The Norwegian company Wind Catching Systems (WCS) has received Approval in Principle (AiP) from the classification society DNV for its wind catcher design.
Instead of individual large wind turbines, many smaller rotors are connected together in this new type of turbine. One such “wall” is expected to generate 40 MW of electricity.
According to WCS, the AiP represents an important milestone on the way to commercial demonstration of the technology. Several partner companies helped to carry out simulations and build models to advance the concept. The Windcatcher technology had to consider several factors to achieve the AiP, including structure, stability, hydrodynamics, mooring system placement and others. In addition, WCS conducted a model test campaign in Måløy to study the behaviour of the windcatcher under different wave conditions.
“Windcatcher” was first presented in 2021
The 40 MW installation will be the first of four planned turbines in the project. Now comes the next step: WCS has applied for a license for a demonstration project off the coast of Øygarden via its subsidiary Wind Catching Demo.
The wind catcher technology was first presented in 2021 and is still in its early stages. The main difference to conventional offshore turbines is that smaller turbines are connected together and can be replaced if necessary without special equipment. The floating turbines are expected to have a service life of up to 50 years and reduce land consumption for wind energy by more than 80%.
