Hywind, World's First Floating Wind Farm, Being Built Off Scotland Coast
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.
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
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
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 kilometres off the shore.
The turbines can operate in water up to a kilometre deep.
The tower, including the blades, measure 175 metres in height, dwarfing Big Ben.
Each tower weighs 11,500 tonnes.
Each blade is 75 metres long – almost the wing span of an Airbus, the manufacturers said.
blades harness breakthrough software – which holds the tower upright by
twisting the blades to dampen motions from wind, waves and currents.
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.
on a sealed vase-like tube 78 metres deep, the turbine’s bottom filled
with iron ore to weight the base and keep it upright in the water.
