The world’s very first floating fullscale offshore wind turbine has officially been inaugurated in the North Sea off the coast of Norway.
The turbine even has a name: Hywind. It measures 213 feet tall and weighs 5,300 tonnes, and it rests on a floating stand which is filled with water and rocks to provide balast. Three powerful cables anchor the stand to the seafloor.

nowBuzz up!StatoilHydro, the corporate energy giant which owns Hywind, plans to use it as a test for the next two years before building any more floating wind turbines. But if everything runs smoothly, they hope to set up floating turbines around the world for international partners, locations which are likely to include California, Japan, South Korea and Spain.

The biggest advantage to floating turbines is that they can operate out at sea at depths between 120 and 700 metres, much deeper than conventional offshore turbines. Winds are usually much stronger in deeper seas, meaning the new technology could also generate a lot more power.

And for those people who find wind turbines aesthetically unpleasing, floating turbines put further out to sea also mean they’ll be out of sight.

Currently floating turbines are significantly more expensive to build, but due to their many advantages, StatoilHydro believes that the costs should come down over time. “Our goal is to bring down the price to the level of fixed wind turbines that are currently installed in waters some 60 metres deep,” said Anne Stroemmen Lycke from StatoilHydro.

Hywind should begin fanning over the North Sea and generating electricity within the next couple of weeks.
