Supporting structure between liquefied gas ship and dual-lug type liquid tanks

Abstract

The invention provides a supporting structure between a liquefied gas ship and dual-lug type liquid tanks. The supporting structure comprises the two liquid tanks arranged side by side in the length direction of a ship body, the bottoms of the two liquid tanks are provided with support seats, and parts, located between the two liquid tanks, of the support seats are inwards concave in the length direction of the ship body to form grooves; an anti-transverse rolling support arranged at the intermediate position of the inner bottom of the ship body is further included, the anti-transverse rolling support forms slopes from top to bottom towards the two broadsides of the ship body, the bottoms of the slopes extend to the two broadsides to form horizontal vertical supports, the slopes are provided with first limiting frames, the top surfaces of the vertical supports are provided with second limiting frames, the positions, corresponding to the first limiting frames, of the grooves are provided with first laminated wood placed in the first limiting frames, and the positions, corresponding to the second limiting frames, of the bottoms of the support seats are provided with second laminated wood placed in the second limiting frames. The supporting structure is convenient to install, the anti-transverse rolling support and the vertical supports can be synchronously constructed and installed, the work efficiency is improved, and the workload of workers is reduced.

Description

technical field [0001] The invention relates to the field of liquefied gas ships, in particular to a support structure between a liquefied gas ship and a double ear tank. Background technique [0002] Liquid tanks are used to load liquefied gas at low temperature on liquefied gas ships. The liquid tanks do not constitute a part of the hull structure, are independent of the hull structure, and can bear their own weight and the static and dynamic loads of the internal liquid. [0003] The hull structure needs to bear the weight of the tank and its cargo. At the same time, it is also necessary to consider the movement of the ship in waves and the dynamic load caused by the movement of the cargo inside the tank. It is necessary to have an appropriate form of support structure between the hull and the tank. Transfer various loads. The tank is connected to the hull structure through a series of supporting systems, and its supporting system bears the key role of transferring loads...

AI Technical Summary

Problems solved by technology

[0005] For the anti-rolling device that restricts the lateral movement of the tank, the traditional design is generally stepped, and the contact surface is in the form of laminated wood and epoxy, but it is in contact with the vertical surface and is separated from the supporting device that bears the vertical load. It does not play a supporting role, the overall construction is cumbersome, and the workload is large
