Hornsea Two will surpass its predecessor Hornsea One by generating 1.4 GW of clean energy once complete in 2022. DEME’s offshore installation vessel ‘Innovation’ will be assisting at the wind farm location 89 km off the Yorkshire coast in the UK. ‘Pacific Orca’ will also begin works on location 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 the crane lifts and manoeuvres the heavy foundation components.

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.

“Even during these challenging times, we’re still able to take these important next steps towards the construction of this game changing wind farm” said Patrick Harnett, Hornsea Two Programme Director for Ørsted. “We’re extremely pleased to once again work alongside suppliers who share our vision for a greener world and look forward to the upcoming milestones that will continue to pave the way in terms of innovation for offshore wind.”

A selection of 30 transition pieces are being manufactured at EEW OSB’s factory in Teesside, with the first load out having recently been completed, whilst Danish based Bladt are supplying the additional 135 components.
