Contribution to Conference
With regard to the offshore areas in China, the water depth is limited so that the traditional Spar-type FOWTs are not suitable to be installed in these areas. In this work, we proposed a novel reduced draft Spar-type FOWT with anti-motion damping structure. Simulations are conducted in both frequency and time domain to investigate the dynamic response of the FOWT in different scenarios. Towards this end, a coupled aero-hydro-mooring numerical model is developed. The methodology includes a blade-element-momentum model for aerodynamics, a nonlinear model for hydrodynamics, a nonlinear restoring model of SPAR buoy, and a nonlinear catenary model for mooring cables. The motions of platform, the tensions in the mooring lines and the power generation performance are documented in different cases. The dynamic performance is also compared with the classic Spar-type wind turbine. According to the results, it shows that the reduced draft Spar-type FOWT is effective to support the 5MW baseline offshore wind turbine in the limited water-depth area. The increase in diameter of the motion reducing structure can effectively reduce the motion in pitch and the mooring tension, thereby improving safety and stability of the floating turbine system.
