Hazard and Operability Analysis (HAZOP) is a semi-quantitative systematic and structured method used in simple or complex, both new and existing processing and production plants for detailed hazard identification and risk assessment. This occurs through the use of a reliability, availability, and maintainability (RAM) analysis that takes into account the probability of occurrence and consequence severity. Various categories of interest to clients– among those, individual, environmental, economic and reputational– are covered. Analyzing a project through the lens of HAZOP allows for thorough, subdivided investigation in order to assess the potential danger a given operation can cause to the system.

Pryxida TECH offers experienced HAZOP leaders who stimulate critical thinking among members of the panel so as to analyze different elements of design and operation. When having obtained and applied the according recommendations, the residual risk associated with each event is reduced to a degree satisfactory to the client.
