Definitions

  • This invention relates to a ship and, more particularly, to a ship designed especially for transportation of a liquid cargo which needs to be maintained at a temperature substantially below zero.
  • the cargo In hauling liquefied natural gas or methane, hereinafter, for convenience, referred to as the cargo, some of the unusual factors which arise may be enumerated as follows:
  • the cargo should be maintained at substantially atmospheric pressure since the use of containers with walls strong enough to maintain the cargo under superatmospheric pressure of any substantial degree would so materially add to the dead weight of the ship as to make such construction economically unattractive.
  • Means'must be provided for preventing transfer of excessive amounts of heat from the surrounding sea and atmosphere to the cargo to prevent excessive vaporization thereof.
  • the hull of the ship should be thermally insulated from the cargo so that the latter will not cool the hull, especially when made of steel, otherwise the ship will be unsafe.
  • the tanks or the like means in which the cargo is contained should be capable of being hydrostatically tested before assembly into the ship in order toinsure that the tanks will be structurally sound. While the tanks or containers for the cargo should be effectively insulated to minimize the transfer ofi heat, means must be provided whereby access to such tanks can be had for rapid loading and unloading. Since the individual tanks for the cargo will be subjected to severe temperature changes during loading and unloading, their arrangement in the ship must be such that they are adequately supported to prevent damage during the voyage while permitting free movement of the tanks in expansion and contraction without subjecting the ships hull to substantial stresses due to the effects of the temperature changes or temperature graclients which might exist.
  • maximum utilization should be made of the hold space of the ship for the storage of the liquefied gas; means should be provided for maintaining separation between the cargo tanks and the ships hull, otherwise the liquefied gas might inadvertently come into contact with the ships hull to cause the deterioration or destruction thereof when, as is usual, the hull is formed of structural steel plate which loses its ductility at the temperature of the liquefied gas; means should be provided for ready and complete inspection of the walls of the tank and for instrumentation to detect changes in the wall temperatures and the like elements which would indicate either breakdown or failure of the insulation or of the liquid cargo tanks; means should also be provided for inspection of the components of the ship and cargo without interfering with the cargo space or the construction of the space, and it would be desirable to enable construction of the ships hull with lesser space taken up by reinforcement, thereby to make more space available for the cargo to be transported.
  • FIGURE 3 is a cross-sectional view in the crosswise 7 direction of a ship shown in FIGURE 1;
  • FIGURE 4 is a detailed sectional elevational view of the cross-section ofi the ship below the top deck and illustrating the construction of the ship and the hold space therein;
  • FIGURE 5 is a fragmentary sectional elevational view through -a bulkhead of the ship
  • FIGURE 6 is a side elevational view taken along the line 66 of FIGURE 5, and
  • FIGURE 7 is a sectional view taken along the line 7-7 of FIGURE 4.
  • the concepts of this invention are embodied in a ship 7 construction formed of an outer hull 20 having a bottom 22 and vertically disposed side walls 24 and 26 in combination with an inner hull 28 having both bottom and side walls which extend in closely spaced apart parallel relation with the corresponding walls of the outer hull throughout the major portion of the ships length which defines the hold space 30*.
  • the walls forming the outer hull are reinforced by frames or beams 32 which extend lengthwise along the inner surface of the outer hull in fairly closely spaced apart parallel relation and by web frames or girders 34 and 36 which extend crosswise of the bottom and vertically along the side Walls of the ship in closely spaced apart relation.
  • the inner and outer hulls are interconnected by stiffening and reinforcing members in the form of tie bars 36a which are secured at their outer edges to the inner face of the outerhull and at their inner. edges to the outer face of the inner hull, or to the frames fixed in the desired spaced relation to the adjacent surfaces of the hull members. It will be noted that the thickness of the walls of the outer hull and the dimensions of the beams and frames increase from the top to the bottom of the ship to compensate for the increased loads on the portion of the ship displacing water.
  • the space between the bulls is divided vertically into compartments or wing tanks by a series of vertically spaced apart platforms 38 secured, as are the plates or tie bars, to the inner and outer surfaces of the outer and inner hulls, respectively, or preferably to the frames, as by means of welding.
  • the platforms are provided with openings to enable free communication between the spaced compartments.
  • Openings 42 are provided in the web frames for ventilation, and access openings 44 still larger in dimension are provided in the web frames in the areas immediately above the platforms to enable a person to travel in a fore and aft direction-the space between the hulls being sufficient for the passage of a person therebetween.
  • the space between the hulls is divided laterally by a series of plates, hereinafter referred to as bulkheads 40, which extend upwardly substantially continuously from the bottom to the top of the side Walls to subdivide the space between the inner and outer hulls into a plurality of wing tanks.
  • the outer surface of the inner hull is similarly stiffened and reinforced with longitudinally extending frames or beams 46 and crosswise extending ribs.
  • the girders can be used to provide a means for attachment of the interconnecting plates or girders 34 and 36 and interconnecting tie bars 36a, thereby to effect a rigid and fully reinforced connection between the inner and outer hulls.
  • the ships hold can be divided lengthwise by a plurality of cofferdams which extend crosswise between the hulls.
  • cofferdams which extend crosswise between the hulls.
  • the described reinforcing and stiffening beams, girders and plates can also be embodied between the walls to enable access to the space between the walls and for subdivision of the space into communicating wing tanks.
  • the inner surface of the inner hull 28 is lined with a relatively thick layer 54 of an insulating material of low heat conductivity and preferably characterized by having a'structural strength capable of supporting loadto enable attachment to the walls of the inner hull and to enable the cargo tanks to be carried between insulation without direct attachment to the walls of the ship.
  • a relatively thick layer 54 of an insulating material of low heat conductivity preferably characterized by having a'structural strength capable of supporting loadto enable attachment to the walls of the inner hull and to enable the cargo tanks to be carried between insulation without direct attachment to the walls of the ship.
  • use can be made of panels of balsa wood or quippo, or use can be made of foamed glass or foamed plastics which are capable of standing up under the temperature conditions to which the plastic will be submitted in the presence of the cargo.
  • the cargo tanks 56 of large dimension are adapted to be arranged in side by side relation within the insulated hold space to'provide a cluster with means harnessing the tanks at the top and operatively engaging the tanks at the bottom to hold the tanks in a predetermined relation within the insulated hold while permitting free expansion and contraction movements in the lateral and vertical directions responsive to changes or variations in temperature which might take place.
  • the tanks are mounted relatively independently of the insulated hold space, but arranged and constructed substantially completely to fill the hold space.
  • the means for harnessing the cargo tanks is the subject matter of another application of Farrell, et al., Serial No. 634,571, filed January 16, 1957, now Patent No. 2,954,003, and entitled Means for Transportation of Low Temperature Liquids.
  • the means for lining the walls of the inner hull with panels of balsa wood is also the subject matter of a still further application of Dosker, Serial No.
  • the means of constructing the tanks preferably of prismatic shape is the subject matter of still a further application of Farrell, et al., Serial No. 634,547, filed January 16, 1957, now Patent No. 2,982,441, and entitled Liquid Storage Tank.
  • the means for mounting the tanks to enable expansion and contraction movements is generally described in the parent application to which reference has previously been made.
  • the construction wtih the inner and outer hulls arranged in closely spaced apart, substantially parallel relation enables the beams extending crosswise of the ship and the girders extending lengthwise of the ship to interconnect the hulls in a manner which enables the outer hull to incorporate the inner hull as a part of its reinforcement and support.
  • This enables increased rigidity and strength to be incorporated into the hull structure while making use of beams and girders of considerably lesser width than would otherwise be demanded.
  • a fiat and substantially continuous surface is provided throughout the cargo space of the hold onto which the relaitvely rigid layers of the substantially strong insulating material can be applied thermally to insulate the entire hold space in which the cargo tanks are to be arranged.
  • a structurally strong insulation such as balsa wood
  • the layer of insulation as a second line of defense to block penetration of the cold boiling liquefied gas through the insulation to the metal support, in the event of failure of the cargo tanks or in the event of spillage of the cargo, it is desirable to make use of the layer of insulation as a second line of defense to block penetration of the cold boiling liquefied gas through the insulation to the metal support, in the event of failure of the cargo tanks or in the event of spillage of the cargo, it is desirable to make
  • the continuous and fiat surface of the inner hull is ideal for receiving the insulation lining, thereby to make all of the space within the inner hull and between the cofferdams available as cargo space, thereby materially to increase the capacity of the ship and utilization of the ship as a liquid methane carrier.
  • the foregoing represents some of the more important technological advances capable of being derived from the combination of closely spaced apart inner and outer hulls, with the inner surface of the inner hull lined with a thick layer of thermal insulating material to provide an insulated hold space.
  • the double-walled construction can extend throughout the entire length of the ship, but the important area resides along the portion spaced inwardly a short distance from the bow and aft of the ship wherein the cargo space is located.
  • Insulated coiferdams extending crosswise of the ship can provide the desired separation and support for the insulation, and the unlined space in the bow and aft can be employed for housing the mechanism powering the ship and for the storage of other liquids and fuels or cargo which do not require the maintenance of low temperatures.
  • a large number of further advantages are available in a tanker construction embodying spaced inner and outer hulls with insulation lining the inner surface of the inner hull to provide an insulated hold space.
  • the spaced inner and outer hulls providing a sealing relation therebetween, enable utilization of the space as wing tanks wherein water or other fluid can be used as ballast in navigation of the ship.
  • the space can be divided by the bulkheads and the like into separate sections to provide separated wing tanks with individual pumping system for handling the fluid.
  • the wing tanks and the like non-cargo spaces can be used for the storage of liquid petroleum products which do not require refrigeration or maintenance at low temperature.
  • most efficient utilization can be made of the space between the walls to carry a liquid fuel or petroleum products which can be used as ballast and which can be circulated for temperature control and which can even be heated when necessary to conduct cold away from the walls.
  • the spaced relation between the inner and outer hulls enables one to enter the space for visual inspection of the outer walls of the inner hull for purposes of detecting deterioration in the construction in sufiicient time in advance to prevent failure which might otherwise lead to difficulties and even to the destruction of the ship. It simplifies replacement and repair of sections of the inner hull without tying up the ship in drydock or the like, and it provides space wherein additions can be made to shore up weaknesses which might develop in the construction to anticipate a dangerous situation which might otherwise develop.
  • the spaced relationship between the hulls enables instrumentation 160 of the ships hulls for automatically recording changes in conditions as would provide a warning sufficiently in advance of the development of a dangerous condition to enable protective measures to be taken.
  • instrumentation would record temperature changes resulting from the development of cold spots possibly caused by the failure of a cargo tank or portions of the insulation in particular areas. These are desirable from the standpoint of protection of the outer hull from refrigeration to a temperature where the steels might lose their ductility and strength.
  • the closely spaced apart relation between the inner and outer hulls and the subdivision of the space into wing tanks permits the control of temperature in the space between the walls to make certain that safe operating conditions are maintained.
  • the area between the hulls can be heated by means of steam coils and the like to maintain a desired temperature condition between the walls. This will prevent the transmission of cold to the outer hull and it will also operate to maintain the inner hull at a temperature sufficient to prevent loss of ductility and strength. It will also permit maintenance of the temperature of the inner hull at a uniform and desirable level for controlling heat loss through the insulation.
  • the space between the hulls can be used for the rapid circulation of water or other liquid or fluid over the adjacent surfaces of the hulls to conduct cold away from (i.e., furnish heat to) the walls and for controlling the temperature of the walls to maintain safe and controlled operating conditions.
  • each of the bulkheads subdividing the cargo space comprises a pair of walls in closely spaced apart parallel relation.
