Adwen has begun testing the drive train of the AD 8-180 at the IWES Dynamic Nacelle Testing Laboratory (DYNALAB) in Bremerhaven. The validation process will continue until the end of the year and includes mechanical and electrical tests of the drive train and the primary tower components as a unit.

Scientists perform extreme load and fatigue load tests at the laboratory, which opened in October 2015. The laboratory simulates real-world operating conditions for the validation process. The testing procedure permits the validation of parts of systems both standalone and fully integrated. The complete drive train can be validated under full load. The manufacturer's aim with the simulations is to reduce the duration of field-testing to accelerate the certification process.

The preparation work on the test rig started towards the end of last year. The drive train was transported to DyNaLab in April 2016, where mechanical assembly followed, along with the installation of additional fittings for sensors and the lubrication system. More than 350 sensors on the drive train gather important data during the tests. In a further step, the entire nacelle of the AD 8-180 will be brought to the IWES DyNaLab to undergo final testing. Installation of a prototype with this nacelle is scheduled for the end of the year in Bremerhaven.

"It is an extremely important step forward in our comprehensive validation programme. It gives us the opportunity to test the essential core components of our wind turbine in the world's leading testing facility. It will also help us to get this turbine certified more quickly and ensure that it has an optimum performance“, said Maite Basurto, Adwen Chief Technology Officer (CTO).

ZF Friedrichshafen and Schaeffler are collaborating to develop new solutions for predicting the operating life of wind turbine gearbox components based on the actual loads that occur during operation. Since September, the first wind turbine gearboxes equipped with sensors and condition monitoring systems have been supplying operating data to a cloud-to-cloud solution to enable this to happen.

Sparrows Group has seen its position in the renewables market strengthened one year on from the acquisition of Alpha Offshore Service. The company confirmed that Danish-based Alpha’s revenue has increased by 46% in the past 12 months.

Slowly but surely the floating offshore wind energy sector is becoming more and more important, particularly because of the fact that the number of locations with shallow waters suitable for fixed-bottom foundations is limited. Floating wind is turning into a highly scalable future energy source because the wind resource in deep waters is extensive and offers a significant potential for marine renewable energy development and growth to many countries.
