The AdBm NMS reduces underwater noise through the use of specially-designed and rugged injection-molded Helmholtz resonators, which provide reliable and predictable noise reduction at a low cost. The application of these resonators can be customized to meet the needs of any particular offshore project.
The AdBm NMS was tested in a deployment system engineered by Van Oord. The system, with its integrated the AdBm noise-mitigation technology, was successfully tested on five piles. When used in combination with only a single big bubble curtain, has been proven to meet Belgian and Dutch regulations.
“We are very pleased both with the performance of our noise-mitigation system, and with Van Oord’s decision to use our technology on their upcoming Borssele project,” said Dr. Mark S. Wochner, President & CEO. “This technology is now ready for the market, and another exciting outcome of this demonstration is that we have also gained numerous insights into how to further increase the system’s performance.”
Demonstration analysis was performed by itap GmbH and TNO, and funding was provided by a Renewable Energy Grant from RVO, and supported by TKI Wind op Zee. As a result of this successful demonstration, the AdBm NMS will be used commercially by Van Oord at the Borssele Offshore Wind Farm Plots 3, 4, and 5.
Liz Burdock, CEO & President of the Business Network for Offshore Wind congratulated AdBm Technologies , a member of the Network, for its successful demonstration of NMS.
“Noise mitigation is especially important on the U.S. East Coast because the loud noises caused by pile driving offshore wind-turbine foundations can disrupt marine mammals in this area, especially whales,” said Burdock. “As an added bonus, the NMS is a passive system that doesn’t require the use of an air compressor onsite, which means less burning of diesel fuel and no stirring up of sea floor sediment.”
