Outline of Final Research Achievements

The aim of this research is to develop the model ship test in an ice sea using synthetic ice and towing tank instead of using the refrigerated ice and ice tank. A synthetic ice made by a polypropylene (PP) plate with similar density of refrigerated ice are used in the ice resistance test in pack ice. The model test using PP ice was validated by the comparison with the ice resistance formula in pack ice. The synthetic ice made by a wax is developed for the model ship test in level ice. It was confirmed that the wax ice has a similar density and icebreaking of refrigerated ice. The icebreaking of the wax ice has to be validated quantitatively in order to accomplish the model test in level ice using synthetic ice and towing tank (future work).
