Abstract

PURPOSE:To improve the operability of a heat-proof method by arranging heat insulating unit panels in which a blowing agent is injected on the outer surface of a tank with a gap therebetween, and filling the gap with glass wool. CONSTITUTION:A metallic wrapping material 3 is first inserted in a blowing frame, and a blowing agent is injected to make a unit panel 2. The unit panels are arranged on the outer surface of a gas tank 1 with a gap therebetween, and the gap between the adjacent unit panels is filled with glass wool 5. Lastly, pointing tapes 6 are sticked to the unit panels in such a manner as to cover the glass wool 5 and heat insulating material buried in the unit panels. Thus, the processes can be conducted to manufacture unit panels in a factory to improve the operability of heat-proof execution.

Furthermore, since the above working space is required, there is also the problem that the space between the tasik and the hull cannot be reduced. Also, since it was foamed on-site, it was not possible to confirm the quality of the insulation material O2. Furthermore, in the event that low-temperature liquefied gas leaks from the low-temperature liquefied gas tank (c), a leak shield (not shown) must be installed on the outer surface of the insulation material IJ4 in order to guide it to the partial secondary barrier. There were also problems.
