When developing the design for a new icebreaker, it is important to know the benefits and penalties of different hull shapes as early as possible. Model experiments are on method of providing this information, but they can be time consuming to carry out. In order to improve the use of the model tank during concept development, it was necessary to increase the number of experiments which were carried out in a single ice sheet. This paper presents a methodology for carrying out resistance, self-propulsion for manoeuvring experiments in one ice sheets, and presents the results of some recent experiments for illustration and discussion purposes. Data on performance in calm water and head waves are also important for concept evaluation. Some results of experiments on several modem hull shapes are presented and compared. For predicting the performance of the final design in ice, more detained information on the effects of hull-ice friction and flexural strength are required. The paper presents some recent experiment methods and results which were used to correlate model results with ship trial data.
