为预防和减少油气管道设施维检修及施工过程中人员伤亡等事故,开展了油气管道设施的锁定管理方法研究.通过对油气管道设施维检修和动火作业过程中危险源、能量释放途径的分析,基于风险管理理论,借鉴国外大型石油石化企业锁定管理经验,提出了适合中国油气管道特点的锁定管理方法,形成了简洁、实用的锁定管理工作程序,并结合实际应用提出了实施风险分级管控、制定专项安全检查表、开展相关技能培训及实施PDCA(Plan Do Check Act)循环管理4项关键内容.实践结果表明:锁定管理方法遵循PDCA循环管理模式,实行分级管控,通过规范员工职责,落实和强化作业过程监控,持续完善锁定管理工作程序,有助于现场HSE风险管理水平的提升.研究结果为油气管道企业有效实施锁定管理提供了有益的借鉴,并指出了锁定管理的下一步发展方向.(图1,表2,参21)“,”In this paper, the lock management method for oil and gas facilities was studied to prevent and reduce the accidents during the maintenance & repair or construction of oil & gas pipeline facilities, such as casualty. Firstly, hazard source and energy release pathway during maintenance & repair or hot works of oil & gas pipeline facilities were analyzed. Secondly, based on the theory of risk management, drawing on the experience of lock management in large petroleum and petrochemical enterprises abroad, this paper puts forward a lock management method suitable for the characteristics of Chinese oil and gas pipelines, and forms a simple and practical lock management procedure. Thirdly, combined with the actual application, 4 key contents were put forward, i.e., implementing risk classification control, preparing a special safety check list, carrying out related skill training and implementing PDCA (Plan Do Check Act) cycle management. The practice results show that the lock management method following the PDCA cycle management mode, implements classification management, standardizes staff duties, implements and strengthens the monitoring process, continuously improves the lock management procedure, it is helpful for the HSE risk management level. The research results provide a useful reference for the effective implementation of lock management in oil and gas pipeline enterprises, and point out the next development direction of lock management.
