The development of optimum strategies for emergency response for offshore installations
Safety aspects influencing emergency response on offshore installations and the influence of economic, legislative, safety management and safety engineering factors on the safety of the workforce are reviewed. The main objective of developing optimum strategies for emergency response is to reduce the risk to personnel by reducing the likelihood of precipitate or inappropriate decisions being made. This involves a judicious balance of significant predictive factors, namely: the estimated risk to personnel whilst remaining onboard and during evacuation, escape, recovery and rescue; and the estimated time required to gain control of an undesired event (or reach untenable conditions) and for evacuation and escape. The research focuses on the provision of significant information to the Offshore Installation Manager (OIM). A methodology is presented to assist in the development of optimum strategies for emergency response and in the design of a computer-based Emergency Response Information (ERI) system for providing the information. A fiamework is presented to assist in: identifying events, sequences and combinations of events and their potential consequences; and defining event type, severity and priority for emergency response. Typical resources and arrangements for responding to emergencies are reviewed and their adequacy for the effective employment of the ERI system evaluated. Typical information required at applicable activity stages is identified for defined areas of emergency response for events of varying degrees of severity. A statement of sensible and feasible' requirements of a typical ERI system is presented. A critical evaluation is presented of the feasibility of the design, manufacture and operation of the ERI system to provide the information and achieve specified requirements, namely: performance standards (functionality, reliability and survivability); and ergonomic and human resources requirements. The research concludes by examining ways in which the philosophy described in the thesis can be implemented in practice. A methodology for presenting the information is described.
