摘要: 为分析海洋油气管道的失效可能性,首先建立海底油气管道失效可能性评价指标体系,它包括腐蚀、第三方破坏、环境、误操作、管道自身和安全管理6大方面的21个因素。考虑到诸指标间的影响,用熵权法与超标倍数赋权法相结合的改进综合权重法确定权重。用基于集对分析的海底油气管道失效可能性评价方法评价某海域5段不同的管段。根据指标分值,得出各管段最大联系度,以判定其失效可能性。结果表明,集对分析法对指标分值的处理结果与实际情况基本符合,可应用于海底油气管道的失效可能性分析。

Abstract: For the sake of analyzing submarine pipeline failure possibility, an evaluation index system was established. The index system consists of 21 factors of 6 aspects, including corrosion, third party damage, environment, misoperation, pipeline itself and safety management. weights of the indexes were determined by using the modified comprehensive weight method which combine the entropy weight method with the excessive multiples weight method. Lastly, the failure possibility evaluation method of submarine oil and gas pipeline based on set pair analysis was adopted to evaluate 5 different pipe sections in a certain sea. The maximum connection degrees of each pipe section were determined according to the evaluation scores to judge the failure possibility. The results show that the processing result of index score by set pair analysis conforms with the actual situation, and set pair analysis can be used in evaluation of failure probability of submarine pipelines.

Key words: submarine oil &, gas pipelines, failure probability, set pair analysis, comprehensive weight, connection degree
