Electrical Engineering Requirements for Merchant Vessels

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purge obsolete and out-of-date regulations, and eliminate requirements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

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.
