Overview

"All of a sudden, the whole concept came together as an 'aha'." 

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.

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 also include a compendium of LOPA research papers, reference materials and further reading.

This course is also delivered online with different start times to suit participants from around the world.

Learning outcomes

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

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

Previous delegates said

100% of recent delegates (in the UK) had their learning objectives met and said they would recommend the course to their colleagues due to the:

  • clear explanation of the LOPA process combined with worked examples to demonstrate its application
  • experienced trainers able to put requirements into context
  • practical exercises and real-life examples/case studies
  • detailed course materials.

"Exactly the required information for me to carry out LOPA activities."
Philip Gow, Mexichem, UK

"I found the real-life examples very useful to aid understanding."

Louise has deep technical expertise developed through extensive experience within operating companies. She has worked in both process and process safety roles upstream onshore and offshore in oil and gas facilities, from drilling and completions to the export pipeline and oil and gas processing. 

She joined BP Sunbury, UK in the Major Accident Hazards team after an internship with them before her final year at Imperial College, and subsequently secured two offshore support roles. In 2012, she moved over to support the wells organisation as one of the first process safety engineers in this team. In 2013, she joined the Shell Aberdeen projects team as a technical safety engineer working on several brownfield projects through the Shell risk management processes. A year later, she moved to Dubai to support the Majnoon field (one of Shell's Iraq assets) and quickly became the technical safety tteam lead for the venture. In 2018, Louise moved to the Norwegian project team to head up the process safety team.

In 2019, Louise set up Barberton Limited which provides risk management solutions for a variety of businesses. Louise is passionate about education from preschool to workplace and is involved in a range of activities including governor of her local primary school, STEM ambassador, guest lecturing at Imperial College, facilitator for technical courses at IChemE and an educational series for the Safety and Reliability Society (SaRs).
