Overview

Learn the latest process risk assessment technique for process control

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 course covers the basic methodology of LOPA and the detailed stages of its application. Participants are shown how significant scenarios are identified and how frequencies are estimated for the worst-case events. All the essential steps in this method are practised in workshops, including the use of software tools in LOPA.

Learning outcomes

  • the basic methodology of LOPA
  • how to decide if a process needs a safety instrumented system (SIS)
  • what safety integrity level (SIL) it needs
  • 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

  • production engineers
  • process design engineers

Course presenter

Richard Gowland, consultant

Richard’s career started in the steel industry and later moved to project engineering in polyurethanes industry. He joined Dow Chemical in engineering function in 1971 and progressed from project engineer for major expansion in agricultural chemicals in 1975, to manufacturing management of large agricultural chemicals facility and control of contract manufacturing of new compounds until 1987, and then technology centre project manager responsible for new compound scale up at contract manufacturing until 1989. From 1989 to 2003 he worked in process safety management for Dow Europe and global leader for process safety technology for Dow Agrosciences and was member of policy and standards setting group. From 2003 to the current day he has been the Technical Director of European Process Safety Centre and chair of Buncefield PSLG group which produced HSE guidance on LOPA for Fuel Storage sites.

From 2003 onward Richard has also been an independent Process Safety Specialist with emphasis on LOPA.
