Installation method of gas chamber enclosure bulkhead and liquid tank on liquefied gas carrier

Abstract

The invention provides an installation method of an air chamber enclosure bulkhead and a liquid tank on a liquefied gas carrier, and the installation method comprises the following steps: before hoisting, marking a first datum line group on the liquid tank, and determining air chamber positioning information on the liquid tank based on the first datum line group; and marking a second reference line group on the full-width deck. And air chamber holes are formed in the full-width deck according to the air chamber positioning information and the second datum line set. And after the height of the enclosure bulkhead is determined, allowance cutting is conducted on the enclosure bulkhead according to the height of the enclosure bulkhead. And the cut enclosure bulkhead is installed at the air chamber hole of the full-width deck. And the liquid tank and the full-width deck are hoisted according to the first datum line set and the second datum line set, and the enclosure bulkhead is arranged outside the air chamber in a covering mode. The cutting work of the enclosure bulkhead is carried out before hoisting of the full-width deck, so that the enclosure bulkhead can be prevented from being cut on the outer side of the liquid tank, an insulating material on the outer side of the liquid tank is prevented from burning, the production efficiency of the liquefied gas carrier is improved, and meanwhile, the safety in the production process is guaranteed.

Description

technical field [0001] The present application relates to the technical field of shipbuilding, in particular to a method for installing an air chamber enclosure and a liquid tank on a liquefied gas ship. Background technique [0002] The air chamber is a part of the liquid tank on the liquefied gas ship, which plays the role of sealing the liquid tank. When loading liquefied gas on a liquefied gas ship, it is necessary to connect the pressure pump through the air chamber, and load the liquefied gas into the liquid tank through the pressure pump; at the same time, the liquefied gas is changed from gaseous state to liquid state through ultra-low temperature condensation. However, the liquefied gas at the location of the gas chamber remains in a gaseous state, and the gaseous liquefied gas at this place acts to reduce the internal pressure contraction. [0003] Such as figure 2 As shown, a wall is set outside the gas chamber, the bottom of the wall is connected with the full-...

AI Technical Summary

Problems solved by technology

Because the material of the insulator is flammable, there is a very big safety hazard when trimming

Construction personnel will spend a lot of time and energy to prevent the insulation material from burning, which will increase the difficulty of construction and the construction period
