The VAWT (vertical axis wind turbine) has advantages in the development of large-scale offshore wind power. This paper presents a motion study of a 5MW floating VAWT composed of the Φ type Darrieus wind turbine and the spar type floating foundation with heave plates. A computing code of aerodynamic loads was developed considering the dynamic stall and the floating foundation motions. The motion equations...
This paper presents the heave motion of a truss Spar platform in regular waves considering the dynamic coupling between the motions of the platform and water in the moon pool. For a spar platform with semi-closed moon pool, water can flow freely through the guide plate at bottom of the moon pool. The mass of water inside the moon pool is comparable to the platform mass itself if the top tension riser...
