Abstract: The present disclosure relates to systems and methods for rotating a floating platform. An example method includes determining a desired position of a floating platform in a yaw axis. The floating platform is fixed by an anchor leg to an underwater attachment point. The method includes receiving, from a position sensor, information indicative of an actual position of the floating platform in the yaw axis. The method also includes rotating the floating platform in a desired direction about the yaw axis based on the desired position and the actual position. Optionally, the floating platform may include a yaw member and an environmental sensor. In such scenarios, the method may include receiving information about a prevailing wind direction or water current direction. The method may include causing the actuator to adjust the yaw member based on at least one of: the prevailing wind condition or the prevailing water current direction.
