Overview

Learn the methodology and detailed application of LOPA

Layer of protection analysis (LOPA) is a semi-quantitative 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.

The course will help you understand how significant scenarios are categorised and tolerable frequencies assigned for identified hazardous events. You will also learn to assign risk categories and determine how many Independent Protection Layers (IPLs) should be in place. The course also covers the specification and requirements for a protection layer to be accepted as an IPL.

All the essential LOPA steps are practised in workshops, including the use of software tools. Course materials also include a compendium of LOPA research papers, reference materials and further reading.
