Gas turbine rotor life management and extension
The history of GE’s B, E, and F fleets dates back over a half century. As the OEM, GE knows exactly what’s in your gas turbine—and which version of rotor can replace it.
Our history
Gas turbine rotor OEM expertise and experience
When it comes to rotor life management and extension, GE has the advantage. Our OEM knowledge, analysis of gas turbine rotor behavior, and site-specific operating conditions help us determine full residual part life capabilities. GE has the knowledge, history, and expertise to perform a full rotor life assessment, addressing all phases of the lifecycle—for today and tomorrow.
Our service center experts can perform a complete rotor tear-down, including cleaning and inspection of all safety-critical areas of the rotor wheels and shafts.
Rotors that have undergone GE’s rotor life extension process include the latest technology improvements and are certified for continued safe operation.
Our technologies include eddy current testing, ultra-sonic testing, and magnetic particle/fluorescent penetrant inspection.
Benefits
Gas turbine rotor OEM expertise and experience
For the 7F gas turbine there have been over 30 turbine rotor modifications, more than 10 compressor rotor enhancements, and more than 100 different blade changes since 1990. When it comes to addressing gas turbine rotor needs there are many different solutions, but GE has the knowledge, history, and expertise to perform a full rotor life assessment, addressing all phases of the lifecycle—for today and tomorrow.
Proven gas turbine rotor life management
Through years of fleet and engineering analysis, we have developed proprietary gas turbine rotor manufacturing processes that cannot be duplicated. As rotor assets have aged over the last few years, our customers have worked with us to replace more than 250 B and E turbine rotors and over 500 F turbine rotors. For the 7F gas turbine there have been more than 30 turbine rotor modifications, 10+ compressor rotor enhancements, and more than 100 different blade changes since 1990.
Planning ahead
Schedule your rotor life maintenance ahead of time
Your rotor is the driving force behind your gas turbine equipment, so it’s important to make sure it will continue to run reliably and efficiently. The energy industry is changing rapidly, requiring plants to cycle in new and different ways to address the increase of renewable power. These shifts are placing ever-increasing stress on all power plant equipment, and rotors are no exception. With many power plants now nearing the end of their operating capacity, it’s more important than ever to reach out to GE at least 3 to 5 years ahead of your planned outage to address your gas turbine rotor needs.

The remaining life after reconditioning depends on the consumed life (mainly starts) of the compressor section.
This solution is compatible with the following gas turbine types:

Frequently asked questions
Learn more about rotor life management
Rotor life management
What goes into rotor life management?
GE’s rotor life management strategy consists of 3 pillars: Analytical assessments, operational experiences, and variation sources. Analytical assessments are performed with computer models to better understand the physics associated with rotor lifing. Operational experiences refer to how the unit runs in its environment – for example, the number of hours and starts coupled with our findings in the services shops. Variation sources are other factors that can change the maintenance recommendations for the rotor, such as corrosion or running in a corrosive environment. As the F fleet continues to run, our lifing recommendations continue to be correlated with fleet experience, and we’ve developed inspections and repairs accordingly.
Rotor corrosion
What is rotor corrosion and how does it impact my rotor?
Corrosion is a natural process that causes the degradation of material and its properties. It’s caused by environmental factors that can allow contaminants to get into the gas turbine from the air, water or fuel. Airborne contaminants can be introduced in conditions like coastal or off-shore climates. Water can also cause corrosion if not properly treated per GE specifications. Fuels should also be managed properly to avoid corrosion in the hot section of the gas turbine.
What can you do? First, make sure your filterhouse and inlet are consistent with your ambient environment conditions and GE recommendations. If you see corrosion during outages consider upgrading your filters. You should also adhere to fuel or water specifications and follow inspection recommendations.
Rotor life extension
How to choose between start- or hours-based extension?
Rotor life extension
Tom Freeman, Chief Consultant for GE Gas Power, takes a look at one option power plants have to address rotor life: rotor life extension.
Rotor life and risk
How does changing operating conditions impact your rotor life and risk?
Rotor life and risk
Penny Leahy, F-class Rotors Product Manager for GE Gas Power, explores the many solutions you have to address rotor risk and maintenance.
Turbine rotor configuration and using nickel-based alloy wheels
Why is it important to use wheels that have been properly forged, machined and processed?
Using wheels that have not been manufactured and properly processed can result in forced downtime, longer outages, and performance and emissions issues. The process to create rotor wheels is extremely complex and has been developed by GE and our suppliers over 50 years. GE has millions of operating hours on its nickel-based alloy wheels, and based on lessons learned and proprietary analysis, we have made more than 30 design modifications to the 7FA gas turbine rotor. This vast experience, coupled with design analytics and inspection data, have given us a full understanding of the capability of these wheels.
Compressor rotor and understanding configurations, clearances, and performance
Why is configuration management important when installing GE’s compressor packages on my 7F gas turbine?
GE has developed our compressor packages with full instrumented testing, coupled with design analytics and fleet operating experience. In addition, we have made 10 compressor rotor design changes and hundreds of blade design changes on the 7FA gas turbine over the past 30 years, so we have a comprehensive understanding of the configuration. When configuration is not fully analyzed by GE engineering, errors can be made that result in outage delays of several months and performance losses of more than 5 MW.
Specialized inspection processes and tooling
Why is it important to use a qualified inspection process during rotor life management?
GE’s inspection criteria is defined based on years of analytical modeling and inspection data in shops or in the field. Addressing inspection findings requires engineering knowledge of the rotor system, and inspecting equipment also requires calibration and maintenance. GE has completed thousands of 7FA gas turbine inspections both in the shop and in the field.
