One area of confusion for many clients is in understanding their requirements for existing Safety Instrumented Systems (SIS) that were not designed in accordance with IEC 61511 (i.e. Legacy Systems).
FSES can review the existing system and identify any areas for improvement to demonstrate compliance with the “Spirit” of IEC 61511. We have considerable experience in this area and provide practical solutions with a focus on applying appropriate levels of rigour.
