Claim Text:
1. A liquefied natural gas (LNG) storage container comprising: an inner shell configured to store LNG inside; an outer shell configured to enclose the inner shell such that a space is formed between the inner shell and the outer shell; a first inner support fixed to an outer surface of the inner shell at a first location; a second inner support fixed to the outer surface of the inner shell at a second location that is distanced from the first location along an axis; a first outer support fixed to an inner surface of the outer shell and aligned with the first inner support; a second outer support fixed to the inner surface of the outer shell and aligned with the second inner support; and a corrugation provided in the inner shell between the first location and the second location along the axis, wherein the first inner support is connected to the first outer support and the second inner support is connected to the second outer support such that movement of the first inner support relative to the second inner support along the axis is substantially limited while permitting movement of the first inner support relative to the first outer support along a first direction perpendicular to the axis and also permitting movement of the second inner support relative to the second outer support along a second direction perpendicular to the axis, and wherein with substantial limitation of relative movement between the first and second inner supports, the corrugation is configured to absorb thermal expansion and contraction of the inner shell along the axis.
