Setec In Vivo, historical collaborator of Ailes Marines on environmental studies

With the aim of building a project that is both responsible and sustainable, Ailes Marine has surrounded itself with environmental specialists, in particular the marine environment and coastal oceanography consultancy, Setec In vivo. This collaboration, which began nearly ten years ago, is a long-term project.

Setec In Vivo

Specialists in data acquisition, exploitation and valorisation, Setec In Vivo assists numerous project leaders in the study of the marine and coastal environment, particularly in the field of marine renewable energy. Their areas of expertise include the laying of cables and underwater pipelines, port and maritime and river infrastructure development, dredging operations and the destination of marine debris...

Based in Brittany, Setec in Vivo has been providing numerous services throughout the region's coastlines for the past 20 years. This expertise gives them a thorough knowledge of marine and coastal ecology from the Atlantic to the English Channel.

Impact assessment & data

In order to fully meet the objectives of the impact study, numerous field campaigns were implemented over a period from September 2012 to March 2015.

With the overriding desire to respect the environment, the wind turbine siting area selected by Ailes Marines was chosen with a view to reconciling technical, environmental and landscape issues and uses.
In fact, several important criteria were taken into account when defining the siting area, namely

  • Professional fishing activities: The areas favoured by professional fishing (main scallop fishing grounds, for example) are avoided.
  • Natural features: The site is located outside of any Natura 2000 area.
  • The landscape: the siting area has been moved away from the Erquy and Fréhel capes, which are particularly popular tourist areas, especially in summer.
  • Bathymetry: avoidance of the deepest areas to the north and east of the tender area.

To assess the quality of the environment, put it into perspective with the effects of the project and thus evaluate the resulting impacts, Setec In Vivo and their contractors carried out the impact study for the Saint-Brieuc project.

Ailes Marines has chosen to develop a wind farm project that is environmentally friendly and integrated into the Bay of Saint-Brieuc. Ailes Marines has surrounded itself with specialists such as Setec in Vivo, enabling it, in particular, to put in place around thirty environmental measures whose objective is to avoid environmental damage, to reduce that which could not be sufficiently avoided and, if possible, to compensate for the significant effects which could not be avoided or sufficiently reduced (ERC sequence: Avoid, Reduce, Compensate).

Thus, throughout the project, Ailes Marines limits the impact of the construction and operation of the wind farm on the environment.

Ailes Marines is currently carrying out the baseline study (update of the initial state of the impact study) to re-qualify the environment before the works. These studies are being carried out by a number of service providers/partners, including Setec In Vivo, which has been awarded a contract to monitor the fisheries resource and benthic communities.
