Moventas, a wind and industrial gear manufacturer and service provider, has recently completed another full wind turbine drivetrain service project in extreme conditions.
Moventas started the on-site part of a full drivetrain repair project of four 3MW turbines in Sweden in June. The serviced turbines are located in Vindpark Vänern Kraft AB’s offshore wind park on Europe’s third-largest lake, Vänern.
The 13-week long project consisted of the refurbishment of four 3MW drivetrains, two of which were replaced with a Moventas gearbox. Four full factory services with refurbishment of components were executed in Moventas’ service facilities in Finland. All of the turbines were also equipped with the Moventas Condition Management System, CMaS, completed with a remote diagnostics service.
Planned by ÅF Industry in Karlstad, the project was executed on the weather’s terms, as the turbines were accessible only during favorable wind conditions. The schedule was thus tight as offshore logistics included moving specific tools, cranes and other lifting equipment, as well as the repaired and replacement gears on a fleet of boats.
Fast and effective factory repair was also a key factor in the project. This was the first time that the entire service process for this gear type was turned around so quickly. The customer, making refurbishment possible before lifting, bought two gearboxes. Furthermore, lifting could then be executed with exchange lift instead of a remove/repair lift. New geared parts were ready and waiting to be changed, when the old gearboxes arrived. Factory service was executed in only 12 days, according to a detailed process plan.
During the workshop repair, representatives of Vindpark Vänern Kraft AB visited the service facilities in Finland to see the condition of their old geared parts and to witness how the service is done in the factory.
Last tests and check-ups were completed on Vänern’s turbines two weeks ago. Everything was in order and the turbines are again running smoothly, with Moventas CMaS keeping an eye on all of them and preventing future damages.
The success in these challenging repairs proves that Moventas is able to carry out the most difficult drivetrain repairs in the wind industry fast and effectively.
