Course Description:

HAZOP is a technique, which provides opportunities for people to let their imaginations go free and think of all possible ways in which hazards or operating problems might arise, but — to reduce the chance that something is missed — it is done in a systematic way, each pipeline and each sort of hazard is considered in turn. The study is carried out by a team so that the members can stimulate each other and build upon each other’s ideas.

Course Goal:

The aim of the course is to introduce hazard identification and develop a basic understanding of the Hazard and Operability Study technique by means of short presentations and a syndicate exercise. The syndicate exercise will be chosen to match the client’s activities.

Course Objective:

By the end of the workshop the participant will be able to:

1. Understand the power of HAZOP
2. Identify when to apply HAZOP
3. Understand the HAZOP guideword method
4. Understand the human and engineering data resources required
5. Be able to plan and report a HAZOP study
6. Contribute more effectively at HAZOP study meetings
