An Introduction to LOPA

An Introduction to LOPA


£199.00 price excludes VAT


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. This course will help you develop a better understanding of all things LOPA.

The course will help you to understand the principles of a LOPA study, how to identify significant scenarios and how to define an independent Protection Layer, how to estimate frequencies and how to document and audit a LOPA study.

By the end of this course, you will understand:

  • the basic principles of the LOPA technique
  • how to develop a LOPA scenario
  • how to define the targeted frequencies
  • how to design independent protection layers (IPLs).
