ABSTRACT

During the service life of the offshore pipelines, different failure mechanisms like external/internal sheath damage, fatigue damage, or corrosion may arise. Therefore, high operating costs need to be consumed to confirm the fitness of the pipeline system. This research deals with an enhanced Risk-Based Inspection (RBI) methodology to certify the integrity management of the pipeline system, a radical new way of RBI practice is introduced for analysing steel pipeline and flexible pipeline. Case studies are executed to designate and give knowledge of how the technique works in exercise with what outcomes can be discovered. The discoveries present features of uncertainties which may not have been measured when implementing the traditional RBI scheme. The scope of this research is to display that with an efficient technique of execution the RBI practice, the failures of pipeline systems can be monitored and control system to ensures the integrity of the pipeline’s system.

摘要

在海上管道的使用寿命期间，可能会出现不同的失效机制，如外/内护套损坏、疲劳损坏或腐蚀。因此，需要消耗高昂的运行成本来确认管道系统的适用性。本研究涉及一种增强的基于风险的检查 (RBI) 方法来证明管道系统的完整性管理，引入了一种全新的 RBI 实践方法来分析钢质管道和柔性管道。执行案例研究以指定并提供有关该技术如何在练习中工作以及可以发现哪些结果的知识。这些发现呈现出在实施传统 RBI 方案时可能无法测量的不确定性特征。
