海底滑坡是近海管道的一大隐患。管道布线方案的比较和优化以降低潜在的海底滑坡风险是近海油气开发工程中的一个关键问题。提出了一种改进的海底滑坡多发区近海管线布线优化的群决策评价方法。考虑到工程地质勘察信息和数据的不完备性，提出了信息完整性变量来调整各因素的权重。引入专家判断矩阵的相似度和差异度计算各专家的可信度，对信息完整性变量、相对权重和隶属度进行修正。在此基础上，根据多数原则，得到了海洋管道选线的群决策方法。最后，应用该方法对南海北部白云凹陷海底峡谷区管线布线优化进行了实例评价。结果表明，该群决策方法能够提高主观环境下海洋管道布线方案评价的客观性。
Submarine landslides are a great hazard to offshore pipelines. The comparison and optimisation of pipeline routing schemes to reduce the potential submarine landslide risk is a key issue in offshore oil and gas development engineering. This paper presents an improved group decision-making evaluation method for offshore pipeline routing optimisation in areas prone to submarine landslides. An information integrity variable is proposed to adjust the relative weight of each factor considering the incompleteness of the engineering geological survey information and data. The credibility level of each expert involved in the evaluation, which is calculated based on the similarity and difference of the experts’ judgment matrices, is introduced to correct the information integrity variable, relative weights, and memberships. The group decision-making for offshore pipeline routing selection is then obtained based on the principle of the majority rule. Finally, a case of pipeline routing optimisation in the submarine canyon area of the Baiyun depression, northern South China Sea, is assessed by using the proposed method. The result shows that the proposed group decision-making method can enhance the objectivity of the assessment for the offshore pipeline routing optimisation under a subjective environment.
