Foundation installation is underway at Ørsted’s Hornsea Two offshore wind farm 89km off the Yorkshire coast in the North Sea.

Foundation installation is being completed using DEME Group’s offshore installation vessel,
Innovation. Besides Innovation, Pacific Orca will also be out to work on site next year to support construction. Both are heavy-lift jack up vessels which have legs that can securely fix the ship to the seabed, raise the vessel from the water whilst onboard cranes lift and manoeuvre the heavy foundation components. The expectation is that the Innovation will complete 40-50 foundations, before handing over to the Pacific Orca, which is chartered by DEME.

In total, 165 monopiles and transition pieces will be installed at sea in preparation for the site’s 8.4 MW turbines. With a height from sea level to blade tip of 204 metres, the turbines will also feature new 82 metre long blades, which are currently being fabricated at the Siemens Gamesa Renewable Energy blade factory in Hull.

EEW SPC is supplying the projects 165 monopiles with Bladt is suppling the 135 of the transition pieces. The remaining 30 transition pieces are being manufactured at EEW OSB’s factory in Teesside.


Patrick Harnett, Ørsted Senior Programme Director for Hornsea Two said: “Our dedicated teams and contractors continue to overcome obstacles and perform above and beyond expectations. This offshore installation is another huge accomplishment for the Hornsea Two project and proves the commitment and hard work from everyone working towards the same goal – to create a world that runs entirely on green energy, through the safe and efficient construction of another of the world’s largest offshore wind farms.”

Hornsea Two will surpass its predecessor Hornsea One, by generating 1.4 GW of clean energy once complete in 2022. The project will span an offshore area of 462km² featuring 165 SG 8.0-167 DD turbines. It is expected to power well over 1.3 million homes in the UK with clean electricity.
