Layer of Protection Analysis (LOPA)

Topic Process safety

CPD Hours 11.5

Online | Face-to-face | In-company

Overview

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.

Responsibilities and challenges

Learning outcomes

By the end of the course you will understand:

the LOPA methodology and how to apply it
how to decide if a process needs a safety instrumented system (SIS)
what safety integrity level (SIL) is required
how to define an Independent Protection Layer (IPL)
how to implement a process to manage these systems through the life cycle of an installation
how to lead a LOPA study.
