DHI Ballast water Centre

The International Maritime Organization (IMO) has adopted the International Convention for the Control and Management of Ship’s Ballast Water and Sediments to reduce the risk of spreading harmful aquatic organisms and pathogens released with ballast water. The convention requires that all ships install Ballast Water Management Systems (BWMS) to treat the ballast water before it is released to the environment.

For verification of BWMS performance DHI has build up a land-based test facility using natural freshwater, brackish and high saline seawater at Hundested Harbour in Denmark .
