摘要

In the chemical processing industry, intrinsically safe must be the process engineer's goal, but, in reality, it is often not feasible either technically or economically. In these cases, safety instrumented systems (SIS) are used to detect and respond to process risk. SISs have many components that must work as designed in order to mitigate potential hazardous incidents. Over the years, many of these components have evolved from simple electro-mechanical devices to complex mechanical, electrical, and programmable electronic devices. How these devices fail must be examined in order to understand how each component failure can propagate into failsafe and fail-dangerous conditions. This paper proposes the use of fault management analysis (FMA) for the assessment of proposed SIS designs. The FMA leads to the identification of not only the failure modes of each component, but also in the determination of how to appropriately manage the identified failure. This paper will provide examples of how FMA is used to assess SIS components. Then the paper will demonstrate how the proposed design, diagnostics, inspection, maintenance, and testing programs should be modified to improve the SIS performance.
