Layers of Protection Analysis: Practical Application and Pitfalls (LOPA)

Book Course

HSL is to run a 2 day course on Layers of Protection Analysis: Practical Application and Pitfalls (LOPA).

21-22 March 2018

Introduction

Layers Of Protection Analysis (LOPA) is a risk assessment method used to determine and hence demonstrate the ability of existing and proposed safeguards to protect against identified hazard scenarios and to meet predetermined risk based criteria.

The Process Safety Leadership Group (PSLG) prepared specific guidance for the applications of LOPA to determine the required safety integrity level (SIL) for overfill protection of highly flammable fuel storage tanks at sites similar to Buncefield. The course presenter was a member of the PSLG LOPA working group that developed the LOPA guidance. This course will draw on that guidance, its relevance to LOPA assessment in general, and pitfalls identified during the assessment of a large number of LOPA studies from the petrochemical industry.


The course will cover:

  • LOPA, uses and complexity
  • When to use LOPA and when to consider QRA
  • LOPA study prerequisites and preparation?
  • LOPA target frequencies
  • Human Factors
  • Input data sources and uncertainty
  • How to perform LOPA; LOPA rules and IEC 61511 requirements, scenario's, conditional modifiers, enabling events, Independent protection/mitigation layers
  • LOPA Outcomes; regulator expectations, ALARP considerations
  • Example pitfalls associated with LOPA
  • Case study examples

Who should attend

The course is aimed at those engineers, managers and safety professionals who have a basic knowledge of risk assessment possibly gained through HAZOP studies and PHA studies, who would like to have an understanding of the LOPA method and how to apply LOPA and the pitfalls commonly associated with this type of analysis.


For example typical attendees could be:

  • SHE managers
  • Engineering Managers
  • Operations personnel
  • Engineers - Safety, EC&I, Process, Electrical and Mechanical


Course presenter

Dr Colin Chambers CEng MIET has 15 years experience at HSL, initially on the development of risk assessment methods for the assessment of safety related systems such as the SIL determination method in informative annex of BS EN 62061 and 11 years experience of risk assessment within HSL/HSE and as a COMAH technical assessor. Dr Chambers was a member of the PSLG working group that developed the PSLG LOPA guidance and was part of the CA team charged with assessing post Buncefield LOPA studies

Dr Chambers has written peer reviewed papers and HSE reports on issues associated with LOPA and given numerous presentations at venues in the UK and in Europe.


Venue

The course will be run at the HSL laboratory in the spa town of Buxton. Buxton is in the heart of the Peak District and has good links to mainline train stations and Manchester International Airport.

Cost

The cost of this course is £1100 per person (includes course notes, lunch and refreshments).
