Reducing Wind Turbine Vibrations for the Einstein Telescope in the EMR Region — •Tom Niggemann and Achim Stahl — III. Physikalisches Institut B RWTH Aachen University

The planned realization of the Einstein Telescope in the EMR region (Euregio Meuse-Rhine) requires a significant reduction of environmental disturbances, particularly those caused by seismic waves and the resulting Newtonian Noise. A significant contribution to these disturbances originates from the vibration modes of wind turbines, whose foundation and tower motions propagate through the ground and may compromise the sensitivity of the gravitational-wave detector. To mitigate these effects, several engineering measures are being investigated: the enlargement of foundations to lower eigenfrequencies and improve ground coupling, as well as the implementation of tuned mass dampers to suppress critical vibration modes. Complementary numerical simulations and studies are conducted to validate the effectiveness of these approaches. The overarching goal is to develop a robust vibration-reduction concept that reconciles the integration of renewable energy with the extreme requirements of gravitational-wave research.
