Load-Varying Methods for Ship Power Estimation in Brash Ice Channel by Ice Tank Model Test

A series of ice tank tests of a bulk carrier was conducted at National Maritime Research Institute. According to the Finnish-Swedish Ice Class Rules, 1m thick brash ice channel was assumed as actual condition for ice class IA vessel and simulated in the ice tank. For the propulsion tests, two kinds of load-varying methods i.e. in brash ice and in open water, were employed. The difference in thrust at self propulsion point between these two methods was 8.1% at most, while RMSE of measurement in brash ice was 15.1%. The power required for 5knots in brash ice were estimated and compared with the rule-based calculation.
