ASSESSMENT OF ICE MODEL TESTING TECHNIQUES

Ice model testing has extended beyond its traditional use for predictions of ship resistance and powering to include ship manoeuvring performance and ramming interaction, and forces on various offshore structure configurations. The modelling requirements posed by the different tests are described, and the possibilities given by the present model ice versions are indicated. Ice resistance, propeller-ice interaction, manoeuvring, ramming, and offshore structure tests are analyzed in detail. The modelling of the compressive strength of ice is identified as the major drawback in similitude. Comparison between full scale and model scale results show that the ice resistance and manoeuvring of ships is modelled adequately, as is the ice behaviour around offshore structures. The tests to obtain the maximum forces on structures leave some room for improvement.
