Ballast water alternatives

To eliminate the introduction of foreign marine species which are nowadays the main concern and reason for the introduction of ballast treatment systems, a new concept in ship design was developed as an alternative. Most of them are still more theoretical than practical, except one concept. Scientist at the University of Michigan created “continuous flow” method as a replacement for the classic ship ballast. This concept is designed to replace double bottom tanks with the network of trunks running from bow to stern, below the waterline. The opening at the bow and stern allows water to pass through these channels which reduces ship buoyancy, instead of weighing it down.
