LOPA module integration FPSO

MAR Consulting was contracted to support with a layers of protection analysis (LOPA) of one module integration in a floating production, storage and offloading (FPSO) vessel. The project may require additional barriers to protect the new equipment to be installed. These barriers can be, among other options, safety instrumented functions (SIF).

LOPA is one method to allocate safety integrity levels (SIL) to SIFs if additional risk reduction is necessary. The objectives of the LOPA/ SIL allocation were to:

  • Verify if the existing barriers are sufficient, and the risk level is sufficiently reduced such that the tolerability criteria is achieved to support the ALARP demonstration.
  • Establish potential SIL requirements to instrumented functions.

MAR Consulting used its extensive expertise in functional safety to facilitate and record a SIL allocation workshop (LOPA in this case). You are welcome to contact us if you need further understanding of your barriers against specific hazardous scenarios and ensure your risk is tolerable.
