Abstract:

With the advent of Safety Integrity Levels (SIL) representing the relative reliability of instrumented protection systems in a quasi-quantitative manner, there has been a stirring interest by engineers seeking to understand where quality failure rate data can be obtained. This paper addresses that issue in the context of the Center for Chemical Process Safety (CCPS) initiative regarding operation of an industry Process Equipment Reliability Database (PERD). The work performed to date regarding instrument loops will demonstrate the overall project, the importance of failure mode definitions and what it takes to obtain high quality trusted data that can be turned into useful information.
