Description

  The present invention relates to a ballast water supply system that collects and stores ballast water discharged from a ship and supplies the stored ballast water to the ship again.

In order to eliminate the adverse effects of plankton and bacteria in the drained ballast water on the surrounding sea area, ships with ballast tanks less than 5000 m ³ based on the Ballast Water Management Convention adopted by the IMO (International Maritime Organization) in 2004 All ships, including those built after 2009, and existing ships, are required to be equipped with a ballast water purification system from 2017 onwards. At present, apart from the purification treatment system, an offshore exchange system for exchanging ballast water during the navigation of the ship is also used, but this offshore exchange system is prohibited from being used by the above-mentioned Ballast Water Management Convention. Development of a purification system to be mounted is underway, but a suitable purification system has not been developed yet. This has advantages and disadvantages for each of the multiple treatment methods proposed as a purification treatment method, as well as other physical problems (existence or size of excess space installed in the ship) and economic problems (for the entire ship). Considering the problem of the cost ratio), this is due to the fact that a practical purification system that can be mounted on a ship cannot be constructed.

  Patent Document 1 stores ballast water purification means and ballast water that has been subjected to purification treatment from the viewpoint that it is difficult to mount a ballast water purification treatment system that satisfies the requirements of the IMO management treaty on a ship. Proposed is a ballast water supply system (purified water supply system) comprising purified water storage means for supplying ballast water to the ship from the purified water storage means. Although it is unclear how the ballast water supply system disclosed in Patent Document 1 is installed, it is used “in a water area where ballast water is drained to a ship after unloading”, in particular, movable. Because there is no description such as, it is assumed that it will be installed on the offshore platform.

  In addition to the above-mentioned ballast water supply system, Patent Document 1 discloses ballast water storage means for isolating and storing ballast water discharged from a ship from the surrounding sea area, purification means for purifying the ballast water, and ballast after finishing the purification process. We have proposed a ballast water supply system consisting of discharge means for draining water. Further, Patent Document 1 discloses ballast water storage means for storing drained ballast water separately from surrounding sea areas, purification means for purifying ballast water in the ballast water storage means, and ballast water that has been subjected to purification treatment. A ballast water supply system comprising soft water supply means for supplying purified soft water is proposed. The ballast water supply system supplies purified soft water as horticultural, agricultural soft water or drinking water.

JP 2004-025040 A ([Claim 1], [Claim 2], [Claim 5], [0022], [0030], [0032], [0034], [FIG. 1] to [FIG. 4] ])

  The ballast water supply system disclosed in Patent Document 1 is constructed on an offshore platform or the like, and unlike a ship, a large treatment facility is installed in a space with little restrictions, and the purification treatment capacity per unit time of ballast water. As a result, it is not necessary to install a ballast water supply system on the ship, and there is an advantage that the manufacturing cost of the ship is greatly reduced compared to the case where the ballast water supply system is installed on the ship. . Above all, the fact that there is almost no spatial restriction in the installation of the treatment equipment means that the ballast water supply system disclosed in Patent Document 1 is a facility that can be constructed practically.

  However, the ballast water supply system disclosed in Patent Document 1 merely transfers the ballast water supply system mounted on the ship to the outside of the ship, purifies the ballast water pumped in the sea area from which the ship departed, The use form of ballast water that drains in the sea area at the destination of the ship is not different from the conventional one. Utilizing the point that there is almost no spatial restriction on the installation of treatment equipment, purify the ballast water immediately before supplying water to the ship, store the pre-purified ballast water, or drain it from the ship There is only some degree of freedom in the purification process of the ballast water or the timing of the purification process of the ballast water. Patent Document 1 proposes data acquisition related to ballast water to be purified, but since the data acquisition is not related to the ballast water purification process itself, the usage form of ballast water is the same as before. Absent.

  Since the purified ballast water does not contain plankton or bacteria that contaminate the sea area at the destination of the ship, it may be discharged into any sea area. However, due to the conventional usage of ballast water, the purified ballast water is drained in the sea area where the ship arrives, and the ship again injects the ballast water into the ballast tank and the sea area at the other destination. Become. In other words, ballast water that has been purified using time and expense using a ballast water supply system that meets the requirements of the IMO's management treaty is used only on one side of each ship, and transports and drops the cargo. However, it was necessary to repeat the injection of ballast water that had been subjected to purification treatment to the ballast tank again at the same destination and at the same time and expense.

  Such a conventional ballast water usage mode can be considered that the ship is selectively transporting the cargo and the ballast water because the ballast water is mounted instead of the cargo unloaded by the ship. And, since the ballast water may be drained into any sea area as long as it undergoes purification treatment, if the common ballast water is used for all ships, the ship instead of the cargo unloaded by the ship Common ballast water can be installed. This common use of ballast water recycles the ballast water. However, the conventional ballast water purification treatment system does not assume such reuse of ballast water, and no specific means has yet been presented. Then, in order to recycle ballast water, it examined in order to construct the new utilization system of ballast water.

As a result of the examination, it is a ballast water supply system composed of a ship-side equipment mounted on a ship and a facility-side equipment installed on an offshore facility or a ground facility, and the ship-side equipment is provided in the offshore portion of the ship. The ship-side water supply / drain port, the ballast tank provided in the ship, the ship-side water supply / drainage line connecting the ship-side water supply / drainage port and the ballast tank, and the ballast tank to the ship-side water supply / drainage port through the ship-side water supply / drainage line. It consists of a ship-side water supply pump that pumps out ballast water, and the facility-side equipment is connected to and separated from the ship-side water supply and discharge outlets, and is installed on the offshore facility or ground facility, and on the offshore facility or ground facility. A facility-side water intake provided in the underwater part, a storage tank provided in an offshore facility or a ground facility, and a facility connecting the facility-side water supply / drain port and the storage tank A facility-side water supply pump that sends ballast water from the storage tank to the facility-side water supply / drainage port through the facility-side water supply / drainage line, a facility-side intake line that connects the facility-side intake port and the storage tank, and the facility-side intake line A facility-side water intake pump that takes ballast water from the facility-side intake into the storage tank, and a purification treatment device provided in the facility-side water intake line, from the facility-side water supply / drainage line to the facility-side water supply line and the facility-side drainage line The facility-side water supply line is connected to the storage tank water supply line that branches and connects to the storage tank, and the facility-side drainage line connects to the storage tank drainage line that connects to the storage tank. The connection relationship of the side drainage line is switched by the facility side switching valve, and the vessel Or to drain the ballast water to the storage tank, the ballast water was to develop a ballast water supply system that can or water supply to the ship from the storage tank.

  The ship in which the ship side equipment is installed is not limited to any type as long as it is a ship having a ballast tank. “Vessel side water supply and drainage port provided in the sea part of the ship” means the ship side water supply and drainage port provided on the shore side, deck or structure on the deck that appears on the sea with all ballast tanks fully loaded with ballast water. . The “offshore facility” where the facility-side equipment is installed means an offshore structure (offshore platform), a dedicated ship capable of navigating by itself, a barge (truck) that is pulled or pushed by a tow ship, and the like. The “ground facility” where the facility-side equipment is installed means a harbor facility where the ship is berthed. A part of the facility-side equipment may be installed on the offshore facility and the remaining part on the ground facility. In this case, if the offshore facility is an offshore structure, a part of the offshore facility and the remaining part of the ground facility are connected by a fixed-length bridge line, and if the offshore facility is a dedicated ship or barge, The other part of the ground facility is connected with a stretchable bridge line. There may be a plurality of facility-side water supply / drainage ports, and the plurality of facility-side water supply / drainage ports may be connected to one facility-side water supply / drainage line, or a separate facility-side water supply / drainage line is connected to each facility-side water supply / drainage port. May be.

  The ballast water supply system of the present invention collects ballast water mounted on a ship, stores ballast water in a storage tank, supplies the ballast water in the storage tank to the ship again, and recycles the ballast water. For this reason, the ship which constitutes the ballast water supply system of the present invention does not require the purification treatment apparatus which has been conventionally provided, and is provided with a ship side water supply / drain port in the sea part, and the ballast tank provided in the ship and the above-mentioned The ship side water supply line which connects a ship side water supply / drain port is constructed | assembled, and the ship side facility which provided the ship side water supply pump which sends a ballast water from a ballast tank to a ship side water supply / drain port through the said ship side water supply / drainage line is comprised. In addition, the offshore facility or the ground facility constituting the ballast water supply system of the present invention may be used when the ballast water stored in the storage tank is small in an equivalent part in which the ballast tank of the ship-side facility is replaced with the storage tank. In order to make up for the ballast water to be supplied to the facility, a part composed of a facility-side intake line provided with a purification treatment device is added to constitute facility-side equipment.

The ballast water supply system of the present invention is based on the case where ballast water is supplied from a storage tank. However, if you want to supply the ballast water directly from the purification treatment device to the ship, if you need to repurify and drain the ballast water that cannot be collected in the storage tank, if you want to store the ballast water in the storage tank after purifying the ballast water, When the ballast water must be drained from the storage tank, the basic ballast water supply system cannot cope with each case. Therefore, the facility-side equipment of the present invention adds a bypass line that connects the facility-side drainage line branched from the facility-side water supply / drainage line, the facility-side water supply / drainage line, and the facility-side water intake line. the connections of lines and bypass line Ru switched by the facility switching valve. In this case, the facility-side water pump and the facility-side water intake pump may be combined. The facility-side water supply / drainage line, the facility-side water intake line and the bypass line can be connected and the facility-side switching valve can be installed at any number and number of places. The facility-side water supply / drainage line and the facility-side water intake line connected by switching the facility-side switching valve. The flow path and direction of the ballast water flowing to the bypass line may be selectively switched.

When the facility-side equipment to which the bypass line is added is to supply the ballast water directly from the purification treatment device to the ship, the ballast water is sent from the facility-side intake through the facility-side intake line or bypass line to the purification treatment device, and the purification treatment is performed. The purified ballast water is sent from the apparatus to the facility-side water supply / drainage port through the bypass line and the facility-side water supply / drainage line. In addition, when ballast water that cannot be collected in the storage tank has to be purified and drained again, ballast water is sent from the facility-side water supply / drainage port to the purification processing device through the facility-side water supply / drainage line and bypass line, The purified ballast water is drained from the facility-side intake through the bypass line and facility-side intake line. When the ballast water is purified and stored in the storage tank, the ballast water is sent from the facility-side water supply / drainage port to the purification treatment device through the facility-side water supply / drainage line and the bypass line, and from the purification treatment device through the bypass line and the facility-side intake line. The purified ballast water is sent to the storage tank and stored. When the ballast water must be drained from the storage tank, the ballast water is sent from the storage tank to the purification treatment device through the facility-side water supply / drainage line and the bypass line, and from the purification treatment device to the facility through the bypass line and the facility-side intake line. The purified ballast water is drained from the side intake. In addition, the facility-side equipment to which the bypass line is added has an advantage that the facility-side water pump and the facility-side water intake pump can be used together to reduce the installation area or the installation volume of the facility-side equipment with respect to the offshore facility or the ground facility.

According to the ballast water supply system of the present invention, there is basically no need for the ship to pump up the ballast water from the sea, but depending on the port of call, it may be assumed that the ship itself must inject the ballast water into the ballast tank. . From this, the ship-side equipment according to the present invention includes a ship-side intake provided in an underwater portion of the ship, a ship-side intake line connecting the ship-side intake and the ballast tank, and the ship-side intake through the ship-side intake line. A ship side water intake pump that takes in ballast water from the mouth into the ballast tank may be added. Although the ballast water poured into the ballast tank is not purified, the ballast water is purified and stored in the storage tank by the facility side equipment to which the above bypass line is added at the transit destination or the port of call. Drained.

In addition, the ship-side equipment to which the ship-side intake line is added is similar to the facility-side equipment described above, connecting the ship-side water supply / drainage line and the ship-side intake line, and also serving as the ship-side water supply pump and the ship-side intake water pump. Further, a ballast tank water supply line connecting the ballast tank and the ship side water supply / drainage line and a ballast tank drainage line connecting the ballast tank and the ship side water supply / discharge line are added, and the ship side water supply / drainage line, the ship side water intake line , the ballast tank The connection relationship between the water supply line and the ballast tank drain line may be switched by a ship side switching valve. Unlike the facility-side equipment, the ship-side equipment that connects the ship-side water supply / drainage line and the ship-side intake water line through the ballast tank water supply line and the ballast tank drainage line passes the ballast water to the purification treatment device by switching the ship-side switching valve. Rather, the combined use of the ship-side water pump and the ship-side intake pump has the advantage that the installation area or installation volume of the ship-side equipment for the ship can be reduced.

The ballast water supply system of the present invention provides an environment in which the purified ballast water can be used while removing the purification treatment apparatus from the ship. And since the said ballast water can be reused, it has the effect that the time, labor, and cost which purification processing of ballast water requires can be reduced. Since the ship side equipment has a simple configuration in which the ship side water supply / drain port and the ballast tank are connected by the ship side water supply / drainage line provided with the ship side water supply pump, the installation area or the installation volume in the ship can be reduced. And since the ship-side equipment can be made sufficiently small even if a ship-side water intake line, a ballast tank water supply line, and a ballast tank drainage line are added to the ship-side water supply / drainage line, the ship using the present invention is capable of ballast water. This has the effect of reducing capital investment related to use. In addition, since facilities on the facility side are either offshore facilities or ground facilities, there are no particular restrictions on the purification equipment, and a large amount of purified ballast water that meets the requirements of the IMO management treaty can be produced. The ballast water corresponding to the volume of the storage tank can be supplied to the ship in a short time, and the time for pouring the ballast water into the ballast tank can be shortened. And by adding a bypass line and a facility-side switching valve to the facility-side intake line of the facility-side equipment, the ballast water is directly supplied from the purification treatment device, or the ballast water that has not been subjected to purification treatment is supplied by the purification treatment device. The use mode can be diversified, for example, it can be purified and stored in a storage tank or drained as it is. Thereby, the effect which can supply or drain ballast water flexibly according to the size and number of ships using the present invention is acquired.
