DNV certification secured for 22-MW floating wind foundation

The design for the foundation for floating wind turbines was validated by DNV using the IEA-22-280-RWT 22-MW generic reference turbine, and the company now plans to construct a reduced-scale version of the substructure for testing.

“This phase will be pivotal in demonstrating the design’s constructability and how well it can be industrialised, addressing the main challenges identified during the concept certification phase, and paving the way for large-scale deployment,” the company said.

“Certification, awarded by one of the leading certification companies, is a significant milestone in the development of BayFloat and in advancing floating offshore wind turbine technology,” said BayWa r.e. 

The certification process – conducted in accordance with DNV-SE-0422:2021-09 ‘Certification of floating wind turbines,’ including DNV-ST-0119:2021-06 ‘Floating wind turbine structures’ – involved rigorous assessment by DNV. The assessment concluded that the BayFloat concrete substructure and mooring system are feasible for further development and qualified them for concept-level certification.

BayWa r.e. technical director offshore wind Ricardo Rocha said, “This milestone is a testament to the hard work and dedication of our team and our engineering consultant, Ramboll, who supported us while progressing our original patented concept through development and optimisation. 

“Certification not only validates the maturity of BayWa r.e.’s proprietary floating wind substructure, it also demonstrates its readiness for industrial-scale deployment. It further underscores BayFloat’s potential for project-specific optimisation, enabling adaptation to existing port infrastructure and locally available supply chains in a cost-efficient manner.”
