ICEBREAKING MODEL TESTS ORDERED BY THE U.S. MARITIME ADMINISTRATION FROM WARTSILA SYSTEMATIC VARIATION OF BOW LINES AND MAIN DIMENSIONS OF HULL FORMS SUITABLE FOR THE GREAT LAKES

The objective of the work in the laboratory is to simulate all possible existing ice conditions and to test ship models under these conditions. Thus the work is concentrated on practical questions and not on fundamental investigations which belong to the work of universities and other institutions of public ownership. However, since this kind of testing work is of a very recent date, many problems to be solved were faced before the practical testing could be started and thus the WIMB has performed some fundamental research work as well. Tests of ships in level ice fields and ridges under external pressure are being planned. In the future the work will be extended to cover the measurement of the ice pressure on the hull of the model.
