Adwen and Fraunhofer IWES have signed an agreement to test the drivetrain for Adwen’s next generation 8MW offshore wind turbine. Under the terms of the agreement, the 8MW drivetrain will be tested at IWES’s dynamic nacelle testing laboratory or ‘DyNaLab’ in Bremerhaven, Germany, which is to be inaugurated on 20 October. Fraunhofer IWES has invested around €35 million to design and build the facility.
The testing process will get under way in December 2015 and will cover mechanical testing of drivetrain components. “By simulating operational conditions a critical move forward will be achieved in the verification of the gearbox, bearings, couplings, shaft, generator and converter,” said Adwen. “The process will allow individual and fully integrated subsystems to be validated as well as the complete drivetrain at full power, which is paramount for derisking before prototype erection in 2016.”
Adwen’s 8MW turbine has been selected for a pipeline of projects amounting to almost 1.5GW. Series production is due to start in 2018 at Adwen’s facilities in France and Germany.
