Therefore, hereinafter, the marine cargo unloading system using the cargo container of the present invention will be described first by component, and the marine cargo unloading method using the cargo containers according to the first and second aspects will be described in detail.

Ship

In the present invention, the ship has a plurality of cargo holds separated by zones and a plurality of removable cargo gates.

The cargo hold generally has the meaning of a warehouse in which cargoes provided in a ship are loaded. However, in the present invention, the cargo hold has a meaning as a space in which cargo containers can be mounted, with a particular focus on cargo containers. This is because according to the present invention, all the loading and unloading operation of the marine cargo is made through the process of loading or unloading the cargo container to the cargo hold of the ship.

The vessel of the present invention, as shown in Figures 2 and 6, has a plurality of cargo holds separated by zone. The cargo hold size may vary depending on the size of the ship, the type of cargo and the ease of handling. If the longitudinal length of the cargo hold is excessively large, the ship will be unable to maintain the structural longitudinal strength of the hull, increasing the risk of safety accidents. In addition, if the size of the cargo bin is too large, a lot of efforts are required for the transportation and management of the cargo can not only have difficulty in practical use, but also can not load a variety of cargo to separate the loading efficiency. For example, for a container carrying a container, it is appropriate to determine the length of a 40-foot container in the longitudinal direction.

Therefore, the ship of the present invention has a plurality of cargo hold separated by zone, while also maintaining the structural strength of the hull, while allowing efficient and useful cargo container can be carried and managed.

And it is not particularly limited in the present invention how many cargo hold on the ship as long as it can maintain these technical advantages. For reference, according to an embodiment of the present invention, the ship is provided with four cargo holds (FIG. 2).

On the other hand, the side hull of the ship consists of a plurality of cargo hold gates that can be separated by zone. And the cargo hold gate is removable from the ship.

The cargo hold gate is a door that literally opens and closes the cargo hold. That is, the cargo hold is also opened and closed through the process of removing the cargo gate from the ship, the cargo can be opened and closed (loading and unloading) to the cargo hold as the cargo hold is opened and closed.

The cargo hold gate is attached in the form of being fitted to the side structure of the ship and has a fastening device for restraining the ship. The cargo hold gates have their own ballast tanks which allow for self-adjusting drafts.

The ship fills the ship's ballast tanks to separate the cargo hold gates and increases the draft of the ship. Then, water enters the cargo hold and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the ship releases the fastening device that has bound the cargo hold gate, the cargo hold gate is separated from the ship and floated.

In this case, it is desirable that ships have a separate control system to enable monitoring of ballast loading and integrated control.

In addition, ships are preferably provided with longitudinal reinforcements for each cargo hold so as to maintain the hull longitudinal strength even if the cargo hold gates are separated (Fig. 2). These longitudinal reinforcements are removed during the loading and unloading of the cargo containers and the loading of cargo containers. And it is designed to be reinstalled after the unloading is completed. That is, the longitudinal reinforcement is designed to be removable to the cargo hold.

Cargo container

Cargo containers manufactured according to the shape of the cargo hold are loaded and unloaded into the ship through the process of loading and unloading the cargo hold of the ship.

Cargo container is preferably designed to have a size and weight that is easy to handle, but considering the purpose of the present invention to increase the efficiency of unloading through the rapid loading and unloading of the marine cargo a plurality of cargo of too small size It is better to avoid loading multiple bins into one hold. This is because it is not much different from the case of loading or unloading containers one by one with respect to the existing container leased line. For reference, according to an embodiment of the present invention, the ship is provided with four cargo holds, and cargo containers are provided with a total of four to be loaded one by one in each cargo hold (FIG. 2). Figure 5 shows a super large cargo container for container shipping according to an embodiment of the present invention. In FIG. 5, the cargo bin has a cuboid shaped body for effective space utilization for container loading. Cargo barrels have their own ballast tanks, which allow for self-adjustment of drafts and control systems for temperature, humidity, etc., to maintain the condition of the cargo contained within the bins.

In the present invention, if the cargo container is used in particular for the shipment of the container, it is preferable to prevent the lashing problem by installing a container fixing device inside the cargo container. In addition, when stacking the container five or more stages, it is preferable to prevent damage to the container by providing an intermediate reinforcement plate.

Of course, the cargo container of the present invention is not only used for the shipment of the container. In the present invention, since the loading and unloading of the cargo (that is, the movement of the cargo) is made in the state containing the cargo in the cargo container, the cargo container of the present invention is effective for transporting bulk cargo as well as containers, It also works for transportation. In addition, it can be used as a tanker ship, such as a chemical carrier ship by loading liquid cargo in the cargo container, and also can be used as a general cargo ship because it can load different types of cargo for each cargo area. In addition, very large cargoes can be transported by structural reinforcement of cargo containers.

Maritime Terminal

Maritime terminals assist in the replacement of cargo hold gates and cargo vessels at sea.

The marine terminal is a kind of floating self-moving terminal, as shown in FIGS. 3 and 4. Therefore, the sea terminal has its own ballast tank, which can adjust its own draft, and its own propeller can move itself.

The characteristic of the marine terminal in the present invention is that the overall structure or function is similar to that of the ship. That is, the maritime terminal has a plurality of cargo hold separated by zone like a ship and a plurality of removable cargo hold gates. However, the number of cargo holds at sea terminals is not necessarily the same as for ships. For reference, according to an embodiment of the present invention, the maritime terminal is provided with two cargo holds (FIG. 3).

Hereinafter, the process of helping the marine terminal to replace the cargo hold gate and the cargo container of the vessel at sea with reference to Figures 3 and 4.

A ship carrying a cargo container containing cargo enters the port and fills the ship's ballast tanks with water to remove the cargo hold gates and increases the draft. Then, water enters the cargo hold and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, if the ship releases the hydraulic pressure that was bound to the cargo hold gate is the cargo hold gate is separated from the ship to float. And when the ship unlocks the cargo container, the cargo container is separated from the ship and floated.

Meanwhile, the sea terminal arrives on the side of the ship during this process. In this case, the cargo hold at the sea terminal is empty. At this time, the harbor on one side of the ship, the maritime terminal should be located on the other side (Fig. 3, 4). This is to allow for the replacement of cargo containers in stages between ports, ships and sea terminals. More details on this will be described later.

The sea terminal increases the draft of the sea terminal by filling the ballast tanks of the sea terminal to separate the cargo hold gates. In this case, it is desirable that the maritime terminal be equipped with a separate control system that enables monitoring and integrated control of ballast loading status, as with ships. Then, water enters the cargo hold of the sea terminal and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the marine terminal releases the hydraulic pressure that bound the cargo hold gate, the cargo hold gate is separated from the marine terminal and floated.

At this time, the sea terminal is separated from the ship by means of ropes and winches, and the floating cargo container is pulled into the cargo hold of the sea terminal and loaded and restrained by the locking device. Also, by using means such as ropes and winches, the cargo terminal gate of the floating marine terminal, which had been separated from the marine terminal a while ago, is pulled into the cargo terminal of the marine terminal and restrained by applying hydraulic pressure.

Through the above process, the cargo container loaded on the ship moved to the sea terminal immediately from the sea, and the cargo hold of the ship is empty.

Harbor

At this time, the cargo container containing the new cargo in the harbor is in the state of being put down by the elevator or the like. In this case, the cargo container is confined to the port by the locking device.

In general, a port is a geographical nodule linking land and sea activities. It is a part of the sea level where facilities can be securely anchored and loaded and unloaded by passengers and cargo at the seaside, which is covered with natural terrain or artificial structures. In particular, the port of the present invention should be provided with a moving means of a cargo container, such as an elevator.

In other words, by installing a large elevator on the quay of the harbor, the cargo can be transported from the land to the sea, can be lifted from the sea to the land (Fig. 4). In addition, it is desirable to minimize elevator work by utilizing a conveyor system (or transporter) for cargo transportation on land.

When a cargo container on board a vessel is moved to a sea terminal, the port unlocks a new container. The cargo can then float at sea. At this time, the ship is separated from the port by means of ropes and winches, and the floating cargo container is pulled and loaded into the cargo hold of the ship and restrained by the locking device. Also, by using means such as ropes and winches, the cargo hold gate of the ship, which has been separated from the ship just before, is drawn to the cargo hold of the ship and restrained by applying hydraulic pressure.

Through the above process, the cargo container containing the new cargo waiting in the port was moved directly from the sea to the ship. And in this process, it does not take much time for the ship to load (load) new cargo in the port.

After the ship with the new cargo departs (in this case, the ship discharges the ballast to reduce the draft of the vessel and floats to the surface), the sea terminal, which has carried the cargo container loaded on the vessel, is docked at the port and then again. Float the cargo container in the harbor. Then, the port is pulled into the port by means of ropes and winches and then moved to the land using a lift or the like.

Through the above process, the cargo container loaded by the ship entering the port finally moved to the port. And in this process, it does not take much time for the ship to unload cargo into the port.

According to the invention Cargo container  Marine cargo unloading method using: first type

First, the present invention, S100 step of placing a cargo in a new cargo container before the ship arrives at the port; Step S200 in which a ship carrying a cargo container containing cargo arrives at the port, the maritime terminal hands over the cargo container of the vessel at sea, and the vessel takes over a new cargo container from the harbor; After the ship has received a new cargo ship departs the marine terminal receiving the cargo container of the ship unloads cargo containers in the port; S300 provides a marine cargo loading method using a cargo container including a. Hereinafter, each step will be described in detail.

One. S100  step

Step S100 includes the following steps S101 to S104.

(1) Step S101 : Put the cargo in a new cargo container before the ship arrives at the port. Here, a new cargo container corresponds to a cargo container loaded by a ship that will arrive at the port after a while. Cargo enters.

(2) Step S102 : move the new container to the port. In this case, a conveyor system (or transporter) may be used to transport cargo containers on land.

(3) Step S103 : A new container is installed in the port lift and flooded with the loading draft. In other words, using a lift installed on the harbor quay, a new cargo container is laid down from the land to the sea (Fig. 4). At this time, the loading draft refers to the sea level depth of the locked state so that the new container can float in the sea floating (Fig. 4).

(4) Step S104 : The sea terminal is flooded with unloading draft to remove the cargo hold gate. The sea terminal increases the draft of the sea terminal by filling the ballast tanks of the sea terminal to separate the cargo hold gates. Then, water enters the cargo hold of the sea terminal and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the marine terminal releases the hydraulic pressure that bound the cargo hold gate, the cargo hold gate is separated from the marine terminal and floated. As a result, the sea terminal is ready to take over the cargo container containing the cargo from the ship that will arrive at the port later.

2. S200  step

Step S200 includes the following steps S201 to S210.

(1) Step S201 : A ship carrying a cargo container containing cargo arrives at the port and floods with unloading draft. At this time, the unloading draft refers to the sea level depth of the locked state so that the cargo container loaded by the vessel can float floating on the sea. On the other hand, in this step, the harbor on one side of the ship, the maritime terminal should be located on the opposite side (Fig. 3, 4). This is to allow for the replacement of cargo containers in stages between ports, ships and sea terminals.

(2) Step S202 : The ship separates the first cargo hold gate of the left and right portboards. A ship carrying a cargo container containing cargo enters the port and fills the ship's ballast tanks with water to remove the cargo hold gates and increases the draft. Then, water enters the cargo hold and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the ship releases the hydraulic pressure that bound the first cargo hold gate, the first cargo hold gate is separated from the ship and floated.

(3) Step S203 : Remove longitudinal reinforcement of the first cargo hold of the ship.

(4) Step S204 : The ship separates the cargo container from the first cargo hold. If the cargo lock is unlocked while the ship is locked by the unloading draft, the cargo hold of the first cargo hold is separated from the ship and floated. In this case, the cargo container may be more easily separated from the ship by discharging its ballast to the outside.

(5) Step S205 : The cargo container is moved to the cargo hold of the sea terminal and fixed. The sea terminal is separated from the ship by means of ropes and winches, and the floating cargo container is pulled into the cargo hold of the sea terminal and loaded and restrained by the locking device. Through the above process, the cargo container of the first cargo hold loaded on the ship is moved from the sea immediately to the sea terminal, and the first cargo hold of the ship is empty.

(6) Step S206 : A new cargo container installed at the port is moved to the first cargo hold of the ship and fixed. When the cargo hold of the first cargo hold on board a vessel is moved to the sea terminal, the port unlocks the new cargo hold. The cargo can then float at sea. At this time, the ship is separated from the port by means of ropes and winches, and the floating cargo container is pulled and loaded into the first cargo hold of the ship and restrained by the locking device. Through the above process, a new cargo tank in the port was moved from the sea immediately to the ship, completing the shipment of cargo to the first cargo hold of the ship.

(7) Step S207 : Install the longitudinal reinforcement of the first cargo hold of the ship.

(8) Step S208 : The ship installs the first cargo hold gate in the port. The ship is separated from the ship by means of ropes and winches and pulls the floating first cargo hold gate to the first cargo hold of the ship and restrains it by applying hydraulic pressure.

(9) Step S209 : The ship repeats the steps S202 to S208 for the second and subsequent cargo holds to complete the loading of all cargo holds.

(10) Step S210 : A ship that has completed the loading of all cargo holds floats and sails. In this case, the ship discharges ballast to reduce the draft of the ship and rise to the surface. As a result, the vessel does not have to stay in the port for a long time for loading and unloading operations, thereby reducing the logistics cost.

3. S300  step

Step S300 includes the following steps S301 to S304.

(1) Step S301 : The marine terminal installs a cargo hold gate. The sea terminal, which has moved all the cargo containers from the ship, is separated from the sea terminal by a rope or winch, and pulls the cargo hold gate of the floating sea terminal into the cargo hold of the sea terminal and restrains it by applying hydraulic pressure. .

(2) Step S302 : The sea terminal rises to the draft and moves to the port. In this case, the sea terminal discharges the ballast to reduce the draft of the sea terminal and rise to the surface.

(3) Step S303 : The cargo container is installed in the harbor lift and moved to the land. The sea terminal docks at the port and then floats the cargo container again. Then, the port is pulled into the port by means of ropes and winches and then moved to the land using a lift or the like. Through the above process, the cargo container loaded by the ship arriving at the port finally moved to the port.

(4) Step S304 : Complete the unloading of the cargo contained in the cargo container. According to the present invention as described above, in the cargo container manufactured according to the shape of the cargo hold of the ship in advance, the cargo arrives at the port when the ship arrives at the port immediately after replacing the cargo hold gate of the ship unloading by installing the cargo container on the ship It can be seen that the efficiency of the work can be significantly increased.

According to the invention Cargo container  Marine cargo unloading method using: second type

Meanwhile, the present invention may be implemented as in the following second form. That is, the present invention, the S1 step that the sea terminal is submerged in the unloading draft to separate the cargo hold gate; S2 step of submerged in the unloading draft after the ship loaded with the cargo container containing the cargo arrives at the port; Step S3 of the ship separating the first cargo hold gate of the left and right port; Step S4 of the ship separating the cargo container of the first cargo hold; Step S5 that the cargo container is fixed by moving to the cargo hold of the sea terminal; S6 step that the ship installs the first cargo hold gate of the left and right port; S7 step in which the ship completes the movement of all the cargo hold by repeating the process of steps S3 to S6 for the second and subsequent cargo hold; Step S8, in which the vessel floats and moves at the operating draft; Step S9, wherein the marine terminal installs the cargo hold gate; A marine cargo unloading method using a cargo container, including; S10 step in which the maritime terminal floats and moves to the operating draft. Hereinafter, each step will be described in detail.

(1) Step S1 : The sea terminal is flooded with the unloading draft to remove the cargo hold gate. At this time, the unloading draft refers to the sea level depth of the locked state so that the cargo container to be loaded by the vessel can float floating on the sea. The sea terminal increases the draft of the sea terminal by filling the ballast tanks of the sea terminal to separate the cargo hold gates. Then, water enters the cargo hold of the sea terminal and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the marine terminal releases the hydraulic pressure that bound the cargo hold gate, the cargo hold gate is separated from the marine terminal and floated. As a result, the sea terminal is ready to take over the cargo container containing the cargo from the ship that will arrive at the port later.

(2) S2 stage: A ship carrying a cargo container containing cargo arrives at the port and floods with unloading draft. At this time, the unloading draft is the same as the meaning in the step S1.

(3) S3 stage: The ship removes the first cargo hold gate in the left and right port. A ship carrying a cargo container containing cargo enters the port and fills the ship's ballast tanks with water to remove the cargo hold gates and increases the draft. Then, water enters the cargo hold and the pressure (water pressure) inside and outside the cargo hold coincides. At this time, when the ship releases the hydraulic pressure that bound the first cargo hold gate, the first cargo hold gate is separated from the ship and floated.

(4) Step S4 : The ship removes the cargo container from the first cargo hold. If the cargo lock is unlocked while the ship is locked by the unloading draft, the cargo hold of the first cargo hold is separated from the ship and floated. In this case, the cargo container may be more easily separated from the ship by discharging its ballast to the outside.

(5) Step S5 : Cargo container is moved to the cargo hold of the sea terminal and fixed. The sea terminal is separated from the ship by means of ropes and winches, and the floating cargo container is pulled into the cargo hold of the sea terminal and loaded and restrained by the locking device. Through the above process, the cargo container of the first cargo hold loaded on the ship is moved from the sea immediately to the sea terminal, and the first cargo hold of the ship is empty.

(6) S6 stage: The ship installs the first cargo hold gate in the port. The ship is separated from the ship by means of ropes and winches and pulls the floating first cargo hold gate to the first cargo hold of the ship and restrains it by applying hydraulic pressure.

(7) Step S7 : The ship repeats the steps S3 to S6 for the second and subsequent cargo holds to complete the movement of all cargo holds.

(8) S8 stage: The ship rises to the draft, and moves to ship or repair the next cargo. In this case, the ship discharges ballast to reduce the draft of the ship and rise to the surface. As a result, the vessel does not have to stay in the port for long time for unloading operation, thereby reducing the logistics cost.

(9) Step S9 : The sea terminal installs the cargo hold gate. The sea terminal, which has moved all the cargo containers from the ship, is separated from the sea terminal by a rope or winch, and pulls the cargo hold gate of the floating sea terminal into the cargo hold of the sea terminal and restrains it by applying hydraulic pressure. .

(10) Step S10 : The sea terminal rises to the draft and moves to the port. In this case, the sea terminal discharges the ballast to reduce the draft of the sea terminal and rise to the surface. The sea terminal, which takes over the cargo container loaded on the ship, docks at the port and then moves the cargo container to the port. Through the above process, the cargo container loaded by the ship entering the port finally moved to the port. And in this process, it does not take much time for the ship to unload cargo into the port. That is, according to the present invention, when a vessel carrying a cargo container containing cargo enters the port, the sea terminal receives the vessel's cargo container immediately from the sea and unloads it into the port, thereby ensuring the safety and It can be seen that the speed can be increased.
