Abstract

A membrane welding device guide system according to the present invention comprises: an anchor strip arranged on an insulation wall which configures an insulation system of a liquefied gas storage tank; a stud integrally formed with the anchor strip, the center of the stud deviating from a welding line of the anchor strip; and a guide rail which is coupled to the stud to form a path of an automatic membrane welding device for welding a membrane to be stacked on the insulation wall. Therefore, the present invention allows membrane welding to be easily performed and allows a membrane welding device to be stably guided.

Description

technical field [0001] The invention relates to a membrane assembly for facilitating the welding of membranes of a membrane storage tank, and a membrane welding device guidance system comprising said membrane assembly. Background technique [0002] Natural gas is a fossil fuel containing methane as a main component and a small amount of ethane, propane, etc., and is attracting attention as a low-pollution energy source in various technical fields . [0003] Natural gas is transported in gaseous form via onshore or offshore gas pipelines, or in liquid form via liquefied natural gas (LNG) carriers to distant destinations. LNG is obtained by cooling natural gas to a cryogenic temperature (about -163°C or below), and its volume is about 1 / 600 of gaseous natural gas. Therefore, LNG is suitable for long-distance sea transportation. [0004] The LNG carrier is provided with an LNG storage tank (also referred to as an "LNG cargo tank") capable of storing LNG obtained by cooling a...
