Second offshore wind farm being installed in France

The second offshore wind farm currently being installed in France, the Saint-Brieuc marine renewable energy production site will supply Brittany with green energy. This new source of electricity production in the territory will contribute to the achievement of government objectives set by the Multi-year Energy Programs (PPE) as part of the national energy transition.

Emmanuel Rollin, Vice-President of Ailes Marines and Offshore Director France of Iberdrola: “Ten years after being named the winner for the Saint-Brieuc offshore wind farm, the installation of the first foundation marks a significant step in the realization of this ambitious project for the production of renewable marine energy. At a time when the electricity markets are experiencing very strong tensions, the Saint-Brieuc offshore wind farm – which will produce the equivalent of 9% of Brittany's electricity consumption – will contribute to its energy autonomy and to the essential energy transition. »

First offshore wind farm in France equipped with jackets

Saint-Brieuc is the first offshore wind farm in France equipped with jacket foundations. In 2014, following a consultation process initiated with sea users and in particular with professional fishing, Ailes Marines confirmed the use of this type of foundation.

Their lattice structures have a limited impact on the environment. They facilitate the circulation of water masses and biodiversity while promoting the artificial reef effect.

These foundations with triangular bases, weighing 1,150 tonnes, with a height of 75 meters and 25 meters on each side, are a metal trellis fixed to the seabed by three piles of 18 to 47 meters long, previously installed by the Aeolus.

For their transport and installation, a fleet of five vessels is mobilized and managed from the Ailes Marines maritime coordination center located in Pleudaniel (Côtes d'Armor):

    • Two vessels for installation, the Seven Borealis for lifting and installing the foundations, the North Sea Giant for sealing;
    • Three tug vessels (Kamarina, Eraclea, Onyx) and two barges (Sarens Caroline, H401) for transport.

Continuation of environmental security measures

During this phase of work, Ailes Marines continues security and environmental monitoring measures.

Furthermore, the partnership established with CEDRE made it possible to consolidate the anti-pollution system during the construction phase of the park, with the implementation of new protocols, response means and equipment.

This system was successfully tested during full-scale sea exercises in the presence of CEPPOL (Practical Anti-Pollution Expertise Center) and CEDRE at the start of 2022.

Two surveillance and information vessels are constantly operating on the site during this phase of the work.

In addition, environmental monitoring measures for the work (turbidity, fisheries, marine mammals, birds, acoustics, etc.) continue during all phases of installation of the constituent elements of the park.

Information on works for sea users

In order to inform residents and in particular users of the sea, Ailes Marines has opened an online information space dedicated to maritime work. It presents the nature and organization of the work, as well as information concerning navigation, in addition to the orders of the Maritime Prefecture.

All information concerning the Saint-Brieuc offshore wind farm project developed by the company Ailes Marines is available on the website www.ailes-marines.bzh
