Installing structure of liquid tank of large liquefied gas carrier and installation locating method of liquid tank

Abstract

The invention provides an installing structure of a liquid tank of a large liquefied gas carrier and an installation locating method of the liquid tank. According to the installing structure of the liquid tank of the large liquefied gas carrier, a liquid tank cabin of the large liquefied gas carrier is mainly provided with a bottom perpendicular supporting base, a bottom transverse-shake preventing support, a top transverse-shake preventing support and a bottom longitudinal-shake preventing support, wherein the bottom perpendicular supporting base is used for supporting a whole liquid tank, the bottom transverse-shake preventing support and the top transverse-shake preventing support are used for preventing the liquid tank from transversely shaking relative to a hull, and the bottom longitudinal-shake preventing support is used for preventing the liquid tank from longitudinally shaking relative to the hull. In the actual working process of installing the liquid tank in the liquid tank cabin, according to the installation locating method of the liquid tank, the data collection step, the three-dimensional simulation step, the epoxy resin thickness calculation step, the locating datum line assignment step, the supporting positioning step and the like are carried out in sequence, and finally the liquid tank is installed in the liquid tank cabin. By the adoption of the installation locating method of the liquid tank, installation locating work of the liquid tank can be rapidly and accurately accomplished, the utilization rate of tools is high, the using time of a crane is short, and the construction cost of an enterprise is greatly reduced.

Description

Technical field [0001] The invention relates to a method for installing a liquid tank of a liquefied gas ship, in particular to a method for installing and positioning a liquid tank through a surveying and mapping device. Background technique [0002] At present, the domestic shipbuilding industry is developing in the direction of products with high added value, high technology content, and high construction difficulty. Large-scale liquefied gas ships are also one of them. [0003] Liquefied gas ships are liquid cargo ships that specialize in transporting liquefied gas. Generally, they can be divided into liquefied natural gas ships and liquefied petroleum gas ships. The key technology of the liquefied gas ship is concentrated in the liquid tank area, and the hoisting and positioning of the liquid tank is one of the key technologies in the construction of this type of ship. Whether the hoisting can be effectively controlled directly determines the success of the ship's construction...

AI Technical Summary

Problems solved by technology

At present, small-scale liquefied gas ships have been successfully built in China, but their tanks are small tanks with small volumes, and their installation and positioning methods are quite different from those of large-scale liquefied gas ships. The installation and positioning method of the liquid tank of the ship is still in the exploratory stage
