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.

Course outline

  • Concept, purpose and principles of LOPA
  • LOPA methodology (selecting scenarios, the LOPA process, describing scenarios, estimating initiating event frequencies, independent protection layers and their reliability)
  • LOPA study and documentation
  • Advanced aspects 
  • Facilitating a LOPA study
  • 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.

Who will benefit

  • Process safety engineers
  • Loss prevention specialists
  • Production engineers
  • Process design engineers
  • Project engineers
  • Process programmers
  • Instrument control designers
  • Anyone responsible for leading a LOPA study
