Description

The ballast system of a ship {Ballast System}

The present invention relates to a ballast system of a ship. More particularly, the present invention relates to a ballast tank provided with a ballast tank and an operation unit for supplying and discharging ballast water to and from the ballast tank, In addition, it is possible to operate the operation unit of the remaining part normally to operate the system normally, thereby further stabilizing the function of the ballast. By mounting the ballast water treatment device (BWTS) in each of the foreplay operation unit and the stern operation unit, Or even if a flooding accident occurs, it is possible to operate the ballast water treatment device of the remaining part in addition to the ballast water treatment device in the corresponding part to normally perform sterilization treatment on the ballast water, thereby providing a more stable ballast system of the ship.

In general, the ballast tank of a ship is to minimize the center of gravity of the ship by the loading and unloading of the cargo, thereby helping to enable safe navigation. In other words, if the cargo is loaded on the ship, the center of gravity of the ship is located below the sea level without filling ballast water in the ballast tank. Even if an external force such as waves acts, the ship can safely navigate. The ballast water is introduced into the ballast tank so that a certain part of the ship can be positioned below the sea level as the ship is shipped.

In addition, when the center of gravity of the ship is shifted to one side, the ballast water may be introduced into the ballast tank at a specific position to compensate the ballast water to maintain the equilibrium state of the ship.

In particular, a drill ship, such as a drill ship, which is held at a certain position is provided with a ballast system for inflowing and discharging ballast water or moving it to a specific ballast tank to maintain equilibrium of such a vessel.

The ballast system of the present invention includes an operation unit that operates to supply and discharge ballast water to and from the ballast tank, a main pipe connected to the operation unit to which the ballast water flows, and a plurality of branch pipes branched from the main pipe, And is composed of a plurality of sub-pipelines.

The operation unit includes a supply pump for supplying ballast water to the ballast tank and a discharge pump for discharging the ballast water from the ballast tank. The ballast water is supplied from the sea chest of the ship by the operation of the supply pump and supplied to the plurality of ballast tanks through the main piping and the sub piping. Similarly, by the operation of the discharge pump, the ballast water is sucked and discharged from the plurality of ballast tanks through the sub-pipe and the main pipe.

In a general ship according to the related art, in particular, in the case of a drill ship, an operation unit is provided in a machine room of a stern and a ballast water can be supplied and discharged from an operation unit provided at a stern to a portal ballast tank and a starboard ballast tank do.

In this way, since the operation unit of the ballast system is provided only at the stern, there is a problem that when the stern is flooded or a fire accident occurs, the operation unit can not be operated and the normal ballast system can not be operated.

In particular, recently, the International Maritime Organization (IMO) has been obliged to provide a ballast water treatment system (BWTS) for sterilizing harmful microorganisms contained in ballast water in the process of injecting and discharging the ballast water. Since the conventional ballast water treatment system according to the prior art is provided only at the stern together with the operation unit, the problem that the ballast water treatment apparatus can not be used at the same time in case of an emergency such as flood or fire accident have.
