A method for determining fire accidental loads and its application to thermal response analysis for optimal design of offshore thin-walled structures

Authors: J.K. Seo, S.E. Lee & J.S. Park

Abstraact:
More than 70% of accidents that occur on offshore installations stem from hydrocarbon fire and explosion, and as
they involve heat and blast effects, they are extremely hazardous with serious consequences in terms of human
health, structural safety and the surrounding environment. To prevent further accidents, substantial effort has
been directed towards the management of fire and explosion in the safety design of offshore installations. The aim
of this paper is to present a risk-based methodology procedure to help determine the fire accidental design load of
an offshore installation (AL Living Quarter) in association with the thermal response characteristics for structural
optimisation. A probabilistic sampling approach with numerical fire simulations was taken to determine the fire
accidental load. To determine the optimisation of the thin-walled structures of the living quarter, an A60 based on
the results of thermal response analyses was conducted and the temperature distribution calculated. The analysis
results suggest incorporating both the design and safety planning aspects of offshore Living Quarter.
