Developed by Moventas’ US-based engineers and following a year of successful up-tower full-helical gear repairs in North America, the company can now perform onsite inspections and repairs of high speed, low speed and intermediate assemblies to its own gearboxes as well as competitor models.
“Our goal is to significantly shorten response time, reduce customer cost and to continue to lead the industry in repairs that can be done on-site rather than in a workshop," said Olli Välimäki, Senior Vice President of Service with Moventas.
"This is a significant cost-saver for the industry, making it even more competitive compared to traditional energy forms than before,” he said.
By utilizing a mobile service unit and a small hydraulic crane, the Moventas up-tower repair eliminates the costs associated with mobilizing large boom and secondary cranes normally required to bring the complete gearbox down from the nacelle. Shipping costs to and from the workshop are also eliminated, as well as the cost of the longer downtime of the turbine.
Moventas is building multiple self-contained mobile workshops specifically designed to perform this service at the wind site. Five mobile workshops will be strategically located in North America and an additional two units will be located in Germany and Spain before the end of the year.
