GAS TURBINE ROTOR LIFE MANAGEMENT AND EXTENSION
Preparing for the future
As your plant ages, a longer planning horizon creates both 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.
The history of GE’s B, E, and F fleets dates back over a half century. For the 7F alone, since 1990, there have been over 30 turbine rotor modifications, more than 10 compressor rotor enhancements, and more than 100 different blade changes. As the OEM, GE knows exactly what’s in your machine, and more importantly, which version of rotor it can be replaced with. We have developed proprietary gas turbine rotor manufacturing processes that cannot be duplicated by other providers, to make rotors through years of fleet and engineering analysis.
Operators of GE assets agree, and as rotor assets have aged over the last few years, customers have partnered with GE to replace more than 150 B and E turbine rotors and 200 7F rotors. 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.
FIND THE RIGHT SOLUTION FOR YOUR PLANT
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.

Multiple options are available for power and gas turbine rotor efficiency upgrades. For example, upgrading to a new 7F Advanced Compressor and 3-step aged turbine rotor will provide significant hot day MW (up to 20%) and heat rate improvement (up to 3%), operational flexibility, and maintenance reductions with field-replaceable blades. This compressor platform forms the backbone of GE’s latest generation of heavy-duty gas turbines, including the 7F.05 and HA portfolio. The B and E fleet offers a variety of performance and flexibility upgrades as well, including the 6F AGP .01 to .03 compressor upgrade, the 7E high flow compressor, the 9E AGP or 9E MAX, or a turbine module or F2F upgrade with the same footprint as the 9E.03.

Rotors are designed to operate at extremely high stress and temperature conditions—resulting in a finite operational life span. Our rotor life extension solution targets the repair, replacement and maintenance of individual gas turbine rotor components after a full disassembly and inspection protocol. It’s a cost-effective way to improve long-term reliability while continuing to realize operational value—when other options may not make economic sense. We draw on our field experience and accumulated OEM knowledge to create a customized life extension solution for gas turbine rotor assets that allows for extended operation of two or more additional maintenance intervals.
