Iberdrola is to start the second construction campaign on the 496MW Saint-Brieuc offshore wind farm, off the coast of Brittany this month.
During January, the project will continue with the installation of the cabling between wind turbines, depending on weather conditions.
In mid-January 2023, work is scheduled to begin on laying the wind farm’s interconnection cable.
In total, 90 kilometres of 66 kV high-voltage alternating current interconnection cables will be commissioned.
Drilling and pile installation work will resume in the first quarter, when anchoring of the remaining 66 piles will begin.
Thus, in the second half of the year, work on the offshore wind platforms will resume and the assembly of the wind turbines will begin.
The company has completed the first campaign of the works with the installation of 65% of the piles and 40% of the offshore wind platforms of the plant.
These elements have been manufactured at Windar’s facilities in Avilés and Navantia’s in Fene, respectively.
In total, 124 piles have already been installed, which will anchor the substation and 40 of the 62 wind turbines of the wind farm to the seabed.
These cylindrical pieces of steel, each 2.6 metres in diameter and weighing 150 tonnes, are between 18 and 47 metres long.
On them are fitted, with milimetre precision, each of the three-legged platforms that will support the turbines.
