End of Life Evaluation

The Design Service Life, aka End of Life (EOL), of a gas turbine rotor can be based off 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. An EOL Evaluation can help decide if component Repair, Replace or Use is the best option for your gas turbine rotor to meet operational and maintenance forecasts.

"Think Beyond Limits" Solution

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, "Think Beyond Limits" solution may include:

• Life extension for additional intervals
• Extension through specific component repairs, replacements, upgrades, and/or modifications
• Rotor Exchange Program
• Rotor Replacement

MD&A’s San Antonio Service Center can extend the service life of gas turbine components whose OEM service limit has passed or whose configuration is no longer suitable to operate. Significant savings can be realized by opting for lower-cost repaired spares instead of new parts. Read 3 case studies here.
