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 machine—and which version of rotor can replace it.
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. Our customers agree, and as rotor assets have aged over the last few years, they have worked with us to replace more than 150 B and E turbine rotors and 250 F turbine rotors. Customers that have worked with unqualified suppliers haven’t always been able to benefit from this OEM expertise.
GE’s rotor solutions
Gas turbine rotor life management and extension solutions
As your plant ages, a longer planning horizon creates more options to consider as well as time to assess and quantify risk. Changing generation patterns and operating demands, regulatory uncertainty, and increasing cost pressures all illustrate the need to cost-effectively manage and maintain gas turbine rotor assets to keep operating your fleet while reducing downtime for the long term.
Planning early not only allows you access to a wider array of rotor management options, it also helps you to get the most from your plant.

Rotor exchange with new rotor
Your goals
Prioritizing reliability and technical capabilities. You have a long-term planning horizon for your plant, but you’re also interested in reducing your total rotor costs.
Compatible gas turbines
GE: Fr5, 6B, 7E, 9E, 6F, 7F, 9F
Ex-Alstom: GT8, GT9, GT11, GT13, GT13E, GT13E2, GT24, GT26
Removing and replacing your existing gas turbine rotor with a new rotor from GE delivers enhanced reliability, advanced equipment, the latest materials, and enhanced performance to customers who plan to operate their facility over the life of the new rotor. It resets the clock on your rotor at 144,000 or 200,000 hours and 5,000 starts.
Rotor exchange with refurbished rotor
Your goals
Getting your rotor back to operation—FAST—with lower upfront costs, and greater flexibility.

Ex-Alstom: GT8, GT9, GT11, GT13
Our Rotor Exchange program provides you with a gas turbine rotor that has been inspected and if needed, improved to GE’s strict standards, with life still left on the asset. You receive a GE-certified rotor with the latest technology improvements. Best of all, you get it quickly, helping to reduce downtime, especially in emergent situations.
Rotor exchange with gas turbine uprate
Your goals
Lowering total rotor costs while improving plant output, efficiency, and flexibility.
Compatible gas turbines
GE: 6B, 7E, 9E, 6F, 7F, 9F
Multiple options are available for power and gas turbine rotor efficiency upgrades for customers interested in improving output and operational flexibility, while reducing maintenance.
RotorUp
Your goals
You’re looking for a rotor solution that is fully customized, with improved cash flow, flexibility, the latest technology improvements, cost avoidance, and continued modernization.
Compatible gas turbines
GE: 6B, 7E, 9E, 6F, 7F, 9F
Our RotorUp program delivers increased plant availability and reliability by transforming rotor life decisions into an adaptable asset rotor life management strategy. This program enables you to buy only the amount of rotor life needed for your plant. If things change in the future, it’s not a problem—this program is flexible over the life of your plant.
Rotor life extension
Your goals
Keeping your existing rotor because you have a flexible outage window and are looking for an economical solution. Additionally, you may have a spare rotor that can be used as a seed rotor to extend the life of a broader range of rotors.

Rotors are engineered to operate at extremely high stress and temperature conditions—resulting in a finite operational life span. Our rotor life extension solution targets the rotor balancing, repair, replacement, and maintenance of individual gas turbine rotor components after a full disassembly and inspection protocol. We can create a customized life extension solution for gas turbine rotor assets that allows for extended operation of two or more additional maintenance intervals.
