Also, like most operating companies, we use Process Historians to collect data about the performance of our processes â including our control and safeguard systems. We have begun using this Historian data to analyze the actual âreal-worldâ IEFs and performance of our Safety Instrumented Functions (SIFs) and other Independent Protection Layers (IPLs) in our processes. In this paper we will describe the results of one part of this work and how we are using the resulting data in four important ways: to indicate the real-time health of active risk management Safeguards; to integrate the learnings as Key Performance Indicators (KPIs); as inputs to our PHA/LOPA revalidations; and to help us comply with IEC61511/ISA-S84 for the Operation and Maintenance phase of the Safety Life Cycle.
