"Technology could help power a clean energy transition if it can overcome hurdles of cost, design and opposition from fishing"
"In the stormy waters of the North Sea, 15 miles off the coast of Aberdeenshire, in Scotland, five floating offshore wind turbines stretch 574 feet (175 metres) above the water. The world’s first floating windfarm, a 30 megawatt facility run by the Norwegian company Equinor, has only been in operation since 2017 but has already broken UK records for energy output.
While most offshore wind turbines are anchored to the ocean floor on fixed foundations, limiting them to depths of about 165ft, floating turbines are tethered to the seabed by mooring lines. These enormous structures are assembled on land and pulled out to sea by boats.
The ability to install turbines in deeper waters, where winds tend to be stronger, opens up huge amounts of the ocean to generate renewable wind power: close to 80% of potential offshore wind power is found in deeper waters. In addition, positioning floating turbines much further off the coast helps avoid conflicts with those who object to their impact on coastal views."
