Tiger: Continuous Diagnosis of Gas Turbines

Robert Milne, Charlie Nicol

The TIGER system is in continuous use on 20 gas turbines across four continents. Continuously performing fault diagnosis of industrial gas turbines used for power generation. TIGER receives several hundred data inputs at a once per second interval and performs several layers of fault detection and diagnosis using expert system techniques in a temporal reasoning rulebase. Development of the system has now extended for more than six years and more than 80 man-years. The diagnostics are supported by an extensive user interface, data archive, trending and display system. Across the 20 current locations, TIGER has helped to identify and diagnose over 700 incidents representing 200 different fault categories. Because of the high value of gas turbines and the high expenses in operating them, TIGER's benefit is considerable and has been documented at $150,000 or more for many of the locations.
