Research and development is being carried out into all aspects of the industry as it attempts to emerge as the main source of renewable energy throughout Europe. An integral component of a wind turbine, the drivetrain is continually evolving as new concepts and designs are explored. As larger turbines are developed, and more wind farms are installed in deeper water, the service and maintenance of each component must also be considered. The design of drivetrains is moving towards direct drive technology, and new initiatives are also being developed in hydraulic and hydrodynamic technology. All of the new concepts and designs have reliability as a central aim in development, as drivetrain failure is a big contributor to the time a wind turbine spends out of commission. Operation and Development Planned maintenance at sea is a much more complicated routine than on land, and unexpected service visits are highly unwelcome. A wind turbine drivetrain may have a yearly maintenance routine consisting of generator brush inspections, gearbox oil and filter changes, LSS bearing grease refill and container removal. The extra overheads of a boat, a crew, and sea trained technicians can easily amount to several thousand pounds; and the weather can delay schedule and increase the costs. According to data gathered from existing offshore wind farms, drivetrain, generator, and gearbox failures account for around 14% of all down time for offshore turbines. Due to the complexity of repairs, however, they account for 39% of the time a turbine is out of commission per year. Typical failures include HSS generator and bearing damage, coupling degradation and internal gearbox component failures.

Wind Drivetrain: Reliability and Serviceability of Drivetrains
An integral component of a wind turbine, the drivetrain is continually evolving as new concepts and designs are explored. As larger turbines are developed, and more wind farms are installed in deeper water, the service and maintenance of each component must also be considered.
