Definitions

  • This invention relates to the ship transportation of extremely cold liquids in self-suflicient containers of large capacity, and it relates more particularly to a safety feature employed in a system of the type described for the purpose of maintaining control of the extremely cold liquid cargo which might inadvertently or otherwise escape from the containers, thereby to avoid the extremely dangerous conditions which would otherwise develop.
  • FIGURE 1 is a schematic sectional elevational view of a system which may be employed for the safe transportation of an extremely cold liquid
  • FIGURE 2 is a sectional elevational view similar to that of FIGURE 1, showing a modification in the safety means, and
  • FIGURE 3 is a similar sectional elevational view of a corner of a structure embodying a further modification.
  • This invention can best be illustrated by reference to the over-water transportationof natural gas in a liquefied state from a source of plentiful supply to an area where a deficiency exists. It will be understood that the concepts described will have similar application to ship transportation of other extremely cold liquids in large quantities, such as liquefied air, oxygen, hydrogen, nitrogen, and the like.
  • the liquified gas atabout atmospheric pressure is housed within a large tank of polygonal shape and formed of such materials as aluminum or alloys of aluminum, stainless or other high nickel or austenitic steels, copper or alloys of copper and the like which do not become embrittled at cryogenic temperatures.
  • the tanks are mounted within the hold space of the ship lined with a relatively thick layer of insulating material, as represented by blocks of balsa wood or other material having low heat conductivity.
  • the ship is preferably formed with an outer steel hull and an inner hull in closely spaced parallel relationship with the outer hull to define a confined space therebetween through which water or other fluid may be introduced or circulated for temperature control as well as for ballast.
  • a ship may roll by as much as 40 degrees in either direction in a bad sea, thereby to impose considerable shifting of the loads upon the walls of the tank and thereby also to impose problems with respect to maintenance of the liquids which find their way outside of the tank by reason of leakage, splash, or partial failure of the tank.
  • the metal storage tank is represented by the numeral 10 and the liquified gas stored therein is represented by the numeral 12.
  • the tank is illustrated as being housed within an insulated hull 14 of the ship lined to provide a relatively thick layer 16 of a structurally strong and dimensionally stable insulation, such as balsa wood.
  • the tank is provided with an inlet pipe 18 which extends into the tank through the top wall 20 for the introduction of liquid cargo into the tank and which is provided with a fiow control valve 22 for regulating the flow of vapors and fiuid therethrough.
  • a discharge pipe 24 extends downwardly through the tank to a point adjacent the bottom side for use in, the removal of liquid cargo, and it, too, is provided with a flow control valve 26 for regulating the flow of vapors of fluids therethrough and a vent pipe 25 extends into the tank into communication with the vapor space for release of vapors collecting above the liquid level.
  • a space 28 is provided between the side walls of the tank and the insulation 16 disposed outwardly thereof.
  • Each tank is provided with a receptacle 30 extending outwardly from the bottom side of the tank, such for example, as the pan'illustrated' in FIGURE 1 shaped to correspond with the cross-section of the tank and dimensioned to have a" length and width greater than the corresponding dimensions of the tank to span the bottom wall 32 and extend into the space 28 between the side walls of the tank and the insulation.
  • the side walls 34 of the pan extend upwardly into the space about the sidewalls of the tank to provide a trough 36 into which the liquid cargo escaping from the tank and flowing gravitationally downwardly along the side walls of the tank can collect.
  • the side walls 34 of the receptacle extend upwardly for a short distance beyond the bottom wall of the tank, it is preferred to dimension the side walls to extend beyond the lower quarter of the tank so as to retain liquid escaping from the tank and flowing gravitationally down the side, notwithstanding the angular movement of the ship at angles as great as 40 degrees responsive to the pitching and rolling movements of the shi its receptacle should be formed of materials which are impervious to the liquid cargo and insensitive to the cold of the liquid.
  • the receptacle can be fabricated of metal suitable for tank construction, or of wood or of plastic, with or without reinforcement.
  • the bottom wall 32 of the receptacle can rest on the floor 37 of insulating material, and the bottom wall of the tank can rest upon the .top surface of the bottom wall of the receptacle, or the tank'bot-tom wall can be supported in spaced relationship with the bottom wall of the receptacle as by means of beams 38 to provide a spaced I relation therebetween and thereby increase the capacity of the receptacle to retain liquid as illustrated in FIGURE 1.
  • the receptacle may constitute a side wall 34' and a bottom wall 32' dimensioned to correspond with the spaced relationship between said side wall 34' and the tank, and which is secured in sealing relationship to the lower edge of the tank to provide a receptacle in the form of a trough 36' which extends all about the lower edge of the tank, with the side wall of the container defining the inner wall of the trough, as illustrated in FIG- URE 2.
  • a receptacle which is not free standing but instead relies upon the insulation for support.
  • a membrane 34 such as a film of metal or plastics fixed to the lower part of the insulation surrounding the tank to form a receptacle.
  • the bottom wall of the pan can be constructed to provide recessed keyways dimensioned to be received in corresponding keyways in the supporting floor and into which the keys on the bottom side of the tank are received; or vice versa, the keys may be formed in the pan and floor for engagement into corresponding keyways provided in the bottom wall of the tank.
  • one or more drains 40 are provided in the bottom wall of the receptacle for connection by pipes 42 to the intake side of a displacement pump 44 by which the liquid is forced through a pipe 46 to the filling pipe 18, whereby liquid from the pan is returned to the tank, or to.
  • a pipe 47 having itsloutlet preferably extending rearwardly of the ship for dumping the liquid into the sea.
  • the tank rests upon the top surface of the pan, or when the receptacle merely constitutes the trough, it will usually be suflicient to locate the drain or drains in the base of the trough for communicating the liquid with the displacement pump.
  • one or more drains can be located in intermediate portions of the pan bottom wall, and such drains can be located advantageously in downwardly deformed basins or sumps for more complete drainage of liquid from the pans for return to the tank.
  • cryogenic liquids With such cryogenic liquids, it is preferred to make use of means for direct displacement of the liquid without drainage or other below deck installations thereby to avoid bottom connections.
  • sensing means such as electrodes 50 and 52, are provided in the base of the trough for initiating operation. of the displacement pump when the electrodes are contacted with liquid, thereby automatically to recircu-late liquid from the receptacle through the return pipe 46 to the always open portion of the supply line 18 for return to the tank.
  • thermocouple 54 connected by the conductor 56 to the displacement pump means to initiate operation thereof in response to the cold of the liquid present in the trough.
  • the pump 44 could be mounted -in asuitable area within the insulated space or it could be mounted a substantial distance from the cargo tank and the insulation surrounding the tank.
