Description:
The aim of the project was to develop a new foundation concept for offshore wind turbines by the collaborative partners of Vallourec Deutschland GmbH (Vallourec), the Fraunhofer Institute for Wind Energy and Energy System Technology North-West (IWES) and the Institute for Geotechnical Engineering Hanover (IGtH). With this new foundation variant, the load-bearing structure of wind turbines is to be founded using several comparatively small piles.
The connection of these piles to the load-bearing structure is to be ensured with the help of an adapter provided for this purpose. Furthermore, due to the use of comparatively small diameters, the foundation piles are not to be installed using conventional impact driving, but instead using a relatively new installation method, namely by simultaneously turning and pressing the piles. Piles with a diameter of several metres generate hydro-sound during driving, which exceeds the permissible limit values without further precautions. The use of such a new method will have less impact on marine fauna and ensure compliance with environmental constraints.
