Description

BALLAST-FREE SHIP CAPABLE OF ADJUSTING THE DRAFT [0002]

The present invention relates to a ballast-free ship capable of adjusting the draft, and it is possible to adjust the buoyancy and draft according to the amount of cargo to be loaded without forming a ballast tank provided inside the hull, thereby securing the ballast tank and the ballast water treatment apparatus Ballast ship capable of controlling the draft without concern for marine pollution due to the discharge of ballast water.

In the case of ordinary ships including container ships carrying various cargoes, ballast tanks are generally provided inside the hull to maintain proper draft at the time of operation.

This is because of the problems that can occur when flying an oversized ship, which is as dangerous as an oversized operation of a ship. In the case of a ballast operation, the hull can not be sufficiently immersed from the surface of the water. Due to the unbalance of the hull due to the hull can be tilted.

In addition, the propeller of the propulsion device floats on the surface of the water, and the propulsion efficiency is seriously deteriorated or seriously damaged, which may cause a serious problem on the safety. Therefore, there is a problem that the stable operation of the ship is difficult.

Therefore, when the amount of the load is small or the ball is small in the navigation of the ship, a means is required to deepen the draft to avoid the above-mentioned problems.

Conventionally, the load is divided into upper and lower portions of the hull so as to maintain stability. However, it is difficult to secure the stability of the hull by itself.

In this case, a heavy load is intentionally loaded inside the hull, lowering the center of gravity of the hull downward, and keeping the draft of the hull in a state where stable operation is possible. Such a heavy load is called a ballast.

1, when the satisfactory draft is not maintained by only the cargo C loaded on the ship 10, the ballast tank T provided in the ship 10 is filled with seawater or fresh water, , And if it is not enough, sand, gravel, earth, etc. may be loaded to secure the weight.

On the other hand, in the case of the ballast described above, since ballast water for filling seawater or fresh water into the ballast tank is commonly used, there is a possibility that the discharge of the ballast water may propagate the organisms or pathogens in a specific region to other regions There is a problem.

In other words, when the inflow and outflow of ballast water occur in different areas, the inflow of foreign species or pathogens that have flowed in together with the inflow of ballast water may be released together with the discharge of ballast water to other areas.

In particular, in order to minimize the damage caused by foreign species and to prevent marine pollution mainly in the United States, which experienced such damage, some countries have started to develop technology for ballast water treatment system from the 1980s, and IMO Currently, most countries in the maritime, shipbuilding and marine industries have developed or are conducting the technology development worldwide in response to the International Maritime Organization's Ballast Water Regulation Convention.

However, since such a ballast water treatment apparatus requires a high cost for securing facilities, there is a problem that it is difficult to widely apply it to small ships and various ships.

The problem to be solved by the present invention is that it is possible to control the buoyancy and draft according to the amount of cargo to be loaded without constructing a ballast tank provided inside the hull and there is no need to secure a ballast tank and a ballast water treatment device, And to provide a ballast-free vessel capable of adjusting the draft without any concern of marine pollution due to discharge.

Here, the main thrusters 16 are disposed behind the hull 10 to provide a propulsion force to the hull 10, and the main thrusters 16 are disposed on the front side of the hull 10 through the metering section (400 in Figs. 3 to 4) And can be raised and lowered in the vertical direction according to the draft of the hull 10.

More specifically, as shown in FIG. 9A, when the draft is kept deep by the cargo C loaded on the hull 10, the main thruster 16 can be kept in a state of being sufficiently water-locked .

On the other hand, as shown in FIG. 9 (b), when the draft is insufficient and the draft is insufficient, the main thruster 16 can be lowered and maintained in a state of being fully submerged in the water surface.

Accordingly, the main thruster 16 according to the present embodiment is always kept sufficiently locked on the water surface, thereby maximizing the propulsion efficiency. When the main thruster 16 floats above the water surface, It can be prevented from being damaged by severe damage.

At this time, the ascending and descending of the main thruster 16 can be similarly controlled through the above-described control unit (500 in FIG. 4).

In addition, in the present embodiment, as shown in FIG. 10, not only the main thrusters 16 alone can supply the thrust force which is insufficient through the sub-rusters 340 provided in the respective floating units 300, 10) can be enabled.

That is, when a sudden hull of a hull is required in a variety of situations including an emergency occurring during the operation of the ship, the sub-rusters 340 provided in the floating unit 300 rotate in opposite directions, Can be obtained.

In addition, if a hurricane is required when a narrow line such as a river or a canal is needed, the hull 10 can be turned through the above-described subursters 340 even if there is not enough room for a hurricane.

Although specific embodiments of the present invention have been illustrated and described, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and alternative arrangements included within the spirit and scope of the invention. It is self-evident to those of ordinary skill.

Therefore, such modifications or variations should not be individually understood from the technical spirit and viewpoint of the present invention, and modified embodiments should be included in the claims of the present invention.

In addition, embodiments of the present invention can be practiced independently of each other, and can be implemented in various combinations. Through the embodiments of the present invention in which the object of the present invention can be specifically realized, It is possible to provide a ballast-free ship capable of adjusting the draft to solve the problems of ships.
