Description

  The present invention relates to a ballast-treated water supply ship and a ballast-treated water supply method, and more specifically, clean ballast water (ballast treatment) in which aquatic organisms and bacteria are killed in advance on a ship that does not have a ballast water treatment device. The present invention relates to a ballast-treated water supply ship that can supply water according to the ballast pump capacity of the ship and a ballast-treated water supply method using the same.

  Ballast water drained from cargo ships such as container ships is mixed with aquatic organisms and bacteria that live in the port from which the water was taken. As a result, the destruction of ecosystems, such as the replacement of existing species with species that did not originally live in the sea, has become serious.

  Against this background, a convention for the regulation and management of ship ballast water and sediment (hereinafter referred to as the Convention) was adopted at the diplomatic meeting of the International Maritime Organization (IMO), and the obligation to implement ballast water management. Is scheduled to be applied from 2009 and after construction ships.

For this reason, it is required that ships can drain clean ballast water that satisfies the Convention.
JP 2004-160437 A (Configuration of ozone treatment) JP 2003-200156 A (Structure of slit plate) US Pat. No. 6,125,778 (configuration in which ozone gas is injected into the ballast tank)

  In order to be able to drain clean ballast water that satisfies the convention from the ship, a processing device is installed in the ship to kill the aquatic organisms and bacteria in the water so that they are below the specified value. A method of treating ballast water during water intake is conceivable.

  However, in the case of an existing ship, since existing piping and devices take up space, it may be difficult to secure a space for newly installing a processing apparatus inside the ship.

  For this reason, the present inventor provides a ballast-treated water supply ship equipped with a treatment device capable of generating clean ballast water (ballast-treated water) that has been killed until the aquatic organisms and bacteria fall below a predetermined value. We are preparing and considering supplying ballast treated water from this ballast treated water supply ship to a ship that does not have a ballast water treatment device. is there.

  In other words, the ballast water intake capacity is determined by the ship's ballast pump capacity, but ships with various capacity ballast pumps come and go at each port, so the ballast water supply ship needs to be able to handle these various ships. There is.

  However, in reality, it is impossible to prepare ballast-treated water supply vessels having different treatment capacities (supply capacities) in order to cope with various vessels.

  In addition, if a large ballast-treated water supply ship with a processing capacity sufficient to handle the maximum capacity of the ship is prepared, there is a problem that it is difficult to secure a berthing space in a narrow port. Also worse. Moreover, since the ballast water is not always supplied to a large ship, there is a problem that the efficiency is rather poor when it is supplied to a small ship.

  On the other hand, if a small ballast-treated water supply ship is prepared giving priority to anchoring space and maneuverability, it will take time to complete the supply of the required amount of ballast-treated water because the capacity to handle large ships is insufficient. As a result, there is a problem that the operation schedule of the ship is disturbed.

  Therefore, the present invention flexibly uses clean ballast water (ballast treated water) that has been killed in advance until the aquatic organisms and bacteria fall below a predetermined value, to the ballast pump capacity of a ship that does not have a ballast water treatment device. It is an object of the present invention to provide a ballast treated water supply ship and a ballast treated water supply method that can be supplied correspondingly.

A ballast-treated water supply ship and a ballast-treated water supply method that can be supplied correspondingly can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view showing a part of an example of a ballast treated water supply ship according to the present invention.

  Inside the hull 2 of the ballast-treated water supply ship 1, a processing device 4 for processing ballast water taken from a sea chest 3 provided near the bottom of the ship, and ballast water processed by the processing device 4 are stored. A storage tank 5 is provided. Reference numeral 21 denotes a navigation screw.

  Here, seawater, fresh water, etc. are used for ballast water, and seawater is preferably used in the present invention. Such ballast water includes zooplankton, phytoplankton, aquatic organisms such as microorganisms and bacteria such as Escherichia coli that inhabit the taken water area.

  The treatment device 4 only needs to be able to kill aquatic organisms and bacteria in the ballast water taken from the sea chest 3 to the extent that the convention is satisfied. For example, heat, ultrasonic waves, ultraviolet rays, silver ions, electricity, etc. Physical treatment method used, mechanical treatment method using filtration, shearing force, cavitation, etc., chemical treatment method using ozone, oxygen removal, chlorine, etc., a combination of these two or more treatment methods A processing method etc. are mentioned.

  An example of the processing apparatus 4 preferable in the present invention will be described with reference to FIG. 2, but the processing apparatus 4 is not limited to what is illustrated.

  FIG. 2 is a block diagram showing an example of the treatment device 4, 41 is a filter, 42 is a water intake pump, 43 is a treatment line, 44 is an ozone mixing device, 45 is an ozone generator, 46 is a slit plate, and 47 is deaerated. A tank 48 is an exhaust ozone decomposing apparatus.

  By the operation of the water intake pump 42, ballast water is taken into the processing device 4 from the sea chest 3, and in the process of being transferred through the processing line 43, processing for killing aquatic organisms and bacteria is performed.

  The filter 41 is provided to remove impurities from the ballast water introduced into the processing device 4 by the operation of the water intake pump 42. Since the aquatic organisms and bacteria are killed by the ozone injection by the subsequent ozone mixing device 44 and the slit plate 46, the filter 41 only needs to remove relatively large contaminants such as underwater dust.

  The ozone mixing device 44 mixes the ozone generated by the ozone generator 45 into the ballast water transferred through the treatment line 43 by the operation of the water intake pump 42 to strongly aquatic aquatic organisms and bacteria in the ballast water. Chemically killed by action. Here, although the example using the gas-liquid mixing apparatus (ozone injector) which gas-liquid mixes the ballast water and ozone in the processing line 43 is shown as the ozone mixing apparatus 44, ozone of predetermined concentration is shown in ballast water. If it can mix, it will not specifically limit. For example, a static mixer such as a static mixer or a line mixer can be used.

  The ozone generator 45 includes, for example, a compressor 451, an oxygen generator 452, and an ozone generator 453, and ozone generated through the oxygen generator 452 and the ozone generator 453 passes through an ozone supply line 454 by the compressor 451. The ozone mixing device 44 is supplied with ozone of a predetermined concentration in the ballast water.

  The slit plate 46 passes ballast water mixed with ozone by the ozone mixing device 44 at a high pressure, and mechanically destroys and kills aquatic organisms and bacteria in the ballast water by the shearing force generated at that time. To do.

  Details of the slit plate 46 are shown in FIGS.

  3 is a cross-sectional view showing the slit plate 46 in the processing line 43, and FIG. 4 is a cross-sectional view taken along line (iv)-(iv) in FIG. 3. As shown in FIG. Is disposed so as to block the entire flow path of the processing line 43.

  A plurality of slit-shaped openings 461 are formed in the slit plate 46. The opening width of the opening 461 is set to a width that can sufficiently exert the effect of destroying aquatic organisms and bacteria in the ballast water by a shearing force, and is preferably 200 μm to 500 μm. Thereby, aquatic organisms of about 10 μm can be killed by a shearing phenomenon that occurs when ballast water is passed.

  Ballast water transferred through the treatment line 43 is pumped at a high pressure toward the slit plate 46 by the operation of the water intake pump 42. The pumped ballast water tries to pass through the slit-like opening 461 of the slit plate 46 in a turbulent state, and a shear phenomenon occurs when passing through the opening 461, thereby destroying aquatic organisms and bacteria in the ballast water. And killed.

  In order to exhibit the effect of destruction and killing due to the shearing force, the slit plate 46 is preferably attached in a direction orthogonal to the flow direction of the ballast water.

  In addition, although the slit plate 46 is attached intimately in the processing line 43, although not shown, it is preferable that the slit plate 46 is interposed in the processing line 43 by a flange or the like so that it can be easily removed and cleaned.

  The shape of the plurality of slit-like openings 461 formed in the slit plate 46 is preferably a long and narrow rectangular shape as illustrated in FIG. The number of the openings 461 is not particularly limited, and is appropriately set according to the pressure loss of the ballast water and the occurrence of the shear phenomenon.

  Although all the openings 461 may be formed to have the same length, as shown in FIG. 5, the center portion may be long and the end portion may be shortened according to the cross-sectional shape of the processing line 43. Good.

  Further, the shape of each opening 461 is not limited to a linear shape, and may be formed in a curved shape such as an arc as shown in FIG.

  Furthermore, the number of slit plates 46 disposed in the processing line 43 is not limited to one, and a plurality of sheets (46A, 46B) may be disposed at intervals as shown in FIG. . The number of sheets is not particularly limited as long as it is plural.

  When a plurality of slit plates 46A and 46B are provided, it is preferable that the width, size, number, and shape of the openings 461 of the slit plates 46A and 46B are made different. It is also preferable to arrange the openings 461 of the adjacent slit plates 46A and 46B differently, for example, so that the length directions of the openings 461 of the slit plates 46A and 46B are orthogonal to each other. By these, a shear phenomenon can be exhibited more effectively and the destruction and killing effects of aquatic organisms and bacteria in the ballast water can be further improved.

  The ballast water after passing through the slit plate 46 is sent to the deaeration tank 47, and undissolved surplus ozone in the ballast water is deaerated. In the deaeration tank 47, a partition wall 471 standing from the bottom of the tank to the front of the tank ceiling and a partition wall 472 extending from the tank ceiling to the front of the tank bottom alternately The ballast water is formed in parallel, and the upward flow path and the downward flow path are alternately formed. As a result, the ballast water introduced into the deaeration tank 47 alternately passes through the upward flow path and the downward flow path, and in the process, surplus ozone mixed in the form of bubbles in the ballast water is removed from the ballast water. It is removed and stored in the exhaust ozone chamber 473 at the upper part of the tank.

  Exhaust ozone accumulated in the exhaust ozone chamber 473 is sent from the deaeration tank 47 to the exhaust ozone decomposing device 48 where it is decomposed and discharged, for example, from the deck to the outside of the ship.

  In this way, the ballast water that has passed through the treatment device 4 becomes clean ballast water (ballast treatment water) that has been killed so that aquatic organisms and bacteria are below a predetermined value.

  In the embodiment shown in FIG. 2, ozone is mixed in the ballast water by the ozone mixing device 44 and then processed by passing through the slit plate 46. However, the present invention is not limited to this, and the slit plate 46 is allowed to pass. You may comprise so that ozone may be mixed with the later ballast water by the ozone mixing apparatus 44, and may be processed.

  Ballast water treated by passing through the treatment device 4 is sent to the storage tank 5 and stored in the storage tank 5. In the stored ballast water, since excess ozone is removed by the deaeration tank 47, there is no problem of corroding the tank.

  Ballast treated water stored in the storage tank 5 is supplied to inject water into a ballast tank of a ship (supply target ship) such as a container ship anchored at a port. For this reason, a supply pump 6 is provided in the hull 1 to take in the ballast treated water from the storage tank 5 and supply it to the ship to be supplied, and the treated water supply line 7 is activated by the operation of the supply pump 6. It comes to be supplied through.

Here, it is assumed that the supply pump 6 has a capacity of 1000 m ³ / hr.

  One end of the treated water supply line 7 is extended on the deck 22 to form a treated water supply pipe 8 so that the ballast treated water in the storage tank 5 can be supplied from the deck 22 to the outside of the ship.

  The treated water supply line 7 is provided with a flow rate adjusting valve 9 and a flow meter 10.

  FIG. 8 is a plan view showing details of the treated water supply pipe 8.

  The treated water supply pipe 8 is connected to the treated water supply line 7 in the hull 2 and extends on the deck 22 in the bow direction (right direction in the figure), and intersects with the main supply pipe 81. And a plurality (five in the illustrated example) of auxiliary supply pipes 82 to 86 extending in the direction crossing the hull 2 are provided.

  Hose connection ports 821, 822 to 861, and 862 are provided at both ends of each of the sub supply pipes 82 to 86, respectively. The treated water supply pipe 8 receives not only the ballast treated water but also the ballast treated water through these hose connection ports 821, 822 to 861, 862.

  The respective hose connection ports 821, 822 to 861, and 862 are opened and closed by open / close valves 823, 824 to 863, and 864, respectively.

The sub supply pipes 82 to 86 are not the same diameter but have different diameters, and thus the hose connection ports 821, 822 to 861 and 862 have different diameters. Here, the auxiliary supply pipe 82 is for 3000 m ³ / hr, the auxiliary supply pipe 83 is for 2000 m ³ / hr, the auxiliary supply pipe 84 is for 1000 m ³ / hr, the auxiliary supply pipe 85 is for 800 m ³ / hr, and the auxiliary supply pipe 86 is a supply pipe for 600 m ³ / hr. For this reason, it is connectable with the connection part of the hose which has various diameters according to the supply amount of ballast processing water.

In the present embodiment, since the supply pump 6 is assumed to have the ability of 1000 m ³ / hr, when the supply amount of the treated ballast water is 1000 m ³ / hr, the sub-supply pipe 84 of which are used exclusively It will be.

  In FIG. 8, reference numeral 811 denotes a check valve provided in the main supply pipe 81, and the ballast treated water heading from the treated water supply line 7 in the hull 2 through the main supply pipe 81 to the sub supply pipes 82 to 86. Is allowed to flow, and the flow in the opposite direction is prevented.

  9 and 10 show a method of supplying ballast treated water to a target ship for supplying ballast treated water having a ballast pump capacity exceeding the supply capacity of the ballast treated water supply ship 1 by the ballast treated water supply ship 1.

  In the present invention, a supply target ship is a ship that stores supplied ballast treated water in a ballast tank.

Here, it is assumed that the ballast pump capacity of the ship to be supplied is 3000 m ³ / hr. Since the capacity of the supply pump 6 of the ballast treated water supply ship 1 shown in the present embodiment is 1000 m ³ / hr, it is possible to cope with this supply target ship by using three ballast treated water supply ships 1. .

  First, three ships (1A, 1B, 1C) are juxtaposed in parallel to a supply target ship 200 that requires ballast treated water. Each of the ballast-treated water supply ships 1A to 1C is provided with a mooring device 11 for mooring each other. By this mooring device 11, the adjacent ballast-treated water supply vessels 1A to 1C have a certain distance. Moored to maintain.

Thereafter, one hose connection port 841 of the sub supply pipe 84 for 1000 m ³ / hr provided in the treated water supply pipe 8 of the ballast treated water supply ship 1A farthest from the supply target ship 200 is adjacent thereto. The hose 801 connects the other hose connection port 842 of the 1000 m ³ / hr sub supply pipe 84 provided in the treated water supply pipe 8 of the ballast treated water supply ship 1B.

Further, one hose connection port 831 of the secondary supply pipe 83 for 2000 m ³ / hr provided in the treated water supply pipe 8 of the middle ballast treated water supply ship 1B and the treatment of the innermost ballast treated water supply ship 1C. The hose 802 connects the other hose connection port 832 of the sub supply pipe 83 for 2000 m ³ / hr provided in the water supply pipe 8.

Further, the supply target ship 200 is connected to one hose connection port 821 of the 3000 m ³ / hr auxiliary supply pipe 82 provided in the treated water supply pipe 8 of the ballast processed water supply ship 1C closest to the supply target ship 200. A water intake hose 201 extending from the side is connected.

  Here, in the ship 200 to be supplied, a water intake pipe 203 having a water intake hose 201 is provided in the hull 202, and this water intake pipe 203 is ballasted from the sea chest 205 by a secondary water injection line 204 provided in the hull 202. Ballast treated water from the ballast treated water supply ship 1 is connected to a ballast tank (not shown) by operation of a ballast pump 207 connected to an existing main water injection line 206 for taking water. Water is being injected. Selection of the ballast water injection source in the supply target ship 200 such as whether the ballast water is injected from the sea chest 205 or supplied from the ballast-treated water supply ship 1 is performed by an on-off valve 208 provided in the main water injection line 206. This is performed by selective opening / closing control of an opening / closing valve 209 provided in the auxiliary water injection line 204.

Thus, after connecting each ballast process water supply ship 1A-1C and the supply object ship 200 by the hose 801, 802, 201, the ballast of the supply pump 6 and each supply object ship 200 of each ballast process water supply ship 1A-1C. When the pump 207 is operated, the ballast treated water supply vessel 1A to the ballast treated water supply vessel 1B is supplied with a ballast treated water of 1000 m ³ / hr which is the supply capacity of the ballast treated water supply vessel 1A through the treated water supply pipe 8. Is supplied to the ballast treated water supply ship 1B, and the ballast treated water supply ship 1A to the ballast treated water supply ship 1A is supplied with the ballast treated water supply ship 1A through the treated water supply pipe 8 at a rate of 1000 m ³ / hr. water is relayed, the treated ballast water 1000 m ³ / hr is a supply capacity of the treated ballast water supply boat 1B, ballast Sum treated ballast water 1000 m ³ / hr supplied from physical water supply vessel 1A has merged 2000 m ³ / hr treated ballast water is supplied to the treated ballast water supply boat 1A, further, the treated ballast water supply vessels 1C 2000 m ³ / hr of ballast treated water supplied from the ballast treated water supply ship 1B is relayed to the supply target ship 200 by the treated water supply pipe 8, and the supply capacity of the ballast treated water supply ship 1C is 1000 m ^3. / and treated ballast water hr, treated ballast water in total 3000 m ³ / hr of the treated ballast water is confluence of 2000 m ³ / hr supplied from treated ballast water supply boat 1B is supplied to the supply target vessels 200.

  At this time, the open / close valve of each hose connection port that is not used is closed. Moreover, since the check water 811 is provided in each treated water supply pipe 8 of each ballast treated water supply ship 1A-1C, the ballast treated water supplied from the other ballast treated water supply ship 1 is each. There is no backflow to the treated water supply line 7 side.

In the object of supply vessels 200, can be by the operation of the ballast pump 207 having a capacity of 3000 m ³ / hr, accept treated ballast water 3000 m ³ / hr supplied from treated ballast water supply vessels 1C, usually from sea chest 205 Ballast treated water is stored in the ballast tank in the same manner as when taking ballast water.

  Therefore, according to the ballast-treated water supply ship 1 and the ballast-treated water supply method using the same according to the present invention, the ballast pump capacity of the supply target ship 200 can be increased by supplying the ballast-treated water by a plurality of ships as necessary. Corresponding ballast water can be supplied. For this reason, even if it does not bother to enlarge the ballast treated water supply ship 1, it becomes possible to supply ballast treated water flexibly corresponding to the ballast pump capability of the supply target ship 200 that does not have a ballast water treatment apparatus. .

  In short, when the capacity of the supply pump 6 of the ballasted water supply ship 1 is X and the capacity of the ballast pump of the supply target ship 200 is Y, if Y> X, Y / X ships of the ballasted water supply ship 1 are prepared. You can do it.

  Further, as shown in FIG. 1, the flow rate adjusting valve 9 is provided in the treated water supply line 7 of the ballast treated water supply vessel 1, so that the flow rate adjusting valve 9 is appropriately adjusted as necessary. The supply amount of ballast treated water can be adjusted.

  Furthermore, according to the present invention, the supply target ship 200 side is provided with a water intake pipe 203 having a water intake hose 201 and is connected to the existing main water injection line 206 via the on-off valves 208 and 209. This eliminates the need for major renovation work, such as when processing equipment is installed in

  The treated water supply line 7 of the ballast treated water supply ship 1 is provided with a flow meter 10 as shown in FIG. 1, so that the flow rate of the supplied ballast treated water can be measured. As shown in FIG. 1, for example, in the steering chamber 23 of the ballast treated water supply ship 1, a display unit 10 a that displays information such as an integrated flow rate and an estimated supply completion time based on the measurement result of the flow meter 10 is provided. It has been. Therefore, a necessary amount of ballast water can be supplied to the supply target vessel 200, and the information can be confirmed by the display unit 10a. Further, it is possible to charge according to the measurement result of the flow meter 10. Such billing information is also displayed on the display unit 10a.

  In the above aspect, the ballast treated water treated by the treatment device 4 is stored in the storage tank 5, and the ballast treated water in the storage tank 5 is supplied to the supply target ship 200. According to this aspect, since the ballast water can be generated and stored, for example, the ballast water is generated and prepared in advance in accordance with the schedule of the port call time of the supply target ship 200, cargo handling work, and the like. It can be quickly supplied when necessary.

  Further, by having the storage tank 5, whether or not the ballast water in the storage tank 5 is clean ballast water in which aquatic organisms and bacteria have been killed to such an extent that the convention is satisfied. It is also possible to check and confirm in advance by sampling. Therefore, it can be shown to the supply target ship 200 based on the sampling result that it is clean ballast treated water that has been killed so that aquatic organisms and bacteria are less than or equal to a predetermined value. Ballast treated water can be provided.

  However, the present invention is not limited to the one having the storage tank 5 as described above, and the storage tank may not necessarily be provided like the ballast treated water supply ship 100 shown in FIG. In this case, the ballast treated water supply ship 100 supplies the ballast treated water discharged from the treatment device 4 as it is to the supply target ship 200 and the other ballast treated water supply ship 1 or 100 from the treated water supply pipe 8. can do. In FIG. 11, the same reference numerals as those in FIG. 1 indicate the same configurations, and thus detailed description thereof is omitted here.

  According to this aspect, since the ballast treated water supply ship 100 does not need to store the ballast treated water therein, the treatment device 4, the supply pump 6, the treated water supply line 7, and the treated water supply pipe 8 can be installed. Compared to the case of having a storage tank, it is possible to provide a compact ship as compared with the case of having a storage tank, and there is an advantage that a ballast-treated water supply ship having high mobility can be provided in a narrow harbor.

  In the case of the ballast-treated water supply ship 100 that does not have such a storage tank, the treatment effect is confirmed by sampling the ballast-treated water after being treated by the treatment device 4 and examining the number of living aquatic organisms and bacteria. It is preferable to provide an inspection system for this purpose so that the inspected ballast water can be supplied to the supply target ship 200.

  FIG. 12 shows another embodiment of the treated water supply pipe. The same reference numerals as those in FIG. 8 indicate the same configurations.

  The treated water supply pipe 8 ′ is provided with one sub supply pipe 87 branched in a T shape at the tip of a main supply pipe 81 provided on the deck 22. Hose connection ports 871 and 872 are provided at the distal ends of the sub supply pipes 87, respectively. Reference numerals 873 and 874 are open / close valves.

  Since the hose connection ports 871 and 872 have the same configuration, the hose connection port 871 will be described with reference to FIG.

  The hose connection port 871 is provided concentrically so that a plurality of hose connection ports 871a to 871e having different diameters protrude from the hose connection port 871a having a larger diameter toward the hose connection port 871e having a smaller diameter. ing.

Here, for example, the hose connection port 871a is for 3000 m ³ / hr, the hose connection port 871b is for 2000 m ³ / hr, the hose connection port 871c is for 1000 m ³ / hr, the hose connection port 871d is for 800 m ³ / hr, and the hose connection The port 871e is a hose connection port for 600 m ³ / hr. For this reason, as with the treated water supply pipe 8 described above, depending on the supply amount of the ballast treated water to the supply target ship, it can be connected to a connecting portion of a hose having a plurality of types of bore diameters. According to the water supply pipe 8 ′, it is possible to connect the connecting portions of the hose having a plurality of types of diameters with only one sub supply pipe 87, so that the installation space on the deck 22 can be remarkably saved. Of course, in particular, as in the case of the treated water supply pipe 8 shown in FIG. 8, the connection point between the supply side hose and the water reception side hose is greatly different in the front-rear direction on the deck 22. Since both the supply side hose and the water receiving side hose can be connected at substantially the same location, the operation can be simplified.

  Further, as a simple connection method, several types of connection fittings may be prepared, and the connection fittings may be replaced depending on the balance of the capabilities of the ship supplied with the ballast water and the ballast pump of the supply ship.

  In any of the above-described ballast treated water supply ships 1, 100, the treatment device 4, the supply pump 6, the flow rate adjustment valve 9 on the treated water supply line 7 and the flow meter 10 may be installed on the deck 22. .

  Further, the supply of ballast treated water from the ballast treated water supply ships 1, 100 is not limited to a mode in which a hose extending from the supply target ship side is connected to the treated water supply pipe 8. For example, although not shown, in addition to the treated water supply pipes 8 and 8 ′ of the ballast treated water supply ships 1 and 100, a hose for supplying ballast treated water to the supply target ship is provided, and this hose is supplied to the supply target ship. It may be configured such that it can be connected to a water intake on the ship side.

  Furthermore, as another embodiment of the processing device 4, a membrane device such as an MF membrane or a UF membrane that can be removed by filtering aquatic organisms and bacteria can be used. Further, as shown in FIG. 2, an ozone mixing device 44, an ozone generator 45, and a degassing tank 47 may be arranged at the subsequent stage of the membrane device to perform ozone injection and excess ozone deaeration.

  The ballast treated water supply ships 1 and 100 described above are examples of ships that can navigate independently by the screw 21, but are not limited thereto. Therefore, the present invention may be a barge ship that does not have an engine for autonomous navigation.
