Proven and reliable end of life solutions for aging fleets, including heavy duty gas turbine frame B, E, and F class as well as mature Westinghouse units. EthosEnergy’s solutions have been engineered to meet or exceed the original equipment manufacturer and the recommended end of life.
Run your rotor for longer
There are more options than you might think when it comes to addressing your rotor end of life. Options beyond purchasing a new rotor, moving to a new technology, or risky used and grey market options.
You need a trusted partner to navigate these options.
Benefits of rotor life extension
There are significant advantages to staying in your current technology and choosing a rotor life extension over a change in frame type or technology, most notably cost efficiency and the carbon-friendly decision to reuse versus manufacture new.
EthosEnergy is the only non-OEM rotor option available for B/E/F class that uses OEM technology and materials. Key benefits include:
- Cost management
- Minimal turnaround time - no need for new permitting
- Flexibility vs rigid OEM offering
- Carbon-friendly (ESG friendly) by reusing existing assets vs new manufacture
About Rotor End of Life
A growing number of Frame3, Frame 5, Frame 6, Frame 7E/EA and Frame 9E units are approaching the designed end of life according to Technical Information Letter (TIL) 1576 from the OEM. The TIL outlines the risk associated with exceeding hours and starts limits, including:
- risk of failure and
- serious injury to nearby personnel.
You could also face a loss of insurance or denied claims by operating beyond these limits:
- 200,000 FFH
- 5,000 FFS
A growing number of Frame 6F, Frame 7F, and Frame 9F units are approaching the designed end of life according to Technical Information Letter (TIL) 1576 from the OEM. The TIL outlines the risk associated with exceeding hours and starts limits, including:
- risk of failure and
- serious injury to nearby personnel.
You could also face a loss of insurance or denied claims by operating beyond these limits:
- 144,000 FFH
- 5,000 FFS
Rotor Solutions
Lifetime assessment (LTA)
- TIL 1576 allows for a potential one-time extension beyond the FFH/FFS limits based on the results of an LTA. EthosEnergy’s qualified craftsmen and engineers can perform the LTA and determine the possible life extension based on results
Condition Based Life Extension (CBLE)
- our qualified engineers perform a detailed evaluation of the rotor condition, associated risks, and recommendations for component replacement with a possible 50k-200k FFH and 2,500 FFS extension
Phoenix Rotor™
- A hybrid rotor with new and Certified Previously Operated (CPO)™ components certified for the equivalent of the life of a new rotor. Proven OEM design and materials are used for EthosEnergy Phoenix Rotor™ compressor and turbine rotor discs.
Certified Previously Operated (CPO)™
- A rotor with a known pedigree that has been thoroughly inspected and tested at one of our centers of excellence. Certified for possible life up to 150k FFH and 2,500 FFS.
New Rotor
- Our manufacturing facility in Torino can manufacture EthosEnergy's upgraded rotor design that is interchangable with your current rotor.
Webinar on Rotor End of Life
This session will explore the design limits of your GE Gas Turbine Rotor as outlined in GE TIL 1576, outline critical factors to consider when deciding to replace or extend an end of life rotor, and provide details of EthosEnergy’s Rotor End of Life Program
OEM Pedigree with the flexibility of an ISP
OEM Pedigree with the flexibility of an ISP
EthosEnergy is the OEM for Fiat and Mature Westinghouse units, with over 65 years of OEM manufacturing experience. By applying our OEM design standards and processes, EthosEnergy manufactures combustion, gas path, compressor and rotor parts for these units as well as GE heavy frame gas turbines.
We have developed a suite of rotor solutions aimed at extending the life of your asset in compliance with OEM recommendations, allowing you to stay in your current frame type for longer without purchasing a newly manufactured rotor or changing technology.
Technical Overview
Using analytical tools and our OEM material database, we have identified the residual life of all rotor components.
We then re-engineered the critical components using stress, temperature, and finite element models, allowing us to understand cyclical and operating life and develop our rotor life extension solutions.
