Aker Solutions has this week started transporting the 11 spar substructures for Equinor’s 88MW Hywind Tampen Hywind Tampen (88MW) Offshorebetween the Gullfaks and Snorre fields, Norway, Europe Click to see full details floating offshore wind project to deep water.

In a series of firsts, Hywind Tampen in Norwegian waters will be the world’s largest floating offshore wind farm and the first to power offshore oil and gas platforms. It is also Equinor’s first floating wind project to use concrete technology. 

“The project represents a direct transfer of technology from oil and gas to renewables,” said Olav-Bernt Haga, Equinor’s project director for Hywind Tampen.

The 11 floating concrete hulls that will carry the wind turbines are being built at Stord and Dommersnes in south-west Norway, while the steel anchors are being welded together at contractor Aker Solutions’ yard at Verdal in the north-west. 

The nacelles, blades and turbine towers will be manufactured in mainland Europe and shipped to Gulen on the central west coast, where the substructures will be towed once the slipforming and mechanical completion work is completed at Dommersnes.

“We plan to start towing the completed wind turbines to Tampen early summer of 2022 and complete the offshore work by the end of the year,” said Haga. 

Hywind Tampen will supply electricity to the Snorre and Gullfaks offshore field operations in the Norwegian North Sea.
