The paper presents a unified, fully-probabilistic approach to fire safety assessment and optimal design of fire protection on offshore topside structures. The methodology has been developed by integrating Quantitative Risk Analysis (QRA) techniques with the modern methods of Structural System Reliability Analysis (SRA) and Reliability Based Design Optimization (RBDO). The integration has been achieved by using platform-specific extended event-trees which model in detail the escalation paths leading to the failure of Temporary Refuge (TR), Escape, Evacuation and Rescue (EER) systems or structural collapse of the topside. Probabilities of events for which historical data are not generally available are calculated using structural reliability methods. The optimization of fire protection is performed such that the total expected cost of the protection system and the cost of failure of the platform (loss of life, loss of asset, environmental damage) is minimized while satisfying reliability constraints.
