Buoyancy adjustment chambers
Ballast tanks are compartments in ships and submarines that hold water to control buoyancy and stability.
Filling the tanks makes a vessel heavier and lower in the water; emptying them raises it.
Submarines use ballast tanks to dive and surface.
Cargo ships adjust ballast to compensate for varying loads: The tanker took on ballast water after offloading its crude.
