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 the jack-up vessel Innovation.

The installation took place on a rocky seabed and in tough offshore conditions. DEME deployed a 350-ton offshore foundation drill, co-developed with Herrenknecht, along with the 60-meter-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.

Following the 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.
