Abstract: An adiabatic structure of a liquefied gas vessel is provided to improve adiabatic performance between an inner tank and an outer tank of a reservoir by reducing heat transmission through a support part supporting the inner tank and the outer tank. An adiabatic structure of a liquefied gas vessel comprises an inner tank(3) and an outer tank(1). The inner tank is installed inside the outer tank. A support arm(5) protruded from the inner tank is inserted into a support plate(7) installed inside the outer tank. The adiabatic material(9) is interposed in a coupling part between the support arm and the support plate. The adiabatic material blocks direct metallic contact between the support plate and the support arm. The outer circumference of the adiabatic material is coupled with a coupling hole formed on the support plate. An inserting hole in which the support arm is inserted is formed on the inner circumference of the adiabatic material.

A prefabricated liquid gas vessel comprises a reservoir(10), a connection part(12), a port assembly(14), a partitioning part(16), a charge guiding part(18) and a support(20). The reservoir comprises an inner tank(10a) and an outer tank(10b). The connection part passes through the reservoir and connects the inner tank to outside. The port assembly is detachably coupled with the connection part and has a plurality of pipes. The partitioning part divides the internal space of the inner tank into a storage space part(S) and a decrement space part(U). The port assembly is installed in the decrement space part through the connection part. The charge guiding part induces the liquefied fuel charged through the port assembly to the storage space part.
