Operator / OEM Collaboration on Trip & Alarm Rationalization
MetadataShow full item record
Turbomachinery has increased in complexity and monitoring capabilities over the last several decades. This has resulted in an increased number of trips to protect various machinery systems. The prevailing OEM philosophy has been to protect the machine assuming that an immediate trip is safer and results in the lowest financial consequences. ExxonMobil and Siemens collaborated to redesign machinery protection and control systems with an “Operator’s mindset” – considering the integrated, full plant risk. The goal was to maximize safety and minimize integrated risk resulting in an increase in mean time between forced outage (MTBFO).
