WIND Turbine GEARBOX Service


A gearbox is typically the ideal solution for increasing rotational speed in wind turbines from a low-speed rotor to the higher speed required for an electrical generator. However, because of the varying loads and environmental conditions that come with wind-powered energy generation, it is important to ensure that gearbox components remain in good condition. Wind Turbine drive-trains can sustain severe transient loading during regular operation, not to mention startups, shutdowns, and emergency stops that over time will take a significant toll on the drive-train. If and when you require expert support to address the drive-train issues of your fleet, FGGS is here to provide industry­-leading inspection and repair services to ensure your turbines perform reliably.
