[0002] The ship's ballast water system mainly consists of ballast water pumps, ballast water pipelines, ballast tanks, and related valves. The system's functions are: to inject or drain ballast water into the ship's ballast tanks according to the ship's operational needs, in order to adjust the ship's draft and the longitudinal and transverse stability and safe metacentric height; to reduce hull deformation to avoid excessive bending moments and shear forces, reduce hull vibration; and to improve the seaworthiness of empty tanks.

[0003] Application number CN201820354425.6 discloses a self-controlled anti-roll device for ship ballast tanks.
