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

In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 to 3, the mobile harbor 100 according to the embodiment of the present invention has a hull 110 formed of a single hull tanker and a rail formed forward and backward on the hull 110. 120 and a gantry crane 130 installed to be movable along the rail 120 to unload the container.

Here, the unloading is an unloading to lift a container from the container ship 200 and load it on the shuttles 300 and 400, and a load to lift the container from the shuttle 300 and 400 and load the container to the container ship 200 ( loading) and loading / unloading between the mobile harbor 100 and the container ship 200 or the shuttles 300 and 400.

The mobile harbor 100 is constructed by modifying a single hull type tanker, in particular a single hull type very large crude carrier (VLCC).

Oil tankers using single hulls are made of a single layer of steel plates on the bottom and wall of oil tankers, so when oil tankers are damaged by various accidents, oil is easily leaked, which may cause serious environmental pollution in an accident. On the other hand, oil tankers using double hulls are formed with two layers of steel plates at the bottom and wall of the tanker, and two layers of steel plates are formed at intervals of 1 to 3 meters, so that the inner steel plate will not be damaged even if an external hull is damaged in an accident. In this case, the oil spill can be prevented.

Therefore, in recent years, there has been a global trend to restrict the use of single hulls and to mandate the use of double hulls. In particular, the Marine Pollution Prevention Convention (MARPOL) prohibits the use of single hull tankers. The Republic of Korea has also amended the Marine Environment Management Act to stipulate that "Single hull tankers are allowed to operate until the delivery date in 2010".

Since marine operations of single hull tankers are prohibited, they must be disposed of unless recycled, so in the future, single hull tankers can be purchased at a very low price.

The mobile harbor 100 according to an embodiment of the present invention is dried by purchasing an inexpensive single hull tanker which is prohibited in the future as described above and modifying it. That is, the hull 110 of the mobile harbor 100 is a single hull tanker. Therefore, the cost for drying the mobile harbor 100 can be greatly reduced.

In particular, large tankers are generally oil tankers having a loading capacity of 300,000 tons or more, and their sizes are very large, and the deck area is approximately 1500 to 2000 square meters, which is wide enough to load more than 1000 containers in one floor of a standard container. . In addition, the width of the deck of such an ultra-large tanker is wide enough to combine a plurality of the crane 130 for the transport of the container.

In addition, in the case of a very large tanker, the freeboard is high, so that the container may be unloaded even if the height of the crane 130 is not high. That is, since the height of the support of the crane 130 can be formed low, the center of gravity of the crane 130 can be lowered, and the moment can be reduced, so that the container can be unloaded more stably. In addition, the adjustment of the draft (draft) is also easy, it can be anchored even in the sea without deep water can be unloading work.

Therefore, the hull 110 may use a large hull type tanker of a single hull type, and in this case, the hull 110 may be used as a temporary loading dock of the container, thereby maximizing the utilization value of the mobile harbor 100. .

In the embodiment of the present invention will be described as an example of using a single hull type super tanker as the hull 110 of the mobile harbor (100).

The rail 120 is formed on the deck of the hull 110 in the front and rear direction, the crane 130 is coupled to move in the front and rear direction along the rail 120. The rail 120 and the crane 130 may function similarly to a gantry crane and a rail installed in an apron.

The rail 120 may be installed after removing the structures on the deck of the hull 110, which is a single hull type oil tanker, to provide space for the movement of the crane 130 and temporary unloading of the container. The structures on the deck can be sufficiently removed. In other words, the rail 120 and the crane 130 may be installed after flattening at least a part of the deck of the hull 110.

The crane 130 may be installed in plurality in accordance with the length of the hull 110, it is installed to be movable in the front and rear direction along the rail (120). Therefore, the container ship 200 and the shuttle (300, 400) can be carried out at various locations.

In addition, the crane 130 may be provided detachably to the rail (130). Therefore, the number of the crane 130 can be adjusted as needed.

And, the girder 131 of the crane 130 is formed to extend in the left and right direction of the hull 110. In detail, the girder 131 is outside of the container ship 200 and the shuttle 300 and 400 when the container ship 200 and the shuttles 300 and 400 are moored to the mobile harbor 100. It may be formed to extend to the side end portion.

As described above, since the crane 130 is movable in the front-rear direction and the girder 131 extends long enough, the mobile harbor 100 may be any of the container ship 200 or the shuttle 300, 400. The container loaded at the position can be transported.

Hereinafter, a container unloading process using the mobile harbor 100 having the above configuration will be described.

The container ship 200 to which the container is being loaded, or to which the container is to be loaded, is anchored at a specific point in the sea, not at the harbor wall Q. At this time, the container ship 200 may be moored to a buried anchor (not shown) embedded in the seabed.

In addition, the mobile harbor 100 is docked with the container ship 200 so that one side is in contact with the container ship 200. The container ship 200 and the mobile harbor 100 are firmly connected to each other by various mooring means, and the mobile harbor 100 may also be moored by a buried anchor (not shown) like the container ship 200. .

At this time, since the buried anchors are pre-installed on the sea floor, the mooring position on the sea of the container ship 200 and the mobile harbor 100 can be maintained substantially constant.

Shuttles 300 and 400 reciprocating between the quay wall Q and the mobile harbor 100 are moored on the other side of the mobile harbor 100. The shuttles 300 and 400 transfer the container unloaded from the container ship 200 by the mobile harbor 100 to the inner wall Q or transfer the container loaded from the inner wall Q to the mobile harbor 100. Transfer to.

The shuttles 300 and 400 are floating bodies including a loading space for loading a container, and the top surface may be wide and flat to provide the loading space.

The shuttles 300 and 400 include a power shuttle 300 that can move itself with its own power source such as a thruster (not shown), a barge that can load a container, and a predetermined mooring means. A non-powered shuttle 400 constructed and moved by the tugboat 500 may be provided.

In this case, like the mobile harbor 100, the power shuttle 300 may be a modified deck portion of a single hull tanker, and a tanker having a smaller size than the mobile harbor 100 may be used. In this case, since the single hull tanker close to the scrap metal price to be disposed of is used as a shuttle, the unit cost of the power shuttle 300 can be greatly reduced.

In addition, in the case of the non-powered shuttle 400, the tugboat 500 may be selectively connected to the front end or the rear end of the non-powered shuttle 400, and accordingly, the tugboat without changing the front-rear direction of the non-powered shuttle 400 By switching only the connection position of 500, the non-powered shuttle 400 can be conveniently reciprocated between the quay wall Q and the mobile harbor 100.

After the shuttles 300 and 400 are moored to the mobile harbor 100, the shuttles 300 and 400 may be moored to a buried anchor (not shown) like the container ship 200 and the mobile harbor 100.

When both the container ship 200, the mobile harbor 100, and the shuttles 300 and 400 are moored to a buried anchor having a large bearing capacity, fluctuations of the vessels 100, 200, 300, and 400 are minimized. The container can be unloaded in a stable manner. In particular, the mobile harbor 100 is connected to the container ship 200 and the shuttle (300, 400) as well as mooring itself to the buried anchor itself can be carried out more stable container transport through the crane 130 have.

In this embodiment, the power shuttle 300 and the non-powered shuttle 400 are connected to the mobile harbor 100 by way of example. However, this is only an example, using only a plurality of power shuttles or a plurality of non-powered shuttles. Various modifications of the embodiment are possible within the scope of the spirit of the present invention, such as using only.

The container unloading 100 between the container ship 200 and the shuttles 300 and 400 using the mobile harbor 100 may be started after the shuttles 300 and 400 are moored to the mobile harbor 100. have.

When the shuttles 300 and 400 are anchored to the mobile harbor 100 and the buried anchor, the crane 130 transfers containers from the container ship 200 to the shuttles 300 and 400, or The container is transferred from the shuttles 300 and 400 to the container ship 200.

In this case, the crane 130 may transport the containers individually, but may also transport pallets 610 loaded with a plurality of containers for faster unloading. When unloading using the pallet 610, since the number of containers can be moved in one movement of the crane 130, the unloading speed can be significantly improved.

4 is a perspective view illustrating the appearance of the pallet of FIG. 2, and FIG. 5 is a view illustrating a container loaded on the pallet of FIG. 4.

4 and 5, the pallet 610 may include a base frame 611 supporting a load of a container, side frames 613 extending downward from both end portions of the base frame 611, and the base. It may include a cone 617 formed on the frame 611 to secure the container.

The base frame 611 is formed wide enough so that a container can be stacked in layers and a plurality of containers in one layer.

When the pallet 610 is placed on a flat bottom, the base frame 611 is spaced a predetermined distance from the bottom surface by the side frame 613. At this time, the height of the side frame 613 is formed so that the transport vehicle 620 to be described later into the lower space 615 of the base frame 611. That is, it is formed higher than the height of the transport vehicle 620.

When the container is transferred from the container ship 200 to the shuttles 300 and 400, the shuttles 300 and 400 move to the inner wall Q after completing the container transfer from the container ship 200 to the inner wall. Mooring to (Q). When the mooring of the quay wall Q of the shuttles 300 and 400 is completed, container unloading on the quay wall using the transport vehicle 620 is started.

When a container is transferred from the shuttles 300 and 400 to the container ship 200, the shuttles 300 and 400 move to the inner wall Q after completion of the container transfer to the container ship 200. Mooring to (Q). When the mooring of the quay wall Q of the shuttles 300 and 400 is completed, container loading on the quay wall using the transport vehicle 620 is started.

The shuttles 300 and 400 may reciprocate between the quay wall Q and the mobile harbor 100 and repeat the above loading and unloading operation. In particular, by operating the plurality of shuttles (300, 400) sequentially, if the container is continuously unloaded in the mobile harbor (100) can greatly shorten the sea wait time and the total loading time of the container ship 200 have.

Hereinafter, with reference to the drawings, a detailed container unloading process between the shuttle (300, 400) and the inner wall will be described.

6 is a view showing a loading and unloading operation between the shuttle and the quay in the container loading method using a mobile harbor according to an embodiment of the present invention, Figure 7 is a view showing an example of the transport vehicle of FIG.

6 and 7, the shuttles 300 and 400 may be docked such that one end thereof contacts the inner wall Q. One end of the shuttle (300, 400) in contact with the inner wall may be formed in a straight line to be in close contact with the inner wall.

A ramp 630 may be installed on the quay wall Q to match the height of the shuttles 300 and 400 with the decks. The lamp 630 is in close contact with the shuttles 300 and 400 so that the transport vehicle 620 can be stably operated.

The transport vehicle 620 may be used a heavy transporter (heavy transporter) generally used in the shipbuilding process, the transport vehicle 620 is a loading unit 621 and a driving unit for loading goods ( 623). The loading unit 621 may include a moving means such as a hydraulic cylinder (not shown) so that the loading surface can be moved in the vertical direction. By using the heavy transporter previously used as the transport vehicle 620, it is possible to reduce the unloading cost.

The transport vehicle 620 may enter and exit the decks of the shuttles 300 and 400 through the ramp 630 and transport the pallet 610. That is, the transport vehicle 620 may reciprocate between the quay wall Q and the decks of the shuttles 300 and 400.

In the case of unloading from the shuttles 300 and 400 to the quay wall Q, the transport vehicle 620 passes through the ramp 630 with the loading part 621 empty and the shuttles 300 and 400. Go to the deck. The transport vehicle 620 moves inside the lower space 615 of the pallet 610, and then lifts the pallet 610 until it is spaced apart from the deck by operating the loading unit 621 upward. . Thereafter, the transport vehicle 620 passes again through the ramp 630 to the inner wall Q to move to a predetermined loading dock.

In the case of unloading from the quay wall Q to the shuttles 300 and 400, the transport vehicle 620 loads the lamp 630 with the pallet 610 loaded with a container on the loading part 621. Pass through to the deck of the shuttle (300, 400). The transport vehicle 620 is lowered from the loading part 621 until the side frame 613 of the pallet 610 is supported on the deck, and the base frame 611 and the loading part 621 are spaced apart. To work. When the pallet 610 is stably seated on the deck, the transport vehicle 620 again moves through the ramp 630 to the inner wall.

Here, the mobile harbor 200 or the shuttle (300, 400) using a variety of short-range communication module, such as RFID communication, Bluetooth, Zigbee, to accurately control the position where the transport vehicle 620 unloads the pallet 610 The location information of the pallet 610 may be transmitted to the transport vehicle 620.

Since the container is unloaded between the shuttles 300 and 400 using the transport vehicle 620, the container can be unloaded at a high speed, and the shuttles 300 and 400 are docked on the inner wall. Time can be minimized. Therefore, the shuttles 300 and 400 reciprocating between the mobile harbor 100 and the quay wall Q can be circulated at a high speed, thereby minimizing the time when the container ship 200 is anchored at sea. It can solve the problem of container ship accumulation in the port accordingly.

In addition, since the container can be directly unloaded from the shuttles 300 and 400 to the loading dock of the inner wall, the container can be transported to a specific storage location, and thus the problem of loading dock can also be solved.

8 is a view showing another example of the shuttle.

Referring to FIG. 8, an elevator 720 movable upward and downward to correspond to the height of the inner wall and a guide part 710 for guiding the movement of the elevator 720 may be formed at the rear of the shuttle 700. .

The elevator 720 may be formed in such a size that the transport vehicle 620 may stop in the traveling direction, and the guide part 710 may drive a winch or the like to move the elevator 720 in the vertical direction. Device may be included.

When the height of the deck of the shuttle 700 is higher than the quay wall Q, as shown in FIG. 7, the transport vehicle 620 uses the auxiliary means such as the ramp 630 to allow the shuttle 700 to carry out the shuttle 700. It may be allowed to drive between the deck and the quay of the car.

However, when the height of the deck of the shuttle is lower than the inner wall, it is difficult to use the lamp 630 provided on the inner wall Q side. In this case, the elevator 720 may allow the transport vehicle 620 to travel between the deck and the quay wall of the shuttle 700.

In detail, when the container is transported from the quay wall (Q) to the shuttle 700, when the elevator 720 is located at a height corresponding to the quay wall, the transport vehicle 620 moves above the elevator 720, When the elevator 720 is lowered to the deck height of the shuttle 700, the transport vehicle 620 may move to the deck to lower the pallet 610. On the contrary, when the container is transported from the shuttle 700 to the inner wall Q, when the transport vehicle 620 moves over the elevator 720 while holding the pallet 610, the elevator 720 moves to the inner wall. Elevated to the height, the transport vehicle 620 may move to the loading dock.

Since the appropriate shuttle can be selected and operated according to the height difference between the deck of the quay and the shuttle as described above, there is an advantage that the unloading method using the mobile harbor 100 can be used regardless of the height of the quay. That is, the height difference between the deck of the shuttle and the inner wall Q may be adjusted to correspond to each other by at least one of the ramp 630 and the lifting unit 720.

As described above as a specific embodiment of a mobile harbor according to an embodiment of the present invention, but this is only an example, the present invention is not limited to this, and should be construed as having the broadest range in accordance with the basic idea disclosed herein. . Those skilled in the art can easily change the material, size, etc. of each component according to the application field, and can be combined / substituted the disclosed embodiments to implement a pattern of a timeless shape, but this also does not depart from the scope of the present invention will be. It will be apparent to those skilled in the art that various changes and modifications may be readily made without departing from the spirit and scope of the invention as defined by the appended claims.
