SEMI-EMPIRICAL ICE RESISTANCE MODEL, VOLUME 1: MAIN REPORT

The report summarizes a project performed jointly by ARCTEC CANADA Limited and its U.S. associate, ARCTEC, Inc., in which an advanced computer based mathematical model was developed which predicts the resistance of an icebreaking ship in level ice. A very large data base of physical model and full scale icebreaker resistance data was compiled on which to base the empirical coefficients in the model. A brief explanation of the derivation of the math model basis is given. A description of the results of optimization of empirical data is provided, and advice on its applicability to determining thrust requirements is given. The accuracy and sensitivity of the mathematical resistance prediction is examined and presented. The volume of the report documents the procedures used for estimating ship resistance, assembly, and selecting of data base, developing the analytical model and finally the various phases of data analysis, discussions, and prediction methods of minimum thrust requirements.
