海底管道泄漏监测系统可行性分析

Feasibility analysis of subsea pipeline leak detection system

对于海底管道来说,管道泄漏会造成巨大的经济损失,对人身安全以及海洋生态环境产生重大的威胁。管道泄漏监测系统的目的是尽早发现泄漏并找到泄漏位置,从而减少经济损失和对环境的破坏。介绍了适用于海底管道泄漏监测的4种方法:参数计算法、次声波法、光纤法和气体监测法,并对其工作原理分别进行了分析。针对海底管道泄漏监测系统所要求的性能指标,分别赋予4种方法以相应的权重和等级,计算每一种检测方法的分值,结果表明,参数计算方法得分最高,是最合适的海底管道泄漏监测方法。

Pipeline leaks could normally cause huge economic losses and have significant threats to personal safety and ma- rine ecological environment. The primary purpose of applying pipeline leak detection system is to detect and locate leak as early as possible, so as to reduce economic loss and damage to the environment. This paper introduces four methods suitable for subsea pipelines： computational pipeline monitoring method, infrasonic detection method, optical fiber detec- tion method and gas detection method, and their working principles are analyzed respectively. According to the perfor- mance indexes required by subsea pipeline leak detection system, the corresponding weights and ratings of the four methods are given, then the score for each detection method is obtained. The results show that computational pipeline monitoring method getting the highest score is the most suitable for subsea pipeline leak detection.
