STAVANGER, Norway – The substructures for Equinor’s Hywind Tampen floating offshore wind project in the North Sea is now moving from Stord in Norway to the deepwater site at Dommersnes.
Here concrete slip-forming of the spar-substructures will be completed. According to the company, this will also be the first concrete slip-forming for a Norwegian offshore project since the Troll A platform was delivered in 1995.
The 11 floating concrete foundation substructures built by Aker Solutions at Stord are currently being towed to Vindafjord.
At Stord the first 20 m (65.6 ft) were built at the drydock site. Once the foundations are moored at Dommersnes in Vindafjord, concrete slip-forming will continue to a height of 107 m (351 ft).
The workscope at Dommersnes includes mechanical outfitting of the foundations prior to transportation to Gulen for installation of the wind turbines. The final phase of the project involves tow-out and installation offshore, to be performed under a 50/50 partnership with DOF Subsea.
Hywind Tampen is an 88-MW floating wind farm that will supply electricity to the Snorre and Gullfaks field operations in the Norwegian North Sea. This will be the first development of its type to power offshore oil and gas platforms, and Equinor’s the first floating wind project to employ concrete technology for wind projects.
The turbines’ steel anchors are currently being welded together at Aker Solutions yard in Verdal. The nacelles, blades, and turbine towers will be produced at sites elsewhere in Europe and then shipped to the Wergelands base in Gulen.
Next year all the components will be assembled at the site in Gulen using what Equinor believes is the largest crane ever deployed onshore in Norway.
The completed wind turbines will be transported to the offshore location in early summer 2022 with all related offshore work completed by the end of the year.
Equinor will be responsible for operation and maintenance of the wind farm.
