An R&D project of a cargo ship for the Northern Sea Route (NSR) was carried out in Japan for the period of 1993-1995. In the first year of the project a preliminary design of the NSR cargo ship was made. The designed ship was 180 m in overall length, 24 m in width and 8 m in full loaded depth. The vessel was designed to have a 24,000 HP powered single propeller to go through the ice up to 1,2 m thick in the continuous ice-breaking mode . A series of model tests followed the preliminary design to find the optimum hull form for the NSR cargo ship. Models of various hull forms, four forms for the bow and three for the stern, were designed and tested. Both the conventional and ducted propellers were tested. Resistance test, self-propulsion test and turning test were carried out in level ice sheet. Models were also tested in ridged ice and in water. Based on test results, evaluations were made for the hull forms to find the optimum one.
