Ballast water convention by International Maritime Organization (IMO) focuses on reducing the transit of sediments and microorganisms of one territory to another through the ballast of ships. In order to prevent this condition, plans of making a “No Ballast Ships” is in progress. A no ballast ship or similar system can drastically reduce this problem. The concept has potential to lessen the problem of ballast water disposal which causes discharge of non-native species and creates several ecological problems. The design has a network of longitudinal pipes from bow to stern in ship’s hull causing a constant flow of local seawater which prevents the transfer of contaminated water or water from one ecosystem to other.
