摘要 随着我国海洋油气资源开发的快速发展,海底管线的建设数量不断增多。由于荷载与环境因素的长期作用,海底管线因为材料老化和损伤累积而导致结构状态退化和承载能力降低的情况十分普遍。为了保证海底管线的安全运行,急需建立我国的海底管线全寿命安全管理体系。该文首先分析了海底管线全寿命安全运行的关键问题,然后概括介绍了大连理工大学在海底管线损伤机理与健康监测方面取得的研究进展,并对今后的研究方向进行了总结与展望。 With the rapid developments of offshore oil and gas explorations, the construction of subsea pipelines is becoming more and more in China. Due to the long-term effects of loading and enviromental factors, the material aging and damage accumulation may lead to the deteriation of strcural status and load-beating capacity for subsea pipelines. To keep the safe serive, the safety management of subsea pipelines should be established during the life-cycle operation. Fistly, the critical issues on life-cycle service for subsea pipelines were analyzed in the paper. Then the research activities in Dalain University of Technology were briefly reviewd for the damage mechanism as well as structural health monitoring of subsea pipelines. Finally, the issues for future research were put forward.
