Definitions

  • the hull for transporting, on a body of water, cargo consisting of barges, pontoons, and lighters, and other floating cargoes.
  • the hull has a bow, a stern, and water-tight buoyancy compartments in side walls.
  • the hull also has a perforate bottom shell with rigid supporting and reinforcing structure, enabling the cargo hold to be flooded and open to the sea under all conditions while loading, in transit, and during discharge.
  • a hinged gate is provided at either or both ends of the hull for rapid flotation loading and unloading of the floating cargo, and each gate closed during transportation of the cargo.
  • the vessel carries means for moving the cargo into, out of, and within the hold.
  • a series of vertical pistons secure the floating cargo units by exerting a downward force to bring the cargo to bear on the hull structure.
  • the water in the hold having communication with the sea, provides buoyancy for the cargoes secured therein.
  • This buoyancy supports most of the deadweight of floating cargoes, so that typically only a minor portion of the deadweight is carried by the vessel.

  • FIG 9 U.S. Patent 0ct.21, 1975 Sheet5of 12 3,913,512
  • This invention relates to vessels for transporting cargo, and it particularly relates to improvements'in vessels in which the buoyancy of the cargois utilized to support a substantial portion of its own weight, leaving the remaining, typically minor portion to be carried by the hull.
  • the hull serves to contain the cargosecurely and'at the same time to provide a smooth external envelope of adesired 'form to minimize hydrodynamic resistance; at thesame time, the hull enables employment of buoyancy of the cargo by always maintaining water within the hold comrrion with the sea, by means of permanent openings in the'bottom of the hull for free passage of water in and out.
  • the vessels of this invention may have their floating cargo loaded and unloaded into the hold by cranes, but in many instances the vessels are preferably loaded and unloaded through a gate'at either or both ends.
  • vessels may also carry deck cargoes which are supported by the buoyancy of the vessel and excess buoyancy of any floating cargo carried.
  • the invention isfparticularly helpful in transporting cargo of the type that is shipped in barges or floating containers.
  • a series of these barges or containers istypically moved on water by a tugboat up to a location adjacent the bow or stern of thevessel; then the series of barges or containers is loaded in through a gate in the bow or the stern. After the voyage, thesame series of containers is unloaded through a gate in the bow or stem and towed away by a tugboat.
  • the present invention shares in common with US. Pat. No. 3,356,058 to Lunde the employment of buoyancy forces through the use of a pefforate hull and side walls of the vessel.
  • the presentinvention calls for securing means which hold floating containeriied cargo units, such as barges or lighters, in a positively fixed position during transport, so that the bottoms of all of the units are in firm engagement with the hull, and holding devices secured to the frame of the vessel and spaced above the hull extend down from the deck level to engage the tops of the units.

  • the stern gate 81 when used, is closed when the vessel 10a or 10b is transporting its cargo, being raised only for loading or unloading. 1
  • one gate may be.used for loading and the other for unloading, thereby achieving a firstin, first-out operation of floating cargo units.
  • a principal cargo for the vessel preferably comprises a series of containers 16, such as standardized covered lighters or barges, each of which isa standardmember and each of which is outfitted with standard equipment. All the containers 16 are contemplated to be substantially identical in size and shape, and each has certain fittings, as shown in some of the drawings such as in FIGS. 9 and 10, which may include cylindrical projections 25 at their upper ends 24 with frustoconical terminal projections 26 extending above the projections 25.They also preferably have cy-. lindrical recesses 27 at their bottoms 28 with frustoconical terminal sockets 29.

  • Tugboats3l push or pull the. trains. Normally, due to various degrees of loading and various cargo densities, the containers 16 will not all float at the same level. In order that they float at the same draft or water level, they would all have to be either empty or all loaded with exactly the same amount and density of cargo. So a randomprobability of drafts would be as shown in FIGS.
  • the vessel l0 is designedto accommodate such differences, so that during barge handling operations there is suff cientspace 32 between the bottom transverse hull girders l4 and the deck transverse girders 33, and that space is substantially twice that of the height-of the containers 16.
  • the bow gate 23 When the containers 16 are towed or pushed up to the vessel l0, the bow gate 23 is opened so that the containers can be floated into the vessel, and when the containers 16 approach the vessel 10 closely, a pair of winches 35 on the ship 10 are attached by cables 36 to the foremost of the containers 16.

  • the total load of the vessel 10 is lightened by the lighter containers 16, which may be completely empty or may be considerably lighter and thereby, in effect, impart a negative load to the hull 11, counteracting to some extent the positive load of the filled and heavy barges or lighters 16. This transfer of buoyancy enables a sharing which is very effective.
  • Unloading operations may proceed as shown in FIG. 3, by opening the bow gate 22 and with the winch 35 then being attached over the forward pulley 38 and then to the aforemost container 16, and then the containers are pulled out through the bow in order, still locked to gether. .Then the unloaded series of barges or lighters 16 may be push or pulltowed by a suitable tugboat 31 to cargo distribution points.
