Docking method of ship structural body

The invention provides a method for undocking a ship structural body, the height of the ship structural body is lower than the height of a dock, and the method comprises the following specific steps: fixing a cable protection tool; a belt cable is arranged in a penetrating mode, and the belt cable penetrates through the belt cable protection tool; the belt cable penetrates through the protection tool and then is connected with a winch. According to the undocking method of the ship structural body, the undocking or floating stability of the whole ship structural body can be guaranteed, the whole ship structural body is prevented from deviating from a dragging rail when undocked, the belt cable protection tool is arranged in the undocking method, replacement of the belt cable can be reduced while the belt cable is protected, and the shipbuilding cost is reduced. 本发明提供一种船舶结构体的出坞方法，船舶结构体的高度第低于船坞高度，具体的步骤为：固定带缆保护工装；穿设带缆，所述带缆穿过所述带缆保护工装；所述带缆穿过所述保护工装后连接卷扬机；本发明的提供的船舶结构体的出坞方法可以保证整船结构体出坞或起浮的稳定性，防止整船结构出坞时偏离拖行轨道，在本方法中设置了带缆
