DEME has completed the installation of all 62 jacket foundations at the Dieppe-Le Tréport offshore wind farm.

All 62 jacket foundations were in place less than a year after the first foundation was installed in September 2025. The campaign was carried out by DEME’s jack-up offshore installation vessel Innovation.

The installation work involved 32 rotations between the port of Cherbourg and the offshore site. The jackets were placed on 248 pin piles previously installed by DEME’s jack-up offshore installation vessel Apollo.

DEME said the work required cooperation among project partners and stakeholders, with teams working both onshore and offshore.

DEME will deploy its jack-up vessel Norse Energi to transport and install 69 turbines in the Dutch North Sea, following an earlier foundation installation award. Preparations are scheduled to begin in 2028.
The EIB loan will support up to 25 second-generation survey vessels, remote sensing and underwater robotics, while a separate agreement extends €500 million in existing debt facilities to December 2031.
CBED has taken delivery of the vessel, which will be renamed Wind Dedication and chartered back to Seaway7 for existing projects until early 2028, with a full repaint planned at its next drydock.
