Norwegian floating wind platform developer Odfjell Oceanwind has received a Basic Design Approval (BDA) from DNV for its Deepsea Star semi-submersible floater design.
The approval applies to the use of the design with the SG 14‑236 DD 15 MW turbine from Siemens Gamesa across various offshore conditions.
The approval, granted per DNV-RU-OU-0512, confirms the Deepsea Star design meets the DNV-ST-0119 standard, covering steel material strength, corrosion protection, stability, mooring, and electrical systems, according to Odfjell Oceanwind on 11 November.
“Our Basic Design Approval for the Deepsea Star floating foundation builds on an earlier concept validation and confirms the design’s compliance with recognized industry standards. This design has also been verified by additional independent analyses, increasing confidence in the review,” said Sille Grjotheim, Global Segment Director Floating Offshore Wind at DNV.
The company announced Deepsea Star in February 2023 as a column-stabilised semi-submersible platform with a center tower, designed for wind turbines of 15 MW and larger.
“The BDA provides certainty to safety regulators, banks, insurance companies, developers, and suppliers that the Deepsea Star design can be trusted and thereby contributes to its overall bankability. We expect this form of certification to be instrumental in the journey of safely bringing down costs and making floating offshore wind relevant in the future energy mix,” said Per Lund, CEO of Odfjell Oceanwind.
In February 2024, the Norwegian company and Prodtex established a joint venture, Windsteel Technologies, to mass-produce floating wind foundations, including the Deepsea Star.
In March 2024, state funding of NOK 2 billion (about EUR 175 million) was awarded to the GoliatVIND project, which plans to utilize five 15 MW turbines on Deepsea Star foundations.
This year, Odfjell Oceanwind acquired Ørsted’s 80% stake in the 100 MW Salamander floating wind project in Scotland, adopting the Deepsea Star semi-submersible foundation for its turbines.
