To suppress part of relative motion between a floating body and a superstructure.SOLUTION: A swing suppression device coupling a floating body with a superstructure arranged above the floating body as well as suppressing part of relative motion between the floating body and the superstructure, includes a first coupling device for coupling the floating body and the superstructure to be capable of relative displacement. The first coupling device includes: a first energizing member having an axis extending in the horizontal direction to the floating body as an axis X, an axis orthogonal to the axis X and extending in the horizontal direction as an axis Y, and an axis extending in the vertical direction as an axis Z, and having a horizontal component in the extending direction, in parallel with the axis X or the axis Y, as well as including a plate spring for generating energizing force in the axis Z direction; a first support unit for supporting the first energizing member to one of the floating body and the superstructure; and a second support unit for supporting the first energizing member to the other of the floating body and the superstructure.SELECTED DRAWING: Figure 1
【課題】浮体と上部構造物との相対的な運動の一部を抑制する。【解決手段】浮体と、浮体の上方に配置される上部構造物とを連結するとともに、浮体と上部構造物との相対的な運動の一部を抑制する、動揺抑制装置であって、浮体と上部構造物とを相対変位可能に連結する第1連結装置を備え、第1連結装置は、浮体に対して水平方向に延びる軸をX軸、水平方向に延びる軸であるとともにX軸に直交する軸をY軸、上下方向に延びる軸をZ軸として、延びている方向の水平成分がX軸またはY軸に平行であるとともに、Z軸方向の付勢力を発生させる板バネを含む第1付勢部材と、浮体および上部構造物のいずれか一方に対して、第1付勢部材を支持する第1支持部と、浮体および上部構造物のいずれか他方に対して、第1付勢部材を支持する第2支持部と、を有する動揺抑制装置とする。【選択図】図1
