Our experienced safety team provides Safety Hazard Identification services to both our own facilities and a range of UK customers. Our expertise covers all stages of the plant lifecycle, from design through to operation, existing plant modification, and decommissioning. Techniques applied include Hazard and Operability Studies (HAZOP) and Failure Modes and Effects Analysis (FMEA).
We apply the HAZOP technique for 'identifying potential hazards and operability problems' caused by 'deviations from the design intent' on both new and existing process plants. This technique is used on both continuous and batch process systems and can be applied to a range of chemical and nuclear facilities.
At NNL, we also offer both a HAZOP leader and/or secretary. They support study teams that include the designers, safety representatives, members who have expertise in a range of related fields and people with a knowledge of operating similar equipment and plant. Our service also facilitates in-house teams from the initial stages of a project, including the selection of appropriate methods, through to action completion and close out.
For new plant the design, the process generally includes a number of HAZOP studies (HAZOP 0/1 & 2).
We generally base the first (HAZOP 0/1) study on the design specification and the resulting process flow diagrams / block diagrams.
The more in depth (HAZOP 2) study is based on the design specification, along with the more detailed Engineering Line Diagram and general arrangement drawings.
Our team can provide Failure modes and effects analysis (FMEA) - a step-by-step approach for identifying all possible failures in a design or process. Our safety assessment experts can then provide analysis of the consequences resulting from any failures.
