                               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, 2013), 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 accidentally dropped due to a printing or computer 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.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    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.

Sec.90.05-5  Specific application noted in text.

    (a) At the beginning of the various parts, subparts, and sections, a 
more specific application is generally given for the particular portion 
of the text involved. This application sets forth the types, sizes, or 
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.



Sec.90.05-7  Ocean or unlimited coastwise vessels on inland
and Great Lakes routes.

    (a) Vessels inspected and certificated for ocean or unlimited 
coastwise routes shall be considered suitable for navigation insofar as 
the provisions of this subchapter are concerned on any inland routes, 
including the Great Lakes.



Sec.90.05-10  Application to vessels on an international voyage.

    (a) Except for yachts and fishing vessels and as provided in 
paragraphs (b), (c), and (d) of this section, the regulations in this 
subchapter that apply to a vessel on an ``international voyage'' apply 
to a vessel that--
    (1) Is mechanically propelled and of at least 500 gross tons; and
    (2) Is engaged on a voyage--
    (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 
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 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--
    (1) Makes a single international voyage in exceptional 
circumstances; and
    (2) Meets safety requirements prescribed for the voyage by the 
Commandant.
    (d) The Commandant or his authorized representative may exempt any 
vessel from the construction requirements of this subchapter if the 
vessel does not proceed more than 20 nautical miles from the nearest 
land in the course of its voyage.

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 or more but of less than 500 gross tons, are 
subject to inspection under this subchapter. New offshore supply vessels 
as defined by Sec.90.10-40(c), are subject to inspection under 
subchapter L of this chapter.

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 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.

clearances.
    (6) The condition of the vessel, including the anticipated draft of 
the vessel at the time of the survey.
    (7) A description of the hull protection system.
    (e) Vessels otherwise qualifying under paragraph (d) of this 
section, that are 15 years of age or older, may be considered for 
continued participation in or entry into the underwater survey program 
on a case-by-case basis if--
    (1) Before the vessel's next scheduled drydocking, the owner or 
operator submits a request for participation or continued participation 
to Commandant (CG-CVC);
    (2) During the vessel's next drydocking after the request is 
submitted, no appreciable hull deterioration is indicated as a result of 
a complete set of hull gaugings; and

[[Page 42]]

    (3) The results of the hull gauging and the results of the Coast 
Guard drydock examination together with the recommendation of the 
Officer in Charge, Marine Inspection, are submitted to Commandant (CG-
CVC) for final approval.
    (f) Each vessel which has not met with the applicable examination 
schedules in paragraphs (a) through (e) of this section because it is on 
a voyage, must undergo the required examinations upon completion of the 
voyage.
    (g) The Commandant (CG-CVC) may authorize extensions to the 
examination intervals specified in paragraph (a) of this section.

meet the following requirements:
    (a) The field of vision from the navigation bridge, whether the 
vessel is in a laden or unladen condition, must be such that:
    (1) From the conning position, the view of the sea surface is not 
obscured forward of the bow by more than the lesser of two ship lengths 
or 500 meters (1,640 feet) from dead ahead to 10 degrees on either side 
of the vessel. Within this arc of visibility any blind sector caused by 
cargo, cargo gear, or other permanent obstruction must not exceed 5 
degrees.
    (2) From the conning position, the horizontal field of vision 
extends over an arc from at least 22.5 degrees abaft the beam on one 
side of the vessel, through dead ahead, to at least 22.5 degrees abaft 
the beam on the other side of the vessel. Blind sectors forward of the 
beam caused by cargo, cargo gear, or other permanent obstruction must 
not exceed 10 degrees each, nor total more than 20 degrees, including 
any blind sector within the arc of visibility described in paragraph 
(a)(1) of this section.
    (3) From each bridge wing, the field of vision extends over an arc 
from at least 45 degrees on the opposite bow, through dead ahead, to at 
least dead astern.
    (4) From the main steering position, the field of vision extends 
over and arc from dead ahead to at least 60 degrees on either side of 
the vessel.
    (5) From each bridge wing, the respective side of the vessel is 
visible forward and aft.
    (b) Windows fitted on the navigation bridge must be arranged so 
that:
    (1) Framing between windows is kept to a minimum and is not 
installed immediately in front of any work station.
    (2) Front windows are inclined from the vertical plane, top out, at 
an angle of not less than 10 degrees and not more than 25 degrees.
    (3) The height of the lower edge of the front windows is limited to 
prevent any obstruction of the foward view previously described in this 
section.
    (4) The height of the upper edge of the front windows allows a 
foward view of the horizon at the conning position, for a person with a 
height of eye of 1.8 meters (71 inches), when the vessel is at a forward 
pitch angle of 20 degrees.
    (c) Polarized or tinted windows must not be fitted.

Sec.92.07-5  Definitions.

    (a) Standard fire test. A ``standard fire test'' is one which 
develops in the test furnace a series of time temperature relationships 
as follows:

5 minutes--1,000 [deg]F.
10 minutes--1,300 [deg]F.
30 minutes--1,550 [deg]F.
60 minutes--1,700 [deg]F.

    (b) ``A'' Class divisions. Bulkheads or decks of the ``A'' Class 
shall be composed of steel or equivalent metal construction, suitably 
stiffened and made intact with the main structure of the vessel; such as 
shell, structural bulkheads, and decks. They shall be so constructed, 
that if subjected to the standard fire test, they would be capable of 
preventing the passage of flame and smoke for one hour.
    (c) ``B'' Class bulkheads. Bulkheads of the ``B'' Class shall be 
constructed with approved incombustible materials and made intact from 
deck to deck and to shell or other boundaries. They shall be so 
constructed that, if subjected to the standard fire test, they would be 
capable of preventing the passage of flame for one half hour.
    (d) ``C'' Class divisions. Bulkheads or decks of the ``C'' Class 
shall be constructed of approved incombustible materials, but need meet 
no requirements relative to the passage of flame.
    (e) Steel or other equivalent metal. Where the term ``steel or other 
equivalent metal'' is used in this subpart, it is intended to require a 
material which, by itself or due to insulation provided, has structural 
and integrity qualities equivalent to steel at the end of the applicable 
fire exposure.
    (f) Approved material. Where in this subpart approved materials are 
required, they refer to materials approved under the applicable subparts 
of Subchapter Q (Specifications) of this chapter, as follows:

                      Subpart 92.10_Means of Escape



Sec.92.10-1  Application.

    (a) The provisions of this subpart, with the exception of Sec.
92.10-90, shall apply to all vessels contracted for on or after November 
19, 1952. Vessels contracted for prior to November 19, 1952, shall meet 
the requirements of Sec.92.10-90.



Sec.92.10-5  Two means required.

    (a) There shall be at least two means of escape from all general 
areas accessible to the passengers, if carried, or where the crew may be 
quartered or normally employed. At least one of these two means of 
escape shall be independent of watertight doors.



Sec.92.10-10  Location.

    (a) The two means of escape shall be as remote as practicable so as 
to minimize the possibility of one incident blocking both escapes.



Sec.92.10-15  Vertical ladders not accepted.

    (a) Vertical ladders and deck scuttles shall not in general be 
considered satisfactory as one of the required means of escape. However, 
where it is demonstrated that the installation of a stairway would be 
impracticable, a vertical ladder may be used as the second means of 
escape.



Sec.92.10-20  No means for locking doors.

    (a) No means shall be provided for locking doors giving access to 
either of the two required means of escape, except that crash doors or 
locking devices, capable of being easily forced in an emergency, may be 
employed provided a permanent and conspicuous notice to this effect is 
attached to both sides of the door. This paragraph shall not apply to 
outside doors to deckhouses where such doors are locked by key only and 
such key is under the control of one of the vessel's officers.



Sec.92.10-25  Stairway size.

    (a) Stairways shall be of sufficient width having in mind the number 
of persons having access to such stairs for escape purposes.
    (b) Vessels contracted for on or after January 1, 1959, shall meet 
the requirements of this paragraph. Special consideration for relief may 
be given in the case of small vessels if it is shown to be unreasonable 
or impracticable to meet the requirements.
    (1) All interior stairways, other than those within the machinery 
spaces or cargo holds, shall have a minimum width of 28 inches. The 
angle of inclination with the horizontal of such stairways shall not 
exceed 50 degrees.



Sec.92.10-30  Dead end corridors.

    (a) Dead end corridors, or the equivalent, more than 40 feet in 
length shall not be permitted.



Sec.92.10-35  Public spaces.

    (a) In all cases, public spaces having a deck area of over 300 
square feet shall have at least two exits. Where practicable, these 
exits shall give egress to different corridors, rooms, or spaces to 
minimize the possibility of one incident blocking both exits.



Sec.92.10-40  Access to lifeboats.

    (a) The stairways, corridors, and doors shall be so arranged as to 
permit a ready and direct access to the various lifeboat embarkation 
areas.

[[Page 53]]



Sec.92.10-45  Weather deck communications.

    (a) Vertical communication shall be provided between the various 
weather decks by means of permanent inclined ladders.



Sec.92.10-90  Vessels contracted for prior to November 19, 1952.

    (a) Existing arrangements previously approved will be considered 
satisfactory so long as they are maintained in good condition to the 
satisfaction of the Officer in Charge, Marine Inspection. Minor repairs 
and alterations may be made to the same standards as the original 
design: Provided, That in no case will a greater departure from the

Sec.95.10-1  Application.

    (a) The provisions of this subpart, with the exception of Sec.
95.10-90, shall apply to all fire main installations contracted for on 
or after May 26, 1965. Installations contracted for prior to May 26, 
1965, shall meet the requirements of Sec.95.10-90.



Sec.95.10-5  Fire pumps.

    (a) Vessels shall be equipped with independently driven fire pumps 
in accordance with Table 95.10-5(a).

\1\ On vessels of 65 feet in length or less, \3/4\-inch hose of good
  commercial grade together with a commercial garden hose nozzle may be
  used. The pump may be hand operated and the length of hose shall be
  sufficient to assure coverage of all parts of the vessel.

[[Page 61]]

 
\2\ 75 feet of 1\1/2\-inch hose and \5/8\-inch nozzle may be used where
  specified by Sec. 95.10-10(b) for interior locations and 50 feet of
  1\1/2\-inch hose may be used in exterior locations on vessels in other
  than ocean or coastwise service.

    (b) On vessels of 1,000 gross tons and over 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, shall have a minimum capacity of at least two-
thirds of that required for an independent bilge pump. However, in no 
case shall the capacity of each fire pump be less than that otherwise 
required by this section.
    (c) Each pump shall 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 shall 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 shall 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 shall 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 shall 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 2 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 carbon dioxide 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 shall be as noted in Table 95.10-5(a).
    (b) In lieu of the 2\1/2\-inch hose and hydrants specified in Table 
95.10-5(a), on vessels over 1,500 gross tons, the hydrants in interior 
locations may have siamese connections for 1\1/2\-inch hose. In these 
cases the hose shall be 75 feet in length, and only one hose will be 
required at each fire station; however, if all such stations can be 
satisfactorily served with 50-foot lengths, 50-foot hose may be used.
    (c) On vessels of 500 gross tons and over 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 and over 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 shall be of sufficient number and so located that 
any part of the vessel, other than main machinery spaces, accessible to 
persons on

[[Page 62]]

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 shall be from a single length of hose. In main machinery 
spaces, all portions of such spaces shall be capable of being reached by 
at least 2 streams of water, each of which shall 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 shall be numbered as required by Sec.
97.37-15 of this subchapter.
    (e) All parts of the fire main located on exposed decks shall 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 shall be sealed open.
    (f) The outlet at the fire hydrant shall 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, and a hose rack or other device for stowing the hose.
    (h) Fire hose shall 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 shall not be used for any other purpose than fire 
extinguishing, drills, and testing.
    (m) Fire hydrants, nozzles, and other fittings shall 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 shall be brass, bronze, or 
other equivalent metal. Couplings shall either:
    (i) Use National Standard fire hose 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 shall 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.

       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 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

[[Page 65]]

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.

    (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 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

control releasing at least the required amount of carbon dioxide. These 
two controls shall be located in a box or other enclosure clearly 
identified for the particular space. Those systems installed without a 
stop valve shall be operated by one control releasing at least the 
required amount of carbon dioxide.
    (e) Where provisions are made for the simultaneous release of a 
given amount of carbon dioxide by operation of a remote control, 
provisions shall also be made for manual control at the cylinders. Where 
gas pressure from pilot cylinders is used as a means for releasing the 
remaining cylinders, not less

[[Page 66]]

than two pilot cylinders shall be used for systems consisting of more 
than two cylinders. Each of the pilot cylinders shall be capable of 
manual control at the cylinder, but the remaining cylinders need not be 
capable of individual manual control.
    (f) Systems of the type indicated in Sec.95.15-5(d), other than 
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.

such action.
    (e) In the event the master employs the discretionary provisions of 
this section after leaving port he shall cause appropriate entries to be 
made in the official log or equivalent thereof setting forth the time of 
uncovering, opening, closing or covering of the hatches or other 
openings to which this section applies and the circumstances warranting 
the action taken.
    (f) The discretionary provisions of this section shall not relieve 
the master of his responsibility for the safety of his vessel, her crew

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:

[[Page 140]]

    (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 
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 
30662, July 26, 1990; USCG 1999-4976, 65 FR 6504, Feb. 9, 2000]



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

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

[[Page 141]]

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 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.

                          Classified Locations



Sec.108.170  Definitions.

    (a) Classified locations are those in which flammable hydrocarbon 
gas or vapors, resulting from the drilling operations, may be present in 
quantities sufficient to produce an explosive or ignitable mixture. 
Location of these areas affect the design of the units' machinery, 
electrical, and ventilation systems. (See Notes 1 and 2).
    (b) For the purpose of this subpart ``semi-enclosed location'' means 
a location where natural conditions of ventilation are notably different 
from those on open decks due to the presence of structures such as 
roofs, windbreaks, or bulkheads.

    Notes: 1. Further requirements with respect to hazardous locations 
are contained in part 111, subpart 111.105, of this chapter.
    2. For specific requirements for machinery and electrical 
installations on mobile offshore drilling units see Subchapters ``F'' 
and ``J'' of this chapter.

 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

[[Page 201]]

``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 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.

[[Page 202]]

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.
    (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.

[[Page 203]]

    (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, 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).

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

[[Page 221]]

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.

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 of this chapter:
    (1) Propulsion circuits, Subpart 111.35.
    (2) Steering circuits, subchapter F of this chapter.

111.75.
    (5) Switchboard circuits, Subpart 111.30.
    (c) Fuses and circuitbreakers. If the allowable current-carrying 
capacity of the conductor does not correspond to a

[[Page 232]]

standard rating for fuses or circuitbreakers that meets Section 240.6 of 
NFPA NEC 2002 or IEC 60092-202 (both 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 circuitbreakers 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 NEC 2002 
or in IEC 60092-202.
    (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 
NEC 2002 or in IEC 60092-202.

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:

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 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).

[[Page 240]]



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 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.

   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.

[[Page 258]]



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 functions after the 
temporary emergency power source is disconnected.



                         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.

[CGD 74-125A, 47 FR 15267, Apr. 8, 1982, as amended by CGD 94-108, 61 FR 
28286, June 4, 1996; 61 FR 36787, July 12, 1996; USCG-2006-24797, 77 FR 
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
    (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 112.05-5(a) and have 
the capacity to supply all loads 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.

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

[[Page 296]]

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 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.

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,

[[Page 298]]

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.
    (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

                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 301]]

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

6858, 69 FR 47383, Aug. 5, 2004]



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 304]]

    (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.

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.

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.

    (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 [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

[[Page 318]]

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.

    (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:

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 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.

    (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 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;

[[Page 326]]

    (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.

shallow water where the vessel can not sink deep enough to submerge the 
topmost passenger deck or where survivors can wade ashore, the cognizant 
OCMI may waive a requirement for life floats, if the OCMI determines 
that it is safe to do so, taking into consideration the vessel's scope 
of operation, hazards of the route, and availability of assistance.
    (e) Each vessel operating with a set schedule on a specific route 
that maintains a 15 minute radio communications schedule with an 
operations base, or participates in a Vessel Traffic Service (VTS), may 
be granted a reduction in the survival craft requirements of this

safety exists.



Sec.117.210  Rescue boats.

    (a) Each vessel must carry at least one rescue boat unless the 
cognizant OCMI determines that:
    (1) The vessel is sufficiently maneuverable, arranged, and equipped 
to allow the crew to recover a helpless person from the water;
    (2) Recovery of a helpless person can be observed from the operating 
station; and
    (3) The vessel does not regularly engage in operations that restrict 
its maneuverability.
    (b) In general, a rescue boat must be a small, light-weight boat 
with built-in buoyancy and be capable of being readily launched and 
easily maneuvered. In addition, it must be of adequate proportion to 
permit taking an unconscious person on board without capsizing.
    (c) On a vessel of more than 19.8 meters (65 feet) in length 
operating on protected waters, a rescue boat approved under approval 
series 160.056 is acceptable in meeting the intent of this section. On a 
vessel of more than 19.8 meters operating on exposed or partially 
protected waters, a rescue boat approved under approval series 160.156 
is acceptable in meeting the intent of this section. On a vessel of not 
more than 19.8 meters (65 feet) in length, a required rescue boat must 
be acceptable to the cognizant OCMI.

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.
    (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

    (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.

[[Page 349]]

    (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 divided by 160 (10 if using pounds) for ventilation systems 
having a volume of less than 57 cubic meters (2,000 cubic feet), or 
divided by 192 (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.

[[Page 350]]

    (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 480 (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, 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.

preferably in a straight line, from the deck connection to the top of 
the tank. Such pipes must terminate on the weather deck and must be 
fitted with shutoff valves, watertight deck plates, or screw caps, 
suitably marked for identification. Diesel fill pipes and sounding pipes 
may terminate at the top of the tank.
    (f) Where a flexible fill pipe section is necessary, suitable 
flexible tubing or hose having high resistance to salt water, petroleum 
oils, heat and vibration, may be used. Such hose must overlap metallic 
pipe ends at least 1.5 times the pipe diameter and must be secured at 
each end by clamps. The flexible section must be accessible and as near 
the upper end of the fill pipe as practicable. When the flexible section 
is a nonconductor of electricity, the metallic sections of the fill pipe 
separated thereby must be joined by a conductor for protection against 
generation of a static charge when filling with fuel.

    Source: USCG 1999-4976, 65 FR 6505, Feb. 9, 2000, unless otherwise 
noted.



Sec.126.510  Annual and periodic inspections.

    (a) Annual inspection. Your vessel must undergo an annual inspection 
within 3 months before or after each anniversary date, except as 
required in paragraph (b) of this section.
    (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 annual inspection is the same as the inspection 
for certification as specified in Sec.126.430, 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

[[Page 405]]

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.

    (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 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.

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.

[[Page 406]]

    (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 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.

determinations required by this section. The

[[Page 407]]

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

         Subpart B_Portable and Semiportable Fire Extinguishers



Sec.132.210  Classification.

    (a) Each portable fire extinguisher and semiportable fire 
extinguisher is classified by a symbol combining letter and number. The 
letter indicates the type of fire that the unit should extinguish; the 
number indicates the relative size of the unit.
    (b) The types of fire are the following:
    (1) ``A''--fires in ordinary combustible materials, where the 
quenching and cooling effect of quantities of either water or solutions 
containing large percentages of water is essential.
    (2) ``B''--fires in flammable liquids, greases, and the like, where 
the blanketing effect of a smothering-agent is essential.
    (3) ``C''--fires in electrical equipment, where the use of 
nonconducting extinguishing-agent is essential.
    (c) The sizes of units run from ``I'' for the smallest to ``V'' for 
the largest. Sizes I and II are portable fire extinguishers; sizes III, 
IV, and V, which exceed 25 kilograms (55 pounds) in gross weight, are 
semiportable fire extinguishers and must be fitted with suitable hose 
and nozzle or other practicable means to cover any part of the space 
involved. Typical portable and semiportable fire extinguishers are set 
forth by Table 132.210 of this section.

unfavorable conditions of trim and with the OSV listed not less than 20 
degrees either way.
    (d) Each unguarded fall must not pass near any operating position of 
the winch, such as hand cranks, pay-out wheels, and brake levers.
    (e) Each winch drum must be arranged so the fall wire winds onto the

[[Page 462]]

drum in a level wrap. A multiple drum winch must be arranged so that the 
falls wind off at the same rate when lowering, and onto the drums at the 
same rate when hoisting.
    (f) Each fall, where exposed to damage or fouling, must have guards 
or equivalent protection. Each fall that leads along a deck must be 
covered with a guard that is not more than 300 millimeters (1 foot) 
above the deck.
    (g) The lowering speed for a fully loaded survival craft must be not 
less than that obtained from the following formula:
    (1) S=0.4+(0.02 H), where S is the speed of lowering in meters per 
second, and H is the height in meters from the davit head to the 
waterline at the lightest seagoing condition.
    (2) S=79+(1.2 H), where S is the speed of lowering in feet per 
minute, and H is the height in feet.

winch, must meet the requirements in part 129 of this chapter. If a 
survival craft is recovered by any means of power, including a portable 
power source, safety devices must be provided which automatically cut 
off the power before the davit arms or falls reach the stops in order to 
avoid overstressing the falls or davits, unless the motor is designed to 
prevent such overstressing.
    (k) Each launching appliance must be fitted with brakes that meet 
the following requirements:
    (1) The brakes must be capable of stopping the descent of the 
survival craft or rescue boat and holding it securely when loaded with 
its full complement of persons and equipment.
    (2) The brake pads must, where necessary, be protected from water 
and oil.

automatic disengaging apparatus approved under approval series 160.170 
instead of a lifeboat release mechanism. Each rescue boat must be able 
to be boarded and launched directly from the stowed position with the 
number of persons assigned to crew the rescue boat on board. If the 
rescue boat is also a lifeboat and the other lifeboats are boarded and 
launched from an embarkation deck, the arrangements must be such that 
the rescue boat can also be boarded and launched from the embarkation 
deck.
    (b) Each rescue boat must be capable of being launched with the OSV 
making headway of 5 knots in calm water. A painter may be used to meet 
this requirement.
    (c) Each rescue boat embarkation and launching arrangement must 
permit the rescue boat to be boarded and launched in the shortest 
possible time.
    (d) Rapid recovery of the rescue boat must be possible when loaded

Drilling Units'', assuming a steady wind speed of 100 knots for 
liftboats in unrestricted service, and 70 knots for liftboats in 
restricted service under normal operating conditions and 100 knots under 
severe storm conditions, as follows:
    (1) The main hull structure, legs, and supporting structure must 
comply with Section 3/4.3 of the Rules.
    (2) The calculations required by Section 3/4.3 of the Rules must 
assume the vessel to be in the most adverse loading conditions described 
by Sections 3/2.1 and 3/4.1 of the Rules.
    (3) Unless otherwise agreed upon by the Commandant (CG-ENG), the 
calculations on column-buckling required by Section 3/4.3 of the Rules, 
must employ an effective-length factor, ``K'', of not less than 2.0.
    (4) The calculations on single-rack jacking systems required by 
Sections 3/2.1 and 3/4.1 of the Rules must include an extra bending 
moment caused by the most adverse eccentric loading of the legs.
    (b) Standards of classification societies other than the ABS, and 
other established standards acceptable to the Commandant (CG-ENG), may 
be used.
    (c) Upon submittal of the plans required by Sec. Sec.127.110 and

and must comply with Sections 4/1.13.1 through 4/1.13.3 of the ABS's 
``Rules for Building and Classing Mobile Offshore Drilling Units'' as 
well as meet the applicable requirements of part 128 of this subchapter.
    (b) Each control system for a liftboat jacking system must be 
designed so that loss of power, loss of pressure in the hydraulic 
system, or low hydraulic-fluid level will activate a visible and audible 
alarm at the operating station and will not result in the liftboat's 
uncontrolled descent.



Sec.134.160  Freeboard markings.

    Freeboard markings required by Sec.174.260 of this subchapter must 
be both permanently scribed or embossed and painted white or yellow on a
