Abstract

The invention relates to a liquefied natural gas carrier independent cargo space insulation layer system and a construction method thereof. The liquefied natural gas carrier independent cargo space insulation layer system comprises a prefabricated insulation plate module, wherein the prefabricated insulation plate module comprises anti-splashing screen plates and a polyurethane foam insulation plate; the anti-splashing screen plates which are installed continuously and elastic sub-screen wall film seal connectors which are arranged between above a gap between two adjacent anti-splashing screen plates in a bonding manner and used for sealing the gap form a sub-screen wall layer; and the liquefied natural gas carrier independent cargo space insulation layer system comprises a protection layer, a filling insulation material, a fixed bolt, a nut and a seal washer. By adopting the technical scheme, the insulation problem of an IMO B-type cargo space can be solved.

Description

technical field [0001] The invention relates to the technical field of new liquefied natural gas ships, in particular to a construction method of a prefabricated heat insulation panel module, a heat insulation layer system of an independent liquid cargo tank of a liquefied natural gas ship and a construction method thereof. Background technique [0002] Liquefied natural gas refers to a colorless, transparent low-temperature liquid that cools natural gas whose main component is methane to about -163°C and compresses it to 1 / 600 of its gas volume. It is an important clean energy. The liquefied natural gas ship is the main means of transportation of liquefied natural gas at sea. It is a high-tech, high-difficulty and high-value-added ship, known as the "crown jewel" of the world's shipbuilding. [0003] During the voyage of LNG ships, the temperature difference between the liquid cargo and the external environment is as high as nearly 200°C, so a large amount of heat will flo...
