A research collaboration between Renewable Parts Ltd (RPL), SSE Renewables and the National Manufacturing Institute Scotland (NMIS) has demonstrated the potential to remanufacture critical onshore wind turbine components – restoring worn or damaged parts to their original specification or better. The outcomes could drastically cut waste, reduce carbon emissions and extend part life.

Using additive manufacturing, analysis and inspection techniques, the team successfully restored damaged pinion shafts from a wind turbine yaw gearbox, a key component that keeps turbines facing into the wind to maximise energy capture. Early trials showed that remanufactured parts could perform to original specifications following machining and NDT, saving up to 84 kg of CO2e per remanufactured component.
