PURPOSE: An LNG tank carrier is provided to minimize time and costs used for manufacturing a carrier for a tank since a structure for supporting an upper container box is used in a container ship to support a tank. CONSTITUTION: An LNG tank carrier(700) comprises a cargo hold(720), a first upper support(730), a second upper support(740), and a lower support(750). The cargo hold does not include an insulation facility. The first and second support supports divide the upper part of the cargo hold into a number of openings. A tank is vertically inserted into each opening. The lower support is installed on the lower part of the cargo hold and supports the lower part of the tank inserted into the opening. The tank consists of an inner shell and an outer shell.
