Abstract Risk analysis is of paramount importance in maritime transportation due to the nature of work. The IMO (International Maritime Organization) adopted FSA (Formal Safety Assessment) as guidance to address risk analysis on-board ship. However, it does not suggest a specific approach on how to assess the risks. Therefore, safety researchers are seeking robust risk analysis approaches in maritime transportation. This paper performs comprehensive risk analysis by using bow-tie method within a fuzzy logic environment. While the bow-tie method is analysing potential causes and consequences of failures, the fuzzy logic deals with vagueness and imprecision of expert judgements. The case of cargo liquefaction on-board ship is selected as a case study since the consequences of cargo liquefaction are extremely dangerous for crew, ship and environment. Besides its theoretical insight, the paper supports maritime professionals to enhance safety awareness about the cargo liquefaction phenomenon.

模糊逻辑在船舶货物液化风险故障树和事件树分析中的应用

摘要 由于工作性质，风险分析在海上运输中至关重要。IMO（国际海事组织）采用 FSA（正式安全评估）作为解决船上风险分析的指南。但是，它没有建议如何评估风险的具体方法。因此，安全研究人员正在寻找强大的海上运输风险分析方法。本文在模糊逻辑环境中使用领结法进行综合风险分析。领结法分析故障的潜在原因和后果，而模糊逻辑处理专家判断的模糊性和不精确性。选择船上货物液化的案例作为案例研究，因为货物液化的后果对船员、船舶和环境都是极其危险的。
