Layer of Protection Analysis (LOPA)
Layer of protection analysis (LOPA) is a quantitative tool for analyzing and assessing risk on a process plant.
It uses an order of magnitude technique to evaluate the adequacy of existing or proposed layers of protection against known hazards. LOPA typically builds on the information developed during a qualitative hazard evaluation and can be used to meet the risk assessment requirements of IEC 61508 and 61511. The course will cover the theory as well as the application of the methodology for process relevant scenarios.
