Video: Novel design to make floating wind competitiveS. Himmelstein | September 07, 2021
The way wind farms are constructed, look and perform is reinvented with floating multi-turbine technology developed by Norwegian company Wind Catching Systems.
The Wind Catcher diverges from the conventional wind turbines consisting of one pole and three gargantuan blades: the new system is realized as a square grid with over 100 small blades. At 1,000 ft high, the structure is over three times as tall as an average wind turbine and stands on a floating platform anchored to the ocean floor.
The design overcomes the limits posed by standard offshore wind turbines that must be driven into the seabed and are therefore confined to water depths up to 200 ft and sites within 20 miles of shore. The floating structure will include several 1 MW turbines, each with blades 50 ft long and completing more rotations per minute relative to standard units, therefore generating more energy.
The technology is expected to reduce acreage use by more than 80%, have a 50-year service life and increase efficiency significantly in comparison to conventional floating offshore wind farms. The developers plan to build a prototype in the North Sea in 2022.
