Implementation of Ballast Water Management Plan in Ships Through Ballast Water Exchange System

open access: yesProcedia Engineering, 2017
Abstract In this paper, sequential method has applied for ballast water exchange of ships. Moreover, a model has been developed in Maxsurf to carry out the sequential method. The sequential method is a process by which a ballast tank intended for the carriage of ballast water is first emptied and then refilled with replacement ballast water to ...
