Revised design and certification standards for floating wind sector
The documents can be applied for the design and certification of floating wind farms, floating wind turbines or their components
The two documents – DNV GL-ST-0119 and DNV GL-SE-0422 – define design and certification requirements for floating offshore wind turbine concepts, prototypes and projects. The guidelines provide the most comprehensive technical reference suite for this emerging technology, the classification society said, enabling the safe and reliable realisation of floating wind projects. The documents cover all aspect of the integrated wind farm system, including turbines and other components.
According to DNV GL’s recently published Energy Transition Outlook, the role of wind in the overall energy mix is likely to grow significantly over the coming decades. The classification society forecasts that by 2050, 12% of world primary energy supply will come from wind energy, and 20% of this will be generated by the offshore wind sector. In relative terms, DNV GL estimates that offshore wind will grow by a factor of 85 between 2016 and 2050, the same rate as the solar photovoltaic sector.
The classification society has developed the new guidelines based on experience from research projects and verification of existing floating wind prototypes and pilot wind farms. The society has also drawn on its long experience in the oil and gas and bottom-fixed offshore wind industry whilst also addressing specific floating wind challenges.
Kim Mørk, executive vice president, Renewables Certification at DNV GL, spoke of the ‘major global potential’ for harvesting offshore wind resources. “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,” Mørk said.
