This technical briefing is offered for public live-streamed delivery. It is also available for in-house live-streamed delivery.


Hazard and Operability (HAZOP) studies are performed by companies to manage process risks. A key aspect of these studies is the subdivision of the process into sections, or nodes, for study. Proper node assignment helps to avoid omitting scenarios from studies, complicating the work of the study team, and spending more time than necessary performing a study.

This technical briefing provides guidelines for assigning nodes so that these problems can be avoided. It is intended for practitioners who are new to HAZOP studies and those who need a refresher on the latest approaches. Attendees receive an electronic copy of the technical briefing materials.

What you will learn:

  • How to choose an optimal number of nodes
  • How design intent influences node assignment
  • What not to node
  • Importance of global nodes
  • Guidelines for assigning nodes
