Description

  The present invention relates to a ballast-treated water receiving device and a ship, and more specifically, clean ballast water (ballast treatment) in which aquatic organisms and bacteria are previously killed in a ballast tank of an existing ship that does not have a ballast water treatment device. The present invention relates to a ballast-treated water receiving device for receiving water) and a ship provided with the same.

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

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

  For this reason, it is required that ships can drain clean ballast water that satisfies the Convention.

For example, Patent Documents 1 to 3 disclose specific means for killing aquatic organisms and bacteria.
JP 2004-160437 A JP 2003-200156 A US Pat. No. 6,125,778

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

  However, it is not only costly to install a new processing device, but also in the case of an existing ship, the existing piping and devices take up space, so a new processing device is installed inside the ship. It is difficult to secure space.

  For this reason, the present inventor provides a ballast-treated water supply ship equipped with a treatment device capable of generating clean ballast water (ballast-treated water) that has been killed until the aquatic organisms and bacteria fall below a predetermined value. We are preparing and considering the supply of ballasted water from this ballasted water supply ship to ships that do not have ballast water treatment equipment, especially existing ships. There is a new problem to be solved.

  Generally, since ballast water is taken from a sea chest provided near the bottom of the ship below the surface of the water, a method of receiving ballast water from this sea chest is also conceivable. However, it is extremely difficult to connect a hose for receiving ballast water to a sea chest located below the water surface.

  Even if ballasted water can be received, the ballasted water supply ship does not always have sufficient supply capacity, so it is the same as when taking ballast water from the sea chest as usual. It is not always possible to complete the reception of ballast water in working hours. If the receipt of the ballast water is delayed, there is a risk of hindering the ship's operation schedule, such as delaying the departure.

  As a result of studying the minimum additional equipment in a ship for enabling the reception of ballast treated water that can solve such problems, the present inventor has arrived at the present invention. Ballast that can be easily incorporated into an existing ballast line and can easily receive clean ballast water (ballast treated water) that has been killed in advance until the aquatic organisms and bacteria fall below the specified value. It is an object to provide an apparatus for receiving treated water.

  Another object of the present invention is to provide a ship that can easily receive clean ballast water (ballast treated water), which has been killed in advance until the aquatic organisms and bacteria fall below a predetermined value, in a ballast tank. To do.

It is possible to provide an apparatus for receiving ballast-treated water that can be received.

  In addition, according to the present invention, it is possible to provide a ship that can easily receive clean ballast water (ballast treated water) that has been killed in advance until the aquatic organisms and bacteria fall below a predetermined value in a ballast tank. it can.

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

  FIG. 1 is a side view showing a schematic configuration of a ship equipped with a ballast-treated water receiving device, FIG. 2 is a plan view thereof, and FIG. 3 is a schematic diagram showing an internal configuration of the ship equipped with a ballast-treated water receiving device. .

  In the figure, 1 is a ship for receiving ballast-treated water (built-in ship), and 2 is a device for receiving ballast-treated water. In FIG. 1 and FIG. 2, only the portion of the receiving device 2 provided on the deck 1 </ b> A is shown.

  A ballast line 12 for taking ballast water from a sea chest 11 provided in the vicinity of the ship bottom and pouring water into a ballast tank (not shown) is disposed inside the ship 1. The ballast line 12 is provided with an on-off valve 13 for opening and closing the ballast line 12 and a ballast pump 14 for transferring the ballast water in the ballast line 12 to the ballast tank, both of which are in the ship 1. The existing equipment.

Here, it is assumed that the ballast pump 14 has a capacity of 3000 m ³ / hr.

  The ballast-treated water receiving device 2 according to the present invention includes an introduction pipe 21 for transferring the received ballast-treated water to an existing ballast line 12.

  The introductory piping 21 is connected to the inboard piping portion 21b whose one end 21a is connected to the ballast line 12 in the inside of the ship 1 and the inboard piping portion 21b, and branches in a direction crossing the ship 1 through the deck 1A. A T-shaped portion 21c and a starboard straight pipe portion 21d and a port straight pipe portion 21e formed by extending the ends of the T-shaped portion 21c to the bow side, respectively.

  The place where the one end 21 a of the inboard piping part 21 b is provided is on the inlet side (suction side) of the ballast pump 14 and is positioned between the on-off valve 13 and the ballast pump 14. Accordingly, if the ballast pump 14 is operated with the on-off valve 13 closed, water intake from the sea chest 11 is blocked and water intake from the introduction pipe 21 side becomes possible.

  One end of connection hoses 23a-23d is connected to starboard straight pipe portion 21d and port straight pipe portion 21e via connection pipes 22a-22d, respectively. At the other ends (tips) of the connection hoses 23a to 23d, water receiving ports 23a 'to 23d' for ballast treated water are formed.

  Each of the connecting pipes 22a to 22d branches from the starboard straight pipe portion 21d and the port straight pipe portion 21e to the side, and adjusts the flow rate of the ballast treated water received through the connecting hoses 23a to 23d. In addition, an on-off valve 24 that opens and closes and a flow meter 25 that measures the flow rate thereof are provided.

  Here, two connecting hoses 23a to 23d are provided on the starboard and the port side, respectively. However, the arrangement of the connecting hoses 23a to 23d is not particularly limited, and for example, all four on the starboard side or the port side are provided. It may be arranged.

  Each of the connection hoses 23a to 23d is a flexible hose having a length that can be extended toward a ballast-treated water supply ship, which will be described later, and is hung on a hose handling david 26 standing on the deck 1A of the ship 1. It is supported. The connecting hoses 23a to 23d are individually fed out and stored in the side of the hull by the hose handling davit 26.

  In addition, the connection hoses 23a to 23d are divided into two types of groups in which the diameters of the connection portions of the water receiving ports 23a 'to 23d' are different.

That is, of the four connection hoses 23a to 23d, the three connection hoses 23a to 23c are groups of hoses each having a connection portion with a diameter of 1000 m ³ / hr for the water receiving ports 23a ′ to 23c ′. ing. Therefore, these three connection hoses 23a-23c can be used when receiving ballast treated water from the ballast treated water supply ship provided with the connection part of the diameter for 1000 m < ³ > / hr.

At this time, by using these three connection hose 23a~23c simultaneously from three ships treated ballast water supply vessels each having a supply capacity of 1000 m ³ / hr, receiving the treated ballast water in total 3000 m ³ / hr can do.

In addition, the remaining one connection hose 23d is a group of hoses having a connection portion with a diameter of 3000 m ³ / hr larger than the connection portion of the connection hoses 23a to 23c at the water receiving port 23d ′. .

For this reason, this one connection hose 23d can cope with the reception of ballast-treated water of 3000 m ³ / hr.

When the capacity of the ship's ballast pump is 3000 m ³ / hr, the pump capacity of the ballast treated water supply ship is preferably 3000 m ³ / hr, but the ballast treated water has a small pump capacity depending on the port of call and the ballast treated water supply schedule. Since only a supply ship can be prepared, a large number of locations for receiving ballast water are provided in this way.

  The ship operating company uses the ship operation management website to contact the ballast treated water supply schedule in advance, and the company that owns the ballast treated water supply ship also participates in the above website, It is preferable to flow the possession information of the treated water supply ship and obtain the port entry schedule of the ship.

  Furthermore, it is preferable that the company that owns the ballast treated water supply ship constructs a reception system for supplying the ballast treated water and manages the schedule for supplying the ballast treated water.

  FIG. 4 is a configuration diagram illustrating a configuration of a control unit that controls the receiving device 2.

  The controller 3 is controllably connected to each on-off valve 24 in order to open and close each on-off valve 24 and adjust the opening. Further, each flow meter 25 is connected so that each measured value is input to the control unit 3.

  The input unit 4 receives an input operation for controlling each on-off valve 24 by an operator, for example, and outputs an input signal to the control unit 3. In the control unit 3, by controlling each on-off valve 24 on the basis of an input signal from the input unit 4, the connection hoses 23a to 23d are individually controlled to be opened and closed, and the ballast-treated water is received. Hose 23a-23d is selected.

  The display unit 5 displays various information such as information on the hose receiving the connection hose 23a to 23d and information on the measured value of the flow meter 25 at that time.

  The control unit 3, the input unit 4, and the display unit 5 are installed, for example, in a steering chamber of the ship 1.

  Next, how a ballast treated water is received from a ballast treated water supply ship in a ship 1 equipped with such a ballast treated water receiving device 2 will be described with reference to schematic diagrams shown in FIGS.

FIG. 5 shows a state in which ballast treated water is received from three ballast treated water supply ships 100 each having a supply capacity of 1000 m ³ / hr of ballast treated water.

  Here, the ballast-treated water supply ship 100 is dedicated for ballast water treatment provided with a treatment device for generating clean ballast-treated water that has been killed so that aquatic organisms and bacteria are below a predetermined value. It is a ship. The treatment device kills aquatic organisms and bacteria to a degree that satisfies the Convention, for example, physical treatment methods using heat, ultrasonic waves, ultraviolet rays, silver ions, electricity, filtration, shearing force, Examples thereof include a mechanical treatment method using cavitation or the like, a chemical treatment method using ozone, oxygen removal, chlorine, or the like, or a combined treatment method in which two or more of these treatment methods are combined.

When these three ballast-treated water supply vessels 100 are laid on the vessel 1, by operating the hose handling davit 26, connection hoses 23a and 23b having hose connection portions with a diameter of 1000 m ³ / hr stored therein are accommodated. , 23c are fed out and connected to the supply port of each ballast-treated water supply ship 100. At this time, the control unit 3 opens the on-off valves 24 corresponding to the connection hoses 23a, 23b, and 23c, and closes the on-off valve 24 corresponding to the connection hose 23d having a connection portion having a diameter of 3000 m ³ / hr.

  When the supply of the ballast water is started by the operation of the supply pump in the ballast water supply ship 100, the ballast water is started via each connection hose 23a, 23b, 23c by operating the ballast pump 14 in the ship 1. Is introduced into the ballast line 12. At this time, the on-off valve 13 in the ballast line 12 is in a closed state.

Each ballast treated water supply ship 100 is supplied with 1000 m ³ / hr of ballast treated water. The receiving device 2 can receive a total of 3000 m ³ / hr of ballast-treated water by joining them. Therefore, the required amount of ballast water can be received in the same water injection time as when the ballast water is taken from the sea chest 11 by the ballast pump 14 as usual.

  At this time, the control part 3 adjusts the opening degree of the on-off valve 24 as needed by monitoring the measured value of the flowmeter 25 corresponding to each connection hose 23a-23c, and each connection hose 23a-23c. The flow rate from can also be controlled individually.

  After the ballast water is introduced into the ballast line 12 by the receiving device 2 in this way, water is poured into each ballast tank by the existing ballast line 12 as usual.

  When the required amount of ballast water is introduced, after the operation of the ballast pump 14 is stopped, the connection hoses 23a, 23b, 23c are disconnected from the respective ballast water supply vessels 100 and the hose handling davit 26 is operated. The connection hoses 23a, 23b, and 23c are accommodated.

FIG. 6 shows another embodiment in which the ballast treated water is supplied from the ballast treated water supply ship in the vessel 1. Here, one ballast having a ballast treated water supply capacity of 3000 m ³ / hr is shown. A state in which ballast treated water is received from the treated water supply ship 200 is shown.

When the ballast-treated water supply ship 200 is laid on the ship 1, by operating the hose handling davit 26, the connected hose 23d having a connecting portion with a diameter of 3000 m ³ / hr is delivered to supply the ballast-treated water supply. It connects with the supply port of the ship 200. At this time, the control unit 3 opens the opening / closing valve 24 corresponding to the connection hose 23d, and closes the opening / closing valve 24 corresponding to the connection hoses 23a, 23b, 23c having a connection portion having a diameter of 1000 m ³ / hr.

  When the supply of the ballast water is started by the operation of the supply pump in the ballast water supply ship 200, the ballast water is supplied to the ballast line 12 via the connection hose 23d by operating the ballast pump 14 in the ship 1. Introduce. At this time, the on-off valve 13 in the ballast line 12 is in a closed state.

Since ballast-treated water of 3000 m ³ / hr is supplied from the ballast-treated water supply ship 200, the connection hose 23d having a diameter of 3000 m ³ / hr is used alone, and 3000 m ³ / hr of ballast-treated water is used as it is. Can be introduced. Therefore, the required amount of ballast water can be received in the same water injection time as when the ballast water is taken from the sea chest 11 by the ballast pump 14 as usual.

  At this time, the control unit 3 controls the flow rate from the connection hose 23d by monitoring the measured value of the flow meter 25 corresponding to the connection hose 23d to adjust the opening of the on-off valve 24 as necessary. You can also.

  After the ballast water has been introduced into the ballast line 12 in this way, water is poured into each ballast tank through the existing ballast line 12 as usual.

  When the required amount of ballast water is introduced, after the operation of the ballast pump 14 is stopped, the connection hose 23d is disconnected from the ballast water supply ship 200, and the hose handling davit 26 is operated to store the connection hose 23d. To do.

  Thus, according to the ship 1 equipped with the ballast treated water receiving device 2, clean ballast treated water in the ballast tank can be obtained using the existing ballast line 12 without using the ballast water treating device. Can be stored.

  In addition, the receiving device 2 can selectively use one or more of the plurality of connection hoses 23a to 23d corresponding to the supply capacity of the ballast-treated water supply ship. Even when ballasted water is received from a ballasted water supply ship having a capacity smaller than that of the ballast pump 14, the ballasted water is simultaneously supplied from a plurality of ballasted water supply ships using two or more connecting hoses. , It is possible to receive ballast treated water corresponding to the capability of the ballast pump 14. For this reason, there is no problem that the time required for pouring the ballast water is significantly longer than that at the normal time.

  Moreover, since it is only necessary to add a simple configuration in which the one end 21 a of the introduction pipe 21 is attached to the inlet side of the ballast pump 14 with respect to the existing ballast line 12 in the ship 1, However, large-scale renovation work is not necessary, and it can be installed in a narrow space and can be incorporated extremely easily and inexpensively.

  Further, since a special installation space is not required in the ship 1, there is an advantage that the conventional design drawing can be used almost as it is even in the case of a new shipbuilding.

  In the above description, the receiving device 2 has the four connection hoses 23a to 23d. However, the present invention is not limited to this, and there may be a plurality of connection hoses.

  Further, among the plurality of connection hoses, the number of connection hoses used when receiving the ballast treated water from the ballast treated water supply ship and the diameter of the connection portion of the water receiving port are not limited to the above-described embodiments, and the ballast pump The capacity can be appropriately determined in consideration of the capacity of 14 and the supply capacity of the assumed ballast treated water supply ship.

  Furthermore, the receiving apparatus 2 may install components other than each connection hose and hose handling davit in a ship, and may form the introduction piping 21 with a hose (flexible hose).

  Further, the plurality of water receiving ports for receiving the ballast treated water are not limited to those formed at the distal ends of the connection hoses 23a to 23d described above, and for example, open to the hull side surface 1a of the ship 1 as shown in FIG. It is good also as what to do.

  In this case, for example, the ballast-treated water can be received by connecting the supply hose 300 held by the ballast-treated water supply ships 100, 200 to the water-receiving port 23a '.
