Definitions

  • the present invention relates to a container of the kind for containing very cold liquids and comprising a tank (l, 15) of cold resistant material surrounded by thermal insulation (2, 14) characterized by the provision of a thin substan- [54] ZE? IgiQUEFIED GASES tially water-impermeable film or foil extending parallel, or 8 claims raw 8 generally so, to the exterior surfaces of the sidewalls and, op- [52] U.S. Cl 114/74, tionally, the bottom of the tank and located within the 220/15 thickness of the surrounding thermal insulation adjacent the [51] Int. Cl. B63b 25/16, external face thereof, i.e.
  • This invention relates to containers used for the storage and transport of very cold liquids and of the kind comprising a tank of cold resistant material surrounded by thermal insulation.
  • the invention is primarily intended for containers of the kind defined above for liquefied gases at near-atmospheric pressure and low temperature.
  • Containers of the kind defined above are of two distinct types.
  • the container comprises a self-supporting tank, that is to say one having sufficient structural strength to hold the liquid within the tank and withstand the hydrostatic pressures and any inertia forces, without depending upon any other means outside the tank for aid in supporting the walls of the tank against buckling.
  • the tank is of a material, e.g.metal, which is cold resistant, Le. which is not subject to cold embrittlement at the temperature met in use, for example, the temperature of liquefied gas.
  • the tank is enclosed by an external housing of thermal insulation, which either directly encases the tank or lines an outer shell, so as to define a containing space within which the tank is located, with or without a gap between its exterior surface and the interior surface of the insulation.
  • the other type of container is know as an integrated container and comprises a housing of solid load-bearing thermal insulation lined with a thin and flexible fluid-tight membrane tank of sheet material, e.g. metal, which is not subject to cold embrittlement at the temperature which will be encountered in use and which is not self-supporting, but is supported, against internal loads due to hydrostatic pressures of contained fluid and any inertia forces, by the surrounding solid insulation.
  • the insulation lines and is itself supported by, a substantially rigid supporting shellso that the insulation directly transmits to the supporting shell all the pressure exerted by the contained fluid upon the walls of the membrane tank.
  • Containers of both of these types are intended to be used, either for storage on land or for transport, for example, in tanker ships for the overwater transportation of very cold liquids such as liquefied gases.
  • tanker ships usually have a double hull and the inner hull is divided by transverse bulkheads so as to divide the hull into individual cargo holds in which the containers of either type are located.
  • the space between the hulls, and possibly also the spaces between adjoining transverse bulkheads, is or are divided into tanks to contain water.
  • Such water is provided for two purposes. One purpose is to serve as ballast for trimming and safe operation of the tanker ship.
  • ballast water may be provided in at least some of the ballast tanks even when the cargo tanks are full of liquid cargo.
  • the ballast tank adjacent the affected part of the insulation can be filled with water thus preventing the steel of the inner hull from being cooled below the safe level.
  • a problem encountered in the use of containers of the kind concerned in tanker ships is that, should aleak develop in a wall of a ballast tank at the side adjacent the cargo tank, then water will penetrate into the insulation which will usually be partially water permeable, and will tend to flow towards the tank.
  • a thermal gradient across the thickness of the insulation when the tank contains cold cargo and water penetrating the insulation towards the tank will progressively become colder and when it arrives at a location below the freezing point of water it will freeze. Accordingly, ice will build up within the outer thickness of the insulation.
  • the aim of the present invention is to overcome these problems and provide, for very cold liquids, a container of the kind defined and of either type specified above, in which the formation of ice within the thermal insulation is prevented or considerably reduced.
  • a thin substantially water-impermeable film or foil extending parallel or generally so, to the exterior surface of the sidewalls of the tank and located within the thickness of the insulation adjacent but spaced a short distance inwardly from the external face thereof, i.e. the face remote from the tank.
  • the substantially water-impermeable film will prevent any significant quantity of water or water vapour, which has penetrated the outer thickness of the insulation, from further penetrating the insulation.
  • the film or foil will be at a temperature above the freezing point of water so that the water will not freeze but will run down the outer face of the film through the outer thickness of the insulation and collect adjacent the bottom of the tank.
  • the film or foil will be located at such a position within the thickness of the insulation that under normal conditions with the container loaded with a very cold liquid the film or foil will .be at a temperature a little above the freezing point of water.
  • the film or foil may be of any of various materials. Thus, it may be a film of a suitable plastics material. As examples may be mentioned polyethylene, polypropylene, polyvinylchloride and nylon andthe plastics films marketed under the registered trade marks Mylar, Neoprene, Teflon" and Melinex".
  • the film or foil could also be constituted by a metal foil, such for example'as aluminum, copper or stainless steel, although where the container is to be used in a tanker ship the foil would probably require to be coated, on at least that face which will be contacted by sea water (since the water used in ballast tanks is usually sea water), with a material protecting the foil from corrosion by any impurities in the sea water.
  • the film or foil could, in fact, be constituted by a laminate of a metal foil and a plastics film, or by a plastics film provided on one face with a metalised foil. Examples of the latter are aluminized Mylar" and copper polyester. Moreover, the film or foil could be constituted by a woven fabric of either natural fibre such as rayon, or manmade fibre such as Terylene which is plasticized, rubberized or otherwise treated to render it substantially water impermeable. The film or foil might even be constituted by one of the commercially available waterproof papers. These are examples only of many materials which could be employed as, and which meet the requirements of, the film for foil.
  • the film or foil must have adequate tensile strength, tear resistance and be substantially impermeable to'water, i.e.have an extremely low permeability to water.
  • the degree of water impermeability which is required and which is meant by the phrase substantially water impermeable may vary depending upon the use and location of the container but should in most applications preferably have a permeability of less than 10- kg./m.2/sec.
  • the film or foil must be of a thickness to provide the requisite tensile strength, tear resistance and be substantially water impermeable.
  • the film or foil should not be less than onethousandth of an inch or 0.025 of a millimetre in thickness and preferably should be of the order of five-thousandths of an inch or 0.125 of a millimetre in thickness.
  • the arrangement is such that the water is collected adjacent the bottom of the tank; that is to say, a water impermeable receptacle may be provided below the bottom of the tank.
  • This receptacle may be in the form of a tray into which the lower ends of the film or foil associated with the sidewalls of the tank extend.
  • This receptacle could be constituted by a portion of film or foil but is preferably of somewhat thicker material.
  • a pump or equivalent means is provided for removing the water which collects in the receptacle.
  • the bottom of the cargo hold may constitute the watercnllectlng tray or may he formed or provided with a receptacle or sump.
  • the water collecting in the cargo hold is preferably removed, either by being allowed to flow through a hole connecting the sump with the space between the inner and outer hulls perhaps controlled by a nonreturn valve, or through pipes and an associated pump located within the space between the inner and outer hulls.
  • a water impervious barrier will preferably also be provided for preventing water from travelling up through the insulation below the bottom of the tank under the action of the pressure head of water.
  • This barrier will advantageously be constituted by film or foil arranged in the same relation to the bottom of the tank as the film or foil is arranged in relation to the sidewalls of the tank, that is, substantially parallel to the bottom adjacent the lower or outer face of the insulation and preventing any water which has penetrated the lower or outer thickness of the bottom insulation from further penetrating the bottom insulation.
  • the outer thickness of the thermal insulation exterior of the film or foil must be very permeable to water to enable the water to penetrate this thickness of the insulation and to enable the water to run down the outer face of the film or foil.
  • Suitable water-permeable thermal insulations are glass fiber, wool, mineral wool or rock wool.
  • the thermal insulation can be of one material or one combination of materials only, that is to say the portions at both sides of the film or foil can be of identical material or combination of materials. Alternatively, the insulation at opposite sides of the film or foil may be of different materials or combinations.
  • the inner layer of insulation between the tank and the film or foil may be relatively thick, whereas the outer layer of thermal insulation, exterior of the film or foil may be relatively thin.
  • the film or foil may be in the form of a continuous membrane forming a continuous substantially water-impermeable wall surrounding at least the sidewalls ofthe tank.
  • the film or foil may be in sections which are sealingly engaged with other substantially water-impermeable parts so that the whole constitutes a water-impermeable barrier.
  • mount thermal insulation for a container of the kind concerned and in the form of blocks or pads for example within the hold of a ship, by securing the pads to spaced securing strips of water-impermeable material which are secured to the inner hull.
  • thermal insulation could be provided between the adjacent strips and incorporate a thin section of film or foil dimensioned to fill the space between the strips and sealingly secured to the strips so that all the sections together will the strips form a continuous waterimpermeable barrier.
  • the horizontal strips are preferably formed with vertical slots or apertures enabling water running down the film or foil to pass therethrough and into the collecting receptacle adjacent the bottom of the tank.

  • This receptacle is of a material which is not subject to cold embrittlement and is intended to collect any of the very cold fluid cargo escaping from the tank as a result of a minor leak in the latter. This escaping fluid will be collected in the receptacle and will be removed therefrom through pipes 5 by means of a pump 6.
