The invention provides a construction method for subsections of a bottom side tank of a liquefied gas ship, which comprises the following steps of: firstly, dividing the subsections of the bottom side tank into three parts, namely an inclined plate middle group, a bottom plate middle group and a bilge curved middle group by taking a bilge linear change position as a boundary; thirdly, the three middle sets are manufactured respectively, and internal related outfitting pieces are pre-buried; and finally, the three parts are assembled in a normal state, butt joints are welded, bulk parts are installed, and internal outfitting parts are installed in place. According to the method, the construction height can be reduced, the scaffold erection workload is reduced, repeated scaffold erection is effectively avoided, and the labor cost is effectively saved; in addition, the installation precision is remarkably improved, and reworking caused by poor assembly precision is reduced; the division method of the bottom side tank sections is optimized, so that the construction difficulty is reduced; and finally, the three parts of the middle group are constructed at the same time, and parts assembled and welded in the large group stage in the traditional construction mode are moved forwards to the middle group stage, so that the construction time of the large group is greatly shortened.
本发明提供一种液化气船底边舱分段的建造方法,首先,以舭部线型变化位置为界,将底边舱分段划分为斜板中组、底板中组和舭部曲型中组三部分;接着,分别制作上述三个中组,并预埋内部的相关舾装件;最后,将三部分中组正态合拢,焊接对接缝,安装散装件并将内部舾装件安装到位。本发明能够降低施工高度,减少脚手架搭设工作量,且有效避免脚手架重复搭设,有效节省人力成本;另外,安装精度显著提高,减少因装配精度不良导致的返工;优化了底边舱分段的划分方法,从而降低施工难度;最后,三部分中组同时进行建造,且将传统建造方式中的大组阶段装配和焊接的部件前移至中组阶段,大大缩短了大组的建造时间。
