HAZID and HAZOPs

 

Hazard Identification (HAZID) and Hazard and Operability (HAZOP) studies form the basis of any risk assessment and an important understanding of potential hazards, possible causes, an assessment of the effectiveness of any safeguards already in place, and identification of possible hazard and risk reduction measures.

 

Experience has shown that HAZID and HAZOP are best carried out in a multi-functional and multi-disciplinary team review format with an independent chair, responsible engineers and operational personnel, relevant specialists and our key management.team has chaired many HAZIDs from offshore operations, including offshore construction activities, marine operations, new pipeline designs, decommissioning and novel applications such as a walk to work vessel operating in close proximity to a floating production, storage and offloading (FPSO) vessel.

 

The Windsor Consulting Group, Inc. also chaired a number of HAZOPs, including subsea wells, manifolds, flowlines and risers, FPSO topsides process and utility systems, FPSO marine systems and steam boiler / power generation packages, and unusual HAZOPs such as of a flexible riser annulus vent monitoring system. Our management team has also chaired an "End to End" HAZOP to review an entire project's multiple HAZOP studies to identify any omissions or inconsistencies at interfaces.Anatec has also reviewed and signed-off HAZOP action responses and collated HAZOP action close-out reports.

 

The HAZID and HAZOP methodology follows best practice including BS EN ISO 17776:2002: Petroleum and natural gas industries - Offshore production installations - Guidance on tools and techniques for hazard identification and risk assessment, and HAZOP - Guide to Best Practice, I Chem E, 2008.

 

HAZID

The Hazard Identification (HAZID) is a high level review of potential hazards, based on checklists. The Windsor Consulting Group's  “HAZCHEK” proprietary checklists have been developed after years of experience and cover facility siting, human factors and best engineering practices. HAZID is the first step in primary risk assessment for a new facility and key in the risk governance process.

HAZOP

Hazard and Operability (HAZOP) study for continuous or batch processes, or procedural operations is an excellent tool to identify potential hazards and operability issues and recommending preventive actions. Our expertise facilitates HAZOP studies in the role of HAZOP team leader and ensures that the HAZOP study identifies the following:

 

1. The hazards of the process 

2. The identification of any previous incident which had a likely potential for catastrophic consequences in the workplace

3. Engineering and administrative controls 

4. Consequences of failure of engineering and administrative controls

5. Facility siting

6. Human factors and

7. A qualitative evaluation of a range of the possible safety and health effects of failure of controls on employees in the workplace.

 

A good HAZOP study is also used as an input for proceeding with Layers of Protection Analysis. It must be remembered that a good HAZOP study is only as good as the skills of the facilitator and team members. The Windsor Consulting Group's technical expertise and human factor approach to HAZOP studies helps to maximize the output of the HAZOP team.
