§ 176.660 Continued participation in
the Alternative Hull Examination
(AHE) Program.
(a) To continue to participate in the
AHE Program, vessel operators must
conduct an annual hull condition assessment. At a minimum, vessel operators must conduct an internal examination and take random hull gaugings
internally during the hull condition assessment, unless waived by the Officer
in Charge, Marine Inspection (OCMI). If
the annual hull assessment reveals significant damage or corrosion, where
temporary repairs have been made, or
where other critical areas of concern
have been identified, the OCMI may require an expanded examination to include an underwater hull examination
using divers. If an underwater examination is required, the examination
must focus on areas at higher risk of
damage or corrosion and must include
a representative sampling of hull
gaugings.
(b) If an underwater survey is required for the annual hull condition assessment, the OCMI may require the
presence of a third party examiner and
a written hull examination report must
be submitted to the OCMI. This report
must include thickness gauging results, a copy of the audio and video recordings and any other information
that will help the OCMI evaluate your
vessel for continued participation in
the AHE program. The third party examiner must sign the report and confirm the validity of its contents.
(c) You must submit your preventive
maintenance reports or checklists on
an annual basis to the OCMI. These reports or checklists must conform to
the plans you submitted in your application under § 176.630 of this part,
which the OCMI approved.
(d) Prior to each scheduled annual
hull condition assessment—
(1) The owner may submit to the
OCMI a plan for conducting the assessment, or a request for a waiver of this
requirement, no fewer than 30 days before the scheduled assessment; and
(2) The OCMI may reduce the scope
or extend the interval of the assessment if the operational, casualty, and
deficiency history of the vessel, along

with a recommendation of the vessel’s
master, indicates that it is warranted.

(c) The owner or managing operator
of each vessel that holds a Load Line
Certificate shall make plans showing
