DNV GL launches floating wind guidelines

GERMANY: Certification body DNV GL has published revised standards for the design of floating wind turbines and their structures.

The new guidelines cover the complete requirements for the integrated system — from the control of the single turbine and floater to mooring and anchors of the complete wind farm — and can be applied for design and certification.

They will ensure the safe and reliable realisation of floating wind projects, DNV GL stated.

Kim Mørk, executive vice president of renewables certification at DNV GL, said there was a "promising future" for floating offshore wind, with innovative concepts unlocking a major global potential for harvesting offshore wind and resources".

He added: "The technology is maturing and we have therefore revised the standard and launched the service document for floating wind turbines.

"We are confident that this will support further development of floating wind as a competitive technology for making the energy future safer, smarter and greener."

In its Energy Transition Outlook report, published earlier this month, DNV GL forecast that by 2050, 12% of the world’s primary energy supply will come from wind, of which 20% will come from offshore wind.

The certification body added that as new technologies, such as floating wind, grow in prevalence, it will be important to mitigate the risks of implementation to ensure safe and reliable performance.

To enable this for floating offshore wind, DNV GL developed the two new documents based on experience from research projects and verification of existing floating wind prototypes and pilot wind farms.

The technical guidelines for turbines and structures are also built on DNV GL’s experience in the oil and gas and bottom-fixed offshore wind industry by referencing proven standards, as well as addressing challenges specific to floating offshore wind.
