Dutch marine contractor Van Oord has accomplished the set up of 62 jacket foundations on the Saint-Brieuc offshore wind farm, situated within the Bay of Saint-Brieuc, 16.3 kilometres off the coast of Brittany. The set up was carried out utilizing their set up vessel Aeolus.
Saint-Brieuc is the primary wind farm in France with jacket foundations. As soon as operational, the 496MW wind farm will generate sufficient clear vitality for the equal of 835,000 inhabitants.
Ailes Marines, owned by Iberdola, contracted Van Oord for the transport and set up of 62 jacket foundations for the wind generators (3 pin piles every) and the 4 basis pin piles for the offshore substation. Van Oord deployed its offshore set up vessel Aeolus to put in the 190 pin piles and teamed up with different business companions to put in the jackets.
Circumstances for constructing a wind farm within the Bay of Saint-Brieuc have been difficult. The extraordinarily laborious and rocky seabed and Atlantic environmental circumstances challenged our tools and experience. The Aeolus was subsequently upgraded and an in depth unfold of project-specific set up tools was engineered, constructed and utilised on the set up vessel.
To make sure that the Aeolus may very well be safely jacked above sea stage, the ft of the jacking system had been modified with a flex-pin development. As a result of geotechnical circumstances on the web site, an progressive drilling methodology was used to put in the foundations. Undertaking-specific drills had been collectively engineered and constructed with our accomplice Bauer Spezial Tiefbau and a newly designed and state-of-the-art drilling template functioned as a positioning and casing drilling device to make sure the exact placement of the pin piles.
Ivar Daemen, Undertaking Director Van Oord: ‘After executing quite a lot of initiatives in France, Van Oord reached an enormous milestone by finishing our very first extremely complicated offshore wind venture right here. Because of the nice collaboration between our shopper Iberdrola, companions and devoted venture group, we now have now completed our work on the Saint-Brieuc venture. We’re proud to have contributed to France’s vitality transition.’ Supply: Van Oord
