Three phases of work between 2022 and the end of 2023

From March 2022 until 2023, the Van Oord company will continue the installation of anchor piles for “jacket” type foundations (3 piles per foundation).

In 2022, the Van Oord company will also install the first foundations, the production of components of which by the Navantia-Windar company continues on the Brest polder. Twenty-four foundations are already assembled and stored at the company's site in Fene, Spain, and twenty-one foundations are currently being assembled. The first foundations will arrive in the park area at the beginning of the second half of 2022.

During the spring, Saipem will transport and install the electrical substation on site.

At the same time, the Prysmian company will begin the installation and burying of 90 km of three-pole submarine inter-wind cables.

All of these phases of work will mobilize more than twenty vessels on site at peak activity.

Environmental control and monitoring measures

In 2022, during the work phase at sea, Ailes Marines will continue environmental monitoring measures in accordance with regulatory requirements including monitoring of noise, turbidity, birds and marine mammals, bats, fishery resources, the quality of water and sediments.

New monitoring will emerge on the birds of the bay. Indeed, Gannets and Alcidae will be equipped with tags to follow their movements in the Bay of Saint-Brieuc. This monitoring, undertaken gradually over recent years, is carried out by independent environmental scientific research offices.
