安全仪表功能管理

Safety Instrumented Function Management

过去的这些年,社会经济的不断发展使得过程工业的规模越来越大,带来的整体系统所面临的风险也随之增加,在以石油/天然气开采运输、石化、化工、发电等为代表的过程工业领域,紧急停车系统(ESD)、燃烧器管理系统(BMS)、火灾和有毒有害可燃气体检测保护系统(FGS)、高完整性压力保护系统(HIPPS)等以安全保护和抑制减轻灾害为目的的安全仪表系统(SIS),已广泛应用于不同的工艺或设备防护场合,保护人员、生产设备及环境,但是对于在役安全仪表系统的维护和安全仪表功能的管理还存在诸多挑战,本文结合功能安全标准,给出了安全仪表功能的管理内容。

In the past few years, social economy development has increased the size of the process industry and the risks of the overall system. In oil/gas transportation, petrochemical, chemical, power generation, and other process industrial field, the emergency shutdown system(ESD), burner management system(BMS), fire and gas detection system(FGS), high integrity pressure protection system(HIPPS) with safety protection and inhibition of disaster relief for the purpose of safety instrument system(SIS), has been widely used in different process or equipment protection, protection of personnel, production equipment and the environment, However, there are still many challenges to the maintenance of safety instrument system and the management of safety instrument function. This paper combines with the function safety standard to give the management content of safety instrument function.
