由于晃荡、液货加热等原因,油船液货舱上层空间存在大量的油气,随着油气的不断逸出和扩散,致使油船存在着污染、人员中毒、油气燃烧和爆炸等潜在风险。针对危险性最大的液货舱爆炸风险,文中运用人-机-环境-管理系统理论方法构建油船晃荡液货舱爆炸风险贡献树框图,使用专家调查法确定因素权值大小,运用模糊评判法进行风险度计算,得出油船晃荡液货舱存在的爆炸风险值,并提出了相应的控制措施。
Due to sloshing and heating of cargo tanks, there is a large amount of oil and gas in the upper space of the tanker’s liquid cargo tank. With the continual escape and spread of oil and gas, oil tankers have the potential risks of pollution, personnel poisoning, oil-gas combustion and explosion. In view of the explosion risk of the most dangerous liquid tank, the paper uses the theory of man-machine-environment-management system to build the tree diagram of explosion risk contribution of oil tank sloshing tank. Using expert investigation method to determine the weight of factors, Calculation, obtained the tanker sloshing liquid cargo explosion risk value, and put forward the corresponding control measures.
