HAZOP study is rigorous, multidiscipline method to check P&ID’s using guide words and parameters to identify the possible causes and effects of potential hazards, and to identify design efficient features to mitigate potentially hazardous conditions by analyzing all possible deviation from the design intent. SIL determination is the activity for reviewing whether specific SIS protection layer is needed to achieve the required SIL (Safety Integrity Level) or not. By appropriate HAZOP discussion and proper recording considering SIL process, the combination concept of HAZOP and SIL determination study shall give 1) minimizing the over or under SIL level, 2) maintaining the consistency, and 3) getting more discussion time within given schedule. |
