Abstract

The invention discloses a method for installing insulation modules on an LNG ship liquid cargo tank. The method comprises the following steps that S1, corner insulation modules and plane insulation modules are manufactured according to the shape of an angle area of the liquid cargo tank; S2, installation reference lines are drawn along the transverse direction and the longitudinal direction of theliquid cargo tank; S3, corner insulation modules at the angle area with downward openings are installed; S4, plane insulation modules at the upper half portion of the liquid cargo tank are installed;S5, corner insulation modules at the angle area with downward openings are installed; S6, plane insulation modules at the lower half portion of the liquid cargo tank are installed; and S7, glass woolis installed between the adjacent corner insulation modules, between the adjacent corner insulation module and the plane insulation module, and between the adjacent plane insulation modules. According to the method, the installation precision is high, the distances between the corner insulation modules and the installation reference lines and between the plane insulation modules and the installation reference lines can be rapidly and accurately measured through the specially-made adjusting tool, and the installation efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of containment systems for cargo tanks of LNG ships, and in particular relates to an installation method of an insulation module of liquid cargo tanks of LNG ships. Background technique [0002] The Mark 3 containment system is currently the mainstream LNG ship containment system. The Mark 3 containment system is insulated by insulation modules, and the insulation modules are connected to the hull through resin. The number of insulation modules is large, the weight is high, the installation accuracy is high, and the installation cycle is long. The installation cycle of the insulation module directly affects the installation cycle of the entire maintenance system, especially the single weight of the corner insulation module exceeds 300 kg, and the insulation cannot be damaged during the installation process. The resin at the bottom of the module can be installed with an accuracy of 1 mm, and the installation of the cor...
