The invention relates to a sawtooth-shaped damping device for a cylindrical ship body. The sawtooth-shaped damping device comprises the cylindrical ship body and three damping box bodies. The three damping box bodies are the same in shape and are arranged at the bottom of the side face of the cylindrical ship body at equal intervals. The damping box body comprises a rotary box body and a plurality of tooth-shaped box bodies. The rotary box body and the tooth-shaped box body are both of a shell plate structure and are independent of each other. The tooth-shaped box body is of a closed shell plate structure and is not communicated with seawater, the interior of the tooth-shaped box body is a void, and ballast water is not loaded. The tooth-shaped box bodies are the same in shape, the horizontal sections of the tooth-shaped box bodies are arc-edge trapezoids or arc-edge triangles, the vertical height of the tooth-shaped box bodies is equal to that of the outer side of the rotary box body, and the tooth-shaped box bodies are conveniently welded to the The tooth-shaped box body and the rotary box body are independent from each other, the welding strength between the tooth-shaped box body and the rotary box body is lower than the welding strength between the rotary box body and the cylindrical ship body, and damage or falling of one or more tooth-shaped box bodies cannot cause large influence on stability, safety and the like of the cylindrical FPSO.

    本发明涉及一种用于筒型船体的锯齿形阻尼装置,包括筒型船体和三个阻尼箱体。三个阻尼箱体形状相同,等间距布置于所述筒型船体侧面底部。阻尼箱体包括回转箱体和多个齿形箱体。回转箱体和齿形箱体均为壳板结构,且彼此独立。齿形箱体为封闭壳板结构,不与海水连通,内部为空舱,不装载压载水。齿形箱体形状相同,水平截面为弧边梯形或弧边三角形,垂向高度与回转箱体外侧垂向高度相同,便于焊接于回转箱体外侧。齿形箱体与回转箱体彼此独立,且齿形箱体与回转箱体之间的焊接强度低于回转箱体与筒型船体间的焊接强度,单个或多个齿形箱体的破损或脱落不会对圆筒型FPSO的稳性、安全等造成较大的影响。
