Challenge: SIS testing required multiple resources and valuable time during an outage. This effort took multiple crews around the clock and the logic testing was typically critical path delaying start-up [What is SIS? It is a distinct, reliable system used to safeguard a process to prevent a catastrophic release of toxic, flammable, or explosive chemicals].
Solution: A couple of solutions were utilized in an effort to reduce the impact of SIS testing. A pm was setup to proof test redundantly configured devices on-line. In addition to on-line testing, an automated testing software was utilized in place of a paper procedure to validate the logic.
Results: Decreased man-power cost during outage and removed testing from critical path. Automated testing software improved repeatability, efficiency and quality of the testing.
Impact: $1 million in revenue and $0.5 million operational savings
