The invention discloses a block strength test and insulation installation method for a gas transport ship. The method comprises the steps that a block of a cargo hold ring section is divided into a left broadside and double-bottom-layer L-shaped block and a right broadside and double-bottom-layer L-shaped block and a deck block; the cargo hold ring section is provided with a left ballast tank and a right ballast tank, and the bottoms of the two ballast tanks are separated through a pipe tunnel tank; the broadside and double-bottom-layer L-shaped block structure is placed in a normal state after being completed, and a bracket and a direction stabilizing frame are arranged on an outer plate of the broadside and double-bottom-layer L-shaped block structure; a vent pipe is arranged at the highest point of the top of the broadside-added double-bottom-layer L-shaped block, water injection is started after preparation work is finished, and a strength test is completed; the broadside and double-bottom-layer L-shaped block is placed in a wind and rain shed; and heat preservation layers are installed in a double-layer bottom area, a transverse bulkhead area and an inner shell area of the broadside added double-bottom-layer L-shaped block. And the dock period can be greatly shortened.
本发明公开了一种气体运输船的总段强度试验及绝缘安装方法,包括:将货舱环段的总段划分为左右两个舷侧加双底层L型总段和甲板总段;货舱环段有左右两个压载舱,两个压载舱之间在底部通过管弄舱分隔开;舷侧加双底层L型总段结构完工后正态放置,并在其外板处设置牛腿及稳向架;在舷侧加双底层L型总段顶部最高点设置透气管,准备工作结束后开始注水,完成强度试验;将舷侧加双底层L型总段放置在风雨棚内;在舷侧加双底层L型总段的双层底区域、横舱壁区域以及内壳区域安装保温层。能够大幅缩短船坞周期。
