Why EthosEnergy?

Flexible, tailored solution from a partner to guide you through rotor replacement

Our history as an OEM for Fiat and Mature Westinghouse gas turbines combined with being an Independent Service Provider (ISP) allows us to offer both the manufacturing capability/quality/standards of an OEM and the commercial flexibility of an ISP. 

Over the last 15 years, we have focused on the rotor market and gained extensive experience in engineering, repair, and manufacturing of components for GE B, E, and F-class units. We have successfully developed a comprehensive rotor life extension program including new rotor manufacturing and custom life extension.

Fully compatible and interchangeable

Key to our re-engineering process was the necessity to have a design that was backward compatible with original designs.  After compiling our experience in the evolution of the rotor designs, we developed a short site checklist to confirm the version of the operating rotor. Our replacement designs mix the best improvements possible while maintaining the critical geometry for compatibility.

Improved design to address known weaknesses of original design

Our engineering team applied our OEM knowledge and experience to improve rotor designs. We developed a digital-twin model for each rotor in our portfolio.  The model identified original design weaknesses that were matched to the known industry issues. 

Our design chastresse validated in the model to improve resilience to stress. The digital twin is also a key tool in evaluating rotors for life extensions. Continued validation of the model occurs with each inspection for rotor life extension.

Technical specs

EthosEnergy 7FA.03 and 7FA.04 rotors are certified for the maximum life of 144,000 Factored Fired Hours (FFH) and 5,000 Factored Fired Starts (FFS).

The design has been improved upon by EthosEnergy’s experienced gas turbine engineering team. Our proven OEM design and superior alloys are used for EthosEnergy’s Frame 7FA.03/.04 compressor and turbine rotors.
