摘要： 近年来海底管道由于腐蚀缺陷造成失效的事件有增多的趋势。为了评估在管道发生腐蚀后失效的风险性，对DNV-RP-F101的腐蚀管道强度评估方法进行研究，通过算例对影响强度评估的关键因素进行了敏感性分析，并对DNV-RP-F101和DNV-OS-F101的关系进行了探讨。结果表明，影响强度评估结果的三个主要因素中，缺陷检测数据误差对评估结果影响最大。当满足一定条件时，屈强比对评估结果的影响可忽略。

Abstract: The failure of submarine pipelines due to corrosion defects has an increasing tendency in recent years. In order to assess the failure risk when corrosion occurs, we present a review of the strength assessment procedure of DNV-RP-F101. The parameters which will impact on burst pressure are studied. And the relation between DNV-RP-F101 and DNV-OS-F101 is discussed. Based on the calculation results, the following conclusion can be made. Among the key parameters, the inspection accuracy has the greatest influence on the strength assessment results. When certain condition is satisfied, the ratio of yield to tensile is negligible.
