ABSTRACT Aircraft carrier hangars require sufficient space to enable essential functions such as aircraft preparation, stowage, handling of aviation fuel and munitions, etc. Consequently, the hangars are treated as high-fire-risk spaces owing to their operating conditions. Although hangar fire accidents are caused by various temporally and spatially varying fire hazards, fire safety designs for hangars follow a deterministic approach based on IMO regulations, similar to ro-ro ships. Hence, this paper proposes one hundred credible fire scenarios to enhance the fire safety design of hangar structures by utilizing Latin hypercube sampling. These fire scenarios were also employed to determine fire-induced loads in the form of exceedance curves. Moreover, the effect of fire frequency defining method and ship motions on fire consequences was quantitatively investigated through case study and CFD simulation.
