HSEHAZOP is based on systematic risk assessment, which is a merit of HAZOP, and it is suggested that successful HSE engineering can be achieved through risk quantification and risk reduction using the safety integrity level (SIL). 2. Existing PHA Method The HAZOP and SIL are based on global standards (IEC 61882 for HAZOP and IEC 61511 for SIL).

The basis behind the HAZOP technique is that; a Hazard and Operability (HAZOP) study attempts to identify how a process may deviate from the design intent. In other words, a hazard is assumed to occur only if the process deviates from its design. The emphasis in the HAZOP study is on identifying potential hazards, not finding solutions to ...
