46 CFR 115.650 - Alternative Hull Examination (AHE) Program options: Divers or underwater ROV.
To complete your underwater survey, you may use divers or an underwater remotely operated vehicle (ROV).
(a) If you use divers to conduct the underwater survey, you must -
(1) Locate the vessel so the divers can work safely under the vessel's keel and around both sides. The water velocity must be safe for dive operations;
(2) Provide permanent hull markings, a temporary grid system of wires or cables spaced not more than 10 feet apart and tagged at one-foot intervals, or any other acoustic or electronic positioning system approved by the OCMI to identify the diver's location with respect to the hull, within one foot of accuracy;
(3) Take ultrasonic thickness gaugings at a minimum of 5 points on each plate, evenly spaced;
(4) Take hull plating thickness gaugings along transverse belts at the bow, stern, and midships, as a minimum. Plating thickness gaugings must also be taken along a longitudinal belt at the wind and water strake. Individual gaugings along the transverse and longitudinal belts must be spaced no more than 3 feet apart;
(5) Ensure the third party examiner observes the entire underwater examination process;
(6) Record the entire underwater survey with audio and video recording equipment and ensure that communications between divers and the third party examiner are recorded; and
(7) Use appropriate equipment, such as a clear box, if underwater visibility is poor, to provide the camera with a clear view of the hull.
(b) You may use an underwater ROV to conduct the underwater survey. The underwater ROV operating team, survey process and equipment, quality assurance methods, and the content and format of the survey report must be accepted by the Officer in Charge, Marine Inspection (OCMI) prior to conducting the survey. If you choose this option, you must -
(1) Locate the vessel to ensure that the underwater ROV can operate effectively under the vessel's keel and around both sides;
(2) Employ divers to examine any sections of the hull and appurtenances that the underwater ROV cannot access or is otherwise unable to evaluate; and
(3) If the OCMI determines that the data obtained by the ROV, including non-destructive testing results, readability of the results, and positioning standards, will not integrate into the data obtained by the divers, then a third party examiner must be present during the divers portion of the examination.

GPO FDSys XML | Text type regulations.gov FR Doc. 2012-12334 RIN 1625-AB44 USCG-2006-24797 DEPARTMENT OF HOMELAND SECURITY, Coast Guard Final rule. This final rule is effective July 9, 2012. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register on July 9, 2012. 46 CFR Parts 25, 27, 28, 31, 34, 35, 62, 71, 76, 78, 91, 95, 97, 107, 108, 112, 115, 118, 119, 122, 131, 132, 147, 162, 167, 169, 176, 181, 182, 185, 189, 190, 193, 194, and 196 The Coast Guard is amending the current regulations for fire suppression systems on several classes of commercial vessels. The amendments clarify that approved alternatives to carbon dioxide systems may be used to protect some spaces on these vessels, and set general requirements for alternative systems. Additionally, certain new carbon dioxide systems must be equipped with lockout valves and odorizing units to protect persons after a carbon dioxide discharge. By requiring these features on carbon dioxide systems and by making a wider range of fire suppression systems available, the regulations advance the Coast Guard's strategic goals of promoting marine safety and maritime mobility.
