Abstract
In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.
Claims8
A membrane type insulation system for cryogenic liquefied gas carrier cargo tank and liquefied gas fuel container, the membrane type insulation system comprising:
- a primary insulation layer disposed at a liquefied gas side;
- a secondary insulation layer disposed on an inner wall of a hull, wherein the secondary insulation layer comprises a plurality of panels separately stacked in a multilayer structure in a thickness direction of the secondary insulation layer such that upper and lower panels are staggered;
- and
- a panel securing unit configured to secure an upper panel of the plurality of panels to the inner wall of the hull via a lower panel of the plurality of panels that is provided between the upper panel and the inner wall of the hull.
