Comparative Study on Resistance Performance of Icebreaking Cargo Vessel according to Hull Form Variation by using Synthetic Ice and Refrigerated Ice

The present paper deals with the comparative study of resistance performance with refrigerated ice and synthetic ice according to the variation of hull form characteristics. The resistance test has been conducted in pack ice condition in each concentration condition. Stem angle has been chosen as main parameters for the variation of hull form characteristics. The correlation of performance between with th e refrigerated ice and with the synthetic ice has been shown according to the variation for stem angles. The present study show the possibility of ice test in general towing tank with synthetic ice for the time-consuming research such as hull form optimization although that is confined in pack ice condition. The more parametric study for the properties of synthetic ice is expected to be conducted to have more close correspondence for the test results of refrigerated ice in near future. ※Keywords: Towing tank(), Ice tank(), Icebreaking cargo vessel(), Synthetic ice(), Refrigerated ice(), Stem angle()
