Description

[Technical field]

[0001] The present invention relates to a ship loading / unloading system used for loading / unloading a ship. [Background technology]

[0002] A loading arm is a loading device used to load and unload fluids from a ship or the like. The loading arm is composed of, for example, a base riser, an inboard arm that also serves as a pipe, an outboard arm, and a swivel joint that connects the arms, and can efficiently load and unload crude oil, natural gas, liquefied ammonia, and the like. For example, Patent Document 1 discloses a loading arm used to load and unload fluids such as liquefied natural gas and petroleum between a ship and land or a pier at a port.

[0003] [Patent Document 1] JP 2020-132201 A Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when a coal transport ship is docked, there is an existing loading and unloading facility such as a pier used for loading and unloading coal at the berth. In the existing loading and unloading facility, for example, an unloader arm that moves horizontally on rails laid on the berth rotates to reach the entire deck of the ship to load and unload the coal.

[0005] In recent years, from the perspective of carbon neutrality, there has been a shift away from fossil fuels to fuels such as hydrogen and ammonia, which do not emit CO2 when burned. For example, when a liquefied ammonia transport ship docks at a berth or pier that has the above-mentioned loading and unloading facilities, loading and unloading facilities for the liquefied ammonia must also be installed, but the space available for installing new facilities is limited. In some cases, the construction of additional berths or piers is not acceptable due to the impact on the environment, etc. There is a demand for loading and unloading facilities that can be installed reliably in limited spaces.

[0006] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a highly convenient cargo handling system for a ship that is capable of handling the loading and unloading of multiple objects. [Means for solving the problem]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The ship loading / unloading system of the present invention is configured such that, in addition to the existing loading / unloading devices such as unloaders, a new loading / unloading device is provided for objects different from the existing loading / unloading devices, and a control device controls the positions of the loading / unloading devices, allowing the two loading / unloading devices to coexist and load / unload a plurality of objects.

[0011] 1 is a block diagram showing an example of the configuration of a ship loading / unloading system 1 according to an embodiment of the present invention. The ship loading / unloading system 1 has a first loading / unloading apparatus 10, a second loading / unloading apparatus 20, a first driving source 30, a second driving source 40, and at least one control device 50 that controls the first loading / unloading apparatus 10 and the second loading / unloading apparatus 20.

[0012] 2 to 4 are diagrams that show an example of the configuration of the first loading / unloading apparatus 10. In FIG. The first loading / unloading device 10 is attached to and fixed to a stand 11. The stand 11 has a base at a predetermined height, and the first loading / unloading device 10 is placed on this base. The height of the base of the stand 11 can be set as appropriate. A first running part 12 such as wheels is provided on the lower part of the stand 11. The stand 11 is placed on a berth, and can move on the berth by the first running part 12. The first loading / unloading device 10 can move on the berth together with the stand 11.

[0013] The first loading device 10 is capable of loading and unloading a first object at a first loading position A1 (see FIG. 5 or FIG. 11). The first object may be an object different from a second object described below. The first loading device 10 may be a loading device for a fluid, and the first object may be a fluid. The fluid may be, for example, hydrogen or ammonia, and is preferably a non-fossil fuel that does not produce CO2 when burned.

[0014] The first loading device 10 has a loading arm 13 that is detachably connected to the piping of the ship 4, and a jumper arm 14 that is connected to the loading arm 13 and detachably connected to the piping 2 on land. The first loading device 10 can have one or more loading arms 13 and a corresponding jumper arm 14. The loading arm 13 has a predetermined movable range and may be a general one that is connected to the piping on the ship side to perform loading and unloading. The piping 2 on land is a fixed piping that extends to the berth and is connected to a receiving storage tank (not shown). The piping 2 is fixed, for example, to the center of the berth. The first loading position A1 is a position where the jumper arm 14 can be connected to this fixed piping 2. In other words, the jumper arm 14 is, for example, a multi-joint movable piping joint, and can be connected to the fixed piping 2 at the first loading position A1 where the first loading device 10 performs loading and unloading of the first object. In addition, the jumper arm 14 may be installed on the land pipe 2 side and connected to the loading arm 13 installed on the stand 11.

[0015] The second loading / unloading device 20 is provided with a second running part 21 such as wheels, and is movable on a rail 3 laid on the berth. The rail 3 is laid horizontally on the berth so as to be approximately parallel to the ship at anchor (see Fig. 5, Fig. 8, Fig. 11 to Fig. 13). The second loading / unloading device 20 is capable of loading / unloading a second object at the second loading / unloading position A2 (see Fig. 8 or Fig. 12 and Fig. 13). The second loading / unloading device 20 may be a loading / unloading device for bulk materials, and the second object may be bulk materials such as coal. The second loading / unloading device 20 may be an existing facility such as a pier, and is provided with an unloader 23 having an arm 22 that can rotate within a predetermined movable range, for example. The second loading / unloading device 20 may have one or more unloaders 23.

[0016] The first driving source 30 is connected to the first loading and unloading apparatus 10 and supplies power to the first loading and unloading apparatus 10. The second driving source 40 is connected to the second loading and unloading apparatus 30 and supplies power to the second loading and unloading apparatus 20. The first driving source 30 and the second driving source 40 may be, for example, sources that supply electricity via laid cables or sources that supply power via an internal combustion engine or the like.

[0017] As shown in Figures 2 to 4, the platform 11 to which the first loading / unloading apparatus 10 is attached can move on the rails 3 on which the second loading / unloading apparatus 20 runs, by means of the first running section 12. In other words, both the first loading / unloading apparatus 10 and the second loading / unloading apparatus 20 can run on the rails 3 and share the rails 3. Alternatively, the platform 11 may move along a predetermined movement path on the berth separately from the rails 3.

[0018] In the ship loading / unloading system 1, the operation of the entire system is controlled by at least one control device 50. At least one control device 50 controls the movement of the first loading / unloading device 10 and the second loading / unloading device 20, and can control the positions of the first loading / unloading device 10 and the second loading / unloading device 20, for example, in the horizontal direction (a direction substantially parallel to the ship at anchor). For example, a first control device facing the first loading / unloading device 10 and a second control device facing the second loading / unloading device 20 can be provided as the control device 50. The control device 50 may be a general control device including an input unit that receives input, a calculation unit that performs calculation processing based on the input from the input unit, a control unit that controls the calculation unit, a storage unit that stores a control program and various data, an output unit that outputs the results of the calculation processing, and the like. The control device 50 may be in a form that moves together with the first loading / unloading device 10 and / or the second loading / unloading device 20, or may be in a form that is arranged in a control room and connected to the movable first loading / unloading device 10 and / or the second loading / unloading device 20 by a cable or the like, as shown in FIG. 4.

[0019] In this embodiment, the second loading position A2 where the second loading device 20 performs loading has a predetermined range, and the range of the second loading position A2 includes the first loading position A1 where the first loading device 10 performs loading. In particular, since the first loading position A1 of the first loading device 10 is determined by the position of the land fixed pipe 2, the first loading position A1 cannot be easily changed. In addition, the second loading position A2 of the second loading device 20 cannot be easily changed when the second loading device 20 is an existing facility such as a pier. Therefore, the loading devices 10 and 20 are moved as follows so that the first loading device 10 and the second loading device 20 can coexist without changing the first loading position A1 and the second loading position A2.

[0020] An example of control of the ship loading / unloading system 1 according to this embodiment when loading / unloading is performed by the first loading apparatus 10 will be described with reference to Figures 5 to 7. In this example, two second loading apparatus 20 and one first loading apparatus 10 are arranged in this order in a straight line and move on the same rail 3.

[0021] For example, when liquefied ammonia is received as a first object from a liquefied ammonia transport ship 4, the positions of the first loading apparatus 10 and the second loading apparatus 20 are controlled so that the first loading apparatus 10 is at the first loading position A1 and the second loading apparatus 20 is at the second retracted position B2 where it does not physically interfere with the first loading apparatus 10 at the first loading position A1. The second retracted position B2 is, for example, a position where the stationary unloader 23 of the second loading apparatus 20 does not physically interfere with the loading arm 13 of the first loading apparatus 10 at the first loading position A1 at least in the horizontal direction, and, for example, a position where the unloader 23 (including the arm 22) of the second loading apparatus 20 does not physically interfere with the movable range C1 of the loading arm 13 of the first loading apparatus 10 at the first loading position A1. That is, the second retracted position B2 may be a position where the stationary unloader 23 is not physically included in the movable range C1 of the loading arm 13 at the first loading position A1. Although FIG. 5 shows the movable range C1 of the loading arm 13 in a plane, the movable range C1 is a three-dimensional range. That is, the second retracted position B2 of the second loading device 20 can be set to a predetermined range so that the stationary unloader 23 is not physically included in the movable range C1, taking into consideration not only the horizontal direction but also the height direction. As shown in FIG. 5 and FIG. 7, the two second loading devices 20 can be retracted to the second retracted position B2, which is on one side of the first loading position A1 of the first loading device 10 and is on a side different from the first retracted position B1. When the second loading device 20 is in the second retracted position B2, the second loading device 20 is not driven and does not perform loading. The first loading device 10 is connected to the onshore piping 2 by the jumper arm 14 at the first loading position A1. The first loading device 10 loads a first object at a first loading position A1.

[0022] As shown in FIG. 6, the control device 50 moves the second loading device 20 to the second retracted position B2 (step S11). For example, the control device 50 determines whether the second loading device 20 is in the second retracted position B2, and when it is determined that the second loading device 20 is not in the second retracted position B2, it can move the second loading device 20 to the second retracted position B2. With the second loading device 20 disposed in the second retracted position B2, the control device 50 moves the first loading device 10 to the first loading position A1 (step S12). Here, the second retracted position B2 is not on the movement path of the first loading device 10 to the first loading position A1. For example, as shown in FIG. 5 and FIG. 7, the second retracted position B2 is on one end side of the linear rail 3, and the movement path of the first loading device 10 from the first retracted position B1 to the first loading position A1 does not include the second retracted position B2. By moving the second loading apparatus 20 to the second retracted position B2 first, the first loading apparatus 10 can move smoothly to the first loading position A1 without the second loading apparatus 20 blocking its movement path.

[0023] Next, an example of control of the marine vessel cargo handling system 1 according to this embodiment when cargo handling is performed by the second cargo handling equipment 20 will be described with reference to Figs. For example, when coal is received as the second object from a coal transport ship 5, the positions of the first loading apparatus 10 and the second loading apparatus 20 are controlled so that the second loading apparatus 20 is at the second loading position A2 and the first loading apparatus 10 is at the first retracted position B1 where it does not physically interfere with the second loading apparatus 20 at the second loading position A2. The first retracted position B1 may be, for example, a position where the stationary loading arm 13 of the first loading apparatus 10 does not physically interfere with the unloader 23 of the second loading apparatus 20 at the second loading position A2 at least in the horizontal direction, and may be, for example, a position where the loading arm 13 of the first loading apparatus 10 does not physically interfere with the movable range C2 of the unloader 23 (including the arm 22) of the second loading apparatus 20 at the second loading position A2. That is, the first retracted position B1 is a position where the loading arm 13 in a stationary state is not physically included in the movable range C2 of the unloader 23 at the second loading position A2. Although FIG. 8 shows the movable range C2 of the unloader 23 in a plan view, the movable range C2 is a three-dimensional range. That is, the first retracted position B1 of the first loading device 10 can be set to a predetermined range so that the loading arm 13 in a stationary state is not physically included in the movable range C2, taking into consideration not only the horizontal direction but also the height direction. As shown in FIG. 8 and FIG. 10, the first loading device 10 can be retracted to the first retracted position B1, which is on one side of the second loading position A2 of the two second loading devices 20 and is on a side different from the second retracted position B2. When the first loading device 10 is in the first retracted position B1, the first loading device 10 is not driven and does not perform loading. The second loading device 20 performs loading of the second object at the second loading position A2.

[0024] As shown in FIG. 9, the control device 50 moves the first loading apparatus 10 to the first retracted position B1 (step S21). For example, the control device 50 determines whether the first loading apparatus 10 is in the first retracted position B1, and when it is determined that the first loading apparatus 10 is not in the first retracted position B1, it can move the first loading apparatus 10 to the first retracted position B1. With the first loading apparatus 10 placed in the first retracted position B1, the control device 50 moves the second loading apparatus 20 to the second loading position A2 (step S22). Here, the first retracted position B1 is not on the movement path of the second loading apparatus 20 to the second loading position A2. 8 and 10, the first retraction position B1 is at the other end side of the straight rail 3 (the side different from the second retraction position B2), and the movement path of the second loading device 20 from the second retraction position B2 to the second loading position A2 does not include the first retraction position B1. By moving the first loading device 10 to the first retraction position B1 first, the second loading device 20 can move smoothly to the second loading position A2 without the movement path being blocked by the first loading device 10.

[0025] In the above explanation, an example has been given in which two second loading / unloading apparatuses 20 and one first loading / unloading apparatus 10 are arranged in a straight line in this order and move on the same rail 3. However, as another example, the ship loading / unloading system 1 may be arranged in such a way that the first loading / unloading apparatus 10 is arranged between two second loading / unloading apparatuses 20 and moves on the same rail 3. Hereinafter, another example of control of the marine vessel cargo handling system 1 according to this embodiment when cargo handling is performed by the first cargo handling apparatus 10 will be described with reference to FIG.

[0026] For example, when liquefied ammonia is received as a first object from a liquefied ammonia transport ship 4, the positions of the first loading apparatus 10 and the second loading apparatus 20 are controlled so that the first loading apparatus 10 is at the first loading position A1 and the second loading apparatus 20 is at the second retracted position B2 where it does not physically interfere with the first loading apparatus 10 at the first loading position A1. The second retracted position B2 is, for example, a position where the stationary unloader 23 of the second loading apparatus 20 does not physically interfere with the loading arm 13 of the first loading apparatus 10 at the first loading position A1 at least in the horizontal direction, and, for example, a position where the unloader 23 (including the arm 22) of the second loading apparatus 20 does not physically interfere with the movable range C1 of the loading arm 13 of the first loading apparatus 10 at the first loading position A1. That is, the second retracted position B2 may be a position where the unloader 23 in a stationary state is not physically included in the movable range C1 of the loading arm 13 at the first loading position A1. Although FIG. 11 shows the movable range C1 of the loading arm 13 in a plan view, the movable range C1 is a three-dimensional range. That is, the second retracted position B2 of the second loading device 20 can be set to a predetermined range so that the unloader 23 in a stationary state is not physically included in the movable range C1, taking into consideration not only the horizontal direction but also the height direction. As shown in FIG. 11, the two second loading devices 20 (24, 25) located on both sides of the first loading device 10 can be retracted to the second retracted positions B2 (B21, B22) so as to be away from the first loading position A1 of the first loading device 10. When the second loading device 20 is in the second retracted position B2, the second loading device 20 is not driven and does not perform loading. The first loading / unloading device 10 is connected to the onshore piping 2 at the first loading / unloading position A1 by a jumper arm 14. The first loading / unloading device 10 performs loading / unloading of a first object at the first loading / unloading position A1.

[0027] At this time, the control of the first loading / unloading device 10 and the second loading / unloading device 20 by the control device 50 may involve executing steps S11 and S12 described with reference to FIG. 6 in that order, or step S11 may be executed after step S12.

[0028] Next, another example of control of the marine vessel cargo handling system 1 according to this embodiment when cargo handling is performed by the second cargo handling apparatus 20 will be described with reference to Figs. For example, when coal is received as the second object from a coal transport ship 5, the positions of the first loading apparatus 10 and the second loading apparatus 20 are controlled so that the second loading apparatus 20 is at the second loading position A2 and the first loading apparatus 10 is at the first retracted position B3 where it does not physically interfere with the second loading apparatus 20 at the second loading position A2. The first retracted position B3 is, for example, a position where the stationary loading arm 13 of the first loading apparatus 10 does not physically interfere with the unloader 23 of the second loading apparatus 20 at the second loading position A2 at least in the horizontal direction, and is, for example, a position where the loading arm 13 of the first loading apparatus 10 does not physically interfere with the movable range C2 of the unloader 23 (including the arm 22) of the second loading apparatus 20 at the second loading position A2. In other words, the first retracted position B3 may be a position where the loading arm 13 in a stationary state is not physically included in the movable range C2 of the unloader 23 at the second loading position A2. Note that, although the movable range C2 of the unloader 23 is shown in a plane in Fig. 8, the movable range C2 is a three-dimensional range. In other words, the first retracted position B3 of the first loading device 10 can be set to a predetermined range so that the loading arm 13 in a stationary state is not physically included in the movable range C2, taking into consideration not only the horizontal direction but also the height direction. As shown in Figures 12 and 13, when two second loading apparatuses 20 (24, 25) located on either side of the first loading apparatus 10 each have a second loading position A2 (A21, A22), the first loading apparatus 10 can be moved appropriately to be set in a first retracted position B3 where the first loading apparatus 10 does not physically interfere with at least one of the second loading apparatuses 24 (or 25) at the second loading position A21 (or A22). When in the first retracted position B3, the first loading apparatus 10 is not driven and does not perform loading. The second loading apparatus 20 loads the second object at the second loading position A2.

[0029] As shown in Fig. 14, the control device 50 moves the second loading device 20 to the second loading position A2 (step S31). Then, for example, the control device 50 judges whether the first loading device 10 is in the first retracted position B3, and when it is judged that the first loading device 10 is not in the first retracted position B3, the control device 50 retracts the first loading device 10 to the first retracted position B3 (step S32). When two second loading devices 20 (24, 25) located on both sides of the first loading device 10 are used, the first loading device 10 can be appropriately retracted to the first retracted position B3 relative to the second loading device 20 (24 or 25) in accordance with the movement of any one of the second loading devices 20 (24 or 25) to the second loading position A2. For example, as shown in Figures 12 and 13, when one of the second loading apparatuses 20 (24 or 25) is moved to the second loading position A2 (A21 or A22), the first loading apparatus 10 follows it and moves in the same direction as the movement of the second loading apparatus 20 (24 or 25) to retreat to the first retreat position B3. Also, when the other second loading apparatus 20 (25 or 24) is moved to the second loading position A2 (A22 or A21), the first loading apparatus 10 follows it and moves in the same direction as the movement of the second loading apparatus 20 (25 or 24) to retreat to the first retreat position B3. The control device 50 can control the positions of the first loading device 10 and the second loading device 20 in conjunction with the movement of the second loading device 20 to the second loading position A2 so that the first loading device 10 is in the first evacuation position B3 where it does not physically interfere with the second loading device 20 at the second loading position A2.

[0030] As described above, the ship loading / unloading system according to the embodiment of the present invention includes a first loading / unloading device mounted on a platform and configured to be movable together with the platform, a second loading / unloading device configured to be movable on rails, a first drive source that supplies power to the first loading / unloading device, a second drive source that supplies power to the second loading / unloading device, and at least one control device that controls the positions of the first loading / unloading device and the second loading / unloading device. The first loading / unloading device is capable of loading / unloading a first object at a first loading position, and the second loading / unloading device is capable of loading / unloading a second object at a second loading position. When loading / unloading the first object, the control device controls the positions of the first loading / unloading device and the second loading / unloading device so that the first loading / unloading device is at the first loading position and the second loading / unloading device is at a first retracted position that does not physically interfere with the first loading / unloading device at the first loading position. Moreover, when the second object is to be loaded, the control device controls the positions of the first loading device and the second loading device so that the second loading device is at the second loading position and the first loading device is at the second retracted position where it does not physically interfere with the second loading device at the second loading position. According to this embodiment, the first loading device is attached to a movable stand to be movable, and in addition to loading the first object at the first loading position, when the second loading device is to be loaded, the control device moves the first loading device to the second retracted position where it does not physically interfere with the second loading device, thereby enabling loading and unloading of multiple objects. The second loading device can utilize existing equipment, and a highly convenient ship loading and unloading system can be provided in which multiple objects can be loaded and unloaded by controlling the position of the second loading device, which is an existing equipment, and the position of the new first loading and unloading device. Even when the space for installing new equipment is limited, the space of the existing equipment can be utilized to provide a ship loading and unloading system that can operate in a limited space.

[0031] The first object is a fluid, the first loading device is a loading device for fluids equipped with a loading arm, the second object is bulk material such as coal, and the second loading device is a loading device for bulk material equipped with an existing unloader. A highly convenient ship loading system capable of loading and unloading both fluids and bulk material can be provided.

[0032] The first retract position is a position where the loading arm does not physically interfere with the range of movement of the unloader at the second loading position, and the second retract position is a position where the unloader does not physically interfere with the range of movement of the loading arm at the first loading position. By setting the first retract position and the second retract position in this manner, it is possible to ensure that the unloader does not physically interfere with the operation of the loading arm when loading a first object, and that the loading arm does not physically interfere with the operation of the unloader when loading a second object, making it possible to perform either type of loading and unloading, and thus providing a highly convenient ship loading and unloading system.

[0033] The first loading / unloading device can have a jumper arm that is coupled to the loading arm and detachably connected to a piping on land. The first loading / unloading position is a position where the jumper arm can be connected to this piping. By providing the piping and the detachable jumper arm, even if the first loading / unloading device is movable, it can be reliably attached and detached to the fixed piping on the land side, and loading / unloading can be performed reliably. For example, a ship loading / unloading system can be provided that can use existing fixed piping to load and unload the first object, which is a fluid.

[0034] The platform of the first loading device is movable on the rails on which the second loading device is movable. The second loading device and the rails may be existing equipment, and the first loading device can be made movable by utilizing the existing equipment. By utilizing the existing equipment, multiple objects can be loaded and unloaded without requiring new space. In addition, by making both the first loading device and the second loading device movable on the rails, it becomes easier to control the horizontal positions of the first loading device and the second loading device.

[0035] The first object can be a non-fossil fuel such as hydrogen or ammonia that does not generate CO2 when burned, and the second object can be a fossil fuel. In recent years, a shift from fossil fuels to such non-fossil fuels has been advocated, and carbon neutral efforts are thriving. The ship loading and unloading system according to this embodiment can load and unload not only fossil fuels but also non-fossil fuels, and can contribute to such efforts. In addition, for example, by making the second loading and unloading device an unloader for coal installed on a pier or the like, the newly installed loading and unloading device can be only the first loading and unloading device for non-fossil fuels, and a highly convenient ship loading and unloading system can be provided that utilizes existing facilities for fossil fuels.

[0036] Although each embodiment of the present invention has been described above, various modifications and changes are possible without departing from the spirit of the present invention. For example, the first loading / unloading device is not limited to a device that moves linearly between the first loading position and the first retracted position using rails or the like, but may move along a non-linear movement path. In addition, the second loading / unloading device is not limited to an existing device, but the first loading / unloading device and the second loading / unloading device that constitute the ship loading / unloading system may be newly installed. The number of each component that constitutes the ship loading / unloading system is also not limited to those described here, as long as it is in line with the spirit of the present invention.
