              under the Federal Register Act. Under the provisions of 44 
              U.S.C. 1507, the contents of the CFR, a special edition of the 
              Federal Register, shall be judicially noticed. The CFR is

              the Federal Register (44 U.S.C. 1510).

          It is prohibited to use NARA's official seal and the stylized Code 
              of Federal Regulations logo on any republication of this 
              material without the express, written permission of the 
              Archivist of the United States or the Archivist's designee. 
              Any person using NARA's official seals and logos in a manner 
              inconsistent with the provisions of 36 CFR part 1200 is 
              subject to the penalties specified in 18 U.S.C. 506, 701, and

                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2005), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

OBSOLETE PROVISIONS

    Provisions that become obsolete before the revision date stated on 
the cover of each volume are not carried. Code users may find the text 
of provisions in effect on a given date in the past by using the 
appropriate numerical list of sections affected. For the period before 
January 1, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate 
volumes. For the period beginning January 1, 2001, a ``List of CFR 
Sections Affected'' is published at the end of each CFR volume.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    Properly approved incorporations by reference in this volume are 
listed in the Finding Aids at the end of this volume.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed in 
the Finding Aids of this volume as an approved incorporation by 
reference, please contact the agency that issued the regulation 
containing that incorporation. If, after contacting the agency, you find 
the material is not available, please notify the Director of the Federal 
Register, National Archives and Records Administration, Washington DC 
20408, or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Statutory 
Authorities and Agency Rules (Table I). A list of CFR titles, chapters, 
and parts and an alphabetical list of agencies publishing in the CFR are 
also included in this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

Sec. 90.05-5  Specific application noted in text.

    (a) At the beginning of the various parts, subparts, and sections, a 
more specific application is generally given for the particular portion 
of the text involved. This application sets forth the types, sizes, or 
services or vessels to which the text pertains, and in many cases limits 
the application of the text to vessels contracted for before or after a 
specific date. As used in this subchapter, the term ``vessels contracted 
for'' includes not only the contracting for the construction of a 
vessel, but also the contracting for a material alteration to a vessel, 
the contracting for the conversion of a vessel to a cargo or 
miscellaneous vessel, and the changing of service or route of a vessel 
if such change increases or modifies the general requirements for the 
vessel or increases the hazards to which it might be subjected.

including the Great Lakes.



Sec. 90.05-10  Application to vessels on an international voyage.

    (a) Except for yachts and fishing vessels and as provided in 
paragraphs (b), (c), and (d) of this section, the regulations in this 
subchapter that apply to a vessel on an ``international voyage'' apply 
to a vessel that--
    (1) Is mechanically propelled and of at least 500 gross tons; and
    (2) Is engaged on a voyage--
    (i) From a country to which the International Convention for Safety 
of Life at Sea, 1974, (SOLAS 74) applies, to a port outside that country 
or the reverse;
    (ii) From any territory, including the Commonwealth of Puerto Rico, 
all possessions of the United States and all lands held by the United 
States under a protectorate or mandate, whose international relations 
are the responsibility of a contracting SOLAS 74 government, or which is 
administered by the United Nations, to a port outside the territory or 
the reverse; or
    (iii) Between the contiguous states of the United States and the 
states of Hawaii or Alaska or between the states of Hawaii and Alaska.
    (b) The regulations that apply to a vessel on an ``international 
voyage'' in this subchapter do not apply to ships engaged on a voyage 
solely on the Great Lakes and the St. Lawrence River as far east as a 
straight line drawn from Cap de Rosiers to West Point, Anticosti Island, 
the 63d Meridian;
    (c) The Commandant or his authorized representative may exempt any 
vessel on an international voyage from the requirements of this 
subchapter if the vessel--
    (1) Makes a single international voyage in exceptional 
circumstances; and
    (2) Meets safety requirements prescribed for the voyage by the 
Commandant.
    (d) The Commandant or his authorized representative may exempt any 
vessel from the construction requirements of this subchapter if the 
vessel does not proceed more than 20 nautical miles from the nearest 
land in the course of its voyage.

proceed on voyages on the high seas or ocean are

[[Page 14]]

subject to inspection and certification as seagoing barges.
    (b) In applying the laws and regulations to manned seagoing barges, 
one criterion for invocation of safety standards is the description of 
seagoing barges by relative size in gross tons. When it is determined by 
the Commandant that the gross register tonnage for a particular manned 
seagoing barge, which is attained by exemptions, reductions, or other 
devices in the basic gross tonnage formulation, will circumvent or be 
incompatible with the application of specific safety requirements in the 
regulations in this subchapter for a manned seagoing barge of such 
physical size, the Commandant shall prescribe the regulations to be made 
applicable to such seagoing barge. When the Commandant determines that 
the gross register tonnage is not a valid criterion for the invocation 
of safety requirements based on relative size, the parties involved will 
be informed of the determination and of the regulations applicable to 
such manner seagoing barges, and before being permitted to operate such 
seagoing barges, compliance therewith shall be required. Endorsements or 
notations on the seagoing barge's certificate of inspection may be made 
as appropriate.

subject to inspection and certification shall be operated without a 
valid certificate of inspection.



Sec. 91.01-5  Posting.

    (a) On vessels of over 25 gross tons, the original certificate of 
inspection shall, in general, be framed under glass and posted in a 
conspicuous place where it will be most likely to be observed. On 
vessels not over 25 gross tons, and on other vessels such as barges, 
where the framing of the certificate under glass would be impracticable, 
the original certificate of inspection shall be kept on board to be 
shown on demand.



Sec. 91.01-10  Period of validity for a Certificate of Inspection.

    (a) Certificates of inspection will be issued for a period of 5 
years. Application may be made by the master, owner, or agent for 
inspection and issuance of a new certificate of inspection at any time 
during the period of validity of the current certificate.
    (b) Certificates of inspection may be revoked or suspended by the 
Coast Guard where such process is authorized by law. This may occur if 
the vessel does not meet the requirements of law or regulations in this 
chapter or if there is a failure to maintain the safety requirements 
requisite to the issuance of a certificate of inspection.
    (c)(1) In the case of the following vessels, modification of the 
period of validity of the certificate of inspection will be permitted as 
set forth in this paragraph:
    (i) Nonself-propelled vessels of 100 gross tons and over proceeding 
on the high seas or ocean for the sole purpose of changing place of 
employment.

[[Page 20]]

    (ii) Nonself-propelled vessels of 100 gross tons and over making 
rare or infrequent voyages on the high seas or ocean and returning to 
the port of departure.
    (2) The certificate of inspection may be issued for a specific 
period of time to cover a described situation or for one voyage only but 
in no case to exceed 5 years. The certificate of inspection will include 
the conditions under which the vessel must operate. Unless the vessel is 
in compliance with this Subchapter insofar as it applies to seagoing 
barges of 100 gross tons and over, such vessel shall not carry any 
person on board while underway, and the certificate of inspection will 
be endorsed as an unmanned seagoing barge.

    (a) Nothing in this subpart shall prevent a vessel upon a regularly 
established line from a port in the United States to a port of a foreign 
country not contiguous to the United States whose certificate of 
inspection expires at sea or while said vessel is in a foreign port or a 
port of Hawaii from lawfully completing her voyage without the valid 
certificate of inspection or temporary certificate required by this 
subpart: Provided, That the certificate of inspection did not expire 
within 15 days after the vessel left the last port of the United States, 
and that the voyage shall be completed within 30 days after the 
expiration of the certificate of inspection.



Sec. 91.01-25  Emergency carriage of more than 16 persons in addition 
to the crew on vessels not engaged in international voyages.

    (a) When a District Commander finds that an emergency situation

    (3) The method to be used to accurately determine the diver location 
relative to the hull.
    (4) The means that will be provided for examining through-hull 
fittings.
    (5) The means that will be provided for taking shaft bearing 
clearances.
    (6) The condition of the vessel, including the anticipated draft of 
the vessel at the time of the survey.
    (7) A description of the hull protection system.
    (e) Vessels otherwise qualifying under paragraph (d) of this 
section, that are 15 years of age or older, may be considered for 
continued participation in or entry into the underwater survey program 
on a case-by-case basis if--
    (1) Before the vessel's next scheduled drydocking, the owner or 
operator submits a request for participation or continued participation 
to Commandant (G-MOC);
    (2) During the vessel's next drydocking after the request is 
submitted, no appreciable hull deterioration is indicated as a result of 
a complete set of hull gaugings; and
    (3) The results of the hull gauging and the results of the Coast 
Guard drydock examination together with the recommendation of the 
Officer in Charge, Marine Inspection, are submitted to Commandant (G-
MOC) for final approval.
    (f) Each vessel which has not met with the applicable examination 
schedules in paragraphs (a) through (e) of this section because it is on 
a voyage, must undergo the required examinations upon completion of the 
voyage.
    (g) The Commandant (G-MOC) may authorize extensions to the 
examination intervals specified in paragraph (a) of this section.

    (a) As the relative location of shipyards, design offices, and Coast 
Guard offices vary throughout the country,

[[Page 34]]

no specific routing will be required in the submittal of plans. In 
general, one of the following procedures would apply, but in a 
particular case, if a more expeditious procedure can be used, there will 
be no objection to its adoption.
    (1) The plans may be submitted to the Officer in Charge, Marine 
Inspection, in the district in which the vessel is to be built. This 
procedure will be most expeditious in the case of those offices where 
personnel and facilities are available for examination and approval of 
the plans locally.
    (2) The plans may be submitted directly to the Commandant (G-MSE), 
U.S. Coast Guard, Washington, DC 20593-0001. In this case, the plans 
will be returned directly to the submitter, with a copy of the action 
being forwarded to the interested Officer in Charge, Marine Inspection.
    (3) The plans may be submitted directly to Commanding Officer, U.S. 
Coast Guard Marine Safety Center, 400 Seventh St., SW., Washington, DC 
20590-0001.
    (4) In the case of classed vessels, upon specific request by the 
submitter, the American Bureau of Shipping will arrange to forward the 
necessary plans to the Coast Guard indicating its action thereon. In 
this case, the plans will be returned as noted in paragraph (a)(2) of 
this section.

meet the following requirements:
    (a) The field of vision from the navigation bridge, whether the 
vessel is in a laden or unladen condition, must be such that:
    (1) From the conning position, the view of the sea surface is not 
obscured forward of the bow by more than the lesser of two ship lengths 
or 500 meters (1,640 feet) from dead ahead to 10 degrees on either side 
of the vessel. Within this arc of visibility any blind sector caused by 
cargo, cargo gear, or other permanent obstruction must not exceed 5 
degrees.
    (2) From the conning position, the horizontal field of vision 
extends over an arc from at least 22.5 degrees abaft the beam on one 
side of the vessel, through dead ahead, to at least 22.5 degrees abaft 
the beam on the other side of the vessel. Blind sectors forward of the 
beam caused by cargo, cargo gear, or other permanent obstruction must 
not exceed 10 degrees each, nor total more than 20 degrees, including 
any blind sector within the arc of visibility described in paragraph 
(a)(1) of this section.
    (3) From each bridge wing, the field of vision extends over an arc 
from at least 45 degrees on the opposite bow, through dead ahead, to at 
least dead astern.
    (4) From the main steering position, the field of vision extends 
over and arc from dead ahead to at least 60 degrees on either side of 
the vessel.
    (5) From each bridge wing, the respective side of the vessel is 
visible forward and aft.
    (b) Windows fitted on the navigation bridge must be arranged so 
that:
    (1) Framing between windows is kept to a minimum and is not 
installed immediately in front of any work station.

Sec. 92.10-1  Application.

    (a) The provisions of this subpart, with the exception of Sec. 
92.10-90, shall apply to all vessels contracted for on or after November 
19, 1952. Vessels contracted for prior to November 19, 1952, shall meet 
the requirements of Sec. 92.10-90.



Sec. 92.10-5  Two means required.

    (a) There shall be at least two means of escape from all general 
areas accessible to the passengers, if carried, or where the crew may be 
quartered or normally employed. At least one of these two means of 
escape shall be independent of watertight doors.



Sec. 92.10-10  Location.

    (a) The two means of escape shall be as remote as practicable so as 
to minimize the possibility of one incident blocking both escapes.



Sec. 92.10-15  Vertical ladders not accepted.

    (a) Vertical ladders and deck scuttles shall not in general be 
considered satisfactory as one of the required means of escape. However, 
where it is demonstrated that the installation of a stairway would be 
impracticable, a vertical ladder may be used as the second means of 
escape.



Sec. 92.10-20  No means for locking doors.

    (a) No means shall be provided for locking doors giving access to 
either of the two required means of escape, except that crash doors or 
locking devices, capable of being easily forced in an emergency, may be 
employed provided a permanent and conspicuous notice to this effect is 
attached to both sides of the door. This paragraph shall not apply to 
outside doors to deckhouses where such doors are locked by key only and 
such key is under the control of one of the vessel's officers.



Sec. 92.10-25  Stairway size.

    (a) Stairways shall be of sufficient width having in mind the number 
of persons having access to such stairs for escape purposes.
    (b) Vessels contracted for on or after January 1, 1959, shall meet 
the requirements of this paragraph. Special consideration for relief may 
be given in the case of small vessels if it is shown to be unreasonable 
or impracticable to meet the requirements.
    (1) All interior stairways, other than those within the machinery 
spaces or cargo holds, shall have a minimum width of 28 inches. The 
angle of inclination with the horizontal of such stairways shall not 
exceed 50 degrees.



Sec. 92.10-30  Dead end corridors.

    (a) Dead end corridors, or the equivalent, more than 40 feet in 
length shall not be permitted.



Sec. 92.10-35  Public spaces.

Sec. 95.10-1  Application.

    (a) The provisions of this subpart, with the exception of Sec. 
95.10-90, shall apply to all fire main installations contracted for on 
or after May 26, 1965. Installations contracted for prior to May 26, 
1965, shall meet the requirements of Sec. 95.10-90.



Sec. 95.10-5  Fire pumps.

    (a) Vessels shall be equipped with independently driven fire pumps 
in accordance with Table 95.10-5(a).

\1\ On vessels of 65 feet in length or less, \3/4\-inch hose of good
  commercial grade together with a commercial garden hose nozzle may be
  used. The pump may be hand operated and the length of hose shall be
  sufficient to assure coverage of all parts of the vessel.
\2\ 75 feet of 1\1/2\-inch hose and \5/8\-inch nozzle may be used where
  specified by Sec. 95.10-10(b) for interior locations and 50 feet of
  1\1/2\-inch hose may be used in exterior locations on vessels in other
  than ocean or coastwise service.

    (b) On vessels of 1,000 gross tons and over on an international 
voyage, each required fire pump, while delivering water thru the fire 
main system at a pressure corresponding to that required by paragraph 
(c) of this section, shall have a minimum capacity of at least two-
thirds of that required for an independent bilge pump. However, in no 
case shall the capacity of each fire pump be less than that otherwise 
required by this section.
    (c) Each pump shall be capable of delivering water simultaneously 
from the two highest outlets at a Pitot tube pressure of approximately 
50 p.s.i. Where 1\1/2\-inch hose is permitted in lieu of 2\1/2\-inch 
hose by footnote 2 of Table 95.10-5(a), the pump capacity shall be 
determined on the same basis as if 2\1/2\-inch hose had been permitted. 
Where \3/4\-inch hose is permitted by Table 95.10-5(a), the Pitot tube 
pressure need be only 35 p.s.i.
    (d) Fire pumps shall be fitted on the discharge side with relief 
valves set to relieve at 25 p.s.i. in excess of the pressure necessary 
to maintain the requirements of paragraph (c) of this section or 125 
p.s.i., whichever is greater. Relief valves may be omitted if the pumps, 
operating under shut-off conditions, are not capable of developing a 
pressure exceeding this amount.
    (e) Fire pumps shall be fitted with a pressure gage on the discharge 
side of the pumps.
    (f) Fire pumps may be used for other purposes provided at least one 
of the required pumps is kept available for use on the fire system at 
all times. In no case shall a pump having connection to an oil line be 
used as a fire pump. Branch lines connected to the fire main for 
purposes other than fire and deck wash shall be so arranged that 
adequate water can be made continuously available for firefighting 
purposes.
    (g) The total area of the pipes leading from a pump shall not be 
less than the discharge area of the pump.
    (h) On vessels with oil fired boilers, either main or auxiliary, or 
with internal combustion propulsion machinery, where 2 fire pumps are 
required, they shall be located in separate spaces, and the arrangement 
of pumps, sea connections, and sources of power shall be such as to 
insure that a fire in any one space will not put all of the fire pumps 
out of operation. However, where it is shown to the satisfaction of the 
Commandant that it is unreasonable or impracticable to meet this 
requirement due to the size or arrangement of the

[[Page 49]]

vessel, or for other reasons, the installation of a total flooding 
carbon dioxide system may be accepted as an alternate method of 
extinguishing any fire which would affect the powering and operation of 
at least one of the required fire pumps.

Sec. 95.10-10  Fire hydrants and hose.

    (a) The size of fire hydrants, hose, and nozzles and the length of 
hose required shall be as noted in Table 95.10-5(a).
    (b) In lieu of the 2\1/2\-inch hose and hydrants specified in Table 
95.10-5(a), on vessels over 1,500 gross tons, the hydrants in interior 
locations may have siamese connections for 1\1/2\-inch hose. In these 
cases the hose shall be 75 feet in length, and only one hose will be 
required at each fire station; however, if all such stations can be 
satisfactorily served with 50-foot lengths, 50-foot hose may be used.
    (c) On vessels of 500 gross tons and over there must be at least one 
shore connection to the fire main available to each side of the vessel 
in an accessible location. Suitable cut-out valves and check valves must 
be provided. Suitable adapters also must be provided for furnishing the 
vessel's shore connections with couplings mating those on the shore fire 
lines. Vessels of 500 gross tons and over on an international voyage, 
must be provided with at least one international shore connection 
complying with ASTM F 1121 (incorporated by reference, see Sec. 95.01-
2). Facilities must be available enabling an international connection to 
be used on either side of the vessel.
    (d) Fire hydrants shall be of sufficient number and so located that 
any part of the vessel, other than main machinery spaces, accessible to 
persons on board while the vessel is being navigated and all cargo holds 
may be reached with at least 2 streams of water from separate outlets, 
at least one of which shall be from a single length of hose. In main 
machinery spaces, all portions of such spaces shall be capable of being 
reached by at least 2 streams of water, each of which shall be from a 
single length of hose from separate outlets; however, this requirement 
need not apply to shaft alleys containing no assigned space for the 
stowage of combustibles. Fire hydrants shall be numbered as required by 
Sec. 97.37-15 of this subchapter.
    (e) All parts of the fire main located on exposed decks shall either 
be protected against freezing or be fitted with cut-out valves and drain 
valves so that the entire exposed parts of such piping may be shut off 
and drained in freezing weather. Except when closed to prevent freezing, 
such valves shall be sealed open.
    (f) The outlet at the fire hydrant shall be limited to any position 
from the horizontal to the vertical pointing downward, so that the hose 
will lead horizontally or downward to minimize the possibility of 
kinking.
    (g) Each fire hydrant must have at least one length of firehose, a 
spanner, and a hose rack or other device for stowing the hose.
    (h) Fire hose shall be connected to the outlets at all times. 
However, on open decks where no protection is afforded to the hose in 
heavy weather, or where the hose may be liable to damage from the 
handling of cargo, the hose may be temporarily removed from the hydrant 
and stowed in an accessible nearby location.
    (i) Each firehose on each hydrant must have a combination solid 
stream and water spray firehose nozzle approved under subpart 162.027 of 
this chapter. Firehose nozzles previously approved under subpart 162.027 
of this chapter may be retained so long as they are maintained in good 
condition to the satisfaction of the Officer in Charge, Marine 
Inspection.
    (j) In each propulsion machinery space containing an oil fired 
boiler, internal combustion machinery, or oil fuel unit on a vessel on 
an international voyage or of 1000 gross tons or more, each firehose 
having a combination nozzle previously approved under subpart 162.027 of 
this chapter must have a low-velocity water spray applicator that is 
also previously approved under subpart 162.027 of this chapter. The 
length of the applicator must be less than 1.8 meters (6 feet).
    (k) Fixed brackets, hooks, or other means for stowing an applicator 
must

[[Page 50]]

be next to each fire hydrant that has an applicator under paragraph (j) 
of this section.
    (l) Firehose shall not be used for any other purpose than fire 
extinguishing, drills, and testing.
    (m) Fire hydrants, nozzles, and other fittings shall have threads to 
accommodate the hose connections noted in paragraph (l) of this section.
    (n) Firehose and couplings must be as follows:
    (1) Fire station hydrant connections shall be brass, bronze, or 
other equivalent metal. Couplings shall either:
    (i) Use National Standard fire hose coupling threads for the 1\1/2\ 
inch (38 millimeter) and 2\1/2\ inch (64 millimeter) hose sizes, i.e., 9 
threads per inch for 1\1/2\ inch hose, and 7\1/2\ threads per inch for 
2\1/2\ inch hose; or
    (ii) Be a uniform design for each hose diameter throughout the 
vessel.
    (2) Where 19 millimeters (\3/4\ inch) hose is permitted by table 
95.10-5(a), the hose and couplings shall be of good commercial grade.
    (3) Each section of firehose must be lined commercial firehose that 
conforms to Underwriters' Laboratories, Inc. Standard 19 or Federal 
Specification ZZ-H-451E. Hose that bears the label of Underwriters' 
Laboratories, Inc. as lined firehose is accepted as conforming to this 
requirement.

requirements of subchapter F (Marine Engineering) of this chapter.
    (b) All distribution cut-off valves shall be marked as required by 
Sec. 97.37-10 of this subchapter.
    (c) For vessels on an international voyage, the diameter of the fire 
main shall be sufficient for the effective distribution of the maximum 
required discharge from two fire pumps operating simultaneously. This 
requirement is in addition to Sec. 95.10-5(c). The discharge of this 
quantity of water through hoses and nozzles at a sufficient number of 
adjacent hydrants shall be at a minimum Pitot tube pressure of 
approximately 50 pounds per square inch.

       Subpart 95.15_Carbon Dioxide Extinguishing Systems, Details



Sec. 95.15-1  Application.

    (a) Where a carbon dioxide extinguishing system is installed, the 
provisions of this subpart, with the exception of Sec. 95.15-90, shall 
apply to all installations contracted for on or after November 19, 1952. 
Installations contracted for prior to November 19, 1952, shall meet the 
requirements of Sec. 95.15-90.
    (b) The requirements of this subpart are based on a ``high pressure 
system,'' i.e., one in which the carbon dioxide is stored in liquid form 
at atmospheric temperature. Details for ``low pressure systems,'' i. e., 
those in which the carbon dioxide is stored in liquid form at a 
continuously controlled low temperature, may be specifically approved by 
the Commandant where it is demonstrated that a comparable degree of 
safety and fire extinguishing ability is achieved.



Sec. 95.15-5  Quantity, pipe sizes, and discharge rates.

    (a) General. The amount of carbon dioxide required for each space 
shall be as determined by paragraphs (b) through (d) of this section.
    (b) Total available supply. A separate supply of carbon dioxide need 
not be provided for each space protected. The total available supply 
shall be at least sufficient for the space requiring the greatest 
amount.
    (c) Cargo spaces. (1) The number of pounds of carbon dioxide 
required for each space shall be equal to the gross volume of the space 
in cubic feet divided by 30.
    (2) Although separate piping shall be led to each cargo hold and 
'tween deck, for the purpose of determining the amount of carbon dioxide 
required, a cargo compartment will be considered as the space between 
watertight or firescreen bulkheads and from the tank top or lowest deck 
to the deck head of the uppermost space on which cargo may be carried. 
If a trunk extends beyond such deck, the trunk volume shall be included. 
Tonnage openings shall be considered as sealed for this purpose.
    (3) Branch lines to the various cargo holds and 'tween decks shall 
not be less than \3/4\-inch standard pipe size.
    (4) No specific discharge rate need be applied to such systems.
    (d) Machinery spaces, paint lockers, tanks, and similar spaces. (1) 
Except as provided in paragraph (d)(3) of this section, the number of 
pounds of carbon dioxide required for each space shall be equal to the 
gross volume of the space divided by the appropriate factor noted in 
Table 95.15-5(d)(1). If fuel can drain from the compartment being 
protected to an adjacent compartment, or if the compartments are not 
entirely separate, the requirements for both compartments shall be used 
to determine the amount of carbon dioxide to be provided. The carbon 
dioxide shall be arranged to discharge into both such compartments 
simultaneously.

    (2) For the purpose of the requirements of this paragraph, the 
volume of the machinery space shall be taken as exclusive of the normal 
machinery casing unless the boiler, internal combustion machinery, or 
fuel oil installation extend into such space, in which case the volume 
shall be taken to the top of the casing or the next material reduction 
in casing area, whichever is lower. For installations contracted for on 
or after October 1, 1959, ``normal machinery casing'' and ``material 
reduction in casing area'' shall be defined as follows:
    (i) By ``normal machinery casing'' shall be meant a casing the area 
of which is not more than 40 percent of the maximum area of the 
machinery space.
    (ii) By ``material reduction in casing area'' shall be meant a 
reduction to at least 40 percent of the casing area.
    (3) For vessels on an international voyage contracted for on or 
after May 26, 1965, the amount of carbon dioxide required for a space 
containing propulsion boilers or internal combustion propulsion 
machinery shall be as given by paragraphs (d) (1) and (2) of this 
section or by dividing the entire volume, including the casing, by a 
factor of 25, whichever is the larger.
    (4) Branch lines to the various spaces shall be as noted in Table 
95.15-5(d)(4).

systems for tanks, which are of more than 300 pounds of carbon dioxide, 
shall be fitted with an approved delayed discharge so arranged that the 
alarm will be sounded for at least 20 seconds before the carbon dioxide 
is released into the space. Such systems of not more than 300 pounds of 
carbon dioxide shall also have a similar delayed discharge, except for 
those systems for tanks and for spaces which have a suitable horizontal 
escape. This paragraph shall be applicable only to systems installed on 
or after July 1, 1957.
    (g) All distribution valves and controls shall be of an approved 
type. All controls shall be suitably protected.
    (h) Complete but simple instructions for the operation of the 
systems must be located in a conspicuous place at or near all pull 
boxes, stop valve controls and in the CO2 cylinder storage 
room. On systems in which the CO2 cylinders are not within 
the protected space, these instructions must also include a schematic 
diagram of the system and instructions detailing alternate methods of 
discharging the system should the manual release or stop valve controls 
fail to operate. Each control valve to branch lines must be marked to 
indicate the related space served.
    (i) If the space or enclosure containing the carbon dioxide supply 
or controls is to be locked, a key to the space or enclosure shall be in 
a break-glass-type box conspicuously located adjacent to the opening.

a time and place which he or she approves. No written application is 
required.
    (c) The scope of the annual inspection is the same as the inspection 
for certification as specified in Sec. 107.231, except Sec. 107.231(x) 
and (y), but in less detail unless the cognizant OCMI finds deficiencies 
or determines that a major change has occurred since the last 
inspection. If deficiencies are found or a major change to the MODU has 
occurred, the OCMI will conduct an inspection more detailed in scope to 
ensure that the MODU is in satisfactory condition and fit for the 
service for which it is intended. If your MODU passes the annual 
inspection, the OCMI will endorse your current Certificate of 
Inspection.
    (d) If the annual inspection reveals deficiencies in your MODU's 
maintenance, you must make any or all repairs or improvements within the 
time period specified by the OCMI.
    (e) Nothing in this subpart limits the marine inspector from 
conducting such tests or inspections he or she deems necessary to be 
assured of the vessel's seaworthiness.

Regulation

[[Page 117]]

2(d) of part A, chapter I in the International Convention for Safety of 
Life at Sea, 1974. (SOLAS 74), which is: ``a voyage from a country to 
which the present Convention applies to a port outside such country, or 
conversely. The Coast Guard has interpreted this definition to include 
the following:
    (1) A voyage from a country to which SOLAS 1974 applies, to a port 
outside that country or the reverse;
    (2) A voyage from any territory, including the Commonwealth of 
Puerto Rico, all possesssions of the United States, and all lands held

outside that territory or the reverse;

The Coast Guard has interpreted this definition to not include a ``Great 
Lakes voyage'' which means a voyage solely on the Great Lakes of North 
America and the St. Lawrence River west of a straight line drawn from 
Capedes Rosiers to West Point, Anticosti Island and, on the north side 
of Anticosti Island, the 63rd Meridian.

A, Chapter I, of SOLAS 74 which states the following:

    a. A ship which is not normally engaged on international voyages but 
which, in exceptional circumstances, is required to undertake a single 
international voyage may be exempted by the Administration from any of 
the requirements of the present Regulations provided that it complies 
with safety requirements which are adequate in the opinion of the 
Administration for the voyage which is to be undertaken by the ship.
    b. The Administration may exempt any ship which embodies features of 
a novel kind from any of the provisions of Chapters II-1, II-2, III and 
IV of these Regulations the application of which might seriously impede 
research into the development of such features and their incorporation 
in ships engaged on international voyages. Any such

[[Page 118]]

ship shall, however, comply with safety requirements which, in the 
opinion of that Administration, are adequate for the service for which 
it is intended and are such as to ensure the overall safety of the ship 
and which are acceptable to the Governments of the States to be visited 
by the ship. The Administration which allows any such exemption shall 
communicate to the Organization particulars of same and the reasons 
therefor which the Organization shall circulate to the Contracting 
Governments for their information.

    (c) The Commandant (G-MOC) may exempt a self-propelled unit of at 
least 500 gross tons on an international voyage from the requirements of 
Chapter III (Lifesaving Appliances, &C.) of SOLAS 74 if the unit meets 
the conditions of Regulation 2 of chapter III which states in part:

    The Administration may, if it considers that the sheltered nature 
and conditions of the voyage are such as to render the application of 
any specific requirements of this chapter unreasonable or unnecessary, 
exempt from those requirements individual ships or classes of ships 
which, in the course of their voyage, do not proceed more than 20 miles 
from the nearest land.

    (d) The Commandant (G-MOC) may exempt a unit from the requirements 
of Chapters II-1 (Construction--Subdivision and stability, machinery and 
electrical installations) or II-2 (Construction--Fire protection, fire 
detection and fire extinction) of SOLAS 74 if the unit meets the 
conditions of Regulation 1-4 of Part A Chapter II-1 or Regulation 1-4.1 
of Part A Chapter II-2, respectively, of SOLAS 74 which state the 
following: The Administration of a State may, if it considers that the 
sheltered nature and conditions of the voyage are such as to render the 
application of any specific requirements of this chapter unreasonable or 
unnecessary, exempt from those requirements individual ships or classes 
of ships entitled to fly the flag of the State which, in the course of 
their voyage, do not proceed more than 20 miles from the nearest land.
    (e) An Exemption Certificate is in force for the period of validity 
of the certificate to which it refers.

considerations which are unique to the hull and structural designs, 
industrial equipment and operating procedures incorporated in drilling 
vessels. To provide appropriate and adequate standards, the Coast Guard 
with the assistance of the National Offshore Operations Advisory 
Committee, and following the provisions of the Administrative Procedures 
Act, developed Subchapter IA, Regulations for Mobile Offshore Drilling 
Units, 46 CFR Parts 107-109 and amendments to 46 CFR Subchapters ``F'', 
Marine Engineering Regulations, and ``J'', Electrical Engineering 
Regulations. These regulations, published in Federal Register (43 FR 
56788 December 4, 1978) will apply to all units contracted for on or 
after the effective date of the regulations.
    3. Discussion. a. This NVIC elaborates the ``grandfather 
provisions'' of 46 CFR 107.211 and 107.215 in applying Subchapter IA to 
the approximately 150 existing ocean-going U.S. flag mobile offshore 
drilling units. ``Existing'' Mobile Offshore Drilling Units are those 
vessels which have been contracted for before the effective date of the 
regulations including:
    (1) Units in Service.
    (2) Units under construction.
    (3) Units contracted for which are to be constructed and delivered 
prior to January 1, 1981.
    b. Existing uncertificated mobile drilling units of which there are 
approximately 92 of the bottom bearing configuration, i.e., jack-up and 
submersible types, have not previously been required to comply with 
vessel inspection regulations. Some units have met the load line 
requirements of Subchapter ``E'' for International Voyages. Many of the 
older units are not classed by a classification society. Bottom bearing 
units operating on the Outer Continental Shelf of United States have 
been required to meet the safety requirements of 33 CFR Subchapter ``N'' 
as artificial islands. On January 3, 1979, existing bottom bearing units 
are subject to the ``grandfather provisions'' in Sec. 107.211(c) of 
Subchapter IA.
    c. Existing certificated mobile offshore drilling units, for the 
purposes of this NVIC, are column-stabilized and ship-shape types of 
which approximately 58 are currently certificated, or have made 
application for an original Certificate of Inspection or intend to make 
application for an original inspection for certification under 46 CFR 
Subchapter ``I'' on the basis of the unit being contracted for prior to 
the effective date of the new regulations. These units may continue to 
meet the structural, equipment, material and arrangement standards which 
were applicable to the hull, engineering, electrical and industrial 
systems when the units were contracted for. In addition they must meet 
the provisions of d.(1), d.(4)(d), d.(7)(b), d.(8), d.(9), d.(10)(b), 
d.(11) and d.(12) of paragraph 3 of this NVC in accordance with Sec. 
107.215(c)(2) of Subchapter IA.
    d. Inspection Provisions for Existing Uncertificated Units. The 
intent of the ``grandfather'' provisions of this NVIC for existing 
uncertificated units is to ascertain through inspection that the 
material condition of the unit and its equipment meet reasonable levels 
of safety. To this end, the following determinations will be made:
     The design, construction and arrangements of the 
hull, machinery electrical and industrial systems do not reveal 
manifestly unsafe aspects.
     There is no excessive deterioration of the hull 
structure or equipment foundations.

[[Page 177]]

     There are no intrinsic fire or explosion hazards.
     There are no personnel hazards such as unguarded 
moving machinery, potential electrical shock conditions or lack of 
handrails.
     The unit is seaworthy and exhibits satisfactory 
stability.
    (1) General. (a) Repairs and minor alterations to hull structure or 
equipment may be made to the same standards as the original 
installation. However, new installations or major alterations which 
affect vessel or personnel safety shall meet the applicable standards of 
Subchapter IA.
    (b) Existing items of safety equipment not meeting the applicable 
specifications or requirements set forth in Subchapter IA may be 
continued in service as long as they are maintained in good working 
order to the satisfaction of the OCMI. Such safety equipment and 
installations requiring extensive repairs shall be replaced and shall 
meet the applicable specifications and requirements of Subchapter IA.
    (c) The OCMI has discretion to accept alternatives or equivalents 
which meet the established standards, and to give special consideration 
to departures from the regulations when it can be shown that special 
circumstances warrant such departures.
    (2) Plan Submittal. (a) For units not classed by the American Bureau 
of Shipping or other recognized classification society, (see 46 CFR 
108.109) the OCMI must have sufficient plans and information submitted 
to him which will describe such things as the unit's size, construction, 
configuration, arrangement of tanks, decks and spaces; and the machinery 
and electrical installation. In addition, the OCMI may require submittal 
of any additional data he considers necessary in order to proceed with 
the original inspections.
    (b) For units classed by the American Bureau of Shipping or other 
recognized classification society, the plans and information described 
in Subchapter IA Sec. 107.305 (a), (b), (v), and (ii) and a general 
description of the machinery and electrical installation shall be 
submitted to the OCMI for information. The OCMI may accept continued 
classification as proof of structural, mechanical, and electrical 
sufficiency. However, the OCMI may require additional plans and 
information if necessary.
    (3) Hull Structure. (a) No structural changes will be required 
unless manifestly unsafe conditions exist.
    (b) Existing uncertificated units must be drydocked or have a 
special examination in lieu of drydocking as required by 46 CFR, 107-
261.
    (c) Achievement of one compartment subdivision is not required where 
extensive modification of the original design would be necessary; 
however, watertight integrity of the hull and structural boundaries must 
be maintained. Bulkheads and decks designed to be watertight must be 
maintained as such where they are penetrated by pipes, electrical cable, 
reach rods, ventilation systems, etc.
    (4) Stability. (a) The stability of each existing unit will be 
reviewed by the Coast Guard. The plans indicated in 46 CFR Subchapter IA 
Sec. 107.305(q) through (u-l) must be submitted to the cognizant OCMI 
or Merchant Marine Technical Office.
    (b) Lightship data from a Coast Guard witnessed and approved 
stability test is required for each existing, uncertificated unit. 
Alternatively other evidence of lightship values will be considered on a 
case by case basis.
    (c) In general, compliance with the intact stability standards of 46 
CFR Subchapter IA, Sec. Sec. 108.303 through 108.309 is required. Where 
existing units were designed to a lesser standard of stability than that 
specified in Sec. Sec. 108.303 through 108.309, some relaxation based 
on proven past performance may be granted at the discretion of the OCMI 
and limiting conditions, if any, set forth in the operating manual. In 
no case will the minimum wind speed for adequate stability be reduced 
below 50 knots.
    (d) An operating manual shall be prepared for each unit. Each 
operating manual must contain the information indicated in 46 CFR 
Subchapter IA, Sec. 109.121(d) and be submitted to the cognizant OCMI 
or Merchant Marine Technical Office for review.
    (5) Load Line. (a) All units are required to obtain and maintain a 
valid Load Line Certificate. The structure and stability of the unit 
must be proven adequate for the voyages and areas of operation intended.
    (b) The American Bureau of Shipping or other recognized 
classification society will issue Load Line Certificates and conduct 
initial and annual load line surveys. Coast Guard and the American 
Bureau of Shipping inspections may be conducted simultaneously, but it 
is the owner's responsibility to arrange coordinated inspection 
schedules.
    (c) The structural review conducted by the American Bureau of 
Shipping or other recognized classification society for load line 
assignment may be accepted by the Coast Guard as proof of structural 
adequacy of the hull.
    (d) The stability review must be completed prior to issuance of a 
Load Line Certificate. The Coast Guard will inform the American Bureau 
of Shipping or other recognized classification society of the results of 
the stability review, and will indicate any stability limitations to be 
placed on the Load Line Certificate.
    (e) Freeboard calculations for self-elevating units with barge type 
hulls will be made in accordance with 46 CFR, Part 42. The bow height 
requirements of 46 CFR 42.20-70 may be relaxed to approximately 33% of 
the normal requirement for barge shapes

[[Page 178]]

moving at speeds less than 6 knots. No relaxation of the addition to 
freeboard for deficiency in sheer is allowed. The freeboard for units 
other than self-elevating units with barge type hulls will be based upon 
compliance with the intact and damage stability standards applicable at 
the time the unit was contracted for.
    (f) All units delivered after the date of this NVIC regardless of 
contract date, must obtain a Load Line Certificate as soon as 
operationally feasible.
    (6) Route and Operating Area Limitations. (a) Units classed by the 
American Bureau of Shipping or other recognized classification society 
for ocean service generally will be certificated by the Coast Guard for 
ocean routes.
    (b) Unclassed units which have proven structural and stability 
adequacy by continued safe operation in a specific geographic area, such 
as the Gulf of Mexico, will be limited by the Certificate of Inspection 
and Load Line Certificate to that area. To qualify for an unlimited 
oceans route, such a unit must be reviewed for adequacy of the structure 
and stability by the Coast Guard and meet the Load Line requirements of 
d. (5) above.
    (c) Any unit which intends to move or operate outside the 
geographical area indicated on the Certificate of Inspection must 
receive prior approval from the OCMI.
    (7) Fire Protection. (a) Structural fire protection. All units must 
meet the provisions of Sec. 108.123, Insulation of Combustible 
Materials and Sec. 108.127, Storage Lockers for Combustibles. All 
existing interior stairways which are open at each end must be enclosed 
at one level. On units where wood was utilized in the construction of 
accommodation spaces, each space must be equipped with a smoke or heat 
detector either battery powered or operating on the AC power supply. All 
detectors must have the Underwriters Laboratories, Inc., label (UL) or 
the Factory Mutual Laboratories (FM) label.
    (b) Fire Extinguishing Systems. Systems and equipment must be 
provided which will meet or be equivalent to the applicable 
specifications and provisions required by Subchapter IA. Installed fire 
extinguishing systems, which provide equivalent or greater protection 
than systems required by Subpart E, Subchapter IA may be continued in 
use as long as they are in good material condition and will function as 
designed. Where practicable, existing washdown systems may be utilized 
as the firemain. Where wood was utilized in the construction of 
accommodation spaces, the applicable requirements of 46 CFR Subchapter 
IA, Table 108.495(a) should be doubled.
    (8) Lifesaving Equipment. (a) Each unit must have lifesaving 
equipment (lifeboats and davit launched liferafts) for 200 percent of 
the total persons allowed on board. Except for submersible type units, 
the installation of lifeboats for 100 percent of the persons (on board) 
is required in accordance with 46 CFR 108.503 of Subchapter IA. 
Consideration will be given to those units where existing arrangement 
and structure do not provide sufficient room for installation of the 
lifeboats or where the added weight of the lifeboats, davits and winches 
will materially reduce the variable load capacity of the unit. In such 
cases, davit launched inflatable liferafts with a combined personnel 
capacity of the required lifeboats, and a rescue boat approved by the 
OCMI may be acceptable equivalents. Submersible type units may 
substitute Coast Guard approved throw over type inflatable liferafts and 
an approved rescue boat for the required lifeboats.
    (b) For the second part of the total 200 percent primary lifesaving 
requirement, lifeboats installed in accordance with 33 CFR, Subchapter 
``N'' Part 144 or Coast Guard approved life floats may be retained as 
provided for in 3.d(1)(b) of this Circular. They will be considered 
collectively with the Coast Guard approved liferafts for calculating the 
amount of equipment to provide for 100 percent of personnel on board.
    (c) Adequate access to all lifesaving equipment must be provided.
    (9) Cranes. (a) Plan approval will not normally be required of any 
crane which conforms to the specifications of the manufacturer as 
originally installed. A rated load test as described in Sec. 107.260 of 
Subchapter IA will be required unless the crane has been load tested 
while under certification by an approved certifying authority as 
provided for in 46 CFR 107.258. Prior to the rated load test, the crane 
should be identified by manufacturer and model number to determine that 
the correct load rating chart is being used. The owner must submit to 
the OCMI details and calculations of any alterations to a crane which 
were accomplished without manufacturer's documentation in order to 
verify the rated load of the crane.
    (10) Electrical. (a) Multiple power sources do not require an 
emergency generator; however, storage batteries or approved relay-
controlled battery operated lanterns are required to be installed for 
the emergency lighting system and provide 12 hours of lighting.
    (b) Electrical equipment installed in Class I, division 1 and 2 
locations, as defined in Subchapter IA, Sec. 108.170 must be of a 
suitable type and in good material condition.
    (11) Unfired Pressure Vessels. (a) Unfired pressure vessels built 
and stamped in accordance with Section VIII of the ASME Code may be 
continued in service as long as they remain in satisfactory condition. 
At the original and subsequent inspections for certification, ASME Code 
pressure vessels must be tested and examined in accordance with the 
requirements in 46 CFR 61.10-5.

[[Page 179]]

    (b) Unfired pressure vessels which cannot be identified as being 
constructed to any recognized standard may be continued in service 
provided that no obvious defects are noted. These pressure vessels shall 
be hydrostatically tested to one and one half times the working 
pressure. For pressure vessels that can not be reasonably 
hydrostatically tested, nondestructive testing may be used to verify the 
pressure vessels condition for continued serviceability. These pressure 
vessels will then be stamped with a Coast Guard identification number 
and periodically tested and examined in accordance with the requirements 
in 46 CFR 61.10-5.
    (12) Marine Sanitation Devices. (a) All units must meet the 
provisions of 33 CFR Part 159, Coast Guard Marine Sanitation Devices 
Regulations. The discharge requirements are compatible with the OCS 
Orders of the U.S. Geological Survey.
    4. Action. a. The owner of each existing certificated unit must 
provide the cognizant OCMI a proposed plan to accomplish the 
requirements in paragraph 3. c. of this NVIC within 60 days from the 
effective date of the regulations. Most items should be approved at the 
unit's next inspection for certification; however, where major equipment 
installations are concerned, the owner may be allowed up to two years to 
comply with the requirements from the time the OCMI completes his 
assessment of the proposals.
    b. Application for Original Inspection for Certification. Not later 
than sixty days from January 3, 1979, application for original 
inspection for certification of all existing uncertificated units, shall 
be submitted to the appropriate OCMI. The plans or descriptive data 
specified in paragraph 3.d(2) of this NVIC along with a proposed plan to 
bring the unit into compliance should, if possible, be submitted with 
the application for inspection. If not feasible to assemble all required 
information in this time frame, an estimated date of submittal shall be 
indicated on the application. Arrangements should be made to commence 
the original inspection for certification with due consideration for the 
unit's operating situation.
    c. To the extent possible the same inspection team will conduct the 
inspection of all existing uncertificated units in a geographical area. 
It may be advantageous to conduct the original inspection in conjunction 
with an impending special or periodic survey, drydocking or availability 
period. Units under construction will receive primary consideration by 
the OCMI for the allocation of time and personnel so that any problems 
can be identified while the unit is in the most advantageous situation 
to apply corrections.
    d. The variety of designs and arrangements presented by existing 
uninspected MODU's makes it impractical to prescribe detailed standards 
for all existing units. The procedures followed to implement this NVC 
must provide the necessary flexibility. Items which must be taken into 
consideration in applying this NVIC are listed below. Categorizing units 
into groups to which the same items apply will be of value during the 
inspection process. These items are:
     Type
     Builder
     Model
     Date build
     Classed by ABS or other classification society
     Load Line assignment
     Operating history (including geographical areas)
     Present location
    e. Issuance of the Original Certificate of Inspection. The intent of 
the original inspection of existing uncertificated units is to identify 
and commence correction of any unsafe conditions and/or equipment 
deficiencies and to issue the unit an original Certificate of 
Inspection. A reasonable period of time will be permitted to correct 
minor deficiencies. Those items directly affecting personnel safety and 
health will require immediate attention to correct the unsafe condition. 
Extensive deficiencies, such as those involving structural aspects or 
equipment may require up to two years to remedy. Additional times may be 
allowed if repair facilities are not available to coastal areas adjacent 
to the unit's area of operation. Where manifestly unsafe conditions are 
found, the OCMI may require that the unit discontinue operations until 
such conditions are corrected. If the owner or operator feels aggrieved 
by the decision of the OCMI, the appeals procedures of 46 CFR 2.01-70 
are applicable.
    f. Questions concerning this NVIC should be referred to the 
Commandant (G-MOC).

 Subpart 111.05_Equipment Ground, Ground Detection, and Grounded Systems



Sec. 111.05-1  Purpose.

    This subpart contains requirements for the grounding of electric 
systems, circuits, and equipment.
    Note: Circuits are grounded to limit excessive voltage from 
lightning, transient surges, and unintentional contact with higher 
voltage lines, and to limit the voltage to ground during normal 
operation. Conductive materials enclosing electric conductors and

Sec. 111.10-1  Definitions.

    As used in this Subpart:
    (a) Ships's service loads mean electrical equipment for all 
auxiliary services necessary for maintaining the vessel in a normal, 
operational and habitable condition. Ship's service loads include, but 
are not limited to, all safety, lighting, ventilation, navigational, 
communications, habitability, and propulsion auxiliary loads. Electrical 
propulsion motor, bow thruster motor, cargo transfer, drilling, cargo 
refrigeration for other than Class 5.2 organic peroxides and Class 4.1 
self-reactive substances, and other industrial type loads are not 
included.
    (b) Drilling loads means all loads associated exclusively with the 
drilling operation including power to the drill table, mud system, and 
positioning equipment.

28276, June 4, 1996; 62 FR 23907, May 1, 1997]



Sec. 111.10-3  Two generating sources.

    In addition to the emergency power sources required under part 112 
of this chapter, each self-propelled vessel and each mobile offshore 
drilling unit must have at least two electric generating sources.

[CGD 94-108, 61 FR 28276, June 4, 1996]



Sec. 111.10-4  Power requirements, generating sources.

    (a) The aggregate capacity of the electric ship's service generating 
sources required in Sec. 111.10-3 must be sufficient for the ship's 
service loads.
    (b) With the ship's service generating source of the largest 
capacity stopped, the combined capacity of the remaining electric ship's 
service generating source or sources must be sufficient to supply those 
services necessary to provide normal operational conditions of 
propulsion and safety, and minimum comfortable conditions of 
habitability. Habitability services include cooking, heating, air 
conditioning (where installed), domestic refrigeration, mechanical 
ventilation, sanitation, and fresh water.
    (c) The capacity of the ship's service generating sources must be 
sufficient for supplying the ship's service loads without the use of a 
generating source which is dependent upon the speed or direction of the 
main propelling engines or shafting.
    (d) Operating generators must provide a continuous and uninterrupted 
source of power for the ship's service load under normal operational 
conditions. Any vessel speed change or throttle movement must not cause 
a ship's service load power interruption.
    (e) Vessels with electric propulsion that have two or more constant-
voltage generators which supply both ship's service and propulsion power 
do not need additional ship's service generators provided that with any 
one propulsion/ship's service generator out of service the capacity of 
the remaining generator(s) is sufficient for the electrical loads 
necessary to provide normal operational conditions of propulsion and 
safety, and minimum comfortable conditions of habitability.
    (f) A generator driven by a main propulsion unit (such as a shaft 
generator) which is capable of providing electrical power continuously, 
regardless of the speed and direction of the propulsion shaft, may be 
considered one of the ship's service generating sets required by Sec. 
111.10-3. A main-engine-dependent generator which is not capable of 
providing continuous electrical power may be utilized as a supplemental 
generator provided that a required ship's service generator or 
generators having sufficient capacity to supply the ship's service loads 
can be automatically brought on line prior to the main-engine-dependent 
generator tripping off-line due to a change in the speed or direction of 
the main propulsion unit.

Sec. 111.10-5  Multiple energy sources.

    Failure of any single generating set energy source such as a boiler, 
diesel, gas turbine, or steam turbine must not cause all generating sets 
required in Sec. 111.10-3 to be inoperable.

[[Page 218]]



Sec. 111.10-7  Dead ship.

    (a) The generating plant of each self-propelled vessel must provide 
the electrical services necessary to start the main propulsion plant 
from a dead ship condition.
    (b) If the emergency generator is used for part or all of the 
electric power necessary to start the main propulsion plant from a dead 
ship condition, the emergency generator must be capable of providing 
power to all emergency lighting, emergency internal communications 
systems, and fire detection and alarm systems in addition to the power 
utilized for starting the main propulsion plant. Additional requirements 
are in Sec. 112.05-3(c) of this chapter.

Sec. 111.10-9  Ship's service supply transformers; two required.

    If transformers are used to supply the ship's service distribution 
system required by this subpart for ships and mobile offshore drilling 
units, there must be at least two installed, independent power 
transformers. With the largest transformer out of service, the capacity 
of the remaining units must be sufficient to supply the ship service 
loads.

    Note to Sec. 111.10-9: A ship's service supply system would consist 
of transformers, overcurrent protection devices, and cables, and would 
normally be located in the system between a medium voltage bus and a low 
voltage ship's service switchboard.

to open the electric circuit if the current reaches a value that will 
cause an excessive or dangerous temperature in the conductor or 
conductor insulation. A grounded conductor is protected from overcurrent 
if a protective device of a suitable rating or setting is in each 
ungrounded conductor of the same circuit.
    (b) Overcurrent protection of conductors. Each conductor must be 
protected in accordance with its current carrying capacity, except a 
conductor for the following circuits which must meet the following

device not designed to open a short circuit, must not be used for 
protection of a conductor against overcurrent due to a short circuit or 
ground, except in a motor circuit as described in Article 430 of the 
National Electrical Code or in IEC 92-202.
    (f) Ungrounded conductors. A fuse or overcurrent trip unit of a 
circuit breaker must be in each ungrounded conductor. A branch switch or 
circuit breaker must open all conductors of the circuit, except grounded 
conductors.
    (g) Grounded conductor. An overcurrent device must not be in a 
permanently grounded conductor, except:
    (1) An overcurrent device that simultaneously opens all conductors 
of the circuit, unless prohibited by Sec. 111.05-17 for the bus-tie 
feeder connecting the emergency and main switchboards; and
    (2) For motor-running protection described in Article 430 of the

[[Page 229]]

    (3) If the overcurrent device that protects the larger conductors 
also protects the smaller conductors, an overcurrent device is not 
required at the supply to the smaller conductors.
    (4) If the overcurrent device protecting the primary side of a 
single phase transformer (two wire with single-voltage secondary) also 
protects the conductors connected to the secondary side, as determined 
by multiplying the current-carrying capacity of the secondary conductor 
by the secondary to primary transformer voltage ratio, and this

Sec. 111.70-5  Heater circuits.

    (a) If an enclosure for a motor, master switch, or other equipment 
has an electric heater inside the enclosure that is energized from a 
separate circuit, the heater circuit must be disconnected from its 
source of potential by a disconnect device independent of the enclosure 
containing the heater. The heater disconnecting device must be adjacent 
to the equipment disconnecting device. A fixed sign, warning the 
operator to open both devices, must be on the enclosure of the equipment 
disconnect device, except as in paragraph (b) of this section.
    (b) If the location of the enclosure for a motor, master switch, or 
other equipment for deck machinery is remote from the motor and 
controller disconnect device, a sign must be fixed to the enclosure if 
the disconnect arrangement required by paragraph (a) of this section is 
not used. The sign must warn the operator of the presence of two sources 
of potential within the enclosure and show the location of the heater 
circuit disconnect device.
    (c) Electric heaters installed within motor controllers and 
energized from a separate circuit must be disconnected

[[Page 236]]

in the same manner as required by paragraph (a) of this section or by 
Sec. 111.70-7(d).

28282, June 4, 1996]



Sec. 111.70-7  Remote control, interlock, and indicator circuits.

    (a) Overcurrent protection. A conductor of a control, interlock, or 
indicator circuit of a motor controller must be protected against 
overcurrent unless:
    (1) The conductor is wholly within the controller enclosure;
    (2) The rating or setting of the branch circuit overcurrent device 
is not more than 300 percent of the current-carrying capacity of the 
control, interlock, or indicator circuit conductor;
    (3) There is an overcurrent device in each side of the line that has 
a rating or setting of not more than 300 percent of the current-carrying 
capacity of the control, electrical interlock, or indicator circuit 
conductor, except if under operating conditions there is no appreciable 
difference in potential between the external conductors, overcurrent 
protection need only be at the supply of that side of the line; or
    (4) The opening of the control, interlock, or indicator circuit 
creates a hazard.
    Note: For overcurrent protection of steering gear control and 
indicator circuits, see Subpart 111.93 of this chapter.
    (b) Accidental ground. The controller must be designed to prevent an 
accidental ground in a remote control circuit from causing the stop 
switches to fail to operate or causing the motor to start.
    (c) Source of potential. The potential for a control, interlock, or 
indicator circuit must be derived from the load side of the motor and 
controller disconnect device, except if the control functions require 
circuits that must be common to two or more controllers, the switching 
arrangement in paragraph (d) of this section must be met.
    (d) Switching. In the design of a control, interlock, or indicator 
circuit, all practicable steps must be taken to eliminate all but one 
source of power in an enclosure. If the control functions make it 
impracticable to energize a control interlock or indicator circuit from 
the load side of a motor and controller disconnect device and the 
voltage of the control, interlock, or indicator circuit is more than 24 
volts, there must be one of the following alternative methods of 
switching:
    (1) Each conductor of a control, interlock, or indicator circuit 
must be disconnected from all sources of potential by a disconnect 
device independent of the motor and controller disconnect device. The 
two independent devices must be adjacent to each other, and a fixed 
sign, warning the operator to open both devices to disconnect completely 
the motor and controller, must be on the exterior of the door of the 
main disconnect device.
    (2) Each conductor of a control, interlock, or indicator circuit 
must be disconnected from all sources of power by a disconnect device 
actuated by the opening of the controller door, or the power must first 
be disconnected to allow opening of the door. The disconnect device and 
its connections, including each terminal block for terminating the 
vessel's wiring, must have no electrically uninsulated or unshielded 
surface. When this type of disconnect device is used for vital auxiliary 
circuits, a nameplate must be affixed to the vital auxiliary motor 
controller door that warns that opening the door will trip a vital 
auxiliary off-line.

   Subpart 112.01_Definitions of Emergency Lighting and Power Systems



Sec. 112.01-1  Purpose.

    The purpose of this subpart is to define types of emergency lighting 
and power systems.



Sec. 112.01-5  Manual emergency lighting and power system.

    A manual emergency lighting and power system is one in which a 
single manual operation, such as the manual operation of a switch from 
an ``off'' to an ``on'' position, is necessary to cause the emergency 
power source to supply power to the emergency loads.



Sec. 112.01-10  Automatic emergency lighting and power system.

    An automatic emergency lighting and power system is one in which a 
reduction in potential from the ship's service power and lighting plant 
causes the emergency power source to supply power to the emergency 
loads.



Sec. 112.01-15  Temporary emergency power source.

    A temporary emergency power source is one of limited capacity that 
carries, for a short time, selected emergency loads while an emergency 
power source of larger capacity is being started.



Sec. 112.01-20  Final emergency power source.

    A final emergency power source is one that functions after the 
temporary emergency power source is disconnected.



                         Subpart 112.05_General



Sec. 112.05-1  Purpose.

    (a) The purpose of this part is to ensure a dependable, independent, 
and dedicated emergency power source with sufficient capacity to supply 
those services that are necessary for the safety of the passengers, 
crew, and other persons in an emergency and those additional loads that 
may be authorized under paragraph (c) of this section.
    (b) No load may be powered from an emergency power source, except:
    (1) A load required by this part to be powered from the emergency 
power source;
    (2) A bus-tie to the main switchboard that meets Sec. 112.05-3; and
    (3) Emergency loads that may be necessary to maintain or restore the 
propulsion plant, such as control systems, controllable pitch 
propellers, hydraulic pumps, control air compressors, and machinery 
necessary for dead-ship start-up.
    (c) Other loads may be authorized by the Commanding Officer, Marine 
Safety Center (MSC), to be connected to the emergency source of power to 
provide an increased level of safety in recognition of a unique vessel 
mission or configuration. When these loads are authorized, the emergency 
power source must--
    (1) Be sized to supply these loads using a unity (1.0) service 
factor; or
    (2) Be provided with automatic load shedding that removes these 
loads and operates before the emergency generator trips due to overload. 
The automatic load shedding circuit breakers must be manually reset.

28286, June 4, 1996; 61 FR 36787, July 12, 1996]

[[Page 254]]



Sec. 112.05-3  Main-emergency bus-tie.

    Each bus-tie between a main switchboard and an emergency switchboard 
must:
    (a) Disconnect automatically upon loss of potential at the emergency 
switchboard;
    (b) Be arranged to prevent parallel operation of an emergency power 
source with any other source of electric power, except for interlock 
systems for momentary transfer of loads; and
    (c) If arranged for feedback operation, open automatically upon 
overload of the emergency power source before the emergency power source 
is tripped off the line from the overload.



Sec. 112.05-5  Emergency power source.

    (a) The emergency power source must meet table 112.05-5(a) and have 
the capacity to supply all loads that are simultaneously connected to 
it, except a load on a bus-tie to the main switchboard or non-required 
loads that are connected in accordance with Sec. 112.05-1(c).
