Learn the latest process risk assessment technique for process control
Layer of protection analysis (LOPA) is a semiquantitative tool for analysing 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, such as a process hazard analysis (PHA), and can be used to meet the risk assessment requirements of IEC 61508 and 61511.
This course covers the basic methodology of LOPA and the detailed stages of its application. Participants are shown how significant scenarios are identified and how frequencies are estimated for the worst-case events. They are shown how to assign risk categories and therefore determine the number of independent protection layers (IPLs) that should be in place. The specification and requirements for a protection layer to be accepted as an IPL are discussed. All the essential steps in this method are practised in workshops, including the use of software tools in LOPA.
