PURPOSE: A ballast tank structure for a ship is provided to adjust stable draft by controlling the supply or discharge of seawater when cargo is loaded or unloaded on a ship. CONSTITUTION: A ballast tank structure for a ship comprises an inlet part(11) and an outlet part(12). Seawater continuously flows in and out through the inlet part and the outlet part when cargo is loaded and unloaded in ballast tanks. The ballast tanks are connected to a pipeline to inject air pressure into the ballast tank with a pump. Accordingly, the seawater is pushed to make space part for loading the cargo. |
