The invention discloses a gas transport ship block strength test and insulation installation method. The method comprises the steps that a block of a cargo hold ring section is divided into a left broadside block, a right broadside block, a bottom double-bottom-layer 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 block structure is placed in a normal state after being constructed, and an opening in a bottom longitudinal girder of the broadside block is blocked; the left side block and the right side block are placed face to face, and the left side block and the right side block are placed on a strength test service rack for a first strength test; after the first strength test is completed, a heat preservation layer is installed on the lateral state broadside block; opening holes in bottom longitudinal girders of the double-bottom-layer block are blocked; after the preparation work is finished, water injection is started, and a second strength test is completed; and a thermal insulation layer is mounted on the double-bottom-layer block. And the dock period can be greatly shortened.
本发明公开了一种气体运输船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总段、底部的双底层总段和甲板总段;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;舷侧总段结构完工后正态放置,将舷侧总段的底纵桁上的开孔进行封堵;将左右舷侧总段面对面进行搁置,并放置于强度试验服务架上进行第一强度试验;第一强度试验完成后,在侧态舷侧总段上安装保温层;将双底层总段的底纵桁上的开孔进行封堵;准备工作结束后开始注水,并完成第二强度试验;在双底层总段上安装保温层。能够大幅缩短船坞周期。
