Fire risk assessment of a large passenger ship using computer simulation

Abstract

Fire accidents tend to cause larger damage to ships than other type of accidents, despite the fact that fire accidents account for 10% of total ship accidents. Therefore, in any safety regulations, prevention and mitigation of fire accidents are considered with high emphasis. In this paper, fire risk analysis of a large passenger ship is performed. Event tree is used to model fire scenarios considering the effect of fire detection and fire suppression. Then the design fire scenarios that need further study are selected from preliminary fire simulation results using zone model fire simulation and expert review. Field model fire simulation software is used to calculate the consequence of each selected design fire scenario door, windows and ventilation systems.
