海洋石油平台溢油风险评价研究

Risk assessment of oil spill on the offshore platform

通过层次分析法,系统分析了我国钻井平台及生产平台的溢油风险因子,初步建立了该类设施的溢油风险评价指标体系,并运用多级模糊综合评级模型对目标设施的溢油风险进行综合评价。利用该评价方法对渤海某一钻井平台进行溢油风险分析,结果表明该平台溢油风险等级较低,风险因子中海区环境及平台疲劳老化程度的风险相对突出。该评价方法可及时判断目标设施的溢油风险等级,为减少、预防各类平台溢油事故提供技术支持。

In this paper, the risk assessment system of oil spill for offshore platform was established by analyzing the risk factors related to oil-spill potentials of drilling and production platform based on the current situations of facilities in China. A fuzzy comprehensive model was used to evaluate the degree of oil spill on target facility. A drilling platform service in the Bohai Sea was used to calculate the oil-spill risk in order to illustrate how to apply the developed approach. The results showed that the oil-spill risk level for the example target platform was relatively low, and the main risk factors were sea environment and fatigue. The risk assessment approach could provide technical support for oil-spilling prevention and reduction on offshore platform.
