Offshore floating wind farms using one support platform that doubles as cryogenic storage costs less than $ 1m/MW. The wind machines have no need for costly yaw mechanisms since the entire support structure weathervanes into the wind as it is anchored to the sea floor using a single anchor line. They are dry-docked at sea, eliminating the need to come back to land for maintenance. The support structure will stock all the parts needed to maintain the wind machines. The V-shape of the flotation platform produces the calm water environment within the structure needed for birthing LNG class tankers for the loading and offloading of the liquid air.
