Aftermarket, Repairs, and Overhaul Market with EthosEnergy

Turbomachinery International visited one of EthosEnergy’s Houston-based facilities: the light gas turbine workshop and performance center. During our tour, we spoke with Philip Booth, the Engineering Manager at EthosEnergy’s light turbine facility. He shares the changes he’s seen in the past several years in the repair and overhaul market and the impacts decarbonization has had on aftermarket repairs.

Q: What changes have you seen over the past 5 – 10 years in aftermarket repair/overhaul? What trends are you seeing?

Booth: From an engineering point of view, we are increasingly seeing customers looking to aftermarket for our technical and engineering expertise. We answer questions about the turbines, yes, but increasingly [it’s about] balancing their plant—trying to support the customers, optimize the efficiency and effectiveness of their plant, extend the time between overhauls to bring down lifecycle costs.

Q: How has decarbonization impacted, if at all, aftermarket repairs?

Booth: We've seen this two ways: The obvious one is as emission limits have dropped, OEMs have responded accordingly, developing new technologies. In the aftermarket, we've had to respond to that, so we're quite comfortable overhauling and testing all the technologies—conventionally fired units or wet NOx abatement engines—but increasingly we can test and overhaul right up to the sub 10 PPM NOx engines. So, we're comfortable supporting the most advanced technologies in the workshop.

Second, it's more about the life of the equipment—people are much more inclined to try to extend that as long as possible, so we have a repair-centric methodology for the overhaul process. We work with our other businesses in the Ethos network to develop advanced repair technologies, such as a part that would’ve been thrown away years ago, we're repairing and making sure it still has its effectiveness so that it's good for another four to five years of operation.
