The article presents a unified probabilistic approach to fire safety a
ssessment and optimal design of passive fire protection on offshore to
pside structures. The methodology was developed by integrating quantit
ative risk analysis (QRA) techniques with the modem methods of structu
ral system reliability analysis (SRA) and reliability based design opt
imisation (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 loa
ding, thermal and mechanical properties of the steel and insulation. P
robability 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 co
nstraints. (C) 1998 Elsevier Science Limited.
