DEVELOPMENT OF OPTIMUM HULL FORMS FOR ICEBREAKING CARGO SHIPS FOR THE NORTHERN SEA ROUTE
A joint study on hull forms for ice-going merchant ship for the Northern Sea Route (NSR) has been underway since 1993 in Japan. An extensive model test program is being carried out using a series of icebreaking hull forms (three bow forms and two stern forms). To investigate the propeller-ice interaction effect, an open-type propeller and a ducted propeller were designed and model testes for comparison in identical conditions. The models were in turn tested in three different tanks under nominally similar model test conditions and with similar test methods but in three different types of model ice. Tests in clear water tanks were also conducted to evaluate the propulsion and seakeeping performance of the different models in open seas. The study was meant not only to contribute to the establishment of a quantitative database with which future NRS merchant ships can be optimized but also to provide reliable experimental data which would facilitate practical inter-tank comparison of ice modelling techniques in Japan. The study is on- going and this paper outlines the study program, the model hull form selection and the model tests results obtained at one of the ice model basins.
