The invention discloses a method for launching a ship by using a floating dock. The method comprises the following steps of 1, ship moving: moving the ship to the floating dock, 2, pier falling, after the ship moves in place, falling slowly, 3, anchoring, moving the floating dock to the anchoring ground through a tug, and anchoring and positioning, 4, sinking, opening a water inlet valve of a ballast tank of the floating dock, enabling water to flow into the ballast tank under the action of gravity, and enabling the ship to sink, 5, undocking: slowly dragging the ship out of the floating dock from the tail part by adopting the cooperation of a winch and a tug, and 6, conducting berthing, specifically, moving the ship to the corresponding berth through tugs, tying the cable, and conducting berthing. The method has the beneficial effects that only the draft height of the head and the tail needs to be adjusted when the ship sinks, and extra time and cost are not increased; the whole launching time of the ship is shortened, the requirement for the load of the floating dock is reduced, the requirement for corollary equipment is reduced, and the cost is reduced.

    本发明公开了一种利用浮船坞进行船舶下水的方法,该方法包括以下步骤:步骤一、移船:将船舶移动到浮船坞上;步骤二、落墩:当船舶移动到位后,缓慢落位;步骤三、抛锚:采用拖轮将浮船坞移动到锚地,抛锚定位;步骤四、下沉:打开浮船坞压载舱的进水阀,在重力作用下自流进压载舱,使船舶下沉;步骤五、出坞:采用绞车和拖轮配合将船舶从尾部缓慢拖出浮船坞;步骤六、靠泊:采用拖轮将将船舶移动到相应的泊位,并系好缆,靠泊。本发明的有益效果是,只需要在船舶下沉的时候注意调整首尾的吃水高度,不增加额外的时间和费用;缩短船舶下水整体的时间,降低对浮船坞载荷的要求,减少了配套设备的需求,降低了成本。
