摘要
针对海上浮式风机系泊系统失效问题,本文采用故障树分析方法研究了系统故障失效风险。以浮式风机系泊系统失效为顶事件,分析系泊系统失效逻辑层次结构,建立浮式风机系泊系统失效故障树模型。采用定性与定量风险分析方法,辨识了浮式风机系泊系统主要失效模式和失效机理,计算了浮式风机系泊系统失效概率、可靠度、平均无故障时间和各底事件的关键重要度。研究结果表明:浮式风机系泊系统主要失效模式为锚链断裂和辅助设备故障,系统整体可靠度为99.88%,平均无故障工作时间约为800 h。开展的风险防控措施提高了浮式风机系泊系统安全可靠性。
This work focuses on the failure problem of offshore floating wind turbine mooring systems.The failure risk of offshore floating wind turbine mooring systems is studied through fault tree analysis.The logic hierarchy structure of mooring system failure is analyzed,and the model for the failure fault tree analysis of the failure of offshore floating wind turbine mooring systems is established by taking the failure of an offshore floating wind turbine mooring system as the top event.Qualitative and quantitative risk analysis methods are used to identify the main failure modes and failure mechanisms of the offshore floating wind turbine mooring system and calculate the failure probability,reliability,and mean time between the failures of the offshore floating wind turbine mooring system.The critical importance of each bottom event is analyzed by applying the critical importance analysis method.Results show that the main failure modes of the offshore floating wind turbine mooring system are anchor chain breakage and auxiliary equipment failure.The overall system reliability of the system is 99.88%,and the mean time between failures is approximately 800 h.Risk prevention and control measures are implemented to improve the safety and reliability of floating offshore wind turbine mooring systems.
