| Summary: | The present paper reports on comparisons between results from ice basin tests and numerical simulations. The tests were conducted in the model ice basin of the National Research Council Canada (NRC) in St. John's, Newfoundland. Those tests examined the Dynamic Positioning (DP) of a vessel in managed ice conditions at a scale of 1:40. A numerical model, which was developed by the NRC over the past few years, was used to simulate ice basin test conditions. The results indicate that surge direction thrust and moments are in good agreement. The conclusions address the effects of ice channel width and floe shapes. Peer reviewed: Yes NRC publication: Yes |
