Abstract

The invention provides an installation process of a liquid cargo tank broadside temporary insulation module. The liquid cargo tank broadside temporary insulation module is installed at the end part ofa conventional insulation module, and the end part of the conventional insulation module is of a big-end-down stepped structure. The installation process comprises the following steps: 1, installinga temporary sub-layer insulation module along the periphery of a broadside opening; 2, installing a secondary-layer apron board along the periphery of the broadside opening, wherein the upper end surface of the secondary-layer apron board is as high as the conventional secondary-layer insulation module; 3, mounting temporary main layer insulation modules along the periphery of the broadside opening; and 4, mounting a main-layer apron board along the periphery of the broadside opening, wherein the upper end surface of the main-layer apron board is as high as the conventional main-layer insulation module. During installation, smeared resin and glue do not make direct contact with the temporary secondary-layer insulation module and the temporary main-layer insulation module and are mixed withtransparent adhesive tape or kraft paper, so that disassembly is convenient, damage to the temporary secondary-layer insulation module and the temporary main-layer insulation module is avoided, and the temporary secondary-layer insulation module and the temporary main-layer insulation module can be repeatedly used.

Description

Technical field[0001]The invention relates to the technical field of ship construction, in particular to an installation process of a temporary insulation module of a liquid cargo tank.Background technique[0002]In the construction of the cargo tank of the Mark 3 LNG ship, insulating materials such as insulation modules are used as the temperature insulation material for the liquefied natural gas to ensure that the natural gas in the cargo tank is maintained at a liquid state below -163°C and to prevent the low-temperature embrittlement caused by the direct contact of the liquefied natural gas with the hull. The cargo tank of the Mark 3 LNG ship adopts the secondary insulation module and the primary insulation module to achieve the temperature insulation effect, and the FSB adhesion of the secondary layer and the installation of the corrugated board of the main layer achieve airtight effect.[0003]The side opening is the main import and export of scaffolds, elevators, materials, and e...
