摘要
安全完整性等级(SIL)是一个重要的安全可靠性参数,用以表征安全相关系统针对一个特定的功能要求所能达到的风险降低的程度。介绍了海洋石油工程中安全完整性等级分析中常用的保护层分析法(LOPA),并结合实例介绍了其在安全完整性等级分析上的应用和用其来确定安全仪表系统的完整性等级的方法。
SIL is an important safety reliability parameter,which is used to represent the degree of risk reduction of safety related system for a specific functional requirement.This article introduced the commonly used layer of protection analysis(LOPA)in the safety integrity level analysis of offshore oil engineering,and introduced its application in the safety integrity level analysis and the method of using it to determine the integrity level of safety instrument system.
