Definitions

  • the present invention relates to lbarge constructions, and more particularly to barges adapted to transport cryogenic cargoes, such as liquefied natural gases at atmospheric pressures.
  • liquefied gas maintained at atmospheric pressures have extremely low vaporization points, ranging from about 435 F. for liquefied hydrogen, to -28 F. for liquefied ammonia, and these unusually low temperatures of the liquids present certain problems.
  • the vessels must be sufficiently thermally insulated to be capable of preventing heat losses which would lead to subsequent vaporization of the stored liquefied gas. They also must be of sufficient strength in the cold condition to withstand the often substantial internal stresses that may be induced herein by the large temperature gradients through its walls.
  • the present invention represents an entirely new approach and an improved solution to the problems associated with the marine tarnsportation of liquefied gases at cryogenic temperatures.
  • the ship, the thermal insulation, and the cryogenic container are fabricated as one and the same from special stepped plastic structural members or panels, made in accordance with general precepts set forth in detail in my copending application Serial No. 394,287, filed September 3, 1964, for Insulation System.
  • the plastic panels possess suflicient insulating and strength properties to prevent vaporization of the liquefied gas and to retain the integrity, seaworthiness, and cargo-impermeability of the ship.
  • the insulated cryogenic container of the invention is built in the general form of a closed barge, using a series of stepped, interlocking plastic panels.
  • the panels themselves are formed of fiberglass reinforced polyester resin shells filled With foamed polyurethane.
  • matingly stepped panels is made fast and liquid-tight by means such as an epoxy adhesive.
  • the new barge functions in the multiple capacities of what heretofore required several distinct structural entities, i.e., a container system, an insulating system, and a ship, which were themselves interrelated by sometimes complicated mounting systems to accommodate difierential rates of expansion.
  • a container system i.e., a container system, an insulating system, and a ship
  • the barge is constructed entirely from plastic, the elimination of steel from the structure obviates the requirement for additional or secondary barriers and/ or insulation to protect the steel from the cryogenic cargo.
  • a multiple-functioning barge may be constructed in accordance with the invention with a significant savings in material and labor costs in comparison with conventional marine transportation systems for cryogenic cargoes.
  • FIG. 1 is a longitudinal cross-sectional View of a new and improved barge embodying the inventive concepts
  • FIG. 2 is a plan view of the barge shown in FIG. 1;
  • FIG. 3 is an enlarged cross-sectional view of the new and improved barge taken along line 3-3 of FIG. 1;
  • FIG. 4 is an enlarged, fragmentary, cross-sectional view of the barge taken along line 44 of FIG. 3;
  • FIG. 5 is a further enlarged, fragmentary, cross-sectional view showing details of construction of the walls of the new and improved barge.
  • the barge of the present invention is generally symmetrical in overall shape and includes a hull having forward and after hull portions 10 and 11, v
  • the hull itself is closed by a deck 13 to define a cargo space which may be divided by transverse bulkheads 14 and a longitudinal bulkhead 15 (FIG. 3), to define a plurality of cargo holds 15a. Access to the cargo space is had through hatches 16 (FIG. 2) formed in the deck 13.
  • the entire barge structure is fabricated from plastic panels 17 which act in a dual capacity as thermal insulators and rigid load bearing structural members. More specifically, and as shown in FIGS. 4 and 5, each of the plastic panels 17 includes a shell 18 of polyester resin reinforced with suificient fiberglass to impart significant and adequate structural strength, which shell is filled with a cellular insulating material, such as polyvinylchloride or polyurethane foam 19.
  • a cellular insulating material such as polyvinylchloride or polyurethane foam 19.
  • the principal inner and outer shell surfaces are joined and held in spaced relation by a plurality of integral transverse web sections 24.
  • the connecting web sections divide the individual panels into a plurality of sections or cells and, in conjunction with the foam material filling the cells, impart significant structural rigidity to the panels.
  • the peripheries 20 of the respective panels 17 are of predetermined stepped configuration to interlock matingly with one another, in accordance with the principles of the invention.
  • the panel margins advantageously include peripheral flanges 25 received in corresponding recesses 26 in adjacent panels.
  • the stepped peripheral configuration of the panels, in conjunction with the flanges 25, provides substantial longitudinally and transversely oriented surface areas for bonding, to provide a liquid-tight structural sound joint.
  • Special, stepped connecting pieces, such as 3 indicated at 27, 28 in FIG. 3, may be utilized to join panels at corners and other places of intersection.
  • the construction of the connecting pieces is of insulating foam material encapsulated in a shell of polyester resin and fiberglass, similar to construction of the panels themselves.
  • the hull walls 22 of the barge, as well as the bulkheads 14, 15 and the deck 13, are fabricated from groups of contiguously arrayed panels 17 united at their peripheries by an interposed epoxy adhesive 21 or the like (FIG. to form stable, liquid-tight joints 23.
  • the completed plastic structure, a navigable barge is capable of bearing the hydrostatic loads imposed by the liquefied gas cargoes as well as capable of withstanding the induced thermal stresses of the cryogenic cargoes.
  • a barge may be constructed with minimum effort and material, since the barge itself functions as a thermally insulated container.
  • significant economies in production are realized, by incorporating the vessel, cargo container, and thermal insulation into a single autonomous unit rather than having three or more separate structures.
  • the new and improved plastic barge is intended primarily for still water service, such as in rivers and canals, and is designed to possess sufficient structural integrity for that purpose and, additionally, to possess sufficient thermal insulating properties to prevent the undue warming and consequent volitalization of liquefied gas cargoes.
  • This advantageous structure is achieved without the use of metallic or like embrittleable structural members.
  • a rigid barge for transporting cyrogenic cargoes at atmospheric pressure comprising (a) a deck portion,
  • said hull and deck portion being substantially entirely fabricated from rigid load bearing insulation panels
  • said panels also having fiberglass reinforced polyester resin shells filled with a suitable insulating foam and a plurality of integral transverse web sections between the principal inner and outer shell walls,
  • said integral web sections being constructed of fiberglass-reinforced-polyester and of sufiicient strength to contribute to the overall structural rigidity of said insulation panels.
  • the barge of claim 1 including (a) adhesive means bonding together adjacent panels at their matingly stepped edges in an effectively continuous, stable and liquid-tight manner.
