SYSTEM SAFETY ANALYSIS OF A COMMERCIAL VESSEL

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) identify/define needed modifications to VIIS as currently being developed for the Coast Guard. The safety analysis was limited to a study of fire/explosion hazards in the vessel's cargo/cargo 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)
