  • the invention is exclusively concerned with containers of the kind, known as integrated tank containers.
  • containers of the kind known as integrated tank containers.
  • the insulation lines, and is itself supported by, a'relatively rigid supporting shell, so that the insulation directly transmits to the supporting shell all the pressure exerted by the fluid upon the walls of the membranetank.
  • Containers as defined in the preceding paragraph will hereinafter be denoted containers of the kind specified".
  • the walls of the membrane tank of a container of the kind specified will, unless prevented by'external'means, contract substantially when contacted by the cold liquid.
  • the invention is exclusively concerned with containers of the kind specified and of the type in which the membrane tank is held against overall dimensional change due to thermal stress so that the overall dimensions of the membranetank remain unchanged relative to the supporting shell and the membrane tank remains in contact with and supported by the insulation.
  • Containers as defined in the preceding paragraph will hereinafter be denoted containers of the type specified".
  • the loads upon the means holding and anchoring the membrane tank against overall dimensional change may be considerable. There may be considerable loads due to thermal stresses.
  • the container is mounted in the hold of a marine taker, at least some of the walls of the membrane tank are subject to stresses caused by ship strains-when the taker is at sea which also produce additional loads upon the means anchoring the membrane tank against overall dimensional change.
  • the means anchoring the membrane tank against overall dimensional change due to thermal stresses must be designed to withstand such additional loads.
  • the means anchoring the membrane tank against overall dimensional change are preferably not directly connected to the hull of the tanker because this would interrupt the insulation and provide heat/cold bridges which would locally reduce the temperature of the hull with dangerous consequences.
  • the insulation in in designing containers of the type specified it is necessary to ensure that the insulation is capable of withstanding the hydrostatic loads imposed upon it by the membrane tank and also, when mounted in a ship, the stresses caused by the ship's strains at sea.
  • the insulation must also be substantially nondeformable when subjected to temperature change and there must be no heat/cold bridges therethrough.
  • the means anchoring the membrane tank against overall dimensional change must not prejudice the thermal insulating properties of the insulation.
  • a secondary barrier against the leakage of fluid should the pri-. mary barrier membrane tank fail.
  • a secondary barrier may be in the form of a further membrane tank, e.g. of thin metal, enclosing the primary barrier membrane tank and supported by load-bearing insulation.
  • the secondary barrier is constituted by the insulation supporting the primary barrier membrane tank, or is in the form of a nonmetallic, e.g. plywood, sheet incorporated in the insulation.
  • the insulation shall be reliable and shall not be interrupted by heat/cold bridges which might also act as leakage points.
  • the container has in identical primaryand secondary membrane tank barriers of thin sheet metal each supported by a surrounding wall of insulation.
  • Each such wall consists of a framework supporting rigid hollow blocks containing granular insulation and free freely mounted one upon the other.
  • the corners of each of the. primary and secondary membrane tank barriers are anchored by means extending from each corner through the insulation to the supporting shell.
  • This arrangement has a number of disadvantages, amongst which is the fact that the two walls of insulation are constituted by free blocks which may move. That is to say the blocks of each wall of insulation may move so that their membrane tank supporting faces are no longer in alignment and do not provide a smooth surface so that the membranefiank may fracture. This could .be dangerous particularly'where, as is primarily the intention, the container is used in a ship.
  • Another disadvantage is the interruption of the insulation by the comer anchoring means of the membrane tanks, which form heat/cold. bridges.
  • a single membrane tank primary barrier supported by a'solid wall of insulation constituted by rigid wood panels or blocks which are each individually fixed to form a substantially continuous wall, so that their membrane tank supporting faces remain in a common plane and provide a permanently smooth supporting face for the membrane tank.
  • the insulation itself constitutes or incorporates a nonmetallic secondary barrier and each block is substantially fluid-impermeable and the gaps between adjacent panels or blocks are filled with sealing material and closed by scabs connecting the panels so that the insulation remains a fuidtight secondary barrier notwithstanding contraction of the panel the panels.
  • the anchoring means for the membrane tank are spaced at intervals on the insulation along and across the walls of the membrane tank in such a way that they support the loads of the membrane tank along each wall.
  • a disadvantage of this arrangement is that the corners of the membrane tank may not be maintained rigid and may be liable to fail.
  • the membrane is held by means of angle-section anchoring members of rigid material extending along the corners of the membrane tank and secured to a rigid framework disposed within the insulation and secured to the rigid shell.
  • This arrangement has the disadvantage that the accommodation of the framework additional to the insulation is more complicated and the fact that the framework is secured to the insulation actually in the corner of the latter vitiates against the requisite expansion and contraction of the insulation.
  • An object of the present'invention is to overcome the disadvantages of the prior proposals and meet the above stated problems by the provision of a container of the type specified having an integrated structure in which the individual require ments of the insulation, the membrane tank and the anchoring means for the latter are suitably allied to one another.
  • a specific aim of the invention is to provide a marine tanker equipped with one or more containers, the membrane tank walls of which are at all times supported by the surrounding insulation and in which the membrane tank and particularly the comers thereof are less liable to deformation and fatigue failure.
  • the present invention provides a container of the kind and type specified in which the corners of the membrane tank are anchored to the corners of the insulation by means of rigid angle-section anchoring members extending externally along the corners of the membrane tank and secured to the corners of the insulation, whereby the corners of the membrane tank are rigidly anchored to the insulation and are held against any appreciable deformation.
  • the invention provides a container of the kind and type specified in which: (a) the load-bearing thermal insulation is secured to the supporting shell against movement away from the shell and is such that when subjected to change in temperature it does not deform (except to a limited extent at the corners) so that it permanently provides a smooth supporting surface for the membrane tank; (b) the corners of the membrane tank are anchored to the corners of the insulation by means of rigid angle-section anchoring members extending externally along the comers of the membrane tank and secured to the corners of the insulation; and (c) at least the corners of the insulation are of materials of tensile and compressive strength sufficient to transmit to the shell the loads upon the anchoring members, whereby the corners of the membrane tank are rigidly anchored to the insulation and are held against any appreciable deformation.
  • the idea of the invention is that, instead of the anchoring members being connected with the supporting shell by means extending through and additional to the corners of the insulation, the anchoring members are merely connected to the corners of the insulation which are relied upon to transmit the loads to the supporting shell. In this manner the problems, presented by additional means extending-.through and interrupting and forming heat/cold bridges through the corners of the insulation, are avoided.
  • corner is used throughout this specification to mean the length of the junction formed by the edge portions of two adjoining walls, or portions of walls, either, of the membrane tank or of the insulation or of the complete container.
  • wall includes the top and bottom.
  • the integrated containers in accordance with the invention may be of any geometrical shape, They will usually be prismatic or parallelepipedic but may be of a more complex shape with plane walls or relatively inclined plane wall portion, for example, for fitting into the bottom of the inner hull of a tanker.
  • the containers may also be stepped in the sidewalls or bottom or top walls so that the container is of progressively different cross-sectional sizes, for example for closely fitting within the forward or aft parts of a tanker.
  • the membrane tanks will have corners formed at the junction of the edge portions of adjoining walls or portions of walls. Adjacent walls may form a dihedron with a junction in the form of a straight line or edge. However, the junction may be in the form of a curvilihear edge line.
  • the angle of the dihedron may be substantially orthogonal or right but particularly in the case of a tank having relatively inclined wall portions, the angle may be of any value, for example, an obtuse or acute angle, depending upon the geometrical shape of the tank.
  • Some of the corners in a tank of any geometrical shape may be in the form of inner comers or solid angles which are internal or entrant.
  • the tanks, and particularly those in which the sidewalls and top or bottom walls are stepped or those having a narrow upper extension or trunk have dihedral external corners which are salient or reentrant.
  • angle section anchoring members are rigid enough to be substantially nondeformable and to render substantially invariable the angle of the corners of the membrane tank, that is to say the angle between the walls or portions thereof constituting the corners, thereby reducing the possibility of fracture of the corners of the membrane tank.
  • the members anchor the membrane tank against overall dimensional change due to thermal stress and are, for convenience, designated anchoring members throughout this specification, they also rigidly support and hold the corners of the membrane tank against any substantial change in the angle of the corner.
  • anchoring members are secured to the insulation at short distances from the line junction of the internal corners of the insulation so as not to interfere with the deformation of these corners under expansion and contraction of the insulation.
  • Each limb of the angle-section anchoring member extends a short distance along the face of the insulation away from the line junction of the comer and is secured at a distance from the line junction, e.g. by means of bolts or screws, to rigid load-bearing insulation blocks, e.g. of hardwood, rigidly secured upon the face of the insulation in such manner, e.g. by adhesive, as not to prejudice the fluid-tightness of the insulation.
  • the blocks extend or are distributed along each of the edge portions flanking the line junction constituting the corner of the insulation adjacent the corner of the membrane tank. Because the blocks supporting the two limbs of each anchoring member are' spaced at distances from the line junction of the corner along the adjacent walls of the insulation, there is a gap between the anchoring members and the corner of the insulation which accommodates the deformation of the latter.
  • a further feature of the invention is that the tensile load in any wall of the membrane tank is taken partly by that wall of the insulation extending parallel to and associated with said wall of the tank, and partly by that wall of the insulation extending perpendicularly thereto. Part of the tensile load in any wall of the membrane tank is taken in shear through the wall.
  • the membrane tank may be of any suitable cold-resistant flexible material, e.g. metal, which is not subject to cold embrittlement at the temperature of liquefied gases at atmospheric pressure.
  • metal is intended to include alloys.
  • the membrane tank may be of metal, e.g. stainless steel, or an aluminum alloy, which does not have an unduly low coefficient of thermal expansion but is formed with expansion formations, such as corrugations or dimples, in two directions providing excess metal to accommodate contraction.
  • the membrane tank may be of metal, such as the 36 percent nickel steel known as lN- VAR, which has a very low coefficient of thermal expansion and which may or may not require to be provided with expansion formations.
  • the angle-section anchoring members may be of any appropriate metal, for example, stainless steel, an aluminum alloy, or lNVAR, of a suitable strength and thickness to provide the requisite rigidity. It is important that the material of the anchoring members shall be compatible, for example, in its coefficient of thermal expansion and in capability of welding, with the material of the membrane tank. Preferably, the same metal is used for both membrane and anchoring members although this is not essential providing that the metals can be welded to one another and have similar coefficients of expansion. in order to enhance the rigidity, each angle-section anchoring member may beprovided at intervals with external ribs or webs either formed integrally with the anchoring member or welded thereto.
  • each anchoring member extending along the length of a corner of the tank into a plurality of short members with gaps between the adjacent ends thereof.
  • the gaps will be closed in fluidtight fashion by thin plates bridging and welded to adjacent members and preferably formed to accommodate contraction and expansion.
  • these connecting plates are constituted by the corner pieces of the membrane tank itself.
  • the membrane tank shall have, disposed within the anchoring members comer pieces which form, with the walls, the complete fluidtight tank.
  • the membrane tank shall have, disposed within the anchoring members comer pieces which form, with the walls, the complete fluidtight tank.
  • the anchoring members comer pieces which form, with the walls, the complete fluidtight tank.
  • anchoring members do not form part of the membrane tank, although small portions of the members may form a seal.
  • the thermal insulation of the container of the invention must essentially form rigid load-bearing walls, of sufficient compressive strength to support against hydrostatic loads the walls of the membrane tank, and the loadbearing walls together form a complete structure which permanently remains fluidtight.
  • any suitable material(s) which meets the criteria specified above may be used, it is primarily the intention that the insulation shall be constituted by blocks or panels, e.g. of balsa wood, each individually secured to the supporting shell and the panels forming each wall are secured together to form a complete solid wall but in which some provision is made for limited deformation of the portions forming the corners of insulation.
  • the insulation is of the form described in U.S. Pat. No.
  • Insulation of this form is of sufficient tensile and compressive strength to transmit to the supporting shell the loads upon the anchoring members.
  • insulation of this form may be utilized to form the corners of the insulation, where both compressive and tensile strength is required and some other thermal insulation material having only the requisite compressive'strength e.g. a foamed plastic material, may be used to form the main portions of the walls of the insulation.
  • the insulation of the container shall constitute or incorporate a nonmetallic secondary barrier against the leakage of liquid.
