Scientific Analysis of the ASPPR Hybrid System for Type B Vessels

Significant research has 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 system. This report provides information on a proposed revised approach (Hybrid System) for dealing with Type B vessels in Canada’s Arctic waters. The proposed Hybrid System would redefine some of the existing Zone boundaries and allow mostly expanded windows for shipping using a combination of Ice Regime System Mandatory dates and Open Zone dates. The report is intended as a starting point for discussion with key Stakeholders of the ASPPR.
