Description

[Detailed description of the invention] Barge transport vessels and barge loading methods This invention was developed as a preparation for transporting a cargo carrier capable of transport by water by a cargo carrier. Regarding the method of loading a cargo carrier onto a cargo transport vessel, this method includes The steps include filling the containment area with water and refloating the cargo carrier at the location. . The invention also relates to a cargo transport vessel having facilities for loading by such a method. Regarding.

In recent years, as a result of searching for ways to make cargo transport more economical, sea transport ships have been developed. This led to the introduction of equipment for loading multiple cargo barges into the design. like that The transportation system has many advantages, including transporting inland cargo to ocean-going ships via inland waters. Transshipment operations via roads and final transportation of cargo to coast or inland unloading points The advantage of being able to simplify the work involved is worthy of public attention. Loading cargo from a barge onto a transport ship Significant effort and energy is saved by eliminating facelift work and vice versa. Not only will costs be saved, but the speed and general convenience of water transport operations will also be improved. be promoted.

In the known type of barge loading system, the cargo loading barge is located at the stern of the cargo transport vessel. After being pulled from the water surface by the installed lifting machine, it is transported to the cargo deck by a conveyor. (e.g., September 1972 issue [ShippingWorldcl. ana 5hip - builder J Title J on page 1045 Doc (see chapter on Tor Lykes J).

Furthermore, in recent years, cargo transport ships have been built that utilize the so-called floating cargo loading principle. . These ships have a stern section to allow for direct lifting of floating cargo. It has a self-sinking ability that allows it to fill the cargo loading area with water (19 November 1980 issue “Mak Topplaterne Diesel Engine Container-only cargo ship “0ondock J” listed on page 57 of Journal J (see chapter).

Cargo can be brought into the ship while floating, eliminating the need for expensive lifting machinery. It disappears. After pulling the barge onto the transport vessel, the barge is ballasted so that the transport vessel can surface. The cargo loading area is completely drained. At that time, the barge was a transport ship. Inside, it is placed in a state similar to an acid dock.

The number of barges of a given size that can be docked in this way on a transport ship depends on the length of the cargo loading area. It depends on the height and width. The extent to which this dimension can be increased in transport ship design varies. Although constrained by factors, those factors include of course the acceptability of the transport ship itself. Includes maximum length and width.

To increase the number of barges that can be loaded, make the transport ship double-deck. Both the lower deck as well as the upper deck are equipped with the necessary equipment to dock the barge. Proposals have been made to allow ships to sink to the waterline. Furthermore, to the specified water level inside the ship. A floating barge can be lifted inside the ship and suspended from the deck above. By equipping the transport vessel with a hydraulic inboard submersible lift such as A method of storing data in several stacked stages has also been proposed. And then the barge to the lower level. can be stored. According to this proposal, there is a need for a second deck and an upper deck for the barge. This avoids the need for increased docking water for transport ships to be loaded. Each of the above propositions Both proposals are published in the June 1974 issue of "Shipping, World and 5. hipbuilder J, pages 599-602.

This invention provides a method for transporting a small cargo carrier by a transport ship using the floating loading principle. However, according to this method, there is no difference between the cargo carrying capacity of the transport vessel and its main dimensions. can establish a favorable relationship.

The method according to the invention is defined in claim 1 below. This method is The cargo can be directly submerged in the water without being contaminated by water entering or exiting the cargo carrier. the use of closed cargo carriers that can be erected; Directly to each storage position in the cargo loading area of the transport vessel to keep the cargo carrier upright. It is characterized by the fact that it can be pulled in while standing.

An important advantage of this method is that the main dimensional characteristics of the transport vessel are comparable to those of previously known methods. Therefore, it can carry far more cargo carriers than the number of ships that can carry it.

Loaded cargo carriers may be stored in a close-contact configuration in several adjacent rows parallel to each other. I can do it.

Since the cargo carrier is loaded with cargo, it must be moved from its normal horizontal floating position to its upright position. The energy required to fall into the state is not excessive. necessary for that This force can be obtained from a dynamic crab knit whose operating output is not very large.

Transport vessel - The above-mentioned owner of a cargo carrier used for loading and unloading cargo. Because of its essential functions, it is often used as a convenient term to refer to cargo carriers. The name "Shike" is used. However, this cargo carrier is different from any conventional barge. It should be understood that there is no need for it to have any atomic form. Cargo carriers are always long. can have any desired longitudinal and transverse contours . For example, the carrier may have a substantially cylindrical or rectangular cross section over substantially its entire length. It can also be a surface. The carrier must be of durable construction. do not have. The carrier may be used only once or used only a few times and then disposed of. It can also be a relatively inexpensive container intended for storage.

To avoid unnecessary waste of storage space on the transport vessel, the length of each barge should preferably be the same. be of a length that occupies most of the height of the storage area of the transport ship when in the upright position. is desirable. The length of the barge should preferably be at least 215 cm above the height of the storage area. However, it is most desirable to set it to 6/4 or more if possible.

The extent to which the behavioral benefits of the present invention are realized depends, of course, on the storage density of the barge. It is a theory. A good procedure is to install uprights placed in each of a number of storage rows in the storage area. The goal is to maintain as many barges as possible. All cargo storage areas on a transport ship are Of course, it is possible to divide the storage area into many smaller storage locations, but in this case as well, A large number of barges can be stored in each divided storage location.

Each barge shall have one or more loading/unloading operations preferably confined to its ends. ...It is desirable to have a hatch, but the hatch should remain above the waterline even when the barge is upright. It must be in a position where it remains exposed. have a no-tsuchi limited to one end The barge is tilted, for example, on its ramp at the quay for loading cargo onto the barge. Transferring liquid cargo by introducing it onto the barge while it is supported It can be loaded if necessary.

If cargo loading is limited to one end of the barge as described above, then Effective water-tight sealing of the tube is not a critical issue. but water Hermetic sealing is desirable in all cases for barges. transport ship carrying a large number of sealed barges introduces an important safety element to transport vessel operations. Enter. Sealed barges do not allow the hull of the transport vessel to flood into the barge loading area. Provides buoyancy to help the transport vessel stay afloat in the event of severe damage .

Such damage to the transport vessel may also occur if the cargo or any part of the cargo is contaminated with oil or other contamination. Unrecoverable loss of cargo, even if it is contaminated with oil or other contaminants. It is safe to assume that there is almost no possibility that this will lead to seawater pollution.

This method is particularly suitable for liquid materials, which may still be bulk solid materials such as coal. This is particularly advantageous for transporting highly fluid cargoes.

Cargo loading space inside the barge should be The cargo space should be loaded so that the space is substantially completely filled with fluid cargo.

If it is desirable to use a barge with one or more internal cavities, Although often present, such voids can reduce the available cargo loading space of the barge. However, the void may be filled with water or other material of similar or higher specific gravity. Can be filled substantially completely. Such voids can be removed into the barge. limited by tanks or capsules that are functionally fixed and/or variable in size. can be determined. The position of the open space within the barge is determined by the position required to erect the barge. Does not significantly increase energy or destabilize the barge in upright buoyancy We must decide not to do so.

In carrying out the invention, barge uprighting operations may be carried out within the transport vessel or on the barge. This is carried out while the casualty transport ship is docked.

The depth of water required for the cargo entrance to the transport vessel is This is a matter of choice for the design of the transport ship. This provides more flexibility. Moreover, the work of uprighting the barge is carried out by a machine equipped on the transport ship. This can be conveniently implemented depending on the structure. However, in the vicinity of transport ships, Barge uprighting operations carried out on its exterior are within the scope of the invention.

In some embodiments of the method according to the invention, the uprighting of the barge is carried out by a transport vessel. carried out with the aid of or by a force applied to the barge from an upright mechanism be done.

As an alternative to or use of a mechanism that exerts an external uprighting force on the barge As a supplement to this, the buoyancy that causes or assists in upright movement is explained below. can be created by draining a buoyant tank.

After the barges are placed in their respective storage positions on board the transport vessel, the barge storage areas are The water supporting the barge is completely or partially drained from the transport vessel. this thing is not essential. Depending on the dimensions of the transport vessel and its cargo carrying capacity, the barge The weight of the supporting water may be extremely small compared to the total cargo carrying capacity of the transport vessel. do not have.

The invention includes a construction for loading cargo carriers by the method described above. Includes constructed and equipped cargo transport ships.

A cargo transport ship according to the present invention is defined in claim 8 below. This transport ship is a long form of cargo conveyance that is placed in an upright position in each storage position of the above-mentioned loading area. It is characterized by having means for holding the ship.

Such a cargo carrier may enter a floating cargo carrier in a horizontal position in a known manner. Transport vessels of comparable dimensions and proportions designed for docking may transport It is possible to transport substantially more cargo carriers than the number of ships.

It is desirable that a number of parallel storage lines be placed in the above loading area. .

As part of the equipment of the transport vessel to transport the upright cargo carrier to each storage position. It is desirable that conveyance means be provided.

In a preferred embodiment, the transport vessel itself carries each cargo carrier underwater at its loading location. and is provided with means for activating or assisting in the upright position. . Such uprighting means may be actuated by any of the methods previously described. can. Preferably, the uprighting means are adapted to apply an external uprighting force to the cargo carrier. It is preferable that the mechanism is or includes a mechanism that operates in the same manner as described above. So For example, the mechanism of the It applies an upward or downward force to one end of each cargo carrier. That's it As an alternative to, or a supplement to, the upright means, as previously described, the barge It may also be equipped with a means of supplying pressurized gas to drain the buoyant tank. .

Conveniently, transport ships are of closed type, with cargo loading areas located on one side of the ship. A cargo hold having at least one cargo entry door or hatch.

A transport ship has a number of holds, preferably separated by transverse watertight bulkheads. However, each hold should be equipped with means for uprighting the barge and means for barge transport and emplacement. be done. All other things being equal, the entire hold area of a transport ship can be divided into a number of locations separated from each other. Separation into holds is valuable from a safety point of view.

Particularly recommended transport ship designs are listed below, with examples being explained in detail below. It has each of the features defined in claim 16. By its design with very convenient barge handling means and high barge storage means by density are provided.

This invention includes a cargo transport ship combined with a large number of small cargo carriers as specified above. each cargo carrier shall be able to float at each storage location of the transport vessel. and stand upright in each storage area without contaminating the cargo with water flowing in and out of it. and that it remains upright and held in place by the retaining means described above. It is designed to be able to do both. Each cargo carrier is such a ship. It also has as its advantage any of the other features described above.

FIG. 11 is a schematic diagram of the barge uprighting mechanism.

The transport ship shown in Figures 1 to 6 has the following features: This transport ship (see Figure 1) It has six cargo holds 1 to 6 separated by transverse bulkheads 7 to 11. . Each of these holds covers the entire internal width of the ship between each side parast tank on the port and starboard sides. extending across and over the entire vertical distance between the bottom structure and the deck structure of the ship It is extending.

Referring to FIGS. 2 to 4, which are cross-sectional views of the cargo hold 5, this cargo hold has bulkheads 8, 9, By each ballast tank 12, 13 on the left and right sides, the bottom structure 14 and the deck structure 15 You can see that it is limited. This hold has 1 loading port and 1 loading port on the starboard side. 6°17, but the position of each hatch is shown in Figure 1 near the forward end of the hold. [Sθa Going W, L, J is on the water line during navigation.

Each of these hatches is provided with a respective watertight door 18, 19 attached to the hull. other Each of the holds 1, 2, and 4 to 6 is similar to the hold 3.

This transport vessel is equipped with multiple ballast water pumps to pump water into each ballast tank. However, it also has multiple pumps to pump water into each hold. Each of these All pumping devices are used in the same way as those normally used on oil tankers. Therefore, detailed explanation is not necessary.

In preparation for loading the barge, select "Loading W" in Figure 3.

Locate the appropriate loading water line between the upper and lower boundaries of each port and starboard loading hatch marked “L”. Each ballast tank should be loaded with each ballast tank in order to deepen the swamp of the transport ship - or several ships. At the same time, each hold is filled to the corresponding level. Watered. The doors of one or both loading hatches in each hold to be loaded are then sealed. It will be opened so that multiple barges can be pulled in while floating.

Inside each hold 1 to 6, each barge that was pulled into the hold while floating is placed upright. barge handling equipment for moving each upright barge to a storage position after support each barge in its storage position during the period that it is loaded onto the transport vessel. Equipped with means of holding. If a large number of holds should be loaded with barges. Then, each hold can be loaded at the same time, so it takes a relatively short time. Able to complete all complete loading operations.

When all the barges to be transported are placed in their respective storage positions on the ship, During the voyage, the ballast water inside the ship is drained to make it shallow to the waterline, and each hatch is All doors are closed and preparations for sailing are completed.

After the barge has been loaded into the cargo hold, if necessary, the water in the hold can be pumped into the cargo hold. It can be drained by pump. If this water or a sufficient portion of it enters the pump Thus, when drained, each upright barge in its hold will be in its respective stowage position. On each lower support pad 2° (FIGS. 3 and 4) located on the bottom structure 14 of the transport vessel Descend until seated.

All barge handling and storage facilities in each of the different holds are the same. Described below The following description relates to figures 2 to 6 showing the handling and storage of each barge in the hold 3.

Upon entry into the hold, each barge is elongated across the hold in the area between each loading hatch. lie down That area will henceforth be referred to as the ``float area''. Figures 2 and 3 The barge B1, indicated by the dashed line, is in a lateral position. This barge is Hatsuchi End loading/unloading halves sealed liquid-tight by covers H (Figs. 2 and 5) Has Tsuchi. The barge is both erected and floated in the onboard flotation area. The upright barge is located in a line of eight parallel storage lines extending along the length of the transport ship. Or be moved to another line. In Fig. 3, the barge B1 indicated by a solid line is It is fixed at one storage position within one line of the line. Figure 4 shows the ladder placed in the storage position. A horizontal line of eight barges is shown, including barge B1.

A plurality of rails 21 ( 2 and 6) is fixed to the underside of the bottom of the deck structure 15. wheeled trolley 22 (Fig. 6) is an electric motor mounted in the housing near both ends of this track. A traction means (not shown) consisting of a cable wrapped around the can be displaced. Each rail 21 and each wheel of the trolley 22 are equipped with racks and pins, if necessary. It can also be in the form of a nion. A plurality of carts 22 support short parallel rails 24. The green onion stand rod 23 is attached. These tracks consist of two cable pulleys aligned with each other. 26 and 27 on a transport vehicle 25 that rotatably supports the electric pulley drive motor 28. It forms a section of the trajectory for the opposite direction. Each pulley floats each barge to the onboard flotation area in the hold. wires each having a free end that is attached to the front end of each barge during or after floating; It carries cables 29.30. of the barge by winding each cable. The front end is lifted from the hold waterline and at a certain point during its tilting The rear end of the barge submerged in the water and began to slowly rotate downwards, but eventually the barge reaches a vertically upright position. Then its lifting force is released and the barge It remains levitated.

The effect of buoyancy (even if its magnitude is reduced) still remains during upright work. Therefore, cranes 26 to 28 can carry all of the barge's carrying capacity at any given time. There is no need to bear the burden. Maximum load force barge upright on crane The force required to start and the time required until gravity brings the barge to its vertical submerged floating position. The force required to compensate for the buoyancy force that decreases over time. After that, clay supports the floating barge in its upright position and moves the barge to its stowed position. This is to overcome the traction force that resists the movement of an upright barge through the water when That's it. Therefore, the crane can have a relatively small load-bearing capacity. Wear.

A buffer means 31 at one end of the inboard flotation area where each barge completes its rotation to its vertical position. (Fig. 2) is conveniently arranged.

Such a damping means shall be located on one side of the hold as indicated by symbol 31 in Figure 2. installed or projecting into the inboard flotation area from an adjacent transverse bulkhead. It doesn't matter.

Once the loading barge is erected as described above, it will rise upright while floating. move the loaded barge to a position that aligns with the specific storage line where the barge is to be stored. Instead, the transport vehicle 25 is displaced along each lateral rail 21.

The corresponding eight longitudinal tracks are arranged along the top of each of the eight longitudinal containment lines. Vehicle tracks 32, 33, 54. ..., 39 (Fig. 6°) are all symbol 4 0 (see Figure 6), suspended from the deck structure 15 by a number of suspension rods as shown in Figure 6. It is formed by a curved rail. The crane carrying trolley 22 is attached to each track for a crane transport vehicle. The strips 24 are aligned with the longitudinal rails forming the trajectory of the selected longitudinal storage line. In order to move along the lateral track rails 21 (see Figure 6) .

When the crane carrier 22 is stopped opposite the selected longitudinal storage line, Z’rc to prevent rocking of upright barge, ship facing Meso’s longitudinal containment line The inner flotation area is provided with a plurality of restraining engagement means, such means being selective displacement from a retracted position within or in close proximity to a directional bulkhead to an activated position; Can be done. An upright barge that is displaced along an inboard flotation area is such means and when displaced to the correct transport position along the longitudinal storage line It is engaged and restrained. Typical locations of such restraint engagement means are noted in FIG. This is the position indicated by No. 41. Such restraint engagement means may be used, for example, on multi-stage cargo ships. the respective supports for each vertically spaced stack are actuated in turn at the may be actuated by any known hydraulic or mechanical mechanism, such as those used to I can do it.

Instead of attaching two lifting cables 29.30 to each barge, one crane Run the cables to the four connection points on the barge at the four corners of the front or rear end of the barge. Can be connected with a stick. This installation method first allows the barge to stand upright. to assist in stabilizing the upright barge during storage operations and subsequent stowage operations. Reduces the tendency of the barge to rock.

Overhead longitudinal traction means (not shown) associated with each containment line track are installed at both ends of the hold. It has a traction cable driven by an electric winch located on the ground. clay The transport vehicle 25 is moved to a position consistent with the trajectory of the selected storage line as previously described. After being moved, this vehicle is coupled to the longitudinal traction means associated with it and The suspended barge is then moved along its storage line to its storage position. is propelled along the trajectory of the storage line.

Each storage line consists of a pair of upper and lower parallel curtains as shown by symbols 42.43 (Figures 3-5). Defined by the inner track. Each upper guide rail 420 position is above the loading water line. However, the position of each lower guide rail 43 is below the loading water line, and the water line is also below the ship. The location is close to the bottom of the warehouse. Single top guide between each adjacent barge storage line A rail structure and a single lower rail structure can be arranged, each of which has two Common to book storage lines. The upper guide rail structure and, if necessary, the lower guide rail structure are also marked with symbols. A guide rail such as the one shown at 44 can be installed, but this rail One line still allows workers to approach individual barge locations along multiple containment lines. It is used as a narrow passageway. One set of upper and lower edges placed on the side of each storage line. The spacers 45, 46 are each supported by the guide rails. Along the storage line each spacer in a different position than the other, so that the barge can freely pass each such spacer. To be able to move independently from the valid position to the invalid position. Can be done. a first upright barge against each engagement surface at the distal end of its containment line or Displaced along the storage line to a storage position near which one side of the barge lies From now on, each series of upper and lower first spacers 45 and 46 will be connected to the storage line of the barge. Each first spacer is displaced into a spacer effective position intervening therein. Each completed displacement The spacer and each of the distal end engagement surfaces described above hold the barge substantially upright. At that time, each crane cable 29, 30 should be removed from the barge. Can be done. The next barge to be stored along that storage line will be placed in each space that was last displaced. spacer is moved until it reaches the spacer, but then each next spacer along that retraction line Work continues as the spacer is moved to its effective position to support the second barge. It will be implemented sequentially.

In the illustrated example, each upper spacer 45 is in an inactive position shown in dotted lines in FIG. This is a pivot member that can be manually rotated between effective positions indicated by solid lines. Hold water Each lower spacer below the line must be activated remotely. This work A mechanical link connects each upper spacer and its corresponding lower spacer. This can be realized by a mechanism.

Alternatively, each spacer can be remotely actuated, e.g. electrically actuated. It can be made into something that is possible.

The unloading operation of the transport vessel consists of the following operations in the reverse order: The transport vessel returns to the loaded waterline. Each ballast tank is filled with water. Ships storing barges to be unloaded If the hold has been drained since the barge was loaded and is completely or partially empty of water, the Pump water into the hold until it reaches the level of the water line.

The door of each such hatch in the hold is then opened. Running lanes 26-28 Using the to the floating area, where each barge passes through one of the vessels from the hold to the ship. Allow each barge to return to a normal horizontal floating position in preparation for being floated out. The tension on the crane cable is completely relaxed.

If you wish to transport an unloaded barge, if the barge is Before reaching the delivery point, the barge is filled with water. Therefore the barge is the same It can be easily loaded and unloaded.

Pulling one end of a barge downwards instead of or as a supplement to an overhead lifting device Electrical power is installed in the onboard flotation area of each hold to assist in carrying out uprighting operations. Submersible traction devices operated by pneumatic or hydraulic motors may be installed.

The energy required to pull the barge upright due to the downward pulling force is Smaller than when you have to pull the end out of the water. Furthermore, this alternative method is superior in that it requires less free space above the water line.

As a measure of the significant increase in barge loading capacity made possible by this invention, the first ~ To give an example of a general type of transport ship as shown in Figure 3, there is a cargo ship with a dead weight of 220.0 tons. 00 tons, total length 325.74m, total width 46.49m, catchment water 26.02m. , a transport equipped with five holds (1) to (5) each having the length and width of the following dimensions: The ship is (1) Length 40m 1 Width 25m (2) 46.4m, ++25m (5) Length 40m 1 Width 25m (4) 5.0m, #25m (5) 4 4.4m, #1 8.5m. Each can store at least 64 barges (8 barges with 8 storage lines). However, the dimensions (total length) of each barge are 16 m long, 4.35 m wide, and 2.9 m high. It can carry up to 150 tons of cargo. Therefore, this transport ship is small. At least 320 barges were loaded on each barge with a total weight of 48,000 tons. can be transported together with other cargo. By comparison, transport ships of the same length and width are If such barges were to be stored in a single stage in a horizontal position, more than 55 barges would be stored. cannot be transported above. 320 or more vertical ships Designed to match the barge loading capacity of a transport vessel according to the present invention, which holds barges in a single stage. Horizontal barges must be able to be stored in six or more tiers for this purpose. Must not be too expensive.

The transport vessel according to the invention shown in Figure 7 is capable of transporting two upright barges. can. This transport ship was a high freeboard ship with a cargo hold located between each transverse bulkhead. The space is divided into two vertically overlapping compartments by a middle deck; The point is that the ship has a loading hatch for each compartment and that the ship does not enter the barge into any compartment. Except for the fact that ballast water can be injected up to the level of water that can be drained, the It has basically the same structure as that described above. Figure 7 shows the middle deck 48. Showing one of the large hold spaces between the bulkheads divided into upper and lower compartments 49 and 50. . The upper compartment 49 has loading hatches 51 and 52, and the ship has w, t, 1 Loading will be carried out while the vessel is submerged in water up to the water line marked. Lower compartment 5o is for loading Hatsuchi 5! I and 54, but the loading for this compartment is water line W, L.

It is carried out during the hiccups corresponding to 2. Each section 49 and 50 are shown in Figures 1 to 6. Each hold of the transport ship shown in Figure 1 has barge handling equipment and multiple containment lines.

Two barges 55 and 56 are shown in respective storage positions in the upper and lower compartments. ing.

FIG. 8 shows a part of another ship according to the invention. This vessel has an open watertight stern door type, and when the stern door is open, the open cargo loading area is immersed from the stern. It has a self-sinking ability that allows it to be flooded with water that enters the barge, allowing it to float. It can be directly introduced into a ship while still being unloaded. In these respects this ship is a shipbuilding Since the houses are based on the basic design of common knowledge, there is no need for detailed explanations. its basis The ship of this design is referred to as [Condock J] at the beginning of this specification. It is called Nadoc). However, the ship according to Figure 8 has each barge in the water inside the ship. The present invention is used to hold each barge stored upright and stored in that upright position. equipped by. The handling equipment includes a crane gant that spans the cargo loading area. 57, but this gun) IJ is a crane installed along both sides of the hull. It can be moved along tracks 58 and 59 by a plurality of electric motors (not shown). Wear. This gantry is equipped with a cable slide for hoisting two cables ls3.64. It carries a crane containing an electric motor 6o that drives a car 61.62, part 2 The main cable 65.64 is connected to the ship prior to exerting the lifting force required to right the barge. attached to each barge pulled into the barge. Inside this cargo loading area, there are Similar to the storage lines in each hold of the transport ship shown in the figure, there are multiple storage lines that are parallel to each other. Placed. Cranes 60-62 are used to move the barge along its storage line. ) Before the IJ travels along the transport ship, select an upright stretcher. along the gantry, i.e. laterally of the transport ship, in order to align it with the containment line. I can do it.

When using a ship as shown in Figure 10 as a barge, float the barge into the transport vessel. It can be pulled upright when it is pulled in or after it is pulled in.

A secondary barge for use with a transport vessel according to the invention is shown, for example, in FIGS. 9 and 10. It can have a general shape.

This barge shell consists of, for example, a steel frame 66 and one or more fiberglass frames stretched over the frame. A coating 65 of a fiber-reinforced synthetic polymer material can be used. this barge The minimum strength specifications will support this barge's cargo while it is raised out of the water. The fact that there is no need for it leaves no room for doubt.

The illustrated barge design has a flat rear end 67 which allows the barge to stand upright. An underlying support such as pad 20 (Fig. 5.4) in the retracted position when You can sit stably on top of your body. Inside the barge is a cup filled with gas. A support structure 68 is provided to which the cells 69 can be removably secured. like that Although the available cargo volume of the barge is reduced when the capsule is fitted. , the capsule contains water or other material with a similarly large or even higher specific gravity. can be filled. This capsule is designed so that the free cargo space of the barge is a product of a given specific gravity. The barge must float with the required freeboard when completely filled with cargo. Allows the volume of the free cargo space of the barge to be adjusted using one and the same capsule. such as those which are inflatable or consist of a retractable insert. It can be expanded.

This capsule has an enclosed cavity that can be used for upright operation of barges or be placed in such a position that it does not obstruct or significantly impede maintenance operations.

This barge may be provided with tanks as shown by symbols 70 and 71 at the bottom of its interior. However, these tanks cannot be filled for normal navigation of the barge. Both have gas inlet holes and drainage holes with pulp. Barge in horizontal position said tongue to cause or assist in movement from to vertical position or vice versa. By supplying high pressure C02 or other suitable gas through its gas inlet The water in the tank can be drained and replaced with the introduced gas. Ru.

The barge itself is equipped with one or several suitable compressed gas containers or pressure gas The source may be installed in another suitable location, for example in the floating area of the cargo hold of the transport vessel. It doesn't matter.

As already explained, although the present invention essentially has the function of a barge, A long floating container for loading cargo that does not have the geometrical form of a barge It can be carried out using . Figure 11 shows a pair of buoyant objects in the shape of a long rectangular parallelepiped. Cargo containers and their use on the ships described with respect to Figures 1 to 10.
