To provide an oscillation estimating method of a suspended load capable of estimating oscillation of a suspended load in a semi-submerged state, suspended by a crane installed on a floating body.SOLUTION: An oscillation estimating method of a suspended load calculates the fluid force that a floating body 1 receives from a wave W, the force that the floating body 1 receives from a surrounding water mass when it oscillates due to the wave W, the fluid force that a suspended load 4 in the semi-submerged state receives from the wave W, and the force that the suspended load 4 in the semi-submerged state receives from the surrounding water mass when it oscillates due to the wave W using wave information in the target water area where the floating body 1 and the suspended load 4 suspended by a crane 2 installed on the floating body 1 are arranged. The method estimates the oscillation of the suspended load 4 in the semi-submerged state in the target water area based on the calculated forces that the floating body 1 and the suspended load 4 receive respectively and the equation of motion for the coupled motion of the floating body 1 and the suspended load 4.SELECTED DRAWING: Figure 1

    【課題】浮体に設けられたクレーンによって吊り下げられた吊荷の半没水状態での動揺を推定できる吊荷の動揺推定方法を提供する。【解決手段】浮体1と浮体1に設置されたクレーン2によって吊り下げた吊荷4とを配置する対象水域の波浪情報を用いて、浮体1が波浪Wから受ける流体力、浮体1が波浪Wに起因して動揺するときに周囲の水塊から受ける力、半没水状態の吊荷4が波浪Wから受ける流体力、および半没水状態の吊荷4が波浪Wに起因して動揺するときに周囲の水塊から受ける力を算出する。そして、その算出した浮体1および吊荷4がそれぞれ受ける力と、浮体1および吊荷4の連成運動についての運動方程式とに基づいて、対象水域における半没水状態の吊荷4の動揺を推定する。【選択図】図1
