The present invention relates to a liquefied gas storage tank and a marine structure including the same. The liquefied gas storage tank comprises a buffering partition installed within the liquefied gas storage tank and disposed to be adjacent to a side wall of the liquefied gas storage tank; a one-directional watertight door provided in a portion of the buffering partition and opened and closed in a direction toward the side wall; a vertical support supporting and fixing the buffering partition; and a damping unit formed by the side wall and the buffering partition and reducing a sloshing impulsive load applied to the side wall when a storage space of the liquefied gas storage tank is filled with the liquefied gas supplied through the one-directional watertight door. In the liquefied gas storage tank and the marine structure having the same according to the present invention, since a sloshing impulsive load reducing device is installed to be adjacent to the side wall of the liquefied gas storage tank, a sloshing impulsive load applied to the side wall of the liquefied gas storage tank due to a sloshing phenomenon can be reduced, securing stability of the liquefied gas storage tank and realizing an extra-large liquefied gas storage tank. Also, since the sloshing impulsive load reducing device can be partially installed in the liquefied gas storage tank, there is no need to deform a structure of the liquefied gas storage tank. |
