Iberdrola, through its subsidiary Ailes Marine, has confirmed that construction of the Saint-Brieuc offshore windfarm will begin on 3 May 2021
In 2021, construction work is planned from May to October in five zones located in the northern part of the windfarm.
Work will take place in this limited period to avoid interfering with the 2020-2021 scallop fishing season, which finishes at the end of April. Construction is expected to take three years overall.
Construction of the 496-MW windfarm will begin with the installation of the pin piles for the three-legged jacket foundations. To minimise the environmental impact of the piles, they will be bored into the seabed rather than driven in by pile-driving. Drilling will be carried out by Van Oord using the vessel Aeolus.
To allow fishing activity to continue at the site, Iberdrola has also undertaken to fully bury all of the inter-array cables. The trenches for the cables will be excavated between June and September 2021.
Work on the windfarm will be co-ordinated from Kerantour’s construction base in Pleudaniel, Brittany and from the port of Lézardrieux.
The project in the Baie de Saint-Brieuc will have an area of 75 km² and will use 62 8-MW Siemens Gamesa SG 8.0-167 DD wind turbines.
