A SCALING SYSTEM FOR VESSELS MODELED IN ICE

This paper present the rationale and the technique used to derive an equation that can be utilized to scale the results of resistance model tests run in ice to the full scale regime. The equation was obtained, utilizing stepwise multiple regression analysis techniques on model and full scale data available for five different icebreaking vessels. The results indicate that full scale resistance can be predicted to within 10 percent of measured prototype values. The technique is applicable to homogeneous ice sheets under neutral pressure conditions, i.e., no adverse pressure fields exist. The effect of the coefficient of friction is also taken into account.
