The invention relates to the technical field of offshore wind power generation, and discloses a clamped floating type offshore wind power foundation platform which comprises a floating structure and a clamped structure. The fixed supporting structure is located below the floating structure and arranged underwater in a submerged mode, and the fixed supporting structure is suitable for providing bearing capacity and anti-overturning capacity for the floating structure. The floating structure floats on the water surface so as to be suitable for installing and placing wind power equipment, and the anti-tilting capacity can be improved through the water plane and the gravity center-buoyancy center height difference. The fixed supporting structure limits the horizontal displacement of the floating structure, adjusts the overall gravity center of the offshore wind power foundation and provides the anti-overturning capacity. The clamped floating type offshore wind power foundation platform has multiple composite stability sources, anchor chain mooring structures are reduced on the premise that the foundation stability is guaranteed, then the occupied area is reduced, the composite stability design is adopted, the situation that the structure size is too large due to a single stability source is avoided, steel materials are further reduced, the weight of the structure is reduced, and the cost is reduced. Therefore, the overall cost and the cost per kilowatt-hour are greatly reduced.
本发明涉及海上风电发电技术领域,公开了一种固支浮式海上风电基础平台,包括:浮式结构和固支结构;所述固支结构位于所述浮式结构的下方且潜设于水下,所述固支结构适于为所述浮式结构提供承载力和抗倾覆能力。浮式结构浮于水面以适于安装放置风电设备,可通过水线面和重心‑浮心高差提高抗倾能力;固支结构限制浮式结构的水平位移,调节海上风电基础整体重心,并提供抗倾覆能力。该固支浮式海上风电基础平台具有多重复合稳性来源,在保证基础稳定性前提下,减少锚链系泊结构,进而减少占地面积,并且采用复合稳性设计避免了单一稳性来源造成的结构尺寸过大,进一步减少钢材料,降低结构的重量,从而大幅度降低整体造价以及度电成本。
