During loading, cargo transferred on board adds weight to the vessel. De-ballasting removes some of the ship’s weight to lighten her, thus counterbalancing the added cargo weight. You can see this happen on some ships in port pumping out water from their sea side. They are most likely engaged in deballasting operation.
How does ballasting effect ship operation?
Ballast helps in immersing the rudder, supporting the manoeuvrability of the vessel and also reducing the exposed hull surface. The ship continually uses fuel and water from its tanks leading to weight loss. The ballast operation helps in compensating for the weight loss.
