The invention discloses an offshore foundation structure and an offshore wind turbine system. The offshore foundation structure includes a floating body, anchor chains and a plurality of spiral side plates. A first ballast tank is arranged in the floating body, and the first ballast tank is used for adjusting the draft of the floating body. One ends of the anchor chains are connected to the floating body, and the other ends of the anchor chains are used for being fixed to the bottom of the sea. The spiral side plates are arranged spirally on the outer wall of the floating body, so that all thespiral side plates form a spiral structure on the outer wall of the floating body. The offshore wind turbine system includes a wind turbine device and the offshore foundation structure. The floatingbody can float on the sea and adjust the draft of the offshore foundation structure through the first ballast tank. The anchor chains enable the offshore foundation structure to be located in a presetsea area. The spiral side plates form the spiral structure on the floating body, dispersion of wake vortexes caused by sea currents is facilitated, and the occurrence of vortex-induced motion causedby the sea currents can be suppressed to a certain extent; and in addition, the hydrodynamic damping of the offshore foundation structure can be further increased, and the motion performance of a windturbine installed on the offshore foundation structure can be optimized.

    本发明公开了一种海上基础结构及海上风机系统,海上基础结构包括浮体,浮体内设有第一压载舱,第一压载舱用于调节浮体的吃水深度;锚链的一端连接于浮体,锚链的另一端用于固定在海底;螺旋侧板设有多个,螺旋侧板呈螺旋排布于浮体的外壁,使所有的螺旋侧板在浮体的外壁形成螺旋结构;海上风机系统包括风机装置和前述的海上基础结构。浮体能够漂浮在海面上,并通过第一压载舱调整海上基础结构的吃水深度;锚链使海上基础结构位于预设的海域内;螺旋侧板在浮体上形成螺旋结构,有利于分散海流带来的尾流涡,能够在一定程度上抑制由于海流导致的涡激运动现象的发生,另外,也能增加海上基础结构的水动力阻尼,优化安装在其上的风机运动性能。
