Definitions

  • FIG. 1 CRYOGENIC INSULATION SYSTEM Filed Nov. 16, 1964 FIG. 1
  • cryogenic insulation system of this application is constructed from groups of prefabricated, dimensionally stable primary and secondary barrier panels connected side-by-side to define an inner and outer liquid-tight shell.
  • the prefabricated panels constituting the inner shell employ a material which has a very low coefficient of thermal expansion. The use of this material insures that the inner panels, though restrained, -will not be subjected to undue thermal stresses upon contact with the cryogenic cargo to be contained in the system.
  • the present invention relates to insulation systems and, more particularly, to integral insulation systems used in the storage and marine transportation of liquefied natural gas cargoes at atmospheric pressures under which conditions the liquefied natural gas cargoes are at cryogenic temperatures.
  • the containers must be capable of preventing heat losses which would lead to subsequent volatilization of the stored liquefied gas and of withstanding the internal stresses that may be induced therein by the large temperature gradients through the outer relatively warm walls of the ship to the supercooled inner surfaces of the container.
  • Certain conventional arrangements for transportating liquefied gases have involved the use of an aluminum or a stainless steel storage tank constituting a primary liquidtight barrier independently supported within an insulated chamber and separated therefrom by a secondary liquidtight barrier, the requirement of two barriers being dictated by well accepted safety practices and the provisions of certain regulatory codes.
  • so-called integral systems have been employed to achieve the same ends, in which the aforementioned primary and secondary barriers are directly superimposed and are supported by an enveloping structure, such as the walls of a cargo hold formed in a ships hull.
  • the above-mentioned systems invariably include some form of mechanical compensation, usually in the nature of expansion joints, to accommodate the normally contractive effects of the supercooled cargoes on the container structure itself.
  • a new and improved cryogenic insulation system which requires no mechanical expansion joints or the like.
  • a cryogenic cargo container embodying the new and improved system is constructed from groups of prefabricated, effectively dimensionally stable primary and and secondary barrier panels. Superimposed end-to-end, side-by-side arrays of each group of panels define two distinct liquid-tight barriers.
  • these prefabricated panels may be mounted progressively and with relative ease to a supporting structure such as a tanker cargo hold to define a new and improved closed cryogenic cargo container.
  • the panels comprising the secondary barrier are generally similar to the fiberglas reinforced polyester and polyurethane foam, thermal insulating panels first disclosed in the copending Harold R. Pratt et al. application Serial No. 394,287 filed Sept. 3, 1964, for Insulation System, and are effectively dimensionally stable, while in accordance with specific aspects of the present invention the primary barrier panels are in the nature of effectively dimensionally stable triplex panels formed by sandwiching a honeycomb core between spaced high nickel alloy steel sheets, possessing approximately 35.5 percent nickel and available commercially under the trade designation of Invar. The Invar sheets are held in a frame made of similar high nickel alloy steel.
  • the primary and second-ary barriers are integrally united by an intermediate liquid-tight barrier of epoxy adhesive thus providing a resultant structure having three liquid-tight barriers.
  • the importance of the impermeable barriers is to preclude cryogenic cargoes from contacting the supporting steel structure or ship hull and causing the embrittlement thereof.
  • the effectively dimensionally stable panels used in fabricating the new and improved cryogenic container are themselves non-embrittling, remaining relatively ductile at the supercooling temperatures of liquefied natural gases.
  • a further important aspect of the invention resides in the relatively high degree of fail safety obtained.
  • the nature of the construction and superimposition of the primary and secondary panels, with an interposed liquidtight intermediate barrier, is such that a failure in one will not cause a failure in the other.
  • this high degree of fail safety is further enhanced by providing a new and improved leakage system which includes a unique gas detection network which is an integral part of the primary barrier. More specifically, each of the honeycomb cores and each frame member of the triplex panels defines a passage therethrough which is linked to the passage of adjacent panels. Tthe interconnected passages are in turn associated with a gas detector which continually monitors the detection network for the presence of gas, which is, of course, an indication of the development of a leak.
  • FIG. 1 is a cross-sectional view of an insulated container, embodying the concepts of the present invention in a cargo hold of a ship;
  • FIG. 2 is an enlarged fragmentary cross-sectional view, taken along line 2-2 of FIG. 1, showing details of construction of the new and improved integral insulation system for the transportation of cargoes at cryogenic temperatures at atmospheric pressures;
  • FIG. 3 is a fragmentary perspective view of a new and improved, dimensionally stable, triplex primary barrier panel.
  • the cryogenic insulation system of the present invention is directly and fixedly supported by the secondary insulating barrier and is characterized as an integral system.
  • the supporting structure for a new and improved cryogenic cargo container 9 is the mild steel plate 10 of the cargo hold 11 of a dou-ble-hulled tanker 12.
  • the integral insulation system includes a secondary liquidtight barrier in the form of a continuous thermal insulating layer 13 supported in an end-to-end, side-by-side relation by the inner hull structure 14 of the ship and a primary liquid-tight barrier 15 superimposed upon the secondary barrier 13 and directly, fixedly anchored thereto.
  • the continuous, effectively dimensionally stable, secondary barrier 13 is established by securing stepped insulating panels 16 through mounting flanges 17 extending peripherally outwardly from base portions thereof, to the inner hull plate 11 by means of a nut 18, a clamping washer 19, and a Nelson stud 20.
  • the insulating panels 16 are generally similar to those dimensionally stable panels disclosed in more detail in the above-identified copending application of Harold R. Pratt et al. More specifically, the insulating panels 16 are approximately five feet by twentyfive feet in size, are generally symmetrical in shape (FIG. 2 showing opposite sides of two adjacent insulating panels), and include fiberglas reinforced polyester shells 21 filled with polyurethane foam 22. Each gap 23 formed between opposing faces 24 of adjacent insulating panels 16 is filled with a matingly stepped plug piece 25 having, similarly to the panels 16, a fiberglas reinforced polyester shell 26 filled with polyurethane foam 27 and being similarly effectively dimensionally stable.
  • the secondary barrier 13 defined by the end-to-end and side-'by-side array of insulating panels 16 and plug pieces 25, is made continuous and liquid tight by the bonding of the plug pieces 25 to the opposing stepped faces 24 of adjacent insulating panels by a suitable adhesive sealant 28.
  • a suitable adhesive sealant 28 As set forth in more detail in the beforementioned Pratt et al. application, the above-described insulating secondary barrier 13 is effectively dimensionally stable and will not undergo deleterious contraction when subjected to the extreme temperatures (e.g., --258 F. for liquefied methane) encountered in the cryogenic environments of liquefied natural gases.
  • a cargo resistant, primary barrier is formed by a plurality of dimensionally stable triplex panels 30, each hav ing a generally rectangular shape defined by a peripheral frame member 31 fabricated from an extruded C-shaped channel having an outer flange 37 and an inner flange 38 connected by a web 39.
  • the triplex primary barrier panels 30 include inner and outer metallic sheets 33, 32, respectively, which, in accordance with the principles of the present invention are also made from a dimensionally stable metal and are welded or otherwise suitably united with the frame members 31.
  • the sheets 32, 33 are maintained in a predetermined spaced relation, advantageously of approximately one-fourth to onehalf inch, and the panel 30 is strengthened by an intermediate honeycomb core structure 34 advantageously of phenolic-impregnated paper, fiberglas reinforced polyester, aluminum or the like.
  • honeycomb core 34 enhances its insulating properties by providing dead air space 35 therein.
  • the frame member 31 and sheets 32, 33 are fabricated from a high nickel alloy steel, one having a nickel content of approximately 35.5 percent and having a sufficiently low coeificient of contraction (approximately zero percent) to be characterized as being effectively dimensionally stable. More specifically, such an alloy steel is commercially available under the trade name Invar from the International Nickel Co., Inc., and has an ultimate strength of 100,000 p.s.i. Of prime importance for its use in the contemplated cryogenic applications in which severe temperature gradients are encountered through the walls of the container and between laden and unladen conditions, the thermal stress induced in Invar materials for a temperature variation from ambient of 350 F. is approximately 5,000 p.s.i.
  • the Invar triplex panels are advantageously approximately four feet by twenty-five feet (the former dimension being dictated by the widths of Invar sheet stock commercially available) and include Invar sheets 32, 33 of .025 inch thickness.
  • the triplex primary barrier panels 30 are firmly and fixedly anchored to the secondary insulating barrier 13, in a general end-to-end, side-by-side array without the employment of any expansion joints or the like, such as have been commonly employed heretofore in cryogenic containers of this type.
  • selected panels and plug pieces of the dimensionally stable insulating barrier 13 include moldedin, tapped Invar anchor blocks 36 to which the outer flanges 37 (which advantageously may be overlapped and interlocking as shown) of the frame members are tightly fastened by Invar bolts 40.
  • the mounting of the triplex panels to the underlying secondary barrier 13 is made more secure by the inclusion of a continuous layer of adhesive sealant 45, such as epoxy, therebetween, which layer constitutes an intermediate liquid-tight barrier, enhancing the safety and reliability of the container 9.
  • adhesive sealant 45 such as epoxy
  • the inner Invar sheets 33 include flap portions 41 extending beyond the periphery of the frame 31 at two or more edges thereof.
  • the flap portions which advantageously are flexible before final assembly, may be infolded during the installation and alignment of the triplex panels upon the secondary barrier to facilitate the same. Thereafter, the flap portions 41 may be unfolded into overlapping relation with adjacent panels.
  • the overlapped Invar sheets are Welded together as shown at 42 and, as should be understood, thereby define a continuous, effectively dimensionally stable primary barrier 15.
  • the honeycomb structure 34 is provided with a series of perforations or orifices 46 in communication with ports 47 formed in opposite web portions 39 of the frame 31.
  • each of the triplex panels 30 thus provides a continuous passage therethrough, which passage directly communicates with the passages formed in the adjacent triplex panel to establish, in accordance with the inventive principles, a leakage detection network.
  • a gas detector 48 is directly linked with the established detection network, through piping 49 and an opening 50 formed in the primary barrier, for the immediate sensing of cargo in the detection network.
  • the new and improved cryogenic container possesses an unusually great degree of fail safety.
  • the direct mounting of dimensionally stable primary and secondary barrier panels, with an interposed liquid-tight barrier ensures that a failure in one barrier will not result in the failure of the other.
  • the novel gas detection system employing individual primary barrier panels as conduits in a detection network, enhances the safety and reliability of the complete system.
  • a secondary barrier is established in a progressive fashion from the prefabricated insulating panels and, then, the prefabricated primary barrier panels are progressively anchored thereto by bolts and an intermediate epoxy barrier, to establish generally a primary barrier. Thereafter, completion of the primary barrier and the container may be accomplished with relative ease by uniting the flap portions of the Invar primary barrier panels to adjacent panels.
