In this paper authors present results of numerical calculation of the ballast water exchange with a 2-Dimension tank model by using MPS method. In recent years discharged ballast water from the ships has been identified as a potential threat to the marine environment. Many kinds of species are included in discharged ballast water and these are transferred from one port to others. Breed species have some potential that cause severe adverse impact on ecology including expulsion of native organisms. It probably affects the human society as well. In view of this problem the IMO adopted "Regulations for the Control and Management of Ship's Ballast Water and Sediments" in 2004. In this treaty, It is required that ballast water and sediments contained in ballast water should be managed carefully. Authors have inspected the validity of the ballast water exchange with using pumping-through method that is one of the methods of ballast water management more, before. In this paper, the numerical simulation of the motion and concentration of the fluid at the time of exchange of the fluid in a 2-dimensional tank using the pumping-through method was carried out by using the MPS method that is one of the particle methods. Calculation results show that it is possible to simulate the movement of the fluid in a 2-dimensional tank using MPS method.
