This paper discusses and presents analysis work using the raw field data towards generating a continuous record of ice conditions. We present results towards automating the extraction...

..., attainable speed and powering in various ice conditions. Generally, one ice flexural strength and two or three different ice thickness values are used to predict the ice resistance/powering and attainable speeds in order to meet the vessel's mission profile. Outcomes of these tests are generally...

... ABSTRACT The continuous melting of Arctic sea ice has attracted increasing interest in the potential of navigation in the Arctic route. Most existing studies use the sea ice concentration (SIC) to evaluate the sea ice condition along the route. Based on the historical sea ice data (including...

On the basis...

... and calculating transportation cost. The most important part of transit analysis for ice-going vessels is the calculation of the parameters of the ship's movement (speed, power) in ice conditions.
