examination if 
it undergoes the required examination upon completion of the voyage to 
the United States but not later than 30 days after the examination is 
due. If the vessel is due for an examination within 15 days of sailing 
on an international voyage from a United States port, it must undergo 
the required examination before sailing.
    (c) If your vessel is operated on other than international voyages 
and does not meet the conditions in paragraph (d) of this section, it 
must undergo a drydock and internal structural examination as follows 
unless it has been approved to undergo an underwater survey (UWILD) per 
Sec. 115.615 of this part:
    (1) A vessel that is exposed to salt water more than three months in 
any 12 month period since the last examination must undergo a drydock 
examination and an internal structural examination at least once every 
two years; and
    (2) A vessel that is exposed to salt water not more than three 
months in any 12 month period since the last examination must undergo a 
drydock examination and an internal structural examination at least once 
every five years.
    (d) Whenever damage or deterioration to hull plating or structural 
members that may affect the seaworthiness of a vessel is discovered or 
suspected, the cognizant OCMI may conduct an

[[Page 292]]

internal structural examination in any affected space, including fuel 
tanks, and may require the vessel to be drydocked or taken out of 
service to assess the extent of the damage, and to effect permanent 
repairs. The OCMI may also decrease the drydock examination intervals to 
monitor the vessel's structural condition.
    (e) For a vessel that is eligible per Sec. 115.625 of this part and 
the owner opts for an alternate hull examination with the underwater 
survey portion conducted exclusively by divers, the vessel must undergo 
two alternate hull exams and two internal structural exams within any 
five-year period. If a vessel completes a satisfactory alternate hull 
exam, with the underwater survey portion conducted predominantly by an 
approved underwater remotely operated vehicle (ROV), the vessel must 
undergo one alternate hull and one internal structural exam, within any 
five-year period. The vessel may undergo a drydock exam to satisfy any 
of the required alternate hull exams.

Sec. 115.610  Scope of drydock and internal structural examinations.

    (a) A drydock examination conducted in compliance with Sec. 115.600 
of this part must be conducted while the vessel is hauled out of the 
water or placed in a drydock or slipway. During the examination all 
accessible parts of the vessel's underwater body and all through hull 
fittings, including the hull plating, appendages, propellers, shafts, 
bearings, rudders, sea chests, sea valves, and sea strainers shall be 
made available for examination. Sea chests, sea valves, and sea 
strainers must be opened for examination. The accuracy of draft or 
loading marks, if required by Sec. 122.602 of this subpart, must be 
verified if not already verified at construction or a previous drydock 
examination.
    (b) An internal structural examination conducted in compliance with 
Sec. 115.600 of this part may be conducted while the vessel is afloat 
or out of the water and consists of a complete examination of the 
vessel's main strength members, including the major internal framing, 
the hull plating, voids, and ballast, cargo, and fuel oil tanks. Where 
the internal framing or plating of the vessel is concealed, sections of 
the lining, ceiling or insulation may be removed or the parts otherwise 
probed or exposed so that the inspector may be satisfied as to the 
condition of the hull structure. Fuel oil tanks need not be cleaned out 
and internally examined if the marine inspector is able to determine by 
external examination that the general condition of the tanks is 
satisfactory.

Sec. 115.620  Description of the Alternative Hull Examination 
(AHE) Program for certain passenger vessels.

    The Alternative Hull Examination (AHE) Program provides you with an 
alternative to a drydock examination by allowing your vessel's hull to 
be examined while it remains afloat. If completed using only divers, 
this program has four steps: the application process, the preliminary 
examination, the pre-survey meeting, and the hull examination. If the 
vessel is already participating in the program or if a remotely operated 
vehicle (ROV) is used during the program, the preliminary exam step may 
be omitted. Once you complete these steps, the Officer in Charge, Marine 
Inspection (OCMI), will evaluate the results and accept the examination 
as a credit hull exam if the vessel is in satisfactory condition. If 
only divers are used for the underwater survey portion of the 
examination process, you may receive credit for a period of time such 
that subsequent AHEs would be conducted at intervals of twice in every 
five years, with no more than three years between any two AHEs. The OCMI 
may waive an underwater survey in accordance with Sec. 115.655(d) 
provided that the interval does not exceed five years between any two 
underwater surveys. If an underwater ROV is used as the predominate 
method to examine the vessel's underwater hull plating, you may receive 
credit up to five years. At the end of this period, you may apply for 
further participation under the AHE Program.

    Note to Sec. 115.620: The expected hull coverage when using an ROV 
must be at least 80 percent.

Sec. 115.625  Eligibility requirements for the Alternative
Hull Examination (AHE) Program for certain passenger vessels.

    (a) Your vessel may be eligible for the AHE Program if--
    (1) It is constructed of steel or aluminum;
    (2) It has an effective hull protection system;
    (3) It has operated exclusively in fresh water since its last 
drydock examination;
    (4) It operates in rivers or protected lakes; and
    (5) It operates exclusively in shallow water or within 0.5 nautical 
miles from shore.
    (b) In addition to the requirements in paragraph (a) of this 
section, the Officer in Charge, Marine Inspection (OCMI) will evaluate 
the following information when determining your vessel's eligibility for 
the AHE Program:
    (1) The overall condition of the vessel, based on its inspection 
history;
    (2) The vessel's history of hull casualties and hull-related 
deficiencies; and
    (3) The AHE Program application, as described in Sec. 115.630 of 
this part.
    (c) When reviewing a vessel's eligibility for the AHE program, the 
OCMI may modify the standards given by paragraph (a)(5) of this section 
where it is considered safe and reasonable to do so. In making this 
determination, the OCMI will consider the vessel's overall condition, 
its history of safe operation, and any other factors that serve to 
mitigate overall safety risks.

Sec. 115.630  The Alternative Hull Examination (AHE) Program application.

    If your vessel meets the eligibility criteria in Sec. 115.625 of 
this part, you may apply to the AHE Program. You must submit an 
application at least 90 days before the requested hull examination date 
to the Officer in Charge, Marine Inspection (OCMI) who will oversee the 
survey. The application must include--
    (a) The proposed time and place for conducting the hull examination;
    (b) The name of the participating diving contractor and underwater 
remotely operated vehicle (ROV) company which must be accepted by the 
OCMI under Sec. 115.650;
    (c) The name and qualifications of the third party examiner. This 
person must be familiar with the inspection procedures and his or her 
responsibilities under this program. The OCMI has the discretionary 
authority to accept or deny use of a particular third party examiner 
using the criteria established in 46 CFR 114.400;
    (d) A signed statement from your vessel's master, chief engineer, or 
the person in charge describing the vessel's overall condition, level of 
maintenance, known or suspected damage, underwater body cleanliness (if 
known), and the anticipated draft of the vessel at the time of the 
examination;
    (e) Plans or drawings that illustrate the external details of the 
hull below the sheer strake;
    (f) A detailed plan for conducting the hull examination in 
accordance with Sec. Sec. 115.645 and 115.650 of this part, which must

Sec. 115.635  Preliminary examination requirements.

    (a) If you exclusively use divers to examine the underwater hull 
plating, you must arrange to have a preliminary examination conducted by 
a third party examiner, with the assistance of qualified divers. The 
purpose of the preliminary examination is to assess the overall 
condition of the vessel's hull and identify any specific concerns to be 
addressed during the underwater hull examination.
    (b) If you use an underwater ROV as the predominate means to examine 
your vessel's hull plating, a preliminary examination and the 
participation of a third party examiner will not be necessary.
    (c) The preliminary examination is required only upon the vessel's 
entry or review into the AHE program.

[USCG-2000-6858, 67 FR 21081, Apr. 29, 2002]



Sec. 115.640  Pre-Survey meeting.

    (a) You must conduct a pre-survey meeting to discuss the details of 
the AHE procedure with the Officer in Charge, Marine Inspection (OCMI). 
If you exclusively use divers to examine the underwater hull plating, 
the third party examiner must attend the meeting and you must present 
the results of the preliminary examination. If you use an underwater 
remotely operated vehicle (ROV) as the predominate means to examine the 
vessel's hull plating, then a representative of the ROV operating 
company must attend the pre-survey meeting and address the underwater 
ROV's capabilities and limitations related to your vessel's hull design 
and configuration.
    (b) A vessel owner, operator, or designated agent must request this 
meeting in writing at least 30 days in advance of the examination date.
    (c) The pre-survey meeting may be conducted by teleconference, if 
agreed to in advance by the OCMI.

Sec. 115.645  Alternative Hull Examination (AHE) Procedure.

    (a) To complete the underwater survey you must--
    (1) Perform a general examination of the underwater hull plating and 
a detailed examination of all hull welds, propellers, tailshafts, 
rudders, and other hull appurtenances;
    (2) Examine all sea chests;

[[Page 295]]

    (3) Remove and inspect all sea valves in the presence of a marine 
inspector once every five years;
    (4) Remove all passengers from the vessel when the sea valves are 
being examined, if required by the Officer in Charge, Marine Inspection 
(OCMI);
    (5) Allow access to all internal areas of the hull for examination, 
except internal tanks that carry fuel (unless damage or deterioration is 
discovered or suspect), sewage, or potable water. Internal sewage and 
potable water tanks may be examined visually or by non-destructive 
testing to the satisfaction of the attending marine inspector; and
    (6) Meet the requirements in Sec. 115.650 of this part.
    (b) A marine inspector may examine any other areas deemed necessary 
by the OCMI.
    (c) If the AHE reveals significant deterioration or damage to the 
vessel's hull plating or structural members, the OCMI must be 
immediately notified. The OCMI may require the vessel be drydocked or 
otherwise taken out of service to further assess the extent of damage or 
to effect permanent repairs if the assessment or repairs cannot be 
completed to the satisfaction of the OCMI while the vessel is 
waterborne.

[USCG-2000-6858, 67 FR 21081, Apr. 29, 2002, as amended by USCG-2000-

Sec. 115.650  Alternative Hull Examination (AHE) Program options: 
Divers or underwater ROV.

    To complete your underwater survey, you may use divers or an 
underwater remotely operated vehicle (ROV).
    (a) If you use divers to conduct the underwater survey, you must--
    (1) Locate the vessel so the divers can work safely under the 
vessel's keel and around both sides. The water velocity must be safe for 
dive operations;
    (2) Provide permanent hull markings, a temporary grid system of 
wires or cables spaced not more than 10 feet apart and tagged at one-
foot intervals, or any other acoustic or electronic positioning system 
approved by the OCMI to identify the diver's location with respect to 
the hull, within one foot of accuracy;
    (3) Take ultrasonic thickness gaugings at a minimum of 5 points on 
each plate, evenly spaced;
    (4) Take hull plating thickness gaugings along transverse belts at 
the bow, stern, and midships, as a minimum. Plating thickness gaugings 
must also be taken along a longitudinal belt at the wind and water 
strake. Individual gaugings along the transverse and longitudinal belts 
must be spaced no more than 3 feet apart;
    (5) Ensure the third party examiner observes the entire underwater 
examination process;
    (6) Record the entire underwater survey with audio and video 
recording equipment and ensure that communications between divers and 
the third party examiner are recorded; and
    (7) Use appropriate equipment, such as a clear box, if underwater 
visibility is poor, to provide the camera with a clear view of the hull.
    (b) You may use an underwater ROV to conduct the underwater survey. 
The underwater ROV operating team, survey process and equipment, quality 
assurance methods, and the content and format of the survey report must 
be accepted by the Officer in Charge, Marine Inspection (OCMI) prior to 
conducting the survey. If you choose this option, you must--
    (1) Locate the vessel to ensure that the underwater ROV can operate 
effectively under the vessel's keel and around both sides;
    (2) Employ divers to examine any sections of the hull and 
appurtenances that the underwater ROV cannot access or is otherwise 
unable to evaluate; and
    (3) If the OCMI determines that the data obtained by the ROV, 
including non-destructive testing results, readability of the results, 
and positioning standards, will not integrate into the data obtained by 
the divers, then a third party examiner must be present during the 
divers portion of the examination.

[[Page 296]]



Sec. 115.655  Hull examination reports.

    (a) If you use only divers for the underwater survey portion of the 
Alternative Hull Examination (AHE), you must provide the Officer in 
Charge, Marine Inspection (OCMI), with a written hull examination 
report. This report must include thickness gauging results, bearing 
clearances, a copy of the audio and video recordings, and any other 
information that will help the OCMI evaluate your vessel for a credit 
hull exam. The third party examiner must sign the report and confirm the 
validity of its contents.
    (b) If you use an underwater remotely operated vehicle (ROV) as the 
predominate means to examine the vessel's underwater hull plating, you 
must provide the OCMI with a report in a format that is acceptable to 
the OCMI, per Sec. 115.650(b) of this part.
    (c) The OCMI will evaluate the hull examination report and grant a 
credit hull exam if satisfied with the condition of the vessel. If 
approved and you exclusively use divers to examine the hull plating, you 
may receive a credit hull exam to 36 months. (Underwater examinations 
are required twice every 5 years). If approved and you use an underwater 
ROV as the predominant means to examine the underwater hull plating, you 
may receive a credit hull exam up to 60 months (5 years).
    (d) At least 60 days prior to each scheduled underwater exam, the 
owner may request a waiver from the OCMI if:
    (1) A satisfactory exam has been completed within the last three 
years;
    (2) The conditions during the last exam allowed at least 80 percent 
of the bottom surface to be viewed and recorded; and
    (3) The results of the last exam indicated that an extended interval 
is safe and reasonable.

[USCG-2000-6858, 67 FR 21081, Apr. 29, 2002, as amended by USCG-2000-

Sec. 115.660  Continued participation in the Alternative Hull Examination (AHE) Program.

    (a) To continue to participate in the AHE Program, vessel operators 
must conduct an annual hull condition assessment. At a minimum, vessel 
operators must conduct an internal examination and take random hull 
gaugings internally during the hull condition assessment, unless waived 
by the Officer in Charge, Marine Inspection (OCMI). If the annual hull 
assessment reveals significant damage or corrosion, where temporary 
repairs have been made, or where other critical areas of concern have 
been identified, the OCMI may require an expanded examination to include 
an underwater hull examination using divers. If an underwater 
examination is required, the examination must focus on areas at higher 
risk of damage or corrosion and must include a representative sampling 
of hull gaugings.
    (b) If an underwater survey is required for the annual hull 
condition assessment, the OCMI may require the presence of a third party 
examiner and a written hull examination report must be submitted to the 
OCMI. This report must include thickness gauging results, a copy of the 
audio and video recordings and any other information that will help the 
OCMI evaluate your vessel for continued participation in the AHE 
program. The third party examiner must sign the report and confirm the 
validity of its contents.
    (c) You must submit your preventive maintenance reports or 
checklists on an annual basis to the OCMI. These reports or checklists 
must conform to the plans you submitted in your application under Sec. 
115.630 of this part, which the OCMI approved.
    (d) Prior to each scheduled annual hull condition assessment--
    (1) The owner may submit to the OCMI a plan for conducting the 
assessment, or a request for a waiver of this requirement, no fewer than 
30 days before the scheduled assessment; and
    (2) The OCMI may reduce the scope or extend the interval of the 
assessment if the operational, casualty, and deficiency history of the 
vessel, along with a recommendation of the vessel's master, indicates 
that it is warranted.

as far

[[Page 297]]

in advance as possible whenever a vessel is to be hauled out or placed 
in a drydock or slipway in compliance with Sec. 115.605 of this part or 
to undergo repairs or alterations affecting the safety of the vessel, 
together with the nature of any repairs or alterations contemplated. 
Hull repairs or alterations that affect the safety of the vessel include 
but are not limited to the replacement, repair, or refastening of 
planking, plating, or structural members, including the repair of cracks 
in the hull.

Sec. 116.415  Fire control boundaries.

    (a) Type and construction of fire control bulkheads and decks--(1) 
Major hull structure. The hull, structural bulkheads, columns and 
stanchions, superstructures, and deckhouses must be composed of steel or 
equivalent material.
    (2) Bulkheads and decks--Bulkheads and decks must be classed as A-
60, A-30, A-15, A-0, B-15, B-0, C, or C' based on the following:
    (i) A-Class bulkheads or decks must be composed of steel or 
equivalent material, suitably stiffened and made intact with the main 
structure of the vessel, such as the shell, structural bulkheads, and 
decks. They must be so constructed that, if subjected to the standard 
fire test, they are capable of preventing the passage of smoke and flame 
for 1 hour. In addition, they must be so insulated with approved 
structural insulation, bulkhead panels, or deck covering so that, if 
subjected to the standard fire test for the applicable time period 
listed below, the average temperature on the unexposed side does not 
rise more than 139 [deg]C (250 [deg]F) above the original temperature, 
nor does the temperature at any one point, including any joint, rise 
more than 181

[[Page 309]]

[deg]C (325 [deg]F) above the original temperature:

A-60 Class...............................  60 minutes
A-30 Class...............................  30 minutes
A-15 Class...............................  15 minutes
A-0 Class................................  0 minutes
 

    (ii) Penetrations in A-Class fire control boundaries for electrical 
cables, pipes, trunks, ducts, etc. must be constructed to prevent the 
passage of flame and smoke for one hour. In addition, the penetration 
must be designed or insulated so that it will withstand the same 
temperature rise limits as the boundary penetrated.
    (iii) B-Class bulkheads and decks must be constructed of 
noncombustible materials and made intact with the main structure of the 
vessel, such as shell, structural bulkheads, and decks, except that a B-
Class bulkhead need not extend above an approved continuous B-Class 
ceiling. They must be so constructed that, if subjected to the standard 
fire test, they are capable of preventing the passage of flame for 30 
minutes. In addition, their insulation value must be such that, if 
subjected to the standard fire test for the applicable time period 
listed below, the average temperature of the unexposed side does not 
rise more than 139 [deg]C (250 [deg]F) above the original temperature, 
nor does the temperature at any one point, including any joint, rise 
more than 225 [deg]C (405 [deg]F) above the original temperature:

B-15 Class...............................  15 minutes
B-0 Class................................  0 minutes
 

    (iv) Penetrations in B-Class fire control boundaries for electrical 
cables, pipes, trunks, ducts, etc. must be constructed to prevent the 
passage of flame for 30 minutes. In addition, the penetration must be 
designed or insulated so that it will withstand the same temperature 
rise limits as the boundary penetrated.
    (v) C-Class bulkheads and decks must be composed of noncombustible 
materials.
    (vi) C'-Class bulkheads and decks must be constructed of 
noncombustible materials and made intact with the main structure of the 
vessel, such as shell, structural bulkheads, and decks, except that a 
C'-Class bulkhead need not extend above a continuous B-Class or C'-Class 
ceiling. C'-Class bulkheads must be constructed to prevent the passage 
of smoke between adjacent areas. Penetrations in C'-Class boundaries for 
electrical cables, pipes, trunks, ducts, etc. must be constructed so as 
to preserve the smoke-tight integrity of the boundary.
    (vii) Any sheathing, furring, or holding pieces incidental to the 
securing of structural insulation must be approved noncombustible 
material.
    (b) Bulkhead requirements. Bulkheads between various spaces must 
meet the requirements of Table 116.415(b).

Sec. 116.438  Stairtowers, stairways, ladders, and elevators.

    (a) A vessel carrying more than 600 passengers or with overnight 
accommodations for more than 49 passengers must meet the requirements 
for stairways, ladders, and elevators in Sec. 72.05-20 of this chapter.
    (b) Materials. (1) Stairways, stairtowers, ladders, elevators, and 
landings must be designed with sufficient strength to sustain a load of 
4.8 kPa (100 pounds per square foot) with a safety factor of 4, based on 
ultimate strength of the material;
    (2) All stairways, ladders, elevators, and landings within machinery 
spaces and cargo holds must be composed of steel; and
    (3) All stringers, treads, and all platforms and landings of all 
stairways shall be composed of steel, and risers must be of approved 
incombustible material, except that:
    (i) Stairways, ladders, elevators, stringers, treads, platforms, and 
landings protected from potential fire exposure by being in either 
exterior locations or within protective enclosure bulkheads, decks and 
doors as described in the requirements of paragraph (j), may be 
constructed of approved incombustible material; and
    (ii) All stairways, ladders, elevators, stringers, treads, 
platforms, and landings subject to potential fire exposure and not 
within a protective enclosure must be composed of steel unless their 
failure will not hinder fire fighter access or debarkation.
    (c) A stairway or stairtower must be fitted with handrails on both 
sides at a vertical height above the tread at its nosing of between 840 
and 910 millimeters (33 and 36 inches). A stairway or stairtower of more 
than 1,680 millimeters (66 inches) in width must also be fitted with a 
center handrail.
    (d) A handrail fitted in a stairtower, stairway, landing, ladder, or 
elevator must be constructed of noncombustible material.
    (e) A stairway or stairtower must be clear of all obstructions other 
than handrails.
    (f) Curved, spiral, or winding stairways are permitted only with the 
specific approval of the Commandant.
    (g) Differences in the depth of tread or height of riser of stairs 
in different flights of stairs in a stairway or stairtower must be 
minimized. In an individual flight of stairs in a stairway or 
stairtower, the depth of the tread and the height of riser shall not 
have a variance exceeding 5 millimeters (0.19685 inches).
    (h) In a stairway or stairtower, the sum of the riser height and 
tread depth must be at least 432 millimeters (17 inches) and not more 
than 455 millimeters (18 inches). A stairway or stairtower having treads 
less than 254 millimeters (10 inches) in depth must have a nosing of 
12.7 millimeters (0.5 inches) in width.
    (i) Landings for stairways and stairtowers must meet the following 
requirements:
    (1) A clear landing having an area at least equal to the square of 
the tread width must be provided at the top and bottom of each stairway; 
and
    (2) Any interruption or change of direction in a stairway must be 
accomplished by means of an intermediate landing of a width and length 
at least equal to the tread width of the stairway.
    (j) A stairway or stairtower must not have an angle of inclination 
from the horizontal of more than 40 degrees. However, stairways 
accessing spaces visited solely by crew members must

[[Page 316]]

not have an angle of inclination from the horizontal of more than 50 
degrees. The Commanding Officer, Marine Safety Center may approve higher 
angles of inclination for spaces with severe space constraints.
    (k) Where a continuous vertical deck penetration for a stairway or 
elevator exceeds one deck, the integrity of all decks must be assured by 
enclosure bulkheads and decks meeting the requirements of Sec. Sec. 
116.415(b) and 116.415(c) of this part. Doors meeting the requirements 
of Sec. Sec. 116.435(b) and 116.435(c) of this part must be fitted in 
the enclosure at each deck serviced.
    (l) Where a vertical deck penetration for a stairway or elevator 
involves only one deck, the integrity of the deck must be assured as 
required by paragraph (k) of this section. Alternatively the integrity 
of the deck may be maintained at one level only by means of bulkheads of 
the same fire control boundary rating as the deck penetrated. A door 
meeting the requirements of Sec. Sec. 116.435(b) and 116.435(c) of this 
part must be fitted in the enclosure. In spaces containing a balcony, 
the integrity of the balcony deck in the way of stairways or elevators 
need not be assured. However, such stairways must not be considered to 
be a means of escape.
    (m) Arrangements. (1) Each main vertical zone with more than two 
deck levels, each having enclosed or partially enclosed accommodation 
spaces, other than washroom or toilet spaces and open decks, must be 
served by at least one stairtower, so that a person may escape from any 
accommodation space or any other space where persons may be normally 
quartered or employed, to all other decks having any such spaces within 
the same main vertical zone, without coming out of the stairtower 
enclosure. Where a stairtower is accessible from two main vertical 
zones, it may be considered as the required stairtower for both main 
vertical zones provided all boundaries of the stairtower meet main 
vertical zone boundary requirements contained in Sec. 116.415 of this 
part.
    (2) Each stairtower must give access to an embarkation station or an 
area of refuge identified in the emergency escape plan required by Sec. 
116.520.
    (3) Stairtowers must not give direct access to overnight 
accommodations or spaces of type 9, 10, 11, or 12.
    (4) A stairtower is not required to extend below deck to serve 
spaces in which a fire is likely to originate if one of the means of 
escape is:
    (i) A stairway that leads directly to a weather deck; or
    (ii) A stairway leading to a stairtower enclosure that includes self 
closing fire doors at both the top and bottom; or
    (iii) An alternative stairtower arrangement providing an equivalent 
level of safety is acceptable to the Commanding Officer, Marine Safety 
Center.
    (5) The Commanding Officer, Marine Safety Center may accept other 
means of escape in combination with a stairtower provided the exits open 
directly to weather or through a main vertical zone bulkhead.
    (6) For vessels in which a stairtower is not required, a stairway 
must provide a means of escape for each deck of the main vertical zone.
    (n) The minimum tread width of a stairway or stairtower must be 8.4 
millimeters (0.333 inches) for each person served, but must not be less 
than 910 millimeters (36 inches). However, in stairways accessing spaces 
utilized solely by crew members, the minimum tread width must be 8.4 
millimeters (0.333 inches) for each person served, but not less than 710 
millimeters (28 inches).
    (1) The minimum tread width of a stairway or stairtower must be 
determined for each deck considering only those persons on that deck, 
except as provided in paragraph (n)(3) of this section. Once a minimum 
tread width has been established at any deck, it must not be decreased 
in the direction of escape.
    (2) In determining the number of persons served, a space must be 
considered to contain at least the number of persons as follows:
    (i) Passenger overnight accommodation spaces: Designed capacity;
    (ii) Accommodation spaces having fixed seating for passengers: 
Maximum seating capacity;
    (iii) Public spaces, including spaces such as casinos, restaurants, 
club

[[Page 317]]

rooms, and cinemas, and public accommodation spaces as defined in Sec. 
114.400 of this subchapter, except overnight accommodation spaces: One 
person for each 0.9 square meters (10 square feet) of deck area. In 
computing such deck area, the following areas must be excluded:
    (A) Areas for which the number of persons permitted is determined 
using the fixed seating criterion;
    (B) Obstructions, including stairway and elevator enclosures, 
elevated stages, bars, and cashier stands, but not including slot 
machines, tables, or other room furnishings;
    (C) Toilets and washrooms;
    (D) Interior passageways less than 850 millimeters (34 inches) wide 
and passageways on open deck less than 710 millimeters (28 inches) wide;
    (E) Spaces necessary for handling lifesaving equipment, anchor 
handling equipment, or line handling gear, or in way of sail booms or 
running rigging; and
    (F) Bow pulpits, swimming platforms, and areas that do not have a 
solid deck, such as netting on multi hull vessels;
    (iv) Crew overnight accommodation spaces: Two-thirds designed 
capacity; and
    (v) Work spaces: Occupancy under normal operating conditions.
    (3) If a stairway forms part of a normal embarkation or debarkation 
route, or egress route to an area of refuge, the number of persons using 
the stairway for that purpose must be used in determining the minimum 
tread width. The Commanding Officer, Marine Safety Center, may approve a 
narrower stairway width if a narrower stairway will not unreasonably 
impede the flow of persons out of the space requiring egress or from an 
area of refuge to an embarkation station. Specific consideration can be 
given by the Marine Safety Center to the arrangement of landing area in 
excess of that required by paragraph (i) of this section when 
considering the approval of a narrower stairway width. However, the 
stairway width must be at least 910 millimeters (36 inches) unless the 
stairway is utilized solely by crew members, in which case the minimum 
tread width must be at least 710 millimeters (28 inches).
    (4) If more than one stairtower serves a main vertical zone, the 
number of persons in that main vertical zone may be distributed among 
the stairtowers.

requirements of this section.
    (b) Each level of a space containing a balcony must have two 
independent means of escape that meet the requirements of Sec. 116.500 
of this part.
    (c) For the purpose of main vertical zone bulkhead spacing 
requirements, the length of the space to which the balcony opens is 
considered to be increased by an amount equal to the gross area of the 
balcony divided by the average width of the space. If this equivalent 
main vertical zone length exceeds 40 meters (131 feet), the space must 
meet the requirements of paragraph (d) of this section. The actual 
length of the space may not exceed 40 meters (131 feet).
    (d) If the equivalent main vertical zone length under paragraph (c) 
of this section exceeds 40 meters (131 feet), both decks connected by 
the balcony must be protected with an automatic sprinkler system meeting 
NFPA 13.
    (e) If the unobstructed balcony opening area is less than 93 square 
meters (1,000 square feet), the opening must be protected in accordance 
with NFPA 13 or other standard specified by the Commandant. The 
horizontal projection area of stairs, escalators, statues, or other 
obstructions must be subtracted from the total balcony opening area for 
purposes of computation of unobstructed balcony opening area.

of atrium opening area.
    (b) The entire main vertical zone containing an atrium must be 
protected throughout with a smoke detection system of an approved type 
which is installed in accordance with Sec. 76.27 in subchapter H of 
this chapter. However, on vessels with no overnight passenger 
accommodations, smoke detectors may be omitted from the accommodation 
space containing the atrium.
    (c) The entire main vertical zone containing an atrium must be 
protected with an automatic sprinkler system meeting NFPA 13 
(incorporated by reference, see Sec. 114.600).
    (d) The atrium must be provided with a smoke extraction system that 
complies with either:
    (1) The smoke extraction system must be capable of exhausting the 
entire volume of the space within 10 minutes. The smoke extraction 
system must be capable of being activated by both the smoke detection 
system and by manual control, and designed with sufficient plenum air 
openings to prevent excessive negative air pressure in the atrium; or,
    (2) The smoke extraction system may be designed in accordance with 
the principles of NFPA 92B ``Smoke Management Systems in Malls, Atria,

    (6) Where subject to moisture, a storage cylinder must be installed 
to provide a space of at least 51 millimeters (2 inches) between the 
deck and the bottom of the storage cylinder.
    (7) A Halon 1301 storage cylinder must be stowed in an upright 
position unless otherwise listed by the independent laboratory. A carbon 
dioxide cylinder may be inclined not more than 30[deg] from the 
vertical, unless fitted with flexible or bent siphon tubes, in which 
case they may be inclined not more than 80[deg] from the vertical.
    (8) Where a check valve is not fitted on an independent storage 
cylinder discharge outlet, a plug or cap must be provided for closing 
the outlet resulting from storage cylinder removal.
    (9) Each storage cylinder must meet the requirements of Sec. 147.60 
in subchapter N of this chapter, or other standard specified by the 
Commandant.
    (10) A storage cylinder space must have doors that open outwards or 
be fitted with kickout panels installed in each door.
    (d) Piping. (1) A pipe, valve, or fitting of ferrous material must 
be protected inside and outside against corrosion unless otherwise 
approved by the Commandant. Aluminum or other low melting material must 
not be used for a component of a fixed gas fire extinguishing system 
except as specifically approved by the Commandant.
    (2) A distribution line must extend at least 51 millimeters (2 
inches) beyond the last orifice and be closed with a cap or plug.
    (3) Piping, valves, and fittings must be securely supported, and 
where necessary, protected against damage.
    (4) Drains and dirt traps must be fitted where necessary to prevent 
the accumulation of dirt or moisture and located in accessible

    (5) Piping must be used for no other purpose except that it may be 
incorporated with the fire detecting system.
    (6) Piping passing through accommodation spaces must not be fitted 
with drains or other openings within such spaces.
    (7) The distribution piping of a carbon dioxide fixed gas 
extinguishing system must be tested as required by this paragraph, upon 
completion of the piping installation, using only carbon dioxide, 
compressed air, or nitrogen gas.
    (i) Piping between a storage cylinder and a stop valve in the 
manifold must be subjected to a pressure of 6,894 kPa (1,000 psi), 
except as permitted in paragraph (d)(7)(iii) of this section. Without 
additional gas being introduced to the system, the pressure drop must 
not exceed 2,068 kPa (300 psi) after two minutes.

[[Page 340]]

    (ii) A distribution line to a space protected by the system must be 
subjected to a test similar to that described in paragraph (d)(7)(i) of 
this section, except that the pressure used must be 4,136 kPa (600 psi). 
For the purpose of this test, the distribution piping must be capped 
within the space protected at the first joint between the nozzles and 
the storage cylinders.
    (iii) A small independent system protecting a space such as a paint 
locker may be tested by blowing out the piping with air at a pressure of 
not less than 689 kPa (100 psi).
    (8) The distribution piping of a Halon 1301 fixed gas extinguishing 
system must be tested, as required by this paragraph, upon completion of 
the piping installation, using only carbon dioxide, compressed air, or 
nitrogen.
    (i) When pressurizing the piping, pressure must be increased in 
small increments. Each joint must be subjected to a soap bubble leak 
test, and all joints must be leak free.
    (ii) Piping between the storage cylinders and the manifold stop 
valve must be subjected to a leak test conducted as a pressure of 4,136 
kPa (600 psi). Without additional gas being added to the system, there 
must be no loss of pressure over a two minute period after thermal 
equilibrium is reached.
    (iii) Distribution piping between the manifold stop valve and the 
first nozzle in the system must be capped and pneumatically tested for a 
period of 10 minutes at 1,034 kPa (150 psi). At the end of 10 minutes, 
the pressure drop must not exceed 10% of the test pressure.
    (e) Pressure relief. When required by the cognizant OCMI, spaces 
that are protected by a fixed gas fire extinguishing system and that are 
relatively airtight, such as refrigeration spaces, paint lockers, etc., 
must be provided with suitable means for relieving excessive pressure 
within the space when the agent is released.
    (f) Specific requirements for carbon dioxide systems. A custom 
engineered fixed gas fire extinguishing system, which uses carbon 
dioxide as the extinguishing agent, must meet the requirements of this 
paragraph.
    (1) Piping, valves, and fittings must have a bursting pressure of 
not less than 41,360 kPa (6,000 psi). Piping, in nominal sizes of not 
more than 19 millimeters (0.75 inches), must be at least Schedule 40 
(standard weight), and in nominal sizes of over 19 millimeter (0.75 
inches), must be at least Schedule 80 (extra heavy).
    (2) A pressure relief valve or equivalent set to relieve at between 
16,550 and 19,300 kPa (2,400 and 2,800 psi) must be installed in the 
distribution manifold to protect the piping from overpressurization.
    (3) Nozzles must be approved by the Commandant.
    (4) When installed in a machinery space, paint locker, a space 
containing flammable liquid stores, or a space with a fuel tank, a fixed 
carbon dioxide system must meet the following requirements.
    (i) The quantity of carbon dioxide in kilograms (pounds) that the 
system must be capable of providing to a space must not be less than the 
gross volume of the space divided by the appropriate factor given in 
Table 118.410(f)(4)(i). If fuel can drain from a space being protected 
to an adjacent space or if the spaces are not entirely separate, the 
volume of both spaces must be used to determine the quantity of carbon 
dioxide required. The carbon dioxide must be arranged to discharge into 
both such spaces simultaneously.

    (iii) Distribution piping within a space must be proportioned from 
the distribution line to give proper supply to the outlets without 
throttling.
    (iv) The number, type, and location of discharge outlets must 
provide uniform distribution of carbon dioxide throughout a space.
    (v) The total area of all discharge outlets must not exceed 85 
percent nor be less than 35 percent of the nominal cylinder outlet area 
or the area of the supply pipe, whichever is smaller. The nominal 
cylinder outlet area in square millimeters (inches) is determined by 
multiplying the factor 0.015 (0.0022 if using square inches) by the 
total capacity in kilograms (pounds) of all carbon dioxide cylinders in 
the system, except in no case must the outlet area be of less than 71 
square millimeters (0.110 square inches).
    (vi) The discharge of at least 85 percent of the required amount of 
carbon dioxide must be completed within two minutes.
    (5) When installed in an enclosed ventilation system for rotating 
electrical propulsion equipment a fixed carbon dioxide system must meet 
the following requirements.
    (i) The quantity of carbon dioxide in kilograms (pounds) must be 
sufficient for initial and delayed discharges as required by this 
paragraph. The initial discharge must be equal to the gross volume of 
the system in cubic meters divided by 0.624 (10 if using pounds) for 
ventilation systems having a volume of less than 57 cubic meters (2,000 
cubic feet), or divided by 0.749 (12 if using pounds) for ventilation 
systems having a volume of at least 57 cubic meters (2,000 cubic feet). 
In addition, there must be sufficient carbon dioxide available to permit 
delayed discharges to maintain at least a 25 percent concentration until 
the equipment can be stopped. If the initial discharge achieves this 
concentration, a delayed discharge is not required.
    (ii) The piping sizes for the initial discharge must be in 
accordance with Table 118.410(f)(4)(ii) and the discharge of the 
required amount must be completed within two minutes.
    (iii) Piping for the delayed discharge must not be less than 12.7 
millimeters (0.5 inches) nominal pipe size, and need not meet specific 
requirement for discharge rate.
    (iv) Piping for the delayed discharge may be incorporated with the 
initial discharge piping.
    (6) When installed in a cargo space a fixed carbon dioxide system 
must meet the following requirements.
    (i) The number of kilograms (pounds) of carbon dioxide required for 
each space in cubic meters (feet) must be equal to the gross volume of 
the space in cubic meters (feet) divided by 1.88 (30 if using pounds).
    (ii) System piping must be of at least 19 millimeters (0.75 inches).
    (iii) No specific discharge rate is required.
    (7) A lockout valve must be provided on any carbon dioxide 
extinguishing system protecting a space over 6,000 cubic feet in volume 
and installed or altered after [July 9, 2013. ``Altered'' means modified 
or refurbished beyond the maintenance required by the manufacturer's 
design, installation, operation and maintenance manual.
    (8) The lockout valve must be a manually operated valve located in 
the discharge manifold prior to the stop valve or selector valves. When 
in the closed position, the lockout valve must provide complete 
isolation of the system from the protected space or spaces,

[[Page 342]]

making it impossible for carbon dioxide to discharge in the event of 
equipment failure during maintenance.
    (9) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (10) A valve is considered a lockout valve if it has a hasp or other 
means of attachment to which, or through which, a lock can be affixed, 
or it has a locking mechanism built into it.
    (11) The master or person-in-charge must ensure that the valve is 
locked open at all times, except while maintenance is being performed on 
the extinguishing system, when the valve must be locked in the closed 
position.
    (12) Lockout valves added to existing systems must be approved by 
the Commandant as part of the installed system.
    (g) Specific requirements for Halon 1301 systems. (1) A custom 
engineered fixed gas fire extinguishing system that uses Halon 1301, 
must comply with the applicable sections of UL 1058 ``Halogenated Agent 
Extinguishing System Units,'' and the requirements of this paragraph.
    (2) The Halon 1301 quantity and discharge requirements of UL 1058 
apply, with the exception that the Halon 1301 design concentration must 
be 6 percent at the lowest ambient temperature expected in the space. If 
the lowest temperature is not known, a temperature of -18 [deg]C (0 
[deg]F) must be assumed.
    (3) Each storage cylinder in a system must have the same pressure 
and volume.
    (4) Computer programs used in designing systems must be approved by 
an independent laboratory recognized by the Commandant.

    Note to Sec. 118.410(g): As of Jan. 1, 1994, the United States 
banned the production of Halon. The Environmental Protection Agency 
placed significant restrictions on the servicing and maintenance of 
systems containing Halon. Vessels operating on an international voyage, 
subject to SOLAS requirements, are prohibited from installing fixed gas 
fire extinguishing systems containing Halon.
    (h) Each carbon dioxide extinguishing system installed or altered 
after July 9, 2013, must have an approved odorizing unit to produce the 
scent of wintergreen, the detection of which will serve as an indication 
that carbon dioxide gas is present in a protected area and any other 
area into which the carbon dioxide may migrate. ``Altered'' means 
modified or refurbished beyond the maintenance required by the 
manufacturer's design, installation, operation and maintenance manual.

service for which it is intended. If your vessel passes the annual 
inspection, the marine inspector will endorse your current Certificate 
of Inspection.
    (3) If the annual inspection reveals deficiencies in your vessel's 
maintenance, you must make any or all repairs or improvements within the 
time period specified by the OCMI.
    (4) Nothing in this subpart limits the marine inspector from making 
such tests or inspections he or she deems necessary to be assured of the 
vessel's seaworthiness.
    (b) Periodic inspection. Your vessel must undergo a periodic 
inspection within 3 months before or after the second or third 
anniversary of the date of your vessel's Certificate of Inspection. This 
periodic inspection will take the place of an annual inspection.
    (1) You must contact the cognizant OCMI to schedule an inspection at 
a time and place which he or she approves. No written application is 
required.
    (2) The scope of the periodic inspection is the same as that for the 
inspection for certification, as specified in Sec. 126.430. The OCMI 
will insure that the vessel is in satisfactory condition and fit for the 
service for which it is intended. If your vessel passes the periodic 
inspection, the marine inspector will endorse your current Certificate 
of Inspection.
    (3) If the periodic inspection reveals deficiencies in your vessel's 
maintenance, you must make any or all repairs or improvements within the 
time period specified by the OCMI.
    (4) Nothing in this subpart limits the marine inspector from 
conducting such tests or inspections he or she deems necessary to be 
assured of the vessel's seaworthiness.



Sec. 126.520  Certificate of Inspection: Conditions of validity.

    To maintain a valid Certificate of Inspection, you must complete 
your annual and periodic inspections within the periods specified in 
Sec. 126.510 (a) and (b) and your Certificate of Inspection must be 
endorsed.



Sec. 126.530  Alternative annual inspection for offshore supply 
vessels less than 400 gross tons in foreign ports.

    (a) The owner, master or operator of an OSV of less than 400 gross 
tons may request authorization to conduct an alternative annual 
inspection in place of the annual inspection described in Sec. 
126.510(a) of this subpart. The request must go to the cognizant OCMI 
assigned responsibility for inspections in the country in which the 
vessel is operating and will be examined. To qualify for the alternative 
annual examination, the vessel must meet the following requirements:
    (1) The request must be in writing and be received by the OCMI not 
later than the anniversary date.
    (2) The vessel is likely to be continuously employed outside of the 
United States during the 3 months before and after each anniversary 
date.
    (b) In determining whether to authorize the alternative annual 
inspection, the OCMI considers the following:
    (1) Information contained in previous examination reports on 
inspection and drydock, including the recommendation of the then 
cognizant OCMI for participation in the alternative midperiod program 
and alternative annual examination.
    (2) The nature, number, and severity of marine casualties or 
accidents, as

[[Page 402]]

defined in Sec. 4.03-1 of this chapter, involving the vessel in the 3 
years preceding the request.
    (3) The nature, number, and gravity of any outstanding inspection 
requirements for the vessel.
    (4) The owner's or operator's history of compliance and cooperation 
in such alternative midperiod examinations and annual inspections, 
including:
    (i) The prompt correction of deficiencies.
    (ii) The reliability of previously submitted reports on such 
alternative midperiod examinations and annual inspections.
    (iii) The reliability of representations that the vessel would be, 
and was, employed outside of the United States during the 3 months 
before and after each anniversary date.
    (c) This OCMI provides the applicant with written authorization, if 
any, to proceed with the alternative annual inspection, including, when 
appropriate, special instructions.
    (d) The following conditions must be met for the alternative annual 
inspection to be accepted instead of the annual inspection required by 
Sec. 126.510 of this subpart:
    (1) The alternative annual inspection must occur within the 3 months 
before or after each anniversary date.
    (2) The alternative annual inspection must be of the scope detailed 
by Sec. 126.510(a) of this subchapter and must be conducted by the 
master, owner or operator of the vessel, or by a designated 
representative of the owner or operator.
    (3) Upon completion of the alternative annual inspection, the person 
or persons making the examination must prepare a comprehensive report 
describing the conditions found. This report must contain sufficient 
detail to let the OCMI determine whether the vessel is fit for the 
service and route specified on the Certificate of Inspection. This 
report must include all reports and receipts documenting the servicing 
of lifesaving equipment and any photographs or sketches necessary to 
clarify unusual circumstances. Each person preparing this report must 
sign it and certify that the information contained therein is complete 
and accurate.
    (4) Unless the master of the vessel participated in the alternative 
annual inspection and the preparation of the comprehensive report, the 
master will review the report for completeness and accuracy. The master 
must sign the report to indicate his or her review and validation and 
must forward it to the owner or operator of the vessel.
    (5) The owner or operator of a vessel examined under this section 
must review and submit the comprehensive report, required by paragraph 
(d)(3) of this section, to the OCMI. The report must reach the OCMI 
before the first day of the fifth month following the anniversary date. 
The forwarding letter or endorsement must be certified to be true and 
must contain the following information:
    (i) That the person or persons who made the alternative annual 
inspection acted on behalf of the vessel's owner or operator.
    (ii) That the report was reviewed by the owner or operator.
    (iii) That the discrepancies noted during the reinspection have been 
corrected, or will be within a stated time.
    (iv) That the owner or operator has sufficient personal knowledge of 
conditions aboard the vessel at the time of the reinspection, or has 
conducted inquires necessary to justify forming a belief that the report 
is complete and accurate.
    (e) The form of certification required under this section, for the 
alternative annual inspection, is as follows:

    I certify that to the best of my knowledge and belief the 
information contained in the report is complete and accurate.

    (f) Deficiencies and hazards discovered during the alternative 
annual inspection conducted pursuant to this section must be corrected 
or eliminated, if practical, before the examination report is submitted 
to the OCMI in accordance with paragraph (d)(5) of this section. 
Deficiencies and hazards that are not corrected or eliminated by the 
time the examination report is submitted must be listed in the report as 
``outstanding.'' Upon receipt of an examination report indicating 
outstanding deficiencies or hazards, the

[[Page 403]]

OCMI must inform the owner or operator in writing of the time period 
within which to correct or eliminate the deficiencies or hazards and the 
method for establishing that the corrections have been accomplished. 
Where a deficiency or hazard remains uncorrected or uneliminated after 
the expiration of the time specified for correction or elimination, the 
Officer in Charge, Marine Inspection must initiate appropriate 
enforcement measures.
    (g) Upon receipt of the report, the OCMI will evaluate it and 
determine the following:
    (1) Whether the cognizant OCMI accepts the alternative annual 
inspection instead of the annual inspection required by Sec. 126.510(a) 
of this subpart.
    (2) Whether the vessel is in satisfactory condition.
    (3) Whether the vessel continues to be reasonably fit for its 
intended service and route.
    (h) The OCMI may require further information necessary for the 
determinations required by this section. The OCMI will inform the owner 
or operator in writing of these determinations.
    (i) If the OCMI, in compliance with paragraph (g) of this section, 
does not accept the alternative annual inspection instead of the annual 
inspection required by Sec. 126.510(a) of this subpart, he or she will 
require reinspection of the vessel as soon as practicable. He or she 
will inform the vessel owner or operator in writing that the alternative 
examination is not acceptable and that a reinspection is necessary. The 
owner, master, or operator must make the vessel available for the 
reinspection at a time and place agreeable to this OCMI.
    (j) If the OCMI determines, in accordance with paragraph (g) of this 
section, that the alternative annual inspection is accepted in lieu of 
the annual inspection required by Sec. 126.510(a) of this subpart, the 
master must complete the applicable COI endorsement.

member not later than 2 weeks after the member first joins the vessel.
    (3) Each crew member must be instructed in the use of the vessel's 
lifesaving equipment and appliances and in survival at sea during 
alternate weeks, normally in the weeks when abandon-ship drills are not 
held. If individual instructional sessions cover different parts of the 
vessel's lifesaving system, they must cover each part of the vessel's 
lifesaving equipment and appliances each 2 months. Each member must be 
instructed in at least--
    (i) Operation and use of the vessel's inflatable liferafts;
    (ii) Problems of hypothermia, first aid for hypothermia, and other 
appropriate procedures; and
    (iii) Special procedures necessary for use of the vessel's 
lifesaving equipment and appliances in heavy weather.
    (4) Training in the use of davit-launched inflatable liferafts must 
take place at intervals of not more than 4 months on each vessel with 
such liferafts. Whenever practicable this must include the inflation and 
lowering of a liferaft. If this liferaft is a special one intended for 
training only, and is not part of the vessel's lifesaving system, it 
must be conspicuously so marked.
    (e) Dates when musters are held, details of abandon-ship drills, 
drills on other lifesaving equipment and appliances, and training aboard 
must be entered in the vessel's official logbook. Each logbook entry 
must include the following, as applicable:

Sec. 131.535  Firefighting training and drills.

    (a) A fire drill must be held on each vessel, normally on alternate 
weeks. It must not be held as part of the abandon-ship drill, nor 
immediately before or after the abandon-ship drill. If none can be held 
on schedule, because of bad weather or other unavoidable constraint, one 
must be held at the next opportunity.
    (b) Any crew member excused from a fire drill must participate in 
the next one, so that each member participates in at least one each 
month. Unless more than 25 percent of the members have participated in 
one on that particular vessel in the previous month, one must be held 
before the vessel leaves port if reasonable and practicable; but, unless 
the Commandant (CG-CVC) accepts alternative arrangements as at least 
equivalent, one must be held not later than 24 hours after the vessel 
leaves port in any event.
    (c) Each fire drill must include--

combustible liquids with a closed-cup flashpoint of 60 [deg]C or below 
must have:
    (1) An approved fixed-deck foam system arranged as follows:
    (i) If the flammable or combustible liquid tanks extend vertically 
to the weather deck, the foam system must comply with Sec. Sec. 34.20-
10 and 34.20-15 of this chapter, and protect the entire weather deck 
cargo area, including any tank openings, pumps, flanges, valves, vents, 
or loading manifolds. If petroleum products are carried, the minimum 
foam system discharge rate in liters per minute must be determined by 
multiplying the total cargo deck area by 6 lpm/m\2\. If polar solvent 
cargoes are carried, the minimum foam system discharge rate in liters 
per minute must be determined by multiplying the total cargo deck area 
by 10 lpm/m\2\, unless the approved foam system design manual specifies 
a different rate for the cargoes carried.
    (ii) If the flammable or combustible liquid tanks do not extend 
vertically to the weather deck, the foam system must be capable of 
protecting all weather deck areas within 10 feet (3 m) of any tank 
openings, pumps, flanges, valves, vents, or loading manifolds. The foam 
system must consist of at least one hoseline, and either fixed-foam 
monitors or fixed-foam nozzles that provide foam coverage of all 
required areas. The minimum foam system discharge rate must be 
calculated in accordance with paragraph (d)(1)(i) of this section, using 
the combined horizontal area of all parts of the deck requiring 
protection, instead of the total deck area.
    (iii) All foam liquid concentrate must be compatible with all 
flammable or combustible liquids carried.
    (iv) Sufficient foam liquid concentrate must be carried to allow 
operation of the system at its maximum discharge rate for at least 20 
minutes.
    (2) A fixed-gas fire-suppression system complying with Sec. 34.05-
5(a)(4) of this chapter, or other approved fire-extinguishing system 
determined acceptable by the Commandant, for the protection of any 
accessible below-deck cargo pump rooms or other spaces that have tank 
openings, pumps, flanges, valves, or loading manifolds associated with 
tanks carrying flammable or combustible liquids with a closed cup 
flashpoint of 60 [deg]C or below.

Sec. 136.115  Equivalents.

    (a) The Coast Guard may approve any arrangement, fitting, appliance, 
apparatus, equipment, calculation, information, or test that provides a 
level of safety equivalent to that established by any specific provision 
of this subchapter. Submit requests for approval to the Coast Guard via 
the cognizant OCMI. The Marine Safety Center may require engineering 
evaluations and tests to verify the equivalence.
    (b) The Coast Guard may accept compliance with the provisions of 
SOLAS applicable to the vessel's size and route (incorporated by 
reference, see Sec. 136.112), as an equivalent to specific requirements 
of this subchapter. Submit requests for a determination of equivalency 
for a particular vessel to the Coast Guard via the cognizant OCMI.
    (c) Alternative compliance arrangement provisions related to SMSs 
are contained in Sec. 138.225 of this subchapter.
    (d) Alternate compliance arrangements must be documented within the 
TSMS applicable to the vessel.

through 144 of this subchapter.
    (b) Regardless of the option chosen, the Coast Guard is responsible 
for issuing a towing vessel COI, and may board a vessel at any time to 
verify compliance and take appropriate action.
    (c) An owner or managing operator choosing the Coast Guard option 
may use a management system, vessel operations manual, towing vessel 
record (TVR), or logbook to meet this subchapter's recordkeeping 
requirements.

[[Page 477]]

    (d) When submitting an application for inspection, the owner or 
managing operator must specify on the application which option he or she 
chooses for each particular towing vessel. Owners or managing operators 
may choose different options for the individual vessels within their 
fleets.
    (e) Requests to change options during the period of validity of an 
existing COI must be accompanied by an application to the OCMI for a new 
COI. If the requirements for the new option are met, the OCMI will issue 
the vessel a new COI.



Sec. 136.172  Temporary compliance for existing towing vessels.

    An existing towing vessel subject to this subchapter will remain 
subject to Coast Guard regulations applicable to the vessel on July 19, 
2016 until either July 20, 2018 or the date the vessel obtains a COI, 
whichever date is earlier.



Sec. 136.175  Approved equipment.

    Where equipment in this subchapter is required to be of an approved 
type, such equipment requires the specific approval of the Coast Guard.

    (c) If necessary to prevent the delay of the vessel, the Coast Guard 
may issue a temporary COI to a towing vessel, pending the issuance and 
delivery of the permanent COI. The temporary COI must be carried in the 
same manner as the regular COI and is equivalent to the permanent COI 
that it represents.
    (d) A towing vessel on a foreign voyage between a port in the United 
States and a port in a foreign country whose COI expires during the 
voyage may lawfully complete the voyage without a valid COI, provided 
the voyage is completed within 30 days of expiration, and provided that 
the COI did not expire within 15 days of sailing on the foreign voyage 
from a U.S. port.



Sec. 136.202  Certificate of Inspection phase-in period.

    (a) All owners or managing operators of more than one existing 
towing vessel required to have a COI by this subchapter must ensure that 
each existing towing vessel under their ownership or control is issued a

the OCMI.



Sec. 136.210  Obtaining or renewing a COI.

    Owners and managing operators must submit Form CG-3752, 
``Application for

[[Page 478]]

Inspection of U.S. Vessel,'' to the cognizant OCMI where the inspection 
will take place. The owner or managing operator must submit the 
application at least 30 days before the vessel will undergo the initial 
inspection for certification. The owner or managing operator must 
schedule an inspection for this initial certification with the cognizant 
OCMI at least 3 months before the vessel is to undergo the inspection 
for certification.
    (a) In addition to Form CG-3752, the owner or managing operator must 
submit:
    (1) For initial certification:
    (i) Vessel particular information; and
    (ii) Number of persons in addition to the crew, if requested; or
    (2) For a renewal of certification:
    (i) Any changes to the information in paragraph (a)(1) of this 
section; and
    (ii) A description of any modifications to the vessel.
    (b) In addition to Form CG-3752 and the requirements of paragraph 
(a) of this section, the owner or managing operator of vessels utilizing 
the TSMS option must submit:
    (1) Objective evidence that the owner or managing operator and the 
vessel are in compliance with the TSMS requirements in part 138 of this 
subchapter; and
    (2) Objective evidence that the vessel's structure, stability, and 
essential systems comply with the applicable requirements of this 
subchapter for the intended route and service. This objective evidence 
may be in the form of a survey report issued by a TPO or another form 
acceptable to the Coast Guard.



Sec. 136.212  Inspection for certification.

    (a) Frequency of inspections. After a towing vessel receives its 
initial COI, the OCMI will inspect a towing vessel subject to this 
subchapter located in his or her jurisdiction at least once every 5 
years. The OCMI must ensure that every towing vessel is of a structure 
suitable for its intended route. If the OCMI deems it necessary, he or 
she may direct the vessel to get underway, and may adopt any other 
suitable means to test the towing vessel and its equipment.
    (b) Nature of inspection. The inspection will ensure that the vessel 
is in satisfactory condition and fit for the service for which it is 
intended, and that it complies with the applicable statutes and 
regulations for such vessels. The inspection will include inspections of 
the structure, pressure vessels and their appurtenances, piping, main 
and auxiliary machinery, electrical installations, lifesaving 
appliances, fire detecting and extinguishing equipment, pilot boarding 
equipment, and other equipment. The inspection will also determine that 
the vessel is in possession of any valid certificates or licenses issued 
by the Federal Communications Commission, if required. The inspection 
will also include an examination of the vessel's lights, means of making 
sound signals and distress signals, and pollution prevention systems and 
procedures.
    (c) Time of issuance of COI. The OCMI will issue a vessel a new COI 
after the vessel successfully completes the inspection for 
certification.



Sec. 136.215  Period of validity.

    (a) A COI for a towing vessel is valid for 5 years from the date of 
issue.
    (b) For a towing vessel utilizing the TSMS option, the COI is 
invalid upon the expiration or revocation of the owner or managing 
operator TSMS certificate or the ISM Code Certificate.
    (c) A COI may be suspended and withdrawn or revoked by the cognizant 
Officer in Charge, Marine Inspection at any time for noncompliance with 
the requirements of this subchapter.



Sec. 136.220  Posting.

    (a) The original COI must be framed under glass or other transparent 
material and posted in a conspicuous place onboard the towing vessel.
    (b) If posting is impracticable, the COI must be kept on board in a 
weathertight container and must be readily available.



Sec. 136.230  Routes permitted.

    (a) The area of operation for each towing vessel and any necessary 
operational limits are determined by the cognizant OCMI and recorded on 
the vessel's COI. Each area of operation, referred to as a route, is 
described on

[[Page 479]]

the COI under the major headings ``Oceans,'' ``Coastwise,'' ``Limited 
Coastwise,'' ``Great Lakes,'' ``Lakes, Bays, and Sounds,'' or 
``Rivers,'' as applicable. Additional limitations imposed or extensions 
granted are described by reference to bodies of waters, geographical 
points, distances from geographical points, distances from land, depths 
of channel, seasonal limitations, and similar factors.
    (b) Operation of a towing vessel on a route of lesser severity than 
those specifically described or designated on the COI is permitted, 
unless the route is expressly prohibited on the COI. The general order 
of decreasing severity of routes is: Oceans; coastwise; limited 
coastwise; Great Lakes; lakes, bays, and sounds; and rivers. The 
cognizant OCMI may prohibit a vessel from operating on a route of lesser 
severity than the primary route on which a vessel is authorized to 
operate, if local conditions necessitate such a restriction.
    (c) When designating a permitted route or imposing any operational 
limits on a towing vessel, the cognizant OCMI may consider:
    (1) The route-specific requirements of this subchapter;
    (2) The performance capabilities of the vessel based on design, 
scantlings, stability, subdivision, propulsion, speed, operating modes, 
maneuverability, and other characteristics;
    (3) The suitability of the vessel for nighttime operations and use 
in all weather conditions;
    (4) Vessel operations in globally remote areas or severe 
environments not covered by this subchapter. Such areas may include, but 
are not limited to, polar regions, remote islands, areas of extreme 
weather, or other remote areas where timely emergency assistance cannot 
be anticipated; and
    (5) The TSMS applicable to the vessel, if the vessel has one.



Sec. 136.235  Certificate of Inspection amendment.

    (a) An amended COI may be issued at any time by the cognizant OCMI. 
The amended COI replaces the original, but the expiration date remains 
the same as that of the original. An amended COI may be issued to 
authorize and record a change in the dimensions, gross tonnage, owner, 
managing operator, manning, persons permitted, route permitted, 
conditions of operations, or equipment of a towing vessel, from that 
specified in the current COI.
    (b) The owner or managing operator of the towing vessel must make a 
request for an amended COI to the cognizant OCMI any time there is a 
change in the character of the vessel or in its route, equipment, 
ownership, operation, or similar factors specified in its current COI. 
The OCMI may need to conduct an inspection before issuing an amended 
COI.
    (c) For those vessels selecting the TSMS option, the owner or 
managing operator of the towing vessel must provide to the OCMI 
objective evidence of compliance with the requirements in this 
subchapter prior to the issuance of an amended COI. The evidence must:
    (1) Be from a TPO and prepared in accordance with parts 138 and 139 
of this subchapter; and
    (2) Consider the change in the character of a vessel or in its 
route, equipment, ownership, operation, or similar factors specified in 
the vessel's current COI.



Sec. 136.240  Permit to proceed.

    Permission to proceed to another port for repairs (Form CG-948) may 
be required for a towing vessel that is no longer in compliance with its 
COI. This permission may be necessary in certain situations, including 
damage to the vessel, failure of an essential system, or failure to 
comply with a regulation, including failure to comply with the TSMS 
requirements, if appropriate.
    (a) What a vessel with a TSMS must do before proceeding to another 
port for repairs. A vessel with a TSMS may proceed to another port for 
repair, if:
    (1) In the judgment of the owner, managing operator, or master, the 
trip can be completed safely;
    (2) The TSMS addresses the condition of the vessel that has resulted 
in non-compliance and the necessary conditions under which the vessel 
may safely proceed to another port for repair;
    (3) The vessel proceeds as provided in the TSMS and does not tow 
while proceeding, unless the owner or managing

[[Page 480]]

operator determines that it is safe to do so; and
    (4) The owner or managing operator notifies the cognizant OCMI in 
whose zone the non-compliance occurred or is discovered, before the 
vessel proceeds. The owner or operator must also notify the cognizant 
OCMI in any other OCMI zones through which the vessel will transit.
    (b) What another vessel must do before proceeding to another port 
for repairs. If a vessel does not have a TSMS, or a vessel has one but 
it does not address the condition of the vessel that has resulted in 
non-compliance or the necessary conditions under which the vessel may 
safely proceed to another port for repair, the owner, managing operator, 
or master must request permission to proceed from the cognizant OCMI in 
whose zone the non-compliance occurs or is discovered. This permission 
operates as follows:
    (1) The request for permission to proceed may be made 
electronically, in writing, or orally. The cognizant OCMI may require a 
written description, a damage survey, or other documentation to assist 
in determining the nature and seriousness of the non-compliance.
    (2) The vessel will not engage in towing, unless the cognizant OCMI 
determines it is safe to do so.
    (3) The Coast Guard may issue the permit either on Form CG-948, 
``Permit to Proceed to Another Port for Repairs,'' or in letter form, 
and will state the conditions under which the vessel may proceed to 
another port for repair.
    (c) Inspection or examination. The cognizant OCMI may require an 
inspection of the vessel by a Coast Guard Marine Inspector or an 
examination by a surveyor from a TPO prior to the vessel proceeding.



Sec. 136.245  Permit to carry an excursion party or temporary
extension or alteration of route.

    (a) A towing vessel must obtain approval to engage in an excursion 
prior to carrying a greater number of persons than permitted by the COI, 
or to temporarily extend or alter its area of operation.
    (b) For a vessel utilizing the TSMS option, the vessel may engage in 
an excursion, if:
    (1) In the opinion of the owner, managing operator, or master the 
operation can be undertaken safely;
    (2) The TSMS addresses the temporary excursion operation 
contemplated; the necessary conditions under which the vessel may safely 
conduct the operation, including the number of persons the vessel may 
carry; the crew required; and any additional lifesaving or safety 
equipment required;
    (3) The vessel proceeds as provided in the TSMS; and
    (4) The owner, managing operator, or master notifies the cognizant 
OCMI at least 48 hours prior to the temporary excursion operation. The 
cognizant OCMI may require submission of pertinent provisions of the 
TSMS applicable to the vessel for review and onboard verification of 
compliance. If the cognizant OCMI has reasonable cause to believe that 
the TSMS applicable to the vessel is insufficient for the intended 
excursion, additional information may be requested and/or additional 
requirements may be imposed.
    (c) If the towing vessel is not under a TSMS, or the TSMS applicable 
to the vessel does not address the temporary excursion operation:
    (1) The owner or managing operator must submit an application to the 
cognizant OCMI. The application must state the intended route, number of 
passengers or guests, and any other conditions applicable to the 
excursion that exceed those specified in its COI.
    (2) The cognizant OCMI may issue the permit either on Form CG-949, 
``Permit To Carry Excursion Party,'' or in letter form. The cognizant 
OCMI will indicate on the permit the conditions under which it is 
issued, the number of persons the vessel may carry, the crew required, 
any additional lifesaving or safety equipment required, the route for 
which the permit is granted, and the dates on which the permit is valid. 
The application may be made electronically, in writing, or orally.
    (3) The vessel may not engage in towing during the excursion, unless 
the

[[Page 481]]

cognizant OCMI determines it is safe to do so.
    (d) The cognizant OCMI may require an inspection of the vessel by a 
Coast Guard Marine Inspector or an examination by a surveyor from a TPO 
prior to the vessel proceeding.

Safety Management System (TSMS) option.

    The owner or managing operator of a towing vessel choosing to use 
the TSMS option must implement an external or internal survey program 
for vessel compliance. The program for vessel compliance can be either:
    (a) An external survey program, in which the owner or managing 
operator

[[Page 482]]

would have a third-party organization (TPO) conduct either the surveys 
required by Sec. 137.205, the examinations required by Sec. 137.310, 
or both; or
    (b) An internal survey program, in which the owner or managing 
operator would conduct either the surveys required by Sec. 137.210, the 
examinations required by Sec. 137.315, or both, using internal 
resources or contracted surveyors. The internal survey program would be 
conducted with the oversight of a TPO.
    (c) Each program of either type must include:
    (1) Owner or managing operator policy regarding the surveying and 
examination of towing vessels;
    (2) Procedures for conducting towing vessel surveys and 
examinations, as described in this part;

applicable;
    (8) Signatures of surveyors;
    (9) A descriptive list of the items examined or witnessed during 
each survey;
    (10) A descriptive list of all non-conformities identified during 
each survey, including those that were corrected during the course of 
the survey;
    (11) A descriptive list of:
    (i) All non-conformities remaining at the end of each survey;
    (ii) The required corrective actions;
    (iii) The latest date of required corrective action; and
    (iv) A description of the means by which the corrective actions were 
verified;
    (12) A descriptive list of items that need to be repaired or 
replaced before the vessel continues service; and
    (13) A statement that the vessel complies with the applicable 
requirements of this subchapter and is fit for its route and service, 
subject to the correction of non-conformities.
    (b) The owner or managing operator must provide objective evidence 
of compliance with this part in accordance with the TSMS applicable to 
the vessel.



           Subpart B_Inspections and Surveys for Certification



Sec. 137.200  Documenting compliance for the Coast Guard inspection option.

    A towing vessel subject to this subchapter and choosing the Coast 
Guard inspection option, or required to have the Coast Guard inspection 
option, must undergo an annual inspection within 3 months before or 
after the COI anniversary date.
    (a) Owners and managing operators must contact the cognizant Officer 
in Charge, Marine Inspection (OCMI) to schedule an inspection at a time 
and place the OCMI approves. No written application is required.
    (b) Annual inspections will be similar to the inspection for 
certification but will cover less detail unless the marine inspector 
finds deficiencies or determines that a major change has occurred since 
the last inspection. If the marine inspector finds deficiencies or finds 
that a major change to the vessel has occurred, he or she will conduct a 
more detailed inspection to ensure that the vessel is in satisfactory 
condition and fit for the service for which it is intended. If the 
vessel passes the annual inspection, the Coast Guard will endorse the 
vessel's current Certificate of Inspection (COI).
    (c) If the annual inspection reveals the need, the owner or managing 
operator must make any or all repairs or

[[Page 483]]

improvements within the time period specified by the OCMI. The OCMI may 
use Form CG-835, ``Notice of Merchant Marine Inspection Requirements,'' 
to record deficiencies discovered during the inspection. The OCMI will 
then give a copy of the completed form to the master of the vessel.
    (d) Nothing in this subpart limits the marine inspector from 
conducting any tests or inspections he or she deems necessary to be 
assured of the vessel's seaworthiness or fitness for its route and 
service.



Sec. 137.202  Documenting compliance for the TSMS option.

    The owner or managing operator of a towing vessel that chooses the 
TSMS option for a towing vessel must document compliance with this 
subpart as follows:
    (a) Prior to obtaining the vessel's initial COI, the owner or 
managing operator must provide a report to the Coast Guard of a survey 
as described in Sec. 137.215 that demonstrates that the vessel complies 
the requirements of this part.
    (b) For the re-issuance of the vessel's COI, the owner or managing 
operator must:
    (1) Provide objective evidence of an external survey program as 
described in Sec. 137.205; or
    (2) Provide objective evidence of an internal survey program as 
described in Sec. 137.210.



Sec. 137.205  External survey program.

    (a) The owner or managing operator of a towing vessel that has 
selected the TSMS option and who has chosen to demonstrate compliance 
through an external survey program must:
    (1) Have the vessel surveyed annually by a surveyor from a TPO;
    (2) Ensure the survey is conducted in accordance with Sec. 137.215;
    (3) Ensure the survey is conducted within 3 months of the 
anniversary date of the COI;
    (4) Ensure the TSMS applicable to the vessel includes policies and 
procedures for complying with this section; and
    (5) Make the applicable sections of the TSMS available to the 
surveyor.
    (b) The TPO must issue a report that meets the requirements in Sec. 
137.135.



Sec. 137.210  Internal survey program.

    (a) The owner or managing operator of a towing vessel that has 
selected the TSMS option and who has chosen to demonstrate vessel 
compliance through an internal survey program must ensure that the TSMS 
applicable to the vessel includes:
