Adwen and Fraunhofer IWES sign agreement for the testing of 8 MW wind turbine

Adwen, a joint venture between AREVA and Gamesa for the offshore wind industry, and Fraunhofer IWES have signed an agreement to test the drivetrain for Adwen’s next generation wind turbine of 8 MW rated power. Under the terms of the agreement, the 8 MW drive train will be tested in IWES´s new Dynalab (Dynamic Nacelle Testing Laboratory) site, a unique test stand located in Bremerhaven, Germany, which is to be inaugurated on October 20th.

The DyNaLab is one of the world’s largest and the most versatile test facility for nacelle testing. Fraunhofer IWES has invested around €35 million over the past years to design and build the facility.

The process, to be carried out from December 2015, will cover mechanical testing on the integral chain of drive train components. By simulating operational conditions but as well offshore conditions for extreme and fatigue loads, a critical move forward will be achieved in the verification of gearbox, bearings, couplings, shaft, generator and converter. The process will allow individual and fully integrated subsystems’ validation as well as complete drive train operation at full power, paramount for de-risking before prototype erection in 2016.

Adwen’s 8 MW wind turbine has already been selected for a pipeline of projects reaching almost 1.5GW. Its serial production is scheduled to start in 2018, at Adwen’s industrial sites in France and Germany.

Maite Basurto, Chief Technology Officer of Adwen said: “The IWES Dynalab test stand is an invaluable asset for the wind industry. Adwen immediately chose to take advantage of this opportunity: IWES Dynalab testing is a complementary step in our extensive validation program. It will contribute to having a faster certification process and finally a more reliable wind turbine available in serial production in 2018”.

We expect to offer the wind industry valuable support for a more reliable design process and faster secure market introduction of new wind turbines” pointed out Prof. Jan Wenske, deputy director of Fraunhofer IWES.
