The noise mitigation method, which Ørsted tested in collaboration with Jan De Nul using its installation vessel Les Alizés and contractor Aarsleff, involves a jetting technology attached to the monopile, which lowers the resistance of the surrounding sandy soil. This allows the foundation to sink into the seabed, completely removing the need for methods such as pile driving.

Beyond reducing the noise, the technology, once adopted at scale, can provide for more efficient and cost-effective installations of foundations, according to the offshore wind developer, who also said this was the first time a jetting technology was used to install full-size monopile foundations.
