Why do submarines have ballast tanks?
To control its buoyancy, the submarine has ballast tanks (see picture) that can be filled with water or filled with air. When the submarine is on the surface, the ballast tanks are filled with air. This makes the submarine’s density less than the density of the water.
How does a submarine ballast tank work?
At the surface the ballast tanks are emptied to give positive buoyancy. As air escapes from the tank, the vessel’s buoyancy decreases, causing it to sink. For the submarine to surface, the crew shuts the vents in the top of the ballast tanks and releases compressed air into the tanks.
Do submarines have bilge pumps?

Why do boats have a bilge?
The bilge is the lowest inner part, or bottom point, on a boat, and is designed to collect excess water. On vessels of virtually any size, a pump inside the bilge performs a very important function: to remove accumulated water by creating pressure or suction so that the water can be removed.
