The invention relates to a triple-hulled vessel type offshore floating wind power foundation which comprises a main body, two side sheet bodies, a connecting structure, a wind power tower drum and a wind turbine generator. The main body and the two side sheet bodies are of slender structures, the two side sheet bodies are symmetrically arranged on the two sides of the main body, and the two side sheet bodies are connected to the main body through connecting structures to form a triple-hulled vessel; an inner rotating tower is arranged on a bow of the main body, and the triple-hulled vessel is provided with a single-point mooring system through the inner rotating tower; the wind power tower drum is arranged on the main body and used for supporting the wind turbine generator. The three-hulled ship type platform structure is adopted, under the condition that the stability of the platform is guaranteed, the pitching recovery rigidity is larger than that of a semi-submersible type platform, and the pitching motion performance of the platform is improved. And meanwhile, the side sheet body provides sufficient rolling return rigidity for the platform, so that the rolling motion performance of the platform is ensured. A single-point mooring system is adopted for positioning, the flag effect can be brought into full play, and the environmental load borne by the floating platform foundation is effectively reduced.
本发明涉及一种三体船式海上浮式风电基础,包括主体、两个侧片体、连接结构、风电塔筒和风电机组;主体和两个侧片体均为细长结构,两个侧片体对称布置于主体的两侧,两个侧片体分别通过连接结构连接于主体形成三体船;主体的船艏设有内转塔,三体船通过内转塔设置单点系泊系统;风电塔筒设于主体上,风电塔筒用于支撑风电机组。本发明采用三体船式平台构型,在保证平台稳定性的情况下,较半潜式平台具有更大的纵摇回复刚度,提高了平台的纵摇运动性能。同时侧片体为平台提供了充足的横摇回复刚度,保证了平台的横摇运动性能。采用单点系泊系统进行定位,可以充分发挥旗帜效应,有效降低浮式平台基础所受到的环境载荷。
