To provide a lower structure for floating offshore wind power generation which is also applicable to larger sizes and can reduce a moment generated at a lower end of a tower or the like.SOLUTION: A lower structure 1 for floating wind power generation is a fundamental structure for supporting a wind power generator 3 in a state of being floated on the sea. In the lower structure 1 for floating wind power generation, the wind power generator 3 is arranged above an upper floor plate 5 of the lower structure 1 for floating wind power generation in a state of being floated on the sea. The lower structure 1 for floating wind power generation is mainly formed of cylindrical structures 7, the upper floor plate 5, a lower floor plate 9 or the like. The lower floor plate 9 is joined to lower ends of a plurality of hollow cylindrical structures 7, and the upper floor plate 5 is joined over the cylindrical structures. Thus, the plurality of cylindrical structures 7 are fixed by the upper floor plate 5 and the lower floor plate 9, and sealed spaces are formed inside the cylindrical structures 7.SELECTED DRAWING: Figure 1
【課題】 大型化にも適用可能であり、タワー等の下端に生じるモーメントを低減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、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。【選択図】図1
