Ailes Marines, a subsidiary of Iberdrola, inaugurates the temporary technical base of the Saint-Brieuc offshore wind farm in the port of Saint-Malo
Saint-Malo / Saint-Brieuc / Paris - February 24, 2023
- The temporary technical base of the Saint-Brieuc offshore wind farm was inaugurated on Friday, February 24, 2023 by Daniel Cueff, Vice President of the Brittany Region and Stéphane Alain Riou, Director of Offshore Wind Energy Iberdrola France in the port of Saint-Malo.
- The maintenance operations of the park will be carried out temporarily from this base with the vessel EDDA Goëlo.
- This vessel will be operational from the second half of 2023 for a maximum duration of 5 years.
- During this period, Ailes Marines hopes to finalize the installation of the maintenance base in the port of Saint-Quay-Portrieux.
A temporary technical base coupled with an offshore service vessel based in Saint-Malo
The temporary technical base of Ailes Marines, a subsidiary of Iberdrola, located on Avenue Louis Martin in the port of Saint-Malo, consists of a 210 m2 administrative area that can accommodate approximately 20 people and a 120 m2 technical area.
This base is intended for maintenance activities for the first years of operation of the offshore wind farm in the Bay of Saint-Brieuc, which will be carried out by the technical teams of Siemens Gamesa Renewable Energy.
These teams will work on the park site with the SOV (Service Operation Vessel - technical support vessel) EDDA Goëlo. The port of Saint-Malo is perfectly suited to the vessel's large size (82.40 meters long).
The EDDA Goëlo will carry Siemens Gamesa Renewable Energy technicians, Ailes Marines operating personnel, and people working on the substation, foundations, cables, etc., as well as the spare parts needed for maintenance operations. It can accommodate up to 40 technicians and 20 crew members. The vessel will work in the park in two-week shifts. Every 14 days on average, it will then return to port to resupply and change crew.
A temporary solution for maintenance activities
The EDDA Goëlo will start operating in the Saint-Brieuc park in 2023. It will operate under the French flag and part of its crew will be French. This vessel and the temporary technical base in the port of Saint-Malo will be operational for a maximum of 5 years.
The progressive commissioning of the wind farm requires the use of an offshore service vessel based in Saint-Malo in order to ensure maintenance activities as soon as the first lines of wind turbines are installed.
This solution remains temporary, however, while waiting for the final realization of the maintenance base in the port of Saint-Quay-Portrieux.
The maintenance base of the park in Saint-Quay-Portrieux, an opportunity for the territory
The future maintenance base located in the port of Saint-Quay-Portrieux represents a real economic opportunity for the Côtes-D'Armor territory with approximately 80 direct jobs mobilized for the maintenance activities of the 62 wind turbines for the entire duration of the operation of the wind farm, at least 25 years.
After 2 feasibility studies, technical and economic, the port of Saint-Quay-Portrieux presents all the necessary conditions for the maintenance vessels to carry out their operations. The port of Armor, in deep waters, has an external development area to accommodate storage and handling activities. Its geographical position is optimal, about 50 minutes away from the wind farm. It remains accessible 24 hours a day, 7 days a week.
