The Design Service Life of a gas turbine rotor can be based on statistical predictions of component life, based on an assumed operational mission mix; each rotor component is influenced differently by operational stresses, temperatures, and duty cycles. We look at the Gas Turbine Rotor and Compressor Rotor. A Rotor Life Extension service can help decide if component repair, replacement, or use is the best option for your gas turbine rotor to meet operational and maintenance forecasts. MD&A’s Gas Turbine Rotor Life Extension Program provides options for your aging fleet. Our goal is to meet your operating strategy for remaining life through validation, repair, or replacement of life-limiting components.
