The present invention relates to a twin-bilobate storage tank storing low temperature liquefied gas. The present invention includes: a pair of unit tanks including an upper container part including a first inner space, and a lower container part combined with the lower part of the upper container part and including a second inner space; a combination unit combining a pair of the unit tanks while sides of the unit tanks stand to face each other; and at least one insulation member placed to surround a tank module formed by the unit tanks and the combination unit. According to the present invention, the twin-bilobate storage tank is capable of reducing the whole manufacturing costs by reducing the number of necessary insulation members, and increasing volumetric efficiency by reducing an idle space, as compared to an existing cylindrical storage tank with one container part or an existing bilobate storage tank with two container parts horizontally arranged. |
