Hywind Tampen foundations make a move

Developer Equinor has released a new video, ‘Hywind Tampen – on the move’, as the project’s concrete foundations are being shipped to the deepwater site at Donmersnes.

Aker Solutions has completed construction of the first twenty metres of the eleven spar-substructures at its yard in Stord. These are now being transported to Dommersnes where concrete slipforming will be completed. Slipforming work will continue to 107.5 metres: it is the first case of concrete slipforming for an offshore project in the Norwegian continental shelf.

The 88 MW Hywind Tampen is a floating wind farm, expected to supply electricity to the Snorre and Gulfaks offshore operations in the Norwegian North Sea. It will be the largest floating wind farm in the world, and the first ever to power oil & gas platforms, as well as being Equinor’s first floating wind project using concrete technology.

Despite the upheavals wrought by the COVID-19 pandemic, the project remains on time and on track, according to Equinor’s project director for Hywind Tampen, Olav-Bernt Haga. “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. This is a large and complex industrial project where we use our experience from oil and gas projects,” Haga explained.

Construction kicked off in October 2020, when the Prime Minister of Norway cut the first steel. This year, 2021, is what Equinor calls the project’s “year of manufacturing”, with all elements to be collected at Gulen, where they will be assembled in 2022. Once the wind farm is operational, Equinor will serve as operator, being in charge of operations and maintenance.

The eleven-turbine wind farm is expected to provide approximately 35% of the annual power needed by Snorre A and B and Gullfaks A, B, and C, while reducing Cos emissions by 200,000 tons a year. Equinor considers it “Hywind Tampen will be a test bed for further development of floating wind, exploring the use of new and larger turbines, installations methods, simplified moorings, concrete substructures and integration between gas and wind power generation systems.”
