Description

  The present invention is a cargo sea relay floating body, cargo sea relay system, cargo sea transport system, which can optimize the environmental measures of a ship used when shipping cargo by sea through both environmentally regulated sea areas and non-environmentally regulated sea areas, The present invention relates to a cargo sea relay method and a cargo sea transportation method.

  At present, in the shipping industry, environmental regulations have been strengthened globally, and it is necessary for all ships to comply with these environmental regulations. In particular, compared with general sea areas, environmental regulations (ECA: Emission). In the Control Area), stricter regulations are required, and all ships that navigate the environmental regulation area are high-environment countermeasure specifications that comply with the regulations.

  The contents of this high environmental measure specification include regulations on the reduction of carbon dioxide, the treatment of ballast water, and the reduction of NOx and SOx emissions, and more stringent regulations will be implemented in the future.

  In the prior art, for example, as shown in FIG. 6, the cargo marine transportation system 60 includes a first environmental regulation region R1, a non-environmental regulation region Rf such as the high seas, and a second environmental regulation region R2. The freight is transported on the route LX by the same ship 2X. Therefore, all of the vessels 2X that navigate the route LX have specifications corresponding to the environmental regulations in the first environmental regulation region R1, and the second environmental regulations. If the environmental regulation in the region R2 is an environmental regulation different from the environmental regulation in the first environmental regulation region R1, it is necessary to make the specification corresponding to the environmental regulation in the second environmental regulation region R2.

  In this connection, in order to respond to the SOx emission control area, which is one of such environmental regulations, in a ship passing through a fuel control area where low sulfur fuel must be used, The surrounding area is set as an alarm area, and a pre-warning area is set around the alarm area. When the ship reaches the pre-warning area, a warning is issued to prepare for fuel switching, and the ship reaches the alarm area. In such a case, an automatic fuel switching system in a ship has been proposed in which an alarm for fuel switching is issued and a fuel switching operation is automatically performed (see, for example, Patent Document 1).

  However, the installation of such an automatic fuel switching system is premised on the installation of a storage tank for general fuel and a storage tank for low-sulfur fuel, and the installation of the respective fuel supply systems. As it goes on, there is a problem that large remodeling is required and the cost becomes high.

  On the other hand, there has been proposed a slurry handling facility using a slurry ship serving as a relay base for loading an object to be transported from a harbor without storage facilities and loading facilities (for example, see Patent Document 2).

  In this slurry handling facility, a slurry ship moored offshore was placed next to the slurry ship, a crane with a grab and a belt conveyor device capable of carrying the dewatered material after slurry dehydration from the warehouse, and the slurry ship. A loading belt conveyor device capable of loading an object to be transported on a transport ship is provided.

  As a result, it can be used as a transit base for loading transported objects on a transport ship without constructing harbor facilities and storage facilities at ports that cannot be berthed, and the cost can be reduced compared to the construction cost of the facilities, and it is easy. Therefore, after the mining site has been dug out, it can be moored offshore at another mining site and used efficiently.

  However, in this slurry handling facility, the slurry is transferred to the slurry of the slurry cargo ship by the slurry handling device, the slurry is dehydrated and stored in the hold, and the dehydrated material to be transported is stored in the grab crane and belt. A conveyor device and a belt conveyor device for loading are put into the hold of the transport ship from the warehouse and do not relay general cargo handling.

  The present invention has been made in view of the above situation, and its purpose is that all ships can pass through the environmental control area because it passes through the environmental control area provided in a part of the route during operation. Instead of ships with high environmental regulations, only a part of the ships are allowed to pass high environmental regulations and pass through the environmental regulations area, and other ships are passed through the non-environmental regulations area as non-environmentally restricted area specifications. Accordingly, it is an object of the present invention to provide a cargo sea relay floating body, a cargo sea relay system, a cargo sea transport system, a cargo sea relay method, and a cargo sea transport method, which can keep ship procurement costs low in a fleet plan.

  The cargo sea relay floating body for achieving the above-mentioned object includes a cargo hold, a ship locking mechanism for anchoring or mooring a ship, the ship that is connected or moored to the ship locking mechanism, and the ship A cargo handling mechanism for transferring cargo to and from the cargo hold, a position holding mechanism, a posture control mechanism for controlling the posture, a power supply mechanism for operating the cargo handling mechanism and the posture control mechanism, and movement It is configured without a propulsion device.

  According to this configuration, the cargo can be transported to the cargo hold of the cargo maritime relay floating body from the first ship that is engaged or moored by the ship locking mechanism in the cargo maritime relay floating body. In addition, since the cargo can be transferred from the cargo hold to the second vessel where the cargo is berthed or moored, the cargo is transferred from one vessel to the other vessel at sea. It can be transshipped using the floating body for cargo sea relay as a relay base.

  In the above freighter for marine cargo relay, the mooring device or position propulsion device is provided as the position holding mechanism, and the mooring device or position is provided with a ballast tank and a ballast water moving system as the attitude control mechanism. The holding propulsion device prevents the cargo floating relay body from drifting due to tidal currents and winds, and also moves the ballast water between the ballast tanks. Since the posture change of the floating body can be easily returned to the original state, cargo handling performed between the cargo floating relay body and the ship can be promoted.

  In the cargo sea relay floating body described above, when the ship includes a ballast water tank and a ballast water treatment device for storing the ballast water of the ship that is in contact with or moored with the ship locking mechanism, the cargo sea relay floating body Since it becomes possible to store and process the ballast water of the vessels that have been berthed or moored, it is not necessary to install a ballast water treatment device on these vessels, and accordingly, these vessels can be made low-cost vessels. .

  And the cargo sea relay system for achieving the above-mentioned object moves cargo from the second ship to the cargo sea relay floating body, and transfers a part of the cargo from the cargo sea relay floating body to the second Moving to the first ship corresponding to environmental regulations higher than that of the ship, moving the cargo from the first ship or the third ship to the cargo sea relay floating body, from the cargo sea relay floating body, The second ship or the fourth ship that corresponds to environmental regulations lower than those of the first ship or the third ship that are more than the cargo transferred at a time from the first ship or the third ship. Configured to move to the ship.

  According to the configuration of this system, the cargo marine relay floating body is located and held in a non-environmentally restricted area outside the environment-regulated area near the port in the environment-regulated area. Non-environmental, second or third ship that meets high environmental regulations to navigate the route including the environmental regulation area between floating bodies for cargo sea relay outside the regulation area, cargo sea relay floating body, high seas and non-environment Ports in the environmental control area and non-environment by using the first ship or the fourth ship that correspond to low environmental regulations, in other words, that do not correspond to high environmental regulations. It will be possible to carry out marine transportation on the route that spans both the restricted areas and while implementing environmental measures in accordance with the actual situation in each area.

  In addition, a freight marine transportation system for achieving the above object includes a first route including a preset environmental regulation area between the first port and the first freight marine relay floating body. Transported by a ship belonging to a first fleet composed of environmentally compliant ships capable of navigating the restricted area, and the second route between the cargo sea relay floating body and the second port is the first It is constituted so that it may be transported by a ship belonging to the second fleet constituted by a ship corresponding to environmental regulations lower than that of the fleet.

  According to the configuration of this system, the cargo marine relay floating body is disposed and held in the non-environmental regulation area, and the first marine relay relay floating body between the first port and the cargo marine relay floating body is included. The environment of the first fleet ship that complies with the high environmental regulations navigating the route, and the freight marine relay floating body located near the first port and in the non-environmentally restricted area, between the high seas and the second port. It is possible to properly use the ship of the second fleet that navigates the second route that does not include the restricted area.

  By properly using this, the ship in the first fleet that passes through the environmental regulation area is transported at a medium distance, and thus can be reduced in size as compared with the ship in the second fleet. Further, the ship of the second fleet that does not pass through the environmental regulation area can be made larger than the ship of the first fleet.

  As a result, in operation, some ships do not become high environmental regulation specification ships that can pass the environmental regulation area because they pass the environmental regulation area provided in a part of the route. Only the non-environmentally restricted area can be passed as a ship with a non-environmentally restricted area specification, and the ship procurement cost can be reduced in the fleet plan. Can be suppressed.

  In the above freight marine transportation system, the following effects can be obtained when the loading load of the ship belonging to the second fleet is made larger than that of the ship belonging to the first fleet.

  By making the ship of the first fleet that passes through the environmental regulation area a medium-sized ship with a smaller load capacity, it is possible to make a more flexible transportation plan than a transportation plan with only a large ship with a larger load capacity. Thus, fuel costs can be improved through operation. Also, in responding to environmental regulations, medium-sized ships calling at the port can be handled with smaller equipment than large ships, and costs required to comply with strict environmental regulations can be kept low.

  Further, by making the ship of the second fleet that does not pass through the environmental regulation area a large ship, it is only necessary to deal with the environmental regulation in the general sea area in response to the environmental regulation, so that the cost can be saved.

  Alternatively, a cargo marine transportation system for achieving the above object includes a first route including a preset first environmental regulation area between the first port and the first cargo marine relay floating body. , Transported by a ship belonging to a first fleet composed of environmentally compliant ships capable of navigating the first environmental regulation area, and the first cargo sea relay floating body and the second cargo sea relay floating body, The second route between the second fleet is transported by a ship belonging to the second fleet composed of ships corresponding to environmental regulations lower than the ship of the first fleet, The third route including the second environmental regulation area set in advance between the two ports belongs to the third fleet composed of environmental countermeasure specification vessels capable of navigating the second environmental regulation area. Configured to be transported by ship.

A ship in the second fleet and a ship in the third fleet corresponding to high environmental regulations that travel on the third route including the second environmental regulation area can be properly used.

  As a result, not all ships are made high-environmentally regulated ships that can pass through the environment-regulated area because they pass through the environment-regulated area provided in a part of the route in operation, and the ships of the first fleet and Only the ship of the 3rd fleet can be made to be a ship with high environmental regulation specifications and pass through the environment regulation area, and the ship of the second fleet can be passed through only the non-environmental regulation area as a ship of non-environmental regulation area specification. Therefore, ship procurement costs can be kept low in fleet planning.

  In the above freight maritime transportation system, the load capacity of the ship belonging to the second fleet is configured to be larger than the ship belonging to the first fleet, and more than the ship belonging to the third fleet, The following effects can be achieved by increasing the loading amount of the ship belonging to the second fleet.

  In other words, by making the ships of the first and third fleets medium-sized ships with a smaller load capacity, it is possible to make a flexible transportation plan as compared with a transportation plan using only a large ship with a larger load capacity. Therefore, the fuel cost can be improved by operation. In addition, costs required for complying with strict environmental regulations can be kept low. In addition, by making the ship of the second fleet a large ship, it is only necessary to comply with environmental regulations in the general sea area, so it is possible to save costs and to make the ship large in size that is not subject to port size restrictions. As a result, transportation efficiency can be increased.

  In the cargo sea relay method for achieving the above object, the cargo is transferred from the second ship to the cargo sea relay floating body, and a part of the cargo is transferred from the cargo sea relay floating body to the second ship. Moving to the first ship corresponding to environmental regulations higher than that of the ship, moving the cargo from the first ship or the third ship to the cargo sea relay floating body, from the cargo sea relay floating body, The second ship or the fourth ship that corresponds to environmental regulations lower than those of the first ship or the third ship that are more than the cargo transferred at a time from the first ship or the third ship. It is a method characterized by moving to a ship.

  In addition, the freight marine transportation method for achieving the above object is characterized in that the first route including a preset environmental regulation area between the first port and the first freight marine relay body is the environment. Transported by a ship belonging to a first fleet composed of environmentally compliant ships capable of navigating the restricted area, and the second route between the cargo sea relay floating body and the second port is the first It is a method characterized by transporting with a ship belonging to the second fleet composed of ships corresponding to environmental regulations lower than those of the fleet.

  Alternatively, in the freight marine transportation method for achieving the above object, the first route including the first environmental regulation region set in advance between the first port and the first freight marine relay floating body is: , Transported by a ship belonging to a first fleet composed of environmentally compliant ships capable of navigating the first environmental regulation area, and the first cargo sea relay floating body and the second cargo sea relay floating body, The second route between the second fleet is transported by a ship belonging to the second fleet composed of ships corresponding to environmental regulations lower than the ship of the first fleet, The third route including the second environmental regulation area set in advance between the two ports belongs to the third fleet composed of environmental countermeasure specification vessels capable of navigating the second environmental regulation area. It is a method characterized by transporting by ship.

  According to these methods, the same effects as those of the cargo maritime relay system and the cargo maritime transportation system corresponding to the respective methods can be obtained.

  According to the cargo sea relay floating body, cargo sea relay system, cargo sea transport system, cargo sea relay method, and cargo sea transport method according to the present invention, it passes through an environmental regulation area provided in a part of the route during operation. For this reason, not all ships are made to be highly environmentally compliant ships that can pass through the environmental control area, but only some ships are allowed to pass the environmental control area in response to high environmental regulations and other ships are not Since the ship of the environment regulation area specification can pass only the non-environment regulation area, the ship procurement cost can be kept low in the fleet plan.

  In addition, this makes it possible to further increase the size of the ship and to develop and design a ship with various environmentally-friendly specifications, and to provide a ship in accordance with the actual situation that environmental regulations vary from sea area to sea area.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a cargo sea relay floating body, a cargo sea relay system, a cargo sea transport system, a cargo sea relay method, and a cargo sea transport method according to embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1 and FIG. 2, a cargo marine relay floating body 10 according to an embodiment of the present invention includes a cargo hold 11, a ship locking mechanism for connecting or mooring ships 1, 2, A cargo handling mechanism that transports cargo between the ships 1 and 2 and the cargo hold 11 that are connected or moored to the stopping mechanism, a position holding mechanism, a posture control mechanism that controls the posture, a cargo handling mechanism, and a posture control mechanism. It is configured with a power supply mechanism for operating, but is configured without a propulsion device for movement.

  The cargo hold 11 is for temporarily storing one type or a plurality of types of cargo to be transported by sea transportation, and includes a plurality of cargo holds 11 so that they can be stored according to the type of cargo. Further, the ship locking mechanism is constituted by a mooring column 12 for anchoring or mooring the ships 1 and 2 or a fender made of a rubber material. The ships 1 and 2 are moored on the floating body 10 by taking, for example, mooring lines 1 a and 2 a from the mooring column 12.

These drive sources require explosion-proof specifications. Drive a crane or pump

  Furthermore, it comprises the ballast water tanks 17 and 18 for ships which store the ballast water of the ships 1 and 2 to be engaged or moored, and a ballast water treatment device 19. The ship ballast water tanks 17 and 18 are different tanks according to the routes of the ships 1 and 2. For example, ballast water of a ship 1 navigating on the high seas is stored in a ship ballast water tank 17 close to the place where the ship 1 is moored, sails along the coast, enters a port, and so on. The ballast water of the ship 2 entering the environmental regulation area is stored in a ship ballast water tank 18 close to a place where the ship 2 is moored.

  The ballast water separately stored in the marine ballast water tanks 17 and 18 is subjected to another ballast water treatment device 19 by killing microorganisms or the like by filtering, ozone treatment or chemical treatment, if necessary. Stored in marine ballast water tanks 17 and 18. The ships 1 and 2 are supplied with ballast water from the corresponding ship ballast water tanks 17 and 18 as necessary.

  This eliminates the need to mount the ballast water treatment device 19 on these ships 1 and 2 so as to store and process the ballast water of the ships 1 and 2 that are in contact with or moored to the cargo floating relay 10. Therefore, it will be a low-cost ship.

  According to the cargo marine relay floating body 10 having the above-described configuration, cargo is loaded into the cargo hold 11 of the cargo marine relay floating body 10 from the first ship 1 (or the ship 2) that is in contact with or moored by the ship locking mechanism. The cargo can be transported using a cargo handling mechanism such as a crane 13, and the cargo can be transported from the cargo hold 11 to the second ship 2 (or the ship 1) where the cargo is berthed or moored. Thus, the cargo can be transferred from the ship 1 (or the ship 2) to another ship 2 (or the ship 1), and can be transshipped.

  Next, the cargo sea relay system and the cargo sea relay method according to the embodiment of the present invention will be described. As shown in FIG. 3, the cargo marine relay system 30 includes a second ship S2 and a fourth ship S4 that do not comply with high environmental regulations, and a first ship S1 that supports high environmental regulations. This is a system for transferring cargo to and from the third ship S3.

  The cargo marine relay system 30 moves cargo from the second ship S2 to the cargo marine relay floating body 10, and moves a part of the cargo from the cargo marine relay floating body 10 to the first ship S1. Configured to do. At the same time, the cargo is moved from the first marine vessel S1 or the third marine vessel S3 to the cargo marine relay floating body 10, and is transferred from the cargo marine transit relay body 10 from the first marine vessel S1 or the third marine vessel S3 at a time. It is configured to move more cargo than the cargo that has been sent to the second vessel S2 or the fourth vessel S4.

  Similarly, in the cargo sea relay method of this embodiment, cargo is transferred from the second ship S2 to the cargo sea relay floating body 10, and a part of the cargo is transferred from the cargo sea relay floating body 10 to the The first ship S1 or the third ship S3 moves the cargo to the cargo marine relay floating body 10, and the cargo marine relay floating body 10 transfers the first ship S1 or the third ship S1. This is a method characterized in that more cargo than the cargo transferred at one time from the vessel S3 is moved to the second vessel S2 or the fourth vessel S4.

  According to the cargo marine relay system 30 and the cargo marine relay method, the cargo marine relay floating body 10 is placed in a non-environmentally restricted area near the port in the environment regulated area and held in position. The first ship S1 or the third ship corresponding to high environmental regulations for navigating the route including the environmental regulation area between the port in the environmental regulation area and the cargo floating relay body 10 outside the environmental regulation area. Corresponding to low environmental regulations, in other words, the second ship S2 or the fourth S4 that does not correspond to high environmental regulations, and that uses S3 and the non-environmentally restricted areas such as the cargo sea relay floating body 10 and the high seas. By properly using the ship S4, it is possible to carry out marine transportation while taking environmental measures in accordance with the actual situation in each area on the route that spans both the port in the environmental regulation area and the non-environment regulation area. .

The included first route L1 is transported by a ship 1 belonging to a first fleet composed of environmentally compliant ships capable of navigating the first environmental regulation region R1, and the cargo sea relay floating body 10A and the second port. The second route L2 to and from P2 is a method characterized by transporting with a ship 2 belonging to a second fleet composed of ships corresponding to environmental regulations lower than the ship 1 of the first fleet. .

  Furthermore, the load amount of the ship 2 belonging to the second fleet is made larger than that of the ship 1 belonging to the first fleet. Thereby, by making the ship 1 of the first fleet passing through the first environmental regulation region R1 into a medium-sized ship having a smaller load capacity, it is more flexible than a transportation plan using only a large ship having a larger load capacity. It becomes possible to make a transportation plan and to improve the fuel cost by operation. Also, in response to environmental regulations, the medium-sized ship 1 that calls at the first port P1 can be handled with smaller equipment than the large-sized ship 2, and the cost required for complying with strict environmental regulations. It can be kept low.

  Further, by making the ship 2 of the second fleet that does not pass through the first environmental regulation area R1 into a large ship, it is only necessary to deal with the environmental regulation of the general sea area Rf in response to the environmental regulation, thus saving costs. it can.

  According to the cargo maritime transportation system 40 and the cargo maritime transportation method of the first embodiment, the cargo maritime relay floating body 10A is arranged and held in the non-environmental regulation region Rf, and the first port P1 is maintained. A ship 1 of the first fleet corresponding to high environmental regulations that navigate the first channel L1 including the first environmental regulation region R1 between the floating body 10A and the cargo floating relay 10A, and the first port P1. A second freight seaway relay body 10A provided in the non-environmentally restricted area Rf and the second route L2 between the high seas and the second port P2 that does not include the first environment restricted area R1. It can be used properly for ships 2 in the fleet.

  By properly using this, the ship 1 of the first fleet that passes through the first environmental regulation region R1 is transported at a medium distance, and therefore can be reduced in size as compared with the ship 2 of the second fleet. Further, the ship 2 of the second fleet that does not pass through the first environmental regulation region R1 can be made larger than the ship 1 of the first fleet.

  And by this, all the ships 1 and 2 can pass 1st environmental control area | region R1 because it passes 1st environmental control area | region R1 provided in a part of route (L1 + L2) in operation. Not only ships with high environmental regulation specifications, but only a part of the ships 1 are made to comply with high environmental regulations and pass through the first environmental regulation area R1, and the other ships 2 are non-environmental regulation area specification ships. Since only the non-environmentally restricted area Rf such as can be passed, the ship procurement cost can be kept low in the fleet plan.

  Next, the cargo sea transportation system 50 and the cargo sea transportation method according to the second embodiment of the present invention will be described. As shown in FIG. 5, the cargo maritime transport system 50 includes a first environmental regulation region R1 that is set in advance between the first port P1 and the first cargo maritime relay floating body 10A. The channel L1 is configured to be transported by a ship 1 belonging to a first fleet that is configured by an environment countermeasure specification ship capable of navigating the first environment regulation region R1.

The included first route L1 is transported by the ship 1 belonging to the first fleet composed of the environmentally compliant ship capable of navigating the first environmental regulation region R1, and the first cargo-to-marine relay floating body 10A and the first The second route L2 between the cargo freight marine relay floating body 10B is transported by the ship 2 belonging to the second fleet composed of ships corresponding to environmental regulations lower than the ship 1 of the first fleet, The third route L3 including the preset second environmental regulation region R2 between the second cargo marine relay floating body 10B and the second port P2 can navigate the second environmental regulation region R2. It is transported by a ship 3 belonging to a third fleet composed of environmentally compliant ships. It is that way.

  Furthermore, it is configured to have a larger load capacity of the ship 2 belonging to the second fleet than the ship 1 belonging to the first fleet, and belongs to the second fleet rather than the ship 3 belonging to the third fleet. The loading load amount of the ship 2 is increased. As a result, by making the ships 1 and 3 of the first and third fleets medium-sized ships, it becomes possible to make a flexible transportation plan as compared to a transportation plan using only a large ship, and the fuel cost due to operation. Can be improved. In addition, costs required for complying with strict environmental regulations can be kept low.

  As a result, all ships 1, 2, and 3 have a high environmental regulation specification that can pass through the environmental regulation areas R1 and R2 because they pass through the environmental regulation areas R1 and R2 provided in part of the route during operation. Not a ship, but only the ship 1 of the first fleet and the ship 3 of the third fleet are made to be highly environmentally compliant ships and pass through the environmental control areas R1, R2, and the ship 2 of the second fleet is non-environment The ship procurement cost can be kept low in the fleet plan by passing the non-environmental restriction area Rf as a ship with the restriction area specification.

  The reason why the floating body for cargo sea relay, the cargo sea relay system, the cargo sea transportation system, the cargo sea relay method, and the cargo sea transportation method according to the present invention pass through an environmental regulation area provided in a part of the route in operation. Therefore, not all ships are made to be highly environmentally compliant ships that can pass the environmental control area, but only some ships are allowed to pass the environmental control area in response to high environmental regulations, and other ships are non-environmentally controlled. Since it can pass through the non-environmentally restricted area as a region-specific ship and keep the ship procurement cost low in the fleet plan, it is used for freight marine transportation that uses both the environment-regulated area and the non-environmentally restricted area as the route. be able to.
