LOPA and SIL Determination Training Course

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).

LOPA Training Course

 

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 CCPS concept book “Layer of Protection Analysis – Simplified Risk Assessment”.

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.
