Electrical Engineering Requirements for Merchant Vessels
AGENCY: Coast Guard, DOT.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: As part of the President's Regulatory Reinvention Initiative,
the Coast Guard proposes to amend its electrical engineering
regulations to reduce the regulatory burden on the marine industry,
purge obsolete and out-of-date regulations, and eliminate requirements
that create an unwarranted differential between domestic rules and
international standards. This proposed rulemaking would harmonize,
where possible, the electrical engineering regulations with recent
amendments to the International Convention for the Safety of Life at
Sea, 1974, as amended. Additionally, this proposed rulemaking would
dramatically revise certain prescriptive electrical equipment design,
specification, and approval requirements and replace them with
performance-based requirements that incorporate international standrds.
DATES: Comments must be received on or before March 18, 1996.
ADDRESSES: Comments may be mailed to the Executive Secretary, Marine
Safety Council (G-LRA/3406) (CGD 94-108), U.S. Coast Guard
Headquarters, 2100 Second Street SW., Washington, DC 20593-0001, or may
be delivered to room 3406 at the same address between 8 a.m. and 3
p.m., Monday through Friday, except Federal holidays. The telephone
number is (202) 267-1477. Comments on collection-of-information
requirements must be mailed also to the Office of Information and
Regulatory Affairs, Office of Management and Budget, 725 17th Street
NW., Washington, DC 20503, ATTN: Desk Officer, U.S. Coast Guard.
The Executive Secretary maintains the public docket for this
rulemaking. Comments will become part of this docket and will be
available for inspection or copying at room 3406, U.S. Coast Guard
Headquarters, between 8 a.m. and 3 p.m., Monday through Friday, except
Federal holidays.
A copy of the material listed in ``Incorporation by Reference'' of
this preamble is available for inspection at room 1300, U.S. Coast
Guard Headquarters.

Background and Purpose
On March 30, 1995, the Coast Guard published a notice of a public
meeting in the Federal Register (60 FR 16423) and solicited written
comments on the President's recently announced Regulatory Reinvention
Initiative as well as the Coast Guard's regulatory development process.
The meeting was held on April 20, 1995, with a written comment period
extended from May 1 to December 8, 1995.
On May 31, 1995, the Coast Guard published a notice in the Federal
Register (60 FR 28376) that stated that the Coast Guard has established
a goal of eliminating any regulatory differential between requirements
that apply to U.S. vessels in international trade and those that apply
to similar vessels in international trade that fly the flag of
responsible foreign nations. To the maximum extent possible,
requirements that create an unwarranted differential between U.S. and
internationally recognized standards will be eliminated. This revision
of the electrical engineering regulations is, in part, part of this
project.
The Coast Guard's electrical safety regulations are based on
statutory authority provided in 46 U.S. Code (U.S.C.) 3306 and 3703.
The existing regulations for inspected vessels are contained in chapter
I, subchapter J, of title 46 of the Code of Federal Regulations (46 CFR
chapter I, subchapter J). This proposal is mainly concerned with
changes to this subchapter but associated changes in subchapters I-A
and Q also are being proposed. All cites in this proposal, unless
otherwise indicated, are to title 46 CFR.
This project proposes to revise technical areas of subchapter J to
address comments received from Coast Guard field and inspection offices
and the marine industry; to clarify requirements where confusion has
been shown to exist; to delete or significantly modify obsolete
requirements; to reflect experiences with vessel reflaggings; and to
more closely parallel international standards. The revision also
proposes to incorporate the latest International Convention for the
Safety of Life at Sea, 1974 (SOLAS 74) amendments (up to and including
1992), elements of the Coast Guard Regulatory Reform (CGRR) initiative,
and industry standards.
The increased frequency of overseas construction of U.S. flag
vessels has created a need for the Coast Guard to recognize equipment
designed and installed in accordance with international standards. The
implementation of SOLAS 74 by the international maritime community has
promulgated requirements which closely parallel existing Coast Guard
regulations. Subchapter J will be revised to facilitate U.S. acceptance
of electrical equipment constructed in accordance with other
international standards.
To eliminate needless regulatory burden, the Coast Guard is
proposing to delete and extensively revise obsolete or confusing
regulations. For example, the entries for Engine Order Telegraphs are
proposed to be consolidated and updated. Additionally, the necessary
degree of safety and reliability for sound powered telephones can be
maintained with minor additions to subchapter J. This proposal would
encompass the changes which would make type approval by the Government
unnecessary. Therefore, in conjunction with these proposed changes, the
Coast Guard would remove the approval requirement for sound powered
telephone equipment (now in subchapter Q) and adopt minimum
[[Page 4133]]
performance requirements in subchapter J. Similar treatment is being
given Fire Protective Systems. A wide variety of national and
international standards covering different types of equipment are also
proposed for incorporation by reference. Also under the proposal, the
equipment manufacturer would be afforded a choice of Independent
Laboratories versus the old single-point of testing. Modification of
current requirements is allowed under existing U.S. statutes, as 46
U.S.C. 3306 and 3703 provide broad authority to the Secretary to
prescribe safety regulations. Presently in the regulations, a Fire
Protection Equipment manufacturer is required to provide a sample of
its system, built only to the rigid specifications in part 161, subpart
161.002, to the National Bureau of Standards for testing. The Coast
Guard would allow equipment to be constructed to several domestic and
an internationally recognized standards. Also, the Coast Guard
continues to process applications from a variety of third party testing
institutions and Commandant (G-MMS) maintains a list at Coast Guard
headquarters of Independent Laboratories recognized by the Commandant.
The use of large industrial systems independent of a traditional
ship's service and propulsion functions are becoming increasingly
popular. These types of systems provide power to systems that are vital
to a vessel's mission but not necessarily to its safety. Industrial
systems would include drilling, manufacturing and scientific research.
Due to the industrial nature of these systems, it is not necessary for
them to meet the requirements in subchapter J which are intended to
provide for reliable ship's service and electrical propulsion systems.
New requirements, therefore, are being proposed which would permit the
use of standard industrial equipment without requiring them to meet
many of the requirements of subchapter J. Electrical installations in
hazardous locations will continue to meet explosion-proof/
intrinsically-safe requirements. This action serves the needs of
industry while ensuring a comparable level of safety.
On November 1, 1974, the Assembly of the International Maritime
Organization (IMO) adopted the International Convention for the Safety
of Life at Sea, 1974 (SOLAS 74). To date, IMO has adopted seven sets of
amendments to the convention pursuant to Article VIII of SOLAS 74. The
United States has played an instrumental role in the development of the
Convention and its amendments. As a signatory nation to this
international treaty, the United States has embraced these amendments
and periodically upgrades existing regulations, as necessary, to bring
it into alignment with the SOLAS 74 requirements.
The Coast Guard's electrical engineering regulations were last
updated in 1982. In that rulemaking, the Coast Guard reorganized its
regulations and incorporated the first set of amendments to SOLAS 74.
This rulemaking proposes incorporating the second through seventh sets
of amendments to SOLAS 74 (those of 1983, 1988, 1989, 1990, 1991, and
1992.) In doing so, the Coast Guard inspected vessels' electrical
safety regulations would be aligned with the international standards
for safety which are accepted for merchant ships around the world.
Discussion of Proposed Rules
The proposed revisions to 46 CFR chapter I, subchapter J, would
clarify and condense, in technically correct language, the Electrical
Engineering Regulations applicable to U.S. Coast Guard certificated
vessels. The objective of these revisions is to further reduce the
regulatory burden on the industry, eliminate misinterpretation of the
regulations by all affected parties, and bring the regulations in line
with the state of the art technology in the industry as well as with
standards accepted by the international maritime community.
The major changes to subchapter J are discussed below. Other
changes which are editorial and do not affect the technical content of
this subchapter are not addressed. The editorial corrections are to
help the reader understand the intent of the requirements.
As part of the associated changes, the Coast Guard is also
proposing to revise 46 CFR 108.170, Definitions, and Sec. 108.181,
Ventilation for enclosed spaces, to refer to the appropriate sections
of subchapter J.
In addition to updating subchapter J to reflect the most recent
amendments to SOLAS 74, the Coast Guard is also proposing to revise
subchapter J to incorporate by reference numerous internationally
recognized marine electrical standards which address construction,
installation, testing, and safety.
Part 110--General Provisions
Section 110.01-1. The Coast Guard would revise Sec. 110.1-1,
General, to add 46 CFR chapter I, subchapter K, Small Passenger Vessels
Carrying more than 150 Passengers or with Overnight Accommodations for
more than 49 Passengers, subchapter L, Offshore Supply Vessels,
subchapter R, Nautical School Vessels, and subchapter W, Lifesaving
Appliances and Arrangements, to the list of subchapters which require
electrical installations in accordance with subchapter J. This is not
additional regulation; but an entry to correct a prior omission such as
with subchapter R since Sec. 167.40-1(a)(2) already requires such
compliance; and cross-reference to new subchapters.
Section 110.01-3. The Coast Guard would revise Sec. 110.01-3,
Repairs, to address alterations as well as repairs. It is proposed that
minor alterations on vessels meet the requirements of the regulations
in effect on the contract date for the original installation, or the
contract date for the alteration. Unlike minor repairs and alterations,
major conversions, such as adding a large section to the midbody of the
vessel or changing the type or size of the main propulsion engine are
considered, under Coast Guard policy, on a case-by-case basis by
Commandant (G-MCO). Having a single point of review for these
situations ensures consistency in application of statutes and
regulations.
Section 110.10-1. The Coast Guard would update Sec. 110.10-1,
Incorporation by reference, to reflect new standards and to update the
editions of references already incorporated. This section provides the
addresses of organizations which publish the referenced standards.
Additionally, the sections affected by the incorporation of standards
are identified in Sec. 110.10-1.
Section 110.15-1. The Coast Guard would revise Sec. 110.15-1,
Definitions, to reflect new and modified terms and definitions used in
the subchapter. These minor word changes would bring our regulation
terminology in line with internationally accepted language. The
proposed changes would remove the reference from ``lifeboats'' and
replace it with the SOLAS 74 term ``survival craft'' and would replace
the current definition for dead ship with the SOLAS 74 definition,
(i.e., remove reference from ``ship service generators'' and replace it
with ``auxiliaries''). The definition for ``flashpoint'' would be
revised to reflect the current industry definition. Definitions for
``waterproof'', ``watertight'', and ``dripproof'' would be modified
with reference to the text in the National Electrical Manufacturers
Association (NEMA) and the International Electrotechnical Commission
(IEC) enclosure categories for the proposed Sec. 111.01-9, Degree of
protection. Proper training and licensing would be added to the list of
criteria under the definition for qualified person. This is proposed in
order to
[[Page 4134]]
quantify the definition since Certificates of Inspection require a
vessel to be manned by personnel holding certain licensed and
unlicensed ratings. Parts 10 and 12 of 46 CFR detail the training,
experience and testing procedures needed to obtain these licenses and
documents. On the face of the merchant marine license it states that
the holder has been duly examined and found competent.
Section 110.20-1. The Coast Guard would revise Sec. 110.20-1,
Conditions under which equivalencies may be used, to allow the
Commanding Officer, Marine Safety Center (MSC) to accept equivalencies
for fittings, materials, apparatus, equipment, or arrangements required
by this subchapter. With the consolidation of the Coast Guard's three
former merchant marine technical offices into one central location, the
opportunity for different interpretations of equivalencies by different
Coast Guard offices no longer presents a problem. Allowing the Marine
Safety Center to accept equivalencies enables the submitter to send all
plans to one point of contact within the Coast Guard. This procedural
change would not alter the appeal procedures already contained in 46
CFR 1.03, Rights of appeal.
Subpart 110.25. The Coast Guard would revise various paragraphs of
subpart 110.25, Plan Submittal, to remove Commandant (G-MMS) as one of
the offices to which plans may be submitted. Commandant (G-MMS) does
not perform plan review for specific vessels. All vessel plan review is
now conducted by the U.S. Coast Guard Marine Safety Center (MSC). Also,
several terms in Sec. 110.25-1(c) will be changed to reflect the
wording found in SOLAS 74 and other international standards.
Section 110.30-7. The Coast Guard would revise Sec. 110.30-7,
Repairs or alterations, to clarify the material. This section
complements Sec. 110.01-3, Repairs, regarding minor and major repairs
and alterations. This has been the long-standing regulation in
subchapter D: 46 CFR 30.01-10, Application of regulations governing
alterations or repairs. Although the application of these regulations
has become standard practice for all types of vessels, the Coast Guard
now proposes to repeat it in the electrical engineering regulation
subchapter to remove any misunderstanding and clarify that this
requirement applies to electrical systems on all vessels subject to
subchapter J.
Subpart 110.35. The Coast Guard would add a new subpart 110.35,
Independent Laboratories, which would define Independent Laboratories.
An Independent Laboratory will be a laboratory which has been accepted
by the Commandant under part 159 of this chapter for the testing of
electrical and electronic equipment and other related apparatus.
Paragraph (j) of Sec. 110.25-1 would be changed to refer to an
Independent Laboratory instead of specifically named laboratories.
Part 111--Electric Systems--General Requirements
Section 111.01-5. The Coast Guard would add electrical cable to the
list of equipment in Sec. 111.01-5, Protection from bilge water. In
addition to being sound engineering practice, the American Bureau of
Shipping (ABS) Rules for Building and Classing Steel Vessels prohibit
generator cable installation in the bilge and the Institute of
Electrical and Electronic Engineers (IEEE) Standard 45 (Recommended
Practice for Electric Installations on Shipboard) recommend not
installing any cable in the bilge.
Section 111.01-7. The Coast Guard would revise Sec. 111.01-7,
Accessibility, to remove specific references, throughout the
subchapter, to detailed construction requirements. A new paragraph (b)
would be added which would provide general performance and safety
guidelines. These revisions would set standards for equipment based on
performance criteria and therefore allow the removal of more detailed
construction specifications.
Section 111.01-9. The Coast Guard would change the title of
Sec. 111.01-9, Watertight, waterproof, and dripproof equipment, to
Degrees of protection, and revise the section to reflect the revision
of Sec. 110.15-1, Definitions. These changes now bring the regulations
on enclosures in line with IEC standards while allowing the option of
National Electrical Manufacturers Association (NEMA) enclosure
selection.
Section 111.01-15. The Coast Guard would revise Sec. 111.01-15,
Temperature ratings, to require an ambient temperature of 45 deg.C for
most electrical equipment in machinery spaces instead of the currently
required 50 deg.C. The international community has established 45
deg.C as the standard ambient temperature for these shipboard
applications. Rotating machinery would still be required to be rated
for 50 deg.C because of its inherent heating characteristics, but
cable installed in machinery spaces would be rated at 45 deg.C.
Control and instrumentation equipment would be rated at 55 deg.C in
order to comply with the international requirements. The proposed
changes would still allow for derating equipment based on the actual
ambient temperature of the space.
Section 111.01-17. The Coast Guard would revise Sec. 111.01-17,
Nature of electric supply, by renaming the section, Voltage and
frequency variations, and deleting specific reference to restrictive
standard voltages and frequency as well as deleting table 111.01-17(b),
Standard Voltages. The revision would instead reference industry
standard operating parameters for electrical machines and apparatus.
Sections 111.01-19, 111.01-21, and 111.01-23. The Coast Guard would
add three new sections: Sec. 111.01-19, Inclination of the ship,
Sec. 111.01-21, Vibration, and Sec. 111.01-23, Humidity. These sections
would include requirements for the electrical systems in relation to
the inclination of a vessel and those for conditions of vibration and
humidity.
Section 111.05-1. The Coast Guard would revise Sec. 111.05-1,
Purpose, with a minor addition to include ``systems'' as stated in the
subpart title.
Section 111.05-07. The Coast Guard would revise Sec. 111.05-7,
Armored and metallic-sheathed cable, in order to align installation
requirements of armor sheathed cable with international standards.
Section 111.05-9. The Coast Guard would revise Sec. 111.05-9,
Masts, to address lightning protection for vessels with nonmetallic
masts. This proposed revision would account for the expanded use of
lighter weight composite materials for masts.
Section 111.05-19. The Coast Guard would revise Sec. 111.05-19,
Tank vessels; grounded distribution systems, to align the systems'
voltage limits with the IEC (1000 volts) vice 3000 volts currently
mandated in the regulations. This gives the designer of nominal 2400
volt plants the option of a grounded distribution system.
Section 111.05-23. The Coast Guard would revise Sec. 111.05-23,
Location of ground indicators, to include requirements for branch
circuit detection indicators where the circuit is isolated from the
main source by a transformer or other device. Normal ground detector
indication at the distribution switchboard is required in paragraph (a)
for conventional feeder circuits. This proposal extends indication
coverage to the load side of isolation devices whose circuits would not
be otherwise monitored. Also, this proposal brings to one central
location all ground detection device requirements and relieves the
engineer of the burden, especially in an emergency, of visiting each
transformer
[[Page 4135]]
or isolation device to ascertain the ground condition of the branch
circuit.
Sections 111.05-25, 111.05-27, and 111.05-29. The Coast Guard would
revise Sec. 111.05-25, Ungrounded systems, Sec. 111.05-27, Grounded
neutral alternating-current systems, and Sec. 111.05-29, Dual voltage
direct-current systems, to offer a greater number of options in ground
detection circuitry. The proposed revision would remove restrictive
wattage and current limitations on detection circuit components thereby
allowing for innovative design and would replace them with performance
parameters.
Section 111.05-33. The Coast Guard would revise Sec. 111.05-33,
Equipment grounding conductors, to require that each equipment
grounding conductor be insulated and be of a size at least equal to
current carrying conductor. This proposal would align our regulations
with the National Electrical Code (NEC).
Sections 111.05-37 and 111.05-39. The Coast Guard would consolidate
Sec. 111.05-39, Switches and circuit breakers, into Sec. 111.05-37,
Overcurrent device. Both sections presently address overcurrent
protection devices.
Section 111.10-1. The Coast Guard would revise paragraph (a) of
Sec. 111.10-1, Definitions, to remove certain cargo refrigeration
systems from the list of ship's service electrical loads. These loads
are industrial in nature and are not directly related to the safety of
the vessel. These refrigeration systems are added to the list of
industrial type loads in the same section.
Section 111.10-3. The Coast Guard would revise Sec. 111.10-3, Two
generating sets, to add the requirement that a Mobile Offshore Drilling
Unit (MODU) must have at least two ship's service generating sets. This
is presently a requirement of the International Maritime Organization
(IMO) MODU Code. The Coast Guard proposes the inclusion since
subchapter I-A for MODU Inspection and Certification references
subchapter J for their electrical systems.
Section 111.10-4. The Coast Guard would revise Sec. 111.10-4, Power
requirements; generating sets, to define the required generating
capacity. The changes would result in regulations which mirror the
requirements of SOLAS 74. The Coast Guard would revise paragraph (b) to
clarify the fact that the capacity of the ship's service generating set
or sets must be sufficient to carry the ship's service loads with the
largest ship's service generator stopped. The Coast Guard would revised
paragraph (d) to ensure that propulsion-plant loads do not impact on
ship's service loads when these loads are supplied by a common
generator. New paragraphs (e) and (f) would be added specifically to
address main-engine-dependent generators. The proposed regulation
reflects a harmonization with international standards, recognized
classification society requirements, and present industry practice for
these types of generators.
Section 111.10-7. The Coast Guard would revised paragraph (b) of
Sec. 111.10-7, Dead ship, by adding a sentence referencing additional
existing requirements contained in Sec. 112.05-3 of this chapter. These
requirements refer to the main and emergency bus-tie.
Sections 111.10-9 and 111.10-11. The Coast Guard would revise
Sec. 111.10-9, Ship's service supply transformers; 2 required, to
clarify the intent of the requirement and bring the requirements of
Sec. 111.10-11, Power requirements; transformers under this one
section.
Section 111.12-1. The Coast Guard would revised paragraph (a) of
Sec. 111.12-1, Prime movers, to incorporate American Bureau of Shipping
(ABS) Rules for prime movers, paragraph (b) to clarify that all
generator prime movers need a governor, and paragraph (c) to remove the
exemption from the automatic shut down in case of loss of lubricating
oil.
Section 111.12-5. The Coast Guard would revise paragraph (a) of
Sec. 111.12-5, Generator construction and testing, to reflect a change
in the ABS Rules numbering system and would remove the designation
``(a)'' from the paragraph. Paragraphs (b), (c), and (d) would be
removed.
Section 111.12-7. The Coast Guard would revise paragraph (a) of
Sec. 111.12-7, Voltage regulation and parallel operation, to reflect a
change in ABS Rules numbering system.
Sections 111.15-1, 111.15-2, and 111.15-3. The Coast Guard would
revise Sec. 111.15-1, General Sec. 111.15-2, Battery construction, and
Sec. 111.15-3, Battery categories, to eliminate restrictive
construction details and to allow the use of different types of
batteries, including sealed batteries and other designs. The specific
size requirement in paragraph (c) of Sec. 111.15-2 would be removed and
reclassification would be allowed under paragraph (d) of Sec. 111.15-3.
Additionally, the Coast Guard proposes a new paragraph (d) in
Sec. 111.15-2 be added as a performance measure to address a battery's
suitability for installation in the marine environment.
Section 111.15-5. The Coast Guard would revised paragraph (a) in
Sec. 111.15-5, Battery installations, by deleting the reference to
specific test laboratories. All electrical equipment and laboratory
testing requirements for hazardous locations would be addressed in
subpart 111.105, Hazardous Locations. Additionally, the Coast Guard
would allow for the expanded use of internationally available
electrical equipment by providing reference to IEC hazardous location
classifications. The Coast Guard would amend Sec. 111.15-5(c), Small
batteries, to allow liberal storage of small-size sealed batteries.
This is possible due to the reduced hazard associated with sealed
equipment. The Coast Guard would eliminate paragraph 111.15-5(e),
Tiers. This requirement is redundant with the spacing requirement
specified in paragraph 111.15-5(d), Battery trays. The remaining
paragraphs (f), (g) and (h) would be renamed (e), (f) and (g).
Section 111.15-10. The Coast Guard would revise paragraph (g) of
Sec. 111.15-10, Ventilation, to explain the intent of ventilation
requirements for small battery installations. If the battery box were
in a non-environmentally-controlled location, simple vent openings may
allow the ingress of water. A statement on preventing ingress would be
added.
Section 111.15-20. The Coast Guard would revise Sec. 111.15-20,
Conductors, to put the accepted installation practices presently
included in this section into proper terminology. The requirements in
paragraphs (b) and (c) would be combined into one paragraph.
Section 111.15-30. The Coast Guard would revise Sec. 111.15-30,
Battery chargers, to eliminate specific construction requirements for
battery chargers. In their place, the Coast Guard proposes certain
performance requirements.
Section 111.20-1. The Coast Guard would revise Sec. 111.20-1,
General requirements, to reflect internationally accepted practices for
transformer construction, installation and protection by allowing not
only the winding but also the enclosure to provide the necessary
protection.
Section 111.20-15. The Coast Guard would revise Sec. 111.20-15,
Transformer overcurrent protection, to reflect internationally accepted
practices for transformer overcurrent protection by allowing a choice
of standards.
Section 111.25-5. The Coast Guard would revise paragraph (a) of
Sec. 111.25-5, Marking, to allow nameplate markings in accordance with
the practices of the IEC as an alternative to the present National
Electrical Code requirement.
Section 111.30-1. The Coast Guard would revise Sec. 111.30-1,
Location and installation, to require switchboard installation to
follow industry practice by removing specific construction
[[Page 4136]]
detailed regulatory language and instead referring to the appropriate
guidance of IEEE Standard 45.
Section 111.30-4. The Coast Guard would revise Sec. 111.30-4,
Circuit breakers removable from front, to allow an alternative method
of circuit breaker installation. This would permit the circuit breaker
to be hard-wired to the switchboard if: (1) The switchboard is divided
into two or more sections that can be split by disconnecting a link
between a section of the switchboard, and (2) the connection of
generators and duplicated equipment is equalized between the sections
of the main bus. This allows for the capability of de-energizing a
section of the switchboard without shutting down the power supply or
degrading the continuity of power supply to vital loads.
Section 111.30-5. The Coast Guard would revise Sec. 111.30-5,
Construction, to remove detailed switchboard construction requirements
and incorporate international consensus standards (IEEE Standard 45 and
IEC Publications 92-302/92-503).
Sections 111.30-9, 111.30-11, and 111.30-13. The Coast Guard would
eliminate Sec. 111.30-9, Mechanical protection, Sec. 111.30-11, Mats or
gratings, and Sec. 111.30-13, Grounding. The requirements of these
sections are included in the industry practices of the IEEE Standard 45
and the IEC Publications.
Section 111.30.-19. The Coast Guard would revise Sec. 111.30-19
Buses and wiring. Paragraph (a) would be revised to allow for the
guidance of international performance standards instead of the present
detailed technical requirements. Paragraphs (b) through (e) would be
deleted because the information they contain is covered by proposed
paragraph (a). Paragraph (f) would be renamed paragraph (b) and would
be revised to allow for the use of small-conductor-size cable, such as
ribbon cable, for instrumentation and control circuitry, as is common
industry practice.
Section 111.30-21. The Coast Guard would eliminate Sec. 111.30-21,
High temperature devices. This design specification would be addressed
in the requirements of the appropriate industry standards of the IEEE
and IEC and need not be repeated here.
Section 111.30-23. The Coast Guard would eliminate Sec. 111.30-23,
Medium voltage switchboards. These requirements will be part of the
proposed revision of Sec. 111.30-5, Construction.
Section 111.30-24. The Coast Guard would revise Sec. 111.30-24,
Generation systems greater than 3000 kw, to modify the exemption for
MODUs to split the switchboard when the total generator power exceeds
3000 kw. The IMO MODU Code requires self-propelled MODUs to have a
split switchboard when the total installed generator capacity exceeds 3
Megawatts (3000 kw). Therefore the exemption will apply only to
nonself-propelled MODUs.
Section 111.30-29. The Coast Guard would revise Sec. 111.30-29,
Emergency switchboards, by adding paragraphs (g), (h) and (i). These
paragraphs are presently contained in part 112. The purpose of this
change is to consolidate all of the requirements for the emergency-
switchboard instrumentation and equipment into one section.
Section 111.30-31. The Coast Guard would delete Sec. 111.30-31,
Tests. Presently this section requires switchboards to be tested to an
American Bureau of Shipping requirements. American Bureau of Shipping
Rules do not address the testing of switchboards.
Section 111.33-3. The Coast Guard would replace the descriptive
nameplate requirements of Sec. 111.33-3, Nameplate data, for
semiconductor rectifier systems with industry practice according to
international standards.
Section 111.33-5. The Coast Guard would replace the descriptive
installation requirements of Sec. 111.33-5, Installation, for
semiconductor rectifier systems with industry practice according to
international standards.
Section 111.33-11. The Coast Guard would revise Sec. 111.33-11,
Propulsion systems, to reflect the current American Bureau of Shipping
numbering system regarding semiconductor rectifier systems.
Section 111.35-1. The Coast Guard would revise Sec. 111.35-1,
Electrical propulsion installations, to reflect the current American
Bureau of Shipping numbering system.
Section 111.40-1, 111.40-5, and 111.40-7. The Coast Guard would
remove Sec. 111.40-1, Panelboard, standard, to eliminate the
requirement of meeting a specific standard and thereby allowing the use
of panelboards which are designed and constructed according to sound
engineering practice. Likewise, the Coast Guard would revise
Sec. 111.40-5, Enclosure, and Sec. 111.40-7, Location, to allow the
installation of panelboards with a suitable degree of protection to be
installed in the weather. This change allows more latitude in the
electrical arrangement on the ship without reducing personnel safety
requirements.
Section 111.50-2. The Coast Guard would add a new Sec. 111.50-2,
Systems integration. This new section would reflect the need to
consider component compatibility within each overcurrent protection
system.
Section 111.50-3. The Coast Guard would revise paragraphs (c), (d),
(f) and (h)(2) of Sec. 111.50-3, Protection of conductors, to allow the
use and incorporate the requirements of the IEC for fuses, circuit
breakers, thermal devices and ground conductors.
Section 111.52-1. The Coast Guard would correct Sec. 111.52-1,
General, to identify the physical unit (i.e., ``current'') needed to be
calculated when performing short-circuit current calculations.
Section 111.52-5. The Coast Guard would revise Sec. 111.52-5,
Systems 1500 kilowatts or above, to allow several additional methods of
short-circuit current calculations. This would ensure that the
appropriate method of short-circuit current calculation is available to
the designer as well as the plan reviewer.
Section 111.53-1. The Coast Guard would revise paragraph (a)(1) of
Sec. 111.53-1, General, to eliminate specific reference to parts E and
F of the National Electrical Code relative to fuses. The revision would
add the option of meeting the general provisions of IEC internationally
recognized standards. Additionally, the Coast Guard would revise
paragraph (a)(3) to eliminate restrictive reference to Underwriters
Laboratories, Inc. This would expand industry's options to list fuses
with any Independent Laboratory. The Coast Guard would revise paragraph
(b) to eliminate prohibitive reference to Edison-base fuses. The Coast
Guard recognizes that systems designed and built to IEC and/or CEN
standards may contain these fuses. It is also recognized that many
Maritime Administration (MARAD) Ready Reserve Force reflagged vessels
have been operating with such equipment for years. The Coast Guard,
however, maintains its prohibition of renewable-link cartridge fuses
because it is considered a severe safety hazard in that a link of a
higher than recommended current value might be placed in a jacket
marked with a lower value and the fault be undetectable. The Coast
Guard would add a new paragraph (c) to provide for the ability to test
for fuse condition, particularly for installations utilizing Edison-
base fuses, since the glass or plastic link protector inhibits the
readily available test points offered by a more common cartridge fuse.
Section 111.54-1. The Coast Guard would revise Sec. 111.54-1,
Circuit breakers, to include reference to and the allowance of
internationally recognized standards and at the same time
[[Page 4137]]
eliminate reference to restrictive and specific construction standards.
Section 111.55-1, 111.55-5, 111.55-7, and 111.55-9. The Coast Guard
would delete Sec. 111.55-5, Knife switches, Sec. 111.55-7, Snap
switches, and Sec. 111.55-9, Enclosed switches. These requirements do
not provide an additional level of safety beyond that ensured by
compliance with Sec. 111.55-1, General.
Subpart 111.57. The Coast Guard would eliminate subpart 111.57,
Current-Limiting Devices. The operating and design characteristics of
current limiting devices would be included in the revision of subpart
111.53, Fuses, and subpart 111.54, Circuit Breakers. This, in turn,
reduces repetitive and unnecessary regulation.
Section 111.59-1. The Coast Guard would rewrite Sec. 111.59-1,
General, to eliminate paragraph (b) and the requirement that busways
meet a specific construction standard, as the performance of the
component is established by compliance with paragraph (a).
Section 111.59-3. The Coast Guard would revise Sec. 111.59-3, No
mechanical cooling, to correct an omission. In the present version, the
regulations state that ``A busway must need mechanical cooling * * *''
which is opposite to the intent of this section.
Section 111.60-1. The Coast Guard would revise Sec. 111.60-1, Cable
construction and testing, to align our regulation language with that of
the 1983 edition of IEEE Standard 45. Additionally, the Coast Guard
would propose to include, as acceptable, cable that is designed,
constructed, tested and installed in accordance with the international
standards of IEC Publications 92-3 and certain 92-350 series as well as
several MIL Specification cables.
Sections 111.60-2 and 111.60-6. The Coast Guard would add new
Sec. 111.60-2, Specialty cable for communication and RF applications,
and Sec. 111.60-6, Fiber optic cable, to include requirements for
specialty electrical cables and optical fiber cables. The proposed
requirements address installation and flammability characteristics for
these cables. The Coast Guard feels this is necessary because of the
present lack of guidance for this relatively new equipment now on board
or contemplated for installation on board certificated vessels and
because of the larger fire load the cable represents.
Section 111.60-3. The Coast Guard would revise Sec. 111.60-3, Cable
application, to include the applicable requirements of IEC Publication
352 and to assure proper derating of cables according to type
construction.
Section 111.60-4. The Coast Guard would revise Sec. 111.60-4,
Minimum cable conductor size, to include instrumentation cable with the
thermocouple and pyrometer group. Mention of general instrumentation
cable was unintentionally omitted from the regulations during the last
revision.
Section 111.60-5. The Coast Guard would revise Sec. 111.60-5, Cable
installation, to include reference to the installation of cables
constructed in accordance with the international standard IEC
Publication 92-3 and the IEC 92-350 series.
Section 111.60-11. The Coast Guard would revise Sec. 111.60-11,
Wire, to expand the choices available for shipboard wiring. The current
requirements are too restrictive and do not constitute an appreciable
increase in safety beyond the proposed reduction in those requirements.
Section 111.60-13. The Coast Guard would revise paragraph (a) of
Sec. 111.60-13, Flexible electric cord and cables, to remove the
restrictions presently governing the use of flexible cord and cables.
The proposed change allows compliance with a larger number of
nationally-recognized standards.
Section 111.60-17. The Coast Guard would revise Sec. 111.60-17,
Connections and terminations. The current regulations are merely a
narrative describing standard marine practice. The proposed revision
would outline specific installation criteria for connectors and
terminals.
Section 111.60-19. The Coast Guard would revise Sec. 111.60-19,
Cable splices, to reflect current industry practice as outlined in the
internationally accepted IEEE Standard 45.
Section 111.60-21. The Coast Guard would revise Sec. 111.60-21,
Cable insulation tests, to reflect a change in numbering system of the
referenced IEEE standard.
Section 111.60-23. The Coast Guard would add a new Sec. 111.60-23,
Type MC cable, to address the lack of requirements primarily on
offshore production platforms. However, the installation of this cable
is not limited to offshore platform applications and may be used as
shipboard cable provided certain installation requirements are
followed.
Subpart 111.70. The Coast Guard would revise subpart 111.70, Motor
Circuits, Controllers and Protection, to reflect internationally
recognized classification society standards, practices and requirements
which do not rely solely on the shoreside code of the National
Electrical Code. Additionally, the revision will eliminate obsolete
requirements.
Section 111.75-1. The Coast Guard would revise paragraph (a) of
Sec. 111.75-1, Lighting feeders, to replace the term ``fire screen''
with the term ``fire'' to agree with SOLAS 74, and include reference to
low location egress lighting. The Coast Guard would eliminate paragraph
(c). This requirement does not elevate the overall safety level of the
vessel. The Note, however, is part of the section and is retained.
Section 111.75-5. The Coast Guard would delete the voltage specific
requirements of lighting circuits by deleting paragraph (b), Voltages,
in Sec. 111.75-5, Lighting branch circuits, and the remaining
paragraphs would be re-lettered and re-numbered accordingly. The Coast
Guard would redesignate paragraph (c), Connected load, as paragraph (b)
and revise the narrative concerning connected loads. The removed
narrative is standard electrical practice and need not be specified in
the regulations. The Coast Guard would redesignate paragraph (e),
overcurrent protection, as paragraph (d), redesignate paragraph (f), 25
or 30 ampere lighting branch circuits, as paragraph (e), and revise the
new paragraph (d) to remove the specifications for the minimum
conductor sizes. The requirements for these loads required by proposed
revisions of Sec. 111.60-3, Cable application, and Sec. 111.60-4,
Minimum cable conductor size, are adequate. The Coast Guard would
eliminate paragraph (g), connections to screw-shell lampholders, as it
is considered standard practice and need not appear in regulation.
Section 111.75-15. The Coast Guard would revise paragraph (c),
Illumination of passenger and crew spaces, in Sec. 111.75-15 to
eliminate restrictive wording and replace this requirement with a
performance requirement concerning normal habitability and safe egress
under emergency conditions.
Section 111.75-16. The Coast Guard would revise Sec. 111.75-16,
Lifeboat and liferaft floodlights, to replace the terms ``lifeboat''
and ``liferaft'' with the term ``survival craft'' to agree with SOLAS
74 terminology.
Section 111.75-17. The Coast Guard would delete paragraph (d)(1) of
Sec. 111.75-17, Navigation lights, which requires navigation light
fixtures to be approved by the Commandant, as this would no longer be
required. The Coast Guard proposes instead that paragraph (d) be
further revised to incorporate labeling requirements to show compliance
with UL 1104 by an Independent Laboratory. The Coast
[[Page 4138]]
Guard would delete paragraph (f), Light screens. This requirement is
clearly stated in the COLREGS Annex I Rule 5 and in 33 U.S.C. 1602 and
need not be repeated here.
Section 111.75-18. The Coast Guard would revise Sec. 111.75-18,
Signaling lights, to reflect SOLAS 74 Regulation V/11 for applicability
and to reduce specific construction details.
Section 111.75-20. The Coast Guard would revise Sec. 111.75-20,
Lighting fixtures, to modify paragraph (a) to include UL's deleting UL
595 (Marine-Type Electric Lighting Fixtures) and incorporating specific
Marine requirements into the respective fixture type standards (i.e.,
UL 1570 is for Fluorescent Lighting Fixtures, UL 1571 is for
Incandescent Lighting Fixtures, etc.). Also, the Coast Guard would add
an additional paragraph (e) which would address the installation of
non-emergency interior and decorative lighting in environmentally-
controlled spaces. Also, requirements related to shock and vibration
which may be encountered in the marine environment will be addressed.
Both paragraphs will reference additional international standard
options.
Sections 111.77-3, 111.77-5, 111.77-7, 111.77-9, and 111.77-11. The
Coast Guard would eliminate Sec. 111.77-3, Electric cooking equipment,
Sec. 111.77-5, Electric motor-operated appliances, Sec. 111.77-7,
Dishwashers, Sec. 111.77-9, Refrigerators, and Sec. 111.77-11,
Refrigerated drinking water coolers, and replace them with
internationally recognized safety standards. Selection of safe
appliances, based on industry construction and testing standards for
use on commercial vessels, is at the option of the vessel owner.
Section 111.79-1. The Coast Guard would revise Sec. 111.79-1,
Receptacle outlets; general, to remove specific construction
requirements and to allow for more flexibility in installations.
Section 111.79-5. The Coast Guard would eliminate Sec. 111.79-5,
Damp or wet locations and weather locations, and incorporate more
general industry standards and practices under Sec. 111.79-1,
Receptacle outlets; general, in the proposed revision of paragraphs (c)
and (d).
Section 111.79-7. The Coast Guard would remove the detailed
construction requirements for receptacle components in Sec. 111.79-7,
No live parts, and replace them with performance requirements.
Section 111.79-13. The Coast Guard would revise and rename
Sec. 111.79-13, Different potentials on a vessel, to read, Different
voltages and power types, to remove any ambiguity and more clearly
explain the intent of the regulation.
Sections 111.81-1 and 111.81-5. The Coast Guard would delete
Sec. 111.81-5, National Electrical Code, and the text, which addresses
the NEC requirements for outlet boxes and junction boxes, would be
relocated to new paragraph (d) in Sec. 111.81-1, Outlet boxes and
junction boxes: General. The new Sec. 111.81-1(d) would address the
general requirements for junction boxes in terms of U.S. national
standards and introduce the option of international standards as well.
This change would also consolidate the requirements for junction boxes
into one section.
Section 111.81-7. The Coast Guard would rename Sec. 111.81-7,
Degree of protection. The Coast Guard would also propose to revise this
section by incorporating industry accepted standards and terminology,
both domestic and international.
Section 111.81-9. The Coast Guard would revise Sec. 111.81-9,
Mounting, to remove specific installation restrictions and replace them
with performance requirements.
Section 111.81-11. The Coast Guard would eliminate Sec. 111.81-11,
Penetration of walls. This regulation is unnecessary since, by
definition, a watertight enclosure must retain its integrity to be
considered watertight.
Section 111.81-13. The Coast Guard would eliminate Sec. 111.81-13,
Construction. General construction requirements for outlet and junction
boxes are now addressed in proposed paragraphs 111.81-7(a) and (b).
Section 111.83-3. The Coast Guard would remove Sec. 111.83-3,
Spacing: Live parts and live parts and ground, as the subject is
addressed in Sec. 111.01-7, Accessibility.
Subpart 111.85. The Coast Guard would revise subpart 111.85,
Electric Oil Immersion Heaters, to exempt oil immersion heaters where
it can be shown that the operating temperature of the heater can never
reach the ignition temperature of the oil or vapor with which it is in
contact.
Section 111.87-3. The Coast Guard would revise paragraph (a) of
Sec. 111.87-3, General requirements, to remove construction
requirements to specific standards and replace them with reference to
more general safety related requirements.
Subpart 111.89. The Coast Guard would eliminate subpart 111.89,
Motion Picture Projectors. This regulation references a standard that
is no longer pertinent to the marine environment. State-of-the-art
technology has substituted video tape and laser disk players which do
not present the same level of risk as projectors.
Section 111.91-1. The Coast Guard would revise and rename
Sec. 111.91-1, Control and interlock circuits, to require elevator and
dumbwaiter power, control, interlock, and switch circuitry to meet the
requirements of American National Standards Institute, Inc. (ANSI
A17.1).
Section 111.91-3. The Coast Guard would eliminate Sec. 111.91-3,
Control switches. This design standard is not pertinent to the
performance of the device.
Section 111.95-3. The Coast Guard would eliminate the detailed
construction requirements of paragraphs (a) through (e) of Sec. 111.95-
3, General requirements. Paragraph (f) would be renamed (b) and
retained. New general requirements will be set forth in a proposed
revision to reference industry accepted standards (both national and
international) and other proposed requirements for Degree of Protection
and Accessibility.
Section 111.95-5. The Coast Guard would eliminate the detailed
requirements of Sec. 111.95-5, Detail construction requirements.
Sufficient guidance is afforded in the proposed revision of Sec. 111-
95-3, General requirements.
Section 111.95-7. The Coast Guard would delete figures 111.95-7
(e)(1) through (e)(5), which address typical boat winch wiring diagrams
and arrangement drawings. The figures create confusion in the
application of lifeboat davit switches and serve no useful or safety
purpose.
Section 111.97-5. The Coast Guard would revise paragraph (c) of
Sec. 111.97-5, Electric and hydraulic power supply, to reduce the
required capacity of an accumulator tank on a hydraulic system common
to more than one power-operated watertight door. The present regulation
requires the tank to have sufficient capacity to open and close all
doors three times. Consistent with SOLAS 74, the proposed requirement
states that the capacity must be sufficient to close all doors two
times and open all doors once.
Subpart 111.99. The Coast Guard would revise subpart 111.99,
Firescreen Door Holding and Release Systems, to replace the term ``fire
screen'' with the term ``fire'' to provide consistency with the
terminology of SOLAS 74, Regulation II-2/47.
Section 111.99-1. The Coast Guard would expand the scope of
Sec. 111.99-1, Applicability, to address fire doors installed on all
vessels which require fire doors. The subchapters in 46 CFR containing
requirements for specific vessel types all require fire doors to meet
subpart 111.99.
[[Page 4139]]
Subpart 111.105. The Coast Guard would add, delete and revise
sections of subpart 111.105, Hazardous Locations, to reflect current
national standards and recognized classification society rules.
Additionally, means of alternative compliance to these particulars will
be provided by incorporating by reference international standards
(i.e., IEC, CEN and IEEE). Specific paragraphs and sections affected
follow.
Section 111.105-1. The Coast Guard would revise Sec. 111.105-1,
Applicability, to remove the restriction to the National Electrical
Code references to hazardous locations and provide options from IEC
Publication 79 series.
Section 111.105-3. The Coast Guard would add a new Sec. 111.105-3,
General requirements, to provide basic guidance to hazardous location
information and to set forth the appropriate standards.
Section 111.105-5. The Coast Guard would rename the section and
delete the subject material of Sec. 111.105-5, National Electrical
Code, whose guidance has been superseded by proposed new Sec. 111.105-
3. Proposed Sec. 111.105-5, System integrity, would now address the
prohibition of mixing the requirements of the NEC with IEC equipment
and systems since, although equivalent in level of safety, they differ
in the manner by which this is achieved.
Section 111.105-7, 111.105-9, 111.105-11, and 111.105-23. The Coast
Guard would revise Sec. 111.105-7, Approved equipment, Sec. 111.105-9,
Explosionproof equipment, Sec. 111.105-11, Intrinsically safe systems,
and Sec. 111.105-23, Fan motors, to replace the specifically mentioned
test facilities with phraseology that will provide industry with a
greater number of options for product testing.
Section 111.105-10. The Coast Guard would eliminate Sec. 111.105-
10, Purged and pressurized equipment. Its content, with options, would
be sufficiently presented in proposed Sec. 111.105-7, Approved
equipment.
Section 111.105-11. The Coast Guard would revise paragraph (a) of
Sec. 111.105-11, Intrinsically safe systems, to remove the restriction
of specific test laboratories and to add additional accepted
international standards to which equipment may be tested.
Section 111.105-11. The Coast Guard would add paragraphs (b)(3) and
(b)(4) in Sec. 111.105-11, Intrinsically safe systems, as an additional
safety measure and to conform with accepted industry practices as
stated in the IEEE Standard 45. Also, the requirements in Sec. 111.105-
11(e) are to be relocated to proposed Sec. 110.25-1(c)(12) to
consolidate the requirements relating to plan submittal.
Sections 111.105-15 and 111.105-17. The Coast Guard would delete
Sec. 111.105-15, Wiring methods for Class I hazardous locations, and
Sec. 111.105-17, Wiring methods for Class II and Class III hazardous
locations. A new Sec. 111.105-15 entitled, Additional methods of
protection, and a new Sec. 111.105-17 entitled, Wiring methods for
hazardous locations, are proposed. These would permit the use of
conduit systems as allowed by the National Electrical Code and afford a
greater variety of equipment complying with internationally accepted
standards.
Section 111.105-19. The Coast Guard would revise Sec. 111.150-19,
Switches, to conform with reference to proposed revisions which reflect
the acceptance of equipment meeting international standards.
Sections 111.105-21, 111.105-23, and 111.105-25. The Coast Guard
would revise the title and text of Sec. 111.105-21, Fans, to
consolidate the guidance in Sec. 111.105-23, Fan motors, and
Sec. 111.105-25, Ventilation ducts, thereby eliminating those two
sections.
Section 111.105-29. The Coast Guard would revise paragraph (a) In
Sec. 111.105-29, Combustible liquid cargo carriers, to include
requirements for submersible pumps on vessels with combustible liquid
cargoes having flashpoints 60 deg.C or higher. This reflects the
requirements of the International Code for the Construction and
Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code),
which allows for submersible cargo pumps to be used on vessels with a
cargo having a flashpoint exceeding 60 deg.C. The Coast Guard would
add paragraph (c) to include hazardous area classification requirements
for vessels carrying a cargo with a flashpoint of 60 deg.C or higher
which is heated to within 15 deg.C of its flashpoint. This reflects
the requirements of the IBC Code.
Section 111.105-31. The Coast Guard would revise Sec. 111.105-31,
Flammable or combustible cargo with a flashpoint below 60 degrees C
(140 degrees F), liquid sulfur and inorganic acid carriers, to include
information in agreement with the wording and guidance in 33.14
(Electrical Installations on Tank Vessels) of IEEE Standard 45. The
Coast Guard would revise paragraph (e) to include internationally
accepted terminology of the IEC concerning zone descriptions of
hazardous locations. The Coast Guard would revise paragraph (l) by
adding new paragraphs (l)(3) and (l)(4) to include requirements for
electrical installations in hazardous locations on board vessels with
cargoes with flashprints below 60 deg.C in accordance with
international standards.
Section 111.105-32. The Coast Guard would revise the title of
Sec. 111.105-32, Bulk liquefied gas and ammonia carriers, and paragraph
(e), which addresses the requirements for submersible cargo pumps in
bulk liquefied flammable gas and ammonia carriers, and would reference
the requirements of Sec. 111.105-31(d) for submersible pumps.
Section 111.105-35. Presently, when a vessel is issued a
Certificate of Inspection to carry coal, the certificate does not
differentiate between the types of coal. This allows a vessel to carry
both types, bituminous and anthracite coal. The Coast Guard would
revise Sec. 111.105-35 to require that vessels carrying coal of any
type be subject to the same hazardous area classification requirements.
Therefore, the vessel's hazardous area plan should address the worst
case scenario.
Section 111.105-37. The Coast Guard would revise Sec. 111.105-37,
Flammable anesthetics, to reflect a change in name and number of the
referenced NFPA standard.
Section 111.105-39. The Coast Guard would revise and rename
Sec. 111.105-39, Gasoline or other highly volatile motor fuel carried
in vehicles, to reflect current recognized classification society rules
regarding requirements for vessels carrying vehicles with fuel in their
tanks. Additionally, means of alternative compliance to classification
society rules is provided by citing IEC Zone classification.
Section 111.105-40. The Coast Guard would introduce a new
Sec. 111.105-40, Additional requirements for RO/RO vessels, to reflect
current international classification society rules regarding RO/RO
vessels. Additionally, means of alternative compliance is provided by
citing IEC Zone classification.
Section 111.105-41. The Coast Guard would revise Sec. 111.105-41,
Battery rooms, to incorporate the provisions of internationally
recognized IEEE Standard 45.
Section 111.105-45. The Coast Guard would add Sec. 111.105-45,
Vessels carrying agricultural products, to identify hazardous locations
on vessels carrying certain agricultural products in bulk due to the
hazards associated with grain dust. The proposed requirements are
identical to the information published in Navigation and Vessel
Inspection circular (NVIC) 9-84 ``Electrical Installations in
Agricultural Dust Locations'' which has been Coast Guard policy since
this subchapter was last revised.
Section 111.105-47. The Coast Guard would add a new Sec. 111.105-
47, Duct keel ventilation or lighting, to reflect
[[Page 4140]]
international practice by citing recognized classification society
rules for ventilation, lighting and gas detection in special areas such
as pipe tunnels, double bottoms and duct keels.
Subpart 111.107. The Coast Guard would revise subpart 111.107,
Industrial Systems, to define the subject term. The proposed definition
would expand the applicability of industrial systems to vessel types
other than Mobile Offshore Drilling Units. Additionally, the Coast
Guard proposes the general safety requirements of Secs. 111.12-1(b) and
111.12-1(c) for generator prime movers be applied to industrial system
prime movers.
Part 112--Emergency Lighting and Power Systems
Section 112.05-1. The Coast Guard would revise paragraph (a) in
Sec. 112.05-1, Purpose, to remove ambiguity with regard to the purpose
and intent of ensuring a dependable, independent and dedicated
emergency power source. The Coast Guard would add a new paragraph (c)
to allow the Commanding Officer, Marine Safety Center, to authorize
certain electrical loads be connected to the emergency power source.
These include loads that may be required in an emergency due to the
particular mission or configuration of the vessel. When these
additional loads are connected to the emergency power source, the
emergency power source must be sized to handle these loads using a
unity (1.0) service factor or an automatic load shedding scheme which
removes these loads before overloading the emergency source of power.
Section 112.05-5. The Coast Guard would revise paragraph (a) of
Sec. 112.05-5, Emergency power source, to reference possible additional
loads allowed by the Commanding Officer, Marine Safety Center in
accordance with the proposed addition of Sec. 112.05-1(c) above. The
Coast Guard would revise note 1 of Table 112.05-5(a) to be consistent
with ABS rule 4/5.40.4. The Coast Guard would revise paragraph (c),
which addresses the requirements for emergency power installations, to
incorporate a reference to subchapter S (Stability). This would require
a vessel's emergency power installation to function at specific angles
of heel and trim, depending on the vessel type. The Coast Guard would
revise paragraph (d), which addresses the requirements for the
emergency power source, by adding associated transforming equipment and
the emergency switchboard to the list of equipment required to be
located aft of the collision bulkhead, outside the machinery space, and
above the uppermost continuous deck. The Coast Guard interprets SOLAS
74 as requiring the ``emergency source of power'' to include the power
source, any associated transforming equipment, and the emergency
switchboard. This proposed change also prohibits any other equipment
from being located in the same space as the emergency power source and
its associated equipment. The Coast Guard would revise paragraph (e) to
conform with the requirements imposed by SOLAS 74 II-1/43-1.3.
Section 112.15-1. The Coast Guard would revise paragraphs (c), (g),
(j), and (k) of Sec. 112.15-1, Temporary emergency loads, to
incorporate the semantics used in SOLAS 74. Paragraph (p) would be
revised to include gas detection systems. New paragraph (q) would be
added to include lighting for helicopter operations, if installed. New
paragraph (r) would be added to include general emergency alarm power,
reflecting SOLAS 74 requirements in Regulation III/50.
Section 112.15-5. The Coast Guard would revise paragraph (b) in
Sec. 112.15-5, Final emergency loads, to identify the circuits of a
passenger elevator that must be powered from the final emergency power
source regardless of the type of vessel. The Coast Guard would also
revise paragraph (f) to require electrically-driven sprinkler systems,
water-spray extinguishing systems, and the foam system pump to be
powered from the final emergency source of power, paragraph (g) to
include a geared diesel's lube oil pump which was unintentionally
omitted at the last revision of this section, and paragraph (i) to
specifically mention new Global Marine Distress Safety System
installations (GMDSS). The Coast Guard would combine paragraphs (j),
(k), (l), (m), and (n) into a single paragraph concerning navigation
aids, all of which are either required or recommended by international
practice. This change will allow a degree of latitude in eliminating
unnecessary navigation equipment from that required to be powered from
the final emergency power source. As a result of this change,
paragraphs (o), steering gear feeders, (p), general alarm, (q), blow-
out preventer, (r), diving systems, (s), emergency generator starting
air compressor, and (t), steering gear failure alarm, of this section
would be re-lettered as paragraphs (k), (l), (m), (n), (o), and (p).
The Coast Guard would add paragraphs (q), (r), (s), (t), (u), and (v)
to require that the following be powered from the final emergency
source: the ballast control systems on column-stabilized MODUs, the
automation loads required by part 62 of this chapter, motor-operated
valves for cargo and fuel oil systems if the emergency source of power
is their source of power to meet Sec. 56.50-60(d), stabilizer wing
positioning motors and indicators and smoke extraction fans and
CO2 exhaust fans.
Section 112.39-1 and 112.39-3. The Coast Guard would eliminate
paragraph (a)(4) of Sec. 112.39-1, General, as Sec. 112.39-3,
Operations, sufficiently defines the performance requirements of the
lanterns. The Coast Guard would revise paragraph (a) of Sec. 112.39-3,
Operation, to conform with SOLAS 74 Regulation II-1/42-1.
Section 112.43-1. The Coast Guard would revise paragraph (b) of
Sec. 112.43-1, Switches, to change a reference from a deleted section
to an active section.
Sections 112.43-3 and 112.43-7. The Coast Guard would delete
Sec. 112.43-3, Controls; general, and rename Sec. 112.43-7, Navigating
bridge distribution panel. The Coast Guard would revise certain entries
in paragraph (a) to make terminology consistent with SOLAS 74. The
present Sec. 112.43-3 repeats the requirements of Sec. 112.43-7.
Section 112.43-5. The Coast Guard would revise Sec. 112.43-5,
Controls on island type vessels, to replace the terms ``lifeboat'' and
``liferaft'' with the term ``survival craft'' to agree with SOLAS 74.
Section 112.43-11. The Coast Guard would revise Sec. 112.43-11,
Illumination for launching operations, to replace the terms
``lifeboat'' and ``liferaft'' with the term ``survival craft'' to agree
with SOLAS 74.
Section 112.43-15. The Coast Guard would revise Sec. 112.43-15,
Emergency lighting feeders, to replace the term ``firescreen'' with the
term ``fire'' to agree with SOLAS 74.
Section 112.43-17. The Coast Guard would delete Sec. 112.43-17,
Emergency light markers. The requirement that all emergency lights be
individually marked is overly restrictive and does not provide a
significant safety feature.
Section 112.45-5. The Coast Guard would relocate the requirements
of Sec. 112.45-5, Test switch, to subpart 111.30, Switchboards. This
proposed change would consolidate the requirements for equipment
required to be on the emergency switchboard in one section.
Section 112.50-1. The Coast Guard would combine paragraphs (d) and
(e) in Sec. 112.50-1, General, to clarify that diesel or gas turbine
engines used to power emergency generators must not have any starting
aids, except a thermostatically-controlled electric water-jacket heater
connected to the final emergency bus. Additionally, the
[[Page 4141]]
time for the emergency generator to be capable of carrying its full
load is increased from 20 to 45 seconds to agree with SOLAS 74.
Sections 112.50-1, 112.50-3, 112.50-5, and 112.50-7. The Coast
Guard would add new paragraph (k) of Sec. 112.50-1 to include
requirements for starting devices on emergency generating sets. SOLAS
74, Regulation II-1/44, requires that ``Each emergency generating set
arranged to automatically start shall be equipped with starting devices
approved by the administration with a stored energy capability of at
least three consecutive starts. A second source of energy shall be
provided for an additional three starts within 30 minutes unless manual
starting can be demonstrated to be effective.'' The proposed change
parallels the International Association of Classification Societies
(IACS) interpretation and affects Sec. 112.50-3, Hydraulic starting;
Sec. 112.50-5, Electric starting; and Sec. 112.50-7, Compressed air
starting which are therefore being revised.
Section 112.55-15. The Coast Guard would revise Sec. 112.55-15,
Capacity of storage batteries, to reflect the requirements of SOLAS 74
regarding opening and closing of watertight doors. This is similar to
the change proposed to subpart 111.97, Electric Power-Operated
Watertight Door Systems, which addresses hydraulic opening and closing
of watertight doors.
Part 113--Communication and Alarm Systems and Equipment
Subpart 113.10. The Coast Guard would revise the title of subpart
113.10, Fire Detecting and Alarm Systems and Manual Fire Alarm Systems,
to include smoke detecting systems.
Section 113.10-7. The Coast Guard would revise Sec. 113.10-7,
Connection boxes, to introduce alternative methods of compliance by
referencing standards of construction of the IEC.
Section 113.10.9. The Coast Guard would revise paragraph (a) of
Sec. 113.10-9, Power supply, to align fire detection system equipment
requirements according to international practice, and remove paragraph
(c).
Section 113.20-3. The Coast Guard would change the title of
Sec. 113.20-3, Watertight equipment, to a more general term, Connection
boxes, to introduce alternative methods of compliance by referencing
the construction standards of the IEC.
Section 113.25-6. The Coast Guard would revise paragraphs (d) and
(e) of Sec. 113.25-6, Power supply. In view of technological advances
in electronic simulation and our acceptance of IEC voltages, the 6-120
volt requirement is unnecessarily restrictive. Additionally, since
SOLAS 74 Regulation III/50 requires the general emergency alarm to be
powered from the main and emergency source, the Coast Guard proposes to
refer to that regulation in this paragraph instead. Paragraph (e) would
contain wording to retain battery, temporary emergency bus and
communication switchboard options.
Section 113.25-8. The Coast Guard would revise paragraphs (b), (c),
(f) and (g) in Sec. 113.25-8, Distribution of general alarm system
feeders and branch circuits, to remove the restriction of having only
five general alarm bells on a branch circuit. The existing regulation
used an arbitrary number to ensure that the branch circuit was not
overloaded. The specific reference to fuses will be replaced by a
general statement regarding overcurrent protection. The remaining
requirements ensure that a circuit is not compromised by a fault in
another part of the vessel. Additionally, the size of vertical zones,
mentioned in paragraph (g), is changed to meet the accepted main
vertical fire zone dimension.
Section 113.25-9. The Coast Guard would revise paragraph (b) of
Sec. 113.25-9, Location of general alarm bells, to remove the detailed
acoustic specifications. These specifications are replaced with more
general performance requirements in proposed new paragraph (c).
Section 113.25-10. The Coast Guard would revise Sec. 113.25-10,
Location of flashing red lights, to include existing policy that only
general alarm beacons, used in high noise areas, be red. This is
required so that personnel are not confused by the use of the same
visual signal to indicate a number of conditions.
Section 113.25-11. The Coast Guard would revise Sec. 113.25-11,
Contact makers, to remove the detailed construction requirements for
the general alarm contact maker. The performance requirements for this
component remain in effect.
Section 113.25-12. The Coast Guard would revise Sec. 113.25-12,
Vibrating bells, to allow the use of electronic devices to simulate the
sound produced by a vibrating bell.
Section 113.25-16. The Coast Guard would revise Sec. 113.25-16,
Fuses, to have this regulation apply to circuit breakers and fuses,
both of which are allowable overcurrent devices.
Subpart 113.30. The Coast Guard would revise subpart 113.30, Sound
Powered Telephone and Voice Tube Systems. Voice tubes will be
eliminated and, owing to today's technology, the Coast Guard will allow
for choices by recognizing systems of communications other than sound
powered phones that are accepted by recognized classification society
rules.
Section 113.30-1. The Coast Guard would revise Sec. 113.30-1,
Applicability, to require self-propelled Mobile Offshore Drilling Units
meet the same requirements as other self-propelled vessels.
Section 113.30-5. The Coast Guard would revise paragraphs (a), (d),
(g), (h), and (i) of Sec. 113.30-5, Requirements, to generalize
communication systems and to incorporate the necessary clarifications
pertinent to Mobile Offshore Drilling Unit applications. The Coast
Guard would add new paragraph (j) to the list of locations where common
means of voice communication and calling are required. This requirement
increases the level of safety aboard the vessel and is consistent with
the requirements of SOLAS 74.
Section 113.30-20. The Coast Guard would revise paragraphs (a),
(b), and (d) (paragraph (d) will be relettered as (c)) of Sec. 113.30-
20, Sound-powered telephone systems: General requirements, to correct
the semantics of referencing ``communications systems'' versus only
``sound-powered phones''.
Section 113.30-25. The Coast Guard would revise paragraph (a) of
Sec. 113.30-25, Sound-powered telephone system; detailed requirements,
to remove the requirement that sound-powered telephones be approved by
the Commandant. The remaining regulations are sufficient to ensure
proper installation and operation of sound-powered telephones, or other
reliable means of voice communications and calling.
Section 113.35-3. The Coast Guard would revise paragraph (e)(3) of
Sec. 113.35-3, General requirements, to reflect the above change in
interior communications terminology.
Sections 113.35-5 and 113.35-7. The Coast Guard would revise
Sec. 113.35-5, Electric engine order telegraph systems; general
requirements, and Sec. 113.35-7, Electric engine order telegraph
systems; detailed requirements, to eliminate the detailed design
specifications for electric engine-order telegraph systems. These two
sections are combined under Sec. 113.35-5 to produce a single section
addressing performance requirements.
Sections 113.35-9 and 113.35-11. The Coast Guard would revise
Sec. 113.35-9, Mechanical engine order telegraph systems; general
requirements, and Sec. 113.35-11, Mechanical engine order telegraph
systems; detailed requirements, to eliminate the detailed design
specification for mechanical
[[Page 4142]]
engine-order telegraph systems. These two sections are combined under
Sec. 113.35-9 to produce a single section addressing performance
requirements.
Section 113.37-5. The Coast Guard would correct semantics
concerning ``navigating bridge'' versus ``wheelhouse'' in Sec. 113.37-
5, General requirements.
Section 113.37-10. The Coast Guard would remove paragraphs (b),
(c), and (d) in Sec. 113.37-10, Detailed requirements. Most of these
requirements represent standard marine practice, thereby making
regulation unnecessary. New paragraph (b) would restate present
paragraph (c)'s watertight requirement with international standard
option.
Section 113.40-10. The Coast Guard would revise Sec. 113.40-10,
Detailed requirements, to add clarifying language that rudder-angle
indicator circuits must be separate and independent from the autopilot
and the dynamic positioning system as well as the steering gear control
system. The Coast Guard would also remove paragraphs (b), (c), (d),
(e), and (f) in this section. Most of these requirements represent
standard marine practice, thereby making regulation unnecessary. New
paragraph (b) would restate present paragraph (e)'s watertight
requirement with international standard options.
Sections 113.43-3 and 113.43-5. The Coast Guard would revise
paragraph (a) of Sec. 113.43-3, Alarm system, and (b) of Sec. 113.43-5,
Power supply, by substituting ``navigating bridge'' for ``pilothouse''
or ``wheelhouse''.
Subpart 113.50. The Coast Guard would revise and rename subpart
113.50, Emergency Loudspeaker Systems, to read, Public Address Systems,
in order to incorporate performance requirements which are now in
subchapter Q, subpart 161.004. The Coast Guard would eliminate
subchapter Q, subpart 161.004. These proposals are consistent with
SOLAS 74 III/6.4.
Subpart 113.65. The Coast Guard would revise subpart 113.65,
Whistle Operators, to correct the reference to IEEE Standard 45.
Subpart 113.70. The Coast Guard would eliminate subpart 113.70,
Smoke Detector Systems. This equipment is now included with Fire
Detecting Systems in the proposed revision to Sec. 113.10.
Part 161--Electrical Equipment
Subpart 161.002. The Coast Guard would extensively revise subpart
161.002, Fire-Protective Systems, in order to eliminate overly
restrictive construction requirements and to provide for options in the
manufacture and testing of fire and smoke detecting and alarm systems
via internationally accepted standards.
Subpart 161.004. The Coast Guard would delete subpart 161.004,
Emergency Loudspeaker System. The performance requirements would be
incorporated into subpart 113.50, which would be renamed Public Address
Systems. SOLAS 74 Regulation III/6-4.2 requires every vessel that has a
general alarm to have a public address system (or other suitable means
of communications) to supplement the general alarm.
Incorporation by Reference
Material that would be incorporated by reference throughout
subchapter J is listed in Sec. 110.10-1. Copies of the material are
available for inspection where indicated under ADDRESSES. Copies of the
material are available from the sources listed in Sec. 110.10-1.
Before publishing a final rule, the Coast Guard will submit this
material to the Director of the Federal Register for approval of the
incorporation by reference.
Regulatory Evaluation
This proposal is not a significant regulatory action under section
3(f) of Executive Order 12866 and does not require an assessment of
potential costs and benefits under section 6(a)(3) of that order. It
has not been reviewed by the Office of Management and Budget under that
order. It is not significant under the regulatory policies and
procedures of the Department of Transportation (DOT) (44 FR 11040,
February 26, 1979).
The Coast Guard expects the economic impact of this proposal to be
so minimal that a full Regulatory Evaluation under paragraph 10e of the
regulatory policies and procedures of DOT is unnecessary.
The Coast Guard has found that most of the changes to the
Electrical Engineering Regulations are either editorial or they update
technical specifications to reflect the latest practices. There are
some regulatory changes that will require different construction.
Although some of these changes will cause minor cost increases for
shipbuilders, others will result in substantial savings. Many of the
proposed rulemaking changes causing cost increases are already current
marine industry practice. The remaining changes causing cost increases
are more than offset by the cost savings offered by several relaxations
in the regulations.
Overall, it is anticipated that there will be a net cost reduction
offered for vessels constructed under these rules, but the exact impact
is difficult to determine accurately since it may vary from vessel to
vessel. For certain vessels, new requirements may increase costs, but
the application of national and international industry consensus
standards should enhance performance and thus increase the level of
safety. Additionally, due to cost decreases that may result from the
removal of the requirements for armor on cable, allowance of the use of
NEC and IEC motors, and a variety of circuit breakers conforming to
international standards in panelboards, it may be possible to
significantly lower costs for each vessel. Actual savings will depend
upon the industry practices followed by each vessel designer/shipyard
before and after the effective date of these regulations.
In addition to the savings in material costs, there are several
intangible benefits. Due to the increased reference to national and
international standards other than the National Electrical Code and
Underwriters Laboratories Inc., certain equipment items will now be
more readily available ``off the shelf'' for marine use. The proposed
regulations will reduce the regulatory burden on the marine industry,
purge obsolete and out-of-date regulations, and eliminate requirements
that create an unwarranted differential between domestic rules and
international standards.
The Coast Guard expects that significant economic savings will
result from the ability of equipment manufacturers, in many cases, to
meet performance specifications instead of design standards and the
elimination of the need to submit to the U.S. Coast Guard detailed
plans and specifications for approval for equipment such as sound
powered telephones, emergency loudspeaker systems, and navigation
lights.
The Coast Guard solicits cost data and comments regarding the
economic impact of these proposed requirements from all interested
parties.
Small Entities
Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the
Coast Guard must consider whether this proposal, if adopted, will have
a significant economic impact on a substantial number of small
entities. ``Small Entities'' may include (1) small businesses and not-
for-profit organizations that are independently owned and operated and
are not dominant in their fields and (2) governmental jurisdictions
with populations of less than 50,000.
The Coast Guard believes it has addressed the concerns of many
small
[[Page 4143]]
entities by the adoption of wide variety of national and international
standards regarding system arrangement. Additionally, the proposed
regulations will dramatically revise certain prescriptive electrical
equipment design, specification, and approval requirements, and replace
them with performance-based requirements that incorporate international
standards.
Whenever possible, requirements have been adjusted to the size of
the vessel and in some cases a relaxation of requirements for smaller
vessels has been offered. Due to the flexibility of requirements in
these proposed rules and the eliminating of regulatory burden, small
entities involved in the building or ownership of vessels should
experience increasing business opportunities.
Collection of Information
Under the Paperwork Reduction Act (44 U.S.C. 3501 et. seq.), the
Office of Management and Budget (OMB) reviews each proposed rule which
contains a collection-of-information requirement to determine whether
the practical value of this information is worth the burden imposed by
its collection. Collection-of-information requirements include
reporting, recordkeeping, notification, and other, similar
requirements.
This proposed rule contains collection-of-information requirements
in the following subparts: subpart 110.25 in subchapter J and subparts
161.002 and 161.010 in subchapter Q. The following particulars apply to
subpart 110.25:
DOT No.: 2115.
OMB Control No.: 2115-0115.
Administration: U.S. Coast Guard.
Title: Electrical Engineering Regulations--Subchapter J.
Need for Information: This proposed rule would require amendments
to the regulations, clarify the regulations, bring them up to date, and
delete unnecessary requirements. The revisions to subchapter J will
reduce the reliance on domestic standards and will adopt SOLAS 74 and
other international standards developed through consensus by the
international maritime community.
Proposed Sec. 110.25-1 would require industry to complete
electrical engineering plans to meet performance requirements on new-
built vessels and modifications of current vessels. These requirements
will help resolve much of the confusion during inspections which has
risen due to the complexity of electrical system arrangements on modern
merchant vessels.
Proposed Use of Information: The reporting of this information is
necessary to ensure compliance with electrical engineering safety
regulations. Through the review of the design plans prior to
construction, the vessel owner or builder may be assured that the
vessel, if built in accordance with the plans, will meet regulatory
standards.
Frequency of Response: The various information called for in
Sec. 110.25 would be reported on occasion. Design plans will only be
submitted when there is construction of new-built vessels or
modification of current vessels.
Burden Estimate: 478 hours.
Respondents: 175 owners or operators.
Average Burden Hours per Respondent: 1 hour per submission.
The following particulars apply to subparts 161.002 and 161.010:
DOT No.: 2115.
OMB Control No.: 2115-0121.
Administration: U.S. Coast Guard.
Title: Equipment, Construction, and Materials: Specifications and
Approval--Subchapter Q.
Need for Information: This proposed rule world require amendments
to the regulations, clarify the regulations, bring them up to date, and
delete unnecessary requirements. The revisions to subchapter Q will
required industry to maintain records of production tests for some fire
protection systems. These plans consist mainly of system/material tests
that are necessary to determine that the equipment being used in the
construction of a fire protection system meets the minimum performance
requirements.
The following is a section-by-section justification of the
collection requirements.
Proposed subpart 161.002 would require manufacturers to complete
electrical specifications to meet performance requirements for fire
protection systems. This requirement will help identify specific
equipment approved and to permit the production of equipment identical
to the equipment samples originally tested.
Proposed Use of Information: The reporting of this information is
necessary to ensure compliance with electrical system arrangement/
equipment and fire protection system regulations. Through the review of
approval plans, the manufacturer may be assured that the material or
device, if manufactured in accordance with the material specifications,
will meet regulatory standards.
Frequency of Response: The various information called for in
subpart 161.002 would be reported on occasion. Approval for equipment
will only be submitted when production tests are required.
Burden Estimate: 60 hours.
Respondents: 6 manufacturers.
Average Burden Hours Per Respondent: 10 hours per respondent.
The Coast Guard has submitted the requirements to OMB for review
under section 3504(h) of the Paperwork Reduction Act. Persons
submitting comments on the requirements should submit their comments
both to OMB and to the Coast Guard where indicated under ADDRESSES.
Federalism
The Coast Guard has analyzed this proposal under the principles and
criteria contained in Executive Order 12612 and has determined that
this proposal does not have sufficient federalism implications to
warrant the preparation of a Federalism Assessment.
Environment
The Coast Guard has considered the environmental impact of this
rule and concluded that, under paragraphs 2.B.2e(34)(d) and (e) of
Commandant Instruction M16475.1B, this rule is categorically excluded
from further environmental documentation. This rule concerns only
system arrangement and equipment approval. The approved system
arrangement and equipment required by this rule should contribute in
the enhancement of vessel safety, and thereby help to minimize any
impact to the marine environment. A ``Categorical Exclusion
Determination'' is available in the docket for inspection or copying
where indicated under ADDRESSES.

Corrosion resistant material or finish means any material or finish
which meets the testing requirements of ASTM B-117 or test Kb in IEC
68-2-52 for 200 hours and does not show pitting, cracking or other
deterioration more severe than that resulting from a similar test on
passivated AISI Type 304 stainless steel.
Corrosive location means any location exposed to the weather on
vessels operating in salt water or locations onboard which may be
exposed to the corrosive effects of the cargo carried or by any of the
vessel's systems.
Dead ship condition is the condition in which the main propulsion
plant, boilers and auxiliaries are not in operation due to the absence
of power.
Dripproof means enclosed so that equipment meets at least a NEMA
Type 1 with dripshield, NEMA Type 2 or an IEC IP 32 rating.
