World’s first floating wind farm being built off Scotland coast

The world's first full-scale floating wind farm, named Hywind - with turbines taller than the Britain's Big Ben - is being built off the coast of Scotland. The technology will allow wind power to be harvested in waters that are too deep for the existing bottom-standing turbines.

The world’s first full-scale floating wind farm – with turbines taller than the Britain’s Big Ben – is being built off the coast of Scotland. The technology will allow wind power to be harvested in waters that are too deep for the existing bottom-standing turbines. The wind farm, known as Hywind, is a trial project which will bring power to 20,000 homes.

The output from the turbines is expected to surpass generation from current ones, according to the Norway-based manufacturer Statoil. “This is a tech development project to ensure it’s working in open sea conditions. It’s a game-changer for floating wind power and we are sure it will help bring costs down,” said Leif Delp, project director for Hywind.

The huge turbines are currently being moved into place. One giant turbine has already placed, while four more wait in a Norwegian fjord. By the end of the month all the turbines will be towed to 25 kilometers off the shore.

The turbines can operate in water up to a kilometer deep. The tower, including the blades, measure 175 meters in height, dwarfing Big Ben. Each tower weighs 11,500 tonnes, the ‘BBC News’ reported. Each blade is 75 meters long – almost the wing span of an Airbus, the manufacturers said. The blades harness breakthrough software – which holds the tower upright by twisting the blades to dampen motions from wind, waves and currents.

The operation to begin shifting the first of the 11,500 tonne giants involved the crew securing thick cables to tug boats and using remote-controlled submarines to check for obstacles. Floating on a sealed vase-like tube 78 meters deep, the turbine’s bottom filled with iron ore to weight the base and keep it upright in the water.

    Is bigger necessarily better? here is a link to our research study on the topic of wind turbine's efficiencies : : ertekprojects /url/b Also, How about the risks of failures and accidents? here is a link to our research on wind turbine accidents: : ertekprojects /wind-turbine-accidents/ Please feel free to contact me for your feedback on our studies, Best Regards, Dr. Gurdal Ertek
