The reduction of ice cover and increased activities related to maritime transport and exploiting natural resources in the arctic regions in recent decades have resulted in increased interest and demands for developing ice-capable vessels to navigate along Arctic shipping routes. Among these routes, the Northern Sea Route (NSR), which tails along the Russian coast, presents a potential shortcut for connecting the Europe and East Asia. Ice conditions are considered as the key factors for design of Arctic ships since they are closely related to the ship ice loads and structural response. In this work, four representative sites along the NSR are selected to study the ice conditions along the NSR. Specifically, ice thickness is estimated by applying the accumulated freezing degree days (FDD) method based on the collected air temperature records. A scheme which consists of the ice thickness, ice temperature, ice salinity and porosity is introduced in this work in order to estimate the ice flexural strength and crushing strength. Finally, a comparison is made to evaluate the severity of ice conditions at the four representative sites selected along the NSR.
