Ailes Marines Inaugurates Saint-Brieuc Technical Base in Port of Lézardrieux

Ailes Marines’ technical base at the port of Lézardrieux in France, which serves the Saint-Brieuc offshore wind project, was officially opened on 25 February 2022.

The base was inaugurated by Stéphane-Alain Riou, the project’s Development and Territory Director, in the presence of local and regional officials.

Last year, the technical base in the port of Lézardrieux had in place an administrative area and a technical area with a diesel tank and a crane. As work on a heavy pontoon has been completed, allowing access to the port for boats transferring personnel working on the construction of the Saint-Brieuc offshore wind farm, the base has been put into full operation.

Ailes Marines, a wholly owned subsidiary of Spain’s Iberdrola, has also set up the Kérantour Maritime Coordination Centre in Pleudaniel, which consists of an administrative area, a maritime surveillance area, internal training facilities, and an equipment storage area.

The construction work on the Saint-Brieuc offshore wind farm began in May 2021 with pile installation for the project’s jacket foundations.

The pre-trenching campaign along the inter-array cable routes in the northern part of the wind farm was completed on 14 August 2021, five weeks ahead of schedule. The vessel Aethra also performed preparatory operations for the 2022 work sequence which will be carried out in the northern part as well.

The first phase of construction at the Saint-Brieuc offshore wind farm site was completed on 31 October 2021, when Ailes Marines said the work was scheduled to resume on 1 March 2022, at the latest.

The work in the first phase was concentrated in the northern zone of the wind farm to allow for the fishing activities in the southern part.

For the 2022 campaign, Ailes Marines plans to complete the installation of cables, the pin-piles, the 62 three-legged jacket foundations, and the offshore substation.

Offshore construction work is scheduled to be completed in 2023 and the wind farm is expected to be operational by the end of that year.

Once up and running, the 496 MW offshore wind farm, which will comprise 62 Siemens Gamesa 8 MW turbines, is expected to produce 1,820 GWh of electricity per year.
