Safety Integrity Level (SIL) / Layers of Protection Analysis (LOPA)

In addition to offering qualitative Process Hazard Analysis (PHA) services, Insight PSM is qualified to offer semi quantitative risk assessment studies such as Layers of Protection Analysis (LOPA) which can be delivered as a standalone analysis and/or as a follow up on PHA to further analyze high risk scenarios.

LOPA analysis can result in highlighting the need for Safety Instrumented Systems and hence drive the need for completing SIL Determination Analysis.
