Abstract
Disclosed is a storage container for liquefied gas, for example, a storage cabin for marine equipment such as ships. A bottom wall of a storage container includes a bottom wall sealing layer including a central section and at least one annular section. The annular section includes a plurality of first sealing plates and a plurality of second sealing plates, which are alternately arranged in a circumferential direction. The first sealing plates have a circumferential size gradually reduced in a radially inward direction, and the second sealing plates have a circumferential size gradually expanded in the radially inward direction. The sealing layer of the storage container of the present disclosure may be made of standard parts with regular shapes, without requiring special shaped segments, which is simple to process and saves materials. Further, sealing connectors serving as universal parts may also be used between adjacent standard parts, and some sealing connectors of the present disclosure also have certain thermal expansion and contraction, which can provide a certain amount of cold shrinkage deformation for the sealing layers.
