Floating wind turbine foundation and floating wind turbines

The present invention provides a floating wind turbine foundation and a floating wind turbine, comprising a floating platform and a mooring system, a floating platform through the fairlead is fixedly connected to the mooring system, characterized in that said floating platform comprises a float, the float is provided with a plurality of fairlead, the fairlead and the mooring system is connected to mooring lines, the mooring cable to said connecting end into a first fairlead bifurcation and second branch, the first branch and the second branch are connected to two fairleads on the pontoon. Pontoon floating platform and ballast tanks effectively increases the distance between the center of gravity and buoyancy, thereby effectively increasing the rigidity of the recovery rotation, near the water surface using a small cross-sectional area of ​​the cylinder barrel near effectively reduces the wave forces at the water surface size, while the mooring lines can effectively limit the delta yaw movement between the floating platform's navigation through hole and the floating platform.
