Forecasting the propulsion of a cargo-passenger ferry when moving in broken ice

The results of experimental studies of the ice propulsion of the CNF22 project passenger-and-freight ferry model are given in the article. The vessel has a bulbous bow, a transom stern and is designed for the class of the Russian Maritime Register of Shipping with ice reinforcements Ice2. The choice of the broken ice model is justified in the article. The resistance curves of the vessel model in clear deep water and in broken ice 0.5 m thick with ice concentration of 4, 6, 8 points when moving bow and stern forward were obtained. An algorithm for recalculating test results from a model to a full-scale vessel is presented. The propulsion of the vessel when moving on clear water and in broken ice is predicted.
