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. © 2019 China Safety Science Journal.
