Interlinking HAZOP and SIL for Well Intervention and Workover Systems
As per today, there are no specific Safety Integrity Level (SIL) requirements for barriers in well intervention and workover systems. However, during well intervention, the SIL classified and validated Safety Instrumented Function (SIF) (according to OLF 070) in the subsea XMT is bypassed.
ORS has developed a methodology for the SIL classification and validation process for well intervention and workover systems. By interlinking a customized HAZOP with a LOPA and SIL validation process, the SIFs identified for various operational modes can be classified and validated.
