Overview

Many facilities use Safety Instrumented Functions (SIFs) to reduce the likelihood of a hazardous event and maintain the As Low As Reasonably Practicable (ALARP) status. SIFs are generally designed and operated in conformance with IEC 61508/ 61511. The codes address SIF design, selection and ongoing management in terms of a lifecycle.

This two-day course will help you better understand all aspects of the SIF lifecycle, including how to determine the Safety Integrity Level rating for a SIF. The two most frequently used techniques (risk graphs and Layer Protection Analysis) for determining the required SIL are explained in the course. You will also learn about the most common pitfalls and how to overcome them. 

The course draws upon a range of exercises and case studies from different industry sectors.

Learning outcomes

  • the principles of the SIF lifecycle
  • how to determine the SIL (Safety Integrity Level) rating for a SIF, using both risk graphs and LOPA
  • how the SIL is verified
  • the ongoing management of SIFs, through operation, maintenance, modification and decommissioning

Who will benefit

Anyone who would like to develop a broad understanding of SIFs and their management, especially technical/process safety specialists.

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.
