Van Oord and AdBm Technologies have demonstrated the new AdBm Noise Mitigation System (NMS).
The NMS reduces underwater noise resulting from offshore pile driving wind turbine foundations. This means less disturbance for marine mammals near the construction site.
The test results are favourable. For this reason, Van Oord will be able to use the NMS in future wind farms, amongst others during the construction of the Borssele wind farm.
The NMS uses special acoustic resonators designed and produced by AdBm Technologies which reduce the noise from pile driving. As a result of this technology, specific frequencies can be targeted which produce the most noise. This makes the NMS stand out from existing systems.
The NMS has been tested extensively. The result showed that the NMS, in combination with a Big Bubble Curtain (BBC), meets the Dutch and Belgian standards for noise emissions at sea, company added.
