II. Executive Summary
Subchapter J of title 46 of the Code of Federal Regulations (CFR)
contains the electrical engineering regulations and standards
applicable to vessels and required shipboard systems regulated under
subchapters D, H, I, I-A, K, L, O, Q, R, T, U, and W of title 46. A key
component of subchapter J is the standards that are incorporated by
reference (IBR) in 46 CFR 110.10-1 and cross-referenced throughout
parts 110, 111, 112, and 113. On April 22, 2021, the Coast Guard
published a notice of proposed rulemaking (NPRM) that contains a
detailed description of the background and proposed changes. (86 FR
21440).
This final rule updates prior incorporations by reference in 46 CFR
110.10-1 and all of the sections in subchapter J that reference the
updated IBR standards, adds a limited number of alternative standards,
and eliminates outdated or unnecessarily prescriptive regulations in
subchapter J. More specifically, this rule incorporates more recent
editions of many standards, incorporates by reference additional
standards for certain topics, and removes IBR standards that are no
longer actively used by industry. Due to technological advances, it is
necessary to update the current standards to ensure modern technologies
are addressed in the regulations. In addition to updating the IBR
standards, this rule implements the following four changes to
subchapter J.
First, this rule eliminates the prescriptive requirements in 46 CFR
111.12-1(b) and (c) for generator prime movers. In accordance with 46
CFR 58.01-5, these generator prime movers continue to be required to
meet standards of the American Bureau of Shipping (ABS) Steel Vessel
Rules.
Second, this rule simplifies the electrical cable construction
requirements in subpart 111.60 so they are similar to the
classification society requirements currently accepted without
supplement under the Coast
[[Page 16311]]
Guard's Alternate Compliance Program (ACP).
Third, for classifications of hazardous locations in subpart
111.105, this rule adds the International Electrotechnical Commission's
(IEC) 60092-502 as an alternative classification. This is an
internationally accepted standard, and we are not aware of any notable
casualty history attributed to its use as compared to vessels complying
with the current applicable U.S. regulations for classification of
hazardous locations.
Fourth, this rule amends 46 CFR subpart 112.05 to allow the use of
an emergency generator in port. This optional capability to use
emergency generators in port is acceptable if a set of additional
safeguards, approved by the International Maritime Organization (IMO)
in 2005, are provided to ensure the availability of emergency power.
The following table provides an overview of the types of changes
and the affected sections.

III. Basis, Purpose, and Regulatory History
The legal basis of this rule is section 1333(d) of Title 43, United
States Code (U.S.C.), sections 3306 and 3703 of Title 46 U.S.C., and
Department of Homeland Security (DHS) Delegation No. 00170.1, Revision
No. 01.2. The provisions of 43 U.S.C. 1333(d) grant the Secretary of
the Department in which the Coast Guard is operating the authority to
promulgate and enforce regulations with respect to lights and other
warning devices, safety equipment, and other matters relating to the
promotion of safety of life and property on artificial islands,
installations, and other devices. The provisions of 46 U.S.C.
3306(a)(1) authorize the Secretary to prescribe regulations for the
design, construction, alteration, repair, and operation of vessels
subject to inspection, including equipment, appliances, propulsion
machinery, auxiliary machinery, boilers, unfired pressure vessels,
piping, and electric installations. Additionally, 46 U.S.C. 3703 grants
the Secretary authority to provide for navigation and vessel safety and
protect against hazards to life, property, and the marine environment
by regulating vessel construction, alteration, repair, maintenance,
operation, and equipping. DHS Delegation No. 00170.1, Revision No.
01.2, paragraph (II)(92)(b), delegates these authorities to the Coast
Guard.
The purpose of this rule is to update the standards incorporated by
reference in 46 CFR subchapter J, which provide detailed specifications
for electrical equipment used by vessels. Newly published editions of
the international standards referenced in subchapter J address new
technologies and changes in best practices. The Office of Management
and Budget's (OMB) Circular A-119 states agencies should undertake a
review of the standards
[[Page 16312]]
incorporated by reference every 3 to 5 years to remain current with
technological changes. OMB encourages reducing reliance on unique
government standards when an existing voluntary consensus standard
would suffice. This rule follows the Circular by incorporating newer
editions of industry standards and reducing the reliance on unique
Coast Guard standards where industry standards are sufficient.
On April 22, 2021, the Coast Guard published a NPRM titled ``Update
to Electrical Engineering Regulations'' (86 FR 21440) requesting
comments on the proposed changes implemented by this final rule,
including several updates to the standards incorporated by reference. A
detailed description of the background and proposed changes are
available in that NPRM. See 86 FR at 21442-60.
IV. Discussion of Comments and Changes
During the comment period for the April 22, 2021 NPRM (86 FR
21440), which ended on July 21, 2021, we received 15 comments. Several
commenters expressed their support for the Coast Guard updating the
standards incorporated by reference to newer editions and some
confirmed they use them in current practice. The comments also offered
us feedback on specific changes to the electrical engineering
requirements and standards we proposed to incorporate by reference. The
comments can be viewed in the docket following the instructions in the
ADDRESSES section of this preamble. We summarize the comments and our
responses, starting with general comments and then responding in order
of relevant CFR section. Within each CFR section, we describe any
changes to the final rule regulatory text from what was proposed in the
NPRM.
General
A commenter submitted an editorial comment on the list of
abbreviations in Section II for ``MOU.'' In this final rule, MOU is now
correctly defined as Mobile Offshore Unit.
A commenter requested we update 33 CFR subchapter N to clarify the
application of this rulemaking to Outer Continental Shelf (OCS)
facilities and stated that, at a minimum, the Coast Guard should update
33 CFR 143.120 to establish the date on which the proposed rule would
apply to a new floating OCS facility. Where subchapter N requires
compliance with subchapter J, the date of applicability for vessels and
facilities will begin 30 days after publication of this final rule, in
accordance with the revised Sec. 110.01-1(b). The updated requirements
and standards in subchapter J apply to electrical installations
contracted for after the effective date of the final rule.
The commenter also noted that the Bureau of Safety and
Environmental Enforcement (BSEE) in the Department of the Interior is
working on a regulatory update to incorporate more modern industry
standards and recommended the Coast Guard engage with BSEE to ensure
that both regulatory efforts are aligned, as the agencies propose to
incorporate different revisions of the same industry standard in at
least two cases. The Coast Guard and BSEE have a shared mission of
ensuring safety on the OCS. We work closely together to ensure our
requirements are not in conflict with each other, even if we use
different revisions of the same standard. Because this final rule is
not adding any new requirements for vessel owners and operators, it
will not cause any conflicts with BSEE requirements. Any specific
concerns can be addressed to either the Coast Guard's Eighth District
Outer Continental Shelf Division staff (website: https://www.atlanticarea.uscg.mil/D8/OCS/) or the Coast Guard's Outer
Continental Shelf National Center of Expertise (OCSNCOE) (website:
https://www.dco.uscg.mil/OCSNCOE/).
Two commenters requested that we clarify the applicability of
subchapter J to Floating Production Units (FPUs), as the Coast Guard
Office of Design and Engineering Standards' (CG-ENG) relevant policy
letter, CG-ENG Policy Letter 01-13,\1\ only applies to classed FPUs
rather than all FPUs in service. Similarly, a commenter requested that
the Coast Guard clarify the applicability of subchapter J to floating
OCS facilities, as the application of the subchapter has led to many
requests for equivalencies and alternatives for a class of
installations that may not technically be vessels. The comment stated
that the Coast Guard should act on the National Offshore Safety
Advisory Committee's recommendation that the Coast Guard issue a task
statement to evaluate the suitability of subchapters F and J for
floating OCS facilities. These requests are outside the scope of this
rulemaking, which focuses on updating the electrical engineering
standards set out in subchapter J but not further amending the
applicability of subchapter J. Nevertheless, we have shared them with
the appropriate Coast Guard offices. We encourage questions regarding
the applicable regulations for floating OCS facilities to be sent to
either the Coast Guard's Eighth District Outer Continental Shelf
Division Staff (website: https://www.atlanticarea.uscg.mil/D8/OCS/) or
OCSNCOE (website: https://www.dco.uscg.mil/OCSNCOE/).

---------------------------------------------------------------------------
Subpart 110.01--Applicability
Sec. 110.01-1 General
We received requests for information on the implementation dates
for the revised regulations. In response and to provide greater clarity
for the public, this final rule includes an amendment to Sec. 110.01-
1(b) that explains the effective date of the requirements in this rule.
The requirements implemented in this final rule will be effective 30
days after the publication of this final rule. Paragraph (b) will also
clarify that subchapter J applies only to electrical installations
contracted for after the effective date of this final rule. Existing
paragraph (c) of this section will continue to allow a vessel's
electrical installations to meet the subchapter J regulations in place
when those systems were initially installed. According to existing 46
CFR 110.01-3(a), repairs and replacements in kind must comply with
either the regulations in this subchapter or those in effect when the
vessel was built. Per Sec. 110.01-3(b), alterations and modifications,
such as re-engining, re-powering, upgrading of the main propulsion
control system, or replacing extensive amounts of cabling, must comply
with the regulations in this subchapter, including updates implemented
by this final rule. Per existing Sec. 110.01-1(c), all electrical
systems installed or under Coast Guard review prior to this date may
meet the regulations in place at the time of installation or submittal
to the Coast Guard.
Subpart 110.10--Reference Specifications, Standards, and Codes
Sec. 110.10-1 Incorporation by Reference
We received the following comments in regard to our update of the
technical standards incorporated by reference in subchapter J in Sec.
110.10-1.
Several commenters suggested incorporating by reference newer
editions than we had proposed to incorporate in Sec. 110.10-1. Because
of the frequent release of new editions, and the time necessary to
evaluate them and propose their incorporation, it is often impractical
to incorporate standards or new editions that publish after we issue
our NPRM. Instead, the Coast Guard considered whether the standards
proposed in the NPRM are still
[[Page 16313]]
sufficient and relevant to electrical engineering practices at the time
of this final rule, even if a newer edition is available. We determined
that the editions proposed in the NPRM are still sufficient and
relevant.
Several commenters requested incorporating by reference different
standards than are referenced in Sec. 110.10-1 or proposed in the
NPRM. The suggestions included standards and codes for alternative
propulsion fuels; inspection, maintenance, and repair of equipment in
hazardous locations; and hazardous location equipment directories or
dossiers. These topics are not currently addressed in subchapter J.
Including them at this stage would impose new regulatory requirements
on vessels and facilities. This rule is intended to update the existing
regulations in subchapter J and result in quantitative and qualitative
savings for vessel owners. For this reason, standards for topics not
currently addressed in subchapter J are outside the scope of this final
rule. We may consider some of these standards in the future for
incorporation by reference following a thorough technical analysis of
the standards as well as their potential costs and benefits. Further,
proposals for new requirements on topics not already included in
subchapter J would be given additional public notice and opportunity
for comment.
Additionally, we received specific comments on the following
standards we proposed for incorporation by reference.
American National Standards Institute (ANSI)/UL standards: A
commenter requested that we refer to the UL standards as ANSI/UL
standards. In many of the regulatory text sections we do refer to such
standards as ANSI/UL standards, but we do not do so in the IBR section,
Sec. 110.10-1. In that IBR section, we are required to list the
standard name exactly as it appears on the cover of the standard.
The commenter also noted that many ANSI/UL standards related to
hazardous locations replaced similar ISA standards, and suggested the
UL standards should be referenced throughout the CFR. We agree with
listing the ANSI/UL standards in addition to where we proposed to
include the ANSI/ISA standard because of their similarities in
requirements and options. In the NPRM we proposed to incorporate ANSI/
ISA 12.12.01 (2015). In this final rule we are also adding ANSI/ISA-
RP12.06.01 (2003) because it superseded a previously incorporated
standard we removed, ISA RP 12.6 (1995). These two are the only ANSI/
ISA standards that will be incorporated by reference in subchapter J
and both are active standards. Where the ANSI/ISA series of standards
are referenced in Sec. Sec. 111.105-3(b)(2), 111.106-3(b)(2), and
111.108-3(b)(2), this final rule adds the ANSI/UL series as an option
in those sections as well.
IEEE 100 (2000): A commenter noted that the Institute of Electrical
and Electronics Engineers (IEEE) withdrew the standard IEEE 100 (2000).
IEEE 100 (2000) is only referenced in Sec. 110.15-1 regarding
electrical and electronic term definitions. We have decided to retain
it in subchapter J because the definitions are still relevant. We have
confirmed that the standard is still available for the public to
purchase despite IEEE withdrawing it. We acknowledge that a revision to
the standard is underway and we will consider updating references to
this standard in the future.
IEEE 1580 (2010): A commenter suggested we incorporate the 2018
edition. The 2018 edition was still in the draft stage when we
published the NPRM in April 2021, and we were not able to propose draft
standards for incorporation by reference. The IEEE board approved the
IEEE 1580 (2021) on November 9, 2021, and published it on March 23,
2022, both dates after the comment period for the NPRM closed. The IEEE
1580 (2021) standard superseded the 2010 version. IEEE 1580 provides
recommended practice for marine cable use on shipboard and fixed or
floating facilities, and the 2021 edition addresses changes in changes
in technology and revisions to referenced standards since 2010. The
Coast Guard has decided that the 2010 version is still sufficient and
relevant for marine cables at the time of this final rule. However, the
public can submit equivalency requests for the 2021 edition to the
Marine Safety Center (MSC) in accordance with Sec. 110.20-1.
IEC 60092-302:1997: A commenter noted that this standard was
superseded by IEC 60092-303-2, Electrical installations in ships--Part
302-2: Low voltage switchgear and controlgear assemblies--Marine power,
published in 2019. We have decided to retain the 1997 edition until we
can thoroughly review the 2019 edition. However, we may consider
switchgear meeting the standards in IEC 60092-302-2:2019 under the
equivalency provisions of Sec. 110.20-1.
ISA RP 12.6:1995: We proposed in the NPRM to remove ISA RP 12.6
because ISA has withdrawn it. A commenter noted that a new standard,
ANSI/ISA RP12.06.01, has superseded ISA RP 12.6. The commenter is
correct. Because the two standards are very similar, we are replacing
the withdrawn ISA RP 12.6 standard with the new ANSI/ISA RP12.06.01
standard as suggested. This final rule incorporates by reference ANSI/
ISA-RP12.06.01:2003 in Sec. 111.105-11. ANSI/ISA-RP12.06.01 is a
recommended practice that promotes the uniform installation of
intrinsically safe systems in hazardous (classified) locations and
clarifies the requirements of Articles 504 and 505 of National Fire
Protection Association (NFPA) standard NFPA 70.
Subpart 110.25--Plan Submittal
Sec. 110.25-1 Plans and Information Required for New Construction
A commenter noted that the proposed changes to Sec. 111.105-3
provided the option to select electrical equipment on any single vessel
to comply with NFPA 70 Articles 500-504, or NFPA 70 Article 505, or IEC
60092-502, based on either the Division or the Zone method of hazardous
location classification. The commenter suggested that we amend the plan
requirements for hazardous locations in Sec. 110.25-1 to ensure the
classification method is indicated on the plans submitted for review.
We agree with this suggestion and are incorporating it into this final
rule. The extent and classification of all hazardous locations is
already required in the existing Sec. 110.25-1(i) but clearly
indicating the method of classification, Division or Zone, is important
to ensure appropriate selection of equipment for the hazardous
location. In this final rule, we amend Sec. 110.25-1(i) to require
that the plans indicate the method of classification of the hazardous
locations in addition to the other requirements already included in
paragraph (i).
Subpart 111.10--Power Supply
Sec. 111.10-9 Ship's Service Supply Transformers; Two Required
A commenter noted that our proposed revision to the note to Sec.
111.10-09 concerning ship's service transformers appears to contradict
the text of Sec. 111.10-09 regarding the number of transformers. We
disagree. Section 111.10-3 requires that the shipboard power supply
system on self-propelled vessels have at least two electric generating
sources. The intent of Sec. 111.10-09 is to continue this requirement
by duplicating the number of transformers that are used to supply the
ship's service distribution system. As explained in this note, the
intent is not to provide duplication of ship's service distribution
system circuits after the ship's service switchboard. This is a long-
standing position that is explained in Coast Guard guidance,
specifically

---------------------------------------------------------------------------
Subpart 111.12--Generator Construction and Circuits
Sec. 111.12-11 Generator Protection
Section 111.12-11(g) states that a ship's service generator and its
switchboard must be in the same space and states that a control room
inside the machinery casing is not considered outside the machinery
space. Paragraphs 111.12-11(g)(1) and (2) provide two arrangements that
the Coast Guard considers to meet this requirement. In other words, we
consider a switchboard room within the machinery space, containing the
overcurrent protection on the switchboard, to be satisfactory,
regardless of whether there are centralized engineering controls or
monitoring in that control room. This rule, which replaces a reference
to a ``semiconductor rectifier'' with ``semiconductor converter'' in
paragraph (g), does not substantively change these existing provisions.
A commenter asked if a control room that is an air-conditioned
switchboard room with generator controls on a switchboard, but without
centralized engineering control and monitoring, is an acceptable
control room. This question is beyond the scope of this rulemaking, but
questions regarding compliance with Subchapter J may be submitted to
the MSC.
Subpart 111.15--Storage Batteries and Battery Chargers: Construction
and Installation
Two commenters suggested we consider incorporating by reference
IEEE 1187-2013, ``IEEE Recommended Practice for Installation Design and
Installation of Valve-Regulated Lead Acid Batteries for Stationary
Applications.'' The commenters noted that although FPUs are not
stationary, they are not ocean-going vessels either. The commenters
also noted because FPUs do not have the range of motions of a vessel,
they use valve-regulated lead acid batteries (as governed by IEEE 1187-
2013) rather than the vented lead-acid batteries covered in the NPRM's
updates to subchapter J. We understand the unique characteristics of
FPUs may require additional options and guidance. Specifically, 33 CFR
143.120(b) and CG-ENG Policy Letter 01-13 allow alternate proposals for
floating OCS facilities. System designers may submit applications to
the MSC demonstrating that a system using valve-regulated lead acid
batteries, as governed by IEEE 1187-2013, provides an equivalent level
of safety in accordance with Sec. 110.20-1. We understand this IBR
suggestion and may consider it in a future rulemaking. Further, we find
that we cannot include this suggestion in this final rule because, in
order to add the standard and those additional requirements, we would
prefer to conduct an additional analysis of alternatives and provide
the public opportunity to review and comment on its addition.
Subpart 111.30--Switchboards
Sec. 111.30-5 Construction
In the NPRM, we proposed replacing the existing reference to
section 8.3 of IEEE 45-2002 in Sec. 111.30-5(a)(1) with a reference to
section 6 of the more recent IEEE 45.7-2012. A commenter noted section
6.3.3 of IEEE 45.7 requires a steering gear breaker trip set to not
less than 200 percent of locked rotor current. This conflicts with
Sec. 58.25-55(a)(2), which requires a trip set point between 175 and
200 percent of locked rotor current. We agree that the change we
proposed in the NPRM would present an unintended conflict with other
existing regulations. The intent of Sec. 111.30-5 is to address
switchboard construction, not overcurrent protection for specific
systems, so when reviewing IEEE 45.7 we did not observe that the
standard added a requirement for the steering gear circuit overcurrent
protection. We did not intend the NPRM to propose a change to the
existing requirements for steering gear circuit overcurrent protection.
For this reason, in Sec. 111.30-5(a)(1) of this final rule, we are
incorporating section 6 of IEEE 45.7-2012, excluding section 6.3.3.
A commenter asked for clarification of the proposed Sec. 111.30-
5(c) regarding switchboard construction, which stated that ``[t]he
interchangeability and compatibility of components complying with both
IEEE and IEC cannot be assumed.'' We agree this proposed paragraph (c)
could have caused confusion. Our intent in this paragraph was to
discourage the mixing of acceptable standards in a manner that could
result in a potentially unsafe switchboard. We recognize that complying
with and enforcing this relatively vague requirement would be
difficult, and we have accordingly deleted it in this final rule.
Switchboards should be constructed in accordance with the standards
incorporated by reference in subpart 111.30.
Sec. 111.30-19 Buses and Wiring
In the NPRM, we proposed replacing the existing reference to
section 7.10 of IEEE 45-1998 in Sec. 111.30-19(a)(1) with a reference
to section 5.10 of the more recent IEEE 45.7-2012. A commenter noted
section 5.10 of IEEE 45.7-2012 appears to have less strict requirements
for generator bus sizing and could be interpreted to not require sizing
to support overload operation of the generator for a sustained period.
We disagree. The requirements are very similar, and IEEE 45.7-2012
reflects the latest guidance on bus sizing.
Sec. 111.30-25 Alternating-Current Ship's Service Switchboards
A commenter suggested that the generator field rheostat (manual
voltage controller) currently required by Sec. 111.30-25(c)(1) was of
limited value and is not required by other regulatory bodies. We
understand this suggestion and may consider it in a future rulemaking.
In order to remove the requirement, we would prefer to conduct an
additional analysis of alternatives and provide the public opportunity
to review and comment on its removal. In the meantime, however, system
designers may submit switchboards with alternative instrumentation that
provides an equivalent level of safety to the MSC in accordance with
Sec. 110.20-1.
Subpart 111.33--Power Semiconductor Converter Systems
In the NPRM, we proposed changing the heading of subpart 111.33
from Power Semiconductor Rectifier Systems to Power Semiconductor
Converter Systems and changing references to rectifiers to converters.
This proposed change aligned with general industry practice of using
the term converter as it is more general than rectifier. This subpart
applies to rectifiers (alternating current (AC) to direct current
(DC)), inverters (DC to AC), and other power converters. Additionally,
in the NPRM we proposed updating the standards incorporated by
reference in this subpart to more recent editions. A commenter noted
that 4.31.19.12 of IEEE 45.2-2011, which would replace 10.20.12 of IEEE
45-2002, covers rectifiers. The commenter is correct in this regard.
However, 4.31.19.12 of IEEE 45.2-2011 provides the required nameplate
data, and the Coast Guard determined the requirements of this section
are also generally applicable to
[[Page 16315]]
any power semiconductor converter system.
In addition, in the NPRM, we proposed replacing references
throughout subpart J to ``semiconductor rectifier (SCR)'' with
references to ``semiconductor converter''. However, upon further review
following the NPRM's publication, we realized that some instances of
this amendment were inadvertently not included in the amendatory
language for the NPRM. We have updated the amendatory language in this
final rule to include these missed instances of ``converter'' in this
final rule at Sec. Sec. 111.33-1 and 111.33-3(b).
Subpart 111.40--Panelboards
Sec. 111.40-1 Panelboard Standard
A commenter noted Section 9.10 of IEEE 45.1, proposed for
incorporation by reference in the NPRM, includes multiple sub-sections
but only subsection 9.10.1 is directly applicable to panelboards. The
commenter suggested updating the reference to only include this
subsection. We agree, and in the interest of greater precision we
revise Sec. 111.40-1 in this rule to only reference subsection 9.10.1.
Subpart 111.50--Overcurrent Protection
Sec. 111.50-3 Protection of Conductors
A commenter noted that currently neither Sec. 111.50-3 nor Sec.
111.20-15 clearly addresses NFPA 70--National Electric Code (NEC)
requirements for transformer secondary conductor protection and
suggested that Sec. 111.50-3 should include or cite to NEC
240.21(C)(1) requirements. NEC 240.21(C)(1) explicitly states that
primary overcurrent protection is insufficient to protect secondary
conductors of delta-wye transformers. In the NPRM, we did not propose
substantive changes to these two sections beyond incorporating the more
recent editions of the standards. Adding the requirements at NEC
240.21(C)(1) to Sec. 111.50-3 would require additional analysis and
opportunity for the public to review and comment. Nevertheless, we may
consider incorporating NEC Article 240, which provides guidance for
transformer conductor overcurrent protection, in Sec. 111.50-3 in the
future.
A commenter also said that neither Sec. 111.50-3 nor Sec. 58.25
currently address DC steering gear motors. The commenter also said that
both Sec. Sec. 111.50-3 and 58.25 are silent on the use of fuses for
overcurrent protection in these systems. The commenter suggested that
we remove the cross-reference to 46 CFR 58.25 and revise Sec. 111.50-3
to align with ABS SVR 4-8-2/9.17.5 standards on DC steering gear motors
and prohibiting fuses. We disagree with the suggested change. Paragraph
58.25-55(a)(1) specifically requires DC steering gear motors to be
protected from overcurrent by a circuit breaker at the switchboard.
This section does not list fuses as an acceptable means of overcurrent
protection. Vessel owners and operators must ensure DC steering gear
motors are protected from overcurrent by circuit breakers unless an
equivalent arrangement is approved by the MSC in accordance with Sec.
110.20-1. We did not propose substantive changes to these two sections
in the NPRM beyond incorporating the more recent editions of the
standards already incorporated by reference in Sec. 111.50-3. However,
we will consider updating our steering gear motor regulations in the
future following a review of the latest advances in steering gear power
and control systems.
Subpart 111.51--Coordination of Overcurrent Protection Devices
Sec. Sec. 111.51-1 Purpose and 111.51-5 Protection of Vital Equipment
In the NPRM, we proposed to revise Sec. 111.51-1 to set out a
broad introductory discussion of the requirements for coordination of
overcurrent protection devices that is based on the recommendations in
IEC 60092-202:2016 and not substantively different from the existing
Sec. 111.51-1 that it replaced. A commenter noted the term
``continuity of service'' as used in the proposed revisions to Sec.
111.51-1, as well as in the current text of Sec. 111.51-1, is not
defined and could be interpreted in a number of ways. Additionally, the
same commenter also recommended editing Sec. 111.51-5(b)(2) to allow
for cases where multiple protective devices are directly in series due
to the arrangement of the power system and vendor equipment supply or
requirements for disconnecting device. Alternatively, they suggested we
define that a protective device refers to a set of one or more
protective devices which protect the same segment of the electrical
system. The commenter was concerned the section could be interpreted to
require explicit coordination between protective devices within the
same feeder or branch circuit.
It is not the intent of this final rule to substantively alter our
existing regulations for coordination of overcurrent protection
devices. Continuity of service is defined in IEC 60092-202:2016 as a
``condition where, after a fault in a circuit has been cleared, the
supply to the healthy circuits is re-established.'' More importantly,
the goal of overcurrent protection coordination is to minimize the
impact of short circuits on vital equipment as explained in Sec. Sec.
111.51-1 and 111.51-5. If multiple protective devices are in series, it
is incumbent on the system designer to demonstrate the devices satisfy
the intent of overcurrent protection coordination. Additionally,
proposing a unique definition for protective devices is not a preferred
option where the definition is widely used and defined by a standard.
We encourage the use of established industry standards and definitions.
If there are any vessel or system specific arrangements being proposed
for Coast Guard certificated vessels, their equivalency with this
subpart can be demonstrated to the MSC in accordance with Sec. 110.20-
1. We made no changes from the proposed rule in Sec. 111.51-5.
Subpart 111.60--Wiring Materials and Methods
Sec. 111.60-3 Cable Application (Existing)
In the NPRM, we proposed to delete this section because it is
unnecessarily prescriptive. In its place, we proposed that regulated
entities would consult the current and proposed cable construction
standards in proposed new Sec. 111.60-1 for the application of
specific types of cable. A commenter expressed concern that cable for
specialized applications, such as scientific research instruments and
passenger ferry Wi-Fi networks, is sometimes not available or cost-
prohibitive to meet the fire test requirements. The commenter
recommended retaining Sec. 111.60-3 largely as written. Based on our
research for available products, the Coast Guard has determined that
common types of cables that comply with the standards in Sec. 111.60-1
are available and provide the safest option for U.S. vessels.
Additionally, our research indicates the cost will be comparable to all
other cable suitable for marine applications. Accordingly, this final
rule retains the amendment from the NPRM to remove Sec. 111.60-3. We
will consider other cable on a case-by-case basis in accordance with
the equivalency provisions of Sec. 110.20-1.
Sec. 111.60-4 Minimum Cable Conductor Size
A commenter noted we did not propose changing the required minimum
conductor size in this section of 0.82 square millimeters (mm\2\) and
2.1 mm\2\ for control and power cable, respectively. The commenter
explained that vessels inspected under the ACP
[[Page 16316]]
have a lesser conductor size requirement. For example, ABS MVR 4-8-2/
7.7.2 allows smaller minimum conductor sizes of 0.5 mm\2\ and 1.5 mm\2\
for control and power cable respectively. (The metric dimensions given
in this section are metric conversions of the standard American Wire
Gauge sizes rather than standard metric wire sizes suggested by this
commenter and used in the ABS rule.) The commenter recommended we
decrease the metric size requirements to match the requirements
applicable to ACP vessels because they believed doing so would
eliminate the need to excessively oversize metric cable to meet rules
that are currently written to align with common AWG sizes. Vessels
enrolled in the ACP comply with a comprehensive set of engineering
standards and an inspection regime that collectively provide a level of
safety equivalent to complying solely with the regulations in 46 CFR
even though the requirements are not identical. As the commenter noted,
we did not propose substantive changes to this section in the NPRM and
do not intend to change it in the final rule. Allowing smaller minimum
conductor sizes on all vessels regulated by subchapter J is a less
stringent requirement that we may consider in the future following
additional analysis and opportunity for public comment. Presently, the
metric conductor size requirements in this section are still considered
reasonable and safe, and we made no additional changes based on this
recommendation.
Sec. 111.60-6 Fiber Optic Cable (Existing)
In the NPRM, we proposed to remove current Sec. 111.60-6 because
fiber optic cable that complies with Sec. 111.60-1 is now available. A
commenter contended that such fiber optic cable is not readily
available. We agree that it may be difficult to find fiber optic cable
to meet the standards in Sec. 111.60-1 and have decided to forgo the
proposed change to remove Sec. Sec. 111.60-2 and 111.60-6. This final
rule does not remove existing Sec. Sec. 111.60-2 and 111.60-6, or the
cross references to Sec. Sec. 111.60-2 and 111.60-6 within the
applicable list of standards incorporated by reference in Sec. Sec.
110.10-1(j)(14), 110.10-1(q)(23), 110.10-1(k)(34), 110.10-1(k)(35), and
110.10-1(j)(13), where they were already included. However, in this
final rule we have updated the standards mentioned within Sec. Sec.
111.60-2 and 111.60-6 to conform with updates to standards incorporated
by reference within this subchapter.
Sec. 111.60-11 Wire
A commenter noted the reference to Section 5.7 of IEEE 45.8-2016 in
Sec. 111.60-11 and pointed out that this section does not address
wire. We agree and have removed the reference to Section 5.7 of IEEE
45.8 from this section because it is not related to the topic of Sec.
111.60-11. The commenter also suggested that wire constructed to a
recognized commercial standard or military specification MIL-W-16878 or
MIL-W-22759, with particular attention to the effects of vibration,
moisture, ambient temperature, and other adverse conditions such as
contaminants and oils that may be present should be acceptable. We
agree in principle. Section 111.60-11(c) provides that wire must the
requirements set out in one of three standards for wire and concludes
with ``or equivalent standard.'' System designers choosing an
alternative standard they believe equivalent, such as that described by
the commenter, should discuss it with the MSC. There are too many
relevant standards to incorporate them all. Instead, we have decided to
offer three standards as guidance for acceptable wire requirements. We
will consider equivalency requests in addition to the standards we
incorporate by reference.
Subpart 111.70--Motor Circuits, Controllers, and Protection
Sec. 111.70-3 Motor Controllers and Motor-Control Centers
A commenter noted that the proposed regulatory text in the NPRM
implied that we were making changes to Sec. Sec. 111.70-3(c)(2) and
(d)(1)(v) but the proposed regulatory text as presented in the NPRM was
unchanged from existing regulatory text. This observation is correct.
We erroneously included these sections in the NPRM's amendatory
instructions, but we did not actually propose any changes. No changes
were intended. This final rule does not include any amendments to the
regulatory text at Sec. Sec. 111.70-3(c)(2) and (d)(1)(v).
Subpart 111.75--Lighting Circuits and Protection
Sec. 111.75-17 Navigation Lights
In the NPRM, we proposed incorporating EN 14744 in Sec. 111.75-17
as an additional alternative standard for navigation lights. Currently,
UL 1104 is the only standard incorporated by reference in Sec. 111.75-
17. One commenter suggested that, since UL 1104 is no longer supported
by UL and does not address electromagnetic interference or light-
emitting diode (LED) light lifecycle degradation, it should be removed
from this section and EN 14744 should be adopted as the sole standard
for all navigation lights, including AC- and DC-powered lights,
incandescent and non-incandescent lights, lights on all vessel types
and sizes, and lights on inspected and non-inspected vessels.
We disagree with the suggestion to remove UL 1104. Several years
ago, UL transferred responsibility for the maintenance of UL 1104 to
the American Boat and Yacht Council (ABYC). Prior to this rulemaking,
UL 1104 was the only standard for the construction and testing of
navigation lights incorporated by reference in subchapter J, and it is
currently being used by several navigation light manufacturers. Lights
manufactured and certified to UL 1104 meet the current luminous
intensity and colorimetric requirements of the International
Regulations for Preventing Collisions at Sea, 1972 (1972 COLREGS).
Additionally, the environmental performance requirements contained in
UL 1104 are similar in intent to those in EN 14744. For these reasons,
we are not removing UL 1104 at this time.
Additionally, we cannot incorporate by reference EN 14744 for all
light and vessel types as suggested. The scope of this rule is limited
to subchapter J. The navigation light requirements in subchapter J
generally apply to larger, inspected commercial vessels. The
requirements for navigation lights on certain smaller, inspected
commercial vessels, uninspected commercial vessels, and recreational
vessels are contained in other subparts of the CFR. We did not propose
amendments to those subparts in the NPRM, and because of this we cannot
incorporate by reference EN 14744 for all light and vessel types.
Since UL transferred UL 1104 to ABYC we have worked with ABYC and
other navigation light stakeholders to develop an updated navigation
light standard to replace UL 1104. This standard, ABYC C-5,
Construction and Testing of Electric Navigation Lights, published in
July 2021, too late for inclusion in the NPRM and after the NPRM
comment period closed. ABYC C-5 is applicable to all light and vessel
types and addresses both electromagnetic interference and LED light
lifecycle degradation. We may address the incorporation by reference of
ABYC C-5, a broader incorporation by reference of EN 14744, other
potential navigation light standards, and navigation light requirements
for all vessel types in a future, broader, Coast Guard proposal.
[[Page 16317]]
Subpart 111.83--Shore Connection Boxes
Sec. 111.83-7 High Voltage Shore Connection
A commenter noted that proposed new Sec. 111.83-7 only applies the
requirements of IEC/IEEE 80005-1:2019 to vessels required by law to
have high voltage shore connections (HVSCs), and recommended removing
that limitation. The Coast Guard agrees the proposed limitation to only
vessels that were required by state or local law to connect to HVSC
would have created unnecessary confusion. This section does not require
compliance with IEC/IEEE 80005-1:2019; it is a recommendation for best
practices and additional safety. For vessels that connect to electrical
shore power using an HVSC, we recommend complying with IEC/IEEE 80005-
1:2019 regardless of whether it is required by a state or local
jurisdiction. For this reason, we have removed the limitation that
Sec. 111.83-7 would only apply to vessels required by law to have
shore power and instead provide this section as a recommended standard
for all vessels that use an HVSC.
Another commenter requested that the ABS Guide for High Voltage
Shore Connection be considered for incorporation by reference as an
alternative standard for HVSCs. We have not incorporated this guide.
IEC/IEEE 80005-1:2019, which is incorporated by reference in the new
Sec. 111.83-7, is an international voluntary consensus standard that
provides an acceptable baseline recommendation, while the ABS Guide for
High Voltage Shore Connection is a classification society guide.
Although the ABS Guide for High Voltage Shore Connection may be a
satisfactory alternative for consideration in an equivalency request,
it is not necessary to list a classification society guide in the
regulations when an international voluntary consensus standard is
available. The National Technology Transfer and Advancement Act of 1995
(15 U.S.C. 272 note) directs Federal agencies to use voluntary
consensus standards in their regulatory activities unless doing so
would be inconsistent with applicable law or otherwise impractical.
Subpart 111.99--Fire Door Holding and Release Systems
Sec. 111.99-5 General
The NPRM proposed updating the existing citation in Sec. 111.99-5
to reflect a more current edition of the International Convention for
Safety of Life at Sea, 1974 (SOLAS), Sixth edition. A commenter noted
that SOLAS II-2/9.4.1.1.5 includes a number of paragraphs that include
requirements for safe functioning of the fire door release system. The
commenter suggested that we expand Sec. 111.99-5 to include these
additional paragraphs in II-2/9.4.1.1.5 beyond that which was
referenced in the NPRM. We understand that SOLAS contains additional
requirements for fire doors. Vessels that comply with SOLAS must meet
these requirements, but requiring all vessels that must comply with
Subchapter J's requirements meet these standards would place regulatory
requirements on these vessels without providing appropriate opportunity
for public notice and comment. Accordingly, we did not incorporate this
suggestion at this time.
Subpart 111.105--Hazardous Locations
One commenter suggested we remove the Division system for
classification of hazardous locations from subchapter J. The commenter
said that compliance would be simpler if only the Zone system was
accepted. We disagree. This is an established system used extensively
in North America and removing the Division system would adversely
affect many equipment manufacturers.
Another commenter requested we incorporate by reference American
Petroleum Institute (API) standards API RP 14FZ and API RP 500, and
IEEE 1187-2013. As we discussed in regard to a comment on subpart
111.15, we are not inclined to incorporate IEEE 1187 because it
contains additional requirements beyond what we believe necessary to
incorporate at this time. API RP 14FZ and API RP 500 are already
incorporated or will be incorporated in a very limited scope, which we
have determined to be a reasonable level at which to require these
standards.
Sec. 111.105-3 General Requirements and System Integrity
The intent of Sec. 111.105-3 is to ensure all electrical equipment
installed in a hazardous location is appropriate for the location. One
commenter suggested that acceptable electrical components may be
combined in a manner that may produce an assembly that can ignite a
hazardous atmosphere and that this may not be caught in after-
installation inspections. The commenter suggested several standards to
address this concern, such as ANSI/UL 698A, IEC TS 60079-46, ANSI/UL
508A, and UL 2011. Additionally, the commenter suggested that this rule
address the importance of assembly verification throughout the
equipment lifecycle from design to installation. Assembly verification
throughout the process is an important issue for system designers, but
it is outside the scope of this rulemaking. Applicants must include
assemblies of electrical equipment in plans and installation details in
their request for Coast Guard review in accordance with Sec. Sec.
110.25-1(i) and (j). The Coast Guard then reviews the plans and
installation details to ensure safe assembly in accordance with these
standards.
Several commenters requested clarification of the phrase ``and not
in combination in a manner that will compromise system integrity or
safety,'' proposed in the NPRM for new Sec. 111.105-3(c).
Additionally, commenters suggested that we reorganize Sec. 111.105-3
to better separate equipment selection standards and installation
requirements. Since its initial adoption in 1996, our intentions in
Sec. 111.105-5 (which we had proposed to move into Sec. 111.105-3)
have been to ensure that proper and safe equipment is used in hazardous
locations and to allow safe combinations of equipment complying with
either NFPA 70 (Division system) or the IEC 60079 series of standards
(Zone system).\3\ The phrase in question, located in Sec. 111.105-3(c)
in this final rule, ensures such systems are carefully designed because
the methods of classification of hazardous locations can differ. When a
location is subject to two classification systems, it may have two
different classifications. For example, a specific cargo oil tank may
be classified as a Class I, Division 1, location under one system and
Zone 0 under the other. In this example, electrical equipment approved
for Class I, Division 1 (intrinsically safe) or approved for Zone 0
(ia) may be installed in the cargo tank.
---------------------------------------------------------------------------
\3\ ``Electrical Engineering Requirements for Merchant Vessels''
interim rule (61 FR 28284, June 4, 1996).
---------------------------------------------------------------------------
In the NPRM we proposed to combine Sec. Sec. 111.105-3 and
111.105-5 into Sec. 111.105-3 to be consistent with Sec. Sec.
111.106-3 and 111.108-3. This created confusion among commenters, and
we have decided to revise our approach to proposed Sec. 111.105-3.
Instead, we have renumbered the proposed Sec. 111.105-7 as Sec.
111.105-3 and amended it to be more consistent with Sec. Sec. 111.106-
3 and 111.108-3 by adding notes after new paragraphs 111.105-3(b)(1)
and (b)(2). This change better clarifies the appropriate guidance for
using Zone equipment in Division-designated spaces or using Division
equipment in Zone-designated spaces.
[[Page 16318]]
Additionally, as mentioned earlier, we will also require in Sec.
110.25-1(i) that applicants clearly indicate the hazardous location
method of classification, Division or Zone, in their plan submissions.
One comment suggested that it was more appropriate to incorporate
by reference Clause 7 rather than Clause 6 of IEC 60092-502 in Sec.
111.105-3(b). We disagree. Clause 6 concerns the requirements of
electrical equipment in hazardous areas while Clause 7 addresses
installation of electrical equipment in hazardous areas. The intent of
Sec. 111.105-3(b) is to prescribe the standards for electrical
equipment intended for hazardous areas (locations), not specifically
installation. This is the same as Sec. 111.108(a)(3). It was not our
goal for the proposed modifications to Sec. 111.105 to substantively
change the standards fundamental to equipment selection. In the
existing regulations, in accordance with Sec. 111.108-1(b), all
vessels could use the standards specified in 46 CFR Subpart Sec.
111.108. Revisions to Sec. 111.105 are intended to make this clearer.
One comment noted that for electrical installations on mobile and
fixed offshore units the proposed requirements only reference Clause 8
of IEC 61892-7. The commenter also noted that Clause 8 excludes
guidance on cables and conduits and Clause 9 of IEC 61892-7 is for
cables and wiring systems. This is correct. We intentionally did not
reference Clause 9 for cables and wiring systems. Prior to this
rulemaking, we previously incorporated Clause 6 of IEC 61892-7:2007.
Clause 6 addresses electrical equipment in hazardous areas, but not
wiring or cable systems. We proposed to incorporate by reference the
more recent Clause 8 of IEC 61892-7:2019. Clause 8 similarly addresses
electric equipment by referencing Clause 5 of IEC 60079-14:2013. It was
not our intent to add wiring and cabling system requirements to Sec.
111.105-3. The requirements for wiring and cable systems in hazardous
locations are in Sec. 111.105-17.
One commenter noted that both Clauses 8 and 9 of IEC 61892-7
reference IEC 60079-14, Electrical installations design, selection, and
erection, and suggested that we should incorporate IEC 60079-14 by
reference. We disagree with the suggestion. Since we incorporated by
reference IEC 61892-7:2007 in 46 CFR subchapter J, the standard has
evolved and been updated twice. In 2014, the IEC 61892-7 requirements
for installations in hazardous area were rewritten based on the
requirements of IEC 60079-14:2013. In the latest edition, 2019, IEC
61892-7 was completely rewritten and references are, to the extent
possible, made to IEC 60079-14:2013 and to other relevant standards. At
this time our intent is to only apply IEC 60092-14:2013 as it is
referenced in Clause 8 of IEC 618792-7:2019. We describe Clause 8 in
the previous paragraph. Despite the commenter mentioning Clause 9 of
IEC 61892-7:2019, we did not propose to incorporate it in the NPRM. We
already address the cable and wiring requirements using standards we
deem sufficient in Sec. 111.105-17. It is commonplace for standards to
reference other standards, but incorporating every standard simply
because it is cross-referenced would cause us to incorporate more
standards than are reasonably necessary to convey the relevant
requirements. A broader incorporation by reference of IEC 61892-7:2019
would require additional regulatory analysis and an additional
opportunity for the public to review and comment.
Sec. 111.105-28 Internal Combustion Engines
A commenter said that Sec. 111.105-28 states ``Internal combustion
engines installed in Class I Divisions 1 and 2 (Zones 1 and 2),'' but
there is no direct equivalency between Class I Division 1 and Zone 1 as
Class I Division 1 covers equipment in Zone 0 as well. The commenter
suggested that references to Class I Divisions (1 and 2) and Zones be
removed from the section. We disagree with this suggestion. Currently,
Sec. 111.108-1(b) allows U.S. Mobile Offshore Drilling Units (MODUs),
floating OCS facilities, and vessels other than Offshore Supply Vessels
(OSVs) regulated under 46 CFR subchapter L and U.S. tank vessels that
carry flammable and combustible cargoes, to comply with ASTM F2876 per
Sec. 111.108-3(g). Our purpose in changing Sec. 111.105 is to improve
the consistency of the regulations related to hazardous areas in
Sec. Sec. 111.105, 111.106, and 111.108. It does not change the
requirements. Although we agree with the commenter's assertion that
Class I Division I may also cover equipment in IEC Zone 0, internal
combustion engine installations are generally prohibited for use in
shipboard IEC Zone 0 areas.
A commenter noted that engines may be certified by the manufacturer
to ASTM F2876 and its maximum surface temperature requirements. The
commenter also noted that ASTM F2876 does not address different testing
requirements from Zone 1 and Zone 2 applications. The primary purpose
of ASTM F2876 is determining the maximum operating temperature of the
engine, in order to ascertain the suitability of the engine
installation in hazardous areas associated with the autoignition
temperature of various flammable cargoes. An independent laboratory
must certify all electrical equipment associated with the engine
installation. Although ASTM F2876 contains other requirements in
addition to temperature measurement, the references to EN 1834-1 within
ASTM F2876 are recommendations only.
Sec. 111.105-50 Alternative Standard to the Classification of
Hazardous Locations Requirements of This Subchapter
A commenter noted we proposed in the NPRM to incorporate IEC 60092-
502 without also incorporating the Coast Guard's interpretations and
additional requirements, issued in April 2009, which we maintain on the
Coast Guard's website for the ACP.\4\ The commenter did not offer an
opinion or recommendation on this proposal, but asked us to clarify if
these requirements in the IEC 60092-502 Supplement would be obsolete
when we incorporate IEC 60092-502:1999. The intent of these
interpretations and supplemental requirements was for vessels in the
ACP to achieve equivalency with the regulations in 46 CFR. The Coast
Guard has determined that IEC 60092-502, even without these
interpretations and supplemental requirements, is a satisfactory
alternative method for the classification of hazardous locations. When
using IEC 60092-502 to classify hazardous locations, vessels no longer
need to comply with our IEC 60092-502 Supplement issued in April 2009.
---------------------------------------------------------------------------
\4\ See U.S. Coast Guard Interpretation: IEC 60092-502:1999
Supplement at https://www.dco.uscg.mil/Portals/9/DCO%20Documents/5p/5ps/Alternate%20Compliance%20Program/iec60092-502sup.pdf.
---------------------------------------------------------------------------
A commenter said that our proposed incorporation by reference of
IEC 60092-502:1999 as an alternative method for classification of
hazardous location, while also referencing Sec. Sec. 32.60-20(c) and
38.20-10, resulted in conflicting ventilation requirements. We agree
that they can be conflicting. Unfortunately, existing U.S. and
international requirements for cargo pump room ventilation are
different. Sections 32.60-20(c) and 38.20-10 both require an air change
every 3 minutes (20 air changes per hour) while Clause 8.1.3 of IEC
60092-502:1999 requires an air change every 2 minutes (30 air changes
per hour). We intend for IEC 60092-502:1999 to be an alternative to
existing regulations. At this time we are not changing 46 CFR
subchapter D, including Sec. Sec. 32.60-20(c) and 38.20-10,
[[Page 16319]]
nor modifying IEC 60092-502. System designers choosing to use IEC
60092-502:1999 for classification of hazardous locations must follow
the standard. However, we are revising Sec. 111.105-50(c) from what
was proposed in the NPRM to clearly state when 30 air changes per hour
are required. Specifically, if IEC 60092-502:1999 is used, cargo
handling rooms and other spaces where hazardous location classification
is dependent upon ventilation must have mechanical ventilation capable
of at least 30 air changes per hour, based upon the gross volume of the
space.
Subpart 112.05--General
Sec. 112.05-5 Emergency Power Source
Section 112.05-5(a) requires that an emergency power source have
the capacity to simultaneously supply all loads connected to it. To
further clarify this, in the NPRM we suggested adding the phrase ``at a
unity (1.0) service factor.'' This simply means the emergency power
source must be sufficiently sized to operate all loads at their full
rated capacity.
A commenter requested we modify the required capacity of the
emergency power source with a phrase such as ``with due regard being
paid to such services as may have to be operated simultaneously.'' They
stated that their proposed change would allow use of emergency
generators that are more closely sized to the loads that would be
needed in an emergency. We disagree with the commenter's proposed
change. It would change the intent of the existing regulation by
allowing more discretion and ambiguity than a specific load capacity
measurement. In the interest of providing a clear discernable standard
that we considered safe, we will proceed with requiring the unity 1.0
service factor as proposed in the NPRM.
In table 1 to Sec. 112.05-5 footnote 2, we are replacing the
reference to Sec. 111.93 with a reference to Sec. 58.25-65 because we
moved the requirements in Sec. 111.93 to Sec. 58.25-65 in a previous
rulemaking (60 FR 24776, May 10, 1995). Although we did not include
this amendment in the NPRM, this is a conforming edit that will not
have an impact on the existing emergency power requirements.
Sec. 112.05-7 Use of Emergency Generator in Port
A commenter noted that existing Coast Guard policy regarding in
port use of the emergency generator requires that a qualitative failure
analysis (QFA), design verification test procedure (DVTP), and a
periodic safety test procedure (PSTP) be submitted for review, but the
proposed Sec. 112.05-7 did not have this requirement. This is correct.
The requirements for these documents are contained in 46 CFR subchapter
F Subpart 61.40. Based on this subpart, an emergency generator intended
to meet Sec. 112.05-7 for use in port would be required to submit a
QFA, DVTP, and PSTP for review. We do not see the need to duplicate
this requirement in Sec. 112.05-7.
A commenter said we could require more comprehensive alarms in
Sec. 112.05-7(c) and requested that, at a minimum, we consider
clarifying the alarms and shutdowns required versus the shutdowns
allowed or disallowed. We understand the commenter's intent and request
for more specific information, but this regulation provides the
baseline requirements. We do not agree with revising the regulation to
require additional alarm regulations at this time because we have
determined that the baseline alarm requirements are still adequate.
A commenter noted that the proposed regulations regarding in-port
use of the emergency generator at Sec. 112.05-7(c) require the vessel
be equipped with displays and alarms in the centralized control station
and alarm monitoring at the engineers' quarters. The commenter pointed
out that not all ships have a centralized control station or alarm
summary panels in the crew's quarters. These regulations set the
baseline requirements for in-port use of the emergency generator. If a
system designer cannot meet the requirements due to unique ship
characteristics, the designer may propose equivalent arrangements to
the MSC in accordance with Sec. 110.20-1. Our intent for these alarm
location regulations is to require alarms both where the emergency
generator is normally controlled and where crew would normally be
located in port.
Additionally, two commenters noted that the NPRM did not discuss
arrangements for feedback to power the vessel's main switchboard for
habitability services and any special load analysis considerations or
interlocks requirements for paralleling with main generators. Following
our review, we find that there is not a need to include provisions on
these points because the existing Sec. 112.05-3(c) and the new Sec.
112.05-7(g) both address use of the emergency generator to feedback to
non-emergency loads and require either disconnection or automatic load
shedding of these loads before the emergency generator is overloaded.
Another commenter was concerned that Sec. 112.05-7(e) appeared to
be describing requirements for breaker coordination to main services
while using the emergency generator in port. This is true, and this
coordination is not a new requirement. Subpart 111.51 requires
coordinated protection and selective operation of overcurrent
protective devices for all potential plant configurations, including
this situation. Section 112.05-7(e) clarifies that in port use of the
emergency generator is one of the configurations requiring coordination
of overcurrent devices in accordance with Sec. 111.51-5(a). Per the
requirements of this rule, the power supply circuits for the use of an
emergency generator in port must be arranged and protected to ensure
that any electrical fault (except for the emergency generator and the
emergency switchboard) will not affect the operation of the main and
emergency services. The commenter was concerned this requirement could
be interpreted to require full breaker coordination, which they believe
is not feasible on many vessels with large distribution breakers from
the main switchboard not designed to coordinate with a small power
source such as the in-port generator. The commenter requested we remove
references to protecting the main power system while using emergency
generator in port from these regulations, noting that the intent of the
rule is to ensure the availability of the emergency power system if it
is being used as the power source while in-port. We understand the
commenter's concerns, but, as explained in Section V.E, this provision
has been accepted by IMO since 2005 and is similarly addressed in
classification society rules. It is true that many of the provisions in
this section are aimed at ensuring the availability of the emergency
generator in port, but it is also important that the power circuits for
the main distribution system are appropriately protected when powered
by the emergency generator. We recognize that full coordination may not
always be possible because of the large variation in short currents due
to different operational conditions, but the coordination study must
demonstrate main power system circuits connected to the emergency
generator in port are adequately protected against short circuit. For
these reasons we did not make any changes to the regulatory text
originally proposed for Sec. 112.05-7.
Subpart 112.15--Emergency Loads
Sec. 112.15-1 Temporary Emergency Loads
As provided in the NPRM, in Sec. 112.15-1 we will now require an
engineer's assistance-needed alarm as a
[[Page 16320]]
required temporary emergency load. A commenter correctly noted that
adding the alarm as a temporary emergency load meant that it would also
be a final emergency load. This is correct. In accordance with Sec.
112.15-5(a), temporary emergency loads are also final emergency loads.
Regulatory Analysis Comments
A commenter asserted that table 3, ``Affected U.S.-Flagged Vessel
Population That Complies with 46 CFR Subchapter J,'' on page 21462 of
the NPRM, does not provide enough clarity to determine whether floating
OCS facilities are excluded or included under the vessel count for
``Cargo and Miscellaneous Vessels.'' The commenter also encouraged the
Coast Guard to make changes to the Marine Information for Safety and
Law Enforcement (MISLE) database and Coast Guard documentation to
ensure this and future rulemakings clarify whether floating OCS
facilities are included or excluded.
Another commenter expressed a concern regarding table 3, suggesting
that, despite what may be currently listed in MISLE, the latest tally
of U.S.-flagged MODUs is less than 5, and likely comprises only the
Helix Q4000 and Enterprise Offshore Drilling's EOD 201, and possibly
the Spartan Rigs 202 and 303. The commenter suggested we revise table 3
of the proposed rule to read ``<5'' to more accurately reflect the
scope of subchapter J's application to U.S.-flagged MODUs.
We agree with these commenters' assertions that we incorrectly
counted the number of Cargo and Miscellaneous Vessels. Our MISLE
database listed floating production systems as being inspected under
Title 46 of the CFR, subchapter I-A. This is incorrect. As a result, we
overstated the number of MODUs in the regulatory analysis (RA) for the
proposed rule, which lowered the population of vessels in the ``Cargo
and Miscellaneous Vessels'' category for the final rule. After further
analysis, we revised the population of MODUs to one: the Helix Q4000.
This is the only MODU in our MISLE database. Therefore, the number of
MODUs for the final rule is one because we incorrectly classified the
rest based on the subchapter inspection field in MISLE. We added the
population of 41 floating production systems in our MISLE database to
the final rule RA's category of ``Cargo and Miscellaneous Vessels''
inspected under subchapter I, which we present in table 4 of the RA.
The number of vessels in this category increased from 576 in the
proposed rule to 617 in the final rule. Because we updated the entire
vessel population for this final rule, the total number of vessels
increased from 5,570 in the proposed rule to 5,602 (see table 4).
V. Discussion of the Rule
A. Revisions to Sec. 110.10-1 Incorporation by Reference
The standards that are incorporated by reference in subchapter J
are listed in Sec. 110.10-1. With this rule, the Coast Guard updates
the technical standards to reflect more recent editions of the
standards available to the public. We encourage the use of these
updated standards because they reflect the best available technologies,
practices, and procedures that are recommended by consensus bodies and
other groups with experience in the industry. As the baseline upon
which other standards, rules, and equivalency requests are evaluated,
it is important that subchapter J incorporates up-to-date references.
We incorporate by reference the class rules of ABS, in particular,
in multiple locations within subchapter J and throughout 46 CFR Chapter
I. It is important to note that while these rules set the regulatory
baseline or standard for specific engineering systems and equipment,
the Coast Guard also designated several other authorized classification
societies in accordance with 46 CFR part 8. These classification
societies are listed on the Coast Guard website.\5\ The Coast Guard
authorized the listed classification societies to perform certain
functions and certifications using their respective class rules on
vessels enrolled in the ACP. Vessels not enrolled in the ACP may
propose using the class rules of an authorized classification society
as an alternative to the ABS class rules incorporated by reference for
particular engineering systems and equipment in accordance with Sec.
110.20-1.

---------------------------------------------------------------------------
Throughout Sec. 110.10-1, we also add additional standards to
provide alternative compliance options, remove outdated standards, and
clarify existing requirements. Where applicable, we update the naming
format, mailing addresses, phone numbers, and URL addresses for the
standards already incorporated by reference. These updates will ensure
that the standards are reasonably accessible to the public.
Following this paragraph, we list the standards we are updating,
adding, or deleting in Sec. 110.10-1. Within each standard listed, we
describe the topics covered by the standard, the changes to the
standard, any differences between currently incorporated IBR standards,
and a list of the subparts or sections that reference the IBR standard.
If this rule does not make any changes to a standard that is currently
incorporated by reference, the standard will not be discussed in the
revisions to Sec. 110.10-1. However, it will be included, without
change, in the regulatory text of Sec. 110.10-1 that appears at the
end of this document.
ABS Rules for Building and Classing Marine Vessels (ABS
Marine Vessel Rules), 2020. The rules contain a comprehensive set of
construction and maintenance requirements for ships and offshore
facilities. The rules are, in general, developed by the International
Association of Classification Societies (IACS) and by ABS staff, and
reviewed and approved by committees made up of naval architects, marine
engineers, shipbuilders, engine builders, steel makers and by other
technical, operating, and scientific personnel associated with the
worldwide maritime industry. Because of classification society rules'
comprehensive nature and ABS's long history of ensuring vessel safety
and seaworthiness, they are a valuable supplement to the numerous
voluntary consensus standards incorporated by reference. In subchapter
J the rules provide an option for the design of engineering systems and
components including generators, semiconductor rectifiers, and electric
propulsion systems. Specifically, we currently reference the 2003
edition in Sec. Sec. 110.15-1(b), 111.01-9(b), 111.12-3, 111.12-5,
111.12-7(a) and (b), 111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n),
111.105-39 introductory text and (a), 111.105-40(a) and (c), and
113.05-7(a). In 2020, ABS transitioned from the ABS Steel Vessel Rules
to the ABS Marine Vessel Rules. This allowed ABS to consolidate several
rules into one foundational rule. We incorporate by reference the 2020
ABS Marine Vessel Rules in the aforementioned sections and additionally
in the new Sec. 112.05-7(c) related to use of emergency generators in
port. The ABS Marine Vessel Rules undergo an annual review and approval
process by ABS technical committees. The Coast Guard participates on
these committees, which are comprised of international experts with
relevant experience. We are incorporating by reference the following
parts of the ABS Marine Vessel Rules: Parts 1, 2, 3, 4, 5A, 5B, 5C, 5D,
6, and 7. Several of the sections of the ABS Marine Vessel Rules that
we incorporate
[[Page 16321]]
by reference have been individually updated. For example:
[cir] ABS Marine Vessel Rules 4-8-3/Table 2: This table specifies
minimum degrees of protection for electrical equipment. This updated
table contains several technical updates since the 2003 edition,
including additional notes concerning areas protected by fixed water-
spray or water mist fire extinguishing systems, and equipment subject
to water splash.
[cir] ABS Marine Vessel Rules 4-8-3: We reference this section for
generator construction requirements. The updated edition contains
technical updates to account for changes in technology since the 2003
edition.
[cir] ABS Marine Vessel Rules 4-8-5/5.17.9: This section regarding
semiconductor rectifiers now requires a high temperature alarm.
[cir] ABS Marine Vessel Rules 4-8-5/5.5: This edition contains
updates to propulsion generator requirements.
[cir] ABS Marine Vessel Rules 4-8-2/9.17: This edition updates the
requirements for protection of motor circuits to address athwartship
thruster motor load alarms and more clearly defines the systems
requiring undervoltage release.
[cir] ABS Marine Vessel Rules 4-8-3/5: This updated section
regarding switchboards and motor controllers contains additional cable
connection requirements, optional alternative creepage and clearance
distances, and additional requirements on battery and uninterruptible
power systems based on advancements in technology.
[cir] ABS Marine Vessel Rules 5-10-4/3: This section regarding
roll-on/roll-off cargo spaces is now titled 5C-10-4/3. The new edition
made updates to ventilation requirements and to the tables of dangerous
goods.
[cir] ABS Marine Vessel Rules 4-9-7/Table 9: This table regarding
equipment testing is now titled 4-9-8/Table 1. The updates to this
table reflect changes in technology and industry testing practices.
ABS Rules for Building and Classing Mobile Offshore Units
(ABS MOU Rules), Part 4 Machinery and Systems, 2020. The rules contain
a comprehensive set of construction and maintenance requirements for
mobile offshore drilling units. In subchapter J the rules provide an
option for the design of engineering systems and components including
generator, semiconductor rectifier, and electric propulsion systems.
Specifically, we currently reference the 2001 edition in Sec. Sec.
111.12-1(a), 111.12-3, 111.12-5, 111.12-7(c), 111.33-11, 111.35-1, and
111.70-1(a). In 2020, ABS transitioned from the ABS Mobile Offshore
Drilling Units Rules to the ABS MOU Rules. This allowed ABS to
consolidate several rules into one foundational rule. By means of this
rule, we incorporate by reference the 2020 ABS MOU Rules. Like the ABS
Marine Vessel Rules, the ABS MOU Rules will undergo a regular review
and approval process by the ABS technical committees comprised of
international experts with relevant experience. ABS updated and changed
the title of several of the ABS MOU rules incorporated by reference in
these sections. For example:
[cir] ABS MOU Rules 4-3-4 (renamed ABS MOU Rules 6-1-7): We
reference this section regarding generator construction requirements.
ABS made several technical updates since the 2001 edition to account
for changes in technology.
[cir] ABS MOU Rules 4-3-4/3.5.3 (renamed 6-1-7/12): We reference
this section for semiconductor converters requirements. ABS made
several updates to the standard due to changes in technology.
[cir] ABS MOU Rules 4-3-4/7.1 (renamed 6-1-7/9.9): We reference
this section regarding bus bars and wiring requirements. ABS made
several updates to the section since the 2001 edition.
ANSI/IEEE C37.12[dash]1991--American National Standard for
Alternating Current (AC) High-Voltage Circuit Breakers Rated on a
Symmetrical Current Basis-Specifications Guide. We remove this standard
from Sec. 111.54-1 because IEEE changed the title and republished it
with updates in 2008 as IEEE C37.12-2008--IEEE Guide for Specifications
of High-Voltage Circuit Breakers (over 1000 V), 2008. This represented
a complete technical revision of the standard. IEEE subsequently
revised it again in 2018. We incorporate by reference IEEE C37.12-2018
in Sec. 111.54-1 and further discuss this standard with the other IEEE
standards incorporated by reference.
ANSI/IEEE C37.27-1987 (IEEE 331)--Application Guide for
Low-Voltage AC Nonintegrally Fused Power Circuitbreakers (Using
Separately Mounted Current-Limiting Fuses). We remove the reference to
this standard in Sec. 111.54-1 because this guide was replaced by IEEE
C37.27--2015--IEEE Guide for Low-Voltage AC (635 V and below) Power
Circuit Breakers Applied with Separately-Mounted Current-Limiting
Fuses, 2015. We discuss this standard, IEEE C37.27--2015, with the
other IEEE standards incorporated by reference.
ANSI/ISA-RP12.06.01-2003--Recommended Practice for Wiring
Methods for Hazardous (Classified) Locations Instrumentation Part 1:
Intrinsic Safety. This recommended practice provides guidance on
installation of intrinsically safe systems for use in hazardous
(classified) locations. It clarifies and explains the requirements of
Articles 504 and 505 of NFPA 70 (National Electrical Code). This
recommended practice supersedes ISA RP 12.6-1995. By means of this
rule, we delete ISA RP 12.6 from reference in Sec. 111.105-11 and
replace it with ANSI/ISA-RP12.06.01-2003.
ANSI/ISA 12.12.01-2015--Nonincendive Electrical Equipment
for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2
Hazardous (Classified) Locations. The purpose of this standard is to
provide minimum requirements for the design, construction, and marking
of electrical equipment or parts of such equipment for use in Class I
and Class II, Division 2 and Class III, Divisions 1 and 2 hazardous
(classified) locations. This newer edition of the standard replaces
ANSI/ISA 12.12.01-2012, which the Coast Guard recently added to Sec.
111.108-3(b) as part of a separate rulemaking titled ``Electrical
Equipment in Hazardous Locations'' (80 FR 16980, Mar. 31, 2015).
Additionally, we include ANSI/ISA 12.12.01-2015 in Sec. Sec. 111.105-
3(b) and 111.106-3(b) as another certification option for electrical
equipment in hazardous location. The 2015 edition contains minor
technical changes from the 2012 edition.
ANSI/ISA-60079-18--Explosive atmospheres--Part 18:
Equipment protection by encapsulation ``m'', Third Edition, 2012. This
standard gives the specific requirements for the construction, testing,
and marking of electrical equipment and parts of electrical equipment,
and for the designation of explosion-protected electrical apparatus
complying with IEC standards (Ex) components (which is part of an
electrical equipment module found in the European hazardous area
scheme) with the type of protection encapsulation ``m'' intended for
use in explosive gas atmospheres or explosive dust atmospheres. We

2.0 (2007) of this standard in Sec. 111.108-3(b). By means of this
rule, we update
[[Page 16331]]
the reference in Sec. 111.108-3(b) to the more recent edition 4.0
(2019) and insert new references to this standard in Sec. Sec.
111.105-1, 111.105-3(b), and 111.105-17(b). The standard has been
completely rewritten. The Explosion Protection Level concept has been
introduced as an alternative risk-based classification method and the
requirements for installations in hazardous conditions reference IEC
60079-14 and other relevant standards, as appropriate. The
incorporation of this standard into subpart 111.105 provides an
alternate standard for classifications for hazardous locations.

Edition 2.0, 2019-03. This standard describes the design, installation,
and testing of HVSC systems, on board the ship and on shore, to supply
the ship with electrical power from shore. Ships may be required by
state or local laws to connect to high voltage shore power (over 1000
V) rather than running their onboard generators. Some ships may
voluntarily connect to an HVSC. In Sec. 111.83-7, we provide this
standard as a recommended compliance standard for all applicable
vessels that connect to an HVSC.
SOLAS Consolidated Edition 2014, Consolidated Text of the
International Convention for the Safety of Life at Sea, 1974, and its

with a reference to the more recent 2017 edition in all the
aforementioned sections where the NFPA 70 code is referenced except for
Sec. 111.105-7, which we are merging into Sec. 111.105-3. We also
include Sec. 110.15-1 in the list of sections referencing NFPA 70
because NFPA 70 is currently used in the definition of ``Special
Division 1.'' Substantive changes to the NFPA 70 articles from the
previous editions include the following:
[cir] Article 240--This article on overcurrent protection raised
the threshold for high voltage overcurrent protection from 600 V to
1000 V. Additionally, it addresses arc energy reduction of fuses rated
at 1200A or higher.
[cir] Article 250.119--Section 250.119 details the identification
requirements for equipment grounding conductors. The 2017 and 2002
editions are similar, but the 2017 edition contains greater specificity
for specific installations and prohibits other cables to be covered in
manner that could confuse them with equipment grounding conductors.
[cir] Article 250.122--Section 250.122 details requirements for the
size of equipment grounding conductors. The content in the two editions
is similar, but the 2017 edition adds requirements for multi-conductor

threshold for high voltage busways was raised from 600 V to 1000 V.
Additionally, it provides more detailed wiring requirements.
[cir] Article 400--This article on flexible cords and cable
provides several additional types of flexible cords as well as
conductor sizes, but the allowable ampacities for the existing types of
flexible cords and cables have not changed. Additionally, it requires
that the maximum operating temperature be added to the required
markings.
[cir] Article 404--The applicability of this article on switches
has been raised from 600 V systems to 1000 V systems, and several
additional switch types have been added.
[cir] Article 430--This article on motors now raises the threshold
for motors requiring additional protective measures from 600 V to 1000
V. Part X has been added to provide greater detail on adjustable-speed
drive systems. Additionally, a variety of minor technical updates have
been adopted, including adding references to the latest standards.
[cir] Article 450--This article on transformers raised the
transformer threshold for high voltage transformers from 600 V to 1000
V. Additionally, minor editorial changes were made. For example, in
several sections the word ``sufficient'' was replaced with ``not less
than'' to ensure the intent was clear.
[cir] Article 504--Sections 504.10, 504.30, 504.50 and 504.60 on
intrinsically safe system design will be added in Sec. 111.105-11
because ISA RP 12.6 has been withdrawn by ISA. The requirements are
similar, and NFPA is the authoritative standard for electrical
engineering design.
NFPA 77--Recommended Practice on Static Electricity, 2019
Edition. This recommended practice applies to the identification,
assessment, and control of static electricity for purposes of
preventing fires and explosions. We currently reference the 2000
edition of this standard in Sec. 111.105-27(b). By means of this rule,
we reference instead the more recent 2019 edition, which has been
completely reorganized with only minor changes to the technical
content. However, the 2019 edition contains changes regarding the
characterization of low, medium, and high resistivity powders to
reflect generally accepted international standards.
NFPA 99--Health Care Facilities Code, 2018. This code
provides information on health care facilities related to medical gas
and vacuum systems, electrical systems, electrical equipment, and gas
equipment. We currently reference the 2005 edition of this standard in
Sec. 111.105-37. By means of this rule, we instead reference the more
recent 2018 edition. The 2018 standard contains extensive updates and
is the authoritative reference for flammable anesthetics.
NFPA 496--Standard for Purged and Pressurized Enclosures
for Electrical Equipment, 2017 Edition. This standard applies to
purging and pressurizing for electrical equipment in hazardous
locations, electrical equipment containing sources of flammable vapors,
control rooms or buildings in hazardous locations, and analyzer rooms
containing sources of flammable vapors or gases and located
[[Page 16333]]
in hazardous locations. NFPA 496 has been an industry standard for
purged and pressurized enclosures since 1971. We currently reference
the 2003 edition of this standard in Sec. 111.105-7, the 2008 edition
is currently referenced in Sec. 111.106-3(c), and the 2013 edition is
currently referenced in Sec. 111.108-3(d). By means of this rule, we
update the references to the more recent 2017 edition in Sec. Sec.
111.105-3 (formerly Sec. 111.105-7), 111.106-3(c), and 111.108-3(d).
This more recent edition of NFPA 496 was revised to ensure correlation
with NFPA 70. The definitions of ``energized'' and ``identified'' are
extracted from NFPA 70, clarify the requirements for equipment in
hazardous areas, clarify the definitions of Type X, Type Y, and Type Z
pressurization, and remove unspecific language such as ``near,''
``close to,'' and ``significant portion.'' Such terms cannot be
quantified in the design or evaluation of an installation designed to
the standard.
Naval Sea Systems Command (NAVSEA) DDS 300-2--A.C. Fault
Current Calculations, 1988. By means of this rule, we will remove this
standard from subchapter J because it is no longer supported or
available. This is one of four options for fault calculations in Sec.
111.52-5. We reorganize the requirements for short-circuit calculations
for systems 1500 kW or above in Sec. 111.52-5 into new Sec. 111.51-4.
The other three options that are currently in Sec. 111.51-4 are still
included in the new Sec. 111.51-4.
MIL-HDBK-299(SH), 1991--Military Handbook Cable Comparison
Handbook Data Pertaining to Electric Shipboard Cable Notice 1-1991.
This document provides basic information on, and listings of, shipboard
cables and also provides guidance for their design, handling,
installation, and maintenance. This current edition is referenced in
Sec. 111.60-3 regarding cable applications. By means of this rule, we
delete this standard because we are also rescinding Sec. 111.60-3,
which we discuss in section VI.C of this preamble, because we have
found that it is unnecessarily prescriptive.
UL 44--Standard for Safety Thermoset-Insulated Wire and
Cable, 2018. This standard specifies the requirements for single-

(classified) locations. We currently reference the ninth edition (2007)
of this standard in Sec. Sec. 111.106-3(b) and 111.108-3(b). By means
of this rule, we reference the ninth edition (2007) in Sec. 111.105-
3(b) as well. This ensures that standards are consistent for electrical
installations on all vessel and facility types.
UL 844--Standard for Safety: Luminaires for Use in
Hazardous (Classified) Locations, 2012. This standard provides
requirements for fixed and portable luminaires for installation and use
in hazardous (classified) locations. We currently reference the twelfth
edition (2006) of this standard in Sec. 111.106-3(b) and the
thirteenth edition (2012) in Sec. 111.108-3(b). By means of this rule,
we reference the more recent thirteenth edition (2012) in Sec.
111.106-3(b), and add a reference to this edition in Sec. 111.105-
3(b). This latest edition includes the following minor technical

UL 1042--Standard for Safety Electric Baseboard Heating
Equipment, revised September 9, 2014. This standard provides
requirements for portable and fixed electric baseboard heating
equipment rated at 600 V or less. We currently reference the third
edition (1994) of this standard in Sec. 111.87-3. By means of this
rule, we reference the more recent fifth edition (2014). This latest
edition includes the following technical revisions:
[cir] Revisions requiring portable heater power supply cords to
meet UL 817;
[cir] Revisions requiring electric connections to meet established
UL standards, UL 310, UL 486A-486B, UL 886C, UL 486E, or UL 1977;
[cir] Revisions to equipment grounding provisions; and
[cir] Update to the leakage current test.
UL 1072--Standard for Safety Medium-Voltage Power Cables,
revised June 19, 2013. This standard provides requirements for shielded
and non-shielded medium-voltage power cables. We currently reference
the third edition (2001) of this standard in Sec. 111.60-1(a). By
means of this rule, we reference the more recent fourth edition (2013).
The fourth edition contains revised supplemental jacket thicknesses.
Because supplemental jackets are only required for cables intended to
be buried in the ground, this revision has no substantive impact on UL
1072 cables intended for use on vessels.
UL 1104--Standard for Safety for Marine Navigation Lights,
Second Edition, 1998. This standard provides construction and testing
requirements for navigation lights. This standard is referenced in
Sec. 111.75-17(d). By means of this rule, we will align the naming
convention in the regulatory text with that of other UL standards and
specifically cite paragraph (d) in Sec. 110-10-1(q).
UL 1203--Standard for Safety: Explosion-Proof and Dust-
Ignition-Proof Electrical Equipment for Use in Hazardous (Classified)
Locations, revised April 24, 2015. This standard covers explosion-proof
and dust-ignition-proof electrical equipment for installation and use
in hazardous locations. We currently reference the third edition (2000)
of this standard in Sec. 111.105-9 and the fourth edition (2006) in
Sec. Sec. 111.106-3(b) and 111.108-3(b). By means of this rule, we
reference the more recent fifth edition (2015) in Sec. 111.105-3(b)
instead of Sec. 111.105-9 due to editorial reformatting of subpart
111.105, as well as Sec. Sec. 111.106-3(b) and 111.108-3(b). The more
recent edition has relatively minor technical clarifications with
minimal substantive changes.
UL 1309--Standard for Safety Marine Shipboard Cables,
2017. This standard provides requirements for distribution (power),
control, and signal cables for installation aboard marine vessels,
fixed and floating offshore petroleum facilities, and MODUs. We
currently reference the first edition (1995) of this standard in
Sec. Sec. 111.60-1, 111.60-3, and 111.106-5(a). By means of this rule,
we reference the more recent third edition (2017) only in Sec. Sec.
111.60-1 and 111.106-5(a) because we delete Sec. 111.60-3. The
standard has received updates to its construction, performance,
ratings, and markings requirements.
UL 1581--Standard for Safety Reference Standard for
Electrical Wires, Cables, and Flexible Cords, 2001. By means of this
rule, we delete references to this standard in Sec. Sec. 111.30-19,
111.60-2, and 111.60-6 because the referenced test in this standard,
VW-1,
[[Page 16335]]
has been moved to UL 2556, which is added to these sections as
discussed below.
UL 1598--Standard for Safety Luminaires, 2018. This
standard provides requirements for luminaires for use in nonhazardous
locations that are intended for installation on branch circuits of 600
V nominal or less. We currently reference the first edition (2000) of
this standard in Sec. 111.75-20. By means of this rule, we reference
the more recent fourth edition (2018), which has been extensively
updated based on changes in technology and construction techniques.
This edition includes added requirements for placement and construction
of LED luminaires as well as LED test methods. The standard also
includes LED components and subassemblies, and other LED requirements.
UL 1598A--Standard for Safety Supplemental Requirements
for Luminaires for Installation on Marine Vessels, First Edition (with
revisions through Apr. 17, 2015), Dec. 4, 2000. UL 1598, the First
Edition, December 4, 2000, is currently incorporated by reference in
Sec. 111.75-20. By means of this rule, we incorporate UL 1598A, the
First Edition with revisions through April 17, 2015 in that section. UL
1598A provides additional requirements for luminaires meeting UL 1598
and intended for vessels to ensure these luminaires are suitable for
marine and shipboard environments. The revisions to the First Edition
include non-substantive updates necessary due to changes in clauses of
standards referenced within UL 1598A that occurred since publication of
the First Edition.
UL 1604--Electrical Equipment for use in Class I and II,
Division 2 and Class III Hazardous (Classified) Locations, 1994. This
was one of many options in Sec. 111.108-3(b) for standards on
electrical equipment in hazardous locations. By means of this rule, we
delete this standard from Sec. 111.108-3(b) because UL withdrew this
standard and it is no longer active.
UL 2021--Standard for Safety Fixed and Location-Dedicated
Electric Room Heaters, 2015. By means of this rule, we reference this
standard in Sec. 111.87-3(a) for the first time. This standard
provides requirements for electric air heaters. It will be an
additional standard regulated entities may choose for electric air
heaters. The Coast Guard has previously accepted it on a case-by-case
basis as equivalent to the existing standards in Sec. 111.87-3(a).
UL 2225--Standard for Safety: Cables and Cable-Fittings
for use in Hazardous (Classified) Locations, 2013. This standard
contains construction and testing requirements for cables and cable-
fittings for use in hazardous locations. We currently reference the
second edition (2005) of this standard in Sec. 111.106-3(b) and the
third edition (2011) of this standard in Sec. 111.108-3(b). By means
of this rule, we reference the more recent fourth edition (2013) in
Sec. Sec. 111.105-3(b), 111.106-3(b), and 111.108-3(b). The latest
edition includes the addition of Type TC-ER-HL cable for use in Class
I, Zone 1 as permitted by the 2014 National Electrical Code to the
scope, editorial revisions, and error corrections. The incorporation of
this edition into all three sections ensures consistent, up-to-date
standards for electrical installations on all vessel and facility
types.
UL 2556--Wire and Cable Test Methods, 2015. This standard
describes the apparatus, test methods, and formulas to be used in
carrying out the tests and calculations required by wire and cable
standards. The flame retardant test VW-1, formerly of UL 1581, has been
moved to this standard and is now called FV-2/VW-1. By means of this
rule, we will replace UL 1581 with UL 2556 in Sec. Sec. 111.30-19(b),
111.60-2, and 111.60-6.
UL 60079-18--Standard for Safety Explosive Atmospheres--
Part 18: Equipment Protection by Encapsulation ``m'', Fourth Edition,
revised February 20, 2017. By means of this rule, we adopt this
standard as a replacement for ANSI/ISA 60079-18, which was withdrawn by
ISA. UL 60079-18 is not substantively different than ANSI/ISA 60079-18.
This standard gives the specific requirements for the construction,
testing and marking of electrical equipment, parts of electrical
equipment and Ex components with the type of protection encapsulation
``m'' intended for use in explosive gas atmospheres or explosive dust
atmospheres. We reference this standard in Sec. Sec. 111.105(e),
111.106-3(d), and 111.108-3(e).
B. Generator Prime Movers
By means of this rule, we will delete the requirements in
Sec. Sec. 111.12-1(b) and (c) for each generator prime mover to have
an independent overspeed device and to automatically shut down upon a
loss of lubricating oil pressure to the generator bearing. The Coast
Guard has required generator prime movers to meet ABS rules since 1965.
We incorporate the ABS Steel Vessel Rules for generator prime movers
without modification to reduce reliance on government-unique standards
where an existing voluntary standard will suffice, as advocated in OMB
Circular A-119. The ABS Steel Vessel Rules, which are already
incorporated by reference in Sec. 58.01-5,\6\ require these same
safeguards on all but small generator prime movers. The independent
overspeed device is required for each engine driving a generator of 220
kW (295 horsepower (hp)) and above, while the oil pressure shutdown is
required for generators of 100 kW (135 hp) and above. Because vessels
will have to comply with the ABS Steel Vessel Rules, there is no need
to duplicate these requirements in Sec. 111.12-1, and we find that the
requirements in the incorporation by reference sufficiently address the
concerns that Sec. 111.12-1(b) and (c) were intended to address.
---------------------------------------------------------------------------
\6\ We note that Sec. 58.01 currently incorporates by reference
the 2003 edition of the ABS Steel Vessel Rules. On October 18, 2021
we proposed in Updates to Marine Engineering Standards, 86 FR 57896
(Oct. 19, 2021) (proposed rule) to update the reference in Sec.
58.01 to the 2020 edition of the ABS Marine Vessel Rules.. This is
the same edition incorporated by reference in Sec. 110.10-1(a). If
we amend Sec. 58.01 through a final rule on this same topic, any
changes made would not conflict with the intent of Sec. 111.12-1.
Generator prime movers will have to meet the ABS Marine Vessel Rules
incorporated by reference in Sec. 58.01.
---------------------------------------------------------------------------
C. Electrical Cable
This rule updates and amends subpart 111.60 (Wiring Materials and
Methods) to align it more closely with the standards accepted
internationally by vessel classification societies and foreign
administrations.
This rule adds additional acceptable cable construction standards
to Sec. 111.60-1. In addition, due to the availability of widely
accepted additional standards, this rule removes many of the more
prescriptive cable requirements in Sec. Sec. 111.60-3 and 111.60-4.
We also are rescinding Sec. 111.60-3, which sets out the cable
application regulations, because we find that those regulations are
unnecessarily prescriptive. Instead, entities will consult the cable
construction standards in Sec. 111.60-1, as revised by this rule, for
the application of specific types of cable.
In Sec. 111.60-5(a), the Coast Guard currently requires that cable
installations meet the recommended practices contained in IEEE 45-2002,
and we excluded the section concerning cable splices. Now we will
update the edition to IEEE 45.8-2016 and remove the exclusion for the
section on cable splices because it is inconsistent with other
regulations to exclude them. Both the existing and revised regulations
regarding cable splices in Sec. 111.60-19 refer to IEEE 45's
recommendations for cable splices.
[[Page 16336]]
Additionally, in Table 111.60-7--Demand Loads, we make minor edits
so that ``bus-tie'' and ``feeder'' are plural where they appear in the
table. As previously mentioned in the IBR updates to Sec. 110.10-1, we
will also update the NFPA NEC 2002 standard to its newer edition, NFPA
70, where it appears in the table.
In the NPRM, we proposed to update the existing IEEE 45 reference
in Sec. 111.60-11(c) to section 5.7 of the 2016 version. A commenter
correctly noted this section does not address wire, so we removed
section 5.7 of IEEE 45.8 from the list of standards. The final rule
leaves the following updated standards to choose from: NPFC MIL-W-76D,
ANSI/UL 44, ANSI/UL 83, or an equivalent standard.
D. IEC 60092-502 Electrical Installations in Ships--Part 502: Tankers--
Special Features
This rule amends our regulations for hazardous locations contained
in Subpart 111.105 to allow the Coast Guard to accept IEC 60092-
502:1999 as an option for classification of hazardous locations (areas)
in the new Sec. 111.105-50. New section 111.105-50(a) contains an
alternative standard for the classification of hazardous locations
requirements in Sec. Sec. 111.105-29, 111.105-31, 111.105-32, 111.106-
9 and 111.106-11 of this subchapter. This section provides instructions
for how to use the IEC 60092-502:1999 option for the classification of
hazardous locations as well as specific requirements for ventilation
systems if system designers use IEC 60092-502:1999. This IEC standard
is referenced in SOLAS II-1/45.11, the International Code of the
Construction and Equipment of Ships Carrying Liquefied Gases in Bulk
section 10.1.1, the International Code for the Construction and
Equipment of Ships Carrying Dangerous Chemicals in Bulk section
10.1.2.1, and all major classification societies' rules. Allowing this
option will provide system designers with the flexibility to classify
and specify equipment for hazardous locations using the same scheme
used internationally.
IEC 60092-502:1999 is currently accepted for use by vessels in the
Coast Guard's ACP when supplemented with ``USCG Supplemental
Requirements for use of IEC 60092-502:1999 for application of SOLAS
regulation II-1/45.11 to U.S.-flag vessels.'' \7\ The Coast Guard
developed these supplemental requirements to ensure an equivalent level
of safety as the requirements of subpart 111.105. Through this rule,
the Coast Guard will accept IEC 60092-502:1999 without the supplement.
This edition of the standard has been published for over 15 years, and
we are not aware of any casualty history attributed to its use as
compared to vessels complying with the applicable U.S. regulations. For
these reasons, we will accept it as an option for U.S. vessels.

---------------------------------------------------------------------------
In Sec. 111.105-50(c), we specify that if IEC 60092-502:1999 is
used for hazardous locations classifications, then the applicable
ventilation requirements for cargo handling rooms on tank vessels in
subchapter D apply. This is not a new requirement, but it is placed
here to ensure system designers do not assume that compliance with the
ventilation standards in IEC 60092-502:1999 is sufficient. As noted in
the discussion of the comment section, this final rule also clarifies
that the mechanical ventilation must be capable of at least 30 air
changes per hour, based upon the gross volume of the space, for cargo
handling or pump rooms and other spaces where hazardous location
classification is dependent upon ventilation.
In the final rule, we also break down paragraph (c) into multiple
subparagraphs to help with readability. This change is an editorial
amendment that does not result in any substantive changes from what we
proposed in the NPRM.
E. Emergency Generator in Port
This rule amends our regulations for a vessel's emergency power
sources contained in subpart 112.05 to allow the emergency generator to
be used in port in the new Sec. 112.05-7. The current regulations in
Sec. 112.05-1 require that the emergency source of power must be
dependable, independent, and dedicated. The purpose of these
requirements in Sec. 112.05-1 is that emergency power must be
immediately and dependably available in the event of a loss of the
ship's service power. For decades this has been achieved by
installation of a dedicated and independent emergency generator.
In the late 1990s, IACS proposed a unified interpretation to the
IMO in light of improvements in automation and potential environmental
benefits. That proposal incorporated a set of additional safety
standards in order to allow the use of an emergency generator during
lay time in port. This interpretation, with the supplemental safety
standards, would encourage the use of a more appropriately sized
generator for lay time loads instead of an overly large ship service
generator while simultaneously assuring the availability of emergency
power. The IMO subsequently adopted this proposal in 2005, promulgated
it in IMO circular MSC/Circ.1176 (dated May 25, 2005), and updated it
in IMO circular MSC.1/Circ. 1464/Rev.1 (dated October 24, 2013). Since
then, most classification societies and flag states have harmonized
their rules to align with this interpretation.
Similar to the IMO, by means of this rule we will allow use of
emergency power systems that incorporate a generator with the
additional safeguards similar to those prescribed by the IMO. The
additional safeguards provide an equivalent level of safety as the
existing requirements in part 112 as well as other potential
operational benefits. With respect to providing a dependable source of
emergency power, operation of the emergency generator in port does not
decrease the dependability of the emergency power system. On the
contrary, regular operation of the generator with the associated
planned maintenance scheme required by MSC.1/Circ.1464/Rev.1 will
result in increased dependability and crew familiarity and an improved
readiness of the system should an emergency situation occur. Further,
the additional requirements related to load shedding, fuel and
lubrication oil systems, generator and switchboard construction, power
management, and operational instructions will ensure the dedicated and
independent operation of this system in an emergent situation and
solely provide service to the emergency power system. Overall, this
system will deliver additional flexibility to the crew while ensuring
the availability of a dedicated source of power in the event of an
emergency. The arrangements will result in improved performance, better
fuel economy, lower emissions, and higher reliability than less
integrated systems.
For these reasons, this rule will allow the emergency generator to
be used in port provided that supplemental safety standards are in
place. The supplemental safety standards incorporated in Sec. 112.05-7
are similar to those prescribed in MSC.1/Circ.1464/Rev.1 as well as
section 4-8-2/5.17 of the ABS Marine Vessel Rules.

F. Description of Additional Changes Within Subchapter J \8\
---------------------------------------------------------------------------
\8\ In addition to the changes specifically discussed in this
preamble, we note that we have made additional non-substantive edits
for clarity following the NPRM. For example, we removed the word
``both'' in Sec. 111.87-3 because, following the addition of a new
standard as discussed elsewhere in this rule, ``both'' was no longer
an accurate description.
---------------------------------------------------------------------------
Sec. 110.15-1 Definitions
This rule adopts a more descriptive definition of ``deadship'' that
aligns with 4-1-1/1.9.6 of the ABS Marine Vessel Rules and IEC 60092-
201:2019.
The definition of a ship's service loads and drilling loads are
moved from Sec. 111.10-1(a) to Sec. 110.15-1 so that all definitions
for subpart J are in one location.
Sec. 110.25-1 Plans and Information Required for New Construction
We have consolidated the hazardous locations plan submittal
requirements of the existing Sec. 110.25-1(i), (p), and (q) into a
single section, Sec. 110.25-1(i). The ``Offshore Supply Vessels of at
Least 6,000 GT ITC'' interim rule (79 FR 48893, Aug. 18, 2014) and the
``Electrical Equipment in Hazardous Locations'' final rule (80 FR
16980, Mar. 31, 2015) included plan submittal requirements, Sec. Sec.
110.25-1(p) and (q), respectively. As explained in Section V, we will
offer all types of vessels and facilities the same selection of
explosion protection standards. Therefore, the plan submittal
requirements are identical, and three separate sections are no longer
required.
This rule makes one addition to the list of required items to be on
the plan submission under existing Sec. 110.25-1(i). The plan must
clearly indicate the method of classification, Division or Zone, of the
hazardous location. This information is important to ensure appropriate
selection of equipment for the hazardous location.
Sec. 111.05-3 Design, Construction, and Installation; General
In Sec. 111.05-3(c), we clarify the grounding requirements for
appliances and tools so that the requirements are consistent with
current industry practice.
Sec. 111.10-9 Ship's Service Supply Transformers; Two Required
This rule revises the note to Sec. 111.10-9 to clarify that
transformers located downstream of the ship's service switchboard are
not required to be provided in duplicate. This item is regularly
misunderstood. This revision is consistent with the explanation on page
16 of NVIC 2-89, ``Guide for Electrical Installations on Merchant
Vessels and Mobile Offshore Drilling Units,'' dated August 14, 1989.\9\
---------------------------------------------------------------------------
\9\ NVIC 2-89, ``Guide for Electrical Installations on Merchant
Vessels and Mobile Offshore Drilling Units,'' is available at
https://www.dco.uscg.mil/Portals/9/DCO%20Documents/5p/5ps/NVIC/1989/n2-89.pdf.
---------------------------------------------------------------------------
Sec. 111.12-11 Generator Protection
In this section and many other sections, we replace the term
``semiconductor rectifier (SCR)'' with ``semiconductor converter,''
which is a term now more commonly used in industry.
Sec. 111.12-13 Propulsion Generator Protection
We are deleting this section on propulsion generator protection
because it is simply a reference to Sec. 111.35-1. This cross-
reference is not necessary.
Sec. 111.15-10 Ventilation
In Sec. 111.15-10(b)(2)(i), we add the IEC equivalent
classification of Class I, Division 1, Group B as an alternate
standard.
Sec. 111.25-5 Marking
Under Sec. 111.25-1, motors are required to meet the requirements
for generators in Sec. 111.12-5. That section in turn incorporates by
reference section 4-8-3 of the ABS Marine Vessel Rules, which means
that motors must meet that standard. Because the ABS Marine Vessel
Rules sufficiently address requirements for motor marking, we are
deleting this section on motor markings as unnecessary.
Sec. 111.30 Switchboards
The requirements for switchboards contained in IEEE 45 2002 are
replaced with requirements from the recently published IEEE 45.7
(2012), excluding section 6.3.3 related to steering gear circuit
overcurrent protection. We did not intend the NPRM to propose a change
the existing requirements for steering gear circuit overcurrent
protection. For this reason, in Sec. 111.30-5(a)(1) of this final
rule, we are incorporating section 6 of IEEE 45.7-2012, excluding
section 6.3.3 as discussed above in response to comments received on
the NPRM.
In the NPRM, we had proposed a new paragraph (c) that warned
readers that the interchangeability and compatibility of components
complying with both IEEE and IEC cannot be assumed. That effort was to
address the growing use of components meeting IEC standards on U.S.
vessels. As noted in the discussion of the comments related to Sec.
111.30-5, we have opted to remove paragraph (c) from the final rule
because complying with and enforcing this relatively vague requirement
would be difficult. Switchboards should be constructed in accordance
with the standards incorporated by reference in subpart 111.30.
The flame retardant test standard IEC 332-1 has been superseded by
IEC 60332-1-1:2015 and IEC 60332-1-2:2015. We are updating the
standards for the flame retardant test in Sec. 111.30-19(b)(4)
regarding buses and wiring accordingly.
This rule replaces the term ``pilot light'' with the more commonly
used term ``indicator light.''
Subpart 111.33 Power Semiconductor Rectifier Systems
We are replacing the requirements for semiconductor converters
contained in IEEE 45 2002 with requirements from the recently published
IEEE 45.2 (2012).
Sec. 111.50-3 Protection of Conductors
In Sec. 111.50-3(b)(2), we revise the requirement for steering
gear circuits from subchapter F to a more specific cite of Sec. 58.25.
We also remove the reference to IEC 92-202 from Sec. 111.50-3(c). This
standard does not address standard ratings for fuses or circuit
breakers.
Subpart 111.51 Calculation of Short-Circuit Currents and Subpart 111.52
Coordination of Overcurrent Protective Devices
This rule combines subparts 111.51 and 111.52 into new subpart
111.51 to more clearly and concisely present the requirements for
coordination of overcurrent protection devices and calculation of
short-circuit currents. The general discussion contained in current
Sec. 111.51-1 is based on IEC 60092-202:2016.
The short-circuit calculations requirements of new Sec. 111.51-
2(a) are from the existing Sec. 111.52-1. The new Sec. 111.51-2(b)
clarifies that the calculations must be performed to select suitably
rated equipment and protective devices. The short-circuit calculations
requirements of the new Sec. Sec. 111.51-3 and 111.51-5 are from the
existing Sec. Sec. 111.52-3 and 111.52-5, respectively.
We are deleting NAVSEA DDS 300-2 from the existing Sec. 111.52-
5(b) because it is no longer available. Instead, we add IEC 61660-
1:1997 as a standard for DC systems.
The requirements for the protection of vital equipment, Sec.
111.51-6, are from the existing Sec. 111.51-3.
[[Page 16338]]
Sec. 111.54-1 Circuit Breakers
In Sec. 111.54-1(c)(2), the maximum voltage for direct-current
circuit breakers meeting IEC 60947-2:2013 will be identified as 1500 V.
This is in accordance with that standard.
Sec. 111.75-17 Navigation Lights
In Sec. 111.75-17(a), this rule removes the requirement that a
feeder directly from the emergency switchboard supply the navigation
light indicator panel. The emergency switchboard must still supply the
panel, but this change allows for the common practice of supplying the
navigation lights from an emergency lighting panel rather being
directly fed from the switchboard. This is consistent with industry
practice and vessel classification society rules. As part of this
change we also delete Sec. 112.43-13, which provided details on the
navigation light panel feeder.
In Sec. 111.75-17(d)(2), we will offer EN 14744 as an alternative
for certification of navigation lights. UL 1104, which is currently the
only certification specifically referenced in Sec. 111.75-17(d)(2), is
the other acceptable standard, but it has not been updated in over 20
years and addresses neither LED light sources nor EMC testing. EN 14744
addresses LED lights and EMC testing and has been published for 15
years. The other construction and testing requirements of EN 14744 are
not identical to UL 1104, but it is accepted worldwide. We are unaware
of any safety concerns related to it. For these reasons, we feel it is
an acceptable option for certification of navigation lights. The Coast
Guard currently accepts navigation lights constructed and tested to the
requirements of EN 14744 on a case-by-case basis subject to the
additional requirements of the MSC`s Marine Technical Note 01-18,
Guidance for Establishing Equivalency to UL 1104 Navigation Lights.\10\
Following the publication of this final rule, we will accept EN 14744
without these additional requirements.
---------------------------------------------------------------------------
\10\ See https://www.dco.uscg.mil/Portals/9/MSC/MTN/MTN.01-18.07.16.18.LEDandEUNavigationLights.pdf.
---------------------------------------------------------------------------
Additionally in Sec. 111.75-17(d)(2), this rule clarifies the
requirements for battery powered navigation lights. The existing text
has been misinterpreted on occasion. Like all navigation lights, these
lights must be certified by an independent laboratory to the applicable
requirements of UL 1104, EN 14744, or an equivalent standard. This
ensures they meet the applicable requirements of the 1972 COLREGS and
the Inland Navigation Rules (33 CFR 83).
This rule deletes the requirement for a flashing light in the
existing Sec. 111.75-17(d)(4) because this requirement is contained in
section 22.11 of UL 1104 and section 4.4 of EN 14744.
Sec. 111.75-18 Signaling Lights
This rule deletes the outdated, prescriptive requirements on
signaling lights in this section that were based on the applicable
international requirements in 1996 and incorporates by reference ISO
25861. This standard provides performance requirements for daylight
signaling lamps pursuant to chapter V of SOLAS, 1974, as amended, and
chapter 8 of the International Code for Safety for High-Speed Craft.
Further, since 2002, navigation equipment required by chapter V of
SOLAS, including signaling lamps (or lights), have been required to be
type approved by the administration.
Sec. 111.75-20 Luminaires (Lighting Fixtures)
Throughout this section, we replace the term ``lighting fixture''
with the internationally used term ``luminaire,'' and we remove the
prescriptive requirements contained in this section. Lighting fixtures
meeting the standards incorporated by reference in this section, ANSI/
UL 1598A or IEC 60092-306:2009, are suitable for use on vessels.
Further, this rule specifies the clauses of ANSI/UL 1598A applicable to
nonemergency and inside-type decorative luminaires.
Sec. 111.83-7 High Voltage Shore Connection
This section contains a standard for HVSCs, IEC/IEEE 80005-1:2019,
applicable to ships that connect to shore power. The Coast Guard has
actively participated with state and local stakeholders, shoreside and
marine industry representatives, and equipment manufacturers to develop
a standard to safely connect to HVSCs. This standard is offered as an
option for compliance with state or local law, or when a vessel
voluntarily connects to an HVSC.
Sec. 111.99-3 Definitions
We remove this section of definitions because the definitions are
no longer necessary. Fire door holding and release systems are
discussed in greater detail in SOLAS II-2/9. Many years ago there were
detailed fire door system requirements in Sec. 111.99. Now Sec.
111.99-5 requires fire door holding and release systems, if fitted, to
meet SOLAS II-2/9.4.1.1.5.3. Previously, Sec. 111.99-5 required these
systems to meet SOLAS II-2/30.4.3, but we have updated this reference
to SOLAS II-2/9.4.1.1.5.3 based on the reorganization of SOLAS Chapter
II-2.
Subpart 111.103 Remote Stopping Systems
The order of the subsections in 46 CFR subpart 111.103 has caused
confusion and led readers to incorrectly infer that machinery space
ventilation is a separate category from the ventilation referred to by
46 CFR 111.103-7. We are making editorial changes to this section to
clarify its intent.
Subpart 111.105 Hazardous Locations
The Coast Guard completed two recent rulemaking projects related to
hazardous locations, the ``Offshore Supply Vessels of at Least 6,000 GT
ITC'' interim rule (79 FR 48893, Aug. 18, 2014) and the ``Electrical
Equipment in Hazardous Locations'' final rule (80 FR 16980, Mar. 31,
2015). We are revising subpart 111.105 (Hazardous Locations) to be
consistent with existing regulations. This final rule expands the list
of acceptable national and international explosion protection
standards, providing more options for operators. Additionally, in this
final rule, we combine important provisions from Sec. Sec. 111.105-3,
111.105-5, and 111.105-7 into one revised section, Sec. 111.105-3,
titled ``Approved Equipment.'' In the NPRM, we proposed to only combine
Sec. Sec. 111.105-3 and 111.105-5 into Sec. 111.105-3, but this
created confusion among commenters. We decided to also add Sec.
111.105-7 into Sec. 111.105-3 to consolidate all the approved
equipment regulations. The reason for this change is discussed
previously in response to comments related to Sec. 111.105-3.
We add the internationally accepted independent third-party
certification system, the International Electrotechnical Commission
System for Certification to Standards relating to Equipment for use in
Explosive Atmospheres (IECEx), as an accepted method of testing and
certifying electrical equipment intended for use in hazardous
locations. Existing Sec. 111.108-1(b) allows owners and operators of
existing U.S. MODUs, floating OCS facilities, vessels other than OSVs,
and U.S. tank vessels that carry flammable or combustible cargoes, the
option of using the same expanded list of standards and the IECEx
System. In amending subpart 111.105, we incorporate these standards so
that they are available to all vessels and facilities that must comply
with subchapter J.
In Sec. 111.105-11, we reduced the number of requirements listed
here for intrinsically safe systems because the standards for these
systems are now
[[Page 16339]]
contained in Sec. 111.105-3. Additionally, we are replacing ISA RP
12.6-1995 in the existing Sec. 111.105-11(d) with the standard that
supersedes it, ANSI/ISA 12.06.01-2003. This standard is now located in
Sec. 111.105-11(b).
In Sec. 111.105-7(a)(1)(i), we add ANSI/ISA 12.12.01 as a new
standard for equipment in hazardous locations. See section VI.A for
further explanation of this standard. In the NPRM, we also proposed
incorporating UL 783 and ANSI/UL 2062 into this section. In the final
rule, we have decided not to incorporate these standards by reference
because they would have added electrical equipment requirements that
were not already required for regulated vessels prior to this
rulemaking. We would like to evaluate these standards and their effect
on the industry more before considering them for incorporation by
reference.
In Sec. 111.105-17(b), we add IEC 61892-7:2019, IEC 60092-
502:1999, API RP 14, and API RP 14FZ as additional acceptable standards
for the use of conduit. See section VI.A for further explanation of
each standard.
In the new Sec. 111.105-28, we add ASTM F2876-10 to address
internal combustion engines in hazardous locations. Under the new
section, internal combustion engines installed in Class I Divisions 1
and 2 must meet the provisions of ASTM F2876-10. Like the expanded list
of standards for electrical equipment in hazardous locations, this
standard in subparts 111.106 and 111.108 is the result of previous
rulemaking projects and will be added to Sec. 111.105-28. This will
ensure a consistent standard for these installations on all vessel and
facility types.
In Sec. 111.105-31(e), we are providing the option for submerged
cargo pumps that do not meet Sec. 111.105-31(d) to receive concept
approval by the Commandant (CG-ENG) and plan approval by the Commanding
Officer, MSC. This is consistent with existing Sec. Sec. 111.106-3(f)
and 111.108-3(f).
In Sec. 111.105-31(f), we delete references to IEEE 45 1998 and
IEC 60092-502:1999 because they do not provide any additional
information on classification of cargo tanks beyond what is currently
in subchapter J.
In Sec. 111.105-31(o), we clarify the requirements for systems
installed in duct keels.
In Sec. Sec. 111.105-35 and 111.105-45, we update the IEC
classification notation in accordance with IEC 60079-10-2:2015.
In Sec. 111.105-41, we remove the reference to IEEE 45 1998
because the standard has been superseded.
Subpart 111.106 Hazardous Locations on OSVs
In Sec. 111.106-3(b)(1)(i), we incorporate ANSI/ISA 12.12.01 as a
new standard for equipment in hazardous locations. See section VI.A for
further explanation of this standard. In the NPRM, we also proposed
incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided
not to incorporate these standards because they would add electrical
equipment requirements that were not already required for regulated
vessels prior to this rulemaking. We would like to evaluate these
standards and their effect on the industry more before considering them
for incorporation by reference.
Sec. 111.107-1 Industrial Systems
In Sec. 111.107-1(b), we clarified the standards for switchgear.
Currently Sec. 111.107-1(b)(1) refers to an unnecessarily broad range
of standards. We simplify this section by cross-referencing the
specific sections of the existing regulations in subpart 111.30 that
apply to switchgears.
Subpart 111.108 Hazardous Locations Requirements on U.S. and Foreign
MODUs, Floating OCS Facilities, Vessels Conducting OCS Activities, and
U.S. Vessels That Carry Flammable and Combustible Cargo
We remove paragraph (b) from Sec. 111.108-1, which was a cross-
reference to the expanded list of standards and the IECEx System in
subpart 111.105; the paragraph is directed to owners and operators of
existing U.S. MODUs, floating OCS facilities, vessels other than OSVs,
and U.S. tank vessels that carry flammable or combustible cargoes. This
cross-reference to subpart 111.105 is no longer necessary because we
include the same standards and systems in Sec. 111.108-3 (General
requirements).
In Sec. 111.108-3(b)(1)(i), we add ANSI/ISA 12.12.01 as a new
standard for equipment in hazardous locations. See section VI.A for
further explanation of this standard. In the NPRM, we also proposed
incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided
not to incorporate these standards because they would add electrical
equipment requirements that were not already required for regulated
vessels prior to this rulemaking. We would like to evaluate these
standards and their effect on the industry more before considering them
for incorporation by reference.
Sec. 112.01-20 Final Emergency Power Source
We clarify the description of the final emergency power source in
this section. For the convenience of the reader, we also cross-
reference Sec. 112.15-5, which specifies the existing regulations for
final emergency power sources.
Sec. 112.05-5 Emergency Power Source
In Sec. 112.05-5(a), we clarify that the emergency power source
must be sized using a unity (1.0) service factor on all loads as
required by Table 112.05-5(a). This section currently states that the
emergency power source must simultaneously supply these loads. When
sizing the emergency power source to meet this requirement the loads in
Table 112.05-5(a) must have a service factor of unity, 1.0 or 100
percent. This is also referred to as a load factor. This is not a
change to the existing requirement but only a clarification of the
requirement that the emergency power source must be appropriately sized
to accomplish this task.
Sec. 112.15-1 Temporary Emergency Loads
In Sec. 112.15-1(s), we add the engineer's assistance-needed alarm
to the list of loads that must be powered by the temporary emergency
power source. This is consistent with the requirement in Sec. 113.27-
1(c) that states it must be powered from the same source as the general
alarm.
Sec. 112.43-13 Navigation Light Indicator Panel Supply
We delete the requirement that the emergency light indicator panel
be supplied directly from the emergency switchboard in this section. We
made this change because Sec. 111.75-1(a) will no longer require that
a feeder from the emergency generator directly supply the navigation
light indicator panel supply and instead allow it to be supplied by an
electrical panel, such as an emergency lighting panel, which is
supplied by the emergency switchboard.
Sec. 112.50-1 General
In Sec. 112.50-1(g), we delete the requirement that emergency
generators automatically shut down upon loss of lubricating oil
pressure. This section will continue to require that generators be set
to shut down automatically upon overspeed or operation of a fixed fire
extinguishing system in the emergency generator. Removing the
requirement for emergency generators to automatically shut down in case
of loss of lubricating oil pressure is consistent with classification
society rules and allows
[[Page 16340]]
the crew to decide in an emergency situation if the emergency generator
should be shut down. We also reformat Sec. 112.50-1(g) to clarify the
remaining regulations for emergency generator set shut downs.
In addition, we revise the format of paragraph (h) to clarify that
the alarms are required for all of the listed conditions in each
section, not just one of the two conditions listed in each section.
This is a non-substantive formatting edit that does not affect the
existing alarm regulations for emergency generators in Sec. 112.50-
1(h).
VI. Incorporation by Reference
Material that this rule incorporates by reference appears in Sec.
110.10-1, and is summarized and discussed in section V.A of this
preamble. Copies of the material are available either at the
publisher's web address included in the regulatory text of Sec.
110.10-1 or by contacting the publisher listed in the standard listed
in Sec. 110.10-1. We also reviewed and updated all the publisher's web
addresses listed in Sec. 110.10-1 to ensure they are current. The
following list of publishers offer some of the more recent standards we
propose to incorporate at no cost to the public: ABS, FM Approvals,
IMO, Lloyd's Register, NFPA, DDS/Military Handbook, and UL. Based on
the volume of equivalency requests the Coast Guard receives asking us
to confirm that the latest edition is equivalent to or better than the
edition currently incorporated, we believe industry already has access
to and uses these more recent standards. The affected industry
typically obtains the more recent editions of standards in the course
of their business, in order to address advancements in technology.
You may also contact the person in the FOR FURTHER INFORMATION
CONTACT section for additional direction on how to obtain access to
electronic copies of the materials. The Director of the Federal
Register approved the material in Sec. 110.10-1 for incorporation by
reference under 5 U.S.C. 552 and 1 CFR part 51.
VII. Regulatory Analyses
We developed this rule after considering numerous statutes and
Executive orders related to rulemaking. Below we summarize our analyses
based on these statutes or 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.
Details on the estimated cost savings of this rule can be found in
the rule's RA that follows. This rule has not been designated by OMB a
significant regulatory action under section 3(f) of Executive Order
12866. Accordingly, OMB has not reviewed it.
The Coast Guard received two public comments regarding the affected
population in the RA for the proposed rule. We discuss our responses to
these comments in section IV of the preamble of this final rule. We
incorporated the commenters' suggestions into the RA for this final
rule and revised the population of MODUs and Cargo and Miscellaneous
Vessels based on MISLE data. We also updated the total population for
the final rule (see table 4). In addition, we updated the mean hourly
wage rate using 2021 data from the Bureau of Labor Statistics (BLS). As
a result, we revised the estimated cost savings for this final rule.
Table 2 summarizes the changes from the NPRM to the final rule and
their expected impact on costs and cost savings. The changes we made to
the respective CFR sections from the NPRM to the final rule, which we
show in table 2, have no additional impact on the affected population
or the cost savings we estimated in this analysis.

------------------------------------------------------------------------
With this final rule, the Coast Guard will update subchapter J of
title 46 of the CFR to align the standards that govern electrical
equipment and installations on U.S.-flagged vessels with current
industry practices to ensure that the standards are consistent on all
vessel types referenced in subchapter J. The provisions of this final
rule will update existing standards through incorporation by reference,
provide options to use alternative standards, eliminate obsolete
standards, and clarify the existing requirements. The majority of the
updates will simply incorporate by reference more recent versions of
the same standards with little or no substantive change. The more
recent editions reflect more modern technologies, terminology, and
practices. By updating standards, we expect the final rule to generate
cost savings, from a reduction in equivalency requests, to industry and
the Federal Government of approximately $209,352 over a 5-year period
of analysis in 2021 dollars, using a 7-percent discount rate (we are
using a 5-year period of analysis because we anticipate this final rule
will not produce cost savings beyond this time period). We estimate
annualized cost savings to be approximately $51,059, using a 7-percent
discount rate. The cost savings are a result of industry submitting
fewer equivalency requests to the Coast Guard (and the Coast Guard,
therefore, needing to review fewer equivalency requests), and not from
the changes to the IBR standards we make with this final rule. We
expect the final rule to generate unquantified benefits because
incorporating these standards will simplify regulatory compliance,
reduce confusion, and provide industry flexibility. Table 3 provides a
summary of the impacts of the final rule.

------------------------------------------------------------------------
Affected Population
This final rule affects four parts in subchapter J of title 46 of
the CFR (110, 111, 112, and 113), as well as multiple subparts within
each part. Subchapter J applies to vessels covered by subchapters D, H,
I, I-A, K, L, O, R, and U of title 46 of the CFR.\11\
---------------------------------------------------------------------------
\11\ Title 46 CFR subchapter J lists two other subchapters, Q
and W. Subchapter Q does not contain vessels; it applies to vessels
in the other subchapters regarding equipment, construction, and
materials for specifications and approval. Similarly, subchapter W
does not contain vessels but applies to vessels that have lifesaving
appliances and arrangements in one of the subchapters previously
listed.
---------------------------------------------------------------------------
We updated the affected population for the final rule because two
years have elapsed since we collected the original data for the
proposed rule. This final rule will affect approximately 5,602 existing
inspected U.S.-flagged vessels. We obtained the affected population of
this rule from our MISLE database. For standards we are incorporating
by reference in this final rule, we expect all U.S.-flagged vessel
owners and operators to use the most recent incorporated standards,
some of which were updated as recently as 2020. For construction
standards, we expect all U.S.-flagged vessel owners and operators to
use the most recent incorporated standards that are in place at the
time of construction or modification of a vessel.
For the purpose of the cost savings analysis, we use a subset of
the total affected population because only owners and operators of new
U.S.-flagged vessels entering service annually will generate cost
savings by submitting fewer equivalency requests to the Coast
[[Page 16342]]
Guard. Included in the total population of 5,602 vessels are 1,460 new
U.S.-flagged vessels that entered service in the last 8 years, from
2014 to 2021. We divided 1,460 by 8 years to obtain an average of
approximately 183 new U.S.-flagged vessels annually (see table 4
below). We based the cost savings analysis on the past number of
equivalency requests owners and operators of new U.S.-flagged vessels
submitted to the Coast Guard over an 18-month period from September
2018 to February 2020. The Coast Guard received 10 equivalency requests
annually from owners and operators of new vessels during this period.
Prior to this time period, the Coast Guard did not collect data on
equivalency requests.
We expect this final rule will reduce the baseline number of
equivalency requests the Coast Guard receives from industry by 80
percent.\12\ We do not expect this final rule or any updates to
standards to eliminate the public's questions altogether; although this
rulemaking will update standards, we expect a certain number of
standards to be out of date each year because standards organizations
are continuously revising standards to reflect safety concerns or to
maintain pace with technological advancements within the industry.
Thus, we project that about 20 percent of the public still may have
questions about the standards they are using annually during the 5-year
period and expect the number of equivalency requests that we receive
from the public to be about 20 percent of its current annual level. The
Coast Guard makes a determination in the year we receive a question
(equivalency request) from the public; therefore, the questions will
not accumulate from one year to the next. For example, if we
characterize the number of questions in the first year as 100 percent
of the total amount, we expect this final rule to reduce the number of
questions by 80 percent in this year, which produces the cost savings.
The balance of 20 percent is the amount that remains, which comprises
the number of questions in the first year. In the second year, the
public generates additional questions based on the standards they are
using, which do not add to the number of questions in the first year.
Again, we treat the number of questions in the second year as 100
percent of the total amount, and we expect this final rule to reduce
the number of requests by 80 percent in this year, as we explained
above. This, again, leaves an amount of 20 percent, which comprises the
number of questions in the second year. Essentially, the number of
questions in a subsequent year replaces the number of questions the
Coast Guard resolves in the preceding year. This process continues
through to the fifth year of the analysis period when we expect
standards organizations to have completed the process of updating all
existing standards.
---------------------------------------------------------------------------
\12\ Generally, standards are updated every 5 years. We
therefore assume that 20 percent of the standards become outdated
each year as time elapses, so 100 percent/5 years = 20 percent
annually (outdated standards). So, the remaining 80 percent (100
percent-20 percent) will generate the cost savings.
---------------------------------------------------------------------------
Specifically, we expect owners and operators of new U.S.-flagged
vessels that enter service to submit two equivalency requests annually,
or a reduction of eight equivalency requests annually. Owners and
operators of new U.S.-flagged vessels submit equivalency requests to
the Coast Guard to ask for approval to use a standard that is not in
regulation but may be equivalently safe. We explain equivalency
requests in greater detail in the Cost Savings Analysis portion of this
RA.

This rule continues the Coast Guard's response to the Presidential
Regulatory Reform Initiative of Mar. 4, 1995, and directives including
Executive Orders 12866 and 13563 that are intended to improve
regulation and the regulatory process. The provisions of this final
rule will remove obsolete regulations, revise current regulatory text,
substitute performance-based options for regulatory compliance as
opposed to conventional prescriptive solutions, and incorporate by
reference more recent national and international industry standards
into the CFR. The Coast Guard recognizes the significant technological
advances in electrical engineering equipment, systems, and devices
carried on vessels. As a result, this final rule will encourage the use
of newer equipment and promote adherence to modern standards in the
industry. Industry also will realize cost savings from not having to
send equivalency requests to the Coast Guard. See table 4 for how parts
of the CFR will be affected by this final rule along with the
anticipated impacts.
Benefits of the Rule
Cost Savings Analysis
We divided all of the changes of this final rule into three
categories, which
[[Page 16343]]
we present in table 5: (1) Editorial changes to the CFR, (2) updates to
IBR standards with technical changes, and (3) IBR standards with
incorporated options or alternative options. The changes we make to the
standards incorporated by reference in this final rule will not result
in costs or cost savings to industry.
First, we will editorial changes to subchapter J that include such
items as the removal of outdated terminology and the consolidation of
text in different paragraphs into one paragraph, which includes
regulatory provisions in 46 CFR parts 110, 111, 112, 113; we expect
these changes to be a no cost change.
Second, we update IBR standards that have technical changes, which
includes regulatory provisions in numerous subparts of 46 CFR parts
110, 111, and 113. It is standard practice in vessel manufacturing to
follow the most recent editions of standards developed by
representative groups of experts using a consensus-based process,
because most manufacturers also supply materials to vessels not
required to comply with 46 CFR subchapter J. Manufacturers of certain
types of electrical equipment carried on vessels are currently
producing equipment to the more recent standards, most of which have
been published for at least several years and all of which have been
developed by standard-based development organizations. These more
recent standards, which this final rule adopts, provide greater clarity
and specificity than the outdated technical standards they are
replacing; therefore, we expect these changes to be a no cost change.
Third, for IBR standards that are one of several available
standards as referenced in subchapter J, we update standards with a
more recent edition (these will be alternative options) and add
standards as new options to the several other available standards for
vessel owners and operators and manufacturers of certain types of
electrical equipment. The combination of these options will provide
industry the opportunity to remove overly prescriptive requirements,
simplify regulatory compliance, and provide regulatory flexibility.
Many of the options, some of which are alternative options and others
of which are new, are IBR standards that affect multiple subparts of 46
CFR parts 110, 111, and 113. The remaining options are not IBR
standards and affect multiple subparts of 46 CFR parts 111 and 112. The
options we incorporate by reference apply to the same population of
5,602 vessels. We assume industry will use the more recent national and
international standards referenced in this rule. We expect adding a
revised or new standard, which represents a more recent standard
industry that is currently using, as an additional option to the
existing standards will be a no cost change because these standards are
not requirements; industry can instead choose a given standard to use
among different alternative options. See table 5.
Specifically, we adopt the following four changes to subchapter J,
related to generator prime movers, electrical cable construction,
hazardous locations, and emergency generators, in order to eliminate
outdated or unnecessarily prescriptive electrical engineering
regulations and add a limited number of alternative standards. Of the
four items listed in the following text, the generator prime mover
falls into the second category (IBR standards with technical changes),
while electrical cable construction, emergency generator, and hazardous
locations fall primarily into the third category (IBR standards with
proposed and alternative options), which we listed previously.
Generator Prime Mover
This final rule eliminates the regulatory requirements in Sec.
111.12-1(b) and (c) for each generator prime mover to have an
independent overspeed device and a loss of lubricating oil pressure to
the generator bearing shutdown. The ABS rules, already incorporated by
reference in Sec. 111.12-1(a) since 1965, require these same
safeguards on all but small generator prime movers. We also incorporate
by reference the ABS Steel Vessel Rules for generator prime movers
without modification. Industry has been using these rules for many
years and the removal of these requirements will not affect the
performance of the generator prime mover. We expect this to be a no
cost change.
Electrical Cable Construction
For electrical cable construction requirements in subpart 111.60,
this final rule incorporates by reference the more recent editions of
the 2017 IEC standards and 2017 editions of ANSI standards to ensure
alignment with current technological trends and to eliminate several
unnecessary prescriptive requirements. This final rule also aligns
electrical cable standards in subpart 111.60 with standards accepted
internationally by vessel classification societies and foreign
administrations and removes unnecessary, prescriptive requirements
developed by the Coast Guard, which in turn, will simplify compliance.
We expect this to be a no cost change because electrical cables are
readily available that meet the standards that we incorporate by
reference with this final rule.
Hazardous Locations
This final rule amends subpart 111.105 by incorporating by
reference the IEC standard 60092-502 as an alternative standard for
classification of hazardous locations. This IEC standard, published in
1999, is referenced in international standards and codes as well as all
major classification societies' rules. Because we are adding an
alternative standard and not changing requirements with this item, we
expect this to be a no cost or no cost savings change.
Emergency Generator
This final rule amends subpart 112.05 to allow vessel owners and
operators to use an emergency generator in port. Some U.S.-flagged
vessel owners and operators favor the availability of this option in
port because it is more fuel-efficient and results in fewer exhaust
emissions than using the ship's larger service generators. This option
is consistent with international guidance and classification society
rules. However, this option applies to a very small number of U.S.-
flagged vessel owners and operators who request it, and the Coast Guard
will approve the use of an emergency generator for vessel owners and
operators in compliance with subchapter J only. We expect this option
to have unquantified cost savings associated with it. We also
anticipate unquantified benefits due to a decrease in exhaust emissions
since an emergency generator uses less fuel than a ship's main
generator.
This final rule creates consistency between Coast Guard regulations
and national and international standards through incorporation by
reference, provides options with alternative standards, eliminates
obsolete standards, and clarifies the existing requirements through the
changes we adopt in 46 CFR subchapter J. We categorize these changes in
table 5, which summarizes the impacts of this final rule and the
affected parts and subparts in subchapter J. Consistent with DHS
practice, table 5 specifically lists all of the individual changes by
part, subpart, and paragraph of 46 CFR subchapter J. Table 1 in section
II of the preamble is a general summary of the changes in subchapter J.

----------------------------------------------------------------------------------------------------------------
Note: We may list the same citation of the CFR multiple times because we are proposing numerous changes to the
same paragraph. These changes may include clarifications, deletions, or insertions of text. The term ``current
industry standards'' means equipment manufacturers have been constructing equipment to the more recent
editions of standards.
The Coast Guard evaluated the affected population and estimates
that this final rule will generate cost savings for owners and
operators of new U.S.-flagged vessels who will no longer submit
equivalency requests to the MSC for review. This final rule will also
generate cost savings for the Federal Government, which will review
fewer equivalency requests. An equivalency request is when an owner or
operator of a new U.S.-flagged vessel sends questions to the Coast
Guard to ask for a review of the standards they are currently using.
Any member of the marine industry may submit a request, but it is
primarily submitted by vessel owners and operators. Generally, an owner
or operator makes such a request to seek a determination from the Coast
Guard on whether or not a standard not contained in Coast Guard
regulations is sufficient for use. For example, an equivalent standard
could be a more recent edition of a standard in subchapter J, or it
could be an alternative standard not currently listed in 46 CFR
subchapter J. A Coast Guard Marine Engineer compares the equivalent
standard with the standard incorporated by reference in subchapter J to
ensure it offers an equal or greater level of safety.
When evaluating the proposed alternative standard, we compare the
standard that industry is using to the standard in subchapter J that
addresses the type of engineering equipment under review. Typically,
owners and operators of existing U.S.-flagged vessels (at the time of
construction of a vessel and when a vessel enters service) use the more
recent standards in subchapter J, and, therefore they will not likely
request an equivalency review from the Coast Guard following this rule.
However, the Coast Guard expects owners and operators of new U.S.-
flagged vessels that enter service each year to nevertheless have some
equivalency questions because they may not be familiar with all of the
applicable regulations in subchapter J, which include the most recent
standards that are incorporated by reference.
Based on MSC data, the Coast Guard received 15 equivalency requests
over the period from September 2018 to February 2020; this is the only
period of time for which the Coast Guard maintained equivalency data.
This is equivalent to 10 requests annually (15 requests / 18 months x
12 months = 10 requests). We did not receive any public comments
concerning this estimate; therefore, we retain the estimate of about 10
requests annually for the final rule. MSC data, validated by CG-ENG,
show that a vessel owner or operator typically submits no more than one
equivalency request in a given year, no matter how many vessels they
may own or operate. Generally, organizations such as UL and the IEC
create electrical standards for industry that take into account updates
in the latest technology and construction techniques for electrical
equipment. These organizations usually review and update standards
every 5 years. Therefore, based on a 5-year interval, we generally
expect 20 percent of the standards to be out of date in a given year,
which, in turn, creates equivalency requests from industry. Because the
Coast Guard makes a determination on an equivalency request in the same
year it receives the request, we do not expect the number of
equivalency questions to accumulate from year to year such that the 20-
percent estimate will change in any year of a 5-year period. Even if we
publish a rule to address updates to electrical standards in subchapter
J, we still expect each year that the public will have questions about
the standards it is using, which generates equivalency requests on an
annual basis; we do not expect a published rule to eliminate the
public's questions altogether.
Industry Baseline Costs
Without this final rule or under the current baseline, the Coast
Guard receives approximately 10 equivalency requests annually, as we
discussed previously. To draft an equivalency request to the MSC, an
owner or operator of a U.S.-flagged vessel seeks the services of an
engineering design firm or a shipyard's technical staff for a Marine
Engineer or Naval Architect. Using the BLS ``Occupational and
Employment Statistics'' database and May 2021 wage estimates, the
unloaded mean hourly wage rate for Marine Engineers and Naval
Architects is $47.03 (occupational code 17-2121).\13\ To account for an
employee's non-wage benefits, we apply a load factor to the unloaded
mean hourly wage rate, which we calculated by using BLS's ``Employer
Cost for Employee Compensation''
[[Page 16346]]
database. We determined the load factor to be approximately 1.48,
rounded.\14\ We multiply $47.03 by 1.48 to obtain a loaded mean hourly
wage rate of approximately $69.60 for this occupation.
---------------------------------------------------------------------------
\13\ Visit https://www.bls.gov/oes/2021/may/oes172121.htm to
find 2021 unloaded mean hourly wage rate for occupations in the
United States.
\14\ A loaded hourly wage rate is what a company pays per hour
to employ a person, not the hourly wage an employee receives. The
loaded hourly wage rate includes the cost of non-wage benefits
(health insurance, vacation, etc.). To obtain the load factor, we
used the multi-screen data search feature from this database and
searched for ``private industry workers'' under ``total
compensation'' and then for ``all workers'' in the category
``Transportation and Materials Moving Occupations,'' within the
United States. We performed the same steps to obtain the value for
``wages and salaries.'' The series IDs for total compensation, and
wages and salaries are CMU2010000520000D and CMU2020000520000D,
respectively, which are not seasonally adjusted values. Using second
quarter data for 2021, we divided the value for total compensation,
$31.90, by wages and salaries, or $21.54, to obtain a load factor of
about 1.48, rounded. https://data.bls.gov/cgi-bin/dsrv?cm.
---------------------------------------------------------------------------
Based on information from the MSC and validated by subject matter
experts in CG-ENG, it takes a Marine Engineer or Naval Architect
approximately 40 hours of time to develop an equivalency request and
submit it to the Coast Guard for review, which includes the electronic
submission.
We estimate the total undiscounted cost for industry to submit 10
equivalency requests annually to be approximately $27,840, or $2,784
for each request (10 equivalency requests x $69.60 x 40 hours per
request). See table 6 for industry inputs.

Federal Government Baseline Costs
When the Coast Guard receives an equivalency request from a vessel
owner or operator (or an electrical equipment manufacturer), the Coast
Guard personnel at the MSC must review the request to provide a
determination on whether or not the proposed standard is equivalent to
a standard found in subchapter J. Based on information from the MSC and
validated by subject matter experts in CG-ENG, a civilian Coast Guard
Marine Engineer needs about 32 hours to review an equivalency request.
Based on 10 requests received annually, the Coast Guard expends
approximately 320 hours annually to review these requests. A Coast
Guard Marine Engineer typically has a Federal Government General
Schedule (GS) grade level of GS-14. The Office of Personnel Management
lists the hourly pay for Federal employees who work in the Washington,
DC area on its website, and records the hourly pay of a person with the
grade level of a GS-14, step 5 (the midpoint of the pay grade) as
$66.54.\15\ We then calculate the share of total compensation of
Federal employees to account for a Government employee's non-wage
benefits. The Congressional Budget Office reports total compensation to
Federal employees to be $64.80 per hour and wages to be $38.30.\16\ We
determine the load factor to be approximately 1.69 ($64.80 / $38.30).
We multiply $66.54 by 1.69 to obtain a loaded hourly wage rate of
approximately $112.45 for a GS-14 Senior Engineer (Marine Engineer or
Naval Architect). We estimate the total, undiscounted cost for the
Federal Government to review 10 equivalency requests annually to be
approximately $35,984 (10 equivalency requests x 32 hours for each
request x $112.45), or $3,598 for each request. See table 7 for the
Federal Government inputs.

We estimate the total, undiscounted baseline cost to industry and

annually. Table 8 presents a summary of the baseline costs associated

Industry Cost Savings
The baseline costs we estimate for industry is from vessel owners
and operators of new U.S.-flagged vessels that enter service each year
who submit equivalency requests. We expect this rule will reduce the
number of equivalency requests industry submits annually. We estimate
195 companies own the average number of 183 new U.S.-flagged vessels
that have entered service each year in the past 8 years. The number of
equivalency requests the Coast Guard has received annually from these
owners and operators is approximately 10 (a vessel owner or operator
will request an equivalency determination without regard to the number
of vessels owned). We anticipate standards organizations to update
their standards every 5 years. Therefore, we expect 20 percent of the
standards to be out of date in a given year over this period of time
(100 percent divided by 5 years equals 20 percent). We multiplied the
20 percent value by the baseline number of 10 equivalency requests the
Coast Guard receives annually from owners and operators of new U.S.-
flagged vessels. Therefore, we expect industry to submit 2 equivalency
requests (10 equivalency requests x 0.20) in any given year of the
analysis period, or a reduction in the number of requests of 80
percent. Similarly, the marine industry will save approximately 320
hours annually from not drafting and submitting equivalency requests
(320 hours = 8 requests x 40 hours for each request). The submission of
an equivalency request will not affect or change an existing
information collection request, nor will it create a new one, because
we estimate the number of requests to be approximately 2 annually,
which is below the threshold of 10 limit set by the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501-3520). The Federal Government does not
require the marine industry to submit these requests; vessel owners and
operators (or manufacturers) voluntarily submit requests only if they
have questions about the standards they are using.
[[Page 16347]]
Using the same labor category previously used to calculate the
baseline for industry costs, we estimate the total undiscounted cost
savings of this rule to industry to be approximately $22,272 annually
[(10 equivalency requests x 40 hours for each equivalency x $69.60 =
$27,840) minus (2 equivalency requests x 40 hours for each equivalency
request x $69.60 = $5,568)]. We estimate 5-year cost savings of this
rule to industry to be approximately $91,320, using a 7-percent
discount rate. We estimate the annualized cost savings to be
approximately $22,272, using a 7-percent discount rate, as shown in
table 9.

Federal Government Cost Savings
With this final rule, we expect the Coast Guard will review
annually 2 equivalency requests (10 equivalency requests x 0.20). This
again will be a reduction of 80 percent from the baseline number of 10
requests. With fewer equivalencies to review, the Coast Guard will also
save approximately 256 hours annually from not reviewing equivalency
requests (8 requests x 32 hours per request).
Using the same labor category previously for MSC personnel to
review an equivalency request, we estimate the total, undiscounted cost
savings of this final rule to the Federal Government to be
approximately $28,787 annually [(10 baseline equivalency requests x 32
hours for each equivalency request x $112.45 = $35,984) minus (2
equivalency requests x 32 hours for each equivalency request x $112.45
= $7,197)]. We estimate the 5-year discounted cost savings of this rule
to the Federal Government to be approximately $118,032, using a 7-
percent discount rate. We estimate the annualized cost savings to be
approximately $28,787, using a 7-percent discount rate, as shown in
table 10.

Total Cost Savings of This Rule
We estimate the 5-year, total discounted cost savings of this final
rule to be approximately $209,352 ($91,320 + $118,032), using a 7-
percent discount rate. We estimate the annualized cost savings of this
rule to be approximately $51,059, using a 7-percent discount rate. The
total annualized cost savings is the summation of the values in tables
9 and 10 ($22,272 + $28,787 = $51,059) as a result of the reduction in
the number of equivalency requests we expect annually from industry, as
shown in table 11.

Unquantified Cost Savings of the Final Rule
We expect this final rule will have unquantified cost savings
associated with the option of using an emergency generator while in
port. The use of an emergency generator in port will likely save fuel
because it does not require a vessel owner or operator to use a ship's
larger service generators. However, we are not able to quantify the
cost savings associated with this option because the Coast Guard does
not have the data to predict how many vessel owners and operators will
choose this option while in port. Nevertheless, we expect at least a
small number of vessel owners and operators to choose this option.
Additionally, we expect this final rule to generate qualitative
benefits. This final rule is necessary because it will update obsolete
standards, remove redundancy in regulatory text, clarify and rearrange
regulatory text, and provide options to owners and operators of vessels
and manufacturers of certain types of electrical equipment. By updating
standards and providing options, Coast Guard regulations will be less
ambiguous and conform to the more recent industry standards, thereby
ensuring consistency within the marine industry. Some of these options
we consider to be alternative options, and others will be new options.
With these changes, industry will follow less ambiguous regulatory
provisions, which we expect will create fewer equivalency requests. In
addition, we removed Coast Guard prescriptive requirements in some
places and replaced them with more recent national or international
standards, which should simplify compliance.
Regarding the use of an emergency generator while in port, this
option will likely reduce emissions and save fuel for vessel owners and
operators who choose to use an emergency generator while in port. Some
U.S.-flagged vessel owners and operators favor the availability of this
option in port because it is more fuel-efficient and results in fewer
exhaust emissions than using the larger ship's service generators. This
will be an option for a very small number of U.S.-flagged vessel owners
and operators who request it. This option is consistent with
international guidance and classification society rules. The Coast
Guard will approve the use of an emergency generator for vessel owners
and operators in compliance with subchapter J only.
We are not able to quantify the expected reduction in the exhaust
emissions because the Coast Guard is not able to predict how many
vessel owners and operators will choose this option while in port due
to the lack of data. The Coast Guard did not receive any public
comments on the proposed rule concerning cost or cost savings
associated with the use of an emergency generator and exhaust emissions
while a vessel is in port.
Analysis of Alternatives
(1) Industry would continue to meet the current standards in 46 CFR
subchapter J with no updates to standards or incorporations by
reference (current baseline without regulatory action).
This alternative is a representation of the current state of the
industry where vessel owners and operators would continue to follow
standards in 46 CFR subchapter J without any updates to standards. To
use a newer standard or alternative standard, industry must submit an
equivalency request, and the Coast Guard must grant that equivalency.
With this alternative, industry would not benefit from regulations
incorporating newer or alternative standards and would not benefit from
the latest advances in electrical equipment technology without
incurring the cost of submitting equivalency requests. With this
alternative, there would be no change in the costs.
With this alternative, we would not update the standards in 46 CFR
subchapter J, and industry would not follow the more recent standards,
which includes technological advancements in electrical equipment
carried on vessels. We rejected this alternative because it would not
create cost savings for the marine industry and industry also would not
benefit from this alternative because it would not provide needed
regulatory clarity.
(2) Issuance of a policy letter that would permit the marine
industry to meet the more recent editions of the IBR standards without
updating the editions that are incorporated by reference in 46 CFR
subchapter J.
For this alternative, we would issue a policy letter that would
permit industry members to meet the most recent editions of the
pertinent standards. With such a policy in place, we anticipate that
the marine industry would use the more recent editions of the IBR
standards. However, 46 CFR subchapter J would still contain outdated
standards and overly prescriptive regulations that we could only remove
through notice and comment rulemaking. Issuing a policy letter would
not provide the agency an opportunity for soliciting public comment on
current industry practice and standards. Additionally, the policy
letter would not be enforceable against the public, and the Coast Guard
could revise the policy letter without opportunity to comment.
We would expect the number of equivalency requests to decrease with
this alternative by the same amount as the preferred alternative, and
we also expect the cost savings associated with this alternative to be
the same as the preferred alternative. We estimate this alternative
would save industry approximately $22,272 annually (undiscounted). We
estimate the 5-year discounted cost savings of this alternative to
industry would be approximately $91,320, using a 7-percent discount
rate. We estimate the annualized cost savings would be approximately
$22,272, using a 7-percent discount rate. We rejected this alternative
because we would not be incorporating by reference the more recent
standards in the CFR, industry would not benefit from enhanced
regulatory clarity in subchapter J, and the public would not be given
the opportunity to comment on the appropriateness of the more recent
editions of the IBR standards.
(3) Preferred Alternative--Update the IBR standards in 46 CFR
subchapter J, create regulatory options, and make
[[Page 16349]]
editorial changes to reduce the ambiguity that currently exists.
With this alternative, we will update the current standards in 46
CFR subchapter J and incorporate the more recent industry standards.
This is the preferred alternative because it will create consistency
between Coast Guard regulations and national and international
standards, update the standards incorporated by reference to reflect
the more recent standards available, provide options for alternative
standards, eliminate obsolete standards, and clarify the existing
requirements.
This alternative will reduce the number of equivalency requests
from the marine industry and create cost savings for vessel owners and
operator and manufacturers of marine equipment. It will also reduce the
hours the marine industry will spend on drafting and submitting
equivalency requests to the Coast Guard. We analyzed and presented the
cost saving impacts of this alternative to industry and the Coast Guard
earlier in this RA.
B. Small Entities
Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 601-612)
(RFA), we have considered whether this final 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.
This rule creates cost savings for industry because we estimate
fewer equivalency requests will be submitted to the Coast Guard. We
expect equivalency requests to be submitted by owners or operators of
new U.S.-flagged vessels who may have questions about standards that
are not in 46 CFR subchapter J. Over an 8-year period from 2014-2021,
we found 1,460 new U.S.-flagged vessels entered service, or an average
of approximately 183 annually during this period. We found that 195
companies owned the 1,460 vessels.
Using the publicly-available online database ``ReferenceUSAgov''
(in addition to individual online searches of companies) to search for
company-specific information such as annual revenues and number of
employees, we found revenue or employee information on 119 of the 195
companies, or approximately 61 percent.\17\ Using the Small Business
Administration's ``Table of Size Standards'' and the North American
Industry Classification System codes listed in the table, we found 88
of the 119 companies to be small entities.\18\ We found the other 31
companies to be not small.\19\ We did not find information on the
remaining 76 companies; therefore, we assumed these companies to be
small entities for a total of 164 small entities out of 195 companies,
or approximately 84 percent.
---------------------------------------------------------------------------
\17\ http://www.referenceusagov.com.
\18\ The Coast Guard was unable to find revenue information for
two of these small entities.
\19\ https://www.sba.gov/document/support--table-size-standards.
---------------------------------------------------------------------------
We analyzed the potential economic impacts of this final rule on
small entities and found that each small entity that no longer submits
an equivalency request will save approximately $2,784 annually. We
estimate an 80 percent reduction in the number of equivalency requests
(from 10 to 2 annually) industry submits to the Coast Guard with this
rule; therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that
this final rule will not have a significant economic impact on a
substantial number of small entities.
Any small entity that does not submit an equivalency request will
not be impacted by any costs or cost savings.
C. Assistance for Small Entities
Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we offer to assist small
entities in understanding this rule so that they can better evaluate
its effects on them and participate in the rulemaking. 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
The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires
the U.S. Coast Guard to consider the impact of paperwork and other
information collection burdens imposed on the public. The Coast Guard
has determined that there will be no new requirement for the collection
of information associated with this final rule.
E. Federalism
A rule has implications for federalism under Executive Order 13132
(Federalism) if it has a substantial direct effect on 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 Executive Order 13132 and
have determined that it is consistent with the fundamental federalism
principles and preemption requirements described in Executive Order
13132. Our analysis follows.
It is well settled that States may not regulate in categories
reserved for regulation by the Coast Guard. It is also well settled
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 United States v. Locke, 529 U.S. 89, 115-116 (2000)
(holding that Congress intended that the Coast Guard regulations be the
sole source of vessel design, operation, and reporting requirements).
This proposed update to electrical engineering standards for vessels is
issued under the authority in 46 U.S.C. 3306(a)(1), which authorizes
the Secretary to prescribe regulations for the design, construction,
alteration, repair, and operation of vessels subject to inspection,
including equipment, appliances, propulsion machinery, auxiliary
machinery, boilers, unfired pressure vessels, piping, and electric
installations. Therefore, because the States may not regulate within
these categories, this rule is consistent with the fundamental
federalism principles and preemption requirements described in
Executive Order 13132.
F. Unfunded Mandates
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 Unfunded Mandates Reform 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. Although
this rule will not result in such expenditure, we discuss the effects
of this rule elsewhere in this preamble.
[[Page 16350]]
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 will not create an
environmental risk to health or risk to safety that might
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 will 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). We have determined that it is not a
``significant energy action'' under that order because it is not a
``significant regulatory action'' under Executive Order 12866 and is
not likely to have a significant adverse effect on the supply,
distribution, or use of energy.
L. Technical Standards and Incorporation by Reference
The National Technology Transfer and Advancement Act, codified as a
note to 15 U.S.C. 272, directs agencies to use voluntary consensus
standards in their regulatory activities unless the agency provides
Congress, through OMB, 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:
