ResumoWhen freezing is present on ballast water, it can impose additional loads on the hull and effect on stabilization of ship.The anti-icing techniques of ballast water, therefore, are key criteria for ship safety.The existing anti-icing techniques of ballast tank are hull heating, water circulation and air bubble system etc.In this research, anti-icing performance tests for the ballast water using micro-bubble system and sea water circulation system have been carried out at two temperature conditions(-10℃ and -25℃).Ambient temperature, sea water temperature and temperature of the inner parts of the ballast tank are measured and also ballast water conditions are checked during the model test.The applied anti-icing techniques of ballast water, such as micro-bubble system and sea water circulation system show good performance in the low temperature conditions.
