Gearbox Services Flexible, fleetwide solutions for your business Reduce cost with preventive inspections and maintenance One of our primary strengths is our capability to perform preventive inspection and maintenance that prevents total component failure and workshop repairs. We properly inspect and classify gearbox damages on-site and document them in a customised report to save you both time and money on even- tual repair work. Choose your preferred repair level Your business has individual requirements. Deciding whether a faulty gearbox requires a full upgrade or only needs to be returned to functional state is dependent on your business case. Based on your asset management strategy, type of components and age of your wind farm, we can evaluate the best possible scenario for you. We have the capability, you have the choice. Basic Returns an item to a functional state after failure; only failed parts are replaced and covered by warranty. Complete Full disassembly and component assessment. Parts that are likely to fail will be replaced; critical design upgrades are included. Advanced Full disassembly and assessment, installing new bearings, applying all available upgrades. Save cost & time with uptower and onsite repairs We offer the following uptower and onsite repairs: • High-speed shaft and bearing (rotor and generator side) • Intermediate shaft and bearing (rotor and generator side) • Low-speed shaft Case study "A leading renewables energy company contracted us to perform preventive inspection on its fleet. During bore- scope inspection of the gearbox of a competing turbine brand a broken tooth was detected on the Low Speed Shaft. This type of fault normally requires replacement of the complete gearbox. Our engineering team conducted compatibility studies and successfully applied a Low Speed Shaft replacement instead, significantly reducing turbine downtime and overall repair costs. According to our knowledge to date Vestas is the only company capable of performing such an uptower operation on this gearbox type and platform.” Borja Fernandez Garcia TPO Manager, Vestas
