Abstract

The invention provides a repair method of an insulating layer of a rhombic independent cargo tank. Repair of the insulating layer mainly comprises the steps of checking the insulating layer, determining first to-be-repaired areas, cleaning and repairing the first to-be-repaired areas, laying a protection layer, determining second to-be-repaired areas and repairing the second to-be-repaired areas. According to different defect types of the insulating layer, different repair methods are adopted, it is ensured that the insulating layer outside the cargo tank is continuous and reliable, and effective and stable support is provided for insulation of the whole cargo tank. The repair method further has the beneficial effects of being good in repair effect and high in repair quality.

Description

technical field [0001] The invention relates to a liquefied gas ship, in particular to a method for repairing the insulating layer of a diamond-shaped independent liquid cargo tank. Background technique [0002] The design temperature of a large fully cooled liquefied gas carrier (VLGC) is -50 degrees. The gas temperature in the diamond-shaped independent liquid tank is low, and an effective insulation system must be used to achieve the purpose of heat preservation and preventing temperature diffusion. The insulation protection of the diamond-shaped independent liquid tank is mainly composed of two parts: the insulation layer (referred to as the insulation layer) and the surface protection coating (referred to as the protective layer). The insulating layer is mainly for heat insulation, while the protective coating is responsible for protecting the insulating layer from damage, which has good mechanical protection and waterproof effect. The laying of these two parts must h...
