CARGO TANK FOR LIQUEFIED GAS

摘要

PURPOSE: A double barrier tank for carrying and storing liquid gas is provided to improve the intensity of the inside aggregate and outer panel and to make stresses distribution of the outer panel even. CONSTITUTION: A double barrier tank for carrying and storing liquid gas comprises an outer panel, an inside aggregate, a heat insulator(15), a reinforced beam(12), and multiple membrane sheets(17). The outer panel comprises multiple traverse direction crease plate. The inside aggregate is attached to the point part of the creases and is located in the inner side of the outer panel. The heat insulator surrounds the outer panel in order to prevent the heat conduction between the inside and outside of the outer panel. The membrane sheet is attached to the reinforced beam and the neighboring inside aggregate.
