为确定深水防喷器系统中影响可靠性较大的关键单元设备及故障模式，采用 FMECA 方法对系统进行了分析。定义了系统基本情况、边界条件、故障模式和判断依据等 FMECA 分析的基本要素。分析结果表明，对深水防喷器系统可靠性危害性较大的单元设备为闸板防喷器、控制箱、液压连接器；危害性较大的故障模式有闸板封井不严、节流压井管线外漏、黄箱与蓝箱中有1个所有功能同时不能激活、黄箱或蓝箱中有1箱有1个功能不能激活、黄箱与蓝箱同时有1个功能不能激活。对深水防喷器系统设计、应用及日常维护提出了改进建议。

FMECA analysis method was applied to deepwater subsea BOP system in order to inves-tigate key unit equipment and fault mode in the system for more endangered system reliability. FMECA key element such as system essence thing,boundary condition,determinant criterion of failure mode was defined.Analysis result indicates that key unit equipments of more affecting reli-ability of deepwater subsea BOP severity are ram BOP,control pods,hydraulic connector.Simulta-neity,that fault modes of more severity are leakage through a closed ram,external leakage of choke and kill line,loss of all functions one pod,loss of one function one pod,loss of one function both pods.Improving advice on deepwater subsea BOP system,application,and daily maintenance is put forward according to analysis result.
