The 2.9 GW Hornsea 3 project has installed both offshore HVDC converter stations and advanced its export cable works, while investors prepare to compete for ownership and operation of its transmission infrastructure.

Seaway Phoenix is due at Hornsea 3 on 19 October 2026, while Grand Canyon 3 is scheduled to begin pre-trench survey and trenching work the following day, according to Ørsted’s construction notice.

OEG will deploy synchronised generators aboard a jack-up vessel for converter station commissioning and separate 150 kVA units with 3,000-litre fuel tanks for turbine installation and commissioning.

Heerema Marine Contractors’ Sleipnir has installed the second Hornsea 3 offshore converter station, completing installation of the project’s two offshore HVDC platforms.

The UK MAIB has launched a full investigation into the collision between Cadeler’s Wind Orca and BG Orange at the Port of Tyne, which caused a crane collapse and damaged the container ship.

Ørsted expects three offshore wind projects totalling 2.5 GW to be commissioned in the second half of 2026 as construction advances across its offshore portfolio.

Cadeler has acquired Menck at an agreed EUR 501 million enterprise valuation, adding specialist offshore foundation installation equipment and engineering capabilities to its offshore wind T&I business.

EEW SPC is progressing Hornsea 3 monopile loadouts, moving foundations up to 93 m long and nearly 1,700 tonnes for onward transport to Teesworks and installation by Cadeler.
