Definitions

  • ABSTRACT OF THE DISCLOSURE A container for liquefied gases comprised of extensible sheets of the type described in U.S. Patent No. 3,184,- 094, but adapted to the construction of a tank which has a trapezoidal cross-section such as cargo tanks in the fore-and-aft ends of a ship.
  • the extensible sheets have zones in which non-intersecting but meeting corrugations bound an enclosed area and extend beyond such area to meet corresponding corrugations in an adjacent zone; to meet the required conditions for a trapezoidal tank, the enclosed areas near the common edge of two nonperpendicular sides of the tank are made rectangular rather than square, while the remaining enclosed areas are square.
  • This invention relates to containers and a method of making containers for the storage of liquids, especially very cold liquids such as liquefied natural gas.
  • such difiiculties may be overcome by constructing a container having walls comprising extensible sheets, each sheet having a plurality of zones in which zones non-intersecting but meeting corrugations entirely bound an enclosed area, the corrugations extending beyond each enclosed area to the sides of each zone, and the zones being placed side by side and end to end so that each of the corrugations in each zone meets a corrugation in a contiguous zone, comprising arranging all the zones so that all the common edges of the extensible sheets cross all the corrugations transversely and do not pass through an enclosed area, and where the common edge of two contiguous sheets is not perpendicular to the transversely directed boundary lines of the zones in one of the sheets, making the enclosed areas in that sheet rectangular so that the corrugations in that sheet meet those of the contiguous sheet at the common edge, and making the zones in the remaining parts of the sheets substantially square and also making their enclosed areas substantially square and locating those enclosed areas in the centres of the zones.
  • extensible sheet means a sheet which when fully restrained and subjected "ice to low temperatures will not suffer any stress exceeding its elastic limit.
  • the extensible sheets are preferably of metal, and if the container is used for the storage of a liquefied gas, metals which do not become embrittled at low temperatures should be used e.g., stainless steel, aluminium or aluminium alloys.
  • the corrugations can have any desired profile, that is they can be simple folds, curved, polygonalor V-shaped.
  • the extensible sheet can be made by welding or otherwise joining together a plurality of corrugated sheets, the edges of the individual sheets being transverse to the corrugations. However, perhaps the simplest and in any lase the preferred manner, is to weld together offset to one another, a plurality of large and small trays so that the upturned edges of adjarent trays welded together at their edges constitute the corrugations.
  • the ratio of a complete length of corrugation to that portion of the corrugation bounding the enclosed area may vary but convenient ratios are 511 or 4:1, i.e., when trays are welded together this means that the lengths of the large and small trays are respectively 4:1 and 3:1.
  • the zones are arranged so that in at least one pair of adjacent Walls at right angles to one another, the boundary lines of the zones in the sheets constituting the two walls are made parallel to and at right angles to the common edge. It is also preferable that this common edge be made coincident with the boundary lines of the neighbouring zones.
  • the zones are substantially square shaped. In the centre of these zones there will be substantially square enclosed areas, their bounding corrugations being at an angle to the boundary lines of the zones.
  • the zones are substantially square shaped in order that the corrugations in one zone shall meet those in an adjacent zone it is necessary for the corrugations when extending to the sides of the zones, to bisect the sides of the zones.
  • any wall is oblique with respect to an adjacent wall, it the corrugations in one extensible sheet are to meet those in the adjacent sheets, then some of the enclosed areas must be made rectangularand not squareshaped.
  • the other larger areas bounding the enclosed areas and common to four contiguous zones will also be rectangular and not square shaped.
  • the walls of the container comprise two series of zones.
  • the ratios of the total length of a corrugation to that portion of the corrugation bounding an enclosed area will be difierent for each series.
  • the series having the smaller ratio i.e., the bigger angle of inclination of the corrugations to the side of the Zone should be used near the oblique edges of the tank.
  • Suitable series are one having a ratio of total length of a corrugation to the length of a side of the enclosed area of :1 and the other a ratio of 4:1.
  • the container In order that the container is suitable for storage of very cold or very hot liquids, it must be mounted in a housing, which should preferably comprise thermal insulation.
  • the centres of the enclosed areas and also the large areas outside the enclosed areas should be pivotably mounted so that these areas are capable of undergoing angular rotary movement about their pivots in response to thermal expansions or contractions of the sheets.
  • FIGURE 1 shows a perspective view of a trapezoidal cargo tank of a cargo ship with tapered sides
  • FIGURE 2 shows a plan view of the tank with the sides collapsed and laid out flat
  • FIGURE 3 shows part of FIGURE 2 with the increments in the lengths of the rectangles shown
  • FIGURE 4 is an enlarged view of the area around the corner BAC in FIGURE 3,
  • FIGURE 5 shows a perspective view of a trapezoidal cargo tank of a cargo ship with tapered sides and a trunk
  • FIGURE 6 shows a plan View of part of the top wall and part of the sides laid out flat of the tank of FIG- URE 5,
  • FIGURE 7 is a view of a typical zone of an extensible metal sheet.
  • FIGURE 1 the forward end 2 and the port side 3 with the tapered bilge portion 4 of the tank 1 constructed of a series of large and small trays welded together, are shown.
  • the zones are indicated by broken lines and are all square in the forward end 2 and the port side 3 where the ratio of the total length of a corrugation to that portion of the corrugation bounding an enclosed area is 5:1.
  • these zones are parallelograms.
  • the full lines indicate the boundaries of the trays and the upturned edges of the trays project into the cargo tank, so that only the fiat back faces of the trays are visible.
  • the transversely directed boundary lines 8 in the aft end 7, the bottom wall 9, and the forward end 2 of the tank are at right angles to the common edges 10 and 11, the zones and the enclosed areas, such as the zone 12 and the enclosed area 13 in the aft end, are all square.
  • the transversely directed boundary lines 14 and 15 are not at right angles to the common edges 16, 17, 18 and 19, the enclosed areas in the bilge portions 4 and 6 near the common edges 16, 17, 18 and 19 are rectangular, such as those indicated by numerals 20 and 21.
  • FIGURES 3 and 4 of the accompanying drawings In calculating the sides of the rectangles necessary in the zones reference is made to FIGURES 3 and 4 of the accompanying drawings.
  • corrugations in both the bottom and bilge portions of the tank are arranged to meet the oblique edge AQ in the middle of the zones, i.e., they bisect lengths AB, BD and DF. If there were no adjustment of the shape of the enclosed areas in zones ACML, CENM and EGPN then the corrugations would have bisected the lengths AC, CE and EG and this is shown by broken lines.
  • FIGURE 5 the tank constructed of a series of large and small trays welded together is viewed from the forward end 40 and the starboard side 41, and the tapered bilge portion 42 and the trunk 43 are also shown. As with FIGURE 1 the zones are indicated by broken lines and the full lines indicate the boundaries of the trays, the upturned edges of the trays projecting into the cargo tank.
  • the ratio of the total length of a corrugation to that portion of the corrugation bounding an enclosed area is 4:1 and not 5:1.
  • This small ratio is also used for the portion of the tank (including the trunk) above the lines AB and CD.
  • the middle portion of the tank i.e., that portion below the lines AB and CD, but above the lines EF and FG the enclosed areas are smaller and the ratio is the same as the tank shown in FIGURES 1 and 2 i.e., a ratio of 5:1. It will be seen that the corrugations do not meet one another linearly along the lines AB, CD, EP and FG.
  • FIG. 6 which shows a plan view of the top of the starboard side
  • the lengths of the longer sides of the rectangles 44, 45, 46, 47 and 48 increase progressively as one proceeds along the oblique edge HI.
  • Rectangle 48 having one pair of sides about twice the length of the other sides, the enclosed area 49 is approximately square, but enclosed area 50 is rectangular in shape. Also it will be seen that the enclosed area 50 is in a zone one stage nearer to the edge HI than the series of zones in which enclosed areas 44, 45, 46, 47, 48 and 49 are to be found.
  • FIGURE 7 shows the physical construction of a typical zone, defined by broken lines 55, with the central small tray 56 joined to the adjacent larger trays such as 57 (only part of which lies within the zone) by corrugations 58 which can readily flex in a direction transverse to the length of the corrugation.
  • Each zone is fastened to the wall of a fixed outer structure at a point such as 61, in the central area of a tray 56 or 57, the mounting being such that under thermal expansion or contraction the zone rotates slightly about point 61, thus taking up the strain, as explained more fully in said US.
  • Each corrugation 58 extends, of course, into an adjacent and similar zone, as indicated by the full lines 58 in FIGURE 1, to define the respective larger trays which surround the small trays 56.
  • the trays and corrugations are preferably made of thin sheet metal joined by welding or in any other suitable fashion.
  • a container for the storage of very cold liquids said container having at least two adjacent sides which meet at an obtuse dihedral angle and a third side perpendicular to both of said two sides, each said side being constituted by an extensible sheet capable of absorbing stresses due to thermal expansion and contraction,
  • each extensible sheet having a plurality of zones
  • each zone including linear corrugations in the sheet material, said corrugations meeting, but not crossing, so as to bound an enclosed area within the zone,
  • corrugations being formed by the upturned edges of a plurality of large and small trays, said edges being welded together to provide said corrugations, said trays being offset to one another so that their edges form the said corrugations.
  • a container as claimed in claim 4 in which some of the adjacent walls of the container which are at right angles to one another, have the boundary lines of the zones in the sheets constituting such walls parallel to and at right angles to the common edge of such adjacent walls.
