Installation of all 62 jacket foundations has been completed at the
Dieppe - Le Tréport offshore wind farm, marking a major construction milestone in under a year after the first foundation was installed in September 2025.

The installation campaign was carried out by the jack-up vessel Innovation, which completed 32 voyages between the port of Cherbourg and the offshore site. The jackets were installed on 248 pin piles previously placed by the jack-up vessel Apollo.


The milestone highlights the large scale of logistics and coordination required to deliver an offshore wind project in France.

Project partners said the achievement was made possible through close collaboration between contractors and stakeholders,with careful planning and coordination between onshore and offshore teams throughout the installation process.

The completion of the foundation installation clears the way for the next phase of offshore construction as work continues towards commissioning the wind farm.
