Shared Components for SIS & BPCS – not a good idea

Recording Date: April 2021

The webinar addresses the problems relating to the problems of sharing components between the Safety Instrumented Systems (SIS) and Basic Process Control System (BPCS). The webinar highlights the impact on reliability and the need to perform an analysis on the contribution to the dangerous failure of the common cause failure, to ensure it is sufficiently low and within acceptable norms.

The webinar introduces the concept of the common cause factor (Beta) and the impact this has on shared or redundant components of SIS and BPCS. It explores some examples of the impact on PFDavg and how this can be compounded by also assuming perfect proof testing.
