The increasing length of recent large rotor blades with their growing mass and static moments brings new challenges with regard to the design of their blade connections. Since 2008, WINDnovation has designed approximately 250 blades and blade connections with very different individual solutions.

Enercon is the first wind turbine manufacturer to break entirely new ground in handling rotor hubs on the assembly line – instead of using cranes and slings, Enercon relies on a compact turning table from RUD Ketten Rieger & Dietz, based in Aalen (Baden-Württemberg, Germany).

When discussing with potential partners about the visual inspection of wind turbines with drones, the first question that arises is which drone do you recommend? Inspecting wind turbines is not just about flying around the rotor blades and gathering high resolution pictures of everything. It is about image quality and supplementary metadata that improve the overall value of, and information about, an inspection flight, and processing and presenting the results in a manner that allows rotor blade experts to make precise decisions.

As the Biden administration prepares for unprecedented development in renewable generation, Asia-Pacific wind generation is hitting record level spend, and South Korea unveils seismic plans to build the world’s largest offshore wind farm, wind farm operators are positioning themselves to capitalise on this all-time high, gigawatt power generation fever.

Offshore wind farms are getting more attention as a source of renewable energy due to high and consistent offshore winds. These reliable offshore winds favour the construction of large offshore wind farms despite their high installation and operational costs. However, the deployment of such large offshore wind farms in proximity to each other, as planned in the North Sea, can significantly affect power generation and increase economic losses of the downstream wind farms.

As wind turbines installed in the late 1990s and early 2000s begin to be decommissioned, it is important to consider sustainable options for handling their end-of-life materials. Recycling and other circular economy methods can reduce the material intensity of wind energy production, but composite blades are more difficult to recycle than many other major wind turbine components. Several circular economy strategies have been developed for processing composite materials, thereby enhancing the sustainability of electricity production from wind energy.
