Ballast system

The ballast system is a water displacement system and is mainly used in ports and shipyards to alter ballast.

Ballast is generally the water in which the ship floats, such as sea water, pumped into ballast tanks. These ballast tanks are connected to pumps that pump water in or out. Crews fill these tanks to add weight to the ship and improve its stability.

Ballast tanks are also integral to the stability and operation of offshore deep water oil rigs and floating wind turbines
