Description

Purge system for water ballast tank

The present invention relates to a purge system of a ballast tank, and more particularly, to fill / discharge gas and fill / inert gas by installing a vent for purge pipe having a drain hole by pipe connection to the base of the ballast tank. A purge system of a ballast tank that can reduce the evacuation time.

In general, the ballast tank of the ship is to help the safe navigation by minimizing the variation in the center of gravity of the ship by loading and unloading the cargo.

In other words, if the vessel is loaded with cargo, the center of gravity of the vessel is located below the sea level even if the ballast tank is not filled with the number of ballasts. In the same way that the cargo is loaded, the ballast water is introduced into the ballast tank so that a certain portion of the ship is located below the sea level.

In particular, oil drilling rigs, floating oil refineries, and special vessels should be operated with rehabilitation safety when petroleum drilling, oil refining, and separation operations are carried out at sea. Height) maintenance is required.

In addition, to maintain the safety of restoring the draft by adjusting the draft even during emergencies due to bad weather during long-distance navigation. When a draft is required or when adjustment is required, several horizontal ballast tanks or vertical ballast tanks are pumped into the seawater and conditioned by emptying them.

At this time, the air should be freely discharged and introduced through the air vent for smooth filling and discharge when filling or emptying the tank with seawater.

In order to perform this function, as shown in FIG. 1, the ballast tank 10 has an air vent head 12 and an air vent head 12 for discharging air in the ballast tank 10. An inert gas connection 14 is provided for filling and discharging the inert gas. Reference numeral 16 denotes a cargo oil tank.

However, it is possible to fill and discharge the inert gas in the ballast tank 10 through the equipment provided on the ballast tank 10, that is, the air vent head 12 and the inert gas connection 14. The disadvantage is that the filling and discharging time of the inert gas is too long.
