Fire and Explosion Risk Analysis and Evaluation for LNG Ships

Abstract

Liquefied natural gas(LNG) has large fire and explosion hazard and China's imports of LNG by sea will present rapid growth in the next decade. Analyses were made for the fire fatalness of LNG ships. The risk evaluations of fire and explosion in the LNG ship were made at a different angle by use of the Dow method, BLEVE model and VCE model. The clear, accurate, comprehensive evaluation findings were obtained, in which the fire and explosion hazard index F&EI is 168 and the degree of risk is ‘very large’ before the security measure compensations, but after security measure compensations, fire and explosion risk index F&EI falls and the degree of risk is reduced,. The results could be applied as references to the scientific management and the adoption of safety measures for the shipping enterprises that plan and participate actively to import LNG project.
