Risk Assessment of a Hyperbaric Evacuation System
Abstract Risk Assessment is gaining increasing acceptance as a tool in addressing the safety of offshore operations. In addition to a complete assessment of an installation, which may form part of a Formal Safety Assessment, risk assessment techniques can be applied to specific safety related systems on a platform. This paper presents the results of a study of the risks associated with the hyperbaric rescue of divers. It includes the identification of accident scenarios, and analysis of consequences of such events as ship collision, fire or explosion. A particular feature of this assessment is the identification of effects which would impede evacuation, such as buckling of steel members, availability of strategic personnel, etc. The study therefore included analysis of effects of incidents both on hardware, and also on personnel and procedures. Incorporation of event frequencies then enabled calculations to be made of the risk to the divers during an emergency situation. In particular, comparison between the risks attached to different modes of evacuation enables decisions to be made, on safety grounds, with regard to the appropriate operational mode.
