Course description
This course will develop your understanding of the Layer of Protection Analysis (LOPA) methodology and how to apply it. LOPA is a semi-quantitative tool used for analysing and assessing risk on a process plant which 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 include LOPA research papers, reference materials and further reading.

Reviews
Average rating 5
It offered a good balance of theory and practical. I enjoyed the practical application elements which really helped reinforce my learning.
I liked the structured approach. I learnt a lot from Nigel. Nigel is very accommodating and his many years of experience comes through as he explains concepts and approaches. We...
