Floating wind uses the same turbines as conventional ‘seabed-fixed’ offshore wind but they are deployed on top of floating structures that are secured to the seabed with mooring lines and anchors. Electricity is transmitted to shore via subsea cables.
This technology opens up the possibility of deploying offshore wind projects in regions with deeper waters in established markets like the UK and France, and also in new regions like Japan and the west coast of the USA.
As a less mature technology than seabed-fixed, floating wind is currently more expensive but costs are expected to fall rapidly so that it should be relatively cost competitive by 2030.
