Strengthening environmental monitoring
during drilling works
Lézardrieux / Saint-Brieuc / Paris - April 28, 2021 -
Durant la première phase des travaux de forage qui se déroule de mai à octobre 2021 sur la zone nord du périmètre du parc de Saint-Brieuc, Ailes Marines instaure des mesures renforcées de suivis en temps réel sur le bruit et la turbidité (état trouble de l’eau).

Des mesures de contrôle renforcées de la turbidité
During the drilling of the anchor piles for the wind turbine foundations, Ailes Marines is introducing real-time monitoring of turbidity on 9 foundations in order to prevent the authorised thresholds from being exceeded.
These measurements concern 3 foundations positioned on 3 different types of marine subsoil representative of the bay (outcropping rock, pebbles and boulders, sand and gravel).
These monitoring measurements are carried out by a monitoring network of 5 control stations (buoys) which detect any variations in turbidity.
Three alert levels set up by prefectural decree will be monitored by Ailes Marines, in order to limit the effects of the drilling and pile installation work on the environment. Increased monitoring, a reduction in drilling speed or a temporary halt to the work will be applied depending on the threshold exceeded.
Des mesures de suivis renforcées de bruit
In order to contribute to the improvement of knowledge on noise in the marine environment, Ailes Marines is continuing the studies carried out since 2018, with reinforced monitoring of acoustics during the construction phase, in order to confirm the impacts identified prior to the construction phase in the context of the impact study and the first tests in September 2020.
Continuous measurements will be carried out on the representative positions of 9 foundations.
They are part of the continuity of the scientific studies conducted by Dr. Laurent Chauvaud, research director at the CNRS, Prof. Frédéric Olivier of the Muséum national d'Histoire naturelle and Dr. Delphine Mathias and by Michel André, Professor at the Polytechnic University of Catalonia (UPC) and Director of the Bioacoustic Applications Laboratory (LAB).
De nouvelles mesures complémentaires
The choice to intensify these measures is the result of consultations held over the last few weeks between all the users of the sea, the Côtes d'Armor prefecture and the maritime prefecture.
These measures are in addition to the forty or so environmental measures included in the prefectoral authorisations for the project and carried out by Ailes Marines.

Les impacts sonores du forage sont compatibles avec le cycle de vie normal des espèces halieutiques étudiées. Ailes Marines a décidé d’abandonner la technique de battage et de privilégier la méthode du forage pour l’installation des pieux. Les turbidités générées pendant les travaux auront une incidence faible sur le milieu. L’Ifremer valide l’état de référence des études de la ressource halieutique réalisé par Ailes Marines et RTE.
