The Canadian Hydraulics Centre of NRC has been working with Transport Canada to put the Arctic Ice Regime Shipping System (AIRSS) on a scientific basis. This work is being done using empirical data in a pragmatic manner. An extensive database has been developed that provides information on vessel damage and non-damage over a wide range of ice and environmental conditions. An analysis has been performed with this data to check the current definition of the Ice Numeral. It has been found that although the system reasonably well reflects the observations, there are numerous instances where the agreement is poor. An advanced scheme has been proposed for discussion. This approach takes into account the “interaction” aspects of vessels in ice-covered waters. Using this approach, a significant improvement in the definition of the Ice Numeral can be achieved.
