Fraunhofer IWES Wind Lidar Buoy achieves Stage-3 maturity level

The Fraunhofer IWES has presented a series of proofs of the quality and reliability of its FLS wind measurements. By achieving maturity level 3, the Fraunhofer IWES ZX wind lidar buoy joins the short list of stringently validated FLS types…

Active for a sustainable future: challenges in the production of green hydrogen from wind and solar energy

Authors: Telsche Nielsen, Viktor Deleski At Fraunhofer IWES, we are actively committed to renewable energies. Day in, day out, we support and further the development of technologies in the fields of wind energy and hydrogen. As an institute for applied…

Might stick around: IWES tackles rotor blade production challenges with the Variable Glue Applicator

The longer the rotor blade, the more glue is needed to bond the blade shells together. IWES scientists have developed the Variable Glue Applicator to simplify and improve the application of adhesive.

Offshore installations: Weather and project risk analysis at IWES

Here at IWES, we assess weather risks using the Advanced Weather Time Series Scheduling (AdWaTSS) method, which is more precise than just statistics, and frequencies of tasks. For the offshore wind industry, we analyze and verify the time schedules of…

The step to the digital test procedures: hybrid testing of wind turbines

The requirements for wind turbine test benches are continuously increasing and demand, in turn, investments in test bench expansions or new test benches. Fraunhofer IWES has developed a hybrid test procedure to expand the capacity of existing testing facilities and…

Nacelle Testing for Future Wind Turbines – What Lies Ahead?

Over the years, we have witnessed rapid growth in both onshore and offshore wind turbine systems. At the same time, the entire wind industry has become even more competitive, as wind turbine manufacturers aim to launch their product on the…

What Happened to You, Buddy? The Evaluation of Blade Bearings

Authors: Dr.-Ing. Matthias Stammler, Karsten Behnke Whenever we have the opportunity to look at damaged bearings, we as scientists love to do so. Be it the bearings we tested in our own lab or bearings directly from the field, it…

Waves, buoys, offshore wind energy: Wind measurement in the German Bight

Fraunhofer IWES Wind Lidar Buoys floated in the German Bight, east of the Bard Offshore 1 wind farm, at times last year. These yellow buoys ensure that comprehensive wind measurement data and meteorological parameters can be precisely recorded and evaluated….

Large-Scale Wind Farm Effects – A Key Contributor for Economic Wind Farm Operation?

Ever since the construction of the first wind farms began in the 1980s, the impact of wind turbines on the flow – the wake effect – has been a major focus not only in the field of wind energy research…

How do resonance-based testing methods increase the efficiency and lifespans of support structures?

Efficient use of materials and a long lifespan are important KPIs in the optimization of offshore wind turbines. For future, larger support structures, which are particularly expected in wind farms at greater water depths, the behavior of the foundations, in…
