Description

TECHNICAL FIELD [0001] The present invention relates to a ballast apparatus using a sponge fuel tank and a vessel having the same,

[0001] The present invention relates to a ballast apparatus using a sponge fuel tank, and more particularly, to a sponge-type auxiliary fuel tank to be connected to a main fuel tank, thereby preventing environmental pollution and reducing installation costs The present invention relates to a ballast apparatus using a sponge fuel tank capable of performing spontaneous combustion.

Ships are a means of transport that accounts for more than half of the world's shipments of goods. In general, ballast tanks are installed to minimize fluctuations in the ship's overall weight and center of gravity due to cargo loading and unloading.

If the cargo is not sufficient, it is difficult to ensure the efficient operation, balance and stability of the propeller and rudder in seawater.

The water stored in the ballast tank is usually called ballast water. This ballast water is a weight that is loaded to adjust the draft and trim of the ship to improve balance and stability of the ship. .

It also performs an auxiliary function that allows the propeller and rudder to operate effectively in seawater when the cargo is not fully loaded.

Such ballast water has been in use since the late 1870s when the ship began to dry with iron. In some cases, the ballast water is not loaded according to the vessel, and ore or sand is used as ballast, but the use of sea water or fresh water as ballast It is universal.

1 and 2 are sectional views of a ship 10 having a ballast tank 11 according to the related art as seen from a front side and a side view when a cargo 14 is unloaded and FIGS. Is a front view and a side view of a vessel (10) having a vessel (11) when loading a cargo (14).

Hereinafter, a ship 10 having a conventional ballast tank 11 will be described with reference to the following.

As shown in FIGS. 1 and 2, when the cargo 14 of the cargo hold 13 is unloaded, the ballast tank 11 is filled with the ballast water 12. At this time, the weight of the ship 10 is satisfied by the ballast water 12, so that the waterline is secured even when the ballast water 12 is leaned.

3 and 4, when the cargo 14 is shipped to the cargo hold 13, the ballast water 12 filled in the ballast tank 11 flows out to the outside. At this time, the weight of the ship 10 is satisfied by the cargo 14, and thus the water line suitable for the operation of the ship 10 is secured.

When the cargo 14 is loaded in the vessel 10, the center of gravity of the vessel 10 is located below the sea level without filling the ballast water tank 12 with the ballast water 12, so that even when an external force such as a wave acts, And ballast water 12 is introduced into the ballast tank 11 so that a certain portion of the ship 10 can be positioned below the sea level as the cargo 14 is shipped, So as to be operated.

However, since the ship 10 having the ballast tank 11 according to the related art uses general seawater or fresh water as the ballast water 12, it is used as a medium for propagating the organisms or pathogens in a specific area to other areas .

The inflow and outflow of the ballast water 12 are carried out in different areas and when the ballast water 12 flows into the other sea area along with the outflow of the ballast water 12, Because.

In order to solve these problems, the International Maritime Organization (IMO) imposes mandatory introduction of facilities to treat marine organisms or pathogens contained in ballast water when ballast water flows in and out. Therefore, researches on ships equipped with purification facilities are being carried out. However, these ships are too expensive to install purification facilities, and even if they have purification facilities, there is a problem that the pathogens can not be completely purified.

In order to solve such a problem, Korean Unexamined Patent Publication No. 10-2010-0058814 (hereinafter referred to as Prior Art 1) has been proposed as a prior art.

In the prior art 1, wings are provided on both sides of the hull to replace the ballast tanks. The effect of floating the ship using the lift acting on the wing during the operation of the ship is described and the effect of maintaining the center of the ship is described. However, since the size of the generated lift is limited, it is difficult to completely replace the ballast tank, There is a problem that it is difficult to apply to large ships.

Another prior art proposed to solve the above problems of the ballast tank is Korean Patent No. 10-0834289 (hereinafter referred to as Conventional Technology 2).

In the case of the prior art 2, the technical content is to provide buoyancy by adjusting the depth of the entire hull by providing a second hull which is slidable in the vertical direction from the first hull. In the case of the ship according to the conventional art 2, the buoyancy of the hull can be increased or decreased by increasing or decreasing the volume of the water immersed in the water.

In the case of a ship according to the prior art 2, it is possible to increase the buoyancy required when loading a cargo, but it is difficult to expect to maintain the draft for stability of the ship in the case of a ballast. Even if the depth of the hull can be adjusted, the weight of the vessel at the time of the ballast is constant, so that the depth at which the vessel is immersed in water is constant. Therefore, there is still a problem with the stability of the ship because the proper draft can not be maintained during the leaning.
