Workers in Bilbao, Spain have begun assembling two giant concrete cylinders to form the base of the country’s first floating offshore wind turbine, due for installation this fall in 85 m of water.
Last month, contractor Ferrovial Construccíon S.A. used two 500-tonne capacity crawler cranes to raise and rotate six vertically cast floater elements and transport them 150 m to an assembly platform to be joined together.
