The 61st and final XL-monopile is now in place, marking the successful completion of the drilled foundation installation campaign at the Îles d’Yeu and Noirmoutier offshore wind farm with our jack-up vessel Innovation.
The installation took place on a rocky seabed and in tough offshore conditions. We deployed our 350-tonne offshore foundation drill, co-developed with Herrenknecht, along with the 60-metre-high MODIGA, which stabilizes and protects the drilling and installation process from harsh ocean conditions. These innovative technologies enabled safe and efficient operations throughout the installation campaign.
This milestone is above all the result of the people behind it — the skill, dedication and teamwork of everyone involved. From our offshore crews and onshore teams to our client Les Éoliennes en Mer Services, and all partners and subcontractors, this achievement was only possible thanks to close collaboration and a shared commitment throughout the campaign.
Following our work at Saint-Nazaire, France’s first large-scale offshore wind farm, this marks the second project in the country where DEME has delivered drilled foundation solutions — bringing industry-first technology to complex marine environments.
