Insulation installation method of top anti-roll bearing for b-type independent liquid cargo tank

Abstract

The invention relates to an insulating installation method for a top anti-roll bearing for a B-type independent liquid cargo tank, comprising: 1. installing the top anti-roll bearing; 2. welding a fixed stud; 3. installing a lower anti-roll bearing A perfusion hole and a limit hole are set on the seat panel, and a limit slot is set in the corresponding limit hole of the insulation module in the support area; 4. Insert the limit pin from the limit hole into the limit slot; 5. Seal the open cavity After that, pour the liquid resin into the cavity from the pouring hole until the liquid resin overflows the pouring hole and wait for solidification; 6. Open a through hole on the insulation module in the non-support area, and the through hole is sleeved on the fixed stud and fixed with a nut; 7. Pour resin into the gap between the insulating module in the non-support area and the insulating module in the support area. The insulation installation method of the invention effectively solves the problem of difficulty in insulating installation of the top roll stop support, and the installed support area insulation module and non-support area insulation module can effectively avoid the problem of heat leakage near the top roll stop support .

Description

technical field [0001] The invention relates to the field of ship construction, in particular to an insulating installation method for a top roll stop bearing for a B-type independent liquid cargo tank. Background technique [0002] LNG is a clean energy in the future, and it has a wide range of application prospects as a marine 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 autonomous control when applied to LNG carriers and container ships. The B-type independent tank is filled with liquid LNG at -163°C. In order to prevent external heat from entering the tank and reducing the evaporation of the liquid cargo, an insulating material needs to be installed on the outer surface of the B-type independent tank. [0003] Different from other independent cargo tanks, B-type independent cargo tanks have higher requirements on instal...

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
