Notes:
A one-dimensional finite element model, associated with a computer code, has been developed to simulate the thermal response of a decomposing glass-fibre reinforced composite exposed to a fire environment. The numerical model uses a first-order Arrhenius equation and includes: transient heat conduction; gas mass flux and internal heat convection of decomposition gases; density loss and Arrhenius decomposition of active material into decomposition gases and residual char; and endothermicity of the decomposition process. An empirical formula, obtained from furnace tests, has been applied to the model as the incident heat flux boundary condition at the heated surface. Presents results for the standard thickness of polyester-based GRP laminate, 10.9mm, for offshore structures. The predicted temperature profiles are in good agreement with experimental temperatures obtained from furnace tests. This model is able to simulate fire performance characteristics for a large range of typical offshore components with different constructions and materials. It will enable accurate predictions of the life-time of offshore components in severe offshore hydrocarbon fires.
