Saipem has completed installation of the offshore substation for Iberdrola-owned company Ailes Marines at the 496MW Saint-Brieuc offshore wind farm off the coast of France.
The Saipem 7000 vessel carried out the work in two stages.
First, the 1630-tonne jacket foundation was installed on its four piles, followed by the 3400-tonne topside on 6 July, Ailes Marines said.
Smulders carried out the engineering and manufacturing of the jacket foundation and the metal structure of the topside.
Equans designed and equipped the low voltage electrical part of the topside, including the auxiliary systems and the integration of the medium and high voltage equipment supplied by GE Grid Solutions.
The jacket and topside were pre-assembled by Smulders at the Hoboken yard near Antwerp in Belgium.
Final assembly of the topside was carried out at Equans’ shipyard in Hoboken.
The final assembly of the jacket foundation was carried out at the Heerema shipyard in Vlissingen in the Netherlands.
Iberdrola France offshore director Emmanuel Rollin said: “In a few months, at the end of 2023, the Côtes d’Armor department, with the Saint-Brieuc offshore wind farm, will be the leading contributor of renewable energy in Brittany by producing the equivalent of 9% of the Region’s total electricity consumption.”
