摘　　要：针对海上油气处理系统开展RCM分析时专家意见分散这一情况,采用熵权模型对各专家的评分计算筛选,确定权重排序后,再进行详细的FMEA分析。结果表明:熵权模型的建立和应用识别出了50%的低风险等级设施,将分析关注重点聚焦于高中风险设施;对故障模式进行安全、环境、生产损失和维修成本FMAE分析,给出了采用状态监测、故障检测、定期更换或修复、改进性维修方向性操作以及采用维护点检措施,包括机械常规检查、机械状态监测、电气检查、仪表检查、联锁检查、绝热检查的维护检修策略。Consideringthe mixed opinions of experts on the RCM analysis of offshore oil - gas processing systems, anentropy weight model was used to calculate and screen the experts＇ scores, followed by a detailed FMEA analysis was conducted with determined weight ranking. The application results showed that： the establishment and application of the entropy power i- dentified 50% of the low - risk facilities, focusing on facilities with medium and high risk; FMEA of the failure mode was conducted for safety, analysis environ- ment, production losses and maintenance costs, and it provided co of condition monitoring, fault detection, periodic replacement or repair, improved maintenance of directional operation and the maintenance of point inspection, including routine mechanical inspection, mechanical condition monito- ring, electrical inspection, instrument inspection, in- terlocking examination, maintenance strategy of adiabatic check.
