The invention discloses a method for constructing a gas dome barrel of an LNG ship in an outer field. The method comprises the steps that a carrying lifting ring is installed on a dome deck; the domedeck is inversely placed on a jig frame by utilizing the carrying lifting ring, and an inner deck is normally placed on the jig frame; a framework installation line and a barrel inspection line are drawn on the dome deck according to a construction drawing; a framework and the barrel are welded and fixed to the dome deck according to the framework installation line and the barrel inspection line;after the framework, the barrel and the dome deck are fixed into a whole, the whole is turned over to be aligned and folded with the inner deck; and the barrel and the inner deck are welded and fixed.According to the method for constructing the gas dome barrel of the LNG ship in outer field, the gas dome barrel is independently manufactured in the outer field, so that the problem that the storageperiod of the gas dome barrel lags behind due to the fact that a traditional gas dome barrel is folded in the inner field and sections is effectively solved, and the constructing time of the gas domebarrel is greatly shortened.

    本发明公开了一种LNG船气穹筒体外场建造方法,包括以下步骤:在穹顶甲板上安装搭载吊环;利用搭载吊环将穹顶甲板反态放置到胎架上,将内甲板正态放置在胎架上;按照施工图纸,在穹顶甲板上划制构架安装线和筒体检验线;按照构架安装线和筒体检验线,将构架和筒体焊接固定在穹顶甲板上;构架和筒体与穹顶甲板固定为一体后将该整体翻身与内甲板上对准合拢;将筒体与内甲板焊接固定。本发明通过在外场单独制作气穹筒体,有效地解决了传统气穹筒体在内场与分段合拢造成气穹筒体纳期滞后的的问题,大大缩短了气穹筒体的建造时间。
