Gas inerting process is a great hazard for chemical tanker ships and utmost care is required considering the harmful effects to humans’ health. Most of the chemical tanker ship-owners face near-miss or accident (asphyxia/fire/explosion) during gas inerting process on-board ship. The consequences of the process may pose catastrophic results such as explosion, fire or asphyxiation. Therefore, a detailed risk assessment is required to enhance the process of safety during the carriage of chemical cargo and minimize potential consequences. To address this concern, the paper aims at conducting a systematic probabilistic analysis of asphyxiation risk during gas inerting process in chemical tanker ship. In the paper, a Bayesian belief network (BBN) method is used to deal with causality and uncertainty arising from the complex interdependence between variables in the probabilistic risk assessment of asphyxiation risk. While BBN enables us to calculate the conditional probability of each intermediate node and leaf node in the graph and perform probabilistic risk assessment with sensitivity analysis, fuzzy logic deals with the translation of linguistic expressions from expert opinion into probability values. The findings of the paper will provide the utmost contribution for chemical tanker ship owners, safety researchers, maritime safety professionals, and HSEQ managers (Health, safety, environment, and quality) to prevent the risk of asphyxiation during gas inerting process in maritime transportation.

化学品船气体惰化过程窒息概率风险评估

气体惰化过程对化学品油轮来说是一个很大的危害,考虑到对人类健康的有害影响,需要格外小心。大多数化学品船船东在船上气体惰化过程中面临险情或事故(窒息/火灾/爆炸)。该过程的后果可能会造成灾难性后果,例如爆炸、火灾或窒息。因此,需要进行详细的风险评估,以加强化学品货物运输过程中的安全性并尽量减少潜在后果。为了解决这个问题,本文旨在对化学品油轮气体惰化过程中的窒息风险进行系统的概率分析。在论文中,使用贝叶斯信念网络 (BBN) 方法处理窒息风险概率风险评估中变量之间复杂的相互依存关系引起的因果关系和不确定性。BBN 使我们能够计算图中每个中间节点和叶节点的条件概率,并通过敏感性分析进行概率风险评估,而模糊逻辑则处理语言表达从专家意见到概率值的转换。该论文的研究结果将为化学品船船东、安全研究人员、海事安全专业人员和HSEQ经理(健康、安全、环境和质量)提供最大的贡献,以防止海上运输气体惰化过程中的窒息风险。BBN 使我们能够计算图中每个中间节点和叶节点的条件概率,并通过敏感性分析进行概率风险评估,而模糊逻辑则处理语言表达从专家意见到概率值的转换。该论文的研究结果将为化学品船船东、安全研究人员、海事安全专业人员和HSEQ经理(健康、安全、环境和质量)提供最大的贡献,以防止海上运输气体惰化过程中的窒息风险。BBN 使我们能够计算图中每个中间节点和叶节点的条件概率,并通过敏感性分析进行概率风险评估,而模糊逻辑则处理语言表达从专家意见到概率值的转换。该论文的研究结果将为化学品船船东、安全研究人员、海事安全专业人员和HSEQ经理(健康、安全、环境和质量)提供最大的贡献,以防止海上运输气体惰化过程中的窒息风险。模糊逻辑处理语言表达从专家意见到概率值的转换。该论文的研究结果将为化学品船船东、安全研究人员、海事安全专业人员和HSEQ经理(健康、安全、环境和质量)提供最大的贡献,以防止海上运输气体惰化过程中的窒息风险。模糊逻辑处理语言表达从专家意见到概率值的转换。该论文的研究结果将为化学品船船东、安全研究人员、海事安全专业人员和HSEQ经理(健康、安全、环境和质量)提供最大的贡献,以防止海上运输气体惰化过程中的窒息风险。
