Patent ID: 8053916

Claim:
A floatable platform comprising: a platform base; a motion sensor for determining the axial motion of said platform about or along one or more axes; a stability controller; a tower; a wind turbine mounted upon said tower, said turbine having a propeller and a rotational mount upon which said turbine is mounted for rotational movement about a longitudinal axis of said tower; said motion sensor including a yaw detector for detecting the angular yaw position of the platform and being operably connected to said stability controller for supplying yaw data to said controller; and a yaw actuator for varying the yaw angle of the turbine relative to said tower and in response to said angular yaw position of said platform, said yaw activator being operably connected to said stability controller for receiving actuation signals therefrom, thereby to vary the angular position of said wind turbine relative to said tower such that said platform rotates about its vertical axis to reduce said angular yaw of said platform.
