Course Overview

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 should attend

This course will be beneficial for production engineers, process design engineers, project engineers as well as instrument control designers.

Trainer Profile

Nigel Bowker BSc(Eng), ACGI, MBA, C Eng, FIChemE

After graduating from Imperial College in 1976 with a degree in chemical engineering, Nigel worked as a process engineer for two firms of design contractors (Stone and Webster and Davy Powergas) and later worked for Shell Expro.

In 1986, he joined BP where he worked for the next 22 years. His career with BP included exploration and field development, production operations offshore (in Forties) and onshore (in the Forties Pipeline System), internal audit and health, safety and environment. His final role was as HS&E Manager in supply chain management for the North Sea.

After taking early retirement from BP, Nigel set up his own consultancy. He has provided a range of services to clients including process engineering, audit, process safety and occupational safety. He now specializes in chairing HAZIDs and HAZOPs and is an accredited HAZOP chairman with BP.

Nigel is a fellow of the Institution of Chemical Engineers and is a former chairman of the IChemE’s Aberdeen Member Group.
