Services - Maintenance template for Safety Instrumented Function (SIF)
Like any other equipment item, SIF risk is dynamic in an operating process facility. With the risk of hidden failures the challenge is to maintain the SIL rating (identified for a SIF) during O&M phase. Based on the unavailability target, test frequency needs to be re-calculated and adjusted. In a facility with several SIFs, this demands a disciplined documentation & SIF maintenance procedure. AGT is well placed to prepare maintenance templates for individual SIFs for monitoring & maintenance purposes.
