Abstract Dynamic response of a Floating Offshore Wind Turbine (FOWT) with Spar-type floating
foundation is presented. The FOWT mounts a 100kW down-wind turbine, and is grid-connected. It was installed on June 11th, 2012 for the purpose of the demonstration experiment. During the experiment, the FOWT was attacked by Sanba (international designation: 1216), the strongest tropical typhoon worldwide in 2012. The central atmospheric pressure was 940 hPa when it was close to the FOWT, and the maximum significant wave height of 9.5m was recorded at the site. In this paper, the dynamic responses of the platform motion, the stresses at the tower sections and the chain tensions during the typhoon event, Sanba (1216), have been analyzed, and compared with the measured data.
