Definitions

  • the present invention relates to a normally submerged hose which can be floated on the sea, if necessary, for transportingoil and other liquids, mainlyfor loading or landing such liquids to and from a ship and a storage station.
  • the principal object of the invention is to obviate the heretofore usually unavoidable troubles caused in loading or landing a large quantity of oil and other liquids from a ship to the storage tank on the wharf or vice versa and to facilitate easy operation and control of such hose for transporting an extraordinary large quantity of oil and other liqiuds.
  • the hose is usually kept floating on the surface of the sea by means of a suitable floater and the like means.
  • the hose for transportation is usually submerged and fixed to the bottom of the sea.
  • the object of the invention is to obviate the above disadvantages.
  • the invention is characterized in 3. normally submerged hose which can be floated, if necessary, on the surface of the sea for use and when the loading or landing of oil has completed it is submerged to the bottom of the sea. It has advantage that it can be easily shifted as desired between the detached storage stations.
  • FIG. 1 is a cross sectional view of a hose embodying the invention
  • FIG. 2 is a side view partly in section of the hose embodying the invention showing the construction of the joint portion
  • FIG. 3 is a side view similar to FIG. 2 illustrating a modification of the joint portion
  • FIG. 4 is a diagrammatic view showing the condition when the hose of the invention is used.
  • the hose embodying the invention consists of two concentric hoses, a central hose'l of which is used for transporting oil or other liquids and the outer hose 2 serves, together with hose 1, as the floating mem her.
  • the hose is made of rubber reinforced with fibers or Wires, so as to be flexible or deformable and particularly the inner hose for enabling to transport oil and other liquids
  • the outer hose 2 constituting the floater is made of materials having good weather proof and sea-water proof characteristics, high strength and also being fleXible and deformable in case of using air for floating.
  • the interspace 3 between two hoses 1 and 2 is used to receive air or water for floating or submerging the hose.
  • a special metallic joint as shown in FIG. 2 is used or the hose is made of a special construction as shown in FIG. 3.
  • the metallic joint of special construction shown in FIG. 2 consists of a flange 4 having double sleeves 5 and 6, of which the sleeve 5 is to be connected to the floater 2 of the hose, whilst the sleeve 6 is to be connected to the hose member 1 for oil transportation.
  • An opening 3' serves for introducing or discharging air or water into the space 3 by means of a pump (not shown) and 4' represents a bolt hole for connecting the flange with each other.
  • a metallic flange joint 4 having an ordinary single sleeve 6 is connected to the inner hose 1.
  • a pipe 7 is provided for feeding in or sucking out the air into or out of the space 3 by a pump (not shown) or similarly the air in the space 3 may be replaced with water for submerging the hose.
  • the pipes 7 may be connected with each other or to a necessary pipe by means of a joint piece 8.
  • the pipe can be so designed that when the space 3 between the inner and outer hoses 1 and 2 is filled with air the hose can be kept floating on the sea surface during transportation of oil, whilst if the air in the space 3 is replaced with water the hose can be submerged underneath the sea level and it can be kept at a desired depth into the sea by adjusting the quantity of water to be replaced with air or the amount of air to be sucked out of the space 3 by means of a pump.
  • the hose of the invention brings useful effects in the transportation of oil and other liquids.
  • FIG. 4 A manner of using the hose of the invention is shown in FIG. 4 as an example, in which A shows the hose floating on the sea.
  • A shows the hose floating on the sea.
  • the air in the space 3 is sucked out or replaced with water, then the hose is submerged underneath the sea level as shown at B.
  • air is delivered into the space 3 or the water in the space 3 is replaced with air.
  • the outer hose i.e., the floater 2 should be made sufliciently flexible to be deformable as shown for example by the dot and dash lines 2 in FIG. 1 illustrating the case when the air in the space 3 is sufliciently sucked out.
  • the oil in the inner hose 1 is forced out to a storage tank by means of water from city main or by sea water through a pump.
  • A represents the floater with hose in floating condition
  • B shows the hose and floater when submerged.
  • a buoy 9 or float chamber contains a pump with the necessary controlling valves and other devices installed. It may have suflicient space for an operator for the necessary operation of replacing air and water or controlling the supply or suction of air.
  • a method of conveying oil or other liquid over an expanse of water with the aid of a hose pipe consisting of at least two substantially coaxial tubes assembled to provide an interspace between them which method comprises, when the liquid is to be conveyed, filling the interspace with a gaseous medium so as to cause the hose to float and then passing the liquid through the inner pipe, and when conveyance of the liquid is no longer needed,
