- Abstract
- Ice resistance related to ship propulsion system was very close to power requirement of ship in icebreaking operation. Especially, most researchers separate ice resistance into several components with some physical background. In this study, we conducted the standard model ship in KORDI ice model basin. The ice resistance tests in level ice and pre-sawn ice were performed at the velocity of 0.238, 0.357 and 0.476 m/s (2, 3 and 4 knots in full scale). Towing force was assumed to represent the total resistance. Pre-sawn ice test was performed to calculate each resistance component in level ice. Measured ice resistance is corrected by ITTC method to compensate ice thickness and flexural strength. Finally, the corrected results were compared to those of the prediction.
