Abstract

The liquefied natural gas cargo tank cavity panel includes a first cavity wall panel and a second cavity wall panel laminated for a secondary cavity wall of an liquefied natural gas cargo tank, each cavity wall panel comprising: a first metal layer; a second metal layer; and glass A fiber layer is arranged between the first metal layer and the second metal layer and integrated by bonding.

Description

technical field [0001] The present invention relates to a cavity wall structure of a liquefied natural gas cargo tank of a liquefied natural gas carrier or a floating offshore structure producing and storing liquefied natural gas, in particular to a cavity wall structure of a liquefied natural gas cargo tank and a cavity used for the cavity wall structure Wall panels. Background technique [0002] Generally, liquefied natural gas (LNG) refers to a colorless and transparent ultra-low temperature liquid that is cooled to about -163°C to reduce its volume by 1 / 600 of natural gas mainly composed of methane. [0003] A LNG carrier that transports the above-mentioned LNG or a floating offshore structure that produces and stores LNG has a cargo tank capable of storing and storing LNG liquefied in an ultra-low temperature state. In the LNG cargo tank described above, a membrane is used as the primary chamber wall and a triplex is used as the secondary chamber wall. Among them, the...
