Hazard and Operability (HAZOP) study

A Hazard and Operability (HAZOP) study is a procedure for verifying the safety and operability of a design. A series of expected ‘deviations’ are assessed in a brainstorming session. The term ‘deviation’ is used for changes expected from normal conditions for which the process/system was designed. Process conditions can change over time because of changing chemistry and/or other reasons. These factors should also be considered along with transient operations like startup, shutdown and emergency operations.

Our process safety experts also facilitate Procedural HAZOP to review the adequacy of procedural and design controls to ensure correct sequencing, early feedback of potential errors, clarity and completeness of transient operations. We also facilitate Pre-Startup Safety Review (PSSR) and other PHA studies like What-If and HAZID.
