# §71.50-29. Hull examination reports.

- (a) If you use only divers for the underwater survey portion of the Alternative Hull Examination (AHE), you must provide the Officer in Charge, Marine Inspection (OCMI), with a written hull examination report. This report must include thickness gauging results, bearing clearances, a copy of the audio and video recordings, and any other information that will help the OCMI evaluate your vessel for a credit hull exam. The third party examiner must sign the report and confirm the validity of its contents.
- (b) If you use an underwater ROV as the predominant means to examine the vessel's underwater hull plating, you must provide the OCMI with a report in the format that is accepted by the OCMI, per [§ 71.50-27(b)](/cfr/46/71.50-27.md?p=b) of this part.
- (c) The OCMI will evaluate the hull examination report and grant a credit hull exam if satisfied with the condition of the vessel. If approved and you exclusively use divers to examine the hull plating, you may receive a credit hull exam up to 36 months. (Underwater examinations are required twice every 5 years). If approved and you use an underwater ROV as the predominant means to examine the underwater hull plating, you may receive a credit hull exam up to 60 months (5 years).
- (d) At least 60 days prior to each scheduled underwater exam, the owner may request a waiver from the OCMI if:
  - (1) A satisfactory exam has been completed within the last three years;
  - (2) The conditions during the last exam allowed at least 80 percent of the bottom surface to be viewed and recorded; and
  - (3) **The results of the last exam indicated that an extended interval is safe and reasonable.**
