To reduce oscillation of the floating body structure as well as reducing mooring tension working on a mooring line.SOLUTION: A floating structure 2 moored to a water bottom 92 by a mooring line includes a floating body 21 long in the front to back direction connected to the mooring line on over-wave side. Thus, drag coefficient of the floating body 21 is capable of being reduced. As a result, mooring tension working on the mooring line 4 is capable of being reduced. In addition, a through hole 211 is provided going through the floating body 21 in the width direction as well as spreading vertically to water surface 91 in the floating structure 2. A central position C in the front to back direction of the through hole 211 is positioned more to back side of center of buoyancy F of the floating body 21. Thus, characteristic period of oscillation of the floating structure 2 is capable of being increased. As a result, resonance with waves is suppressed and the oscillation of the floating structure 2 is capable of being reduced.SELECTED DRAWING: Figure 2

    【課題】浮体構造物の動揺を低減するとともに、係留ラインに対して作用する係留張力を低減する。【解決手段】係留ラインにより水底92に係留される浮体構造物2は、波上側において係留ラインに接続される前後方向に長い浮体本体21を備える。これにより、浮体本体21の抗力係数を小さくすることができる。その結果、係留ライン4に対して作用する係留張力を低減することができる。また、浮体構造物2では、浮体本体21を幅方向に貫通するとともに水面91の上下に亘って広がる貫通孔211が設けられる。貫通孔211の前後方向の中心位置Cは、浮体本体21の浮心Fよりも後側に位置する。これにより、浮体構造物2の動揺の固有周期を増大させることができる。その結果、波浪との共振を抑制し、浮体構造物2の動揺を低減することができる。【選択図】図2
