Electrical Engineering Requirements for Merchant Vessels

SUMMARY: As part of the President's Regulatory Reinvention Initiative,

the Coast Guard is amending 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out-of-date regulations, and eliminate requirements that create an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 rulemaking harmonizes, 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 rulemaking dramatically revises certain prescriptive

electrical equipment design, specification, and approval requirements

and replaces them with performance-based requirements that incorporate

international standards.

DATES: This final rule is effective June 16, 1997. The incorporation by

reference of certain publications listed in the rule is approved by the

Director of the Federal Register on June 16, 1997.

ADDRESSES: Documents as indicated in this preamble are available for

inspection or copying at the office of the Executive Secretary, Marine

Safety Council (G-LRA/3406), U.S. Coast Guard Headquarters, 2100 Second

Street SW., room 3406, Washington, DC 20593-0001, between 9:30 a.m. and

SUPPLEMENTARY INFORMATION:

Regulatory History

On February 2, 1996, the Coast Guard published a notice of proposed

rulemaking (NPRM) entitled ``Electrical Engineering Requirements for

Merchant Vessels'' in the Federal Register (61 FR 4132). There were two

correction notices published for the NPRM on February 23, 1996 (61 FR

7050), and March 5, 1996 (61 FR 8539). The Coast Guard received 45

letters commenting on the proposal. As a result of requests from a

national trade association, a notice was published on February 26, 1996

(61 FR 7090), extending the comment period from March 18, 1996, to

April 2, 1996, and announcing a public meeting on March 25, 1996. Over

20 persons attended the meeting and 9 commented on the NPRM. A

recording and summary of the meeting are in the rulemaking docket. On

June 4, 1996, the Coast Guard published an interim rule in the Federal

Register (61 FR 28260).

Correction notices were published on June 26, 1996 (61 FR 33045),

July 3, 1996 (61 FR 34927), July 11, 1996 (61 FR 36608), July 12, 1996

(61 FR 36786), July 30, 1996 (61 FR 39695), and September 23, 1996 (61

FR 49691), in the Federal Register. Also, the Coast Guard published a

notice of policy on October 4, 1996 (61 FR 51789), in the Federal

Register. The Coast Guard received 30 letters commenting on the interim

rule. No public meeting was requested, and none was held.

Drafting Information

The principal persons involved in drafting this document are Mr.

Gerald P. Miante, Office of Design and Engineering (G-MSE-3), and Mr.

Stephen H. Barber, Project Counsel, Office of Chief Counsel.

Purpose

Under the authorities cited in the ``Authority'' section for each

part amended, the Coast Guard is amending its electrical engineering

and equipment regulations for certain Coast Guard-inspected vessels in

46 CFR chapter I, subchapters I-A, J, and Q to accomplish the

following:

(1) To reduce the regulatory burden on the marine industry by

eliminating obsolete and unnecessary regulations and by clarifying the

remaining ones. This objective is consistent with the President's

Regulatory Reinvention Initiative and the Coast Guard's regulatory

reform program.

(2) To replace, where appropriate, requirements that are

prescriptive in nature with performance-based requirements that

incorporate national or international standards and allow increased

flexibility for small businesses.

(3) To eliminate requirements that create an unwarranted

differential between domestic rules and international standards. This

rulemaking harmonizes, where possible, the electrical engineering

regulations with amendments to the International Convention for the

Safety of Life at Sea, 1974, (SOLAS 74) since the electrical

engineering regulations were last revised in 1982.

(4) To address comments received from the marine industry and from

Coast Guard field and inspection offices.

This rulemaking is intended to serve the needs of industry while

maintaining a comparable level of safety.

Discussion of Comments and Changes

The following is a summary of the comments received and the changes

made to the regulatory text since the interim rule was published. The

items are grouped first by those that address a general issue, then by

those that relate to a specific provision in the text.

I. General Comments.

(1) Several comments congratulated the Coast Guard for its revision

of subchapter J which offers the manufacturers more flexibility,

increases clarity of the regulations and enhances safety of U.S. flag

vessels. It was observed that the revision process reflects a lot of

``hard work and good common sense.''

(2) As in response to the NPRM, a number of comments recommended

changes that may require further consideration by the Coast Guard.

Several comments recommended that certain other standards be referenced

in the regulations as replacements for, or options to, those cited in

the interim rule. However, not all changes could be incorporated at

this final rule stage, due to the complexity of the requests or the

necessity to allow the public an opportunity to comment on new

requirements. Several additional standards for incorporation by

reference are included in this final rule.

The Coast Guard has a long-range plan to broaden the use of

acceptable standards. Until those standards are incorporated into the

regulations, any vessel owner or operator who desires to employ a

fitting, material, apparatus, equipment, or arrangement other than that

required by this subchapter may submit a request using the equivalency

provision in Sec. 110.20-1.

Items the Coast Guard may consider for a subsequent rulemaking

include--

(a) Incorporation of the new Institute of Electronic and Electrical

Engineers (IEEE) Std 45, when approved by the IEEE standards board and

published;

(b) Addition of a requirement that all manufacturer's conducting

self-certification should be International Organization for

Standardization (ISO) 9001 registered;

[[Page 23895]]

(c) Incorporation of performance-based inclination criteria into

Sec. 111.01-19;

(d) Consideration of requirements for high impedance grounding

systems to be added to Sec. 111.05-19;

(e) Establishing a new subpart that would address the necessary

supply of clean, uninterrupted power for modern AC-powered, solid-state

equipment, which would complement the requirements of Secs. 111.15-3

and 111.20-1;

(f) Addition of a ventilation alarm requirement to Sec.

111.35-1.

(g) Prohibition of screw-in, porcelain or glass-cap fuses in

subpart 111.53;

(h) Incorporation of new standards that provide guidance for high

voltage cable in Sec. 111.60-1(e);

(i) Incorporation of the Canadian Standards Association

(CSA) flame test CSA FT-4 either as another option or in place of

American National Standards Institute/Underwriters Laboratories (ANSI/

UL) 1581 test VW-1 in Secs. 111.60-2 and 111.30-19(b)(4);

(j) Incorporation of Underwriters Laboratories (UL) 2225 into

Sec. 111.60-23(h) to provide guidance on the use of metal-clad (Type

MC) cable in hazardous (classified) locations;

(k) Incorporation of Illuminating Engineers Society

(IES) Recommended Practice (RP) 12 for marine lighting in Sec.

111.75-15(c);

(l) Permission of third-party testing for lighting, appliances, oil

immersion heaters, and electric heaters in Secs. 111.75-20, 111.85-1,

and 111.87-3;

(m) Incorporation of International Electrotechnical

Commission (IEC) 1892 in Sec. 111.105-5 for electrical

installations aboard mobile offshore drilling units (MODU's) and

floating platforms;

(n) Incorporation of pump room ventilation and monitoring

requirements of American Bureau of Shipping (ABS), Rules for Building

and Classing Steel Vessels, section 4/5.151.6 into Sec. 111.105-31;

(o) Replacing IEC 332-3, Category A flame test with IEC 332-3,

Category A/F in Sec. 111.107-1;

(p) Restricting the color red for general emergency or fire alarms

only in Sec. 113.25-10;

(q) Application of the cable routing and fire testing requirement

of Sec. 113.30-25(i) to all safety related circuits in part 113;

(r) Incorporation of additional requirements in Sec.

113.50-20 to align the regulations with the International Maritime

Organization (IMO) Code of Alarms and Indicators; nd

(s) Establishing a new subpart 113.70 for gas detection systems.

(3) A number of comments commended the Coast Guard's effort to

streamline its electrical regulations and incorporate industry

standards, both domestic and international.

Consistent with the President's Regulatory Reinvention Initiative,

the Coast Guard is taking this approach in all its rulemaking projects.

(4) Two comments voiced several specific concerns and requested

extending the effective date of the interim rule by six months to allow

the U.S. shipbuilding community an opportunity to compile detailed

comments and suggestions regarding the change. Additionally, the

comment specified major concerns relating to degree of protection

requirements for enclosures, ambient temperatures for equipment, ground

detection regulation, and marine battery installations.

In response, the Coast Guard, after a detailed analysis of these

concerns, determined that the extension of the comment period was

unnecessary. In response to the comment's specific concerns and until

this final rule could be finalized, the Coast Guard published a notice

of policy for interim rule (61 FR 51789; October 4, 1996). This policy

notice pointed out that persons wishing to apply a provision from the

1996 draft of IEEE Std 45 or the 1996 ABS Rules for Building and

Classing Steel Vessels instead of a provision in the interim rule could

submit, for approval on a case-by-case basis, a request under the

equivalency provisions in the interim rule.

(5) One comment requested clarification on what standards are

approved for incorporation by reference and who determines if a

standard is approved.

The Coast Guard determines which standards are acceptable for

incorporation by reference. In order to use a system arrangement or

individual piece of equipment that does not meet the standards

incorporated by reference or the specific requirements in this

subchapter, a request may be submitted under the equivalency provision

of Sec. 110.20-1. Requests under the equivalency provision will be

considered at the time a specific system design is submitted to the

Coast Guard for plan review and may be accepted as part of the system

plan approval.

(6) Several comments indicated that, contrary to the Coast Guard's

intentions, the interim rule significantly increases the cost of doing

business internationally for U.S. shipyards. They expressed concern

that equipment protection, temperature, and operational characteristic

requirements have been increased beyond conventional practice. Due to

this perceived increase in requirements, the comments stated that

electrical equipment might require extensive additional testing to

demonstrate operability. These comments also noted that the

requirements for alarm, indicating and internal communications systems

have been greatly expanded. Finally, the comments pointed out that the

interim rule invokes requirements that did not previously exist and are

not found in trade literature. The comments' specific concerns are

addressed in the discussion of comments for the relative section.

Generally, however, the perceived increases and changes to the

requirements in the final rule are actually a harmonization of the

Coast Guard's electrical engineering requirements with classification

society (ABS) and international (IEC) performance-based standards.

(7) One comment expressed concern that the Coast Guard is heavily

reliant on ABS Rules when the ABS Rules may not be aligned with the

requirements of the International Association of Classification

Societies (IACS) Member Societies. Also, the comment expressed concern

that the regulations unfairly forced Member Societies to follow ABS

requirements for vessels operating in U.S. waters.

The Coast Guard has traditionally incorporated by reference various

sections of ABS Rules into its electrical engineering regulations. This

rule expands on the use of ABS Rules as an option or alternative to

prescriptive requirements. However, the incorporation by reference of

specific ABS rules does not preclude the use of other rules approved

for specific applications under the equivalency provisions in

Sec. 110.20-1.

Additionally, port state control inspections are performed mainly

to determine compliance with SOLAS 74 and some related Coast Guard

regulations. The requirements of subchapter J and its referenced

material apply to Coast Guard-certificated, U.S.-flag vessels only and

are not generally applicable to foreign vessels, unless specified

elsewhere in Coast Guard regulations.

(8) One comment recommended incorporating more performance-based

standards and more Coast Guard policies to reduce the number of

requests seeking equivalency determinations under these regulations.

The comment expressed belief that adherence to performance standards

[[Page 23896]]

will foster greater innovation and improved overall safety.

Throughout the regulation, the Coast Guard has incorporated,

wherever possible, a significant number of additional industry

standards, both domestic and international. Time and resource

limitations prevent the inclusion of every applicable standard. The

allowance of equivalencies would permit the inclusion of appropriate

standards that the Coast Guard has yet to review. This practice does

foster innovation and is consistent with the Coast Guard's intention to

serve the needs of industry while maintaining a comparable level of

safety.

(9) Several comments pointed out that, at the time of the

publication of the interim rule, which incorporated the 1995 ABS Rules

for Building and Classing Steel Vessels, ABS had already published the

1996 edition of these rules.

The text of this final rule incorporates the ABS Rules for Building

and Classing Steel Vessels, 1996 edition. ABS updated section 4/5 of

the ABS Rules for Building and Classing Steel Vessels by incorporating

international requirements and, at the same time, reorganized the

section into a more user-friendly format by dividing it into parts and

renumbering the paragraphs.

II. Comments to Specific Sections

Section 110.01-3. (1) Now that the rule is finalized, the option of

complying with regulations in effect at the time the alterations or

modifications are made has been removed from paragraph (b). Compliance

with this regulation is now mandatory.

(2) Paragraph (c) has been amended to better define the term

``conversion.''

Section 110.10-1. (1) One comment suggested incorporating by

reference IEEE Recommended Practice on Surge Voltages in Low-Voltage AC

Power Circuits (IEEE Std 62.41-1991); UL 1449, Standard for Transient

Voltage Surge Suppressors; and UL 1778, Standard for Uninterruptable

Power Supply Equipment.

These standards apply to uninterruptable power supplies (UPS) which

are not presently addressed in these regulations. While the value of

these standards are realized and their use is not prohibited by these

regulations, the Coast Guard will not include specific provisions or

requirements on this subject in this rule without allowing an

opportunity for public comment.

(2) One comment suggested that American Petroleum Institute (API)

Recommended Practices (RP) should not be incorporated into these

regulations because they set forth domestic practices for fixed

platform and shoreside facilities and do not reflect international

consensus for vessels. It was suggested to consider incorporation of

IEC 1892, which is presently under development at an international

level.

The Coast Guard agrees and is awaiting the publication of the IEC

standard for review. The Coast Guard may consider IEC 1892 in a

subsequent rulemaking where the public will have an opportunity to

comment. Until its publication, subchapter I-A, subparts 111.105 and

111.107, of this chapter and Coast Guard policy provide guidance for

MODU's and other Outer Continental Shelf (OCS) vessels.

Section 110.15-1. (1) One comment recommended that the definition

of ``independent laboratory'' be changed to clarify that the

certification may not be performed in the absence of listing.

The intent of the definition is to ensure that testing must always

be performed but also recognizes that laboratories vary in the

terminology of promulgating successful results. Certain laboratories

``list'' products; other laboratories ``certify'' that products meet

certain standards.

(2) One comment suggested that the requirement for watertight

enclosures of National Electrical Manufacturers Association (NEMA) Type

6 or 6P is excessive and suggested that NEMA Type 4 or 4X most closely

matches the IEEE Std 45 definition of watertight and exceeds the

definition of waterproof.

The Coast Guard agrees and the definitions of ``watertight'' and

``waterproof'' have been revised in accordance with IEEE 100. Examples

of industry accepted minimum degrees of protection requirements are

included.

(3) One comment stated that the increase in the degree of

protection requirements for ``dripproof'' to IEC ingress protection

(IP) 32 will cause manufacturers to redesign electrical installations

aboard vessels; and IEC IP 22 is acceptable as the current industry

standard. Additionally, the comment recommended reinstating NEMA 250

Type 12 in this category.

The Coast Guard agrees with all the recommendations and the

definition of ``dripproof'' has been revised accordingly.

Section 110.25-1. (1) One comment recommended adding wording to

paragraph (i)(6) to clarify that, when required by the standard, proof

of listing and certification must also be submitted. This change would

align the regulatory language with the note to the same section.

Paragraph (i)(6) has been revised accordingly.

(2) Several comments suggested that, in the note to paragraph (n),

items required to meet an industry standard should only be certified by

an independent laboratory approved by the Commandant, and not simply

self-certified by the manufacturer. One comment pointed out that

elimination of this requirement would result in inferior equipment

severely jeopardizing shipboard safety. The comment suggests that at a

bare minimum any manufacturer conducting self-certification should be

ISO 9001 registered, which requires third-party evaluation of the

manufacturer's quality program.

Before the recent revisions of subchapter J, the regulation in this

area required proof of listing only for equipment required to meet UL

standards; manufacturer's self-certification was allowed for other

standards such as IEEE, NEMA, and ANSI. The interim rule modified this

requirement by consolidating UL into the latter group. The Coast Guard

may consider requiring manufacturers, who wish to self-certify, to be

ISO 9001-registered in a subsequent rulemaking where the public will

have an opportunity to comment.

(3) One comment recommended removing from paragraph (c) Marine

Safety Center (MSC) review of components to expedite review and

eliminate redundant review by the MSC and the Officer in Charge, Marine

Inspection (OCMI). The comment states that the certificate of

inspection is a better measure of safety.

The inspection for certification of a vessel cannot be conducted at

the component level for most systems. The Coast Guard has a long-

standing policy to allow plan review by third parties, such as

professional engineers and ABS, with oversight functions distributed

between the MSC and OCMI. The Coast Guard continues to find component

verification by the MSC necessary for these essential systems.

Section 111.01-1. One comment suggested adding wording to prohibit

the use of combustible materials in the construction of electrical

equipment, for example, enclosures and foundations.

It is Coast Guard policy, which is congruent with SOLAS 74,

Regulations II-2/34 and 49, to avoid the unnecessary use of combustible

materials. Therefore, new paragraph (b) has been added to this section.

Section 111.01-9. (1) Several comments noted that, in paragraphs

(a) and (c), IEC IP 32 is an unduly severe degree of protection instead

of a NEMA 250 Type 2 enclosure and that IEC IP 22

[[Page 23897]]

is acceptable as the current industry standard.

The Coast Guard agrees and has revised paragraphs (a) and (c)

accordingly.

(2) Several comments suggested that the Coast Guard incorporate by

reference table 4/5B.1 of the 1996 ABS Rules for Building and Classing

Steel Vessels as acceptable minimum degrees of protection.

This table has been added to paragraph (b) and to the note to this

section.

(3) Several comments pointed out that the degree of protection

requirements NEMA 250 Type 6 or 6P and IEC IP 67 are too severe to be

designated as ``watertight''.

The Coast Guard agrees and has revised the requirement to be NEMA

250 Type 4 or 4X and IEC IP 56 in paragraph (b) of this section and

wherever the watertight requirement appears in part 113 of this

chapter.

(4) One comment suggested that an addition be made to these

regulations to avoid the possibility that the National Electrical Code

(NEC) requirements for land-based equipment near seashores might exceed

requirements in this subchapter.

This subchapter addresses Coast Guard certificated vessels. Land-

based electrical installations fall under different standards and are

not subject to this subchapter. The Coast Guard is not responsible for

the development of NEC requirements.

Section 111.01-15. (1) Several comments pointed out that, in

paragraph (c), circuit breakers be allowed to be rated at 40 deg.C

instead of 45 deg.C because this is in accordance with marine circuit

breakers covered in UL 489, supplement SA incorporated into

Sec. 111.54-1(b) of this chapter. This would not preclude the option of

using 50 deg.C Navy type circuit breakers.

Paragraph (c) has been revised accordingly.

(2) One comment suggested that requiring a 55 deg.C rating for all

control and instrumentation equipment will cause manufacturers to

recertify and redesign equipment.

The increase to 55 deg.C rating for these critical circuit

elements is in harmony with ABS Rules for Building and Classing Steel

Vessels, table 4/11.1, IEC 68, and IEC 92-101, table 4. Therefore, the

requirement is retained.

(3) One comment noted that an ambient temperature of 40 deg.C

differs with the generally accepted IACS and IEC temperature of 45

deg.C.

The Coast Guard has accepted 40 deg.C electrical equipment with

specific exceptions in areas of special concern as noted in this

section.

Section 111.01-17. One comment noted that the regulations establish

new requirements and vendor testing to demonstrate operability.

These requirements conform to the international standard IEC 92-101

and 1996 ABS Rules for Building and Classing Steel Vessels, table 4/

5.1.

Section 111.01-19. (1) One comment suggested that if the Coast

Guard were to provide a performance-based inclination criteria, the

result would be the elimination of equivalency determinations

applicable to any single class of vessel.

No performance criteria were submitted in response to the interim

rule; however, the Coast Guard may consider any performance criteria

submitted for incorporation into a subsequent rulemaking.

(2) One comment recommended changing the wording to exclude certain

items, such as dishwashers, toasters, and coffee makers, that are not

necessary to the maneuvering and safety of the vessel.

This section has been revised to apply these requirements to

critical equipment and systems.

(3) One comment stated that the new requirements, which ensure that

all electrical equipment is operable under certain extreme conditions

of list, roll, and trim, will result in greater expense due to the

installation of new equipment requiring additional tests.

Although this section has been revised to apply to critical

systems, the inclination requirements are consistent with IEC 92-101,

table 3.

Section 111.05-7. (1) One comment noted that this section is

redundant to Sec. 111.60-5.

This section is retained because of its specific reference to

armored cable and grounding.

(2) One comment recommended removing the reference to IEC 92-3

because this standard does not address installation guidance for armor

and sheathing.

The reference to IEC 92-3 is retained because several sections of

Part 3 of the IEC publication, such as clauses 10.18 and 11.14, provide

guidance for metallic armor and sheathing.

Section 111.05-9. One comment recommended incorporating the

American Boat and Yacht Council (ABYC) Standard E4 on lightning

protection.

The Coast Guard agrees that guidance is appropriate for lightning

protection. The Coast Guard is incorporating the international standard

IEC 92-401, Electrical Installations in Ships; Part 401: Installation

and test of completed installation, section 10, Lightning Conductors.

Section 111.05-19. One comment recommended additions to the

regulation for permitting high-impedance grounding schemes on all

vessels with a distribution voltage greater than 1,000 volts a.c. as

this method becomes an important tool for circuit protection, fault

coordination, and the limitation of equipment damage.

While the value of this practice is realized and its use is not

prohibited by these regulations, the Coast Guard will not include

specific provisions or requirements on this subject in a final rule

without allowing an opportunity for public comment. However, this final

rule references this grounding method in Secs. 111.05-19 and 111.05-27.

Section 111.05-23. (1) One comment suggested allowing either the

ground detecting equipment or an alarm signal from the detecting

equipment to be installed at the distribution switchboard via a control

cable instead of bringing back a phase conductor to the main

distribution switchboard. Also, the comment points out that allowing

the detection equipment to remain near the transformer would also make

it available for local troubleshooting.

While this is the intent of paragraph (d), a note has been added to

the paragraph for clarification.

(2) One comment recommended that paragraph (d) should be revised to

include only isolation devices greater than 10 kVA.

Paragraph (d) has been revised to specify ``feeder'' circuits,

regardless of the load.

(3) One comment suggested that the increase in the required number

of ground detector lights will have a great impact on the cost and

space.

The revisions to paragraph (d) discussed previously should address

the concern of this comment by reducing the number of circuits

monitored and method of monitoring.

Section 111.05-27. One comment stated that the requirement to

momentarily remove the indicating device is overly prescriptive and

recommended a more performance-based requirement to permit new

technology.

The section has been revised to clarify intent.

Section 111.05-33. (1) Several comments suggested revising this

section to clarify safety grounds (bonding) versus system grounds so

the language is technically accurate.

This section has been revised accordingly.

[[Page 23898]]

(2) Several comments noted that clarification is necessary in

paragraph (b) to exclude ``system'' ground conductors which are

required by Coast Guard policy to be equal in size to the current

carrying conductors.

Paragraph (b) has been revised accordingly.

(3) One comment recommended revising the requirement to allow cable

armor and Type MC cable sheath as a grounding conductor as long as the

cable is third-party tested and listed (with its terminators) as

approved for this application.

Coast Guard historically has prohibited the use of marine shipboard

cable braided armor or metallic sheath as the grounding conductor. Type

MC cable installation is required to be in accordance with the NEC as

stated in Sec. 111.60-23 of this chapter.

Section 111.10-1. One comment requested a definition for the term

``auxiliary propulsion'' since certain types of thrusters are designed

for use as ``take-home'' propulsive devices and thrusters are

specifically excluded from paragraph (a).

The term ``auxiliary propulsion'' is revised to read ``propulsion

auxiliary'' to clarify that the intended machinery includes items such

as fuel oil service pumps, lube oil service pumps, purifiers, engine

sea water and fresh water cooling pumps, and air ejection equipment.

Non-conventional systems must be reviewed on a case-by-case basis to

consider such a thruster or ``take-home'' motor in a systems

relationship with the power generating equipment capacity.

Section 111.10-9. One comment stated that propulsion and vessel

control are the critical components of the specified loads. The comment

noted that absent these systems, and given the ability of many safety

systems to operate in the absence of distributed electric power, the

additional redundancy and expense of two independent transformers is

not justified.

Most vessels rely on distributed electric power for system

operation. Plans for any non-conventional system which does not rely on

power from the transformers may be submitted for review in accordance

with Sec. 110.20-1.

Section 111.12-1. (1) One comment suggested that the Coast Guard

accept other major classification societies besides ABS to eliminate

differential between domestic rules and international standards.

According to the comment, ABS Rules create a burden on equipment

manufacturers with additional ``type-testing.''

The Coast Guard has traditionally incorporated by reference various

sections of ABS Rules into its electrical engineering regulations. This

rule expands on the use of ABS Rules as an option or alternative to

Coast Guard prescriptive requirements. However, the incorporation by

reference of specific ABS rules does not preclude the use of other

rules approved for specific applications under the equivalency

provisions in Sec. 110.20-1, whereby the Coast Guard can consider

alternative ``type-testing.''

Since ABS is a member of IACS and has recently revised its

electrical section 4/5 (section 4/3 of the ABS Rules for Building and

Classing Mobile Offshore Drilling Units) to incorporate many IEC

practices, the Coast Guard considers prime movers meeting these

sections to be aligned with international standards.

(2) One comment noted that neither Coast Guard regulations nor ABS

Rules provide for automatic shutdown of a diesel generator's prime

mover upon failure of that engine's pressure lubrication system.

The requirement in paragraph (c) of this section is retained

because, in addition to being sound engineering practice, table 4/11.10

of the 1996 ABS Rules for Building and Classing Steel Vessels provides

for automatic shutdown of diesel, steam, and gas turbine prime movers

upon low lube oil inlet pressure to that engine as well as to the

bearings of the electrical generator.

Section 111.12-11. One comment recommended adding a new item to

paragraph (c) which would require the circuit breaker for a generator

to open upon the shutting down of the prime mover. This is a safety

feature required by ABS Rules for Building and Classing Steel Vessels,

1996, section 4/5A5.3.1.

The inclusion of a low-voltage trip element, activated upon the

shutting down of the prime mover, has always been a feature on

generator circuit breakers and in the provisions of ABS Rules; however,

this requirement has been absent from Coast Guard regulations.

It is now added in new paragraph (c)(1).

Section 111.15-2. (1) One comment noted that the requirements of

this section will cause the U.S. marine industry to use specialized,

more expensive batteries. Also, the addition of a special nameplate

will increase costs.

The Coast Guard utilizes regulations, incorporating Classification

Society Rules and standards, to ensure that equipment aboard

certificated vessels is suitable for the environment and the purpose

for which it is installed. This is particularly applicable to equipment

used in cases of emergency. Labeling of the product by the manufacturer

to attest to certain conditions is a cost effective method of

presenting this information to shipowners, operators, crew, and

inspectors.

(2) One comment recommended the use of a more performance-based

standard instead of the specific requirements in paragraph (a).

Performance standards would preclude the necessity for equivalency

determinations for column stabilized units, surface effects vessels,

etc.

The requirement of 40 degrees of inclination is consistent with IEC

92-101 and 92-305. Although a parameter for use of accumulator

batteries in ships, a unit designed for the environmental conditions of

marine installation should include this feature. The use of an

accumulator battery that does not meet this parameter may be requested

under the equivalency provision of Sec. 110.20-1. Submissions under the

equivalency provision will be considered at the time a specific system

design is submitted to the Coast Guard for plan review and may be

accepted as part of the system plan approval.

Section 111.15-3. One comment suggested the addition of a three

pole disconnect switch located in the battery compartment of large

battery installation with a nominal voltage of higher than 120 volts

for use during servicing.

This comment applies mainly to a large amount of cells for use with

uninterruptable power supply units and may be considered for inclusion

into a subsequent rulemaking where the public will have an opportunity

to comment.

Section 111.15-5. (1) One comment noted that, in paragraph (c),

batteries are allowed in confined spaces if the batteries are sealed.

The comment recommended that no batteries, sealed or otherwise, should

be situated in confined areas because these units are only ``sealed''

if everything is normal and may vent as much as standard cells under

abnormal conditions.

Paragraph (c) has been revised accordingly.

(2) One comment suggested that, in paragraph (e), it is sufficient

for a battery to have indication of manufacturer and type number on the

battery with documentation available to support the ampacity,

construction, and specific gravity requirements.

Battery documentation is usually obscure and unavailable for

service personnel and inspectors and labeling is considered necessary

for maintenance and inspection.

[[Page 23899]]

Section 111.15-20. One comment recommended that, if the Coast Guard

is going to specify ampacity considerations, then it should also

specify a voltage drop in the criteria for cable sizing.

Paragraph (c) has been revised to include the words ``while

maintaining the proper voltage at the load end.''

Section 111.15-30. One comment indicated that the purpose of this

section is unclear and appears to be directed at a unique situation.

The purpose of this section is to ensure that, from a systems

engineering perspective, battery installations and their chargers are

compatible. It also cautions against the use of some portable battery

chargers which may impose an unintentional ground of the vessel's power

supply system. Section 111.15-30 is retained.

Section 111.20-1. (1) One comment suggested revising the

requirement to allow only transformers rated at less than 500 VA to be

installed in an enclosure as an alternative to the winding being

inherently resistant to moisture, sea atmosphere, and oil vapor. It

reasons that the long term integrity of enclosures for larger,

permanently fixed transformers may not survive the life cycle of the

vessel.

This section is retained because it offers alternatives for this

equipment. Should the enclosure choice be selected, design, plan

review, installation, and inspection must all show suitability for

environmental conditions and applicability to the system in which it is

used.

(2) One comment recommended revising the provision to allow an

exception for inherently current limiting ferro-resonant transformers

which are incorporated in a device meeting UL 1778.

The Coast Guard determined that this equipment is for specific use

and uninterruptable power supplies. As stated previously,

uninterruptable power supplies will be addressed in the next revision

of the electrical engineering regulations. Until that time, use of

uninterruptable power supply systems are not specifically prohibited by

these regulations, and their usage is subject to the normal plan review

and inspection process.

Section 111.30-5. (1) One comment noted that IEC 92-302 and 92-503

do not define low and medium voltages but refer to voltage ranges. Only

IEEE defines the terms.

Paragraph (a) has been revised accordingly.

(2) One comment suggested moving paragraph (b) to Sec. 111.01-9,

Degrees of protection.

Paragraph (b) specifically addresses dripping and falling

substances, whereas, Sec. 111.01-9 addresses the universal enclosure

requirements as outlined in the referenced standards.

Sections 111.30-9, 111.30-11, and 111.30-13. One comment

recommended that the provisions of these sections be reinstated. The

comment suggests that these operational safety standards should be set

as clear Coast Guard standards. The comment expressed a concern that if

a crew member were to remove an insulated floor matting or grating for

cosmetic reasons, the potential threat to safety would not be in

violation to any clear cut Coast Guard requirement; only a violation to

an obscure reference in a secondary document which might not be aboard

the vessel.

The features described in the previously removed Secs. 111.30-9

(doors and non-conducting handrails) and 111.30-13 (grounding of

switchboard instrumentation) are all construction features to be

installed by the manufacturer in accordance with applicable standards.

In reference to previously removed Sec. 111.30-11 (mats or gratings),

the Coast Guard agrees that this is an important operational safety

concern and that specific guidance is warranted. The reinstated

performance-based requirement reflects international standards.

Section 111.30-19. (1) One comment suggested adding punctuation to

paragraph (b)(3) to clearly distinguish between switchboard wire and

instrumentation wire.

Paragraph (b)(3) has been revised accordingly.

(2) Several comments indicated that paragraph (b)(6) and

Sec. 111.60-11, paragraph (d) cross-reference each other for

switchboard wiring and leave the requirements for switchboard wiring

undefined.

The requirements for switchboard wiring are found in paragraph (b)

and its referenced standard. The cross-reference to Sec. 111.60-11 was

unnecessary and has been removed.

(3) One comment recommended changing the wire size in paragraph

(b)(3) to #18 AWG to align with Sec. 111.60-4.

The #14 AWG wire size requirement in this section is specific to

switchboard wiring, whereas the #18 AWG allowance in Sec. 111.60-4 is

for general wiring such as lighting fixtures or other uses where

appropriate.

Section 111.30-21. One comment recommended retaining this section

with modifications to allow devices which operate at elevated

temperatures, but are self-cooling and do not adversely affect

surrounding components.

The Coast Guard determined that the requirements removed from the

regulations are sufficiently addressed in the relevant construction

standards.

Section 111.30-24. One comment requested clarification on the word

``floating.''

As discussed in the preamble to the interim rule, on page 28264, a

comment to the NPRM requested that exclusion for a non-self propelled

MODU be expanded to include other OCS facilities. Since subchapter J is

not universally applicable to fixed platforms, the Coast Guard accepted

the comment's suggestion to specify ``floating'' units which are

subject to the provisions of this subchapter such as tension leg

platforms (TLP) and semi-submersible production platforms.

Section 111.30-25. Two comments noted that this section, which was

not addressed in the NPRM or the interim rule, is highly prescriptive

and limits the use of newer technologies.

The Coast Guard has determined that any new equipment resulting

from advances in technology that performs the same function as those

devices listed in Sec. 111.30-25 can be considered for approval under

Sec. 110.20-1. The list in Sec. 111.30-25 is retained because the Coast

Guard determined it to be representative of those functions necessary

for the safe operation of a vessel.

Section 111.33-11. One comment recommended specifying that ``ABS

Rules'' refers to the ABS Rules for Building and Classing Steel

Vessels.

The Coast Guard agrees and has changed the reference from ``ABS

Rules'' to ``ABS Rules for Building and Classing Steel Vessels.''

Additionally, the reference to ``ABS MODU Rules'' has been changed to

``ABS Rules for Building and Classing Mobile Offshore Drilling Units.''

Section 111.35-1. One comment requested a revision to this section

that requires an alarm indicating the failure of system ventilation.

The Coast Guard may consider adding a requirement for an alarm

indicating the failure of a ventilation system in a subsequent

rulemaking where the public will have an opportunity to comment.

Section 111.40-1. One comment noted that the deletion of this

section would result in the installation of panelboards never intended

for the marine environment. The comment suggests incorporating IEEE Std

45 to provide guidance for the construction of panelboards.

[[Page 23900]]

The Coast Guard agrees and is adding the suggested reference

because of its wide acceptance in the marine field.

Section 111.51-3. One comment pointed out that wording is missing

from this section which would ensure proper protective device

coordination in all cases and round out the coordination declaration

made in Sec. 111.51-1.

The Coast Guard agrees and the section is revised accordingly by

the addition of new paragraph (a).

Section 111.53. One comment suggested adding specific wording that

prohibits the use of any fuse holder constructed of porcelain or

ceramic materials or any fuse that is of the screw-in type.

The Coast Guard is reviewing the safety implications of screw-in

type fuses and may consider prohibiting those fuses in a subsequent

rulemaking where the public will have an opportunity to comment.

Section 111.54-1. One comment suggested referencing IEC 56 for

circuit breakers above 1000 volts in place of the reference in

paragraph (c)(3)(ii) to IEC 947-2 for medium voltage circuit breakers.

The Coast Guard agrees that the appropriate standard for circuit

breakers above 1000 volts is IEC 56. Paragraph (c)(3)(ii) is revised

accordingly.

Section111.60-1. (1) One comment noted that in paragraph (a) the

word ``cooper'' should be changed to the word ``copper.''

Paragraph (a) has been revised accordingly.

(2) Several comments requested reinstatement of MIL-C-915F cable

pointing out that this is a current Navy standard and another comment

suggested further the addition of ``amendment 2'' to the MIL

specification.

The Naval Sea Systems Command (NAVSEA) electrical office has

informed the Coast Guard that MIL-C-915 cable is not being installed in

new construction or major modifications. Additionally, its supply of

MIL-C-915 cable has been cut-up and sold for scrap.

(3) One comment suggested that marine shipboard cable listed by a

Nationally Recognized Testing Laboratory (NRTL) accepted by the

Commandant is acceptable for use.

The term ``NRTL'' is most commonly used by Occupational Safety and

Health Administration (OSHA) for safety-type testing, whereas cable

testing includes physical testing as well as fire testing. The Coast

Guard maintains a list of independent testing laboratories accepted by

the Commandant for this purpose. Present Coast Guard policy is

consistent with the suggestion.

(4) One comment suggested deleting the terms ``construction'' and

``identification'' from paragraph (a) and recommended that all cable

must meet the performance requirements in IEEE Std 45.

As stated in paragraph (d), all electrical cable must now meet the

performance requirements of section 18 of IEEE Std 45.

(5) One comment recommended for inclusion in paragraph

(f) Type TC and Type ITC cables for industrial applications.

Section 111.107-1 contains the regulations for industrial systems

and cables. Special purpose or ship-specific equipment can be accepted

as equivalent under Sec. 110.20-1 during plan review.

(6) One comment recommended that incorporating IEC 92-3, removing

the words ``and identification'' from paragraph (a), and removing the

words ``and marking'' from paragraph (d) would result in economical

cables for shipbuilders. If this is not an option, the comment suggests

that the Coast Guard accept the minimum markings instead of requiring

the more extensive markings of IEEE Std 45.

The Coast Guard has determined that the minimum marking

requirements are those in IEEE Std 45. The IEEE Std 45 markings

constitute the five basic pieces of information necessary for minimum

identification.

(7) One comment suggested deleting paragraph (d) because it

unnecessarily adds additional performance requirements to material and

finished products which have met its particular standard.

Paragraph (d) is retained because it ensures IEEE Std 45

performance standards are met and guarantees that minimum safety

criteria are upheld.

(8) One comment suggested an editorial change in paragraph (f) to

correctly reference the IADC standard as an application standard.

Paragraph (f) has been revised accordingly.

(9) One comment recommended that in paragraph (e) the regulation

should specify a standard for high-voltage cable that is acceptable to

the Coast Guard.

Presently, IEEE Std 45 and IEC 92-3 as well as several MIL

specifications and UL 1072 form the acceptable standards. The Coast

Guard may consider IEC 92-354 and IEC 502 in a subsequent rulemaking

where the public will have an opportunity to comment.

Section 111.60-2. (1) One comment suggested deleting the reference

to ANSI/UL 1581 test VW-1 because it does not guarantee a degree of

flame propagation resistance such as the other specifications mentioned

in this section. It recommended replacing it with an alternate test CSA

FT-4.

The flammability tests in this section are retained. The Coast

Guard may consider test CSA FT-4 in a subsequent rulemaking where the

public will have an opportunity to comment.

(2) One comment suggested that it is not necessary to physically

separate specialty cable from other cable in all installations.

Paragraph (a) requires physical separation only if the flammability

tests in the introductory text of this section cannot be met.

(3) One comment recommended paragraph (b) be applied only to cable

runs installed in enclosed locations.

Cable that cannot meet minimum flammability requirements must

comply with both paragraphs (a) and (b) to reduce the risk of flame

spreading among cable runs and throughout the vessel.

Section 111.60-3. Several comments suggested revising paragraph (d)

to encompass special applications referred to throughout section 19 of

IEEE Std 45 and not limiting the focus on the particular application in

19.6.5 of the standard.

Paragraph (d) has been revised accordingly.

Section 111.60-4. One comment noted that the listed metric

conversions of AWG sizes do not correspond to standard metric wire

sizes. The comment suggests listing standard metric wire sizes that are

acceptable in lieu of the AWG sizes.

The metric sizes that accompany AWG numbers are provided as

approximate metric dimensions and are ``soft'' conversions from the AWG

circular mil equivalents. Actual metric nominal size is found to differ

between such standards as JIS and European. Also, other wire gauge

systems exist such as British Standard and Birmingham whose nominal

sizes and actual dimensions differ from AWG and metrics. Electrical

plans are reviewed and approved by the Coast Guard usually with an AWG

size listed and annotated with ``or equivalent.'' It is up to the

designer to choose a cable with conductors capable of equal or greater

ampacity which will pass final inspection upon installation.

Sec. 111.60-11. (1) One comment suggested modifying the section

title to read ``Wire (other than ground conductors).''

The Coast Guard determined that this change is unnecessary because

this

[[Page 23901]]

section is self-explanatory and grounding conductors are covered

elsewhere.

(2) One comment recommended qualifying the word ``enclosure'' as

``equipment enclosure.''

The Coast Guard determined that the suggested clarification is

unnecessary because wire is allowed in junction boxes, controllers, and

switchboards as well as equipment enclosures, for example, lighting

fixtures and motors.

(3) One comment suggested revising paragraph (c) to reference the

appropriate standards for wire relative to IEEE Std 45.

Paragraph (c) has been revised accordingly.

Sec. 111.60-17. (1) One comment suggested including specific

requirements for crimped ferrules or pin terminals to prevent loose

strands of wire causing shorts when used with compression type

terminals.

The Coast Guard determined that this is an installation quality

control issue addressed under the general requirements in Sec. 111.10-1

for electrical installations.

(2) Several comments recommended prohibiting twist-on type

connectors, recommended including a referenced standard or method of

securing them to prevent loosening, or recommended eliminating

paragraph (b).

The Coast Guard determined that this, again, is an installation

quality control issue addressed under the general requirements in

Sec. 111.10-1 for electrical installations. Twist-on connectors must be

installed in accordance with this entire section; safety is maintained

with proper installation. Industry has requested, and Executive Order

12866 demands, that government agencies include more performance-based

requirements rather than prescriptive regulation. Section 111.60-17 is

an example of the inclusion of a performance-based standard and

presents an allowance for other methods or new technology which meet

the same criteria.

Sec. 111.60-19. One comment recommended revising paragraph (a) to

allow temporary splices within an enclosure in hazardous locations for

repair operations necessitated by damaged cable, where replacement of

such damaged cable would shut down vessel operations. The spliced cable

run could then be replaced at a later date while the vessel is in a

shipyard.

The Coast Guard takes into consideration the economic conditions

and mission of the vessels it regulates, but its primary concern is the

safety of these vessels and their crews.

It is the responsibility of certain persons in charge of a vessel

to notify the Coast Guard in the event of a marine casualty, accident,

or serious marine incident. The cognizant OCMI will determine the

course of action to be taken, notwithstanding temporary repairs of an

emergency nature which might be deemed necessary by the master.

Sec. 111.60-23. (1) Several comments applauded the proposal to

allow limited use of Type MC cable. One comment noted that Type MC

cable had been used in the marine environment for more than 20 years.

It states that Type MC cable meeting the standards as proposed provides

an acceptable alternative while maintaining safety.

(2) One comment expressed concern that a disproportionate number of

comments support the prohibition or restriction of Type MC cable in

marine locations.

The Coast Guard determines regulatory policy based on the substance

of comments, rather than the number of comments, on a subject.

(3) Several comments recommended that instrument tray cable (ITC)

(300 volt insulation) with similar Type MC cable construction be

allowed where allowed by NEC standards.

Article 90-2(b) of the NEC states that the code does not generally

cover installations on vessels. NEC standards do not apply to Coast

Guard certificated vessels, unless specifically incorporated by

reference in this subchapter.

Alignment with NEC standards is not necessarily an objective of

this rulemaking. ITC cable has not been evaluated for use aboard

vessels.

(4) One comment noted that Sec. 111.60-23(a) refers to ``vessels''

whereas paragraphs (c)(2) and (g) refer to ``offshore floating drilling

and production facilities.''

The term ``vessel'' is broadly defined in section 3 of title 1 of

the U.S. Code to include floating production units, mobile offshore

drilling units, and ships. Paragraphs (c)(2) and (g) apply only to

offshore floating, drilling and production facilities.

(5) Several comments suggested that the word ``welded'' as used in

the term ``continuously welded corrugated metal-clad (CWCMC) cable'' be

removed throughout Sec. 111.60-23 to conform with commercial

terminology. This will provide a continuous impervious corrugated metal

sheath manufactured by either the extrusion or welded process.

The term ``continuously welded corrugated metal-clad (CWCMC)

cable'' in paragraph (a) has been changed to ``continuous corrugated

metal-clad cable'' and paragraph b(1) and paragraph (h) have been

changed accordingly.

(6) One comment questioned why only corrugated as opposed to non-

corrugated Type MC cable is allowed.

Non-corrugated Type MC cable does not have the flexibility

necessary for use on vessels or floating facilities. Corrugated cable

would be less susceptible to cracking under these conditions.

(7) Several comments recommended that the requirement for the UBVZ

listing on Type MC cable be removed. One comment stated that the UBVZ

listing does not affect construction of the cable or its suitability

for use on vessels, but does affect cable pricing and availability.

The Coast Guard agrees. The UBVZ listing has been removed from

paragraph (b). This removal is also consistent with the Coast Guard's

position that metal-clad cable is a code product and not a marine

shipboard cable.

(8) One comment recommended that the term ``impervious'' in

reference to the sheath of the cable be changed to ``gas/vaportight''

because ``gas/vaportight'' is an NEC term.

The terms ``gas-tight'' and ``vapor-tight'' have been added for

clarity.

(9) One comment suggested that the term ``close-fitting'' be

removed as undefined.

The words ``close-fitting around the conductors and fillers'' have

been added for clarity.

(10) One comment stated that paragraph (b) was unclear as to what

an independent laboratory was to certify or list.

Paragraphs (b)(2) and (b)(3) have been combined to correct this

discrepancy.

(11) Two comments recommended that the restrictions for

Type MC cable in paragraph (c)(1) should be moved to Sec. 111.60-3

because they are applicable to all cables.

Type MC cable must be treated separately because it is not suitable

for applications such as elevators. Marine shipboard cable, described

in Sec. 111.60-1, must be used for all the services in paragraph (c).

(12) Two comments suggested that Type MC cable should be allowed in

drilling function areas as it is recognized by API RP 14F for use on

fixed production facilities.

API RP 14F applies only to fixed facilities. This subchapter does

not apply to fixed facilities.

(13) Several comments recommended removing paragraphs (c)(2) and

(g). They contend that these paragraphs are prescriptive and are

already covered

[[Page 23902]]

under the performance standard in paragraph (c)(1).

Paragraphs (c)(1) and (c)(2) have been combined for clarity and

paragraph (g) is retained. The Coast Guard does not allow the use of

Type MC cable in areas that are inherently subject to high vibration or

the other conditions specified in paragraph (c).

(14) Several comments suggested that installation of Type MC cable

not be limited to article 334 because other articles within the NEC are

also applicable.

The other applicable articles are already referenced in article

334.

(15) Two comments recommended the acceptance of table A6 of IEEE

Std 45 as well as the ampacity tables given in the NEC since both are

based on the same method of calculation.

Type MC cable is a code product, to be installed in accordance with

article 334 of the NEC and, therefore, the NEC's ampacity tables are to

be used.

(16) Several comments suggested that the metallic sheath of Type MC

cable be allowed for use as a grounding conductor.

The Coast Guard determined that there is insufficient historical

data on the use of Type MC cable on vessels to allow the metallic

sheath to be used as a grounding conductor. Even on shipboard cable,

the Coast Guard has never allowed braided armor to be used as a

grounding conductor. The Coast Guard maintains this policy with Type MC

cable.

(17) Many comments suggested removing the prohibition of the use of

Type MC cable as interconnection between drilling and production

modules.

The Coast Guard has revised paragraph (g) to allow Type MC cable to

be used as interconnection between drilling and production modules on

the same platform. Type MC cable is still prohibited as interconnection

between temporary drilling packages and platform production modules.

(18) The Coast Guard is aware of the recently published UL 2225,

Metal-Clad Cables and Cable-Sealing Fittings For Use in Hazardous

(Classified) Locations, and may consider it as a reference in paragraph

(h) in a subsequent rulemaking where the public will have an

opportunity to comment.

(19) One comment recommended that paragraph (h) be revised to avoid

confusion between terminations and fittings for Type MC cable and those

for similar cable, such as TECK.

Paragraph (h) has been revised to assure that fittings and

terminations used must be compatible with the particular Type MC cable

used.

Section 111.70-1. One comment stated that it is unsafe to allow one

phase to remain connected in ungrounded three-phase alternating current

systems.

Paragraph (b) of this section refers to the controller/motor

overload relay and not the main disconnect device to isolate the

controller/motor from the power source. Paragraph (a) includes a

reference to ABS Rules for Building and Classing Steel Vessels

addressing the main disconnect and its relationship to the motor-

running protective devices. Additionally, language has been added to

paragraph (b) to clarify that the opening of two phases refers to the

controller/motor overload devices.

Section 111.70-3. (1) One comment suggested a revision to paragraph

(d)(1), by replacing ``and'' with ``or'' to clarify that when both a

controller and motor control center exist the identification

information should only be required at one of the two.

Motor control centers group individual controllers into a central

location instead of installing each controller locally near its motor.

Normally, the use of one precludes the use of the other for a

particular motor.

(2) One comment suggested eliminating items (v) and (vii) in

paragraph (d)(1) and listing information sufficient to identify the

motor controlled, its load, voltage and phase.

The requirements in paragraph (d)(1) are consistent with IEEE Std

45 and in keeping with standard engineering practice to provide

important information necessary for the safe operation of the

electrical system.

Section 111.70-7. One comment recommended an editorial change in

paragraph (d)(2) concerning the requirements of the disconnect device.

Paragraph (d)(2) has been revised accordingly.

Section 111.75-5. One comment recommended that in paragraph (b) the

term ``lamp sizes'' be changed to ``fixture ratings'', and retain the

minimum 50 watt requirement for convenience receptacles or IEEE Std 45,

paragraph 21.6 be referenced.

Paragraph (b) has been revised accordingly.

Section 111.75-15. One comment indicated that the text of paragraph

(c) is vague, providing no firm guidance. The comment suggests

incorporating IES RP 12, Recommended Practice for Marine Lighting.

The Coast Guard may consider IES RP 12 in a subsequent rulemaking

where the public will have an opportunity to comment.

Section 111.75-17. (1) One comment suggested that the term ``range

light'' in paragraphs (b) and (c) either needs to be defined or

replaced with the term ``masthead light.''

The Coast Guard agrees and is removing the term ``range light''

which is now referred to in the Convention on International Regulations

for Preventing Collisions at Sea, 1972 (72 COLREGS) as ``a second

masthead light.''

(2) One comment recommended the inclusion of specific photometric

requirements for battery powered navigation lights.

The Navigation Safety Advisory Committee (NAVSAC) reviewed the

adequacy of lighting on barges, which is generally powered by battery,

and concluded that no lighting requirement changes were necessary.

Section 111.75-20. (1) One comment recommended revising paragraph

(a) so that it is clear that the paragraph does not apply to lighting

fixtures in hazardous locations.

The Coast Guard is revising paragraph (a) accordingly.

(2) Two comments suggested replacing the term ``meet'' with the

term(s) ``listed/certified'' to provide a means of verifying compliance

with any industry standard and requiring lighting fixtures to be tested

by an independent third party.

It is Coast Guard policy that when a referenced standard requires

testing then the procedure is part of the regulation. Since the Coast

Guard maintains a process of independent laboratory acceptance by the

Commandant for items such as fire detection systems, cable, and marine

lighting fixtures, it is also part of our policy that such testing be

certified at these laboratories. The Coast Guard may consider third

party testing in a subsequent rulemaking where the public will have an

opportunity to comment.

Section 111.85-1. One comment recommended that each oil immersion

heater be tested by an independent third party testing institution.

An added requirement for compliance with a specific standard and

subsequent testing by a third party cannot be placed in this final rule

without opportunity for public comment. Recognizing the safety

implications of the equipment, the Coast Guard may consider the

inclusion of applicable safety standards and testing arrangements for a

subsequent rulemaking where the public will have an opportunity to

comment. Presently, guidance is afforded to both manufacturer and user

in subpart 111.01 of this chapter which establishes general criteria

for all electrical equipment so that it is appropriate for the

[[Page 23903]]

environment and purpose for which it is installed.

Section 111.87-3. One comment suggested that in paragraph (a)

deleting the word ``meet'' and substituting the words ``listed/

certified.''

It is Coast Guard policy that when a referenced standard requires

testing then the procedure is part of the regulation. Since the Coast

Guard maintains a process of independent laboratory acceptance by the

Commandant for items such as fire detection systems, cable, and marine

lighting fixtures, it is also part of our policy that such testing be

certified at these laboratories. The Coast Guard may consider third

party testing in a subsequent rulemaking where the public will have an

opportunity to comment.

Section 111.105. Several comments indicated that the obsolete MI

Type cable, referenced in Sec. 111.105-17, paragraph (a), has been

eliminated by the proposed IEEE Std 45 and should also be removed from

these regulations. Additionally, with new technologies in cable jacket

chemistry, these comments suggested that the armor requirements for

hazardous location cables also be removed, as they have been for non-

hazardous areas.

The Coast Guard agrees and subpart 111.105 has been revised

accordingly.

Section 111.105-3. Several comments recommended revising this

section as it allows unarmored cable in hazardous locations.

As indicated above in the discussion of comments for subpart

111.105, the general requirement for armored cable in all hazardous

locations has been removed.

Section 111.105-5. One comment supports the inclusion of API RP 505

as a criteria for system integrity, while another comment stated that

it would be imprudent to consider the adoption of any API RP's because

they are superseded by IEC documents addressing both MODU's and fixed

platforms in a single comprehensive document.

The API RP 505 is in draft form and as such is unavailable to the

Coast Guard for review or to the public for purchase. When the document

is published, the Coast Guard may consider API RP 505 for a subsequent

rulemaking where the public will have an opportunity to comment.

The IEC, in which the U.S. participates, is in the final draft

stages of IEC Publication 1892 (IEC 1892), ``Mobile and Fixed Offshore

Units--Electrical Installations.'' IEC 1892, part 3 addresses hazardous

locations. This document reflects international consensus and will be

considered for inclusion in these regulations in a subsequent

rulemaking.

Section 111.105-11. (1) One comment pointed out that the two

standards referenced in paragraph (a) are not compatible because IEC

79-11 defines two types of IS systems (Ia and Ib), whereas UL 913

defines only one.

The Coast Guard accepts the UL 913 definition or IEC 79-11 (Ia)

only. Paragraph (a) has been revised accordingly.

(2) Several comments recommended removing the option for shielded

cable in paragraph (b)(1) because most shielding may be very thin and

not suitable for safely providing sufficient isolation from non-IS

circuits. Another comment recommended in paragraph (b)(1) removing the

option for metallic armored cable since armoring is for mechanical

protection and not to be substituted for an electromagnetic

interference (EMI) shield.

The purpose of paragraph (b)(1) is to offer options to protect

intrinsically safe circuit cables from induced voltages generated by

magnetic fields of non-intrinsically safe circuit cables. The Coast

Guard agrees that an armored covering is not meant to function as an

EMI shield. However, properly installed and grounded braided armor does

afford some degree of protection depending on intercircuit parameters.

Additionally, if a shielded cable is installed for protection, it is

assumed that its dimensions have passed plan review and that it is

suitable for the service intended. Both options are retained.

Section 111.105-17. (1) One comment suggested clarifying the first

sentence in paragraph (a) so that not all hazardous locations are

required to have through runs of cable.

The intention of paragraph (a) is that all hazardous areas be

fitted with through runs of cable, therefore the requirement remains.

(2) Several comments suggested that paragraph (a) be revised to

require that cable in all hazardous locations be armored.

As indicated above in the discussion of comments for subpart

111.105, the general requirement for armored cable in all hazardous

locations has been removed but the installation of armored cable

remains as an option.

Section 111.105-31. One comment suggested adding a new paragraph

(f)(5) harmonizing Coast Guard and ABS requirements for pump room

ventilation and monitoring.

The Coast Guard recognizes the need for direction on this subject.

However, new material must be presented to the public for comment

before a final rule. The Coast Guard may consider these provisions for

a subsequent rulemaking where the public will have an opportunity to

comment.

Section 111.107-1. One comment recommended removing the word

``and'' in paragraph (c)(1)(i) and adding the word ``or'' since either

standard will provide a comparable level of safety.

This section has been revised accordingly.

Section 112.05-5. One comment recommended modifying paragraph (d)

to allow equipment that supports the emergency power source (e.g., fans

and CO2 bottles).

Paragraph (d) has been revised accordingly.

Section 112.50-1. (1) One comment suggested adding a new paragraph

(l) that requires the generator circuit breaker open upon the shutting

down of the prime mover as required in ABS Rules for Building and

Classing Steel Vessels section 4/5.119.1.

A similar comment was directed towards Sec. 111.12-11, Generator

protection, of this chapter. The requirement established in

Sec. 111.12-11 is applicable to all generators. The equipment described

in Sec. 112.50-1 are special features for emergency generators only.

Therefore the restating of this requirement is unnecessary.

(2) One comment indicated that in paragraph (d) the 45 second

response time is longer than the 30 second response of the standby ship

service generator required for unattended machinery plants in 46 CFR

62.50-30(k)(2).

The 45 second requirement in this section is for emergency

generator sets and is aligned with SOLAS 74, Regulation II-1/42.3.1.2

requirements. The 30 second requirement in 46 CFR part 62 is for a

standby ship service generator in an unattended machinery space. If the

standby ship service generator does not come on line within its

allotted time, the emergency source would power its circuits shortly

thereafter.

Section 112.50-7. One comment indicated that paragraph (c)(3)

appears to have been deleted.

The five asterisks after paragraph (c)(2) indicates that the

remainder of this section is retained. However, paragraph (d) is

removed by the amendatory language of item 169 in the interim rule.

Part 113. One comment pointed out that the title of several

sections of this part use the words ``alarm system'' as a general term

for the ``general emergency alarms and fire alarms.'' It suggested not

using this terminology because it

[[Page 23904]]

typically describes ``machinery alarm systems.''

In this part, the terminology is used with consideration of the

context of each subpart. Wherever in this part the regulations

reference the general emergency alarm system, the words ``general

emergency alarm system'' are used. The more generic term of ``alarm

system'' is used in reference to machinery alarm systems and other

specialized alarms such as engineers' assistance needed, steering

failure, and refrigerated spaces where appropriate.

Section 113.05-7. (1) One comment noted that in paragraph (b) the

reference to IEC 553 is a misprint and should read IEC 533 (entitled

Electromagnetic Compatibility of Electrical and Electronic

Installations in Ships) as stated in Sec. 110.10-1, Incorporation by

reference.

Paragraph (b) has been revised accordingly.

(2) One comment stated that the environmental test requirements of

this section are burdensome if applied to each new piece of equipment

due to advances in technology and the continual development of new

components. The comment suggested creating a self-certification

requirement similar to 46 CFR 62.20-5, Self-certification.

The Coast Guard does not deem self-certification as sufficient for

this equipment. Testing of original and redesigned equipment required

by subchapter Q to be Coast Guard ``approved'' is performed by

independent laboratories accepted by the Commandant. The testing

protocols and their results are strictly reviewed by the Coast Guard or

designated third parties before an approval certificate is issued.

Alarms that are allowed in 46 CFR part 62 to be self-certified must be

designed to meet the environmental standards of 46 CFR 62.25-30,

Environmental design standards, which reference ABS Rules for Building

and Classing Steel Vessels. Subchapter J also references ABS (ABS Rules

for Building and Classing Steel Vessels, table 4/11.1) for

environmental testing requirements.

Section 113.10-7. One comment suggested that the requirement for

connection boxes to meet IEC IP 67 is unnecessarily severe.

In all subparts where the interim rule required connection boxes to

be NEMA 250 Type 6 or 6P or IEC IP 67, the requirement has changed to

NEMA 250 Type 4 or 4X or IEC IP 56 to align the requirement with the

definition of ``watertight.''

Section 113.25-10. One comment suggested that red flashing lights

be used only in conjunction with the general emergency alarm signal and

for no other purpose. This is preferable to the IMO Code on Alarms and

Indicators, which allows the color red to also be used when indicating

the release of fire-extinguishing medium. A standardized color would

allow quick identification and response by personnel.

While the value of this practice is realized, the Coast Guard will

not include specific provisions or requirements on this subject in this

rule without allowing an opportunity for public comment. The term

``flashing red lights'' has been changed to include rotating beacons as

well.

Section 113.25-11. One comment suggested revising the introductory

sentence in Sec. 113.25-11 to read as follows, ``Each contact maker,

where installed, must--''

The Coast Guard determined that the requirements listed in this

section apply to all contact makers, conventional or electronic type

integrated in the public address system, and the addition of the words

``where installed'' does not add to the clarity of the sentence.

Section 113.25-12. One comment recommended in paragraph (a) the use

of air operated alarm signals which may be actuated by a solenoid valve

located outside the hazardous area.

This section does not preclude air operated alarm signals or other

types compatible with the environment in which they are used. Any new

or non-conventional alarm signal will be considered in the plan review

process.

Section 113.30-3. One comment requested clarification of the phrase

``must be independent of the ship's electrical system.'' The ship's

electrical system may be interpreted to mean the ship's AC electrical

system or the ship's DC system with a battery power source.

The power for the emergency means of communication required by this

subpart must not be reliant upon the vessel's normal source or

emergency source of AC or DC power. Acceptable methods of power include

sound-powered phone, telephone systems which are powered by hand

cranked generators which charge capacitor circuits, and individually

battery powered devices.

Section 113.30-5. (1) One comment suggested that in paragraph (a) a

cross-reference to 46 CFR 62.50-20(f)(2) be added.

The cross-reference to 46 CFR 62.50-20 has been added.

(2) One comment recommended editorial revision to paragraph (h)(1)

for clarity.

Paragraph (h)(1) has been revised accordingly.

Section 113.30-25. (1) One comment indicated in paragraph (i) that

cables for safety related circuits should only be permitted to be

routed through high fire risk areas if it is technically impractical to

route them otherwise or if they serve circuits within the high risk

area. In either case, cables should be of the fire resistant type. The

comment stated that decisions in these areas should not be affected by

commercial considerations.

The Coast Guard develops its regulations with the primary

consideration being safety. Any commercial consideration would be

secondary and related to cost savings to the industry through

harmonizing with domestic and international industry standards

resulting in additional options.

Section 111.60-1 requires that accepted marine shipboard cable must

meet the respective flammability tests contained in the referenced or

companion standards. These tests are a validation that the cable is

``flame retardant''; i.e., that the flame is not propagated. IEC 331,

however, measures the ``fire-resisting'' characteristics as noted in

the scope ``as one which will continue to function normally during and

after a prolonged fire.''

As published in the interim rule, paragraph (i) states that cable

runs through high fire risk areas, which includes servicing equipment

within these areas, must meet IEC 331. It is the intent that such

cables not only prevent the proliferation of flame but also maintain

service to the equipment as well.

(2) One comment suggested modifying the last line of paragraph (e)

to read ``an emergency power source'' instead of ``the vessel's

electric system.''

The paragraph has been revised to clarify which vessel's electric

source is intended.

Section 113.43-3. The reference to Secs. 58.25-45 and 111.93-9 is

out-of-date and has been corrected.

Section 113.50-15. One comment noted that, as written, this section

appears to require explosionproof speakers in hazardous locations, for

example, a cargo pump room on a tanker. The comment requests review of

this requirement to determine whether it is excessive.

All systems and enclosures for hazardous locations must be

certified for the particular Class and Division (Zone) in which they

are installed. In the example given, if the speaker system were to be

found intrinsically safe during plan review, then explosionproof

speakers would not be required. Alternatively, if a study did not prove

that the speakers were necessary in that

[[Page 23905]]

location, they would be disallowed under Sec. 111.105-31(f) or, if

proven necessary, they must be explosionproof.

Section 113.50-20. One comment suggested adding additional

requirements applicable to public rooms, alleyways, and stairways to

align the regulations with the IMO Code of Alarms and Indicators.

The Coast Guard may consider additional requirements to align

Sec. 113.50-20 with the IMO Code on Alarms and Indicators in a

subsequent rulemaking where the public will have an opportunity to

comment.

Section 113.70. One comment recommended adding a new subpart that

addresses the installation and operation of gas detection systems. The

comment suggests these systems meet the general requirements of the

International Society for Measurement and Control (ISA) SP12.13 parts I

and II.

The Coast Guard may consider additional requirements for gas

detection systems in a subsequent rulemaking where the public will have

an opportunity to comment.

Section 161.002-1. Components for automatic fire detection systems,

EN54 parts 1 through 11, published by the European Committee for

Standardization (CEN) remain absent from this section because several

of the documents obtained by the Coast Guard were in draft form. The

Coast Guard may consider the finalized documents for a subsequent

rulemaking where the public will have an opportunity to comment.

Incorporation by Reference

The Director of the Federal Register has approved the material in

Secs. 110.10-1 and 161.002-1 for incorporation by reference under 5

U.S.C. 552 and 1 CFR part 51. Copies of the material are available from

the source listed in those sections.

Regulatory Evaluation

This rule 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). A Regulatory Evaluation under paragraph 10e of the

regulatory policies and procedures of DOT is available in the docket

for inspection or copying where indicated under ADDRESSES. A summary of

the Evaluation follows:

Most of the changes to the regulations are either editorial or

update technical specifications to reflect the latest practices.

Although some of these changes will cause minor cost increases for

shipbuilders, others will result in substantial savings. The cost

increases resulting from these rules will be more than offset by the

cost savings, due to relaxations in the rules. The Coast Guard

estimates that the cost of complying with the rule over the next 10

years will total $33,753,392 (in present value); but, this cost will be

more than offset by the estimated net benefits of $73,538,213. This is

a cost-benefit ratio of $1.00 of costs to $2.18 of benefits.

Many of the changes causing cost increases are already current

marine industry practices, such as an increase in the protection of

cable from bilge water.

There are several intangible benefits. Due to the increased use of

national and international standards, certain items will now be more

readily available ``off the shelf'' for marine use. A significant

economic savings will result from the ability of equipment

manufacturers, in many cases, to meet the new performance

specifications instead of the old, prescriptive design standards. Also,

the cost of submitting detailed plans and specifications to the Coast

Guard for approval of certain equipment, such as sound powered

telephones, emergency loudspeaker systems, and navigation lights, will

be eliminated.

No comments were received to the Regulatory Evaluation or its

summary in the preamble to the interim rule.

Small Entities

Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the

Coast Guard considered whether this final rule will have a significant

economic impact on a substantial number of small entities. ``Small

entities'' include small businesses, not-for-profit organizations that

are independently owned and operated and are not dominant in their

fields, and governmental jurisdictions with populations of less than

50,000.

This rule will affect entities that come under Standard Industrial

Code (SIC) categories of 4412 through 4489 (Water Transportation) and

1311 and 1381 (Oil and Gas Extraction), both groups of which are

considered small entities if they have 500 or less employees, and under

SIC category 3731 (Shipbuilding and Repair), which are considered small

entities if they have 1,000 or less employees.

The Coast Guard has taken measures to accommodate the interests of

small entities during the development of this rule. The rule is limited

to vessels that are constructed or undergo major modifications after

September 30, 1996, thereby exempting the existing fleet from having to

conform to these requirements. Furthermore, it is limited to Coast

Guard-inspected commercial vessels, such as oil and chemical tankers,

container ships, large passenger vessels, mobile offshore drilling

units, research vessels, and school ships, which tend to be larger

vessels. It does not apply to uninspected passenger vessels, commercial

fishing vessels, or the overwhelming majority of inspected, small-

passenger vessels.

To reduce the burden on small entities, this rule purges obsolete

and out-of-date regulations and eliminates requirements that create an

unwarranted differential between Coast Guard's regulations and industry

standards. It enhances the flexibility of vessel owners, operators,

manufacturers, and shipbuilders by incorporating, wherever possible,

more options for compliance or by replacing prescriptive requirements

with performance standards.

This rule reduces costs by increasing choices available during the

new construction or major modification of a vessel. As discussed under

the Regulatory Evaluation section in this preamble, this rule will

reduce costs of shipbuilding for all entities, whether large or small.

The Coast Guard estimates that the cost of complying with the rule over

the next 10 years will total $33,753,392 (in present value); but, this

cost will be more than offset by the estimated net benefits of

$73,538,213. This is a cost-benefit ratio of $1.00 of costs to $2.18 of

benefits.

Therefore, the Coast Guard certifies under section 605(b) of the

Regulatory Flexibility Act (5 U.S.C. 601 et seq.) that this final rule

will not have a significant economic impact on a substantial number of

small entities.

Assistance for Small Entities

In accordance with section 213(a) of the Small Business Regulatory

Enforcement Fairness Act of 1996 (Pub. L. 104-121), the Coast Guard

offers to assist small entities in understanding this rule so that they

can better evaluate its effects on them. If your small business or

organization is affected by this rule and you have questions concerning

its provisions or options for compliance, please contact Ms. Laura

Hamman, Office of Design and Engineering Standards, 202-267-2206.

[[Page 23906]]

ensure compliance with the electrical regulations.

Frequency of Response: A response is due each time initial approval

is sought and each time a revision is requested.

Burden Estimate: 60 hours.

Respondents: 6 manufacturers.

Average Burden Hours per Respondent: 10 hours per respondent.

As required by 5 U.S.C. 3507(d), the Coast Guard submitted a copy

of this rule to the Office of Management and Budget (OMB) for its

review of the collection of information. OMB has approved the

collection. The subpart numbers are 110.25 of subchapter J and 161.002

of subchapter Q. The corresponding OMB approval numbers are OMB Control

Number 2115-0115 for subpart 110.25, which expires on August 3, 1999,

and OMB Control Number 2115-0121 for subpart 161.002, which expires

September 30, 1999.

Persons are not required to respond to a collection of information

unless it displays a currently valid OMB control number.

Federalism

The Coast Guard has analyzed this rule under the principles and

criteria contained in Executive Order 12612 and has determined that

this rule does not have sufficient federalism implications to warrant

the preparation of a Federalism Assessment.

Environment

The Coast Guard considered the environmental impact of this rule

and concluded that, under paragraph 2.B.2.e(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 to

the enhancement of vessel safety and, thereby, help to minimize impacts

on the marine environment. A ``Categorical Exclusion Determination'' is

available in the docket for inspection or copying where indicated under

ADDRESSES.

Note to paragraph (d): An alarm contact or indicating device

returned to the main switchboard via a control cable, that allows the

detecting equipment to remain near the transformer or other isolating

device for local troubleshooting, is allowed.

14. Revise Sec. 111.05-27 to read as follows:

Sec. 111.05-27 Grounded neutral alternating current systems.

Grounded neutral and high-impedance grounded neutral alternating

current systems must have a suitably sensitive ground detection system

which indicates current in the ground connection, is able to withstand

the maximum available fault current without damage, and provides

continuous indication of circuit status to ground. A provision must be

included to compare indications under fault conditions with those under

normal conditions.

15. In Sec. 111.05-33, revise the section heading and paragraph (b)

to read as follows:

Sec. 111.05-33 Equipment safety grounding (bonding) conductors.
