Harvey Energy was built by the Gulf

Coast Shipyard in Gulfport, Mississippi, with careful monitoring by both ABS and the Coast Guard. The Coast Guard recently promulgated policy letters ad- dressing: (1) operations and training of personnel on vessels using natural gas as fuel; and (2) vessels and waterfront facilities conducting LNG marine fuel transfer (bunkering) operations. The

Coast Guard also has been working closely with the IMO in development of an International Code of Safety for Ships
