§ 126.140

46 CFR Ch. I (10–1–09 Edition)
Drydocking.

(a) Unless one or more extensions are
authorized by the Commandant (CG–
543), each OSV must be placed in drydock or hauled out for examination
twice each 5 years with no interval between examinations exceeding 3 years.
(b) The owner or operator shall notify the cognizant OCMI whenever the
OSV is drydocked for any reason. This
OCMI, upon notification, will determine whether to assign a marine inspector to examine the underwater hull
of the vessel.
(c) The internal structural members
of an OSV must be examined at the
same intervals required for drydocking
by paragraph (a) of this section.
(d) At each drydocking required by
paragraph (a) of this section, for an
OSV of 100 or more gross tons, a
tailshaft survey must be conducted as
required by § 61.20–15 of this chapter.
(e) At each drydocking required by
paragraph (a) of this section, for an
OSV of less than 100 gross tons, the
propeller or tailshaft must be drawn
for examination if the cognizant OCMI
deems drawing it necessary.
(f) Vessels less than 15 years of age
(except wooden hull vessels) that are in
salt water service with a twice in 5
year drydock interval may be considered for an underwater survey instead
of alternate drydock examinations,
provided the vessel is fitted with an effective hull protection system. Vessel
owners or operators must apply to the
Officer in Charge, Marine Inspection
(OCMI), for approval of underwater surveys instead of alternate drydock examinations for each vessel. The application must include the following information:
(1) The procedure to be followed in
carrying out the underwater survey;
(2) The location where the underwater survey will be accomplished;
(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; and
(8) The name and qualifications of
any third party examiner.
(g) Vessels otherwise qualifying
under paragraph (f) 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 the cognizant
District Commander;
(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 OCMI, are submitted to Commandant (CG–543) for
final approval.

When the repairs or alterations have
been made, notice must be given to
this OCMI as soon as practicable.
(b) When emergency repairs or alterations have been made as permitted
under paragraph (a) of this section, the
master, owner, or operator must notify
this OCMI as soon as practicable after
the emergency.
(c) Except as provided by paragraphs
(b) and (e) of this section, drawings of
repairs or alterations must be approved, before work starts, by the cognizant OCMI or, when necessary, by the
Commanding Officer, Marine Safety

§ 126.160 Tests and inspections during
repairs or alterations, or during riveting, welding, burning, or other
hot work.
(a) NFPA 306 must be used as a guide
in conducting the examinations and
issuances of certificates required by
this section.
(b) Until an examination has determined that work can proceed safely, no
riveting, welding, burning, or other hot
work may commence.
(c) Each examination must be conducted as follows:
(1) At any port or site inside the
United States or its territories and
possessions, a marine chemist certified
by the NFPA must make the examination. If the services of such a chemist
are not reasonably available, the cognizant OCMI, upon the recommendation of the contractor and the owner or
operator of the OSV, may authorize another person to make the examination.
If this indicates that a repair or alteration, or hot work, can be undertaken
safely, the person performing the examination shall issue a certificate, setting forth the spaces covered and any
necessary conditions to be met, before
the work starts. These conditions must
include any requirements necessary to
maintain safe conditions in the spaces
covered and must include any necessary further examinations and certificates. In particular the conditions
must include precautions necessary to
eliminate or minimize hazards caused
by protective coatings or by cargo residues.
(2) At any port or site outside the
United States or its territories and
possessions, where the services of a certified marine chemist or other person
authorized by the cognizant OCMI are
not reasonably available, the master,
owner, or operator of the vessel shall

make the examination and a proper
entry in the OSV’s logbook.
(d) The master shall obtain a copy of
each certificate issued by the person
making the examination described in
paragraph (c)(1) of this section. The
master, through and for the persons
under his control, shall maintain safe
conditions aboard the OSV by full observance of each condition to be met,
listed in the certificate issued under
paragraph (c)(1) of this section.
§ 126.170

Carriage of offshore workers.

(a) Offshore workers may be carried
aboard an OSV in compliance with this
subchapter. The maximum number of
offshore workers authorized for carriage will be endorsed on the vessel’s
Certificate of Inspection; but in no case
will the number of offshore workers authorized for carriage exceed 36.
(b) No more than 12 offshore workers
may be carried aboard an OSV certificated under this subchapter when on
an international voyage, unless the
vessel holds a valid passenger-shipsafety certificate (Form CG–968) issued
in compliance with the International
Convention for the Safety of Life at
Sea, 1974, as amended (SOLAS 74/83).
§ 126.180

Carriage of passengers.

No passengers as defined by 46 U.S.C.
2101(21)(B) may be carried aboard an
OSV except in an emergency.

Subpart B—Certificate of
Inspection
§ 126.210

When required.

Except as provided by §§ 126.120 and
126.260, no OSV may be operated without a valid Certificate of Inspection.
§ 126.220

Description.

The Certificate of Inspection issued
to an OSV specifies the vessel, the
route it may travel, the minimum
manning it requires, the minimum fireextinguishing and lifesaving equipment
it must carry, the maximum number of
offshore workers and of total persons it
may carry, the name of its owner and
operator, and such other conditions as
the cognizant OCMI may determine.
