Towards Safer Operations: An Integrated Approach for Determining SIL in Delayed Coker Units through HAZOP and LOPA
This paper presents an integrated HAZOP, LOPA, and risk graph framework to systematically determine Safety Integrity Levels (SIL) for safety instrumented functions during modifications to Delayed Coker Units, demonstrating its application in justifying the addition of UV-scanner trip signals while identifying necessary safeguards to close risk gaps and ensure operational safety.
