Abstract
The objective of this paper was to introduce more advanced and practical procedures for fire load application methods considering the effects of Passive fire protection (PFP) with the motivation to nonlinear structural consequence analysis of FPSO topsides structures under fire load. This paper is a part of phase III of the joint industry project on explosion and fire engineering of FPSOs (EFEF JIP). Temperature dependent material properties of steel and PFP materials were adopted to develop fire load application methods. But in case of PFP materials, only temperature dependent thermal properties were considered to focus on the thermal effects. Numerical simulations were performed and the modeling method of PFP materials were validated with published experimental results. The nonlinear finite element code LS-DYNA was used for numerical simulations. The results of this study will be useful for consequence structural analysis under fire load considering PFP effects.
