Wind farm work for Brest
The Port of Brest in northwest France is expanding its facilities to cope with wind farm operations at the Saint-Brieuc offshore wind project writes Dag Pike.
A planned marine renewable energy hub that is being built at Brest has now been reached the stage in its construction where work on the reclamation of an extensive area development can commence. The planned area being reclaimed at the port comprises a wharf and a long curved dyke and the two have now been connected so that dredged material can start to be pumped into the area between the two. The area is to the south of the Zone Industrielle Portuaire de Saint Marc.
The wharf which will form the loading and discharge part of the wind farm operations area is 400 metres long and this has finally been connected up to the 900 metre long curved dyke that forms the seaward protection side of the area being reclaimed. The reclaimed area between the dike and the wharf will be filled out by dredged sediments in two stages, from October 2019 to April 2020, and then during the winter of 2020/2021. The area will be available for use in 2024 after the drying and soil strengthening works have taken place with the sediments. The 1.25 million cubic metres of sediment required will come from the dredging operations in the port.
The 400-metre wharf has been designed to handle heavy loads and will be available for use in the Spring 2020. When the whole project has been completed the total area available for wind farm operations will extend to 400,000 square metres. The wharf will be used by Ailes Marines, the company which is the developer of the 496MW Bay of Saint-Brieuc offshore wind farm in the Bay of Biscay.
The Port of Brest, which is investing €200 million in this development, has said that the wharf will be use for partial construction of the wind farm’s 62 jacket foundations. It is anticipated that the facility will also be used for work on the tidal marine energy projects that are taking place in the waters around the island of Ushant close by the entrance to the port.
