Layer of Protection Analysis (LOPA)

Topic Safety

CPD Hours 11.5

Price IChemE member £720 + VAT, non-member £864 + VAT

Overview

Live online course – starts on 15 July 2020.

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 online 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 virtual workshops, including the use of software tools. Course materials also include a compendium of LOPA research papers, reference materials and further reading.

Teaching will be delivered via two live modules (approximately three hours in length each), alongside independent study and pre-recorded video sessions issued before/between modules.

An e-certificate will be issued at the end of the course to confirm attendance and CPD hours logged.

Learning outcomes

By the end of this course you will understand:

  • the LOPA methodology and its application
  • 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

Ken Patterson

Originally an industrial chemist with experience of both lab work and plant operation, Ken joined HSE in 1986 as a specialist inspector, dealing with process safety. He worked as a field inspector across the North of England and spent periods in HSE headquarters, in major hazards and operational research.  He moved to Hickson & Welch in 1994, after the company’s major accident, as their Health and Safety Manager. He recently retired from Synthomer plc, an international polymer group with 20 manufacturing sites from the UK to Vietnam, where he was Group Risk and SHE manager.

Ken was a member of the working group which wrote IChemE’s “Fundamentals of Process Safety” course and has taught the course a number of times. He chaired the working group which produced the revised third edition of the CIA’s Occupied Buildings guidance and is a member of the UK Chemical Weapons Convention Advisory Committee. In 2012 he was awarded the Franklin Medal by IChemE for his work in process safety.
