Development of a layer of protection analysis tool to determine the safety integrity level in process industries

The purpose of this study was to develop a tool to determine the Safety Integrity Levels (SILs) using Layer of Protection Analysis (LOPA) method. Various methods can be used in determining this SIL. However, LOPA has been chosen as the risk-based approach to evaluate the potential consequences and l...
