A Floating Wind Turbine, For Easy Installation

“A startup in Norway thinks it might have a solution [to offshore wind power]. Called WindFlip, the idea is to use a lightweight barge to float the turbine horizontally to the site, and then erect it by letting in water at one end, allowing the turbine to rise into the air, with the device still attached. Once securely tethered, the WindFlip is then filled with air, releasing it again to the water, ready for the next installation.
Although still at the prototype stage, WindFlip potentially allows developers to reach sites more quickly, and to install turbines without needing crane equipment. [Ane Christophersen, WindFlip’s general manager,] says the WindFlip can travel at about eight knots, compared with a vertically driven barge which goes only at one knot, because of the drag in the water.”
