HAZOP/SIF Review - SIL Assignment

IEC 61511 and ANSI/ISA S84.01-2003, as well as Regulatory Agencies, require that a process hazard analysis (PHA) be performed to identify potential hazards in the operation of a process unit.

The process design drawings, together with the P&ID’s and the PHA documents, form the basis for the identification of the safety instrumented functions (SIF) required to mitigate the potential hazards.

Premier Consulting Services provides industry experts in the review process of the PHA results and allocation of Safety Instrumented Functions (SIF), leading to the assignment of a target Safety Integrity Level (SIL) for each SIF.

A PCS senior consultant performs the role of facilitator and provides guidance to a multidisciplinary team consisting of plant experts in the areas of process, operations, safety, maintenance, instrumentation and electrical. PCS provides further guidance in the approach to aligning the SIL assignment method selected with the corporate risk tolerance criteria.

SILassign™ software tool-set is made available for the target SIL determination process.

Premier Consulting Services (PCS) reports are recognized world wide for their integrity and professionalism by plant operators, regulators and risk insurers.
