Pack ice 상태에서의 합성얼음을 이용한 자항시험기법 연구

The previous study about self-propulsion test with synthetic ice for the Canadian Coast Guard icebreaker should that there were some difference between the tests with a synthetic ice and a refrigerated ice. In the present study, the density of synthetic ice is varied to have more interactive between the hull and ices which might make a more towing force than the previous case. The experimental work with refrigerated ice for the present model ship is expected to be conducted to compare in near future.
