1 to 5, a grid-type ballast system for a VLCC according to the present invention includes a grid-type ballast structure 100 and a ballast structure 200.

The grid type ballast structure 100 is installed in the cargo tank 10 with a lattice structure.

The grid type ballast structure 100 has a space 110 formed therein to allow the ballast structure 200 for ballast control to be installed therein.

The space 110 is formed in each of the zones in which the lattice-shaped ballast structure 100 has a lattice structure.

When the crude oil 11 is stored in the cargo tank 10 while the ballast structure 200 is installed in the space 110, the ballast structure 200 is compressed in the space portion 110, . ≪ / RTI >

When the crude oil 11 is discharged from the cargo tank 10 while the ballast structure 200 is installed in the space 110, the ballast structure 200 is filled with the ballast water 12, The ballast structure 200 is expanded and ballasted to the ballast water 12.

The grid-type ballast structure 100 can be installed in the cargo tank 10 to prevent ballasting of the crude cargo carrier (VLCC) as well as column support and sloshing of the cargo tank 10 .

That is, since the grid-type ballast structure 100 is installed in the cargo tank 10, it is not necessary to provide a conventional swash plate bulkhead.

The ballast structure 200 may be installed in the grid-type ballast structure 100 to fill the ballast water 12 to control the ballast.

The ballast structural body 200 is installed in the space portion 110 formed in the grid type ballast structure 100 and contracts and expands according to the inflow and outflow of the ballast water 12 in the space portion 110 .

That is, when the crude oil 11 is stored in the cargo tank 10 while being installed in the space 110, the ballast structure 200 can be contracted to maximize the storage space of the crude oil 11, 10, the ballast structure 200 can be filled with the ballast water 12 and ballasted.

For this purpose, the ballast structure 200 is made of a bellows-type elastic body so that the ballast structure 200 can be contracted and expanded according to the inflow and outflow of the ballast water 12 in the space portion 110.

On the other hand, the ballast structure is preferably made of a hard rubber material so that the ballast water can be easily injected and can withstand water pressure.

The ballast structure 200 is installed in each of the space portions 110 installed in each zone of the grid-type ballast structure 100.

The connecting hose 300 is connected to each of the ballast structure 200 and the ballast structure 200 so that the ballast water 12 can be moved.

A pipe 400 is installed in the ballast structure 200 to inject and discharge the ballast water 12 into the ballast structure 200 when the crude oil 11 is stored and discharged into the cargo tank 10 .

In the pipe 400, a flow rate gauge 500 is installed to check the flow rate of the ballast water 12 injected into the ballast structure 200.

Therefore, when the ballast water 12 is injected into the ballast structure 200, the flow rate gauge 500 accurately grasps the injection amount of the ballast water 12, and safety can be maximized.

On the other hand, the ballast water 12 filled in the ballast structure 200 can utilize both seawater and fresh water.

The present invention is characterized in that a grid type ballast structure 100 for ballasting is installed in the cargo tank 10 and a ballast structure 200 in which the ballast water 12 is injected is installed between the grid type ballast structures 100 So that there is no need to install an existing ballast tank.

In addition, since the grid-type ballast structure 100 is installed in the cargo tank 10, the size of the cargo tank 10 can be increased and the amount of cargo to be loaded can be increased.

According to another aspect of the present invention, a lattice type ballast structure 100 is installed in a cargo tank 10 of a crude oil carrier (VLCC) in which crude oil 11 is filled and transported, When the crude oil 11 is filled in the cargo tank 10, the ballast structure 200 is contracted to occupy no space in the cargo tank 10, And is applied to ships having a grid-type ballast system for VLCC so that the ballast can be controlled by the ballast water 12 by injecting the ballast water 12 into the ballast structure 200 when the crude oil 11 is discharged .

That is, a lattice type ballast structure 100 having a space 110 formed therein is provided in the cargo tank 10, and a ballast structure of an elastic body, which can be contracted and expanded in the space portion 110 of the lattice type ballast structure 100, It is not necessary to provide a separate ballast tank by the grid type ballast structure 100, so that it is possible to prevent the column support and sloshing as well as the increase in the amount of cargo, The ballast structure 200 is contracted to create voids in the space portion 110 in the grid type ballast structure 100 to fill the cargo tank 10 with the crude oil 11 to adjust the ballast with the crude oil 11, 10 can be applied to all ships capable of controlling the ballast by filling the ballast structure 200 with the ballast water 12.

The operation of the grid-type ballast system according to the present invention will be described below.

When the crude oil 11 is filled in the cargo tank 10 and the crude oil carrier VLCC is operated, the ballast can be adjusted by the crude oil 11 filled in the cargo tank 10.

At this time, when the cargo tank 10 is filled with crude oil 11, the ballast structure 200 provided in the space portion 110 of the grid-type ballast system 100 is contracted to create a void space in the space portion 110, The inside of the tank 10 becomes empty.

As the ballast structure 200 is contracted and shrunk to generate space in the grid-type ballast system 100, the crude oil 11 can be filled in the cargo tank 10.

After the crude oil 11 is loaded into the cargo tank 10 and the crude oil 11 is discharged after the operation, the ballast water 12 is injected into the ballast structure 200 through the pipe 400, The ballast 12 can be controlled by the ballast.

That is, when the crude oil 11 is discharged from the cargo tank 10, the ballast structure 200 injects the ballast water 12 through the pipe 400 and connects the ballast structure 200 to the connection hose 300 The ballast water 12 is injected into the whole of the ballast structural body 200 through the ballast water supply pipe 20.

As the ballast structure 200 is expanded and the ballast water 12 is injected, the ballast water can be controlled by the ballast water 12.

In addition, since the ballast structure 200 is made of an elastic body, the ballast water 12 for ballast control can be easily injected.

When the ballast structural body 200 is filled with the ballast water 12 through the pipe 400, the injection amount of the ballast water 12 can be grasped and accurately injected by the flow rate gauge 500, .

Therefore, in the lattice type ballast system according to the present invention, the lattice type ballast structure 100 is installed so that the space portion 110 is formed in the cargo tank 10, It is possible to replace the swash plate with the swash plate bulkhead 100 so that the column support and sloshing in the cargo tank 10 can be prevented.

Since the ballast structure 200 made of an elastic material is provided in the space portion 110 of the grid type ballast structure 100 so that it can be shrunk and expanded, when the crude oil 11 is filled in the cargo tank 10, It is possible to fit the ballast by putting the ballast water 12 into the ballast structure 200 in a state where all the crude oil 11 is removed, thereby eliminating the painting and maintenance cost for preventing corrosion of the sea water.

In addition, since the grid type ballast structure 100 and the ballast structure 200 are installed in the cargo tank 10 and the ballast can be adjusted by the ballast water 12, it is not necessary to provide a separate ballast tank, It is possible to increase the size of the vehicle 10 and increase the cargo loading capacity.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and any person skilled in the art can make various modifications without departing from the gist of the present invention. It is to be understood that such changes and modifications are intended to fall within the scope of the appended claims.
