What is a HAZOP?

A HAZOP is a highly structured hazards identification tool. It is extremely basic in its approach and makes practically no assumptions.

When should you use HAZOP?

HAZOP methodology is so widely used that almost any PHA is also referred to as a HAZOP. With new designs, HAZOP’s should be carried out as late as possible in order for it to be as complete as possible. With an existing facility, the HAZOP can be used at any time.

You can also use a HAZOP for analyzing operating instructions, procedures and in batch operations.

HAZOP Methodology

1. Collect applicable documents and drawings.
2. Break facility into manageable sections (Nodes).
3. Prepare list of Parameters and Operations to be examined.
4. For each Node create Deviations.
5. List and record causes for each Deviation.
6. List and record Consequences for each Cause.
7. List and record Safeguards or Controls that may prevent either the Cause or the Consequence.
8. List any future Actions or recommendations you think should be implemented.

HAZOP Study Facilitation

Dyadem's Engineering Services Division offers a proven track record of helping our clients achieve success in risk mitigation and is committed to providing industry professionals with constructive solutions to facilitate their Hazard and Operability (HAZOP) Studies. Dyadem can provide the resources that you need to complement your existing project team. We will review the project and its goals at the beginning of the project to ensure that it provides the information, analysis and solutions that meet your needs.

Dyadem facilitates your HAZOP study in a three-step manner. We will first review the respective process safety information along with the scope and objectives of the project. This is followed by a series of onsite meetings where the facilitator guides the team to identify the hazards associated and assists them in analyzing these scenarios further. Post meeting, the facilitator provides a report that includes all the findings and recommendations of this study.
