PROBLEM TO BE SOLVED: To provide an oscillation reduction apparatus of the mooring floating body capable of sufficiently reducing even the long cycle oscillation and the mooring floating body.SOLUTION: It is an oscillation reduction apparatus 2 of the work barge 1 moored in the floating state on the water. It comprises the resistance part 3 suspended from the side part 11 of the work barge into water, the mooring wire 4 one end of which is connected to the resistance part, the rotating body 5 attached to the side part of the work barge and changing the mooring wire direction above the resistance part, the fixed pulley group 6 attached to the side part of the work barge in the position separated from the rotating body, the moveable pulley group 7 arranged below the fixed pulley group and the weight part 8 connected to the moveable pulley group and grounded on the water bottom G. Here, the mooring wire is bridged to the moveable pulley group through the fixed pulley group after changing its direction by the rotating body, is bridged multiple times between the fixed pulley group and moveable pulley group and its end is connected to the fixed pulley group side or the moveable pulley group side.SELECTED DRAWING: Figure 1
【課題】長周期の動揺であっても充分に低減可能な係留浮体の動揺低減装置及び係留浮体を提供する。【解決手段】水上に浮いた状態で係留される作業船1の動揺低減装置2である。そして、作業船の側部11から水中に吊り下げられる抵抗部3と、抵抗部に一端が接続される係留ワイヤ4と、作業船の側部に取り付けられて抵抗部の上方で係留ワイヤの方向を転換させる回転体5と、回転体から離隔した位置の作業船の側部に取り付けられる定滑車群6と、定滑車群の下方に配置される動滑車群7と、動滑車群に接続されて水底Gに着底させる錘部8とを備えている。ここで、係留ワイヤは、回転体で方向転換された後に定滑車群を通って動滑車群に架け渡され、定滑車群と動滑車群との間で複数回の架け渡しがされて定滑車群側又は動滑車群側に端部が接続される。【選択図】図1
