Gas Turbine Component Overhaul & Repair

Due to the intense operating conditions that the engines are put through, a complete overhaul and repair service for the gas generators is provided, including where necessary, lease engines/ service exchange support. All repair activity schemes are carried out in our extensive workshop that has the latest overhaul facilities, overseen by our highly experienced team of inspectors, with the Gas Turbine Engines being tested and scrutinised at Score Energy Wellbank site, Scotland.

Heavy Investments have been made in the most up to date tooling and measuring equipment to ensure each task is done correctly. To prolong the life of the Turbine Engines protective treatments and special coatings are applied. To support these activities, Hycrome's state of the art advanced CNC Manufacturing facility allows clients the option to purchase not only a repaired product but a re-engineered new part.
