Offshore Supply Vessels

AGENCY: Coast Guard, DOT.

ACTION: Interim rule, with request for comments.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard is publishing, as an Interim Rule, a complete 
set of regulations (a whole new subchapter L) applicable to new 
offshore supply vessels (OSVs), including liftboats, and is providing 
the opportunity for additional public comment. These regulations are 
needed to implement statutory changes to the certification and 
inspection of conventional OSVs, and the certification and inspection 
of hitherto-uninspected liftboats. They contain many changes to current 
regulations and policy governing conventional OSVs, contain first-time 
regulations for liftboats, and make specific revisions to accommodate 
these vessels' unique characteristics, their methods of operation, and 
their types of service. These regulations are intended to eliminate the 
practice of circumventing inspection of certain categories of OSVs and 
to improve the level of safety of all OSVs, including liftboats, which 
will now be certificated and inspected.

DATES: This Interim Rule becomes effective on March 15, 1996; comments 
must be received on or before February 14, 1996. OSVs certificated 
before March 15, 1996, may either comply with these regulations in 
their entirety or continue to comply with, and to be certificated 
under, current regulations and policy. The Director of the Federal 
Register approves the incorporation by reference of certain 
publications listed in the regulations as of March 15, 1996.

ADDRESSES: Comments should be mailed to Executive Secretary, Marine 
Safety Council (G-LRA, 3406) [CGD 82-004 or CGD 86-074], U.S. Coast 
Guard, 2100 Second Street SW., Washington, DC 20593-0001. The comments 
and materials referred to in this notice will be available for 
examination and copying between 8 a.m. and 4 p.m., Monday through 
Friday, except holidays, at the Marine Safety Council, U.S. Coast 
Guard, Room 3406, 2100 Second Street SW., Washington, DC 20593-0001. 
Comments may also be hand-delivered.
    A Regulatory Assessment has been placed in the public docket for 
this rulemaking, and may be inspected and copied at the office of the 
Marine Safety Council, at the address listed above.

FOR FURTHER INFORMATION CONTACT:
James M. Magill, Office of Marine Safety, Security, and Environmental 
Protection (G-MOS-2), Room 1208c, U.S. Coast Guard Headquarters, 2100 
Second Street SW., Washington, DC 20593-0001, (202) 267-1181.

SUPPLEMENTARY INFORMATION: 

Request for Comments

    Because of the extended length of time from publication of the 
Notice of Proposed Rulemaking (NPRM) to publication of this interim 
rule, the Coast Guard encourages interested persons to participate in 
this rulemaking by submitting additional written data, views, or 
arguments. Persons submitting comments should include their names and 
addresses, identify this rulemaking (CGD 82-004 and CGD 86-074) and the 
specific section of the rule or related documents to which each comment 
applies; and give a reason for each comment. Please submit two copies 
of all comments and attachments in an unbound format, no larger than 
8\1/2\ by 11 inches, suitable for copying and electronic filing. 
Persons wanting acknowledgment of receipt of comments should enclose 
stamped, self-addressed postcards or envelopes.
    The Coast Guard recognizes that there are some differences in 
format and minor differences in terminology between this Interim Rule 
and the Supplementary Notice of Proposed Rulemaking for Small Passenger 
Vessel Inspection and Certification (CGD 85-080). The Coast Guard will 
be examining these differences with the object of attaining uniformity 
in format and terminology where identical requirements are intended. 
Differences in requirements may also be reconciled when the final rules 
for these two projects are published. Comments are invited identifying 
instances where apparently identical requirements are expressed 
differently, or where different requirements are imposed that may be 
candidates for uniform treatment.
    The Coast Guard will consider all comments received during the 
comment period. The rule may be changed in light of comments received.
    The Coast Guard plans no public hearing. Persons may request a 
public hearing by writing to the Marine Safety Council at the address 
under ADDRESSES. The request should include the reasons why a hearing 
would be beneficial. If it is determined that the opportunity for oral 
presentations will aid this rulemaking, the Coast Guard will hold a 
public hearing at a time and place announced by a later notice in the 
Federal Register.

    Drafting Information: Several offices at Coast Guard 
Headquarters participated in drafting this interim rule, but the 
principal persons involved in drafting this rule are James M. 
Magill, Project Manager, Office of Marine Safety, Security, and 
Environmental Protection, and Mr. Patrick J. Murray, Project 
Counsel, Office of the Chief Counsel.

Regulatory History

ANPRMs

    Two Advance Notices of Proposed Rulemaking (ANPRMs) have appeared 
in this rulemaking.
    On February 14, 1983, the Coast Guard published (48 FR 6636) an 
ANPRM, under CGD 82-004, to provide an early opportunity for public 
comment on a preliminary draft of a comprehensive set of requirements 
for inspection and certification applicable to new OSVs. Twenty-four 
comments were received, on various technical aspects of the proposal. 
Many of the recommendations from those comments were incorporated into 
the subsequent Notice of Proposed Rulemaking (NPRM) discussed below.
    On April 16, 1987, the Coast Guard published (52 FR 12439) a second 
ANPRM, under CGD 86-074, asking for specific information to help the 
Coast Guard in developing specialized regulations for self-elevating 
OSVs (liftboats). Fourteen comments were received. Many of the 
recommendations from those comments were incorporated into the 
subsequent NPRM discussed below.

NPRM

    On May 9, 1989, the Coast Guard published, under both CGD 82-004 
and 86-074, an NPRM (54 FR 20006). The comment period had originally 
been scheduled to end on September 6, 1989, but on August 31, 1989 (54 
FR 36040), it was extended until December 6, 1989. Included with the 
extension of the comment period was notice of a public hearing on the 
proposed rule, which hearing took place at New Orleans, Louisiana, on 
September 13, 1989. Twenty letters were received, containing one 
hundred and ninety-four comments on various technical aspects of the 
proposed rule. Many of the recommendations from those comments have 
been incorporated in this interim rule.

Discussion of This Interim Rule

    Conventional OSVs have traditionally provided a wide range of 
supply and support to offshore industries extracting oil and minerals. 
Once, these vessels operated almost exclusively in the Gulf of Mexico; 
now, they operate worldwide.
    Self-elevating OSVs, commonly known as liftboats, are more 
specialized in their service. These have built-in jacking-systems, 
which allow them to be ``jacked up'' above the ocean's surface and to 
become, in effect, stationary platforms for a temporary period. Once 
jacked up, these vessels render specific service, such as maintenance 
and construction, to adjacent offshore structures.

Conventional OSVs

    Conventional OSVs are propelled by motor, measure less than 500 
gross tons, and engage in short voyages. Until October 6, 1980, these 
vessels were--
    (a) Inspected by the Coast Guard as cargo and miscellaneous vessels 
under 46 CFR subchapter I, if of over 15 and under 500 gross tons and 
carrying freight for hire;
    (b) Inspected by the Coast Guard as small passenger-vessels under 
46 CFR subchapter T, if of less than 100 gross tons and carrying more 
than six passengers for hire; or
    (c) Not inspected by the Coast Guard, because they operated under 
``bareboat charters''.
    The vessels under subchapter I were known as ``supply boats.'' 
Typically, they were of steel construction, carried large amounts of 
deck cargo, and carried up to 16 persons in addition to the crew on 
domestic voyages as permitted by 46 U.S.C. 3304 (formerly 46 U.S.C. 
882).
    The vessels under subchapter T were known as ``crew boats.'' 
Typically, they were of aluminum or steel construction, were relatively 
swift, carried limited amounts of deck cargo, and carried a large 
number of passengers.
    Pub. L. 96-378, enacted on October 6, 1980, made important changes 
to how conventional OSVs were to be inspected by the Coast Guard. (In 
1983, the provisions of Pub. L. 96-378 were consolidated, without 
substantive change, and recodified in Title 46, U.S.C. Subtitle II. Its 
provisions are now contained principally in 46 U.S.C. 2101(19), 
2101(21)(C), 3301(3), 3302(g), 3306, 3307, 3501, and 8301.) Among the 
changes mandated by Pub. L. 96-378 were the following:
    (1) A controversial feature of the off-shore-support industry for 
many years had been its use of contractual arrangements, involving 
bareboat charters coupled with operating agreements, to circumvent a 
requirement for Certificates of Inspection from the Coast Guard. Pub. 
L. 96-378 eliminated this subterfuge by requiring all OSVs to be 
inspected.
    (2) Pub. L. 96-378 defined an OSV as any vessel that regularly 
carries goods, supplies, or equipment in support of exploration, 
exploitation, or production of offshore mineral or energy resources, is 
propelled by machinery other than steam (is a motor vessel), is not a 
small passenger-vessel regulated under 46 CFR subchapter T, and is of 
between 15 and 500 gross tons. (This definition has persisted into 46 
U.S.C. 2101(19).)
    (3) Pub. L. 96-378 categorized conventional OSVs as follows:
    (i) Pre-1979 OSVs--those (a) that were operating in support of the 
offshore industry on or before January 1, 1979, or (b) that were 
contracted for on or before that date and that entered into service 
before October 6, 1980.
    (ii) All other OSVs. Since 1980, over 350 conventional OSVs have 
been certificated under subchapter I or T.
    (4) Each conventional OSV, other than a pre-1979 OSV, is currently 
subject to inspection as follows:
    (i) A vessel of more than 15 gross tons but less than 100 gross 
tons is subject to Coast Guard inspection under subchapter I or T, 
depending on the owner's preference and the vessel's principal use.
    (ii) A vessel of 100 or more gross tons but less than 500 gross 
tons is subject to Coast Guard inspection under subchapter I.
    (5) Each pre-1979 OSV continues to be subject to inspection under 
subchapter I or T as applicable. On October 20, 1980, the Coast Guard 
published (45 FR 69242) a final rule requiring that pre-1979 OSVs be 
registered with Officers in Charge, Marine Inspection, on or before 
January 6, 1981, and that they be certificated not later than two years 
from the date of registration. These vessels are not subject to 
existing regulations on major changes of structure or major 
replacements of equipment unless compliance is necessary to remove 
especially hazardous conditions. The legislative history of Pub. L. 96-
378 states, in part, that OSVs should ``conform as closely as possible 
to inspection standards applied to new vessels''. However, Congress 
recognized that it would not be practicable to require major changes of 
structure or equipment on OSVs previously uninspected. Therefore, pre-
1979 OSVs are not subject to standards that require those major changes 
unless the Coast Guard determines that those changes are necessary to 
remove unreasonable risks to the vessels or their crews. Note that 46 
U.S.C. 2101 as amended now deems OSVs not to be tank vessels and, 
therefore, relieves them of having to meet requirements applicable to 
tank vessels for preventing oil pollution.

Liftboats

    The high rate of casualties experienced by self-elevating OSVs 
(liftboats) requires the development of specific regulations that 
address liftboats' design, stability, construction, and operations. The 
Coast Guard anticipates that promulgation and enforcement of the 
regulations in this Interim Rule will render new liftboats 
substantially safer than their predecessors.
    Again, on April 16, 1987, the Coast Guard published (52 FR 12439) 
an ANPRM, under CGD 86-074, asking for specific information to help the 
Coast Guard in developing specialized regulations for liftboats. As 
stated in this ANPRM, the need for regulations was based on the high 
incidence of casualties involving liftboats, and upon specific safety 
recommendations made by the National Transportation Safety Board (NTSB) 
in its review of those casualties.
    The Coast Guard conducted its review of the available history of 
casualties from 1980 to 1987 in advance of the 1987 ANPRM. The review 
showed that over 20% of the approximately 250 liftboats in the fleet 
had been involved in reported casualties, resulting in 10 deaths, 33 
serious injuries, constructive total loss of 13 vessels, and overall 
physical damage exceeding $20 million. Many of these casualties were 
directly attributable to inadequate design or improper operating 
procedures. The results of the 1987 review have been incorporated into 
the Regulatory Assessment referred to above under ADDRESSES. The review 
is also discussed, in more detail, in the following paragraphs.
    Until 1988, the Coast Guard regulated liftboats primarily under 46 
CFR subchapter C, which contains safety regulations for uninspected 
vessels. Virtually all liftboats were of under 300 gross tons and were, 
at that time, believed by the Coast Guard to provide mainly services 
under contract to the offshore industry; that is, these vessels and 
their crews were chartered by an operator to perform a particular 
function or task in support of offshore drilling or production. Since 
these vessels were of less than 300 gross tons and were not known or 
believed to be carrying goods and supplies in support of the offshore 
industry, they stood exempt from the 

[[Page 57632]]
requirements for inspection and certification under the general 
provisions of Title 46, U.S.C. (Chapter 33 or Subtitle II).
    The high incidence of casualties involving liftboats reflected in 
the 1987 review made it clear that the requirements in 46 CFR 
subchapter C were ineffective for promoting liftboats' safe operation. 
Further, the review showed that these vessels had been routinely 
carrying goods, supplies, equipment, and offshore workers to offshore 
structures, as well as performing their traditional function in support 
of construction and maintenance of offshore structures. Accordingly, 
the Coast Guard determined in 1988 to inspect liftboats as OSVs under 
46 U.S.C. 3301(3). On March 23, 1988, the Coast Guard published 
guidance for the inspection of liftboats as Change 1 (CH-1) to 
Navigation and Vessel Inspection Circular 8-81 (NVIC 8-81), ``Initial 
and Subsequent Inspection of Uncertificated Existing Offshore Supply 
Vessels under Public Law 96-378.'' On May 21, 1991, the Coast Guard 
published NVIC 8-91, interim guidance for applying the requirements of 
Subchapters I and T to existing liftboats, as appears more fully below. 
NVIC 8-91 cancelled NVIC 8-81 and its CH-1.

Specialized OSVs

    The 1987 ANPRM proposed that regulations for liftboats and other 
specialized OSVs be pursued in two distinct phases: Phase I to address 
liftboats; phase II to address specialized OSVs engaged in support of 
diving, of painting and sand-blasting, and so on. An analysis of the 
histories of casualties and of the operation of these specialized OSVs, 
conducted as a part of the effort to prepare the NPRM and this interim 
rule, shows that no additional regulations are necessary for these 
vessels as they are for liftboats. The requirements for new 
conventional OSVs in this rule will also apply to these specialized 
OSVs and should be sufficient to promote their safe operation. 
Consequently, the Coast Guard does not intend to act further on phase 
II of the 1987 ANPRM.

Existing OSVs

    The Coast Guard has historically tried to let owners and operators 
of existing vessels, first coming under inspection for certification, 
continue operation without being unduly penalized by newly promulgated 
regulations, provided their operations can be conducted safely. 
Existing conventional OSVs, including pre-1979 OSVs, had been inspected 
and certificated under guidance provided in NVIC 8-81, and by 
additional guidance for inspecting liftboats published as CH-1 to NVIC 
8-81. This additional guidance was developed to address the hazards 
contributing to the high number of liftboat casualties.
    CH-1 to NVIC 8-81 extended to liftboats the same consideration 
permitted for conventional OSVs: relaxation of certain provisions of 46 
CFR subchapter I or T. The Coast Guard is conscious of the economic 
hardship potentially imposed upon owners and operators of existing 
vessels first coming under inspection for certification. Therefore, in 
keeping with the intent of Public Law 96-378, it treated existing 
liftboats differently from new liftboats. CH-1 to NVIC 8-81 did not 
address features that can be addressed only in the design stage, such 
as main-hull strength and damage stability, since modification of 
existing vessels to meet recognized standards in these and other 
features is very costly. Instead, it limited the areas and conditions 
of operation according to vessels' design, including leg strength and 
stability. Over 50 liftboats applied for and received initial 
inspection for certification under CH-1 to NVIC 8-81.
    Recently the Coast Guard became aware of a large number of existing 
liftboats designed and operated on inland waters or on State waters of 
Texas and Louisiana. These vessels are typically operated closer to 
harbors of safe haven than are larger, ocean-going liftboats. In 
response to requests from representatives of these liftboats, the Coast 
Guard revisited the issue of initial inspection for certification of 
existing liftboats. The result was NVIC 8-91. NVIC 8-91 incorporates 
the guidance of NVIC 8-81 and its CH-1, and provides further guidance 
toward a level of safety for smaller, existing liftboats equivalent to 
that for larger, existing or new, liftboats.
    NVIC 8-91 is available for inspection and copying in the public 
docket. Also, copies of it are available from the Commanding Officer, 
Marine Safety Center; 400 Seventh Street SW., Washington, DC 20590-
0001; Attn: NVICs. NVIC 8-91 costs $1.75, payable, in advance, by check 
or money order to ``Treasury of the United States''.

Intent

    This interim rule applies to new OSVs: OSVs contracted for after 
these regulations take effect. It also applies to existing OSVs, 
including pre-1979 OSVs, if the owners of these OSVs wish.
    Many of the requirements in this interim rule are similar to 
corresponding requirements in 46 CFR subchapters I and T. The Coast 
Guard has made every effort to select the most appropriate of those. 
The Coast Guard, when able, has modified existing regulations to 
consider the unique operation of OSVs and to recognize many of the 
policies developed for these vessels throughout the years where 
equivalent levels of safety have been demonstrated. When existing 
regulations have seemed confusing or in any way not clear enough as 
they apply to OSVs, the Coast Guard has made editorial changes. To the 
extent that this rule addresses the same issues as NVIC 8-91, it 
addresses them in the same way. The large majority of existing vessels 
have been certificated for restricted service because of their original 
designs. However, new liftboats should enjoy a wider and less 
restrictive scope of operation than those certificated before 
establishment of these regulations because compliance with standards of 
structural strength and of stability will render them able to do more.

Associated Regulatory Projects

    On February 13, 1990, the Coast Guard published (55 FR 5120) an 
NPRM, under CGD 89-037, entitled Stability Design and Operational 
Regulations. On September 11, 1992, it published (57 FR 41812) the 
final rule. This interim rule subsumes that one. Both incorporate, for 
inspected vessels, recently adopted amendments to the International 
Convention for the Safety of Life at Sea, 1974, as amended (SOLAS). 
Both seek to reduce the potential for vessels' capsizing caused by 
defective designs or operations. This interim rule adds Secs. 131.220 
(e), (f), and (g); 131.513; and 131.620(d) to 46 CFR part 131.

Discussion of Specific Provisions, Including Comments on and Changes to 
the NPRM of May 9, 1989

    The Coast Guard sought comments on all aspects of these 
regulations--from owners, operators, architects, and builders of 
vessels; material vendors, insurers, surveyors, and other persons 
involved with OSVs; and interested members of the public. It invited 
and encouraged interested persons to participate in this rulemaking by 
submitting written views, data, or arguments. It received 20 letters, 
containing 194 comments. It evaluated all comments, and incorporated 
many of their recommendations into this interim rule. Comments received 
are discussed below. Where section numbers in this rule differ from 
their counterparts in the NPRM, the counterparts appear in brackets. 

[[Page 57633]]

    One commenter suggested that 46 U.S.C. 3301(3) is flag-blind, and 
questioned what standards would apply to foreign-flag OSVs. In general, 
the operation of foreign-flag OSVs would not be permitted, since U.S. 
Customs has determined that the carriage of goods between offshore 
platforms in U.S. waters constitutes ``coastwise trade'' and would, 
therefore, if accomplished by these OSVs, violate the Jones Act. No 
OSVs carry goods between platforms in U.S. waters and a foreign port or 
the U.S. Virgin Islands. Current industry practice and platform 
locations make such trade highly unlikely.
    One commenter asked for clarification of the Coast Guard's intent 
regarding different rules for OSVs depending on when vessels were 
built. Vessels previously inspected under 46 CFR subchapter I or T 
would continue to be inspected under those rules, coming under this 
interim rule only at the owners' option.
    Two commenters stated that applicability provisions should require 
a vessel to complete significant construction within a reasonable time, 
to prevent circumvention of the new standards. The Coast Guard agrees 
and has inserted new Sec. 125.100(c), to require 24 months for 
construction of the vessel.
    One commenter noted that the proposed rule did not adequately 
address the carriage of Noxious Liquid Substances (NLSs). The Coast 
Guard agrees and has added Sec. 125.120. It has also updated the 
provisions of 46 CFR subpart 98.31 and moved them into this section to 
clarify the carriage of NLSs on OSVs.
    Several comments concerned reference in Sec. 125.150 (Sec. 125.140) 
to proposed 46 CFR subchapter W (CGD 84-069), Lifesaving Equipment. The 
manager of that project will consider them along with others related to 
that project. Rather than refer to lifesaving requirements proposed for 
subchapter W, this interim rule refers to those already in subchapter 
I. When proposed subchapter W is promulgated, those of its requirements 
that govern OSVs will likely go into subchapter L, where part 133 is 
reserved for them. The Coast Guard has revised Sec. 125.150 
(Sec. 125.140).
    One commenter questioned the definition of ``cargo gear'' in 
(Sec. 125.150(d)) and asked how this Interim Rule would treat cranes. 
Since OSVs seldom carry cargo gear in the traditional sense, but often 
carry cranes, the Coast Guard enlarged this definition to specifically 
comprehend cranes. (Sec. 125.150(d)) has become Sec. 125.160 Crane, 
which specifically comprehends cranes.
    One commenter urged use of ``offshore'' in the definition of 
``Restricted Service'' in Sec. 125.160 (Sec. 125.150(w)), parallel to 
its use in the definition of ``Offshore Supply Vessel'' in Sec. 125.160 
(Sec. 125.150(s)). A review of the legislative history of applicable 
statutes discloses no congressional intent to create a regulation-free 
zone for OSVs operating ``inshore or inland.'' ``Offshore'' as it 
figures in ``offshore supply vessel'' suggests the place where OSVs are 
designed and intended to operate, not where they happen to be operating 
at a particular moment. Accordingly, any OSV (including any liftboat)--
operating on the navigable waters of the United States, and either 
carrying goods, supplies, or equipment, or providing service to or 
support of exploration, exploitation, or production of offshore mineral 
or energy resources--is subject to inspection. Section 125.160, 
therefore, does not include the use of ``offshore'' in the definition 
of ``Restricted Service''.
    Two commenters indicated the practice of incorporation by reference 
in Sec. 125.180 (Sec. 125.170) to be too troublesome and confusing. The 
practice is a procedure used by Federal agencies to regulate by 
reference to material already published and available elsewhere. This 
practice reduces the redundancy and bulk of the Federal Register and of 
the Code of Federal Regulations.
    One commenter pointed out that the current edition, rather than an 
outdated edition, of the ABS's Rules for Mobile Offshore Drilling Units 
(MODUs) should be incorporated by reference in Sec. 125.170. The NPRM 
of May 9, 1989, would indeed have incorporated by reference the Rules 
for MODUs from 1985. But later editions appeared in 1988 and 1991, and 
the parts of this final rule governing the leg strength and structural 
design of liftboats incorporate these instead. There has been 
considerable discussion in the Coast Guard and industry regarding the 
new ``unity check'' equation in the newer editions of the ABS's Rules, 
especially regarding its applicability to liftboat legs. This rule 
incorporates by reference the Rules for MODUs from 1994; but, as the 
preamble points out elsewhere, other forms of the ``unity check'' may 
be acceptable too.
    One commenter suggested incorporating by reference in Sec. 125.180 
(Sec. 125.170) the standards of either the International Standards 
Organization (ISO 614, 1095, 3254, 3903, and 5779) or the British 
Standards Institute (BSI BS MA 24 & 25) for windows used in the side 
shell and in the deckhouse, and noted that either standard would affect 
proposed Sec. 127.420. The Coast Guard does not agree. It has not 
evaluated either, to determine the impact of requiring their use. They 
are not known to most small U.S. shipyards, and casualty information 
has not demonstrated that such detailed standards are necessary. The 
Coast Guard may in any case accept compliance with them as 
demonstrating sufficient strength to satisfy the requirements in 
Sec. 127.420. But it has not changed Sec. 125.180 (Sec. 125.170).
    One commenter suggested rewording (Sec. 125.180) to clarify the 
responsibility of the Marine Inspector regarding notice of deficiencies 
found. The responsibilities of the Marine Inspector are a matter of 
Coast Guard policy and appear in the Marine Safety Manual, NVICs, and 
Commandant Instructions. Because they are a matter of policy, because 
other subchapters concerning inspections leave policy to those sources, 
the Coast Guard has removed this section.
    One commenter thought Sec. 126.100 would give the Marine Inspector 
too much power to require tests and inspections. The Coast Guard does 
not agree. To ensure compliance with regulations, the Inspector needs 
flexibility to increase the scope of an inspection according to the 
conditions found when a vessel is boarded for whatever reason. The 
Inspector has to follow guidance from the cognizant OCMI; this, 
together with the appeal procedures available to the owner, keeps the 
Inspector from wielding excessive power.
    One commenter suggested that Sec. 126.110 require the owner or 
operator of a vessel to report an accident and make the vessel 
available for inspection afterward. Casualty reporting is already 
required under Sec. 131.110, but the Coast Guard agrees that the burden 
to make the vessel available for inspection after a casualty or when 
important repairs or renewals are going on should rest with the owner 
or operator. It has changed Sec. 126.110.
    One commenter stated that the Permit to Proceed prescribed by 
Sec. 126.120 should indicate whether the vessel may carry ``goods, 
supplies, (and) equipment'' as well as cargo and offshore workers. The 
Coast Guard agrees and has reworded Sec. 126.120(c).
    (Sec. 126.130), ``Inspection of Cargo Gear'', and (Sec. 126.140), 
``Cranes'', have been merged in current Sec. 126.130, ``Cranes'', 
because few OSVs carry any cargo gear except cranes.
    One commenter urged the Coast Guard to revise Sec. 126.140 
(Sec. 126.150), to delegate drydockings for credit to classification 
societies' surveyors. 

[[Page 57634]]
Under the Maritime Regulatory Reform Plan the Coast Guard may, in the 
future, further delegate responsibilities for inspections to 
classification societies' surveyors or other third parties. In the 
meantime in rare cases, considering them on their individual merits, 
the OCMI may accept alternatives, under the authority of Sec. 125.170 
(Sec. 125.160), if he or she is satisfied that they afford an 
equivalent level of safety.
    On its own the Coast Guard realized that Sec. 126.140 
(Sec. 126.150) did not require an internal structural examination in 
conjunction with a drydocking for credit. For years it was standard 
practice to examine the internal structural members whenever a vessel 
was hauled out or placed on drydock. In 1988 the drydocking regulations 
in 46 CFR subchapter I changed; now they distinguish between 
``drydock'' and ``internal structural'' examinations. To clarify the 
intent of this rule, the Coast Guard has revised Sec. 126.140 
(Sec. 126.150) to specifically require an internal structural 
examination at the same interval as drydocking, but not necessarily at 
the same time.
    Several commenters asked that Sec. 126.150 (Sec. 126.160) clarify 
which OCMI an owner should notify when repairs or alternations are due. 
The OCMI having jurisdiction in the zone where the repairs or 
alterations will occur is the one. Section 126.150(a) makes this 
explicit.
    One commenter found confusing the separation of requirements in 
Sec. 126.150 (Sec. 126.160) from similar requirements in (Sec. 131.220) 
and (Sec. 131.230), on reporting after certain accidents and reporting 
before certain repairs. The Coast Guard agrees and has combined all 
such requirements in Sec. 126.150(a), eliminating (Sec. 131.220) and 
(Sec. 131.230).
    One commenter stated that Sec. 126.160(c)(1) (Sec. 126.170(c)(1)), 
should apply to a vessel under way and one in port but not to one in a 
shipyard or in a ship-repair facility, because these last two are 
subject to requirements of the Occupational Safety and Health 
Administration (OSHA) in 29 CFR part 1915. The Memorandum of 
Understanding between OSHA and the Coast Guard indicates, however, that 
the Coast Guard is the lead agency on inspected vessels. This section 
persists as proposed.
    One commenter urged that the rule treat carriage of 36 or fewer 
offshore workers not as matter of applicability, as in 
(Sec. 125.100(a)(2)), but as an absolute limit, as in (Sec. 125.180). 
The Coast Guard agrees; it has shifted the burden of (Sec. 125.180) 
into current Sec. 126.170 and eliminated (Sec. 125.100(a)(2)).
    One commenter observed that Sec. 126.170 (Sec. 126.180) does not 
address how offshore workers get on and off the vessel. The Coast Guard 
does not perceive this as a problem and knows of no statistical 
evidence to suggest that it is. This section persists as proposed.
    Two commenters challenged (Sec. 126.180) over the number of 
offshore workers on OSV may carry. One commenter held a limit of 36 
workers, at least when the vessel was operating overseas, too 
restrictive while the other held an allowance of more than 12, whatever 
the circumstances, too permissive. The Coast Guard does not agree with 
either commenter. The carriage of offshore worker is still limited to 
16 on domestic voyages and 12 on international voyages, except aboard 
vessels designed and constructed to the stringent damage-stability 
requirements in current Sec. 174.205. The actual number a vessel may 
carry will depend on the OCMI at the initial Inspection for 
Certification. The OCMI will consider space on the deck, sizes of the 
staterooms, availability of seating, number of bunks, number of toilets 
and washbasins, size of the vessel, and whether the offshore workers 
will be aboard for more than 24 hours. This section persists as 
proposed.
    One commenter stated that Form CG-3752, ``Application for 
Inspection'', called out by (Sec. 126.230), needs revision. The 
commenter is right, and the Coast Guard will accomplish this in its 
next review of its information-collection budget for the Office of 
Management and Budget (OMB).
    One commenter suggested revising Sec. 126.240 to require all pages 
of the Certificate of Inspection to be visible when posted. The Coast 
Guard agrees and has reworded Sec. 126.240 accordingly.
    Form CG-858, ``Certificate of Inspection Amendment'', called out by 
Sec. 126.270, has been discontinued. The Coast Guard has revised 
Sec. 126.270 accordingly, and updated the Marine Safety Manual, volume 
II (change 3).
    The Coast Guard wishes to emphasize that the inspections called for 
by Sec. 126.340 and several other sections are the responsibility of 
the owner or operator in the first instance. Persons authorized by the 
Coast Guard carry out the inspections, but the owner or operator makes 
the vessel available without prompting.
    One commenter stated that the inspections required by Secs. 126.340 
and 126.430 should specifically include liftboat legs. The Coast Guard 
agrees that some inspections should, and has added part 134 (reserved 
in the NPRM), which comprises added provisions for liftboats. The 
inspections required by current Secs. 134.110, ``Initial Inspection'', 
and 134.120, ``Inspection for Certification'', specifically include 
liftboat legs.
    Eight commenters stated that (Sec. 126.350) and (Sec. 126.440) were 
confusing, difficult to decipher, too detailed, and verbose. The Coast 
Guard agrees and has eliminated much of the original text. Section 
126.350(b)(3) refers the reader to subpart 94.35 for guidance on the 
inspection of the installation of lifeboats, rescue boats, davits, and 
winches. Section 126.440 likewise refers the reader to Sec. 91.25-15.
    One commenter stated that the scope of reinspection in Sec. 126.520 
should be better defined. The Coast Guard does not agree. Once a vessel 
has passed inspection and received a Certificate of Inspection (COI), 
that vessel should be in compliance with the terms of its COI at all 
future times. To ensure this compliance, the Marine Inspector needs the 
flexibility to increase the scope of inspections according to 
conditions found. See the discussion of Sec. 126.100, above.
    On January 25, 1990, the Coast Guard published (55 FR 2525) 
alternative provisions for reinspection of OSVs in foreign ports under 
CGD 82-004a. These provisions now appear here, incorporated in 
Sec. 126.530.
    Two commenters stated that Sec. 127.110(e), ``Electrical 
engineering'', should incorporate Sec. 110.25 of this chapter both for 
vessels of under 100 gross tons and for vessels of 100 or more gross 
tons. The Coast Guard does not agree. The electrical requirements for 
vessels of under 100 gross tons are similar to the requirements in 
proposed subchapter T, which, in their current form, do not seem to 
have degraded the safety and reliability of electrical systems. This 
section persists as proposed.
    Section 127.120(b) has changed to reflect the Marine Safety 
Center's new address.
    Three commenters stated that Sec. 127.240, ``Means of escape'', 
should require more. The first commenter urged adding that ``at least 
two means of escape from the same deck lead directly to the outside of 
the deckhouse'' and cited an accident where protective metal plates on 
windows were secured from the outside of the deckhouse. The second 
urged adding that ``all exposed peripheries within five feet of the 
scuttle be provided with permanent rails or bulwarks''. The third urged 
adding that vertical ladders be strong enough to support 1000 pounds. 
The Coast Guard disagrees with these additions, but has added 
Sec. 127.440 to 

[[Page 57635]]
require that any covering or protection placed over a window or 
porthole be capable of being readily removed or opened without anyone's 
having to go onto a weather deck.
    Two commenters considered Sec. 127.250, ``Ventilation for enclosed 
spaces'', too broad and yet too sparse in detail on remote stopping of 
ventilation. The requirements for remote stopping appear at 
Sec. 129.540; adding them to Sec. 127.250 would be redundant.
    One commenter found Sec. 127.270(g), on separating crew members' 
and offshore workers' accommodations impracticable and unnecessary. The 
NPRM, however, had allowed approval of an alternative arrangement by 
the OCMI; this Interim Rule allows it also.
    None commenters stated that Sec. 127.280, now ``Construction and 
arrangement of accommodations for crew members and offshore workers'', 
needed reworking. The Coast Guard agrees and has made several changes. 
From Sec. 127.280(b)(1) it has dropped the requirements that seating 
must not be intended for any other use and that seating with crew 
members is not acceptable. From Sec. 127.280(b)(2) if has dropped the 
requirement for aircraft-style seating when offshore workers are aboard 
for more than 12 hours. From Sec. 127.280(b)(4) it has dropped the 
requirement of separate toilets and washbasins for offshore workers. 
And from Sec. 127.280(d) it has dropped the requirement that boundary 
bulkheads and decks separating crew members' and offshore workers' 
accommodations from machinery spaces must be of ``A'' class 
construction as defined by Sec. 92.07-5 of this chapter for vessels of 
less than 100 gross tons.
    One commenter wanted Sec. 127.320, ``Storm rails'', revised to read 
that suitable storm rails must be installed in all passageways and at 
the deckhouse sides, ``including in way of inclined ladders''--wherever 
persons aboard have normal access. The Coast Guard agrees and has 
corrected this section.
    Two commenters stated that every covering or protection placed over 
a window or porthole during heavy weather should be capable of being 
readily removed or opened without anyone's having to go onto a weather 
deck. The Coast Guard agrees and has added Sec. 127.440, ``Operability 
of Window Coverings''.
    One commenter wanted Sec. 127.420 to require windows and portlights 
to meet standards of the British Standards Institute if the vessel 
operated on oceans or partially protected routes. The Coast Guard 
disagrees because it has not evaluated these standards to determine the 
impact of their use, because they are not known to most small 
shipyards, and because reports and statistics on casualties have not 
demonstrated their necessity. This section persists as proposed.
    One commenter stated that there is an enormous difference between 
vital systems for lifeboats and those for conventional OSVs and that 
Sec. 128.130 should reflect this. The Coast Guard disagrees, respecting 
most vital systems. However, to affirm the stature of liftboat-jacking 
systems as vital systems it has moved its treatment of these from this 
section to part 134.
    One commenter stated that the constraint on design ordained by 
(Sec. 128.310(b)), ``the use of a fuel with a flashpoint of lower than 
110 degrees F. must be specifically approved by Commandant (G-MMS), 
except in an engine for a gasoline-powered rescue boat'', would be more 
appropriate in subpart I of part 131 as a constraint on operations. The 
Coast Guard does not agree. This constraint should influence the 
design, and the builder should seek the Commandant's approval, if 
necessary, early in design so any changes may occur before actual 
construction begins. This section persists as proposed.
    One commenter stated that Sec. 128.440 is too broad to establish 
minimum standards for designers and builders and that liftboats would 
have to meet the same requirements for bilge systems that MODUs already 
have to meet. The Coast Guard agrees in part. This section now contains 
paragraphs (a) and (b). Paragraph (a) reads, ``Except as provided by 
this section, each bilge-system installation must comply with 
Secs. 56.50-50 and 56.50-55 of this chapter''. Paragraph (b) comprises 
the text proposed for Sec. 128.440 as a whole.
    One commenter believed that most switchboards aboard liftboats are 
too small for handrails as required by Sec. 129.330(c). The Coast Guard 
does not agree. A non-conductive handrail is essential to the safety of 
crew members when operating the switchboard in any kind of seaway. This 
section persists as proposed.
    One commenter stated that Sec. 129.440(a) should also require 
emergency lighting in the engineroom. The Coast Guard agrees and has 
reworded the section to include working (machinery) spaces.
    One commenter stated that Sec. 129.530 should not exempt vessels of 
under 100 gross tons from installing a general alarm. The Coast Guard 
agrees and has reworded this section.
    One commenter stated that Sec. 129.540(a) should not exempt vessels 
of under 100 gross tons from installing remote stopping-systems. The 
Coast Guard does not agree. Elsewhere, this interim rule requires 
vessels of under 100 gross tons to have remote means of shutting down 
ventilation and a means of shutting down main propulsion machinery, 
both from the pilothouse. This section persists as proposed.
    One commenter called redundant the requirement of Sec. 130.120(c), 
that a vessel have a propulsion-control system operable from the 
pilothouse that shuts down main machinery independent of the remote 
stopping-system required by Sec. 129.540(b)(1). The Coast Guard agrees 
and has changed Sec. 130.120(c) so that a system in compliance with 
Sec. 129.540 is also, by that fact, in compliance with Sec. 130.120.
    One commenter stated that Sec. 130.120(d) should require most OSVs 
with controllable-pitch propellers to fail in the ahead mode since they 
normally back into rigs but should require most liftboats with 
controllable-pitch propellers to fail in the astern mode since they 
normally head into rigs. The Coast Guard disagrees. Statistics on 
accidents do not establish this as a problem. Maneuvering in a harbor 
or in close quarters with other vessels could prove disastrous if 
controllable-pitch propellers failed in any mode that causes the 
propulsion engine to over speed or the pitch of the propellers to 
increase. This section persists as proposed.
    One commenter stated that Sec. 130.130(j)(4) was unclear about the 
meaning of ``materially equivalent''. When a hydraulic-helm steering-
system is installed with a duplicate power system for the main steering 
gear, the duplicate power system may be used to operate winch motors on 
deck or similar equipment if its hydraulic piping, for instance, is 
essentially identical to that of the steering system.
    One commenter asked whether an ``orbitrol-type'' system counts as a 
hydraulic-helm steering-system according to Sec. 130.140(a)(2). An 
orbitrol system is a type of hydraulic-helm steering-system.
    One commenter stated that the reference by Sec. 130.140(b)(15) to 
the ``hydraulic helm unit'' should be eliminated. The Coast Guard 
agrees, and has changed the section to read ``Manual capability to 
center and steady the rudder if the vessel loses normal steering 
power.''
    One commenter stated that liftboats approach docks and offshore 
platforms head on and that, therefore, Sec. 130.140 should not require 
after steering. After steering enters Sec. 130.140(a)(1) by reference 
to subchapter F (Sec. 58.25-50), which does not require it if the 
steering 

[[Page 57636]]
system complies with standards embodied in Sec. 130.140(b) and if the 
vessel has adequate visibility when going astern. This section persists 
as proposed.
    The requirement for gas masks in Sec. 130.230 (Sec. 130.240) has 
given way to CGD 86-036, ``Updating Approval and Carriage Requirements 
for Breathing Apparatus'', published (57 FR 48320) as a final rule on 
October 23, 1992. Now a self-contained breathing apparatus (SCBA) is 
required for each refrigeration system exceeding 20 cubic feet of 
storage capacity and using ammonia or other hazardous gas, or exceeding 
1000 cubic feet of storage capacity and using a fluorocarbon as 
refrigerant.
    Two commenters called excessive the requirement in Sec. 130.240 
(Sec. 130.250), that liftboats comply with the ABS's rules for anchors. 
One commenter stated that the ABS's rules are an option for MODUs and 
should be for liftboats. The other stated that liftboats do not and 
would not use anchors often, and that this rule should allow smaller 
anchors than those allowed by the ABS's rules. The Coast Guard does not 
agree. Only MODUs that are not self-propelled and are towed from place 
to place are free to ignore those rules. Liftboats do not fit in that 
category; they need anchors in emergencies. They may, however, comply 
with rules from other classification societies instead of the ABS's 
rules, upon approval of the Commandant. This section persists as 
proposed.
    One commenter stated that a new section should be added to require 
cargo fittings on weather decks to provide adequate lashing-points for 
deck cargo. The Coast Guard considers a uniform requirement on lashing 
an unnecessary economic burden and will leave the matter to the owners' 
desires.
    One commenter found the requirements in Secs. 130.310 for a marine 
radar and 130.320 for an electronic position-fixing device inadequate 
to assure navigational safety. The Coast Guard disagrees. There is a 
wide variety of radar and electronic position-fixing devices available, 
at many different prices. The Coast Guard does not prefer one to 
another. These sections persist as proposed.
    Two commenters wanted a new section requiring Navtex receivers and 
fathometers. The Federal Communications Commission required on August 
1, 1993 (47 CFR 80.1065(b)(1)), that OSVs of 300 or more gross tons 
carry Navtex receivers. The Coast Guard will not require that OSVs of 
under 300 gross tons do the same. OSVs are in constant contact with 
their bases or the offshore facilities they are serving. Using the 
required charts and electronic position-fixing devices, vessels will 
know depths of water well enough without fathometers. The Coast Guard 
considers a uniform requirement an unnecessary economic burden and will 
leave the matter to the owners' desires. No section was added.
    One commenter wanted a new Sec. 130.330(c) specifying that, ``when 
operating in foreign waters, an OSV may carry an appropriate foreign 
equivalent of any'' domestic item ``required by paragraph (a) of this 
section.'' The Coast Guard agrees and has added this wording.
    One commenter wanted a new subsection in Sec. 130.440 to require a 
public-address system for announcing instructions, advisories, and 
emergencies from the pilothouse. The Coast Guard disagrees. A general 
alarm in accordance with Sec. 129.530 should serve to alert crew 
members and offshore workers to emergencies. This section persists as 
proposed.
    Two commenters wanted all voids covered by Sec. 130.460(b)(1), 
which already requires sensors for the high-bilge-level alarm in each 
space below the deepest load waterline that contains pumps, motors, or 
electrical equipment. The Coast Guard disagrees. This would be an 
unnecessary economic burden because the flooding of voids without 
apparent reason and without crew members' knowledge has not been a 
cause of casualties to OSVs. This section persists as proposed.
    One commenter wanted a new subsection in part 131, proposed subpart 
I, ``Markings on Vessels'', to require markings on main decks over 
integral fuel and buoyancy tanks, to alert personnel where not to use 
tack welds when securing deck cargo. The Coast Guard disagrees. Using 
tack welds to secure deck cargo is inconsistent with sound policy for 
welding and burning on inspected vessels. Proposed subpart I has become 
current subpart B; otherwise, the subpart persists as proposed.
    One commenter stated that Sec. 131.220(c) (Sec. 131.920(b)) did not 
clearly indicate the datum line for draft measurements. The Coast Guard 
disagrees. This section persists as proposed.
    One commenter stated that Sec. 131.340(a)(5) (Sec. 131.340(1)(v)) 
was unclear where offshore workers should sit and what ``evenly 
distributed'' means. The Coast Guard disagrees. The workers should be 
seated and evenly distributed in the area specified by 
Sec. 127.280(b)(1) (Sec. 127.280(a)(1)). Section Sec. 131.340(a)(5) 
(Sec. 131.340(1)(v) persists as proposed.
    One commenter urged that the instruction in Sec. 131.340(a)(6) 
(Sec. 131.340(1)(vii)) to don lifejackets and immersion suits should be 
reworded. The Coast Guard agrees. Only if immersion suits are required 
aboard should offshore workers have to don them. The Coast Guard has 
reworded this section.
    One commenter recommended that the Coast Guard develop--instead of 
Sec. 131.420(c)(2), under which the OCMI may permit persons practiced 
in the handling of liferafts to substitute for deck officers, able 
seamen, and certificate persons--an appropriate scheme of testing and 
endorsement for persons in charge of survival craft. The whole point of 
Sec. 131.420(c)(2) is to require either persons tested and endorsed, or 
persons demonstrably competent by standards less rigid, to be in charge 
of survival craft. But the Coast Guard will consider this 
recommendation while developing a rule to revise 46 CFR part 12, 
``Certification of Seaman''.
    One commenter suggested that in Sec. 131.505(a) the word ``voyage'' 
should be replaced by ``away from shore''. The Coast Guard agrees and 
has reworded this section.
    One commenter stated that Sec. 131.560 as written was directed 
mainly at liftboats and should be rewritten to be directed at OSVs in 
general. The Coast Guard disagrees. Every word applies with full force 
to OSVs in general. This section persists as proposed.
    One commenter recommended that Sec. 131.580 cover the servicing of 
inflatable buoyant apparatus. The Coast Guard agrees and has reworded 
this section.
    One commenter suggested that in Sec. 131.610(a) the words ``Each 
OSV'' should read ``Each vessel''. The Coast Guard disagrees. This 
subchapter deals only with OSVs, even though some are liftboats. This 
section persists as proposed.
    The Coast Guard has reworded Sec. 131.860(b) to eliminate both 
paragraph (1)--and with it a reference to SOLAS--and paragraph (2), and 
to clarify its intent on the length of the painter.
    One commenter recommended that Sec. 131.865 cover the marking of 
inflatable buoyant apparatus. The Coast Guard agrees and has reworded 
this section.
    One commenter suggested that the markings prescribed by 
Sec. 131.893 for watertight doors and hatches read ``WATERTIGHT DOOR--
KEEP CLOSED EXCEPT FOR PASSAGE'' and ``WATERTIGHT HATCH--KEEP CLOSED 
WHEN NOT IN USE''. The Coast Guard agrees and has reworded this 
section.

[[Page 57637]]

    One commenter recommended adding ``operating a vessel while 
intoxicated'' to the grounds of criminal liability set forth by 
Sec. 131.905(a)(3) (Sec. 131.1005(a)(3)). The Coast Guard disagrees 
because the section already implies those grounds.
    Several commenters expressed the concern that, considering the 
service of OSVs, hand-operated fire pumps were inadequate on OSVs under 
65 feet in length. The Coast Guard disagrees. The requirements in 
Sec. 132.100 are similar to those in proposed subchapter T, which are 
similar to those in current subchapter T, which have caused no 
perceptible decline in safety. This section persists as proposed.
    One commenter stated that Sec. 132.120(j) could be construed to 
prohibit a ballast pump from use as a backup or standby fire pump. It 
can indeed be so construed, where a ballast pump is ``connected to a 
line for flammable or combustible liquid''; the Coast Guard wants it so 
construed, there--though not elsewhere. This section persists as 
proposed.
    The Coast Guard has incorporated Chapter 4 of NFPA 10 into 
Sec. 132.350(c)(1) as the standard to use when inspecting and testing 
portable fire extinguishers. It has deleted the requirements for 
portable fire extinguishers in proposed Table 132.350(a). It has 
combined the requirements for semiportable and fixed fire-extinguishing 
systems in proposed Tables 132.350 (a) and (b) into Table 132.350.
    After reviewing spoken comments, made during the hearings in New 
Orleans, and written comments, the Coast Guard has consolidated items 
peculiar to liftboats spread throughout the NPRM into previously 
reserved part 134, now entitled ``Added Provisions for Liftboats.'' 
Part 133 is reserved for ``Lifesaving Systems''.
    Two commenters will applaud Sec. 134.140(a)(1), which clarifies a 
matter left ambiguous by proposed Sec. 127.210(b)(1): whether the main 
hull of a liftboat constitutes part of the ``supporting structure''. It 
does, and must comply with section 3.11 of the ABS's Rules for Building 
and Classing Mobile Offshore Drilling Units.
    Five commenters found a ``K'' factor of 2 for leg strength in 
Sec. 134.140(a)(3) (Sec. 127.210(b)(3)) too restrictive. A ``K'' factor 
of 2 is conservative and in any case is just a starting-point. Section 
134.140(a)(3) (Sec. 127.210(b)(3)) remains as before. The Coast Guard 
realizes that there may be any number of ways to calculate leg 
strength, so it has retained Sec. 134.140(b) (Sec. 127.210(c)), to 
allow use of the standards of any classification society, or other 
established standard acceptable to Commandant (G-MMS), in determining 
structural strength.
    Four commenters found the requirement in Sec. 134.150(a), 
(Sec. 128.460), for design of rack-and-pinion jacking-systems to the 
standard of American Gear Manufacturer's Association inappropriate 
because the systems operate in a low-duty-cycle, slow, non-reversing, 
nearly static condition. The Coast Guard agrees and has rewritten 
Sec. 134.150(a) (Sec. 128.460) so that these systems must comply with 
sections 4/1.13.1 through 4/1.13.3 of ABS's Rules for Building and 
Classing Mobile Offshore Drilling Units.
    Four commenters stated that the requirement in Sec. 134.150(b) 
(Sec. 130.210), for a loss of power or a failure of any one component 
if the liftboat-jacking system to activate an alarm, is impracticable. 
The Coast Guard agrees and has revised Sec. 134.150(b) to require a 
visible and audible alarm for loss of power, loss of pressure in the 
hydraulic system, or low hydraulic-fluid level at the operating 
station.
    Three commenters suggested requiring a tilt-level alarm on 
liftboats. The Coast Guard disagrees. A liftboat constructed to these 
rules will enjoy an increased level of safety over existing liftboats, 
and a tilt-level alarm is not essential for vessel safety. Owners may 
or may not install a tilt-level alarm, according to their desires.
    Section 134.170 revises the requirement in (Sec. 131.1085), that 
each liftboat carry an operating manual. For the reference to 
Sec. 109.212(c) it substitutes its own list.
    To address the unique operating characteristics of liftboats, the 
Coast Guard has added Sec. 134.180. This requires piping for fire-main 
suction while a liftboat is elevated.
    Ten commenters opposed, or raised questions concerning, the 
requirement in (Sec. 174.180), that liftboats meet the same criteria 
for stability, whether intact or damaged, as conventional OSVs. It was 
never the Coast Guard's intention to impose on liftboats criteria for 
stability of conventional ship-shaped hulls.
    Liftboats inspected under subchapter L need not meet the criteria 
in current subpart G of part 174 of subchapter S. Liftboats in 
unrestricted service must now, according to Sec. 174.250, meet the same 
criteria for intact, damaged, and on-bottom stability as MODUs in 
subpart C of part 174 of subchapter S. Liftboats in restricted service 
must now, according to Sec. 174.255, meet the criteria for intact, 
damaged, and on-bottom stability in Sec. 174.255 itself. Both sets of 
criteria for liftboats inspected under subchapter L--in unrestricted 
service, and in restricted service--closely follow guidelines of NVIC 
8-91.
    Three commenters opposed liftboats' having to meet criteria for 
damaged stability in Secs. 174.195-205. As outlined above, these 
criteria for damaged stability in subchapter G do not now apply to 
liftboats, since now all criteria for damaged stability for liftboats 
is contained in subpart H.
    Three commenters stated that designing vessels to the criteria for 
damaged stability in Sec. 174.205 is too hard. The Coast Guard 
disagrees. Vessels have already been designed, and built, to these 
criteria. Anyway, more stringent criteria for survivability are 
warranted for vessels that carry more than 16 offshore workers, and 
Sec. 174.205 applies only to vessels that do.
    Two commenters stated that all OSVs, including liftboats, should 
have to meet the standards for survivability of Sec. 174.205(e), 
whether they carry more than 16 offshore workers or not. The Coast 
Guard disagrees. Damaged stability is not necessary on small passenger-
vessels or small miscellaneous vessels unless the number of people 
aboard causes special concern; at least no statistical or anecdotal 
evidence suggests that it is.
    One commenter found the intent of proposed Sec. 174.205(f) unclear. 
So, on a later look, did the Coast Guard. Section 174.205(f) now reads: 
``For paragraph (a) of this section, the buoyancy of any superstructure 
directly above the side damaged must be considered in the most 
unfavorable condition.''
    The dimension requirement in Sec. 174.220(a)(1) for hatches 
extending above the weather deck has been changed from 12 inches to 
17\1/2\ inches to conform with loadline regulations in Sec. 42.15-
25(a)(ii) of this chapter. Also the dimension requirement in 
Sec. 174.220(d) for watertight coamings in conjunction with 
weathertight doors has been changed from 6 inches to 15 inches to 
conform with loadline regulations in Sec. 42.15-10(b) of this chapter.
    One commenter recommended adding a statement to Sec. 174.255(c) 
(Sec. 174.250(e)), that unless a liftboat could endure 100 knots of 
wind under severe-storm conditions it would be limited to service 
within 12 hours of a harbor of safe refuge. The Coast Guard disagrees. 
The definition of ``restricted service'' in Sec. 125.160 already 
imposes this limit. Another commenter stated that Sec. 174.255(c) 
(Sec. 174.250(e)), requires the same on-bottom stability for a liftboat 
in restricted service as for a MODU, or for a liftboat in unrestricted 
service. A liftboat in restricted service must endure 70 knots of wind 
under normal operating-conditions through its 

[[Page 57638]]
area of operation and 100 knots under severe-storm conditions in a safe 
location, if the safe location is other than a harbor of safe refuge. A 
MODU, or a liftboat in unrestricted service, must endure 70 knots of 
wind under normal operating-conditions everywhere and 100 knots under 
severe-storm conditions everywhere. To better clarify this, the Coast 
Guard has added to Sec. 174.255(c): ``* * * winds of 70 knots under 
normal operating-conditions and of 100 knots for severe-storm 
conditions when elevated in a safe location, if this location is other 
than a harbor of safe refuge.''
    One commenter suggested adding another section to Sec. 174.255 
(Sec. 174.250), requiring that a vessel show reserve leg-height while 
both jacked up and subject to 100 knots of wind if it would qualify for 
unrestricted service. The Coast Guard disagrees. It considers reserve 
leg-height in determining a route, given restricted service, not in 
determining whether a liftboat qualifies for unrestricted rather than 
restricted service.
    One commenter called arbitrary a requirement in Sec. 174.260 
(Sec. 174.255), of 24 inches as minimum freeboard for liftboats. The 
Coast Guard disagrees. The requirement of 24 inches as minimum 
freeboard first appeared in CH-1 to NVIC 8-81 on March 23, 1988, and 
since then has become accepted by industry as prudent for avoiding the 
adverse effects of water on deck.

Incorporation by Reference

    The Director of the Federal Register has approved the material in 
Sec. 125.180 for incorporation by reference under 5 U.S.C. 552 and 1 
CFR part 51. The material is available as indicated in Sec. 125.180.

Units of Measure

    This interim rule employs British units of measure throughout. 
Federal policy now favors ``hard metric'' throughout. In the absence of 
compelling reason to the contrary, the final rule will employ metric 
units of measure throughout.

Regulatory Assessment

    This interim rule is a significant regulatory action under section 
3(f) of Executive Order 12866 and is significant under the regulatory 
policies and procedures of the Department of Transportation (44 FR 
11034 (February 26, 1979)). It has been reviewed by the Office of 
Management and Budget under that Order. The Coast Guard has prepared a 
Regulatory Assessment and placed it in the rulemaking docket. The 
assessment may be inspected and copied at the address listed under 
ADDRESSES, above.

a. Costs for Conventional OSVs

    As of December 1987, there were 584 OSVs certificated, 407 of which 
were of 100 or more gross tons. In evaluating the effect of this 
interim rule, the Coast Guard considered all costs and benefits of this 
rule in constant dollars.
    The added cost to construct a conventional OSV under this rule, 
compared to that under existing regulations, expressed as a percentage 
of the initial construction cost for each OSV, comes to:
    1. Around 2.3 percent for each conventional OSV of less than 100 
gross tons.
    2. Around 0.5 percent for each conventional OSV of 100 or more 
gross tons.
    If 90 large OSVs and 50 small OSVs are built in the six years after 
the rule becomes effective, the cost of this rule to the industry will 
come to around $0.8 million a year.
    Since 1987 there have been few, if any, OSVs built, because of the 
downturn in the offshore industry. For this reason the Coast Guard's 
assumption on the number of OSVs to be built in the next 6 years may be 
inappropriate. The Coast Guard encourages comments from industry on the 
current cost to construct an OSV and on the estimated number of OSVs 
that might be built in the next 6 years.
    The principal benefits of this rule will be (1) a vessel better 
equipped, with the authorization to carry more than twice as many 
offshore workers and up to full capacity of the tanks for liquid 
drilling-fluid; (2) increased safety for crew members and offshore 
workers, due to the damage-stability requirements; (3) a vessel less 
likely to suffer damage resulting in total loss of the vessel; and (4) 
a crew better prepared to deal with emergencies. The economic value of 
these benefits is difficult to quantify, as it depends on a vessel's 
design, operational procedures, and contractual arrangements. However, 
even if this rule saves just 30% of the expense of damages due to 
casualties, the economic value--quite apart from the first, second, and 
fourth of the four ``principal benefits''--of this rule will more than 
offset the economic costs.

b. Costs for Liftboats

    This Interim Rule will affect small business-entities in the form 
of liftboats. (See Small Entities, below.) These vessels have not had 
to meet standards of Coast Guard inspections. Because the Coast Guard 
has seldom dealt with liftboats during design and construction, it has 
no accurate mechanism for determining additional costs that may be 
incurred by owners of new liftboats required to meet this rule. In the 
NPRM, the Coast Guard sought information concerning such costs that 
might be borne by owners and operators of liftboats resulting from 
newly imposed inspection requirements. One written comment did offer a 
few data associated with costs. Based upon those data, modifications to 
the draft regulatory evaluation came about.
    The Coast Guard reached several designers, builders, and owners of 
liftboats as it prepared this final rule. These people estimated that a 
large liftboat (of less than 300 gross tons with legs 200 feet long) 
would cost between $2 and $4 million to design and build, while a 
liftboat of less than 100 gross tons would cost about $1 million to 
design and build. These people believe that, if design took account of 
this rule from the start, the non-recurring cost associated with 
construction of a liftboat would be minimal--not more than 5% above the 
current estimated construction cost. If it were 10% above, the non-
recurring cost would come to $100,000 for a liftboat of less than 100 
gross tons and between $200,000 and $400,000 for a liftboat of 100 or 
more gross tons. Elements of this non-recurring cost include:
    1. Submittal of plans to the Coast Guard.
    2. Preparation and submittal of a comprehensive operating manual to 
the Coast Guard.
    3. Design and construction of a fail-safe jacking-system.
    4. Piping for fire-main suction while the liftboat is elevated.
    5. Compliance with stricter requirements for lifesaving equipment.
    There would be no recurring cost associated with this rule. There 
is recurring cost associated with salaries of crew members, with 
periodic testing and drydocking, and with biennial inspections and 
reinspections, but this rule does not compound it.
    The economic value due to the ``principal benefits'', of casualties 
and fatalities prevented, is the saving to the liftboat industry 
offered by this rule; it comes from the annual averages for the 
liftboat fleet, 1981 to 1986. The Coast Guard has reviewed the casualty 
and fatality records from 1987 through 1994 for liftboats and has 
deduced that the casualty and fatality statistics follow the same 
general trend as they did in previous years. Therefore, the average 
cost per casualty will not be affected by recent statistics. However, 
since 1987 there have been few, if any, liftboats built, because of the 
downturn in the 

[[Page 57639]]
offshore industry. For this reason the Coast Guard's assumption on the 
cost to build a liftboat may be inappropriate. The Coast Guard 
encourages comments from industry on the current cost to build a 
liftboat and on the estimated number of liftboats that might be built 
in the next few years. The Coast Guard believes that this rule will 
reduce the average cost of total losses in the liftboat fleet, compared 
to that of total losses in the fleet of conventional OSVs, by around 
75-87 percent. This reduced cost of liftboat losses will amount to 
about $65,874 for a lifboat of less than 100 gross tons, which is less 
than the estimated $100,000 for a new liftboat in added costs of 
construction. Similarly, for liftboats of 100 or more gross tons, the 
reduced cost of casualties will be about $183,100, which is near the 
low end of the range estimated for a new liftboat in added costs of 
construction, $200,000-$400,000.
    It is difficult to gauge the impact of this rule on the liftboat 
industry as a whole since those consulted know of no plans for 
construction of new liftboats and since the Coast Guard holds only 
informal estimates of the added costs of construction that may be 
incurred. New liftboats would enjoy some unquantifiable benefits 
heretofore limited to conventional OSVs (for example: carriage of 
unlimited quantities of Grade-E liquid drilling-mud and up to 36 
offshore workers). These unquantifiable benefits, when added to the 
anticipated reductions in casualty costs discussed above, outweigh the 
estimated added cost of construction.

Environment

    The Coast Guard considered the environmental impact of this Interim 
Rule and concluded that under paragraph 2.B.2 of Commandant Instruction 
M16475.1B, the rule is categorically excluded from further 
environmental documentation because of the inconsequential effects that 
it expects the rule to have on the environment. A Categorical Exclusion 
Determination is available in the docket for inspection or copying 
where indicated under ADDRESSES.

Compatibility With International Standards

    The Coast Guard has adopted a policy to evaluate current and new 
rules and, as far as possible, to eliminate requirements that create an 
unwarranted differential between domestic rules and responsible 
international standards. The Coast Guard has therefore compared this 
interim rule to international standards. The Coast Guard has determined 
that this rule does not unnecessarily establish requirements in excess 
of international standards.

Federalism

    The Coast Guard has analyzed this rulemaking in accordance with the 
principles and criteria in Executive Order 12612, and has determined 
that the rulemaking does not have sufficient implications for 
federalism to warrant the preparation of a Federalism Assessment. There 
were no comments submitted to the public docket addressing federalism.

Small Entities

    In accordance with the Regulatory Flexibility Act (5 U.S.C. 601 
through 612), the Coast Guard has considered whether this rulemaking is 
likely to have a significant economic impact on a substantial number of 
small entities. ``Small entities'' include independently owned and 
operated small businesses that are not dominant in their field and that 
would otherwise qualify as ``small business concerns'' under section 3 
of the Small Business Act (15 U.S.C. 632).
    There are about 70 natural or corporate persons that own one 
conventional OSV apiece. (They account for about 12% of existing 
conventional OSVs.) The Coast Guard does not anticipate that there can 
be many more than 20 persons that will own one new conventional OSV 
apiece. (It reaches this figure by assuming that they would likewise 
account for about 12% of the anticipated 140 new conventional OSVs to 
be built in the next six years, or for about 3 a year.) Marginal, one-
time, out-of-pocket expense for initial construction will not exceed 
2.5%, as previously discussed, even if none of the operational 
improvements in safety or flexibility (or other unquantifiable 
benefits) are realized. Recurring operational expense will be nil.
    There are 5 natural or corporate persons that own one liftboat 
apiece. (They account for about 2% of existing liftboats.) The Coast 
Guard does not anticipate that there can be many more than one person 
that own one new liftboat apiece. (It reaches this figure by assuming 
that they would likewise account for about 2% of the anticipated new 
liftboats to be built in the next six years.) Marginal, one-time, out-
of-pocket expense for initial construction will not exceed 10% even if 
none of the operational improvements in safety or flexibility (or other 
unquantifiable benefits) are realized. Recurring operational expense 
will be nil.
    Acting upon these estimates, the Coast Guard certifies under 
section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) 
that this interim rule will not have a significant economic impact on a 
substantial number of small entities.

Vessels, Including Liftboats'', contains guidance on how to apply 
the regulations in 46 CFR subchapters I and T to OSVs.


Sec. 125.110  Carriage of flammable or combustible liquid cargoes in 
bulk.

    (a) Except as provided by this section, no OSV may carry flammable 
or combustible liquid cargoes in bulk without the approval of the 
Commandant (G-MMS).
    (b) An OSV may carry the following in integral tanks:
    (1) Grade-D combustible liquids listed by Sec. 30.25-1 of this 
chapter, in quantities not to exceed 20 percent of the vessel's 
deadweight; except that the vessel may carry drilling fluids and excess 
fuel oil, Grade-E as well as Grade-D, without limit.
    (2) Grade-E combustible liquids listed by Sec. 30.25-1 of this 
chapter, in quantities not to exceed 20 percent of the vessel's 
deadweight; except that the vessel may carry drilling fluids and excess 
fuel oil, Grade-D as well as Grade-E, without limit.
    (c) An OSV may carry the following in fixed independent tanks on 
deck:
    Grade-B and lower-grade fammable and combustible liquids listed by 
Sec. 30.25-1 of this chapter, in quantities not to exceed 20 percent of 
the vessel's deadweight.
    (d) An OSV may carry hazardous materials in portable tanks, in 
compliance with part 64 and subpart 98.30 of this chapter. A po5 
portable tank may be filled or discharged aboard the vessel if 
authorized by an endorsement on the vessel's Certificate of Inspection.


Sec. 125.120  Carriage of noxious liquid substances in bulk.

    (a) Except as provided by this section, no OSV may carry a noxious 
liquid substance (NLS) in bulk without the approval of the Commandant 
(G-MMS).
    (b) An OSV may carry in integral and fixed independent tanks NLSs 
listed by Sec. 153.2 of this chapter, in quantities not to exceed 20 
percent of the vessel's deadweight.
    (c) An OSV carrying NLSs in bulk in integral tanks or fixed 
independent tanks must--
    (1) Meet the definition of oceangoing in 33 CFR 151.05(j);
    (2) Have a Certificate of Inspection or NLS Certificate (issued by 
the Coast Guard) endorsed with the name of the NLS cargo; and
    (3) Have the Cargo Record Book prescribed in Sec. 153.490(a)(1) of 
this chapter.
    (d) An OSV that does not meet the equipment requirements in 
Secs. 153.470 through 153.491 of this chapter may not discharge NLS 
residues to the sea. The vessel's Certificate of Inspection or NLS 
Certificate will contain this restriction.
    (e) An OSV that discharges NLS residue to the sea must meet--

conducted inquiries 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 midperiod examination, is as follows:

    I certify that to the best of my knowledge and belief the above 
is complete and accurate.

    (f) Deficiencies and hazards discovered during the alternative 
midperiod examination made pursuant to this section must be corrected 
if practicable, before the submittal of the report to the OCMI in 
compliance with paragraph (d)(5) of this section. Deficiencies and 
hazards not corrected by the time the report is submitted must be noted 
in the report as ``outstanding.'' Upon receipt of a report indicating 
any outstanding deficiency or hazard, the OCMI will inform the owner or 
operator of the OSV in writing of the time allowed to correct each 
deficiency and hazard and of the method for establishing that each has 
been corrected. When any deficiency or hazard remains uncorrected or 
uneliminated after this time allowed, the OCMI will initiate 
appropriate enforcement.
    (g) Upon receipt of the report, the OCMI will evaluate it and 
determine:
    (1) Whether the OCMI accepts the alternative midperiod examination 
instead of the reinspection required by Sec. 126.510 of this subpart.
    (2) Whether the OSV is in satisfactory condition.
    (3) Whether the vessel continues to be reasonably fit for its 
intended service and route.
    (h) The OCMI may require further information necessary for the 
determinations required by this section. The OCMI will inform the owner 
or operator of the OSV in writing of these determinations.
    (i) If the OCMI, in compliance with paragraph (g) of this section, 
does not accept the alternative midperiod examination instead of the 
reinspection required by Sec. 126.510 of this subpart, the OCMI will 
require reinspection of the OSV as soon as practicable. The OCMI will 
inform the owner or operator of the OSV in writing that the examination 
is not acceptable and that a reinspection is necessary. The owner, 
master, or operator shall make the vessel available for the 
reinspection at a time and place agreeable to the OCMI.

Sec. 174.250 and limited to restricted service as defined by 
Sec. 125.160 of this chapter.
    (a) Intact stability. (1) Each liftboat must be shown by design 
calculations to meet, under each condition of loading and operation 
afloat, the following requirements:
    (i) Those imposed by Sec. 174.045, given a ``K'' value of at least 
1.4.
    (ii) A range of positive stability of at least 10 degrees extending 
from the angle of the first intercept of the curves of righting moment 
and wind healing moment, either to the angle of the second intercept of 
those curves or to the angle of heel at which downflooding would occur, 
whichever angle is less.
    (iii) A residual righting energy of at least 5 foot-degrees between 
the angle of the first intercept of the curves of righting moment and 
wind heeling moment, either to the angle of the second intercept of 
those curves or to the angle of heel at which downflooding would occur, 
whichever angle is less.
    (2) For this section, each wind heeling moment must be calculated 
as prescribed by Sec. 174.055 of this part using winds of 60 knots for 
normal conditions of operation afloat and of 70 knots for severe-storm 
conditions of operation afloat.
    (3) For paragraph (a)(1) of this section, the initial metacentric 
height must be at least 1 foot for each leg position encountered while 
afloat including the full range of leg positions encountered while 
jacking.
    (b) Damaged stability. (1) Each liftboat must be designed so that, 
while it is in each of its normal operating conditions, its final 
equilibrium waterline will remain below the lowest edge of any opening 
through which additional flooding can occur if the liftboat is 
subjected simultaneously to--
    (i) Damage causing flooding described by paragraph (b)(4) of this 
section; and
    (ii) A wind heeling moment calculated in compliance with 
Sec. 174.055(b) using a wind speed of 50 knots.
    (2) Each liftboat must have a means of closing off each pipe, 
ventilation system, and trunk in each compartment described by 
paragraph (b)(4) of this section if any part of the pipe, ventilation 
system, or trunk is within 30 inches of the hull.
    (3) For compliance with paragraph (b)(1) of this section, no 
compartment on the liftboat may be ballasted or pumped out to 
compensate for the flooding described by paragraph (b)(4) of this 
section.
    (4) For compliance with paragraph (b)(1) of this section, each 
compartment within 30 inches of the hull, excluding the bottom of the 
liftboat, between two adjacent main watertight bulkheads and the 
uppermost continuous deck or first superstructure deck where 
superstructures are fitted must be assumed subject to simultaneous 
flooding.
    (5) In the calculations required by paragraph (b)(1) of this 
section, the 

[[Page 57674]]
permeability of a floodable space must be as listed by Table 
174.205(b).
    (c) On-bottom stability. Each liftboat must be shown by design 
calculations to exert a continuous downward force on each footing when 
the vessel is supported on the bottom with footings and is subjected to 
the forces of waves, currents, and winds of 70 knots under normal 
conditions of operation, and winds of 100 knots under severestorm 
conditions of operation when elevated in a safe place, if this place is 
other than a harbor of safe refuge. Waves and currents must be 
appropriate for the winds and place.


Sec. 174.260  Freeboard.

    (a) Each liftboat not required to obtain and maintain a loadline in 
compliance with subchapter E of this chapter must place markings on 
each side of the vessel amidships. These markings must each consist of 
a horizontal line 18 inches in length and 1 inch in height. The upper 
edges of the markings must be at a distance equal to the authorized 
freeboard measured vertically below the intersection of the 
continuation outwards of the upper surface of the weather deck and the 
outer surface of the shell. This distance must be at least 24 inches.
    (b) The markings required by paragraph (a) of this section may not 
be submerged in any condition of loading or operation.
