Rotor Life Extension

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 & 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.

To provide the best solutions for your gas turbine rotor, MD&A evaluates your specific needs in addition to assessing rotor inspections:

Customer Inputs:

  • Unit and Rotor Operating History
  • Rotor Configuration and TIL status
  • Operating Forecast
  • Specific Concerns (Vibration Etc)
  • Business Goals
  • Financial Planning Current and Future
  • Schedule Considerations

Rotor Evaluation Inputs:

  • Advanced NDE Results
  • Metallurgical Evaluation
  • Material Hardness and Composition
  • Dimensional, Runout, and Balance Data
  • Configuration Assessment
  • Stress and Thermal Modeling
  • Complete Engineering Analysis

Based on a thorough engineering evaluation, the Rotor Life Extension options may include:

  • Extension through specific component repairs, replacements, upgrades, and/or modifications
  • Rotor Exchange Program
  • Rotor Replacement

Component Manufacturing: MD&A is a premier worldwide supplier of heavy-frame Gas Turbine Rotor components. As your fleet approaches rotor end of life, inquire about MD&A’s replacement turbine wheels, disks and spacers:
