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
