New floating wind projects at Norwegian test centre eye 15MW-plus turbines

Testing of three platforms with larger machines relevant for future of floating offshore wind, industry group says

Three new floating offshore wind projects have signed contracts with Norway’s METCentre to test rigs topped by 15MW-plus turbines, Norwegian Offshore Wind said without naming companies or platform types.

The industry group stressed turbine sizes above 15MW will be relevant for future floating offshore wind farms, and claimed no other places in the world could carry out testing at this scale.

The world's first floating offshore wind turbine, the 2.3MW Hywind Demo, is already located at the site, and in 2021 it was joined by the Stiesdal-developed TetraSpar platform equipped with a 3.6MW Siemens Gamesa turbine. There is space for seven turbines in total – which together can produce up to 85MW – at the site off Norway’s west coast just a few kilometres away from the Utsira Nord (North) areas, where the country’s first commercial floating wind farm will be located.

“This is very good news for innovation in floating offshore wind,” said Arvid Nesse, head of METCentre and Norwegian Offshore Wind.

“The technologies now being planned at METCentre will be crucial when we get started with Utsira Nord.”

After some delays, the government now plans to hold the 1.5GW Utsira Nord tender next year, and on Monday confirmed it will make NKr35bn ($3.29bn) in support available for one of its two sites, Vestavind F or Vestavind B – an amount deemed too low by the sector.

The new test projects at METCentre are all competing for funding by state-owned enterprise Enova and are therefore currently confidential, Norwegian Offshore Wind said.

“We are the only place in the world ready with permits to test projects of this capacity,” Nesse said.

“If we are to get floating offshore wind started in Norway without further delays, it must begin at METCentre, so we can gain important knowledge from both the construction and operation processes, and thereby achieve the necessary cost reductions before Utsira Nord.

“To ensure diversity in both the supply chain and technology, we believe it is crucial that these three projects all receive support so that they can be realized before the start of Utsira Nord.”

Testing and demonstration projects significantly contribute to reducing the cost of floating wind, he added.
