Abstract: Disclosed are a cryogenic liquid storage system and a cargo hold of a liquefied natural gas carrier using the same, which are to store and transport a cryogenic liquid such as liquefied natural gas (LNG). The storage system prepared by the present invention comprises a first barrier which is equipped with membranes where creases are formed concavely in order to absorb shrinking and swelling due to thermal deformation when the surface thereof is in contact with a cryogenic liquid; a shock absorbing layer which is installed on the back surface of the first barrier in order to absorb the load applying to the first barrier; and a first insulation layer which is installed for insulation on the back surface of the shock absorbing layer. The cargo hold of an LNG carrier prepared by the present invention comprises vacuum insulation panels which are arranged for insulation on the back surface of the shock absorbing layer; a second barrier which is installed on the back surface of the vacuum insulation panels; and a second insulation layer which is installed for insulation on the back surface of the second barrier. Through the present invention, damage can be effectively prevented by concavely forming the creases of the membranes comprising the first barrier, in turn, by reducing the occurrence of cavitation due to the sloshing of LNG. In addition, the load of shock transmitted to the first insulation layer from the first barrier can be minimized by installing the shock absorbing layer between the first barrier and the first insulation layer. Thus, reliability at ultralow temperatures can be significantly improved by preventing damage to the first and second insulation layers. Furthermore, the first and second insulation layers are formed as the vacuum insulation panel in order to improve the insulation performance; the quality can be guaranteed by lightening the weight thereof and improving the mechanical properties.
