ОN REGISTRATION OF ICE NAVIGATION RISKS ALONG THE NORTHEAST PASSAGE

The article is dedicated to the problem of registering the quality of ice navigation safety along the Northeast Passage and contains methodical recommendations for risk registration. Informational entropy of random events is accepted as quantitative estimate of risk of icy obstacles. Based on the work classification [5] the calculations risk values of statistic models for icy obstacles is given. Options of minimum the risks of unpredicted encounters through improved accuracy of messages are discussed. These measures may allow to create a database of ice obstacle risks which can serve as a basis for navigation risks estimate. The recommendations can be implemented in estimates and forecasts of expenditures on safety in ice navigation.
