Offshore Supply Vessels of at Least 6,000 GT ITC

AGENCY: Coast Guard, DHS.

ACTION: Interim rule with request for comments.

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

SUMMARY: The Coast Guard Authorization Act of 2010 (the Act) removed 
the statutory size limit previously placed on offshore supply vessels 
(OSVs), and required the Coast Guard to issue regulations to mitigate 
the risk created as a result, noting the need ``to ensure the safe 
carriage of oil, hazardous substances, and individuals in addition to 
the crew'' on OSVs exceeding the previous size limit. In accordance 
with the Act, the Coast Guard is issuing this interim rule to ensure 
the safe carriage of oil, hazardous substances, and individuals other 
than crew by requiring U.S.-flagged OSVs of at least 6,000 gross 
tonnage as measured under the Convention Measurement System to comply 
with existing regulatory requirements and international standards for 
design, engineering, construction, operations and manning, inspections, 
and certification. This rule also will affect any vessel of at least 
500 gross register tons as measured under the Regulatory Measurement 
System, if that vessel is not assigned a measurement under the 
Convention Measurement System and the owner desires to have the vessel 
certificated as an OSV. The Coast Guard intends to finalize this 
interim rule after considering, and incorporating to the extent 
appropriate, any comments from the public.

DATES: This interim rule is effective August 18, 2014. Comments on this 
interim rule must be submitted to the online docket or received by the 
Docket Management Facility by November 17, 2014. The Director of the 
Federal Register has approved the incorporation by reference of certain 
publications listed in this rule, effective August 18, 2014.

III. Executive Summary

A. Purpose and Authority

    In late 2010, Congress removed the statutory size limit on offshore 
supply vessels (OSVs) and directed the Coast Guard to issue regulations 
``to ensure the safe carriage of oil, hazardous substances, and 
individuals in addition to the crew'' on OSVs exceeding the previous 
size limit, taking ``into consideration the characteristics of offshore 
supply vessels, their methods of operation, and their service in 
support of exploration, exploitation, or production of offshore mineral 
or energy resources.'' As is explained below, developments in the U.S. 
offshore industry created demand for larger OSVs than previously were 
allowed, and safely increasing the size of OSVs requires modifications 
to existing OSV regulations in order to address hazards associated with 
larger vessels carrying more cargo and personnel. Accordingly, the 
Coast Guard developed this interim rule to address safety and 
environmental hazards associated with larger OSVs. This interim rule is 
authorized and required by section 617 of the Coast Guard Authorization 
Act of 2010 (Pub. L. 111-281) (the Act).

B. Overview of Rule

    This interim rule only implements requirements for OSVs that exceed 
the pre-Act size limit for OSVs and are contracted for after the 
effective date of this rule (referred to in this document as ``large 
OSVs''). It does not affect OSVs that predate this rule or that do not 
meet the size threshold that defines large OSVs. In addition to 
carrying out statutory requirements explicitly noted in section 617 of 
the Act, such as statutory requirements for manning and oil spill 
protection, this rule addresses Congress' direction to meet safety 
needs by establishing design and operation standards for large OSVs. To 
develop these standards, the Coast Guard first evaluated existing 
requirements for OSVs (contained in 46 CFR subchapter L) to determine 
whether they were adequate for ensuring safety on the new, larger OSVs. 
Where not sufficient, the Coast Guard then used existing international 
standards that these large OSVs are highly likely to meet in order to 
compete on the international marketplace. For example, this rule 
requires large OSVs to hold certain international certificates, 
including Convention for the Safety of Life at Sea, 1974, as amended 
(SOLAS) and Convention for the Prevention of Pollution from Ships 
(MARPOL 73/78)

[[Page 48896]]

certificates, even if the OSV is certificated to operate only in U.S. 
waters. As discussed in more detail below, the safety requirements in 
these international standards align with the increased risk associated 
with large OSVs' capacity to carry cargo and passengers, and we also 
consider it very likely that large OSVs will comply with these 
international standards in order to engage in international commerce. 
Where needed, the Coast Guard used other, existing domestic standards 
for tank vessels and cargo vessels of similar size as these new, larger 
OSVs. For example, this rule requires that large OSVs meet the marine 
engineering requirements of 46 CFR subchapter F and the electrical 
engineering requirements of 46 CFR subchapter J, without the exceptions 
made for other OSVs, because of the increased capacity of large OSVs 
and the corresponding increase in the potential consequences of an 
incident involving a large OSV. Large OSVs require increased capacity 
to carry larger volumes of oil-based materials and hazardous materials, 
such as noxious liquid substances (NLS) used in drilling muds, which 
increases the risk to the environment if spilled. Existing OSV 
standards do not account for conditions found further offshore, such as 
larger and higher wave amplitude, or the capacity to carry more 
personnel. The additional requirements for large OSVs address safe 
operations in these conditions, with more cargo and more personnel.
    This rule allows a large OSV to carry more than 36 offshore workers 
if the OSV meets stability, marine engineering, fire protection, and 
lifesaving provisions set forth in this interim rule. Large OSVs are 
capable of carrying more than the 36 offshore workers previously 
allowed and conducting operations requiring more workers, and this 
interim rule implements safety provisions intended to address the risk 
associated with carrying more personnel.

C. Costs and Benefits

    This rule is not economically significant. We anticipate this rule 
will not result in additional costs to industry or government. Because 
of the previous size limit on OSVs, there currently are no U.S.-flagged 
vessels of at least 6,000 GT ITC or 500 GRT operating as OSVs and 
certificated under subchapter L requirements. Consequently, this rule 
will not directly impact any existing population of U.S.-flagged 
vessels.
    Furthermore, the interim rule is based upon existing regulatory and 
technical standards from Titles 33 and 46 of the Code of Federal 
Regulations (CFR). Where existing regulations and technical standards 
do not account for the scale of operations of large OSVs, the Coast 
Guard supplemented them with standards from the International Maritime 
Organization (IMO) Conventions, and industry consensus engineering 
standards.
    Owners and operators would comply with these standards even in the 
absence of this rule, in order to compete for international work. 
Therefore, no additional costs will be incurred by industry in the 
construction and the operation of a large U.S.-flagged OSV.
    In addition to fulfilling Congressional direction to issue 
regulations ``to ensure the safe carriage of oil, hazardous substances, 
and individuals in addition to the crew,'' the interim rule will 
standardize regulatory oversight by the Coast Guard. This is expected 
to reduce the time necessary for the approval process since standards 
will be transparent in regulation, which will lead to unquantifiable 
cost savings to both industry and government.
    Additionally, the OSVs to which this interim rule applies can carry 
a large quantity of oil and hazardous material, as well as large 
numbers of persons on board. In comparison to OSVs of less than 6,000 
GT ITC, these large vessels have decreased maneuverability and 
responsiveness due to the vessels' increased tonnage and length. These 
vessels operate in a high-risk environment near offshore units and 
other vessels, and a collision between a large OSV and an offshore unit 
or another vessel could result in a significant disaster. This interim 
rule provides a set of standards consistent with the risks and 
consequences of large OSVs. The costs and benefits of this rule are 
discussed in Section VIII.A. below and in the regulatory analysis 
available in the docket.

IV. Regulatory History

    The Coast Guard is issuing this interim rule without prior notice 
and opportunity to comment pursuant to section 617(f) of the Act, which 
directs the Secretary of the department in which the Coast Guard is 
operating to issue an interim rule ``as soon as is practicable and 
without regard to the provisions of chapters 5 and 6 of title 5, United 
States Code.'' By the same authority, the Coast Guard is making this 
interim rule effective immediately upon publication.
    Although this interim rule is effective immediately, we invite 
public comments on it. We will consider public comments when developing 
a final rule that will supersede this interim rule, and we may make 
changes in response to public comments on any part of this interim 
rule.
    In addition to revisions authorized by the Act, this rule makes a 
limited number of administrative changes to improve the readability and 
organization of the revised parts. These administrative changes include 
the standardization of tonnage acronyms, the insertion of clarifying 
language that was not necessary prior to this rule, the reorganization 
of several parts to accommodate new language, and the replacement of 
some terms with their functional equivalents. These administrative 
changes only clarify existing text and the distinction between tonnage-
based requirements in place before and after the Act: they make no 
substantive change to regulatory requirements. Therefore, the Coast 
Guard finds good cause exists under 5 U.S.C. 553(b)(B) for forgoing a 
notice of proposed rulemaking with respect to these administrative 
changes, because the changes will have no substantive effect on the 
public, and notice and comment are therefore unnecessary. For the same 
reasons, the Coast Guard finds good cause under 5. U.S.C. 553(d)(3) to 
make these administrative changes effective fewer than 30 days after 
publication in the Federal Register.

V. Basis and Purpose

    As defined by statute, an OSV is a motor vessel that regularly 
carries goods, supplies, individuals in addition to the crew, or 
equipment in support of exploration, exploitation, or production of 
offshore mineral or energy resources (46 U.S.C. 2101(19)). OSVs may 
support the construction of offshore energy facilities, or may 
transport supplies and personnel to and from these facilities. OSVs 
carry offshore goods and supplies, handle anchors and mooring 
equipment, deliver excess fuel oil to oil production facilities, and 
perform other support functions.
    Until recently, statute limited the size of OSVs to less than 500 
gross register tons (GRT) as measured under 46 U.S.C 14502, or an 
alternate tonnage established as 6,000 gross tonnage as measured under 
46 U.S.C. 14302 (GT ITC) (for background on the 6,000 GT ITC limit, 
see: 46 U.S.C. 14104 and 14302; 61 FR 66613, December 18, 1996; and 76 
FR 77129, December 12, 2011). Because of the statutory size limit on 
OSVs, OSV regulations developed prior to the publication of this 
interim rule--referred to in this preamble as ``pre-2014'' 
regulations--contemplated smaller vessels making short trips and 
capable of carrying only limited amounts of cargo and numbers of

[[Page 48897]]

people. Therefore, those pre-2014 regulations for OSVs differ from 
regulations put in place for other, larger types of vessels.
    The U.S. offshore industry has become more complex over time, 
however, creating a demand for larger, multi-purpose OSVs capable of 
operating at greater distances from shore and for more extended 
periods, using more advanced propulsion or machinery systems and 
carrying more cargo and more people on board. In response, Congress 
removed the size limit on OSVs (see section 617(a) of the Act) and made 
other statutory changes to effectively create a subgroup of OSVs 
distinguished by a tonnage assignment of at least 6,000 GT ITC (large 
OSVs). For example, the Act made it possible for large OSVs to be 
considered tank vessels (see section 617(a)(1)(B) of the Act) even 
though OSVs of less than 500 GRT or 6,000 GT ITC are deemed not to be 
tank vessels, and it specified oil fuel tank protection requirements 
for OSVs of at least 6,000 GT ITC (see section 617(e) of the Act). The 
Act also specified the number and qualifications of crew for large 
OSVs, and specified the division of watches (see sections 617(b), (c), 
and (d) of the Act).
    As noted, the Coast Guard's pre-2014 OSV regulations were developed 
for smaller vessels conducting limited operations. Removing the cap on 
the size of OSVs requires additions to pre-2014 OSV regulations in 
order to address hazards associated with larger vessels carrying more 
cargo and personnel. Accordingly, Congress directed the Coast Guard to 
issue regulations to implement the Act with respect to OSVs of at least 
6,000 GT ITC and ``to ensure the safe carriage of oil, hazardous 
substances, and individuals in addition to the crew on such vessels'' 
(section 617(f) of the Act). Congress also directed the Coast Guard to 
``take into consideration the characteristics of OSVs, their methods of 
operation, and their service in support of exploration, exploitation, 
or production of offshore mineral or energy resources'' when developing 
these regulations (section 617(f) of the Act).
    In developing this interim rule, the Coast Guard has provided 
necessary standards for the safe design, manning, and operation of 
large OSVs. In some cases, this has required additional regulatory text 
to maintain the distinction between pre-2014 regulations that may apply 
to some or all OSVs, and regulations implemented by this interim rule 
solely for large OSVs. After this rule is finalized, the Coast Guard 
may initiate a separate, broader rulemaking to address issues common to 
OSVs of all sizes.

VI. Discussion of the Interim Rule

    This rule implements requirements for OSVs of at least 6,000 GT ITC 
and, as explained below, may affect OSVs of at least 500 GRT that are 
not assigned a GT ITC. Because of the previous size limit on OSVs, 
there were no U.S.-flagged vessels of at least 6,000 GT ITC or 500 GRT 
operating as OSVs when the Act was promulgated, and this rule only 
applies to vessels contracted for or keels of which were laid after the 
date of publication. Consequently, this rule will not directly impact 
any existing population of U.S.-flagged vessels. The Coast Guard has 
issued certificates of inspection for two vessels already delivered 
pursuant to the interim certification provisions found in section 
617(f)(3) of the Act, and we are aware that industry is considering 
others. It is possible that owners of existing cargo vessels may seek 
certification of these vessels as OSVs now that the statutory size 
limit is removed: These are provided for in new applicability language 
discussed below.
    When developing these regulations, the Coast Guard looked first to 
applying the pre-2014 OSV regulations or pre-existing regulations for 
large vessels such as cargo and tank vessels. If these were not 
appropriate for application to large OSVs because they do not account 
for the scale of operations of large OSVs, we then looked to 
international standards because these large, purpose-built OSVs are 
likely to comply with such standards in order to engage in 
international commerce. In limited cases we found international 
standards needed to be supplemented either because the standard 
required interpretation by the implementing nations, or needed 
additional minimum standards to ensure the safe carriage of oil, 
hazardous substances, and individuals in addition to the crew. In these 
limited cases, the Coast Guard supplemented the international standards 
without sacrificing the flexibility to operate internationally by using 
other international standards or existing Coast Guard guidance.
    This interim rule amends several subchapters of Title 46 of the 
CFR. Most of the amendments are located in Subchapter L, which is 
specific to OSVs and consists of Parts 125 through 134. Changes to 
Parts 125 through 134 are discussed first in the preamble below, so as 
to provide a foundation for explaining related changes located in other 
subchapters. Following the discussion of Subchapter L, the preamble to 
this rule addresses related amendments that apply to large OSVs but are 
located elsewhere in Title 46, such as in Part 111 on electrical 
systems. Changes to subchapters other than L are discussed in the order 
they appear in the CFR.

A. Amendments to 46 CFR Part 125, ``General,'' Addressing 
Applicability, and Grandfathering of Existing Vessels

    Prior to this rule, the applicability section of Subchapter L 
relied on a definition of ``offshore supply vessel (OSV)'' that limited 
the size of OSVs in keeping with the statutory authority at the time 
the section was written. As discussed above, the Act removed size 
limits for OSVs from the underlying statute. In response to that 
change, this interim rule removes the upper size limits from the 
regulatory definition of OSV, and also creates a regulatory regime for 
large OSVs without changing pre-2014 requirements for OSVs of less than 
500 GRT or 6,000 GT ITC. These actions necessitate changes to Sec.  
125.100, the applicability section of Subchapter L.
    Section 125.100 paragraphs (b) and (c), which were put in place 
prior to this interim rule and are not substantively changed by it, 
provide for grandfathering of vessels contracted for, or the keels of 
which were laid, prior to March 15, 1996, on the condition that those 
vessels completed construction and obtained a Certificate of Inspection 
(COI) within 2 years. This interim rule mimics that structure by adding 
a paragraph for grandfathering of large OSVs contracted for, or the 
keels of which were laid, prior to the date of publication of this 
interim rule, with the same condition that vessels complete 
construction and obtain a COI within 2 years.
    This grandfathering structure is intended to capture two types of 
vessels: Vessels certificated in accordance with section 617(f)(3) of 
the Act; and vessels of at least 6,000 GT ITC that the Coast Guard does 
not consider to have undergone conversion under the provisions of Sec.  
125.100(e), which has been redesignated as paragraph (g) as discussed 
later in this section. The Coast Guard expects that very few vessels 
will qualify for grandfathering under this provision, and that most 
large OSVs will comply with and be certificated under Subchapter L.
    The Coast Guard considered postponing the grandfathering date until 
3 or 6 months after the publication of the interim rule, as is common 
when implementing new date-based regulations. In this case, however, 
Congress directed the Coast Guard to implement the Act ``as soon as is

[[Page 48898]]

practicable'' and provided for an interim process by which large OSVs 
could be certificated prior to the rule's publication. Postponing the 
grandfathering date would only prolong the use of the interim process. 
Therefore, the Coast Guard decided to use the date of publication as 
the date for grandfathering provisions.
    Because of the two paragraphs added to accommodate this 
grandfathering structure for large OSVs, this interim rule redesignates 
pre-2014 paragraphs (d) and (e) as (f) and (g), respectively. Both 
paragraphs remain otherwise unchanged, except that in paragraph (g) we 
have replaced the term ``major alteration'' with ``major conversion.'' 
In the specific context of Sec.  125.100, the Coast Guard has 
consistently understood this phrase to be synonymous with ``major 
conversion,'' which is a defined term in Sec.  125.160. A review of 
past major conversion determinations conducted for OSVs since 1997 
confirmed that the Coast Guard reads ``major alteration'' in Sec.  
125.100 to mean ``major conversion,'' as that term is defined in 
Subchapter L and 46 U.S.C. 2101(14a). For these reasons, replacing 
``major alteration'' in Sec.  125.100 improves consistency and clarity, 
is an administrative change without substantive effect as discussed in 
Section IV of this preamble, and is effective upon publication.

B. Amendments to 46 CFR Part 125, ``General,'' Clarifying Tonnage 
Measurement

    This interim rule applies to OSVs of at least 6,000 GT ITC. OSVs 
assigned a tonnage of less than 6,000 GT ITC, or of less than 500 GRT 
when no GT ITC is assigned, are not covered by this interim rule; they 
remain subject to the same regulations that applied prior to the Act 
and this interim rule. This rule adds a new Sec.  125.103 called 
``Tonnage Measurement'' to clarify tonnage applicability issues with 
respect to OSVs that are assigned both a GT ITC and a GRT, as well as 
to OSVs without a GT ITC assignment that are of at least 500 GRT and 
therefore were prohibited from operating as OSVs prior to the Act.
    Under the tonnage statute at 46 U.S.C. subtitle II, part J, U.S.-
flagged vessels are assigned tonnages under one of two measurement 
systems, and in some cases vessels may be measured under both. Gross 
tonnage assigned under the system of the International Convention on 
Tonnage Measurement of Ships, 1969 (referred to in U.S. law as the 
``Convention Measurement System'') is expressed as ``GT ITC,'' whereas 
tonnage assigned under the older U.S. domestic measurement system 
(referred to in U.S. law as the ``Regulatory Measurement System'') is 
expressed as ``GRT.''
    The Act does not discuss OSVs of at least 500 GRT without a GT ITC 
assignment. Because the Act removed the upper tonnage limit on OSVs, 
however, such a vessel could be certificated as an OSV if its tonnage 
was at least 500 GRT, and it was not assigned a GT ITC. Without changes 
to the terms of Subchapter L, such a vessel might not be subject to 
many important regulations for the safe carriage of oil, hazardous 
substances, and individuals in addition to the crew. The Coast Guard 
does not believe Congress intended to create a category of OSVs not 
previously permitted and not subject to the safety regulations 
governing OSVs of the same size and conducting the same activities. 
Therefore, the new Sec.  125.103(b) provides that an OSV of at least 
500 GRT that is not assigned a GT ITC must comply with regulations for 
OSVs of at least 6,000 GT ITC. This provision does not prevent a vessel 
of at least 500 GRT from obtaining a GT ITC assignment and, if that 
assignment is less than 6,000 GT ITC, complying with regulations 
appropriate for vessels of less than 6,000 GT ITC.
    Because a vessel's GRT can be lower than its GT ITC, this rule adds 
new Sec.  125.103(a), which ensures that appropriate existing 
regulations are applied to large OSVs by providing that the GT ITC 
assignment must be used when applying tonnage-dependent regulations, 
irrespective of the vessel's GRT assignment. This requirement 
recognizes that a large OSV's increased capacity for cargo and 
personnel, and ability to operate greater distances from shore for more 
extended periods, carries the potential for higher-consequence 
incidents and a corresponding need for safety and environmental 
protection requirements. We do not believe Congress intended to permit 
OSVs of at least 6,000 GT ITC to avoid meeting safety and environmental 
protection regulations merely by shifting to the GRT system of 
measurement.
    The regulatory text added by this interim rule for large OSVs uses 
the phrasing ``6,000 GT ITC (500 GRT if GT ITC is not assigned)'' to 
ensure that the applicability of specific requirements throughout Title 
46 of the CFR is clear. The pre-2014 regulatory text, however, uses the 
term ``gross tons.'' After reviewing the history and common use of 
these provisions in the specific context of Subchapter L, we concluded 
that in each relevant instance this term refers to GRT, and that 
vessels without an assigned GRT appropriately use their GT ITC to apply 
provisions dependent on ``gross tons.'' Accordingly, we added new Sec.  
125.103(c) to clarify this. Because this provision clarifies the 
historical meaning and current use of the term ``gross tons'' in 
Subchapter L, it is an administrative change without substantive effect 
as discussed in Section IV of this preamble, does not require prior 
notice and comment, and is effective upon publication. The Coast Guard 
has initiated a separate rulemaking to standardize tonnage terms 
throughout its regulations (see ``Tonnage Regulations Amendments; 
Proposed Rule'' published at 79 FR 19420 on April 8, 2014).

C. Amendments to 46 CFR Part 125, ``General,'' Addressing Certificates

    This interim rule adds a new Sec.  125.105 requiring that large 
OSVs hold certain certificates indicating compliance with SOLAS and 
MARPOL 73/78, even if the OSV is certificated to operate only in U.S. 
waters. Specifically, large OSVs must maintain Cargo Ship Safety 
Construction and Cargo Ship Safety Equipment certificates evidencing 
that these OSVs meet the minimum standards to which cargo ships on 
international voyages are held. They also must maintain a Safety 
Management Certificate evidencing that the OSV owner or operator uses 
an approved safety management system. In addition to these SOLAS 
certificates, large OSVs must maintain International Oil Pollution 
Prevention and International Air Pollution Prevention certificates, 
which, respectively, demonstrate that the vessels have the means to 
properly dispose of oils and control emissions.
    Using these international standards for domestic voyages, rather 
than a separate set of domestic standards, will create efficiencies and 
promote a uniform standard. The cargo ship safety certificates and 
safety management certificate already are required of all U.S. vessels 
of 500 GRT or more on international voyages, including tankships and 
miscellaneous non-freight vessels certificated under Subchapters D and 
I. The pollution prevention certificates already are required of all 
vessels of more than 400 GRT in the waters of nations signatory to 
MARPOL 73/78, including the United States. We therefore anticipate that 
the owners of most large OSVs subject to this rule would seek SOLAS and 
MARPOL certificates voluntarily, either because they are required in 
U.S. waters as discussed above or because they are necessary in order 
to work overseas. We also believe that the safety requirements that 
must be met in order to obtain these

[[Page 48899]]

certificates are appropriate to ensure the safe carriage of oil, 
hazardous substances, and individuals in addition to the crew on such 
vessels.
    New Sec.  125.105 also requires large OSVs to obtain an 
International Load Line Certificate, and the Coast Guard added a 
paragraph to existing Sec.  125.140 specifying that each large OSV must 
be assigned a load line in accordance with the International Convention 
on Load Lines, 1966, as amended (ICLL). Current industry practice is to 
build and operate most OSVs to ICLL standards, and the Coast Guard 
believes that OSVs of at least 6,000 GT ITC are very likely to be built 
to ICLL standards as well. The Coast Guard believes that requiring 
international load lines, rather than a variation permitted for 
domestic vessels under 46 CFR Subchapter E, will not present a 
significant burden to the industry.
    Separately, this rule adds to existing Sec.  125.150 in order to 
align the requirements for lifesaving appliances on large OSVs with 
SOLAS. It adds new paragraph (b) requiring large OSVs, including those 
authorized to carry more than 36 offshore workers when not on an 
international voyage (see Section VI.G. below), to comply with those 
portions of 46 CFR part 199 that implement SOLAS lifesaving 
requirements designed for cargo vessels. This rule makes no substantive 
change to the existing requirement for OSVs of less than 6,000 GT ITC, 
but redesignates it as Sec.  125.150(a) and adds language to that 
paragraph clarifying the applicability.

D. Amendments to 46 CFR Part 125, ``General,'' Involving Tank 
Protection for Oil Cargoes and Oil Fuel

    The Coast Guard anticipates that OSVs of at least 6,000 GT ITC will 
carry a greater volume of liquid cargoes than OSVs to date. The Coast 
Guard believes that Congress intended to enable the carriage of larger 
volumes of these liquids so as to better serve the changing offshore 
industry. The Coast Guard also believes that the size and cargo 
capacity of OSVs of at least 6,000 GT ITC create the potential for 
significant environmental damage in the event of a spill or other 
casualty, and that appropriate design and construction requirements 
should therefore accompany this increased capacity.
    Accordingly, this interim rule provides double hull requirements 
for large OSVs carrying oil to align with other vessels of similar 
capabilities and capacities. Specifically, this rule amends Sec.  
125.110 to require that tanks authorized for carriage of cargo oil, 
including drilling fluids containing oil, comply with double hull 
requirements designed for tank vessels and found in 33 CFR 157.10d. 
Applying tank vessel double hull requirements is appropriate in light 
of the pollution risk that accompanies the large volumes of oil and 
oil-based cargoes these OSVs may carry. In Sec.  125.110, we also 
inserted a reference to new Sec.  125.125, discussed below, for other 
flammable or combustible liquids carried on large OSVs.
    In addition to protection for cargo tanks, this rule provides for 
protection of oil fuel tanks as directed by the Act. Section 617(e) of 
the Act requires that an OSV of at least 6,000 GT ITC, delivered after 
August 1, 2010, or constructed under a contract entered into after 
October 15, 2010, with an aggregate capacity of 600 cubic meters or 
more of oil fuel, must comply with Regulation 12A (``Oil Fuel Tank 
Protection'') of MARPOL Annex I, regardless of whether the OSV is 
engaged in the coastwise trade or on an international voyage. 
Regulation 12A requires vessels provide double hull protection for fuel 
oil tanks, or demonstrate compliance with an accidental oil fuel 
outflow performance standard. This rule adds a new Sec.  125.115 to 
Title 46, to meet the requirements set forth in the Act.
    Historically Coast Guard regulations have distinguished between oil 
cargoes and excess fuel oil carried by OSVs. The new Sec.  125.115 
maintains that distinction by specifying that a large OSV is not 
subject to Subchapter D of Title 46, Chapter I (``Tank Vessels'') if 
the OSV is only transferring excess fuel oil from its own fuel supply 
tanks to an offshore drilling or production facility, is in the service 
of oil exploitation, and is not a tankship as defined in Sec.  30.10-
67. This provision is in keeping with 46 U.S.C. 3702(b) as amended by 
the Act, and preserves OSVs' historical ability to transfer excess fuel 
oil without meeting tank vessel requirements. As described elsewhere in 
this preamble, however, the Coast Guard has based certain other 
requirements for large OSVs on tank vessel regulations where 
appropriate.

E. Amendments to 46 CFR Part 125, ``General,'' Addressing Carriage of 
Noxious Liquid Cargoes in Bulk

    As discussed above, the Coast Guard expects large OSVs to carry 
more, and more varied, liquid cargoes than OSVs of less than 6,000 GT 
ITC. This rule adds a new Sec.  125.125 to Title 46, to help ensure the 
safe carriage of NLS in bulk on OSVs of at least 6,000 GT ITC. Common 
NLS carried on board OSVs include drilling fluids. Drilling fluids that 
contain salt or chemicals are subject to MARPOL Annex II, which is 
implemented in the United States via the Act to Prevent Pollution from 
Ships (33 U.S.C. 1901 et seq.) and which was revised, effective 2007, 
to require vessels carrying listed NLS in bulk to comply with the 
International Code for the Construction and Equipment of Ships Carrying 
Dangerous Chemicals in Bulk (IBC Code).
    MARPOL Annex II recognizes, however, that the IBC Code is not 
appropriate for all vessels. For certain vessels, including OSVs, 
MARPOL Annex II provides that Flag Administrations may establish 
appropriate measures to minimize the uncontrolled discharge of NLS into 
the sea. For OSVs, recent amendments to MARPOL Annex II explain that 
these appropriate measures should be based on IMO Resolution A.673(16), 
which provides an alternative to the IBC Code. In 2010, the Coast Guard 
issued guidance on implementing Resolution A.673(16) for new and 
existing OSVs (CG-522 Policy Letter 09-01, Rev. 1, April 5, 2010) (due 
to reorganization, CG-522 has been redesignated CG-OES). The new Sec.  
125.125 integrates some of this guidance in regulation. It allows a 
large OSV to carry NLS in bulk in its integral and fixed independent 
tanks if the OSV holds either a valid Certificate of Fitness or a valid 
International Pollution Prevention Certificate for the carriage of NLS 
in bulk, issued pursuant to regulations implementing Resolution 
A.673(16) at Sec.  125.125(b) through (f).
    Of the paragraphs implementing Coast Guard guidance on Resolution 
A.673(16), paragraphs (b) and (c) describe the types of NLS a large OSV 
may carry, and the methods and conditions required for carriage. 
Paragraphs (d) and (e) address the required Cargo Record book, 
Shipboard Marine Pollution Emergency Plan, and Procedures and 
Arrangements Manual. These documents already are required under MARPOL 
Annex II, 33 CFR part 151, and 46 CFR part 153, but the new Sec.  
125.125 permits the Procedures and Arrangements Manual to depart from 
requirements found in MARPOL Annex II, Appendix 4, in the same ways 
provided in the Coast Guard guidance on Resolution A.673(16). 
Paragraphs (f) and (g) set forth requirements for transferring NLS to 
and from a portable tank, which is otherwise authorized only by an 
endorsement on the vessel's COI.
    Although Sec.  125.120 already addresses the carriage of NLS for 
OSVs of less than 6,000 GT ITC, the new Sec.  125.125 incorporates 
recent amendments to MARPOL Annex II and recent guidance

[[Page 48900]]

issued specifically for OSVs. Implementing the Coast Guard's existing 
guidance on Resolution A.673(16) creates flexibility for large OSVs and 
facilitates operating overseas where they might otherwise be deemed to 
be in violation of MARPOL Annex II.
    Finally, this rule clarifies that pre-2014 Sec.  125.120 applies 
only to the carriage of NLS in bulk by OSVs of less than 6,000 GT ITC.

F. Amendments to 46 CFR Part 125, ``General,'' Affecting Definitions

    This interim rule revises the definition of ``offshore supply 
vessel'' in Sec.  125.160 in accordance with the Act, by removing the 
upper size limits previously placed on OSVs. Under the revised 
definition, an OSV is defined by its propulsion method and activities, 
and is more than 15 gross tons. The interim rule also adds definitions 
of ``gross register tons (GRT)'' and ``gross tonnage ITC (GT ITC)'' as 
these terms are explained above. Adding these terms is necessary in 
order to insert regulations specific to OSVs of at least 6,000 GT ITC, 
and to clarify the applicability of regulations to OSVs of at least 500 
GRT if GT ITC is not assigned.
    This interim rule does not affect the definition of liftboats. As 
discussed later in this preamble, however, this interim rule requires 
special approval of liftboats of at least 6,000 GT ITC.

G. Amendments to 46 CFR Parts 126, ``Inspection and Certification,'' 
and 127, ``Construction and Arrangements,'' Addressing Carriage of More 
Than 36 Offshore Workers

    OSVs carry personnel who work on, and in support of, offshore 
energy facilities. Under pre-2014 regulations, OSVs could carry a 
maximum of 36 offshore workers when not on an international voyage. 
Removing the size limit on OSVs makes it possible for them to carry 
more personnel, which is consistent with operations occurring farther 
offshore as well as with more labor-intensive operations such as 
platform and subsea construction. In order to safely carry more 
personnel, however, OSVs must be designed and built to standards that 
provide an adequate level of safety with respect to stability, marine 
engineering, fire protection, and lifesaving considerations, and 
personnel must be properly prepared to react to incidents such as fires 
or collisions. This is because the larger number of people on board 
increases the potential loss of life in the event of an incident. As we 
discussed in our February 2012 request for comments on accommodation 
vessels (77 FR 5039), the level of sea-going experience and vessel 
familiarity may vary widely among those working offshore, and some 
personnel could be expected to behave like passengers in an emergency. 
We therefore look to design standards to provide an adequate level of 
protection for offshore workers on large OSVs. The desired standard 
should be flexible enough to be scaled according to the potential 
consequence presented by the vessels' operational profile. After 
considering several possible standards, including domestic and SOLAS 
standards for passenger, cargo, and industrial vessels, the Coast Guard 
concluded no acceptable option existed that addressed the appropriate 
level of safety while maintaining the operational flexibility expected 
by the offshore industry.
    One of the standards the Coast Guard considered, but did not adopt, 
was the IMO Code of Safety for Special Purpose Ships (SPS Code). The 
SPS Code is an international standard for specialized vessels that 
carry personnel who are specifically needed for the particular 
operational duties of the ship and are carried in addition to those 
persons required for normal navigation, engineering and maintenance of 
the ship. Such personnel might include remotely operated vehicle 
operators, anchor handling personnel, and other workers who are not 
part of the navigational crew but who are necessary to the vessel's 
mission. The SPS Code specifically contemplates that, because of the 
nature of their work, these personnel are physically able and trained 
in safety procedures, and therefore do not require the more stringent 
protection that would be provided for a member of the general public on 
a passenger ship of similar capacity. The design requirements set forth 
in the SPS Code scale according to the number of personnel carried, 
such that the standards for a vessel carrying 60 or fewer people are 
less stringent than for a vessel carrying between 61 and 240 people. In 
this way, the SPS Code provides flexibility for the many different 
types and operational duties of vessels like large OSVs. The SPS Code 
states, however, that it is not intended for ships transporting or 
accommodating personnel other than those working on board. Given the 
nature of the work these large OSVs are likely to pursue, we anticipate 
that many, but not all, personnel on board would normally be working on 
board; some may simply be transported to offshore work sites. 
Therefore, directly adopting the SPS Code would not be appropriate.
    Instead, this interim rule adds new Subpart F to Part 127 and 
removes the constraint in existing Sec.  126.170 to allow an OSV of at 
least 6,000 GT ITC to carry more than 36 offshore workers if the vessel 
meets the new construction standard set forth there. The new Subpart F 
aligns closely with the approach of the SPS Code, and takes the similar 
position that vessels carrying few offshore workers may meet a cargo 
vessel standard, while vessels authorized to carry large numbers of 
offshore workers must meet a passenger vessel standard. The interim 
rule sets thresholds such that vessels carrying fewer than 36 offshore 
workers meet cargo vessel standards, while vessels authorized to carry 
more than 240 total persons on board must meet a passenger vessel 
standard. The bases for these thresholds change from number of offshore 
workers to total persons on board to align with both pre-2014 
regulations (36 offshore workers) and an internationally recognized 
value (240 total persons). Vessels authorized to carry at least 36 
offshore workers but no more than 240 total persons are required to 
meet a hybrid set of requirements balanced between passenger and cargo 
standards. In each of these cases, the selected standard is based upon 
SOLAS rather than other domestic regulations, in keeping with the 
widespread use of SOLAS in other portions of this rule. This is 
intended to be more efficient, minimizing the number of references to 
other sources. Furthermore, as noted elsewhere, given the international 
nature of work for large OSVs, it is the Coast Guard's assessment that 
they would voluntarily comply with these international requirements 
even in the absence of this regulation.
    The SPS Code permits a reduced amount of primary lifesaving 
equipment (lifeboats) when the vessel meets the stricter passenger 
vessel fire-protection provisions. On passenger vessels, critical 
safety systems are designed such that they will remain operational for 
the evacuation and discharge of the passengers for a relatively long 
period of time--at least 3 hours. This permits a reduction in the 
overall redundancy of the lifesaving systems. However, the operating 
environment for large OSVs exposes them to hazards not commonly 
encountered by passenger vessels and a similar reduction in redundancy, 
or the lesser protection provided by liferafts instead of lifeboats, is 
not justified on large OSVs. Therefore, this interim rule requires the 
lifesaving equipment for large OSVs to comply with SOLAS cargo vessel 
standards, and does not allow the reductions that may be permitted for 
passenger or special purpose ships.
    Because of the operational practices described above, the Coast 
Guard

[[Page 48901]]

believes that the majority of personnel on an OSV of at least 6,000 GT 
will work on board the vessel, operating specialized equipment and 
performing functions such as anchor handling, diving operations and 
support, well stimulation, and ROV operations and support. Existing 46 
CFR 15.1105 requires that any person assigned shipboard duties must 
receive basic training in accordance with the International Convention 
on Standards of Training, Certification and Watchkeeping for Seafarers 
(STCW). In addition, Subchapter L places requirements for safety 
orientation, drills, and training on offshore workers in Sec. Sec.  
131.320, 131.530, and 131.535. Further, Sec.  131.420 requires enough 
trained persons aboard each survival craft to muster and assist 
untrained persons.
    However, notwithstanding these existing Subchapter L operations 
requirements for drills and training of offshore workers, the Coast 
Guard is considering appropriate standards for vessels providing 
accommodation service (i.e., the supply of hotel-like services such as 
dining, berthing, and access to recreational facilities) for personnel 
who are not engaged in work aboard the vessel but are engaged in work 
on a nearby drilling or production platform on the U.S. Outer 
Continental Shelf (OCS). (See 77 FR 5039, February 1, 2012). In the 
future, we may consider additional training requirements for personnel 
who are not members of the crew and possibly other additional safety 
standards for vessels that engage in accommodation service.

H. Amendments to 46 CFR Part 127, ``Construction and Arrangements''

    This interim rule adds a new Sec.  127.200 to Title 46, specifying 
that OSVs of at least 6,000 GT ITC must be classed by an authorized 
classification society recognized under the provisions of 46 CFR part 
8. Classification societies ensure that the vessel is built to and 
complies with a set of design and construction standards. Meeting 
classification society requirements is consistent with SOLAS Chapter 
II-1, Regulation 3-1, and we expect that all large OSVs would be 
classified even if not required by this rule. Requiring the use of an 
authorized classification society, however, ensures that the 
classification society requirements are developed by an organization 
with adequate resources and experience.
    This interim rule adds a new Sec.  127.225 setting forth structural 
fire-protection standards based on SOLAS requirements for cargo ships 
and existing U.S. regulations for tank vessels. SOLAS provides fire-
protection standards requiring the use of non-combustible materials 
(Method IC), but as an alternative allows the use of sprinklers or 
smoke detectors. The Coast Guard's longstanding view, as established by 
regulation, is that the use of these alternatives in lieu of non-
combustible materials does not provide an adequate level of safety, and 
the Coast Guard has advocated that non-combustible construction is 
superior to reliance on sprinklers or smoke detectors since the fire on 
board the cruise vessel Morro Castle on September 8, 1934, which caused 
the deaths of 137 persons. The requirement in Sec.  127.225(a) limits 
the options available to large OSVs to Method IC construction and is 
consistent with existing U.S. regulations for other large vessels 
(e.g., 46 CFR subchapters D, H, and I). Section 127.225 also provides 
for approval of materials under current U.S. regulations, and applies 
fire-protection standards based on standards applicable to tank 
vessels. These provisions for large OSVs are in addition to the general 
fire-protection provisions for all OSVs at Sec.  127.220.
    Existing Sec.  127.230 requires OSVs to comply with special 
stability requirements found in 46 CFR subchapter S, but large OSVs 
must meet different stability requirements in order to obtain the SOLAS 
certificates required in Sec.  125.105 and necessary to compete in the 
international market. To avoid duplication between the two sets of 
requirements, this rule adds a new paragraph (b) to existing Sec.  
127.230 to exempt large OSVs from the domestic stability requirements. 
Because there is no SOLAS damage stability requirement for cargo ships 
less than 80 meters in length, we limited this exemption to large OSVs 
of 80 meters or more in length. OSVs that are less than 80 meters in 
length would continue to comply with the stability requirements in 46 
CFR Subchapter S. Exempted large OSVs may choose to meet the 
requirements in Subchapter S, so long as they also demonstrate 
compliance with the SOLAS stability requirements.

I. Amendments to 46 CFR Part 128, ``Marine Engineering: Equipment and 
Systems''

    Existing Part 128 requires OSVs to comply with Subchapter F of 
Title 46, Chapter I, titled ``Marine Engineering,'' but lists a number 
of exceptions specific to OSVs, such as allowing certain piping systems 
to meet less restrictive standards than those found in Subchapter F. 
This interim rule makes no change to the requirements for OSVs of less 
than 6,000 GT ITC, but it does not extend those same exceptions to 
large OSVs. To accomplish these changes, this rule amends 46 CFR 
128.110 by redesignating existing paragraph (b) as (c), without 
otherwise changing it, and inserting a new paragraph (b) requiring 
large OSVs to meet Subchapter F. It also makes minor conforming changes 
to paragraph (a) to make clear that the pre-2014 provision of Part 128 
continues to apply to OSVs of less than 6,000 GT ITC, without change.
    The requirement to meet all of Subchapter F is the same as that for 
cargo vessels under Subchapter I, and is appropriate for large vessels. 
As a result of this requirement, pre-2014 exemptions in Part 128 do not 
apply to large OSVs. In particular, this interim rule clarifies that 
the fuel requirements for large OSVs should follow Subchapter F. To 
accomplish this, the interim rule specifies that pre-2014 text of Sec.  
128.310 applies to OSVs of less than 6,000 GT ITC, and then adds 
provisions for large OSVs. The new provisions require that internal 
combustion engines installed on large OSVs use fuel having a flashpoint 
of at least 60[deg] C (140[deg] F). This requirement differs from the 
rule for OSVs of less than 6,000 GT ITC, which requires fuel with a 
flashpoint of at least 43[deg] C (110[deg] F), but it aligns with the 
provisions of Subchapter F (see 46 CFR 58.01-10) and the requirements 
found in SOLAS (see Chapter II-2, Part B). Using fuel with a higher 
flashpoint is safer as well as consistent with SOLAS requirements for 
travelling internationally, as is likely for these OSVs. The new 
provisions of Sec.  128.310 do allow fuels with a lower flashpoint to 
be used on gasoline-powered rescue boats and emergency generators, or 
elsewhere with the Coast Guard's specific approval.

J. Amendments to 46 CFR Part 129, ``Electrical Installations''

    Existing Part 129 requires OSVs to comply with Subchapter J of 
Title 46, Chapter I, titled ``Electrical Engineering,'' but lists a 
number of exceptions specific to OSVs. This interim rule makes no 
substantive change to these limited requirements for OSVs of less than 
6,000 GT ITC, but it does not extend those same exceptions to large 
OSVs.
    Because of the size and types of operation systems that will be 
found onboard these large OSVs, the interim rule requires large OSVs to 
meet all of Subchapter J, aligning it with requirements imposed on 
similar cargo vessels under Subchapter I. For example, unlike OSVs of 
less than 6,000 GT ITC, large OSVs must meet the

[[Page 48902]]

requirements of 46 CFR 111.10-7, which mandates electrical services 
necessary to start the main propulsion plant from a dead ship 
condition. Large OSVs must also meet 46 CFR subpart 112.20, Emergency 
Systems Having a Temporary and a Final Emergency Power Source, which 
requires an emergency power source and certain transfers of emergency 
loads.
    To accomplish this change, this rule amends Sec.  129.110 by 
redesignating the existing text as paragraph (b), and adding a new 
paragraph (a). This rule also makes a conforming change to Sec.  
129.315(a) so that the section remains limited to OSVs of less than 
6,000 GT ITC, as was the case before the Act removed the size limits on 
OSVs.
    This interim rule also adds new Sec.  129.570 to require that cargo 
oil tanks on large OSVs be equipped with alarms to prevent oil spills 
during cargo transfer. The alarms are intended to alert operators when 
a cargo oil tank is becoming full, and again when tank overflow is 
imminent. The new Sec.  129.570 is based on existing regulations for 
tankships and is appropriate for large OSVs because of the volume of 
oil these OSVs may carry.

K. Amendments to 46 CFR Part 130, ``Vessel Control''

    To avoid contradictory requirements between existing Part 130 and 
new marine engineering requirements for large OSVs, this rule makes 
conforming changes to portions of Part 130 that previously had applied 
to OSVs of 100 gross tons or more. Specifically, it modifies Sec. Sec.  
130.140 and 130.400 with the phrase, ``Except as provided in Sec.  
128.110.'' Section 128.110 directs large OSVs to comply with Subchapter 
F, as discussed above, and therefore this language prevents large OSVs 
from using Sec. Sec.  130.140 and 130.400 in lieu of Subchapter F. This 
rule does not change the requirements already found in those sections 
for OSVs that are of 100 gross tons or more, but less than 500 GRT or 
6,000 GT ITC.

L. Amendments to 46 CFR Part 131, ``Operations,'' Addressing Vessel 
Maneuvering

    This interim rule adds new 46 CFR 131.990, which requires that 
certain information about the OSV's maneuvering capabilities must be 
displayed in the pilothouse for the use of vessel operators and pilots. 
The information includes the time and distance necessary to stop the 
OSV, and a warning about conditions that may alter the information 
provided. Section 131.990 matches existing provisions that already 
apply to other vessels of 1,600 gross tons or more, including cargo 
vessels regulated under Subchapter I.

M. Amendments to 46 CFR Part 132, ``Fire-Protection Equipment''

    This interim rule makes changes in Part 132 to address certain 
areas not covered by SOLAS chapter II-2. Section 125.105 requires large 
OSVs to comply with the SOLAS rules for cargo ships, including the 
chapter II-2 fire-protection rules, but there are three areas where the 
SOLAS rules do not include specific criteria for the approval of 
equipment. This interim rule therefore adds three new sections to 
clearly state the applicable U.S. requirements for: Fire pumps, fire 
hoses, and nozzles (see new paragraph (d) in Sec.  132.100); portable 
and semiportable fire extinguishers (see new Sec.  132.200); and 
firefighter's protective clothing and personal safety equipment (see 
new Sec.  132.365). The fire extinguishers and protective equipment 
required by these new sections are the same as required on tankships. 
These requirements are in addition to the pre-2014 fire-protection 
requirements of Part 132, which continue to apply to other OSVs without 
change as reiterated in Sec.  132.200(a). Requiring large OSVs to carry 
fire-protection equipment similar to that on tankships reflects the 
increased quantities of oil and other flammable liquids these large 
OSVs may carry.
    For the same reasons, this rule adds new Sec.  132.390 to ensure an 
adequate level of fire protection for the greater quantities of 
flammable or combustible liquids expected to be carried on large OSVs. 
Except for OSVs fitted with a deck foam system, all large OSVs must 
carry at least two 135-kg semi-portable dry chemical fire extinguishers 
to mitigate the fire risk associated with a spill on the weather deck. 
A deck foam system is necessary on large OSVs carrying larger 
quantities of certain flammable and combustible liquids to address the 
greater fire risk presented by these quantities. Therefore, for large 
OSVs that carry 3,000 cubic meters or more of flammable or combustible 
liquids with a flashpoint of 60 [deg]C (140[emsp14][deg]F) or below in 
fixed tanks, this interim rule requires cargo area and cargo-pump room 
fire-extinguishing systems similar to those required on tank vessels. 
OSVs with this cargo carrying capacity must have a deck foam system 
designed to tankship standards where the cargo tanks extend vertically 
to the weather deck. The requirement to provide foam coverage for the 
total deck area is intended to mitigate the fire risk associated with 
spills taking into consideration the additional potential hazard of 
cargo tank physical damage (e.g., explosion, dropped load) as well as 
the possibility of spills from associated deck fittings such as pumps, 
valves, and vents. If the cargo is carried in double bottom or other 
tanks that do not extend to the weather deck, the foam system is only 
required to protect weather deck areas within 10 feet (3 m) of 
potential leak sources such as manifolds and vents, since it is 
considered that in these cases the possibility of a large volume spill 
covering the entire deck is less likely.
    These OSVs also are required to have a fixed total flooding gas 
fire extinguishing system designed to tankship standards for the 
protection of any accessible below-deck cargo pump rooms or other 
enclosed spaces that contain tank openings, pumps, flanges, valves, 
loading manifolds, or other potential sources of leakage. The 
regulation refers to accessible below-deck spaces because it is not 
intended to require extinguishing systems in spaces not easily accessed 
by the crew, such as cofferdams, where such leak points are unlikely to 
be present.
    Review of currently operating OSVs complying with Subchapter L 
revealed that the great majority carry less than 3,000 cubic meters of 
flammable or combustible liquids as cargo. To address the greater fire 
risk presented by the carriage of larger quantities of flammable or 
combustible liquids by larger OSVs, this interim rule requires 
additional fire-protection measures compared to current Subchapter L 
when volumes greater than 3,000 cubic meters of flammable or 
combustible liquids are carried.

N. Amendments to 46 CFR Part 134, ``Added Provisions for Liftboats''

    A liftboat is a subtype of OSV that has movable legs. The legs, 
when resting on the sea floor, raise the hull above the sea to create a 
platform from which work can be performed on another offshore 
structure. Most liftboats are relatively small--usually less than 1,000 
GT ITC--but the Coast Guard is aware of larger liftboats operating 
overseas, and of some limited interest in developing U.S.-flagged 
liftboats of at least 6,000 GT ITC.
    The safe construction and operation of liftboats requires 
consideration of unique factors, including leg strength and stability, 
sea floor stability, vulnerability to wind, height of the hull above 
the water, and the speed at which the hull is raised. The existing 
regulations in Part 134 of Subchapter L were designed to address these 
concerns but, because liftboats historically have been small, the Coast 
Guard currently lacks data with which to evaluate the

[[Page 48903]]

safety of liftboats of 6,000 GT ITC or more. The Coast Guard also does 
not believe that the purpose of the Act was to provide for extremely 
large liftboats, because liftboats are a unique type of vessel and 
generally do not undertake the cargo and personnel carriage that was 
the focus of the Act.
    Therefore, this interim rule provides that liftboats of 6,000 GT 
ITC or more are permitted only on a case-by-case basis with the 
approval of the Commandant. As the demand for and design requirements 
of large liftboats becomes clearer, the Coast Guard will consider 
developing a regulatory framework for them. We encourage the public to 
submit information about larger liftboats; in particular, we request 
information on the likelihood of liftboats reaching or exceeding 6,000 
GT ITC, and on whether large liftboats should meet the requirements of 
46 CFR subchapter I-A for mobile offshore drilling units (MODUs).

O. Amendments to 46 CFR Part 2, ``Vessel Inspections''

    In 46 CFR 2.10-25, the Coast Guard revised the definition of 
``offshore supply vessel'' by removing the upper size limit previously 
found in paragraph (3) of that definition. Removing the upper size 
limit is appropriate in light of the change made by the Act to the 
underlying statutory authority, and brings large OSVs within the 
existing Part 2 vessel inspection provisions. This rule makes no change 
to vessels of 15 or fewer gross tons. The definition of OSV otherwise 
remains unchanged, and the Coast Guard did not alter other sections of 
Part 2 that mention OSVs.
    The Coast Guard is aware of similar definitions in Parts 68 and 
175, but found that these provisions were specific to particular groups 
of OSVs and that it would be unnecessary to revise these definitions in 
order to implement the Act.

P. Amendments to 46 CFR Part 15, ``Manning Requirements''

    This rule implements manning requirements for large OSVs as 
required by the Act.
    Section 617(d) of the Act amended 46 U.S.C 8104 to permit the use 
of two watches in certain circumstances, so long as the officers and 
crew are ``in compliance with hours of service requirements (including 
recording and recordkeeping of that service) as prescribed by the 
Secretary.'' This interim rule revises 46 CFR 15.705 to reflect that 
statutory requirement, and specifies that the individuals must be in 
compliance with the work hours and rest period requirements found in 46 
CFR 15.1111. We expect that vessels subject to this rule will seek 
international certification and, as a result, be required to meet the 
STCW Convention requirements implemented in 46 CFR Part 15, Subpart K, 
including the hours of work hours and rest period requirements found in 
46 CFR 15.1111.
    Section 617(c) of the Act amended 46 U.S.C. 8301 to specify the 
minimum number of licensed individuals required aboard OSVs. It 
requires that an OSV of less than 500 GRT or 6,000 GT ITC have one 
licensed mate on a voyage of less than 600 miles, and two licensed 
mates on a voyage of at least 600 miles. It also requires that an OSV 
of at least 6,000 GT ITC have two licensed mates on a voyage of less 
than 600 miles, and three licensed mates on a voyage of at least 600 
miles. This interim rule revises 46 CFR 15.810 to reflect the statutory 
changes, while leaving in place the existing regulatory alternative for 
vessels of less than 100 gross tons. Specifically, this interim rule 
removes Sec.  15.810(b)(4), which had applied to OSVs of 100 gross tons 
or more, and redesignates Sec.  15.810(b)(5) as (b)(4). The interim 
rule then creates two new paragraphs: New paragraph (b)(5) for OSVs of 
between 100 GRT and 500 GRT or 6,000 GT ITC, and new paragraph (b)(6) 
for OSVs of at least 6,000 GT ITC (500 GRT if GT ITC is not assigned).
    These new paragraphs implement the manning requirements stated in 
the Act. The interim rule uses the term ``credentialed'' rather than 
``licensed'' because the Coast Guard now issues Merchant Mariner 
Credentials (MMCs) rather than licenses. The term ``credentialed'' 
encompasses ``licensed'' as used in the Act, and includes any licensed 
mate whose license will be replaced with an MMC after the license 
expires. We anticipate that credentialed mates will keep watch, with 
the Master and Chief Engineer occasionally standing in for high-
intensity operations or in the case of illness or fatigue. This view is 
supported by the National Offshore Safety Advisory Committee (NOSAC) 
report, ``Certifications and Standards for Large OSVs,'' dated April 
18, 2008, and available in the docket. The master is distinct from the 
mate in our existing regulations, and should not be counted as one of 
the mates required on an OSV.
    As was the case before the Act, the amended statute and the revised 
regulations require more mates for vessels on longer voyages. 
Previously, regulations had stated that a voyage includes the accrued 
distance from port of departure to port of arrival and does not include 
stops at offshore points. The Coast Guard has become aware, however, 
that some readers misinterpret this provision to restart the voyage at 
each offshore point. This is an incorrect reading of the current 
language and undermines the purpose of the regulation, which is to 
provide for more mates--and therefore, shorter watches and less 
fatigue--on long voyages, even if those voyages include visits to 
offshore points. Therefore, new Sec.  15.810(b)(6) for large OSVs 
clarifies that a voyage includes the total accrued distance between 
departing and arriving at a port.
    Although the Coast Guard's understanding of ``voyage of less than 
600 miles'' remains the same as explained above, the Coast Guard has 
chosen not to change the language in paragraph (b)(5) in this interim 
rule. Instead, the Coast Guard invites the public to submit information 
on how it measures voyages under this provision and what, if anything, 
would change as the result of a clarification similar to the one in 
paragraph (b)(6). The Coast Guard is considering inserting the 
clarification from paragraph (b)(6) into paragraph (b)(5) in the final 
rule that will follow this interim rule, and public comments will 
assist that decision.
    Based on the NOSAC report, this rule modifies 46 CFR 15.825 to 
specify that large OSVs approved for the use of automated systems must 
carry at least one assistant engineer. The Coast Guard agrees with this 
NOSAC recommendation because, as the size of the vessel increases, so 
do the engineering demands. The increased number of engineering 
components and the enhanced complexity of component technology make it 
important to keep enough personnel on board to maintain those 
components, and to respond to shipboard emergencies and equipment 
failure. For these reasons, large vessels usually carry one or more 
assistant engineers. The requirement that large OSVs carry an assistant 
engineer is only a minimum standard and the operator should provide 
additional engineers if necessary for safe vessel operation. 
Additionally, the Officer in Charge, Marine Inspection (OCMI) may 
continue to require more than one engineer under existing Sec.  
15.825(c), which has been redesignated as paragraph (d).
    The Coast Guard is aware that the Act necessitates other changes to 
regulatory requirements for mariners, including requirements in 46 CFR 
subchapter B governing mariner credentialing. We anticipate addressing 
these changes in a separate rulemaking.

[[Page 48904]]

Q. Amendments to 46 CFR Part 62, ``Vital System Automation,'' and 
Related Amendment to 46 CFR Part 61, ``Periodic Tests and Inspections''

    Most large modern vessels use automated control and monitoring 
systems to replace specific personnel or to reduce overall crew 
requirements. The Coast Guard regulates and tests automated vital 
systems to ensure that a vessel with automated systems is as safe as a 
vessel under direct manual operator supervision. Coast Guard 
regulations at 46 CFR part 62 address automation and already apply to 
tank vessels and cargo vessels over 500 GRT as well as passenger 
vessels over 100 GRT. Because of the hazards associated with larger 
vessels carrying more cargo and personnel, the automated systems 
regulations in Part 62 are appropriate for large OSVs. This interim 
rule amends the applicability section of Part 62 to include large OSVs.
    This interim rule also makes a related change to 46 CFR part 61, 
which addresses testing of vital system automation. Within the text of 
Part 61, this rule revises the last sentence of existing Sec.  61.40-
10(b) so that the Marine Safety Center, rather than Coast Guard 
Headquarters (CG-ENG) approves other test techniques. This is an 
administrative change with no substantive impact on the public and, as 
discussed in Section IV of this preamble, the Coast Guard finds good 
cause to make this change without prior notice and comment and without 
delay.

R. Amendments to 46 CFR Part 90, ``General Provisions'' for Cargo and 
Miscellaneous Vessels

    46 CFR subchapter I provides regulations for cargo and 
miscellaneous vessels. Prior to the creation of Subchapter L in the 
1990s, OSVs were regulated under Subchapters I and T. Subchapter I 
contains ``grandfathering'' language, matching that in Subchapter L, 
that distinguishes between OSVs subject to Subchapter I and OSVs 
subject to Subchapter L. (Subchapter T contains similar language, but 
is specific to vessels of less than 100 gross tons and therefore not 
affected by this rule.) This interim rule revises Sec.  90.05-20 in 
Subchapter I to conform to Sec.  125.100 by inserting provisions for 
large OSVs grandfathered under Sec.  125.100 as discussed above (i.e., 
large OSVs certificated under section 617(f)(3) of the Act and vessels 
of at least 6,000 GT ITC that have not undergone a major conversion 
under Sec.  125.100(e)). These vessels are subject to Subchapter I.
    This rule makes similar changes to the definition of OSV at Sec.  
90.10-40. The rule removes the upper size limits from paragraph (a), in 
accordance with statutory changes made by the Act. In paragraph (b), it 
adds a definition of ``existing'' large OSVs to which the 
grandfathering provisions of Sec.  90.05-20 will apply, and in 
paragraph (c), it adds a definition of ``new'' large OSVs that will be 
subject to Subchapter L.
    This interim rule also makes non-substantive changes to the 
existing language of Sec. Sec.  90.05-20 and 90.10-40 to improve 
clarity. For example, because the sections now discuss both GRT and GT 
ITC measurements, this interim rule replaces the word ``tons'' with 
``GRT'' and includes references to the appropriate definitions in 
Subchapter L. These changes do not alter the requirements previously 
applicable to OSVs of less than 500 GRT or 6,000 GT ITC. Because they 
are non-substantive administrative changes made to improve clarity, the 
Coast Guard finds that prior notice and comment is unnecessary, and 
finds good cause to make these changes effective upon publication as 
described in Section IV above.

S. Amendments to 46 CFR Part 110, ``General Provisions'' Within 
Subchapter J, ``Electrical Engineering''

    46 CFR part 110 includes the incorporation by reference and 
definitions sections for the whole of Subchapter J, including Part 111. 
Most of the changes this interim rule makes to Part 110 involve 
incorporations by reference and new definitions applicable to 
requirements found in Part 111 and discussed in detail below. The 
definitions of note in Sec.  110.15-2 are those that explain the 
hazardous location classifications used in new Subpart 111.106, which 
is specific to hazardous locations on large OSVs. As explained in the 
portion of the preamble below that discusses Subpart 111.106, this 
interim rule provides for a choice of industry standards to apply in 
hazardous locations, and each incorporated standard uses slightly 
different terms to classify hazardous locations. The definitions in 
Sec.  110.15-2 provide a standard frame of reference for readers who 
may be using any of the incorporated standards.
    This rule also adds a new paragraph (p) to Sec.  110.25-1, to 
specify requirements for submitting plans for OSVs to which new Subpart 
111.106 applies. Subpart 111.106 is discussed below. Section 110.25-
1(p) requires submission of plans that demonstrate the safe design of 
potentially hazardous locations, particularly on OSVs carrying 
flammable cargoes.

T. Amendments to 46 CFR Part 111, ``Electric Systems--General 
Requirements''

    The term ``hazardous location'' is broadly understood as an area 
where flammable gasses, vapors, liquids, or other ignitable substances 
may concentrate, resulting in a fire or explosion hazard. The Coast 
Guard regulates hazardous locations on vessels to ensure that 
electrical components are either absent from hazardous locations or, if 
they must be present, are of a type that is unlikely to cause a fire or 
explosion. Although Part 111 already contains a subpart on hazardous 
locations, the Coast Guard has added provisions specific to large OSVs 
to reflect current, widely accepted standards and to address the 
hazards posed by large vessels potentially carrying flammable 
substances and/or large numbers of people.
    This rule creates new Sec.  111.05-20 to specify that large OSVs 
designed to carry flammable or combustible liquid cargoes with closed-
cup flashpoints not exceeding 60 [deg]C (140 [deg]F), such as methanol, 
may have a grounded distribution system only if the current does not 
flow directly through any hazardous locations bounded by flammable or 
combustible liquid cargo integral storage tanks. This provision is 
intended to avoid the introduction of an electrical arc into a 
hazardous location given the provisions for use of increased quantities 
of flammable liquids on larger vessels.
    This rule also creates new Subpart 111.106, ``Hazardous Locations 
on OSVs,'' specifically for large OSVs. The Subpart provides a choice 
of standards with which electrical installations must comply when they 
cannot be placed outside hazardous locations, and testing and 
certification requirements appropriate to each choice. Electrical 
installations must comply with either National Electric Code (NEC) 
standards or International Electrotechnical Commission (IEC) standards, 
subject to certain testing requirements and, in the case of the IEC 
option, substitution of U.S. requirements for certain provisions of the 
international standard. This rule provides the flexibility to choose an 
internationally accepted certification system that existing Subpart 
111.105 does not provide.
    With respect to U.S. industry standards, this rule allows hazardous 
locations on large OSVs to comply with either of two classification 
systems found in the NEC, also known as National Fire Protection 
Association 70 (NFPA 70). Both of these systems classify hazardous 
locations according

[[Page 48905]]

to likely presence of flammable substances. Hazardous locations may 
comply with Articles 500 through 504 of NFPA 70, which classify areas 
into three Classes, each containing two Divisions. These Articles set 
forth requirements for the design, location, and required and 
prohibited contents for each Division. Alternatively, hazardous 
locations may comply with Article 505 of NFPA 70, which provides an 
alternative system classifying areas into Zones. NFPA 70 contains 
guidance on moving between the two systems. We use the term ``Class I, 
Special Division 1'' to describe areas within Class I, Division 1, 
under Article 501 that are equivalent to Zone 0 under Article 505. This 
term is based on the American Petroleum Institute Recommended Practice 
(API RP) 500.
    Regardless of which portion of NFPA 70 is followed, this rule 
requires that equipment be tested, and listed or certified, by an 
independent laboratory. The Coast Guard generally requires third-party 
testing for critical equipment, such as lifesaving and firefighting 
equipment, and believes that safe certification for electrical systems 
on large OSVs must include independent third-party certification. This 
requirement is consistent with other regulatory agencies' approach to 
electrical equipment in hazardous locations in other types of 
facilities, such as refineries. In accordance with NFPA 70, this rule 
provides a choice of standards against which the equipment may be 
evaluated: For the Class and Division system set forth in Article 500, 
the equipment may meet a selection of American National Standards 
Institute (ANSI), Underwriters Laboratories, FM Approvals, and Canadian 
Standards Association standards, while for the Zone system set forth in 
Article 505 the equipment may meet certain standards from the ANSI/ISA 
60079 series. Where any of these standards are used, certification 
would be performed by an independent laboratory meeting 46 CFR part 
159.\1\
---------------------------------------------------------------------------

    \1\ The authority for current 46 CFR part 159 is 46 U.S.C. 3306, 
which ``contains broad authority to prescribe regulations for proper 
inspection and certification of vessels,'' House Report No. 98-338 
(August 1, 1983), 1983 U.S.C.C.A.N. 924, 954-53, including the 
specific requirement to prescribe regulations to carry out the 
statutory requirements ``in the most effective manner,'' 46 U.S.C. 
3306(a). The Coast Guard finds the use of independent laboratories 
in the Coast Guard's approval process to be ``the most effective 
manner'' of executing and carrying out its obligations under section 
3306.
---------------------------------------------------------------------------

    As an alternative to U.S. standards, and to provide regulatory 
flexibility, this rule allows hazardous locations on large OSVs to 
comply with the widely accepted international standard IEC 60092-502, 
``Electrical installations in ships--Tankers--Special features.'' The 
Coast Guard chartered a study by ABSG Consulting to evaluate IEC 60092-
502, and the 2010 report is available in the docket. The study modeled 
gas dispersion from multiple scenarios with various vapor sources, 
cargoes, and ventilation rates, and compared it to values provided in 
the IEC standard. Overall, the study validated the IEC approach, with 
certain exceptions, because it indicated that in most cases the 
flammable vapors were well inside IEC Zone 1 areas. We therefore adopt 
the IEC 60092-502 standard in this rule with some exceptions, which are 
discussed in detail below. In general, we retained the zones defined by 
IEC 60092-502 except where the study indicated that zones defined by 
IEC 60092-502 might not be large enough, in which case we enlarged the 
zones. Where the study implied that zone sizes may be reduced, we 
retained the IEC 60092-502 zones to promote safety and compliance with 
international standards.
    The study indicated that for certain cargoes during cargo transfer, 
flammable vapors from large-volume tank vents tended to sink to the 
deck, forming a blanket extending beyond area boundaries that were 
developed based only upon distance from the vent (i.e., boundaries 
similar to existing Sec.  111.105-31(f) and IEC 60092-502 Regulation 
4.2.2.7; see page 27 of the study). This was the case whether or not 
ventilation was restricted. Based on this, we adopted the IEC 60092-502 
regulation 4.2.2.11 requirements in this area, with the exception that 
the hazardous location designation applies whether or not ventilation 
is considered to be restricted. Similarly, for large-volume tank 
outlets the study indicated that vapors tended to extend beyond the 6-
meter Zone 1 area of IEC 60092-502 Regulation 4.2.2.8, and we adopted 
an 8-meter zone to account for this. These modifications appear in new 
Sec.  111.106-9.
    The study also suggested that the use of mechanical ventilation may 
not be sufficiently effective in reducing flammable vapor concentration 
down to safe levels in certain hazardous locations (see pages 30-33 and 
53 of the study). We therefore did not adopt the portions of IEC 60092-
502 Regulation 4.1.4, Table 1, that allow enclosed spaces to be 
reclassified based upon mechanical ventilation; instead, we inserted 
new Sec. Sec.  111.106-13(b) and 111.106-15. Finally, the study 
consistently indicated the presence of ignitable vapors in the 
immediate proximity of certain vapor release point sources, a finding 
that is consistent with API RP 505 standards (see API RP 505 6.5.5). We 
therefore adopted zone 0 areas similar to those found in API RP 505.
    In some cases, the study indicated that certain Zone 1 areas may be 
reduced. For the reasons discussed above, this rule does not reduce the 
areas, but the Coast Guard is interested in receiving public comments 
on whether these zone requirements should be reduced. For example, 
because modeling indicated that gasses extended no further than 0.5 
meters above the deck, a height of 2.4 meters for Zone 1 as described 
in IEC 60092-502 Regulation 4.2.2.11 may be larger than necessary. For 
certain vapor sources where a failure (e.g., failure of a valve or 
flange) is required for vapor release, it may be reasonable to reduce 
the size of the Zone 1 hazardous location for these vapor sources. We 
welcome public comment on this topic. For other vapor sources (e.g., 
vents) where vapor is likely to be present without a failure, however, 
we do not believe it is reasonable to reduce the Zone 1 sizes.
    As with the domestic standards, electrical installations in 
compliance with IEC 60092-502 must be tested and approved or certified 
by an independent authority. For vessels designed to compete on the 
international market or built in foreign shipyards, in this rule the 
Coast Guard adopts the international certification system, IECEx 
(Certification to Standards Relating to Equipment for use in Explosive 
Atmospheres), a certification system that is based on full testing to 
the IEC 60079 series of standards. The IECEx system ensures testing of 
equipment by a competent authority other than the manufacturer. 
Approval under the IECEx system involves an Ex Certification Body 
(ExCB) and an Ex Testing Laboratory that have been accepted into the 
IECEx system after meeting competence requirements found in the 
International Organization for Standardization ISO/IEC Standard 17025 
and related IECEx procedures. The Ex Testing Laboratory tests the 
covered equipment to determine whether it meets IECEx system standards, 
and drafts an IECEx Test Report to document the test results. The ExCB 
reviews the manufacturing quality assurance process and issues an IECEx 
Quality Assessment Report. Based on these reports, the ExCB may then 
issue an IECEx Certificate of Conformity for the equipment.
    The Coast Guard considered allowing certification of electrical 
equipment under the Directive on Equipment and Protective Systems 
Intended for use in Potentially Explosive Atmospheres (94/9/EC) (``ATEX 
directive''), which is used

[[Page 48906]]

in Europe and is harmonized with the IECEx system, but chose not to do 
so because the ATEX directive does not guarantee testing by a competent 
authority other than the manufacturer. ATEX is a part of a series of 
European laws, the EC Directives, which are applicable to the European 
Economic Area member states. The ATEX directive contains Essential 
Health and Safety Requirements for products applied in hazardous areas, 
instead of restrictive references to standards. The ATEX Directive 
allows all kinds of standards to be used. When the harmonized standards 
are used, it provides the presumption of conformity with the Essential 
Health and Safety Requirements. Use of the IEC 60079 series is provided 
for already in existing Subpart 111.105; currently, when the Coast 
Guard discovers ATEX equipment or components installed on U.S. 
inspected vessels, it requires that this equipment be replaced or 
proven through testing to comply with IEC standards. In some cases, the 
laboratory that certified the equipment under the ATEX directive has 
found that additional tests are necessary to re-certify the equipment 
under the IECEx system. This demonstrates that, although these 
standards are harmonized, there is a possibility that equipment 
certified under the ATEX directives is not safe for the intended use. 
In addition, most IMO conventions for seagoing vessels refer to IEC 
series standards.
    For protections not covered by the standards discussed above, this 
interim rule incorporates existing requirements for other large 
vessels. For example, Sec.  111.106-3 contains submerged pump motor 
requirements based on existing Subpart 111.105 and tank barge 
regulations, and cargo tank separation and cargo piping requirements 
based on fire-protection provisions for tank vessels. It also 
incorporates ASTM F2876-10, ``Standard Practice for Thermal Rating and 
Installation of Internal Combustion Engine Packages for Use in 
Hazardous Locations in Marine Applications,'' to address the growing 
use of engines with electronic controls that could cause arcing or 
sparking in a hazardous area.
    This rule provides flexibility by allowing cable and wiring to 
comply with a selection of international and domestic standards. It 
also adopts existing domestic rules for tank vessels that have glands 
or pressure seals on the gastight bulkhead between machinery spaces and 
hazardous locations. In new Sec.  111.106-15, this rule adopts portions 
of IEC 60092-502, Clause 8, as well as existing gas carrier rules at 46 
CFR 154.1205 with respect to air changes and related ventilation 
requirements. This rule also addresses the prevention of static build-
up in cargo tanks and piping by requiring electrical bonding in 
accordance with Sec.  153.461 for flammable or combustible cargoes.
    The regulations in Subpart 111.106 are similar to regulations the 
Coast Guard has proposed in a separate rulemaking project regarding 
electrical equipment in hazardous locations on board foreign Mobile 
Offshore Drilling Units (MODUs), floating OCS facilities, and vessels 
that engage in OCS activities, excluding OSVs (78 FR 37760). Although 
the regulations are very similar because the Coast Guard's overall 
policy and safety concerns are the same, neither rulemaking project is 
intended to conflict with or modify the other. The proposed rule on 
hazardous locations affects a different group of vessels and 
facilities, not large OSVs.

U. Amendments to 46 CFR Part 174, Subpart G, ``Special Rules Pertaining 
to Offshore Supply Vessels''

    As discussed above, this interim rule revises Sec.  127.230 to 
exempt large OSVs from Part 174, Subpart G, because large OSVs must 
instead meet SOLAS requirements for stability. Therefore this rule 
modifies Sec.  174.180, which is the applicability provision of Subpart 
G, to clarify that large OSVs need not meet Subpart G.

V. Amendments to Incorporation by Reference Sections, 46 CFR Parts 110 
and 125

    Many of the substantive changes discussed earlier in this preamble 
involve industry standards or other published material that this 
interim rule incorporates by reference. Incorporating these industry 
standards ensures that our regulations are based on the consensus of 
experts in the field, and increases the likelihood they are compatible 
with established best practices and international standards. When Coast 
Guard regulations require compliance with the provisions of these 
standards, the provisions should be read as mandatory regulatory 
requirements even if the standard development organization has used 
advisory or recommendatory language.
    The incorporated standards are listed in existing centralized 
incorporation by reference sections at 46 CFR 110.10-1 and 125.180. In 
addition to incorporating new material necessary to the substance of 
the rule, this rule reformats the existing incorporation by reference 
sections for consistency with Office of the Federal Register drafting 
guidelines, and provides updated publisher contact information. This 
interim rule does not remove, replace, or otherwise affect any material 
previously incorporated by reference. Because reformatting and the 
addition of publisher contact information are administrative changes 
with no substantive effect on the public, the Coast Guard finds good 
cause to make these changes effective immediately and without prior 
notice and comment, as described in Section IV of this preamble.

VII. Incorporation by Reference

    The Director of the Federal Register has approved the material in 
46 CFR 110.10-1 and 125.180 for incorporation by reference under 5 
U.S.C. 552 and 1 CFR part 51. You may inspect this material at U.S. 
Coast Guard Headquarters where indicated under ADDRESSES. Copies of the 
material are available from the sources listed in 46 CFR 110.10-1 and 
125.180.

VIII. Regulatory Analyses

    We developed this interim rule after considering numerous statutes 
and executive orders related to rulemaking. Below, we summarize our 
analyses based on these statutes and executive orders.

A. Regulatory Planning and Review

    Executive Orders 12866 (``Regulatory Planning and Review'') and 
13563 (``Improving Regulation and Regulatory Review'') direct agencies 
to assess the costs and benefits of available regulatory alternatives 
and, if regulation is necessary, to select regulatory approaches that 
maximize net benefits (including potential economic, environmental, 
public health and safety effects, distributive impacts, and equity). 
Executive Order 13563 emphasizes the importance of quantifying both 
costs and benefits, of reducing costs, of harmonizing rules, and of 
promoting flexibility. This interim rule has been designated a 
``significant regulatory action,'' although not an economically 
significant regulatory action, under section 3(f) of Executive Order 
12866. Accordingly, the interim rule has been reviewed by the Office of 
Management and Budget. A preliminary Regulatory Analysis (RA) is 
available in the docket where indicated under the ``Public 
Participation and Request for Comments'' section of this preamble.
Pre-2010 Authorization Act Baseline
    Prior to the Authorization Act, owners wishing to build and operate 
OSVs were subject to a pre-existing system of regulations and 
standards. For example,

[[Page 48907]]

OSVs had to comply with Subchapter L requirements, including:
     Design plan review and approval
     Initial inspection and certification process
     Design standards
     Operating requirements, including manning
     Limitation on the size of OSVs (not greater than 6,000 GT 
ITC).
    However, as the OSV industry has become more heterogeneous, it has 
started to develop more size-specific standards and rules, particularly 
those focused on larger vessels--as opposed to the homogenous set of 
requirements currently required of all OSVs by the Coast Guard. This 
interim rule will update current regulations to account for this 
heterogeneity among OSVs. These size-specific standards have been 
adopted by international organizations and classification societies.
    Although the U.S. Coast Guard has never required OSVs to comply 
with international standards as a flag state in the past, prospective 
vessel owners and operators who wished to perform international work 
are required by international law to comply with international 
standards such as SOLAS, MARPOL, and ICLL. Because of the nature of OSV 
work, with contracts lasting a few months to a few years, owners and 
operators of larger OSVs have designed and constructed their vessels 
with the ``intent of being able to operate in nearly all major oil and 
gas producing regions of the world'' (i.e., the U.S. Gulf of Mexico, 
the Persian/Arabian Gulf, West Africa, and Brazil) in order to ensure 
that the vessel is able to mobilize immediately to a new region 
following the completion of its current contract.\2\ Compliance with 
some international standards is also required for participation in 
Coast Guard's Alternate Compliance Program (ACP).\3\ Based on the Coast 
Guard's MISLE database, our research indicates that all existing U.S.-
flagged OSVs greater than 3,000 GT ITC have complied with these 
international standards, and we expect that this trend will continue 
with OSVs larger than 6,000 GT as well. All of the OSVs greater than 
6,000 GT that have been built under the interim process have also 
voluntarily sought these international certificates.

Report.'' http://phx.corporate-ir.net/phoenix.zhtml?c=81406&p=irol-reportsannual.
    \3\ The ACP is a voluntary program in which Classification 
Society Rules, International Conventions, and an approved U.S. 
Supplement provide an alternative that is equivalent to Title 46, 
Code of Federal Regulations (CFR).
---------------------------------------------------------------------------

    Similarly, for insurance and other market-driven reasons, owners of 
OSVs are complying voluntarily with Classification Society standards. 
Based on Coast Guard's MISLE database, all OSVs in the 3,000 to 6,000 
GT ITC range have voluntarily been classed by an approved 
Classification Society. All of the OSVs greater than 6,000 GT that have 
been built under the interim process have also voluntarily been 
classed.
    Recent practice shows that some owners of large OSVs elect to 
pursue multiple certifications under other subchapters to provide 
flexibility to match client needs and to maximize revenue generation 
potential. For example, OSVs have been certificated under, and 
therefore have to comply with the requirements in, subchapters I, D, 
and O to act as petroleum and chemical tankers in addition to acting as 
supply vessels.\4\ With this rulemaking, ship owners and operators will 
have specific standards in Subchapter L to address the design, 
construction, and operation of these larger vessels that can perform 
multiple services, thereby no longer needing to get certificated under 
multiple subchapters in order to perform multipurpose work. These 
standards primarily align with existing Coast Guard regulations, as 
well as with international requirements that ship owners and operators 
would likely comply with anyway to safely meet energy market demands 
and pursue offshore energy ventures that are farther offshore and in 
deep waters.

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

2010 Authorization Act Requirements
    In the Coast Guard Authorization Act of 2010, Congress removed the 
size limit on OSVs and directed the Coast Guard to implement 
regulations for OSVs of at least 6,000 gross tonnage as defined by the 
International Convention on Tonnage Measurement of Ships 1969 (6,000 GT 
ITC). Congress also directed the Coast Guard to issue regulations to 
implement the Act and ``to ensure the safe carriage of oil, hazardous 
substances, and individuals in addition to the crew on such vessels'' 
(see section 617(f) of the Act).
    In addition to removing the size limit, Congress also specified 
requirements in three areas for OSVs greater than 6,000 GT ITC:
     Oil fuel tank protection;
     The number and qualification of crew; and
     Division of watches.
    These additional requirements provide enhanced levels of 
environmental protection and safety, which is needed as a result of 
large OSVs carrying a larger quantity of oil and hazardous material, as 
well as a larger number of persons on board. Because these expanded 
services are more typically provided by tank and cargo vessels, the 
Coast Guard has based its enhanced requirements on existing provisions 
in Subchapters I, O, and D. Through doing so, we expect no additional 
cost impacts, because OSVs would already be required under the existing 
regulatory regime to comply with these additional Subchapters if they 
wished to provide the additional services governed by those 
Subchapters.
Interim Process
    Following the passage of the Act, a new interim process was 
established, which allows the construction of vessels of at least 6,000 
GT ITC to be certificated as large OSVs on a case-by-case basis. Under 
this case-by-case process, large OSVs would be approved under the 
existing regulatory structure, whereby the vessel would be required to 
meet existing Coast Guard regulations applicable to smaller U.S.-
flagged OSVs, and, in cases in which the vessel wished to provide dual 
services (such as also acting as a tanker or cargo vessel), the vessel 
would also be required to meet the applicable existing regulations for 
those vessel types. Under the interim process thus far, prospective 
vessel owners and operators voluntarily agreed during the design basis 
stage of the interim process to meet the interational standards 
required for international work (SOLAS, MARPOL, and ICLL) and class 
standards. As noted previously, 100 percent of existing OSVs in the 
3,000-6,000 GT range have voluntarily complied with these international 
requirements so as to be able to compete for work on the international 
market.
Need for Federal Regulatory Action
    The interim rule is needed for several reasons. Primarily, this 
interim rule allows the Coast Guard to fulfill Congress' direction to 
issue an interim rule ``as soon as is practicable'' to implement the 
2010 Authorization Act. The interim rule also codifies existing current 
industry practices of larger OSVs (from 3,000 GT ITC to 6,000 GT ITC) 
in areas such as compliance with international standards and 
classification. The interim rule helps to ensure the safe carriage of 
oil, hazardous substances, and individuals in addition to the crew on 
OSVs of at least 6,000 GT ITC by specifying requirements that reflect 
the operating characteristics of larger OSVs.
    Further, as a result of this rulemaking, ship owners and operators 
will have

[[Page 48908]]

specific standards in Subchapter L to address the design, construction, 
and operation of these larger vessels, thereby no longer needing to get 
certificated under multiple subchapters in order to perform 
multipurpose work. These standards primarily align with existing Coast 
Guard regulations, as well as with international requirements that ship 
owners and operators would likely comply with anyway to safely meet 
energy market demands and pursue offshore energy ventures that are 
farther offshore and in deep waters.
    In comparison with the interim process, the interim rule eliminates 
the regulatory uncertainty and inefficiencies that the current case-by-
case process inherently produced for both industry and government. 
Instead of going through a lengthy case-by-case review, this interim 
rule will provide specific standards in subchapter L for owners and 
operators to meet when designing and constructing a large OSV and will 
establish a standardized regulatory oversight process for government 
officials. In addition to improving efficiency, the interim rule will 
improve transparency, as the standards that Coast Guard applies will be 
publicly available and subject to public comment before finalization.
Affected Population
    Currently, the portion of the global OSV market served by OSVs of 
at least 6,000 GT ITC is largely captured by non-U.S. vessels as shown 
in Table 1 below, given past statutory restrictions on OSV size and 
uncertainties regarding the interim process.\5\ The table identifies 
domestic firms' share of the OSV market for the 1,001 through 6,000 
gross tonnage ranges, in which U.S.-flagged OSVs account for 
approximately 10 percent of the world fleet. This interim rule will 
open the markets served by OSVs of at least 6,000 GT ITC to domestic 
entities.
---------------------------------------------------------------------------

    \5\ There exist two U.S.-flagged vessels of at least 6,000 GT 
ITC currently operating in U.S. waters. These vessels have been 
certificated under the interim process created by section 617(f)(3) 
of the Act as large OSVs that meet subchapter I and additional 
requirements from design basis agreements.

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

    The offshore energy market has experienced increased demand for 
high endurance operations required for deepwater exploration far 
offshore. ``Since the first major deepwater leasing boom in 1995 and 
1996, a sustained and robust expansion of deepwater drilling activity 
has occurred, largely enabled by major advances in drilling technology. 
In 2001, U.S. deepwater offshore oil production surpassed shallow water 
offshore oil production for the first time. By 2009, 80 percent of 
offshore oil production and 45 percent of natural gas production 
occurred in water depths in excess of 1,000 feet, and industry had 
drilled nearly 4,000 wells to those depths.'' \8\ This trend toward 
exploration in deep water and farther offshore necessitates larger OSVs 
that can haul more offshore workers, excess fuel, drill string, and 
mud. Further, it requires OSVs that are better equipped to handle 
platform support and construction, subsea construction and pipelaying, 
diving support, as well as towing of rigs and well stimulation. OSVs 
under 6,000 GT ITC do not have the capacity to meet these additional 
capabilities farther offshore, and as a result, industry is turning to 
OSVs of at least 6,000 GT ITC to fill these needs. ``The demand for 
large [platform supply vessels, which are a type of OSV] with dynamic 
positioning has outpaced the supply of vessels for most of 2012. New 
deliveries and [OSVs] mobilizing back to the U.S. Gulf [of Mexico] have 
been unable to keep up with demand, forcing drilling operators to 
supplement smaller vessels, which are readily available. While these 
smaller vessels may be adequate, they are not optimal for deepwater 
support work.'' \9\

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

    The Coast Guard anticipates that domestic entities would like to 
capture some of this market, as evidenced by the construction of two, 
and the design basis application and approval for an additional four, 
U.S.-flagged vessels of at least 6,000 GT ITC. This interim rule would 
permit U.S.-flagged vessels of at least 6,000 GT ITC to be certificated 
as OSVs under subchapter L standards, which would allow U.S. firms to 
benefit from access to this increased demand.
    While the Coast Guard is unable to forecast with certainty the 
number of U.S.-flagged OSVs of at least 6,000 GT ITC that may be built 
to meet the increasing demand for larger OSVs, the number of vessels 
constructed or seeking approval under the interim process found in 
section 617(f)(3) of the Act may provide some insight. In 2013, four 
vessels sought approval under this process, while two vessels have 
already been constructed.
    Furthermore, the Coast Guard anticipates that this new population 
of OSVs will follow a growth pattern similar to that of OSVs greater 
than 3,000 GT ITC but less than 6,000 GT ITC since this was the extent 
of larger sized U.S.-flagged OSV growth under the size limit 
restriction.
    Through review of the Marine Information for Safety and Law 
Enforcement (MISLE) database, the Coast Guard has determined that on 
average four U.S.-flagged OSVs between 3,001 and 6,000 GT ITC were 
constructed per year from 1998 through 2013.
    Given the current environment of the offshore energy market, the 
Coast Guard anticipates that the number of large U.S.-flagged OSVs 
built per year will be similar to the number of U.S.-flagged OSVs 
between 3,001 and 6,000 GT ITC built per year from 1998 through 2013. 
Therefore, we do not expect more than four U.S.-flagged OSVs of at 
least 6,000

[[Page 48909]]

GT ITC would be built per year after publication of this interim rule. 
Further, we anticipate that the vessels of at least 6,000 GT ITC will 
be built instead of (rather than in addition to) vessels in the 3,001 
to 6,000 GT ITC size range.

                                     existing vessels. Although USCG
                                     does not have data to forecast the
                                     number of U.S.-flagged OSVs of at
                                     least 6,000 GT ITC that may be

                                     for larger OSVs with certainty, we
                                     anticipate that it is likely that
                                     the construction of OSVs of at
                                     least 6,000 GT ITC will follow a
                                     similar growth pattern, and may be
                                     built instead of, the construction
                                     of OSVs between 3,001 to 6,000 GT
                                     ITC. If this assumption holds, then

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

Baseline for Analysis of Impacts
    Before the Act, U.S. ship owners and operators wishing to build an 
OSV were subject to a network of regulations, voluntary standards and 
industry practices, including a prohibition against constructing U.S.-
flagged OSVs of at least 6,000 GT ITC, because of the Coast Guard's 
1996 regulation, which capped the tonnage of an OSV. The Authorization 
Act lifted the tonnage restriction, but left the remainder of the 
regulatory and standard network in place. The baseline for determining 
the impact of the interim rule is thus the pre-Authorization Act 
network of regulations, voluntary standards, and current industry 
practices.
Analysis of Cost Impacts
    This section details the analysis of cost impacts of the interim 
rule requiring large OSVs to meet design, construction, and operation 
safety regulations governing the inspection and standards of OSVs, 
found in Title 46. We expect industry will incur no additional costs in 
meeting the Coast Guard's rule as the incorporated standards or 
functionally equivalent standards will be used to construct a large OSV 
in the absence of any rule.
    In order to minimize the impact of this rule on industry, the Coast 
Guard based the majority of the provisions in this interim rule upon 
existing regulatory and technical standards from Titles 33 and 46 of 
the CFR. Although the Coast Guard deviated from these existing 
standards in several instances, these changes were made in order to 
account for differences between the scale of operations of the existing 
standard's intended population and the operations of large OSVs.\10\ 
Where existing regulatory and technical standards were not appropriate, 
the Coast Guard supplemented them with standards from IMO conventions 
and industry consensus engineering standards.
---------------------------------------------------------------------------

    \10\ Provisions in this interim rule in which the Coast Guard 
deviated from existing standards include electrical requirements in 
46 CFR subchapter J.
---------------------------------------------------------------------------

    Because of the previous size limit on OSVs, there were no U.S.-
flagged vessels of at least 6,000 GT ITC or 500 GRT operating as 
OSVs.\11\ However, since the Act was enacted, two U.S.-flagged vessels 
of at least 6,000 GT ITC have been certificated under the interim 
process found in section 617(f)(3) of the Act as large offshore supply 
vessels that meet subchapter I and additional requirements from design 
basis agreements, and four more have had their design basis agreements 
approved. Although these would be grandfathered from having to comply 
with this interim rule, the international standards codified in this 
rule were derived from standards that these owners and operators 
voluntarily agreed to adopt under the interim process.\12\ 
Consequently, this rule will not directly impact any existing 
population of U.S. vessels, nor is it expected to add additional costs 
to newly constructed OSVs of at least 6,000 GT ITC, as these vessels 
are also expected to work internationally in addition to working 
domestically. Therefore, no additional costs will be incurred by 
industry in the construction of a large OSV.
---------------------------------------------------------------------------

    \11\ While it is possible that an owner of an existing large OSV 
certificated under the interim process found in 617(f)(3) of the Act 
may seek recertification under subchapter L, no one from industry 
has inquired about this issue in the two and a half years since the 
Act was enacted.
    \12\ Although these six vessels are expected to work 
domestically, they are also expected to work internationally, and 
therefore, would be held to international standards as well.
---------------------------------------------------------------------------

    At this time, the Coast Guard does not anticipate additional costs 
to the government from inspections and plan review. Although this rule 
removes the size restriction of vessels certificated under subchapter L 
as OSVs, the population of new OSVs of at least 6,000 GT ITC is 
expected to replace a portion of the population of OSVs in the 3,001 GT 
ITC to 6,000 GT ITC size.
    Further, because the provisions in this rule that result in 
government costs are also required of vessels approved under the 
617(f)(3) interim process, the expected costs that would be incurred by 
government to conduct inspections and plan reviews as a result of this 
interim rule would have been incurred by the government even in the 
absence of this rule. Therefore, the Coast Guard expects to use 
existing resources to implement this rule.
    This section presents a qualitative analysis of the cost impacts 
and justifications for Title 46 revisions implemented by this interim 
rule. We present our analyses in grouped sections that correspond to 
each aspect of the rule, which impacts 46 CFR as shown below. Further 
details are provided in the regulatory analysis available in the 
docket.

    \13\ Impact is negligible because the carriage of oil-based mud 
is also covered by requirements for the carriage of noxious liquid 
substances (46 CFR 125.120). Because of the various chemical 
components within the muds, nearly all mud carried by larger OSVs is 
authorized only if the vessel complies with international pollution 
prevention standards (IMO Resolution A.673(16)), which already 
requires minimum distances for cargo from the outer hull.

Benefits of the Interim Rule
    In the Act, Congress removed the tonnage limit on vessels 
certificated under subchapter L as OSVs, and directed the Coast Guard 
to implement regulations for the safe carriage of oil, hazardous 
substances, and individuals in addition to the crew on OSVs of at least 
6,000 GT ITC. However, the provisions in the Act allow ship owners and 
operators to construct vessels that can operate as OSVs, by meeting 
subchapter I and additional requirements from design basis agreements, 
during the period between the effective date of the Act and the 
effective date of this rulemaking provided they obtain Coast Guard 
approval. This process creates regulatory inefficiencies as there are 
no large OSV subchapter L-specific standards and regulatory 
flexibilities for industry to reference, which could result in 
construction and design delays. First, industry must submit a proposed 
design to begin the process, and each time a change to the vessel's 
design is made, the process must start over as the company must 
resubmit a new design letter. After this step has been completed, 
industry must then wait for the design basis to be approved before 
beginning construction of the vessel. According to a Coast Guard 
subject matter expert, this design basis process can take, at a 
minimum, 30 days to complete, with additional time taken for the 
company to respond to the draft design basis agreements. However, it is 
likely that, based on the complexity of the design of OSVs of at least 
6,000 GT ITC, this process would take the Coast Guard much longer to 
complete.
    Accordingly, the Coast Guard developed this interim rule to rectify 
this lack of transparent standards to ensure consistent design, 
construction, and operation of OSVs, as well as to comply with the Act.
    On top of rectifying this lack of transparent standards, it is 
expected that this rule will reduce costs overall. Because vessels 
approved under the 617(f)(3) interim process are approved under a case-
by-case basis, a substantial amount of resources are used throughout 
the approval process.

[[Page 48917]]

Issuance of this interim rule would streamline the construction process 
by removing this case-by-case process and replacing it with transparent 
requirements that all newly constructed vessels wishing to be 
certificated as large OSVs must adhere to. This is expected to 
significantly reduce costs.
    Therefore, this rule will replace government's existing ad hoc 
processes and requirements with a more streamlined and predictable 
system, thereby reducing resources and, consequently, costs.

                                                    requirements.
------------------------------------------------------------------------

Alternatives
    When creating this interim rule, the Coast Guard considered several 
alternatives. As discussed elsewhere, the preferred alternative closely 
follows the actual and mandatory language of the Act and does not 
incorporate substantive discretionary elements. Further, the preferred 
alternative minimizes cost while maximizing cost savings that would 
accrue to industry and government as a result of implementation of an 
interim rule.
    The alternatives considered are as follows.
Alternative 1: Preferred Alternative
    The analysis for this alternative is discussed in detail previously 
in this rule.
Alternative 2: No Action Alternative
    In this alternative, the Coast Guard would not issue an interim 
rule, but instead continue to use the interim process outlined in 
617(f)(3) of the Act.
    Instead of incorporating by reference industry and international 
standards, this alternative would continue to rely on a case-by-case 
process to approve the construction of new vessels over 6,000

[[Page 48920]]

GT ITC. This would continue to result in regulatory inefficiencies in 
the approval process and long delays in the construction and design of 
new vessels. Finally, by making the requirements of large OSVs explicit 
and transparent, regulatory uncertainty and confusion are potentially 
reduced.
    Therefore, because the benefits of this alternative were less than 
that of the preferred alternative, the Coast Guard rejected this 
alternative.
Alternative 3: Issuance of Proposed Alternative as an NPRM
    In this alternative, the Coast Guard would require all of the 
provisions in the preferred alternative, but would propose the 
alternative as an NPRM instead of as an interim rule.
    Because the provisions in the preferred alternative are derived 
either directly from existing regulatory and technical standards from 
Titles 33 and 46 of the CFR or developed and rooted from current 
domestic and international standards that industry already voluntarily 
complies with, the Coast Guard rejected this provision, as it would 
only delay potential cost savings that could accrue from immediate 
implementation.
Alternative 4: Adoption of International Standards Only
    In this alternative, the Coast Guard would require that vessels 
meet international standards only. Coast Guard considered and adopted 
international standards for many requirements. However, for a limited 
number of areas, Coast Guard found that international standards needed 
to be supplemented to provide consistency with already in place 
domestic standards and to ensure safe operations and design.
    The Coast Guard rejected the alternative of adopting only 
international standards as, in some limited cases, the international 
standards are not consistent with existing domestic standards or need 
further clarification where details are left to the satisfaction of the 
administration. In addition, for several requirements, Coast Guard 
offers industry the flexibility of a choice of standards. This 
flexibility would be lost if Coast Guard adopted only international 
standards.

B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have 
considered whether this interim rule would have a significant economic 
impact on a substantial number of small entities. The term ``small 
entities'' comprises small businesses, not-for-profit organizations 
that are independently owned and operated and are not dominant in their 
fields, and governmental jurisdictions with populations of less than 
50,000.
    Because of the previous size limit on OSVs, there were no U.S.-
flagged vessels of at least 6,000 GT ITC or 500 GRT operating as 
OSVs.\14\ However, since the Act was enacted, two U.S.-flagged vessels 
of at least 6,000 GT ITC have been certificated as large OSVs under the 
interim process found in section 617(f)(3) of the Act that meet 
subchapter I and additional requirements from design basis agreements, 
with four others pursuing the interim certification. Although these 
would be grandfathered from having to comply with this interim rule, 
the international standards codified in this rule were derived from 
standards that these owners and operators voluntarily agreed to adopt 
as a condition of approval under the interim process.\15\ Consequently, 
this rule will not directly impact any existing population of U.S. 
vessels, nor is it expected to add additional costs to newly 
constructed OSVs of at least 6,000 GT ITC, as these vessels are also 
expected to work internationally in addition to working domestically. 
Therefore, no additional costs will be incurred by industry in the 
construction of a large OSV.
---------------------------------------------------------------------------

    \14\ While it is possible that an owner of an existing large OSV 
certificated under the interim process as meeting subchapter I and 
additional requirements as specified under the design basis 
agreements may seek recertification under subchapter L, no one from 
industry has inquired about this issue in the 2 and a half years 
since the Act was enacted.
    \15\ Although these six vessels are expected to work 
domestically, they are also expected to work internationally, and 
therefore, would be held to international standards as well.
---------------------------------------------------------------------------

    In our review of the MISLE ownership data for OSVs, we found 67 
U.S.-flagged OSVs between 3,001 and 6,000 GT ITC that are owned and 
operated by 23 entities. The Coast Guard has identified 10 parent 
companies that direct the 23 managing entities, which we then grouped 
by their North American Industry Classification System (NAICS) code. 
Parent companies that direct managing entities may be classified under 
a range of NAICS codes due to the vertical integration and 
consolidation of business interests and operations. Based on the data 
from the Coast Guard's MISLE database used to populate the domestic 
vessel field in Table 2-1, the Coast Guard determined that none of 
businesses affected are small by the Small Business Administration 
(SBA) size standards. Therefore, the Coast Guard certifies under 5 
U.S.C. 605(b) that this interim rule will not have a significant 
economic impact on a substantial number of small entities.

    For additional analysis on the estimated impact that this interim 
rule would have on small entities, please see the preliminary RA 
available in the docket where indicated under the ``Public 
Participation and Request for Comments'' section of this preamble.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this rule will have a 
significant economic impact on it, please submit a comment to the 
Docket Management Facility at the address under ADDRESSES. In your 
comment, explain why you think it qualifies and how and to what degree 
this rule would economically affect it.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small 
entities in understanding this interim rule so that they can better 
evaluate its effects on them and participate in the rulemaking. If the 
interim rule would affect your small business, organization, or 
governmental jurisdiction and you have questions concerning its 
provisions or options for compliance, please consult Lieutenant Anne 
Besser, Project Manager, CG-ENG-1, Coast Guard, email 
[email protected], telephone 202-372-1362. The Coast Guard will not 
retaliate against small entities that question or complain about this 
rule or any policy or action of the Coast Guard.
    Small businesses may send comments on the actions of Federal 
employees who enforce, or otherwise determine compliance with, Federal 
regulations to the Small Business and Agriculture Regulatory 
Enforcement Ombudsman and the Regional Small Business Regulatory 
Fairness Boards. The Ombudsman evaluates these actions annually and 
rates each agency's responsiveness to small business. If you wish to 
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR 
(1-888-734-3247).

D. Collection of Information

    This interim rule does not call for a collection of information 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).
    The offshore energy market has experienced increased demand for 
high endurance operations required for deepwater exploration far 
offshore. Accordingly, this trend necessitates industry to design, 
construct, and operate OSVs with greater endurance, stability, and 
carriage characteristics.
    ``The demand for large [platform supply vessels, which are a type 
of OSV] with dynamic positioning has outpaced the supply of vessels for 
most of 2012. New deliveries and [OSVs] mobilizing back to the U.S. 
Gulf [of Mexico] have been unable to keep up with demand, forcing 
drilling operators to supplement smaller vessels, which are readily 
available. While these smaller vessels may be adequate, they are not 
optimal for deepwater support work.'' \16\ The Coast Guard anticipates 
that domestic entities would like to capture some of this market, which 
is currently restricted to only foreign-flagged OSVs because of the 
size limit restriction on U.S.-flagged OSVs. This interim rule would 
permit U.S.-flagged vessels of at least 6,000 GT ITC to be certificated 
as OSVs under subchapter L, which would allow U.S. firms to meet some 
of this increased demand.

Supply Vessels in the Gulf of Mexico.'' http://www.marcon.com/index.cfm?SectionListsID=49&PageID=2461.
---------------------------------------------------------------------------

    While the Coast Guard is unable to forecast with a sufficient 
degree of certainty the number of U.S.-flagged OSVs of at least 6,000 
GT ITC that may be built to meet the increasing demand for larger OSVs, 
the number of vessels seeking approval under the interim process found 
in section 617(f)(3) of the Act may provide some insight. In 2013, four 
vessels sought approval under this process.
    Furthermore, the Coast Guard anticipates that this new population 
of OSVs will follow a growth pattern similar to that of OSVs greater 
than 3,000 GT ITC but less than 6,000 GT ITC.
    Through review of the MISLE database, the Coast Guard has 
determined that on average four U.S.-flagged OSVs between 3,001 and 
6,000 GT ITC were constructed per year from 1998 through 2013. While 
the continuation of this trend cannot be assured, given the current 
environment of the offshore energy market, it is unlikely that the 
construction of OSVs of at least 6,000 GT ITC will exceed nine in any 
given year, particularly during the next 3 years (the period covered by 
a Collection of Information).
    Therefore, because the information collected under this rule is 
expected to involve fewer than 10 vessels in a given year, it is not a 
collection of information that requires a formal burden estimate as 
defined in section 3502 of the Paperwork Reduction Act.
    The Coast Guard welcomes any comments or concerns on the collection 
of information discussed in this section. Your comments must be sent to 
the Office of Information and Regulatory Affairs (OIRA), Office of 
Management and Budget. To ensure that your comments to OIRA are 
received on time, the preferred methods are by email to [email protected] (include the docket number and ``Attention: Desk 
Officer for Coast Guard, DHS'' in the subject line of the email) or fax 
at 202-395-6566. An alternate, though slower, method is by U.S. mail to 
the Office of Information and Regulatory Affairs, Office of Management 
and Budget, 725 17th Street NW., Washington, DC 20503, ATTN: Desk 
Officer, U.S. Coast Guard.

E. Federalism

    A rule has implications for federalism under Executive Order 13132, 
Federalism, if it has a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. We have analyzed this rule under that Order and have 
determined that it does not have federalism implications.
    It is well settled that States may not regulate in categories 
reserved for regulation by the Coast Guard. It is also well settled, 
now, that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, 
and 8101 (design, construction, alteration, repair, maintenance, 
operation, equipping, personnel qualification, and manning of vessels), 
as well as the reporting of casualties and any other category in which 
Congress intended the Coast Guard to be the sole source of a vessel's 
obligations, are within the field foreclosed from regulation by the 
States. (See the decision of the Supreme Court in the consolidated 
cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 
120 S.Ct. 1135 (March 6, 2000).) This rule addresses the design, 
construction, alteration, repair, maintenance, operation, equipping, 
personnel qualification, and manning of OSVs of at least 6,000 GT ITC, 
or 500 GRT if GT ITC is not assigned. Because the States may not 
regulate within these categories, preemption under Executive Order 
13132 is not an issue.

F. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) 
requires Federal agencies to assess the effects of their discretionary 
regulatory actions. In particular, the Act addresses actions that may 
result in the expenditure by a State, local, or tribal government, in 
the aggregate, or by the private sector of $100,000,000 (adjusted for 
inflation) or more in any one year. Though this rule will not result in 
such an expenditure,

[[Page 48922]]

we do discuss the effects of this rule elsewhere in this preamble.

G. Taking of Private Property

    This rule will not cause a taking of private property or otherwise 
have taking implications under Executive Order 12630, Governmental 
Actions and Interference with Constitutionally Protected Property 
Rights.

H. Civil Justice Reform

    This rule meets applicable standards in sections 3(a) and 3(b)(2) 
of Executive Order 12988, Civil Justice Reform, to minimize litigation, 
eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this rule under Executive Order 13045, Protection 
of Children from Environmental Health Risks and Safety Risks. This rule 
is not an economically significant rule and does not create an 
environmental risk to health or risk to safety that may 
disproportionately affect children.

J. Indian Tribal Governments

    This rule does not have tribal implications under Executive Order 
13175, Consultation and Coordination with Indian Tribal Governments, 
because it does not have a substantial direct effect on one or more 
Indian tribes, on the relationship between the Federal Government and 
Indian tribes, or on the distribution of power and responsibilities 
between the Federal Government and Indian tribes.

K. Energy Effects

    We have analyzed this rule under Executive Order 13211, Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use, and have determined that it is not a 
``significant energy action'' under that order. Though it is a 
``significant regulatory action'' under Executive Order 12866, this 
interim rule is not likely to have a significant adverse effect on the 
supply, distribution, or use of energy. The Administrator of the Office 
of Information and Regulatory Affairs has not designated it as a 
significant energy action. Therefore, it does not require a Statement 
of Energy Effects under Executive Order 13211.

L. Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (15 
U.S.C. 272 note) directs agencies to use voluntary consensus standards 
in their regulatory activities unless the agency provides Congress, 
through the Office of Management and Budget, with an explanation of why 
using these standards would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., specifications of materials, performance, design, or 
operation; test methods; sampling procedures; and related management 
systems practices) that are developed or adopted by voluntary consensus 
standards bodies.
    This rule uses the following voluntary consensus standards:

M. Environment

    We have analyzed this interim rule under Department of Homeland 
Security Management Directive 023-01 and Commandant Instruction 
M16475.lD, which guide the Coast Guard in complying with the National 
Environmental Policy Act of 1969 (NEPA)(42 U.S.C. 4321-4370f), and have 
concluded that this action is one of a category of actions that do not 
individually or cumulatively have a significant effect on the human 
environment. This rule is categorically excluded under section 2.B.2, 
figure 2-1, paragraphs (34)(a), (c), (d) and (e) of the Instruction and 
under section 6(a) and (b) of the ``Appendix to National Environmental 
Policy Act: Coast Guard Procedures for Categorical Exclusions, Notice 
of Final Agency Policy'' (67 FR 48243, July 23, 2002). This rule 
involves regulations concerning the manning, documentation, 
measurement, inspection, and equipping of vessels; regulations 
concerning equipment approval and carriage requirements; regulations 
concerning vessel operation safety standards; and congressionally 
mandated regulations designed to protect the environment. An 
environmental analysis checklist and a categorical exclusion 
determination are available in the docket where indicated under 
ADDRESSES.

55. Add Sec.  132.365 to read as follows:


Sec.  132.365  Emergency outfits.

    (a) Two emergency outfits, stored for use in widely separated, 
accessible locations, are required on all OSVs of at least 6,000 GT ITC 
(500 GRT if GT ITC is not assigned) that have cargo tanks that exceed 
15 feet in depth, measured from the tank top to the lowest point at 
which cargo is carried.
    (b) Each emergency outfit must have on board the following 
equipment:
    (1) One pressure-demand, open-circuit, self-contained breathing 
apparatus, approved by the Mine Safety and Health Administration and by 
the National Institute for Occupational Safety and Health and having at 
a minimum a 30-minute air supply, a full facepiece, and a spare charge.
    (2) One lifeline with a belt or a suitable harness.
    (3) One Type II or Type III flashlight constructed and marked in 
accordance with ASTM F1014--02 (incorporated by reference, see Sec.  
125.180).
    (4) One fire axe.
    (5) One pair of boots and gloves of rubber or other electrically 
nonconducting material.
    (6) One rigid helmet that provides effective protection against 
impact.
    (7) One set of protective clothing of material that will protect 
the skin from the heat of fire and burns from scalding steam. The outer 
surface must be water resistant.
    (c) Lifelines must be of steel or bronze wire rope. Steel wire rope 
must be either inherently corrosion resistant or made so by galvanizing 
or tinning. Each end must be fitted with a hook with keeper having a 
throat opening that can be readily slipped over a \5/8\-inch bolt. The 
total length of the lifeline must be dependent upon the size and 
arrangement of the vessel, and more than one line may be hooked 
together to achieve the necessary length. No individual lifeline may be 
less than 50 feet in length. The assembled lifeline must have a minimum 
breaking strength of 1,500 pounds.

56. Add Sec.  132.390 to read as follows:


Sec.  132.390  Added requirements for carriage of flammable or 
combustible cargo.

    (a) This section applies to OSVs of at least 6,000 GT ITC (500 GRT 
if GT ITC is not assigned).
    (b) Cargo tanks containing flammable or combustible liquids must 
not be located beneath the accommodations or machinery space. 
Separation by cofferdams is not acceptable for meeting this 
requirement.
    (c) Except for OSVs complying with paragraph (d)(1) of this 
section, each OSV must carry at least two approved semiportable dry 
chemical fire extinguishers for the protection of all weather deck 
areas within 10 feet (3 m) of any tank openings, pumps, flanges, 
valves, vents, or loading manifolds. Each extinguisher must have--
    (1) A minimum capacity of 135 kg. If the protected area exceeds 90 
m\2\, additional extinguishers must be provided to supply a total 
combined capacity of dry chemical in kilograms equal to the total 
combined protected area in square meters multiplied by 3;
    (2) A minimum flow rate of 3 kg/min from each discharge hose;
    (3) A sufficient number of discharge hoses of adequate length to 
protect the areas required above without moving any of the 
extinguishers; and
    (4) The frame or support for each semi-portable dry chemical fire 
extinguisher welded or otherwise permanently attached to the vessel's 
structure.
    (d) Each OSV with fixed cargo tanks that have an aggregate capacity 
of 3,000 cubic meters or more intended for the carriage of flammable or 
combustible liquids with a closed-cup flashpoint of 60[deg] C or below 
must have:
    (1) An approved fixed-deck foam system arranged as follows:
    (i) If the flammable or combustible liquid tanks extend vertically 
to the weather deck, the foam system must comply with Sec. Sec.  34.20-
10 and 34.20-15 of this chapter, and protect the entire weather deck 
cargo area, including any tank openings, pumps, flanges, valves, vents, 
or loading manifolds. If petroleum products are carried, the minimum 
foam system discharge rate in liters per minute must be determined by 
multiplying the total cargo deck area by 6 lpm/m\2\. If polar solvent 
cargoes are carried, the minimum foam system discharge rate in liters 
per minute must be determined by multiplying the total cargo deck area 
by 10 lpm/m\2\, unless the approved foam system design manual specifies 
a different rate for the cargoes carried.
    (ii) If the flammable or combustible liquid tanks do not extend 
vertically to the weather deck, the foam system must be capable of 
protecting all weather deck areas within 10 feet (3 m) of any tank 
openings, pumps, flanges, valves, vents, or loading manifolds. The foam 
system must consist of at least one hoseline, and either fixed-foam 
monitors or fixed-foam nozzles that provide foam coverage of all 
required areas. The minimum foam system discharge rate must be 
calculated in accordance with paragraph (d)(1)(i) of this section, 
using the combined horizontal area of all parts of the deck requiring 
protection, instead of the total deck area.
    (iii) All foam liquid concentrate must be compatible with all 
flammable or combustible liquids carried.
    (iv) Sufficient foam liquid concentrate must be carried to allow 
operation of the system at its maximum discharge rate for at least 20 
minutes.
    (2) A fixed-gas fire-suppression system complying with Sec.  34.05-
5(a)(4) of this chapter, or other approved fire-extinguishing system 
determined acceptable by the Commandant, for the protection of any 
accessible below-deck cargo pump rooms or other spaces that have tank 
openings, pumps, flanges, valves, or loading manifolds associated with 
tanks carrying flammable or combustible liquids with a closed cup 
flashpoint of 60[deg] C or below.
