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:
- Understand the power of HAZOP
- Identify when to apply HAZOP
- Understand the HAZOP guideword method
- Understand the human and engineering data resources required
- Be able to plan and report a HAZOP study
- Contribute more effectively at HAZOP study meetings
