摘要: 为提高海上浮式生产储油卸油设备(FPSO)模块吊装作业的安全性,利用专家评判和事故树分析法(FTA)对作业流程进行风险分析。首先,通过统计分析辨识出尽可能多的基本事件,构建事故树模型;其次,引入区间二元语义理论来描述不确定性和模糊性的专家评判观点,同时考虑专家权重和观点间的相似程度2个方面,聚合得到综合性的群体观点;然后,通过Fussell-Vesely重要度排序,辨识出风险等级较高的事件;最后,对南海某油田的FPSO模块吊装过程进行风险分析。结果表明:该作业流程风险评价等级处于中等和高等之间,设备问题是主要的高风险事件,与事故统计数据一致,验证了该风险分析方法的合理性。

Abstract: In order to improve operation safety of FPSO module hoisting, risk analysis of operation process is carried out by using expert evaluation and FTA. Firstly, basic events were identified as many as possible based on statistical analysis, and a fault tree model was constructed. Secondly, interval 2-tuple theory was introduced to describe uncertain and fuzzy evaluation opinions of experts, and general opinions were aggregated after considering expert weights and similarity between their opinions. Then, high-risk events were identified according to Fussell-Vesely ranking of importance. Finally, with an oil field in South China Sea was as an example, risk analysis of its FPSO module hoisting project was carried out. The results show that its operation process risk ranks between medium and high, and equipment problem proves to be a major high-risk event, which are all consistent with statistical data of accidents, thus verifying rationality of this risk analysis method.

Key words: floating production storage and offloading(FPSO), fault tree analysis (FTA), module hoisting, interval 2-tuple, group view aggregation, risk analysis
