Discharge of ballast water

The discharge of ballast water close to the coast is a potential environmental hazard. Organisms that are transported with the ballast water pass from one ecosystem to another and can cause great damage to the new environment.

Installation of ballast water treatment systems

To reduce the risk of impacts on local ecosystems, the UN International Maritime Organisation (IMO) has issued a ballast water management convention. The convention, which came into force in September 2017, aims to prevent alien organisms from being spread with ships’ ballast water. This applies to all vessels on international voyages that  take on and release ballast water. 

According to the Convention, all international traffic vessels are obliged to manage ballast water according to a ship-specific ballast water management plan. All vessels are required to keep a ballast water book and hold an international ballast water management certificate. The Convention also includes requirements for built-in ballast water  management systems that move or kill micro-organisms in the ballast water before it is released.

All Concordia Maritime’s vessels follow a Ballast Water Management Plan, based on existing guidelines. Several of the fleet vessels have already had special ballast water management systems installed.

In 2020, these systems were installed on a further two vessels. Other vessels in the fleet will have similar systems installed when they go into drydock in 2021 and 2022.
