8. After completing the HAZOP analysis, can the quality of this analysis be measured by the percentage of recommendations that are adopted by the client (or users within the company)?
The \"Guidelines for the Application of Hazard and Operability Analysis (HAZOP Analysis)\」(AO/T3049-2013) divide the HAZOP analysis process into two approaches: element-driven and trigger-word driven*. A component refers to a part that makes up a node; for example, a node may include storage tanks, pumps, reactors, etc., and the storage tank is one such component. When element priority is considered, select the \"tank\" as the analysis element, and then choose different types of deviations (such as excessive temperature, excessive pressure, excessive liquid level) to analyze it. When priority is given to guiding words, select a guiding word such as “pressure”, and analyze separately the consequences of “excess pressure” and “low pressure” for components in the node such as storage tanks, pumps, reactors, etc.
Time should be planned properly for HAZOP analysis, and thorough preparations must be made before the analysis meetings. These meetings should not be held continuously, as this can lead to fatigue among the participants and omissions in the analysis. For projects with complex process flows, it is advisable to hold meetings 2–3 times per week; it is important to keep good records of the analyses. To accelerate the progress of these meetings, the project can involve multiple analysis teams working simultaneously, or recordings of the meetings can be used to reduce the time required by those responsible for taking notes on site.
