To provide an understructure for floating type offshore wind power generation, etc., applicable for upsizing and capable of suppressing thickening of plate thickness.SOLUTION: An understructure for floating type offshore wind power generation 1 is a basic structure for supporting a wind power generation device 3 in a state of being floated on the ocean. The understructure for floating type offshore wind power generation 1 has a wind power generation device 3 arranged above an upper floor slab 5 of the understructure for floating type offshore wind power generation 1 in a state of floating on the ocean to have the longitudinal direction face the vertical direction. The understructure for floating type offshore wind power generation 1 is mainly composed of a cylindrical structure 7, the upper floor slab 5, and a lower floor slab 9, etc.. The lower floor slab 9 is joined to lower ends of the plurality of cylindrical structures 7, and the upper floor slab 5 is joined above. That is, a plurality of cylindrical structures 7 are fixed by the upper floor slab 5 and the floor slab 9 and a sealed space is formed inside the cylindrical structure 7. In addition, the wind power generation device 3 is attached to the upper floor slab 5.SELECTED DRAWING: Figure 1
【課題】 大型化にも適用可能であり、板厚の厚肉化を最小限に抑制することが可能な浮体式洋上風力発電用下部構造等を提供する。【解決手段】 浮体式洋上風力発電用下部構造1は、風力発電装置3を洋上に浮かべた状態で支持するための基礎構造である。浮体式洋上風力発電用下部構造1は、長手方向が鉛直方向に向くように洋上に浮いた状態で、風力発電装置3が浮体式洋上風力発電用下部構造1の上床版5の上方に配置される。浮体式洋上風力発電用下部構造1は、主に、筒状構造体7、上床版5、下床版9等によって構成される。複数の中空の筒状構造体7の下端には下床版9が接合され、上方には上床版5が接合される。すなわち、上床版5とした床版9とで、複数の筒状構造体7が固定され、筒状構造体7の内部には、密閉された空間が形成される。また、風力発電装置3は、上床版5に取り付けられる。【選択図】図1
