In response to the threat of invasive marine species, Sweden-based Kockum Sonics AB has developed a new concept for safe and efficient ballast water exchange on high seas. The concept is based on their two products LoadRite and Levelmaster - as exchanging ballast water in deep water requires careful planning. LoadRite, with its full 3-D description of the hull, is being used for hydrostatic calculations. It has been developed further to include the powerful Ballast Exchange Support Tool for the ship officers to define the fastest and safest way of ballast exchange at sea. A simulation of the complete ballast exchange process is followed by an online supervision in real-time as well as predicting future conditions.
