Reliability Upgrades
Not all severely damaged rotors require replacement, regardless of common recommendations from OEMs.
Most of the damaged rotors are repairable. Bent rotors represent one group of damaged equipment which EthosEnergy repairs on a daily basis. Rotor straightening allows a reduction in downtime, reduction of costs, and removes stresses within the rotor. It is an advantageous alternative against purchasing new rotors. The biggest distortion (bend, run-out) repaired successfully by EthosEnergy is 5.40mm. Rotors that bend at several planes also qualify for rotor straightening. The level of EthosEnergy knowledge and experience within straightening allows us to guarantee 0.12 – 0.05mm run out post straightening process. We can restore the turbine rotor to its OEM condition in a much shorter cycle time than other providers. Rotors that are subjected to straightening are back in full operation after repair.
