  • FIG. 1-10 A first example of a storage tank containment system 10 is shown in Figures 1-10.
  • the first example of a storage tank containment system 10 includes a storage tank 12 having a generally cubic configuration, with six geometric square sides oriented at substantially right angles with respect to one another.
  • the tank 12 is preferably constructed from twelve interconnected hollow or tubular walls (a single exemplary cylindrical-shaped wall 14 indicated in Figure 1). Though in the following examples, the interconnected tubular walls are cylindrically-shaped and have a closed, substantially circular cross-section, other hollow or tubular shapes are also possible.
  • the exemplary storage tank 12 includes four vertically oriented cylinder walls 16 positioned approximately 90 degrees apart from one another and eight horizontally oriented cylinder walls 18 disposed between, and rigidly connecting to, the ends of the vertical walls 16 at corner portions 20a.
  • the eight horizontal cylinder walls 18 include four lower cylinder walls 18a arranged at a bottom of the storage tank 12 and four upper cylinder walls 18b arranged at a top of the storage tank 12.
  • each of the vertical walls 16 and horizontal walls 18 can be the same length with substantially identical cross-sections and curvatures.
  • the axes 24, 26 and 28 intersect at a point (not shown) inside the corner portion 20a.
  • the vertical cylinder wall 16 and the two horizontal cylinder walls 18a extend along their respective axes and are generally connected at their respective distal ends 30, 32 and 34 at a joint 40 between the respective cylinder walls, closing off the interior fluid storage chamber 22.
  • the joint 40 includes a closure member 60 positioned to close a space or gap between the respective distal ends 30, 32 and 34 of the vertical cylinder wall 16 and the two horizontal cylinder walls 18a, as explained below, although other configurations for the joint 40 are possible.
  • the corners 20 may be rounded or spherical-shaped to more closely match the contour of the cylinder walls for manufacturing and/or assembly purposes.
  • the basic structure for the storage tank 12 is preferably composed of aluminum, although other materials, for example nickel steel, high strength pressure grade steel and other materials, known by those skilled in the art may be used. It is also understood that different components other than those described above and illustrated, as well as in different shapes and orientations, known by those skilled in the art may be used.
  • the constituent components of the storage tank 12 are rigidly and permanently joined together using a seam welding process in a manner to form a fluid- tight interior fluid storage chamber 22. For instance, the joints 40, 42 and/or 44 can be completed and sealed to form a fluid tight corner between the vertical 16 and horizontal 18 cylinder walls.
  • the configuration of the completed joints, as well as the processes for completing the joints, may vary according to one or more design, strength, manufacturing and/or other considerations. Examples of these and other joints between constituent parts of the storage tank 12 are explained with reference to Figures 6 A and 6B.
  • Figure 6A is a cross section of the joint 40 in Figure 5 A between the vertical wall 16 and a horizontal wall 18a.
  • the storage tank 12 is assembled prior to completing the joint 40 such that a space or gap is present between the respective distal ends 30 and 32 of the vertical wall 16 and the horizontal wall 18a prior to completing the joint 40.
  • a closure member 60 is sized and configured to substantially close the gap between the respective distal ends 30 and 32.
  • the closure member 60 extends along the joint 40, and as can be understood with reference to Figures 4 and 5 A, the closure member 60 has three generally annular, open ended ring shaped portions in the example corner portion 20a.
  • the closure member 60 can have other shapes that may vary depending upon its application in alternative corner portions and/or joints between other constituent parts of the storage tank 12.
  • the closure member 60 can have advantageous use where it is not feasible, cost effective or otherwise desirable to manufacture and/or assemble constituent parts of the storage tank 12 according to tolerances allowing for direct welding. Additionally or alternatively, the closure member 60 may be included to perform a strengthening or reinforcing function in the joint 40.
  • the respective distal ends 30 and 32 of the vertical wall 16 and the horizontal wall 18a are chamfered from both an interior side (facing the interior fluid storage chamber 22) and exterior side of the walls, such that a pointed vertex is formed at each of the distal ends 30 and 32, although the vertexes could alternatively be rounded, for example.
  • the illustrated closure member 60 is shaped with a rectangular cross section and oriented so that pointed vertexes oppose each of the points of the distal ends 56 and 58. In this configuration, four inwardly tapering grooves are formed.
  • two grooves are formed for receiving welds to join the vertical wall 16 to the closure member 60, and two grooves are formed for receiving welds to join the closure member 60 to the horizontal wall 18a.
  • the cross section of the closure member 60 can be differently sized or shaped, for example, depending upon the size of the gap to be closed. It will be understood that one or more of the distal ends 30 and 32 and the closure member 60 could be shaped and configured otherwise than specifically illustrated. For instance, the distal ends 30 and 32 and the opposing portions of the closure member 60 could alternatively be rounded, for example, and the distal ends 30 and 32 and the closure member 60 could be formed so that grooves are only formed that open to one of an exterior side or interior side of the walls 16 and 18a.
  • the respective distal ends 30 and 32 of the vertical wall 16 and the horizontal wall 18a are chamfered from both the interior side and the exterior side of the walls, such that a pointed vertex is formed at each of the distal ends 30 and 32.
  • Inwardly tapering grooves are formed by the opposing points of the distal ends 30 and 32, which are sized and shaped for receiving a weld to join the vertical wall 16 and the horizontal wall 18a.
  • the distal ends 30 and 32 could alternatively be rounded, for example, or could be formed so that a single groove is formed that opens to only one of the exterior side or the interior side of the walls 16 and 18a.
  • the disclosed storage tank containment system 10 includes additional external and/or internal structures configured to efficiently and effectively account for and manage the static and dynamic loads from a fluid contained within the storage tank 12, as well as the loads from the storage tank 12 as further described below.
  • a representative exterior support structure 100 connected to the outer surfaces of the storage tank 12 is illustrated in a first example with reference to Figures 1-3, 7 and 8.
  • the support structure 100 is generally positioned about an exterior of the walls 14 to provide radial support and/or reinforcement to one or more portions of the storage tank 12, in order to strengthen the storage tank containment system 10 against stress arising from movement of the fluid within the interior fluid storage chamber 22, as well as a stress from the bulk of the storage tank containment system 10 as a whole.
  • the first exemplary support structure 100 includes a plurality of first braces 102 (i.e., 102a, 102b, 102c, etc.), a plurality of second braces 104 (i.e., 104a, 104b, 104c, etc.), and a plurality of third braces 106 (i.e., 106a, 106b, 106c, etc.).
  • a base 150 is also used. It will be understood that certain constituent components of the support structure 100 and base 150 that are described and/or illustrated as discrete connected components could be integral, for example, and vice versa.
  • each of the braces 102, 104 and 106 are substantially planar members that extend outward from the storage tank 12 and have openings 108 (a representative opening 108 is indicated for the brace 102a) sized and shaped to closely circumscribe selected exterior portions of the storage tank 12.
  • the braces 102 and 104 are vertically oriented and horizontally spaced, and are aligned at right angles with respect to one another in parallel to the respective edges of the sides of the storage tank 12.
  • the braces 106 are horizontally oriented and vertically spaced, and are similarly aligned in parallel to the respective edges of the sides of the storage tank 12.
  • the braces 102, 104 and 106 are generally positioned and oriented to reinforce and provide radial support to selected outer portions of the adjacent horizontal and vertical cylinder walls 16 and 18 that respectively form the six sides of the storage tank 12.
  • the portions 120 similarly comprise vertically oriented braces 104 abutting the outwardly facing portions of the other two parallel lower cylinder walls 18a, so as generally circumscribe the bottom side of the storage tank 12, as well as parts of the other two opposing upright sides of the storage tank 12 than the braces 102.
  • the braces 104 also extend vertically to a position approximately at the middle of the two opposing upright sides of the storage tank 12.
  • the braces 104 are spaced horizontally such that an outer brace 104c of the braces 104 is positioned to extend upward along a vertical cylinder wall 16 in a radial direction from the vertical cylinder wall 16, as well as in abutment with a circumferential portion of a connected horizontal cylinder wall 18a.
  • the concentration of braces 102, 104 and 106 toward the lower bottom half of the storage tank 12 are used to fortify the lower portion of the storage tank 12 and its capacity for hydrostatic and other forces.
  • T-plates 103 are selectively connected to braces 102 and 104 perpendicular to the braces to form a T-shaped section for increased strength of the braces against buckling and other deformation.
  • concentrations of braces can be selectively incorporated into the base 150, for example, at a center of the bottom side of the storage tank 12.
  • the storage tank containment system 10 includes a base 150 for supporting the storage tank 12 on a rigid support surface, for example, a floor 168 of the cargo hold 160.
  • base 150 is formed by vertical braces 102 and 104 as best seen in Figure 2.
  • the peripheries 110 of the vertical braces 102 and 104 opposing the respective portions of the openings 108 that circumscribe the bottom of the storage tank 12 can form a substantially planar platform or surface to form a base 150, as shown in Figure 2, providing a flat footprint for the storage tank 12 to abut a flat floor 168 of the cargo hold 160.
