Shetty, N.K., Guedes Soares, C., Thoft-Christensen, P. and Jensen, F.M. (1998), “Fire Safety Assessment and Optimal Design of Passive Fire Protection for Offshore Structures", Reliability Engineering and System Safety, Vol. 61, pp. 139-149

The article presents a unified probabilistic approach to fire safety assessment and optimal design of passive fire protection on offshore topside structures. The methodology was developed by integrating quantities risk analysis (QRA) techniques with the modern methods of structural system reliability analysis (SRA) and reliability based design optimisation (RBDO). Reliability analysis methodologies are presented for both plated (e.g. fire and blast walls) and skeletal structures (deck framing), which take into account uncertainties in fire and blast loading, thermal and mechanical properties of the steel and insulation. Probvability of component and system failure are evaluated using first-and second-order reliability methods (FORM/SORM). The optimisation of passive fire protection is performed such that the total expected cost of the protection system is minimised while satisfying reliability constraints.
