Top rolling stopping support structure for B-type independent liquid cargo tank

Abstract

The invention relates to a top rolling stopping support structure for a B-type independent liquid cargo tank, which structurally comprises an upper ship body rolling stopping support, laminated wood and a lower liquid cargo tank rolling stopping support, the lower liquid cargo tank rolling stopping support is mounted at the top of the B-type independent liquid cargo tank, and the laminated wood is fixed on two sides, close to the upper end, of the lower liquid cargo tank rolling stopping support. The upper ship body rolling stopping supports are arranged on the two sides of the laminated wood on the two sides of the lower liquid cargo tank rolling stopping supports in a clamped mode. According to the top rolling stopping support for the B-type independent liquid cargo tank, the transverse displacement of the B-type independent liquid cargo tank is limited, meanwhile, the structural rigidity of the rolling stopping support due to the large transverse acceleration load of a ship body can be reduced, and the structural strength of the rolling stopping support is improved through the design of the cross plate.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a top anti-roll support structure 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. Especially as the LNG fuel tank of container ships, compared with membrane tanks and C-type tanks, the construction and installation process of B-type tanks is relatively simple. Due to the high utilization rate of tank capacity, more liquid LNG can be loaded , so as to provide sufficient LNG power fuel for container ships during actual ship operation. [0003] Type B independent liquid cargo tank contains liquid LNG a...

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, and the design and installation rationality of the support seat and insulation module are very important. If any omission occurs, the structure of the cargo tank is damaged and LNG leaks, which will pose a great hidden danger to the safety of the ship.
