Van Oord and AdBm Technologies have successfully demonstrated the new AdBm Noise Mitigation System (NMS), with support from TNO. Van Oord will be deploying the system at Borssele 3,4 & 5.
The NMS system reduces underwater noise resulting from offshore pile driving wind turbine foundations. It 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. The system was designed and built at Van Oord. It works as it were window blinds that can be put up and down easily.
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.
The development of this innovative system and the related trials were funded through a Renewable Energy Grant from RVO and supported by TKI Wind op Zee. Source: Van Oord
