Abstract:	The performance of heat insulation of marine structures is investigated using numerical simulation, Eurocode's formula calculation, and experimental measurement. Two popular fire protection materials of rock wool 60k (60 kg/m(3)) and ceramic fiber 80k (80 kg/m(3)) are chosen to show the requisite minimum thickness for marine structures to meet the regulation of IMO heat insulation A-class. Compared with the results of Eurocode's formula calculation and experimental measurement, the effectiveness of the heat insulation performance of marine structures, predicted from numerical simulation, can be demonstrated. The numerical simulation shows that the heat insulation performance of marine structures with fire protection material of ceramic fiber (25 mm) or rock wool (50 mm) meets the requirement of A-30 class. Though there is an obvious difference between the results from numerical simulation and experimental measurement during heating process, the fire protection materials combined with ceramic fiber (25 mm) and rock wool (25 mm) and under the condition of the ceramic fiber exposed to fire can still satisfy the requirement of a heat insulated A-60 class bulkhead.
