Abstract
Abstract A thermally insulated container for liquefied natural gas is constructed in a ship and has corrugated walls. The corrugations in the bottom, side and top walls extend longitudinally of the ship while those in the end walls extend vertically. The side and top walls are supported from the ship''s structure by sliding connections, while the end walls are interconnected by tie-rods. Thermal contraction of the walls on filling the container is accommodated by a reduction in the length of the tank in the length direction of the corrugations and by deformation of the corrugated walls transversely of the corrugations. Vertical contraction and expansion of the end walls is accommodated by elastic deformation of the top wall which is left unsupported in the regions adjacent the end walls.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
75 words
A low-temperature container for a ship, the container having corrugated top, bottom, side and end walls, in which the corrugations in each wall are uni-directional, the corrugations of the end walls are vertical while the corrugations in all the other walls all run lengthwise of the ship, and the side walls are sEcured to the ship''s hull by spaced sliding connections permitting relative movement in the length direction of the corrugations in the side wall.
Claim 2
Dependent Claim
75 words
A low-temperature container for a ship, the container having corrugated top, bottom, side and end walls, in which the corrugations in each wall are uni-directional, the corrugations of the end walls are vertical while the corrugations in all the other walls all run lengthwise of the ship, and the side walls are sEcured to the ship''s hull by spaced sliding connections permitting relative movement in the length direction of the corrugations in the side wall.
Claim 3
Dependent Claim
75 words
A low-temperature container for a ship, the container having corrugated top, bottom, side and end walls, in which the corrugations in each wall are uni-directional, the corrugations of the end walls are vertical while the corrugations in all the other walls all run lengthwise of the ship, and the side walls are sEcured to the ship''s hull by spaced sliding connections permitting relative movement in the length direction of the corrugations in the side wall.
Claim 4
Dependent Claim
75 words
A low-temperature container for a ship, the container having corrugated top, bottom, side and end walls, in which the corrugations in each wall are uni-directional, the corrugations of the end walls are vertical while the corrugations in all the other walls all run lengthwise of the ship, and the side walls are sEcured to the ship''s hull by spaced sliding connections permitting relative movement in the length direction of the corrugations in the side wall.
Claim 5
Dependent Claim
42 words
A container according to claim 1, in which the end portions of the top wall are free to deform resiliently to accommodate vertical expansion and contraction of the end walls while the remainder of the top wall is supported against upward movement.
Claim 6
Dependent Claim
41 words
A container according to claim 1, in which pads of load-bearing insulating material are interposed between walls of the container and adjacent portions of the ship''s structure with freedom for sliding movement of the corrugated wall portions longitudinally of the corrugations.
Claim 7
Dependent Claim
17 words
A container according to claim 3 in which the pads have nose portions engaged in the corrugations.
Claim 8
Dependent Claim
24 words
A container according to claim 3 in which the pads make interlocking sliding connection with ribs extending longitudinally of the corrugations and projecting therefrom.
Claim 9
Dependent Claim
24 words
A container according to claim 3, in which the outer ends of the pads bear slidably against guide channels secured to the ship''s hull.
Claim 10
Dependent Claim
25 words
A container according to claim 1, in which the corrugated walls of said container are built up from extruded panels, adjacent panels being welded together.
Claim 11
Dependent Claim
28 words
A container according to claim 1, in which the corrugated walls are built up from rolled sheet panels having the corrugations rolled therein, adjacent panels being welded together.
Claim 12
Dependent Claim
31 words
A container according to claim 1 in which the two end walls are stiffened by transverse beams, the transverse beams at opposite ends being interconnected by tie-rods extending through the container.
Claim 13
Dependent Claim
44 words
A container according to claim 1, in which two adjacent mutually inclined walls having their corrugations running in the same direction are joined by a curved section also formed with corrugations running in the said direction, said walls being tangential to said curved section.
Claim 14
Dependent Claim
32 words
A container according to claim 10, in which the curved corrugated wall section is slidably supported on pads which in turn are slidably supported in curved guide channels secured to the hull.
Claim 15
Dependent Claim
23 words
A container according to claim 8, in which the connections comprise channel-section clips having inwardly turned edges received in grooves in support pads.
Claim 16
Dependent Claim
26 words
A container according to claim 1 in which the corrugations in the walls comprise substantially plane front and rear walls interconnected by substantially plane sloping walls.
Claim 17
Dependent Claim
30 words
A container according to claim 1 and including an inner liner in said container, said liner being secured at joints in the liner to the inner walls of the container.
