wreier-aviles on DSK3TPTVN1PROD with CFR

§ 107.401

Purpose and definition.

(a) The International Convention for
Safety of Life at Sea, 1974, requires one
or more of the certificates described in
this subpart to be carried on self-propelled vessels of 500 gross tons or over
engaged in international voyages. This
subpart prescribes rules for the
issuance of these certificates to mobile
offshore drilling units.
(b) ‘‘International voyage’’ has the
same meaning as stated in Regulation
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 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 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, Anti-

§ 107.405 Safety Equipment Certificate.
(a) A self-propelled unit of at least
500 gross tons that engages in international voyages is issued a safety
equipment certificate if the inspector
issues it a certificate of inspection
under § 107.211 or § 107.215 and it meets
chapter 3 of the International Convention for Safety of Life at Sea, 1974.
(b) A Safety Equipment Certificate
expires 60 months after the date of
issue.
[CGD 73–251, 43 FR 56802, Dec. 4, 1978, as
amended by CGD 90–008, 55 FR 30662, July 26,
1990; USCG 1999–4976, 65 FR 6504, Feb. 9, 2000]

§ 107.409 Safety Construction Certificate.
(a) Application for a Safety Construction Certificate is made by indicating
in the space provided on the Application for Inspection Form CG–3752
whether the American Bureau of Shipping or the Coast Guard is to issue the
certificate.
(b) The American Bureau of Shipping
or the Coast Guard may issue a selfpropelled unit of at least 500 gross tons
that engages on international voyages
a Safety Construction Certificate if the
unit meets the requirements in Regulation 12 (a)(ii), Chapter I of the International Convention for Safety of Life
at Sea, 1974.
(c) A Safety Construction Certificate
expires 60 months after the date of
issue.
(d) If a unit fails to meet the requirements in Regulation 12(a)(ii), the Coast
Guard may—
(1) Suspend an unexpired Safety Construction Certificate; and
(2) Revoke an unexpired Safety Construction Certificate.

(b) The Commandant (CG–543) may
exempt a self-propelled unit of at least
500 gross tons on an international voyage from any of the requirements in
the International Convention for Safety of Life at Sea, 1974 (SOLAS 74) if the
unit meets the conditions of Regulation 4 of Part 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
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 (CG–543) 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 (CG–543) may
exempt a unit from the requirements of
Chapters II–1 (Construction—Subdivi-

sion 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.

APPENDIX A TO PART 109—NAVIGATION
AND VESSEL INSPECTION CIRCULAR
NO. 4–78—INSPECTION AND CERTIFICATION OF EXISTING MOBILE OFFSHORE DRILLING UNITS
1. Purpose. To promulgate instructions for
the inspection and certification of existing
mobile offshore drilling units. This NVIC is
also being published as appendix A of 46 CFR
Subchapter IA.
2. Background. Mobile Offshore Drilling
Units are recognized internationally through
the Intergovernmental Maritime Consultative Organization as being a ‘‘special purpose ship’’ designed and operated to carry
out an industrial function at sea. Contemporary U.S. Vessel regulations in Title 46
CFR do not adequately cover the safety 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., jackup 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

46 CFR Ch. I (10–1–11 Edition)

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 § 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 § 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.
• 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 es-

tablished 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 § 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
§ 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,
§§ 108.303 through 108.309 is required. Where
existing units were designed to a lesser
standard of stability than that specified in
§§ 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, § 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
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
§ 108.123, Insulation of Combustible Materials
and § 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 § 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 relaycontrolled 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, § 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.
(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 re-

quirements 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 (CG–543).
