Brochure (PDF)This is a two day course which covers the principles of Layer of Protection Analysis (LOPA).
LOPA is a semi-quantitative risk assessment technique, and is the most commonly used method of SIL determination (i.e. of calculating whether a situation requires further risk reduction to meet tolerable risk targets, and if so, what reliability (SIL) is required of these further measures).
This training course is primarily for HazOp facilitators who also want to be able to lead LOPAs. However, it is suitable for anybody who wants to gain an in-depth understanding of the LOPA technique, and how to apply it. The course is taught using a combination of classroom teaching and group exercises, which are based on the CCPSCentre for Chemical Process Safety concept book “Layer of Protection Analysis – Simplified Risk Assessment”.

Day 2
Who Should Attend
This course is primarily for HazOp facilitators who also want to be able to lead LOPAs. However, it is suitable for anybody who wants to gain an in-depth understanding of the LOPA technique, and how to apply it.
Prior Knowledge
In order to get the most out of this course, it is recommended that delegates have at least some prior knowledge of hazard studies (e.g. from having either led HazOps, or attended enough of them as a team member to have a good understanding of how the HazOp process works). The course builds on the material presented in our HazOp Training Course for Study Leaders course. However, no prior knowledge of LOPA is required.
After this training course you will be able to:
After this course experienced HazOp leaders will be able to also facilitate LOPA studies *. Experienced hazard study team members will be able to participate effectively in LOPA as team members.
* A period of mentoring is recommended for all new LOPA facilitators. If required, =Method can provide a mentor to help new facilitators get off to the best possible start – please contact us to discuss your needs.
What you will get
- The course material in printed format.
- A certificate of attendance for each delegate that attends the full course. (16 hours of CPD)

Interesting and engaging. Real world examples were used multiple times which helped us understand the material better.
Clear, enthusiastic and engaging.
Very good, I liked David's style
I would highly recommend it.
Really enjoyed the course, thank you
Highly Recommended. David is very knowledgeable and passionate about Process Safety and LOPA.
Happy to recommend this course
David is one of the best engineering trainers i have come across. He is able to demonstrate complex high tech details effectively.
The trainer was really excellent!
Great foundation course for participating and leading LOPAs
Good content, very well presented
Overall the experience was excellent
I recommend this course
Enjoyed the background on risk and much more confidence with numbers
Even if you already understand LOPA you will benefit from the insights this course offers.
Definitely worth it for engineers who participate in HazOps and SIL assessments.
Its an excellent overview and practical course.
Excellent. Am going back from the training with a better understanding of how LOPA works and enthusiasm to facilitate one.
It's a great course
Course delivery was excellent and real world examples made the course much more enjoyable.
