TurbineKey Project GDF Suez

GDF Suez and Siemens Energy needed to replace their existing gearbox with a higher rated Flender-Graffenstaden gearbox to accommodate the turbine upgraded capacity. The new gearbox had a different shaft elevation and thermal signature so the original gearbox alignment position and target were no longer relevant.

GDF Suez and Siemens energy needed a way to swap out the gearbox in a compressed outage duration and receive an OEM warranty on the new gearbox and alignment. As a result, Siemens decided that the TurbineKey service provided by ACQUIP and FGGS was the best solution for this case.
