Process and Safety > Layer of Protection Analysis (LOPA) - Virtual Instructor Led Training (VILT)

About this Virtual Instructor Led Training (VILT) 

As a result of major incidents such as the Buncefield storage depot explosion in the UK, it is now expected that achieving tolerable risk is justified by a rigorous method. The method – Layer of Protection Analysis (LOPA) – will assist organisations with the analysis and assessment of identified process plant hazards.

This method can answer key questions like ‘Do we have enough controls?’ or ‘Are they sufficiently effective?’ It is often used as a follow-up to a HAZOP study to confirm the qualitative judgement and decisions made by the team. It is considered to be a semi-quantitative technique since it uses ‘order of magnitude’ estimates of risk reduction of each protection layer and is therefore less time-consuming than using Fully Quantified Risk Analysis (QRA).

This 4 half-day Virtual Instructor Led Training (VILT) course will equip participants with an understanding of how a hazard scenario is defined and its severity is categorised to set a tolerable frequency. Participants will learn to determine how many Independent Protection Layers (IPL) are required to achieve the tolerable frequency, and how to specify an IPL.

All of these activities are covered by a tutored exercise and group work. Only simple numeracy skills with an understanding of scientific notation, for example, one in a thousand expressed as 1.0E-03, are required. The VILT course materials will include a copy of the presentation slides, comprehensive notes and recommended further reading. Teaching will be delivered via four VILT sessions at 4 hours per session, with informative videos and plenty of opportunity to ask questions.

By the end of this VILT course, participants will have an understanding of:

  • The role of LOPA in technical risk management
  • LOPA methodology and its application
  • When to use LOPA
  • What Safety Integrity Level (SIL) is required for a hazard scenario
  • How to define an Independent Protection Layer (IPL)
  • The lifecycle process of Functional Safety

and they will be able to:

  • Use SIL determination to screen out low risk scenarios
  • Apply the LOPA methodology in real situations
  • Lead a LOPA workshop and report its findings
  • Justify HAZOP recommendations using LOPA

This VILT course is intended for:

  • Those who are involved in process design including process safety, process design and instrument & control engineers
  • Those who are responsible for Technical Integrity assurance
  • Those who are required to lead a LOPA study
  • Those who are required to technically approve plant design and process safety improvements e.g. project engineers and plant managers.

The VILT course will be delivered online in 4 half-days consisting 4 hours per day, with 2 breaks of 15 minutes per day.

Course Duration: 4 half-day sessions, 4 hours per session (16 hours in total).
