| Abstract | Research and recent international initiatives have shown that Transport Canada’s Arctic Shipping Pollution Prevention Regulations (ASPPR) need to be modified and updated. The Canadian Hydraulics Centre of the National Research Council of Canada has been conducting research on methods to improve and update the two navigation control systems contained in the ASPPR. NRC-CHC undertook research leading to a revised approach (Hybrid System) to navigation control and applied this approach to a Type B vessel to illustrate the Hybrid System. Numerous comments were received on this by all key Stakeholders of the ASSPPR. This report documents the detailed ice severity for all 16 zones in the ASPPR throughout the winter for three Type vessels (E,B,A) and five Polar Class vessels (PC7,6,5,4,3). The information can be used as input into revising the Canadian Arctic shipping regulations. It provides a solid scientific basis for these regulations. |
