摘要:

为了计算海底管道在腐蚀缺陷下的可靠性,评估分析了海底管道的风险分值和风险等级。基于DNV腐蚀因素失效概率模型评估海底管道可靠度,计算在不同腐蚀深度情况下的可靠性指数和失效概率,评定其安全等级。根据DNV-OS-F101-2007规范识别海底管道风险因素和风险评分,给出海底管道风险评估流程,确定管道的风险分值和风险等级,为海底腐蚀管道输送高压天然气风险评估提供参考。

Abstract: In order to calculate the reliability of submarine pipelines under corrosion defects, the risk score and risk grade of submarine pipelines are evaluated and analyzed. Based on the failure probability model of DNV corrosion factors, the reliability of submarine pipelines is evaluated, and the reliability index and failure probability under different corrosion depths are calculated, and the safety grade is evaluated. According to the DNV-OS-F101-2007 specification, the risk factors and risk score of submarine pipelines are identified. The risk assessment process of submarine pipelines is given, and the risk score and risk grade of pipelines are determined. It can provide reference for risk assessment of high pressure gas pipeline transmission by submarine corrosion pipelines.
