CHASE offer steam turbine repairs for full turbines or components for the Power Generation and Process industry throughout the world. Main areas of expertise are the refurbishment of rotating blades, nozzles and diaphragms which have suffered from erosion or in service damage. Our methods of repair can be carried out either at our fully equipped workshop or at your site.

Steam turbines may require maintenance, repair or upgrades for a variety of reasons; planned maintenance, unplanned outages, reliability issues, or the need for improved performance.

EthosEnergy is our partner with which we offer these services.

EthosEnergy’s work is carried out to Civil Aviation Authority Standards and they have a quality procedure for every single operation from unpacking of goods to inspection and weld procedures. This procedure allows for full traceability including which operators have worked on each component. All welding is to ASMI and European standards and each weld is x-rayed to ensure no deformities. The result of this rigorous quality procedure is that EthosEnergy has never had a weld/blade failure in over 30 years of business.

Unique to the industry is our ability to carry out refurbishment to Low Pressure last stages of rotating blades without removal of blades from the rotor disc. Approval for our services has been gained from the original manufacturers, providing future validation of our quality, workmanship and specialist skills. Reduction in downtime, flexibility to suit customer demands and extension of the component life ensures customer satisfaction and substantial cost savings.
