Offshore wind has become a staple of renewable energy production. But so far it has been mostly limited to shallow waters, restricting how many countries can take advantage of it. That could soon change thanks to floating wind. The technology consists of a turbine mounted on a buoyant substructure and anchored to the seabed with chains. This means it can be deployed in seas of 300 metres deep and more, compared to the more traditional system of mounting turbines on the seabed, which becomes uneconomical in depths of more than 60 metres. Because it allows wind production in deeper waters, the t…
