The invention discloses a positioning method for over-water air-spaced butt joint of a half ship and a block. The positioning method specifically comprises the following steps that determining the linear deviation delta L of a ship body structure at the position where a marking point on the half ship is located; carrying out floating and lying of the half ship to a second dock, and calculating thefalling deviation angle a of the half ship according to the distance L between the marking point on the half ship and a second reference line on the side edge of the second dock and the linear deviation delta L of the ship body structure at the position where the marking point is located; carrying out positioning and lying on a fuel cabin block according to the falling deviation angle a of the half ship; and embedding embedding sections in an embedding area between the half ship and the fuel cabin block. The method is easy to operate and convenient to implement, the fuel cabin block is positioned in place at a time after floating, secondary adjustment and positioning do not need to be conducted on the position of the fuel cabin block, the time for conducting secondary adjustment operationthrough a three-dimensional jacking trolley in a traditional method is shortened, the carrying period of a dock is shortened, and the production cost of an enterprise is saved.

    本发明公开了一种半船与总段水上隔空对接的定位方法,具体包括以下步骤:确定半船上标记点所在位置处船体结构的线型偏差ΔL;半船起浮落墩到第二船坞,根据半船上标记点到第二船坞侧边上的第二参考线的距离L和标记点所在位置处船体结构的线型偏差ΔL计算半船的落位偏差角a;根据半船的落位偏差角a对燃料舱总段进行定位落墩;将嵌补分段嵌装在半船与燃料舱总段之间的嵌补区域内。本发明的方法操作简单、实施方便,燃料舱总段漂浮后一次定位到位,不需要对其位置进行二次调整定位,减少了传统方法中使用三维顶升小车进行二次调整作业的时间,不仅缩短了船坞的搭载周期,也节约了企业的生产成本。
