FLOATING STRUCTURE

To provide a floating structure capable of avoiding the influence of wave motion on a water surface as much as possible and capable of controlling with a low power.SOLUTION: A floating structure 1 of this embodiment comprises a main structure 10, and multiple auxiliary structures 20A, 20B, 20C, 20D connected to the main structure 10 and provided so as to surround the main structure 10 in a plan view. The main structure 10 has a main body 11 located in the water in an usage state, and an extension part 12 with the same thickness as the main body 11 or thinner than the main body 11, extending upward from the main body 11, and protruding from the water surface. The multiple auxiliary structures 20A, 20B, 20C, 20D give a moment or a thrust to the main structure 10 by mutually, cooperatively operating.SELECTED DRAWING: Figure 1 【課題】水面上の波動の影響を可及的に回避して低動力で制御可能な浮体構造物を提供する。【解決手段】実施形態の浮体構造物１は、主構造体１０と、この主構造体１０に接続され、平面視で主構造体１０を取り囲むように設けられた複数の補助構造体２０Ａ，２０Ｂ，２０Ｃ，２０Ｄとを備え、主構造体１０は、使用状態において水中に位置する本体部１１と、本体部１１と同じ太さか本体部１１よりも細く、本体部１１から上方に向けて延在し水面から突出する延在部１２とを有し、複数の補助構造体２０Ａ，２０Ｂ，２０Ｃ，２０Ｄは、互いに協調動作することにより主構造体１０にモーメントまたは推力を付与する。【選択図】図１
