ABSTRACT=Due to the existence of rotor and tower, the floating offshore wind turbine (FOWT) is subjected to larger wind heeling moment than the conventional floating platforms, which would cause significant pitch motion and bring great challenge to the structural safety and power generating efficiency. Moreover, the dynamic cable used for power transmission is sensitive to the horizontal motion of floating platform. Thus, it is essential to inhibit the pitch and horizontal motions. The floating offshore wind turbine is connected with seabed by the mooring system to resist the motions, while the conventional mooring system mainly resist the horizontal motions. An innovative type of mooring system was proposed to resist the pitch and horizontal motions simultaneously in this article. The motion responses and structural loads of FOWTs were calculated and compared under the effects of the conventional and innovative mooring systems. Additionally, the restoring forces and moments of two mooring systems were also given to better verify the motion inhibiting performances.
