OSCILLATION REDUCTION DEVICE FOR FLOATING BODY STRUCTURE AND FLOATING BODY STRUCTURE
PROBLEM TO BE SOLVED: To provide an oscillation reduction device for a floating body structure which can reduce oscillation due to wave to a level with no problem on residence, and a floating body structure.SOLUTION: A device 16 for reducing oscillation of a floating body structure 10 provided on a water surface WL comprises: level maintaining means 22 comprising a piston cylinder 20 which is provided between an upper structure 12, which is provided on the water surface WL and constitutes at least a part of the floating body structure 10, and plural floating bodies 14 which support the upper structure 12 from below and float on the water surface WL or in water, and in which a fluid 18 is filled; and stability generation means 24 which generates a restitutive force for rotation of the upper structure 12 around a horizontal axis. A piston 30, which is located in each cylinder 26 of at least two sets of piston cylinders 20, is connected to a corresponding floating body 14, and both cylinders 26 are communicated with each other so that when one piston 30 is moved, the other piston 30 is moved in an opposite direction.SELECTED DRAWING: Figure 1
【課題】波浪による動揺を居住上問題ないレベルに低減することのできる浮体構造物の動揺低減装置および浮体構造物を提供する。【解決手段】水面ＷＬに設けられる浮体構造物１０の動揺を低減する装置１６であって、水面ＷＬ上に設けられ、浮体構造物１０の少なくとも一部をなす上部構造体１２と、この上部構造体１２を下側から支持して水面ＷＬまたは水中に浮かぶ複数の浮体１４との間に設けられ、内部を流体１８で満たしたピストンシリンダ２０からなるレベル維持手段２２と、水平軸回りの上部構造体１２の回転に対する復元力を発生する復原力発生手段２４とを備え、少なくとも２組のピストンシリンダ２０の各シリンダ２６内に配置されたピストン３０は対応する浮体１４に連結され、一方のピストン３０が動くと他方のピストン３０が反対方向に動くように両シリンダ２６は連通するようにする。【選択図】図１
