SeaState5 is developing an acoustic screen that absorbs the noise emissions generated during the installation of wind turbine foundations.
We have created acoustic panels that contain 100 absorbing elements per panel. The panels can be integrated in a foldable noise mitigation system.
The benefits of our system:
The core of our technology consists of metamaterial. This is a material that is engineered to have properties that are not found in nature. On microscopic level, it is a structure with a specific shape and size, made from normal plastics or metals. On macroscopic level, it behaves like a single material. Macroscopic properties like absorption can be engineered by adjusting the microscopic structure.
With this technology, SeaState5 has created acoustically absorbing elements. Because the size of the absorbing elements is much smaller than the wavelengths contained in the noise, multiple elements work as one single barrier.
Full-scale operational - 2021
2020 - Pilot test
Field simulations - Aug 2019
In-house simulations show that the noise generated during the installation of offshore wind foundations is mainly water-borne and can be absorbed with one high-performance acoustic noise screen
Jun 2019 - Lab-scale test small panel
A panel of 3x3 absorbing elements shows the predicted noise absorption and confirms that the technology can be scaled
Concept validation - Nov 2018
Lab tests confirm the acoustic performance of a single absorbing element
Jul 2017 - Commercial feasibility
A feasibility study shows that current noise mitigation techniques are ineffective and that SeaState5's technology has the potential to reduce costs with 67%
Technology research - Jan 2017
Start of technology research on the mitigation of underwater noise
We have validated our technology on lab scale and now we are looking for partners to test our acoustic panel in a pilot project.Contact us
