Advantages of new blasting technology for wind turbines

End In 2023, Hagedorn Service GmbH completed a major dismantling project: Baben-Bertkow wind farm in Saxony-Anhalt, the team built 17 wind turbines and used a new blasting technique for the first time. The technology was developed by Hagedorn Service together with Deutsche Sprengunion, both companies of the Hagedorn Group.

For using this method, the team led by Hagedorn structural engineer Sven Lammert placed the Explosive charges at a height of 18 meters. As a result, there was a other methods required a much smaller drop bed and the tower could be mounted on the crane footprint that has already been prepared. In addition to the minimal space requirement and the reduced impact on surrounding areas and access roads. the technology used resulted in cost savings of around 30,000 euros. In Baben-Bertkow was able to successfully convert three E-70 turbines using the new method. and the rest of the stump was then mechanically dismantled.

"The advantages of our unique and the demolition method protected by the utility model are considerable. Because we are responsible for the blasting, especially the crane footprint, we protect the surrounding areas and due to the space saving, parallel to the dismantling with the Construction of the new wind turbine will begin. In this way, we save time and The energy transition is being driven forward more quickly," emphasizes Frank Kreimer, Managing Director of Hagedorn Service GmbH. Especially in the case of hybrid towers, the advantages of the new method.
