CASE STUDY: SIS MANAGEMENT TRANSFORMED

The SIL-Solver report interface quickly shows users where projects stand green indicates completed work, yellow shows incomplete tasks, and grey represents work that has not started.

tion, ensuring accuracy and alignment from field operations to corporate safety audits. It was a paradigm shift — going from exchanging documents to exchanging data,” Muthiah says. “Suddenly, we could slice, dice and act on our safety insights.” The system enables Phillips 66 to compare SIL ratings across similar systems, standardize processes and ask deeper operational questions: Why does one refinery require more SIL 2 functions than another? Is the risk profile accurate or are assumptions misaligned? What about outlier data? With its SIS data structured and centralized, Phillips 66 is now uncov ering patterns that were previously hidden. Strategic alignment with industry direction The ongoing efforts to access, analyze and visualize SIS data in aggregate are helping Phillips 66 become increasingly proactive in its safety management. As this work progresses, their teams are beginning to identify systemic issues and risk clusters, moving beyond merely addressing isolated failures. “When you zoom out and leverage relevant data, you move beyond addressing isolated issues and start resolving the root causes within the entire system,” Muthiah adds. Phillips 66’s SIS digital transfor mation aligns with the Industry 4.0 Maturity Index developed by the National Academy of Science and
