The invention discloses a method for positioning and installing a pump tower of an LNG ship. The method specifically comprises the following steps that a liquid dome section and a deck section are manufactured; marking a first sample punching mark on the inner deck of the liquid dome subsection, and marking a second sample punching mark on the inner deck of the deck subsection; carrying the deck subsection on the cargo hold, and reversely connecting the second sample punching mark on the deck subsection to a ship body inner bottom plate of the cargo hold to determine the mounting position of the pump tower base; a pump tower base is installed, and the pump tower is hoisted on the pump tower base; hoisting the liquid dome subsection into the hole of the deck subsection, so that the first sample punching mark on the liquid dome subsection is aligned with the axis of the pump tower; and the liquid dome subsection, the pump tower, the cargo hold and the deck subsection are welded into a whole. The positioning and mounting precision of the pump tower is improved, the construction progress of a ship is shortened, and the construction period of the ship is shortened.

    本发明公开了一种LNG船泵塔定位安装方法,具体包括以下步骤:制造液穹分段和甲板分段;在液穹分段的内甲板上标注第一样冲标记,在甲板分段的内甲板上标注第二样冲标记;将甲板分段搭载在货舱上,将甲板分段上的第二样冲标记反驳至货舱的船体内底板上以确定泵塔基座的安装位置;安装泵塔基座,将泵塔吊装在泵塔基座上;将液穹分段吊装至甲板分段的孔洞内,使液穹分段上的第一样冲标记与泵塔轴心相对齐;将液穹分段与泵塔、货舱和甲板分段焊接为一体。本发明不仅提高了泵塔的定位安装精度,也缩短了船舶的建造进度,缩短了船舶的建造周期。
