HAZOP and SIL Audits and Studies

The HAZOP (HAZard and OPerability) method is a process technology analysis that can be used to implement risk assessment for envisaged and already operational systems. During such audits, process management units and equipment protection devices are given significant emphasis, furthermore, they take any personnel that may be present and their experience into consideration.

HAZOP and SIL (System Integrity Level) have the role of analysing the safety-related systems, solutions and processes in details. In addition to that, they study the operation of safety-related systems whenever any kind of malfunction occurs.
