Generator Services Extending lifetime, boosting profits Fleetwide all-round repair services Our R&D engineers are continuously developing innovative repairs and upgrades for both Vestas and non-Vestas genera tors – making us a genuine fleetwide service partner. In working with Vestas, you will benefit from a true one-stop-shop supplier that offers service packages including labor, proprietary craneless solutions and components in one place. Inspections The structural base of the generator is exposed to significant mechanical loads over its lifetime. A failure of the base can result in significant damages to your turbine, an issue mainly affecting older, welded generator supports. All failures begin with a crack. Our magnetic particle inspection technique allows us to detect cracks early and perform cost-effective repairs that ensure the turbine’s structural integrity. Uptower and onsite repairs Carrying out repairs uptower and onsite is the most cost-effi cient renovation method available, potentially saving you 80% of the price of a new generator. That is why we continuously aim to offer as many uptower solutions as possible, currently including: • Bearing shields exchange • Replacement of bearing PT 100 sensors • Bearing journal repair • Replacement of rotor/stator cables • Rebalancing By choosing Vestas you can benefit from the insights and expertise of a generator producer. BENEFITS OF UPTOWER AND ONSITE REPAIRS • Optimising cost savings • Minimised downtime • Short lead time • Service flexibility • Only pay for what is fixed Repair loops and workshop repairs To help you minimise downtime, Vestas offers a unique generator exchange programme using repair loops from our workshops. To secure a fast return to service, we carry a stock of replacement generators and can swiftly deliver a replacement generator to your site. If you prefer a 1:1 exchange, we bring your generator to our industry-leading workshop facilities or one of our accredited partners sites. We conduct in-depth analysis and troubleshoot the full scope of technical problems with access to a wide range of skilled personnel and technology. In the repair shops we are able to dismantle, clean and inspect every generator before writing a report on the required renovations and interventions. During the repair process, each generator undergoes a rigorous test. If the required repair work is not deemed feasible after taking the generator age and other features into account, we will recommend alternative solutions. Our generators are available as spare parts as well. 2
