Performance measurements of critical turbomachinery are very important to ensure reliable plant operations. Downtime related to unavailable critical equipment can cost the facility millions of dollars in lost production and maintenance. Steam turbines are one group of the most important prime turbomachines used commonly within hydrocarbon processing facilities. Overhauling of steam turbines is normally done during major planned outages and generally warrants including the original equipment manufacturer’s (OEM’s) expertise. Accordingly, online performance monitoring and establishing performance indices (PIs) for steam turbines are crucial when optimizing equipment reliability an
