Статистические характеристики вероятности встречи со льдом рассчитаны на основе обработки данных спутниковых наблюдений за период стандартной климатической нормы 1991-2020 гг. Установлено, что при следовании судов по Западному маршруту протяженность пути с вероятностью встречи со льдом более 50% и наиболее сложными ледовыми условиями (сплоченность 9-10 балов, торосистость 2 балла, толщина льда до 50 см) в период максимального развития ледяного покрова (февраль-март) составляет ~ 390 морских миль, что на ~50 морских миль больше, чем при следовании судов по Восточному маршруту. In this report we estimate the probability of ice encounter for ships traveling from the port of De-Kastri to the countries of Southeast Asia along two routes. Those routes were identified as the Western route and the Eastern route. The statistical characteristics of ice encounter probability were calculated based on the processing of 30-year observation series during the period of the standard climatic normal of 1991-2020. As a result of data analysis, we established that during the period of ice extent maximum development, that is February and March, the length of Western route came to approximately 207 nautical miles. Not only that was 20 miles longer compared to the Eastern one, but the route also had some quite harsh characteristics. Those included not only ice encounter probability of more than 50%, but also some of the most challening ice conditions, such as ice concentration of 9 to 10 points, hummocking of 2 points and ice thickness of up to 50 cm.
