Ailes Marines has selected Van Oord for the transport and installation of the foundations of the Saint-Brieuc offshore wind farm.
Saint-Brieuc / Paris / Rotterdam - May 6, 2020 - Ailes Marines, in charge of the construction, installation and operation of the Saint-Brieuc Bay wind farm, has selected the Dutch company Van Oord to transport and install the 62 jacket foundations (metal lattice structures) as well as the piles for the foundations of the electrical substation.
Transport and installation work
Van Oord will begin offshore operations in 2021 with the installation of the anchoring piles, using its vessel Aeolus. The Aeolus will be assisted by a second ship in 2022, for the installation of the jacket foundations, which will be manufactured in Fene (Spain) and Brest (France).
Built specifically for the installation of offshore wind farms, the Aeolus was commissioned in 2014. Its main crane has a lifting capacity of more than 1,600 tonnes. The Aeolus is fully suitable for the transport and installation of foundations and wind turbines. Its advanced lifting system, with its giant legs, each measuring 85 metres and weighing 1,280 tonnes, allows the Aeolus to be raised and operate in water depths of up to 45 metres.
A partnership based on trust
Prysmian will provide a complete turnkey package including the design, supply, installation and all testing for the commissioning of the 90 km of 66 kV three-core subsea High Voltage AC (HVAC) high voltage three-core cable with XLPE insulation. The phases of the cables (cores and insulation) will be manufactured in the Prysmian Group's plants located in Montereau-Fault-Yonne and Gron (France), and the final assembly of the three-core cables will be carried out in Nordenham (Germany). Delivery and commissioning are scheduled for the end of 2022.
Saint-Brieuc offshore wind farm
The Saint-Brieuc offshore wind farm will be located in the Bay of Saint-Brieuc in Brittany, 16.3 kilometres off the French coast. When completed, the wind farm, with a total capacity of 496 MW, will produce 1,820 GWh per year, equivalent to the annual electricity consumption of 835,000 inhabitants. Installation work will take several months and will continue until 2022. The wind farm will be fully operational in 2023.
"Van Oord has been carrying out various projects in France for a long time. The most recent example is our participation in the various phases of deepening the Seine. The Saint-Brieuc project will be our first offshore wind farm project in France and I am proud that we are participating in it. Especially as we are delighted to have the opportunity to work with Iberdrola again. By carrying out this offshore wind farm project, we are also contributing to the European objective of reaching 32% renewable energy by 2030. »
"After making the investment decision, Ailes Marines is pleased to sign this contract with Van Oord to transport and install the 62 jacket foundations and piles for the electrical substation foundation of the Saint-Brieuc project. This project will play an important role in France's transition to a green economy. Given the difficult conditions linked to the pandemic crisis, we are also contributing to the recovery of industrial activity in France and the rest of Europe. »
