Insulation installation method for top rolling stopping support of B-type independent liquid cargo tank

Abstract

The invention relates to an insulation installation method for a top rolling-stopping support of a B-type independent liquid cargo tank. The insulation installation method comprises the following steps: 1, mounting the top rolling-stopping support; 2, welding a fixing stud; 3, forming a pouring hole and a limiting hole in a lower rolling stopping support panel, and forming a limiting groove is formed in the portion, corresponding to the limiting hole, of the insulation module in the support area; 4, inserting a limiting pin into the limiting groove from the limiting hole; 5, after the opened cavity is sealed, pouring liquid resin into the cavity from the pouring hole until the liquid resin overflows out of the pouring hole, and solidification is waited; 6, through holes are formed in the insulation module in the non-support area, the through holes are arranged on the fixing studs in a sleeving mode, and the fixing studs are fixed through nuts; and 7, pouring resin into a gap between the non-support area insulation module and the support area insulation module. According to the insulation installation method, the problem that the insulation installation difficulty of the top rolling stopping support is large is effectively solved, and the installed support area insulation module and the installed non-support area insulation module can effectively avoid the problem of heat leakage nearby the top rolling stopping support.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an insulation installation method for a top anti-rolling support used for a B-type independent liquid cargo tank. Background technique [0002] LNG is a clean energy source in the future, and has broad application prospects as a ship power fuel. As the type of liquid cargo containment system allowed by the IGC rules, the B-type tank has the advantages of flexible design, good sloshing performance, short construction period and independent controllability when applied to LNG carriers and container ships. Type B independent liquid cargo tank contains liquid LNG at -163°C. In order to prevent external heat from entering the liquid cargo tank and reduce the evaporation of liquid cargo, insulating materials need to be installed on the outer surface of the type B independent tank. [0003] Different from other independent liquid cargo tanks, the installation method and precision requiremen...

AI Technical Summary

Problems solved by technology

[0004] The anti-roll support on the top of the Type B independent liquid cargo tank is installed in the middle of the top surface of the liquid cargo tank to limit the lateral displacement of the Type B independent liquid cargo tank. Due to the large lateral acceleration load of the ship during the normal operation of the ship, the The anti-rolling support structure bears a lot of force. In order to ensure its structural strength, the design of the cross plate is adopted in the design of the support. Therefore, it is more difficult to install the insulating blocks near it, and it is also easy to cause damage to the hull structure due to omissions. big security risk
