|Abstract: ||Abstract:The performance of heat insulation of ship structure is investigated by using numerical simulation, Eurocode’s formula calculation and experiment measurement. Two popular fire protection materials of rock wool 60k (60 kg/cm3) and ceramic fiber 80k (80 kg/cm3) are chosen to show the requisite minimum thickness for ship structures to meet the regulation of IMO heat insulation A class. Compare with the results of Eurocode’s formula calculation and experiment measurement, the effectiveness of the heat insulation performance of ship structures predicting from numerical simulation can be demonstrated. The result shows that the heat insulation performance of ship 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 obvious difference between the results from numerical simulation and experiment measurement during heating process, the fire protection materials combine with ceramic fiber (25 mm) and rock wool (25 mm) and expose the ceramic fiber to fire, can still satisfy the requirement of heat insulated A-60 class bulkhead.|
