of Drydocking (UWILD).

§ 167.15–30 Drydock examination, internal structural examination, and
underwater survey intervals.
(a) Except as provided for in paragraphs (b) through (e) of this section,
each vessel must undergo drydock and
internal structural examinations as
follows:
(1) If your vessel operates in saltwater, it must undergo two drydock examinations and two internal structural
examinations within any 5-year period
unless it has been approved to undergo
an underwater survey (UWILD) under
§ 167.15–33 of this part. No more than
three years may elapse between any
two examinations.
(2) If your vessel operated in fresh
water at least 50 percent of the time
since your last drydocking, it must undergo a dry dock and internal structural examination at intervals not to
exceed 5 years unless it has been approved to undergo an underwater survey (UWILD) under § 167.15–33 of this
part.
(b) Vessels with wooden hulls must
undergo two drydock and two internal
structural examinations within any
five year period regardless of the type
of water in which they operate. No
more than three years may elapse between any two examinations.
(c) If, during an internal structural
examination damage or deterioration
to the hull plating or structural members is discovered, the Officer in
Charge, Marine Inspection, may require the vessel to be drydocked or otherwise taken out of service to further
assess the extent of the damage and to
effect permanent repairs.
(d) Each vessel which has not met
with the applicable examination sched-

(a) The Officer in Charge, Marine Inspection (OCMI), may approve an underwater survey instead of a drydock
examination at alternating intervals if

(3) Fitted with an effective hull protection system; and
(4) Described in 46 CFR 167.15–30(a)(1)

age, you must submit an application
for an underwater survey to the OCMI

next required drydock examination.
The application must include—
(1) The procedure for carrying out
the underwater survey;
(2) The time and place of the underwater survey;
(3) The method used to accurately determine the diver’s or remotely operated vehicle’s (ROV) location relative
to the hull;
(4) The means for examining all
through-hull
fittings
and
appurtenances;
(5) The means for taking shaft bearing clearances;
(6) The condition of the vessel, including the anticipated draft of the
vessel at the time of survey;
(7) A description of the hull protection system; and
(8) The name and qualifications of
any third party examiner.

older, the District Commander, may
approve an underwater survey instead
of a drydock examination at alternating intervals. You must submit an

(2) Your application includes the information in paragraphs (b)(1) through
(b)(8) of this section; and
(3) During the vessel’s drydock examination, preceding the underwater survey, a complete set of hull gaugings
was taken and they indicated that the

deterioration.
(d) After the drydock examination required in paragraph (c)(3) of this section, the Officer in Charge, Marine Inspection submits a recommendation for
future underwater surveys, the results
of the hull gauging, and the results of
the Coast Guards’ drydock examination results to the cognizant District
Commander for review.

§ 167.15–40 Integral fuel oil tank examinations—T/ALL.
(a) Each fuel oil tank with at least
one side integral to the vessel’s hull
and located within the hull (‘‘integral
fuel oil tank’’) is subject to inspection
as provided in this section. The owner
or operator of the vessel shall have the
tanks cleaned out and gas freed as necessary to permit internal examination
of the tank or tanks designated by the
marine inspector. The owner or operator shall arrange for an examination
of the fuel tanks of each vessel during
an internal structural examination at
intervals not to exceed five years.
(b) Integral non-double-bottom fuel
oil tanks need not be cleaned out and
internally examined if the marine inspector is able to determine by external examination that the general condition of the tanks is satisfactory.
(c) Double-bottom fuel oil tanks on
vessels less than 10 years of age need
not be cleaned out and internally examined if the marine inspector is able
to determine by external examination
that the general condition of the tanks
is satisfactory.
(d) Double-bottom fuel oil tanks on
vessels 10 years of age or older but less
than 15 years of age need not be

oil tank, and by external examination
of all other double-bottom fuel oil
tanks on the vessel, that the general
condition of the tanks is satisfactory.
(e) All double-bottom fuel oil tanks
on vessels 15 years of age or older need
not be cleaned out and internally examined if the marine inspector is able
to determine by internal examination
of at least one forward, one amidships,

made to the vessel’s hull.
(c) Each barge that holds a Load Line
Certificate must have a plan showing
the barge’s scantlings. The plan need
not be maintained on board the barge
but must be made available to the
Coast Guard marine inspector whenever the barge undergoes a drydock examination, internal structural examination, underwater survey, or whenever repairs are made to the barge’s
hull.
