[Code of Federal Regulations] [Title 46, Volume 7] [Revised as of October 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 46CFR176.620] [Page 214] TITLE 46--SHIPPING CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED) PART 176--INSPECTION AND CERTIFICATION--Table of Contents Subpart F--Hull and Tailshaft Examinations Sec. 176.620 Description of the Alternative Hull Examination (AHE) Program for certain passenger vessels. The Alternative Hull Examination (AHE) Program provides you with an alternative to drydock examination by allowing your vessel's hull to be examined while it remains afloat. If completed using only divers, this program has four steps: the application process, the preliminary examination, the pre-survey meeting, and the hull examination. If a remotely operated vehicle (ROV) is used during the program the preliminary exam step may be omitted. Once you complete these steps, the Officer in Charge, Marine Inspection (OCMI) will evaluate the results and accept the examination as a credit hull exam if the vessel is in satisfactory condition. If divers are exclusively used for the underwater survey portion of the examination process, you may receive credit for a period of time such that subsequent AHEs would be conducted at intervals of twice in every five years, with no more than three years between any two AHEs. If an underwater ROV is used as the predominant method to examine the vessel's underwater hull plating, you may receive credit up to five years. At the end of this period, you may apply for further participation under the AHE Program. Note: The expected hull coverage when using an ROV must be at least 80 percent.
