Abstract:

This report describes a limited system safety analysis carried out on a commercial vessel. The purpose of conducting the study was to 1 develop a set of inspection criteria derived from a system safety study, 2 demonstrate the application of system safety analysis methodology to a commercial vessel, and 3 identifydefine needed modifications to VIIS as currently being developed for the Coast Guard. The safety analysis was limited to a study of fireexplosion hazards in the vessels cargocargo transfer system. The vessel studied was a 38,000 ton special products carrier hauling gasoline, other petrochemicals, and industrial chemicals in a cargo system consisting of 27 tanks and 21 pumps. Three types of analyses were conducted preliminary hazards, logic diagram, and hazard mode and effect. Findings were based on study of documentation and plans for the vessel plus two on-board inspections, one of which included a six-day voyage. The commercial vessel environment proved entirely amenable to system safety analysis procedures. Although no unexpected or unusual hazards were identified, it was found feasible and reasonable to construct a safety critical profile for the vessel. The impact on the design of VIIS was judged to be minor and well within planned capabilities. Author
