In recent years, Samsung Heavy Industries Company has been devoting its wide activities to the better performance of ice breaking vessels under the circumstance of rapid growth of Arctic markets. For economic operation, two different fore body and aft body for both ice and open performance evaluations are presented in this paper. The major objective of this study is the suggestion of the optimum ice breaking hull form according to its operation condition. The open and ice performance of the icebreaking vessel was validated at Samsung Ship Model Basin and Aker Arctic Technology Inc., respectively. From the present study, it has been found that the hull form optimized at extreme ice condition gave about 40.0% improved power performance at 1.67M level ice condition and about 10.0% inferior propulsion at open condition compared to the hull form with ice breaking bulbous bow. This paper describes the basis of hull form design and propulsion system including the performance evaluation results for ice breaking vessel.
