腐蚀海底管道剩余强度的可靠性模型及评估研究

Research on Reliability of the Model and the Assessment of Corrosion Residual Strength of Submarine Pipeline

为了制订行之有效的海底管道检修方案,有效地保障海底管道的安全运营,极有必要对腐蚀海底管道的剩余强度进行可靠性评估。本文首先阐述了海洋环境对海底管道腐蚀的影响因素,其次建立了腐蚀海底管道可靠性模型;同时还以某腐蚀海底管道为例,进行了可靠性评估,为海底管道的维护管理提供了科学的依据。

In order to develop effective submarine pipeline maintenance scheme, effectively ensure the safety of subma-rine pipeline operation, it is extremely necessary to corroded submarine pipeline residual strength reliability evaluation. The paper firstly elaborated the marine environment for submarine pipeline corrosion influence factors, then, established reliabil-ity model of corroded submarine pipeline, at the same time, took a corroded submarine pipeline as an example, did the relia-bility assessment of submarine pipeline, provided scientific basis for maintenance and management.
