What is a ship’s ballast tank ?
A ballast tank is a large water tank designed to be filled with sea water to optimise navigation, and provide stability for a vessel.
Ballast water treatment
When ballast water is pumped into a ship, microorganisms are discharged into the ballast tanks. Many of these organisms can survive in these tanks and when the ballast water is discharged, the organisms are released into new environments. Under favorable conditions, these species survive, reproduce, and become marine invasive species.
The loading and unloading of untreated ballast water thus poses a significant threat to the environment, public health and the economy.
