Ballasting or de-ballasting is a process by which sea water is taken in and out of the ship when the ship is at the port or at the sea. The sea water carried by the ship is known as ballast water.

Ballast or ballast water is sea water carried by a vessel in its ballast tanks to ensure its trim, stability and structural integrity. Ballast tanks are constructed in ships with piping system and high capacity ballast pumps to carry out the operation.

In ancient times, ships used to carry solid ballast for stability as the cargo was minimal or there was no cargo to be carried. However, as time passed difficulties were faced during loading and discharging of solid cargo. The process of transferring of solid cargo was also time-consuming and for this reason solid ballast was replaced by water ballast. As sea water was readily available and in huge amount, it was used for the ballasting and de-ballasting process.

Ballasting or de-ballasting is required when the ship is to enter a channel, cross any canal likePanama canal and Suez Canal, during loading or unloading of cargo, and when ship is going for berthing.

Ballasting and De ballasting Simplified

When no cargo is carried by the ship, the later becomes light in weight, which can affect its stability. For this reason, ballast water is taken in dedicated tanks in the ship to stabilize it. Tanks are filled with ballast water with the help of high capacity ballast pumps and this process is known as Ballasting.

Lastrado o deslastrado es un proceso mediante el cual se toma agua de mar dentro y fuera de la nave cuando el barco está en el puerto o en el mar. El agua de mar que llevaba el buque se conoce como agua de lastre.

Lastre o lastre de agua es agua de mar realizada por un buque en sus tanques de lastre para asegurar su asiento, la estabilidad y la integridad estructural. Tanques de lastre se construyen en los buques con sistema de tuberías y bombas de alta capacidad de lastre para llevar a cabo la operación.

En la antigüedad, los buques utilizados para llevar el lastre sólido para la estabilidad como la carga fue mínima o no había carga a transportar. Sin embargo, como las dificultades de tiempo pasado se enfrentaron durante la carga y descarga de mercancías sólido. El proceso de transferencia de la carga sólida era también consume tiempo y por esta razón lastre sólido fue sustituido por agua de lastre. Como el agua del mar era de fácil acceso y en gran cantidad, que fue utilizado para el proceso de lastrado y deslastrado.

Lastrado o se requiere de-lastre cuando el buque es entrar en un canal, cruzar cualquier canal de como canal de Panamá y el Canal de Suez , durante la carga o descarga de mercancías, y cuando la nave se va para el atraque.

Cuando no hay carga es transportada por el buque, la tarde se convierte en luz en el peso, lo que puede afectar su estabilidad. Por esta razón, el agua de lastre se toma en los tanques dedicados en la nave para estabilizarlo. Los tanques se llenan de agua de lastre con la ayuda de bombas de lastre de alta capacidad y este proceso se conoce como Lastrado .
