The invention provides a floating type offshore wind turbine system, and relates to the field of offshore wind turbines. The floating type offshore wind turbine system comprises a wind turbine generator set, a tower drum, a floating type platform and an anchoring system. The floating type platform comprises a buoyancy tank assembly and a ballast tank assembly arranged on the lower side of the buoyancy tank assembly. The buoyancy tank assembly comprises a central buoyancy tank, at least three corner point buoyancy tanks which are distributed at intervals in the circumferential direction and a connecting buoyancy tank, the ballast tank assembly comprises a central ballast tank, at least three corner point ballast tanks which are distributed at intervals in the circumferential direction and a connecting ballast tank; the buoyancy tank and the ballast tank are connected through a truss type round pipe or a cylindrical structure, and a fixed ballast body is further arranged on the lower portion of each corner point ballast tank. The buoyancy tank assembly provides large buoyancy to improve the buoyancy center, and the bottom large-area ballast tank assembly and the fixed ballast body lower the gravity center, so that the gravity center of the whole structure system is lower than the buoyancy center, the still water deflection recovery rigidity is effectively increased, and the stability and the movement performance of the floating type wind turbine system are improved.

    本发明提供了一种漂浮式海上风机系统,涉及海上风机领域。漂浮式海上风机系统包括风电机组、塔筒、浮式平台和锚泊系统,浮式平台包括浮力舱组件和布置在浮力舱组件下侧的压载舱组件;浮力舱组件包括中心浮力舱、至少三个周向间隔分布的角点浮力舱以及连接浮力舱,压载舱组件包括中心压载舱、至少三个周向间隔分布的角点压载舱以及连接压载舱;浮力舱和压载舱之间通过桁架式圆管或圆柱结构进行连接,角点压载舱的下部还设有固定式压载体。通过浮力舱组件提供大浮力来提高浮心,通过底部大面积压载舱组件和固定式压载体来降低重心,从而使整个结构系统的重心低于浮心,有效增大了静水偏转恢复刚度,提高了漂浮式风机系统的稳定性和运动性能。
