The invention relates to an LNG (Liquefied Natural Gas) ship bottom section dividing and assembling method which comprises the following steps: step 1, transversely dividing the bottom of an LNG ship into three sections, namely a left section, a middle section and a right section; secondly, the left section and the right section are longitudinally assembled, and scaffolds are erected on inner bottom plates of the left section and the right section; and thirdly, the middle sections are longitudinally assembled, and the blocks are hoisted into a dock after being integrally pre-assembled. According to the segmented dividing and total assembling method for the bottom of the LNG ship, the load of a gantry crane can be effectively reduced, the integrity of the total segment is improved, and therefore the building period of a dock is shortened, and the building cost of the dock is reduced.
本发明涉及一种LNG船底部的分段划分及总组方法,包括以下步骤:步骤一,将LNG船底部横向划分为三段,三段分别为左分段、中间分段和右分段;步骤二,将所述左、右分段分别进行纵向总组,在左、右分段内底板上搭设脚手架;步骤三,将所述中间分段进行纵向总组,完成总段完整性预装后将总段吊装进坞。本发明的一种LNG船底部的分段划分及总组方法,能有效降低龙门吊负荷、提高总段完整性,从而缩短船坞建造周期,降低船坞建造成本。
