Важнейшим составляющим данного параметра является ледопроходимость судна — способность преодолевать лед предельной толщины на устойчивой скорости движения 2 — 3 уз при работе энергетической установки на режиме максимальной мощности. Ледопроходимость зависит от целого перечня факторов, среди которых основные — ледовое сопротивление движению, тяга движительного комплекса и мощность энергетической установки.Данная работа является первой частью исследования, посвященного разработке рекомендаций по выбору существующих расчетных методов определения ледового сопротивления движению судна в сплошном ровном льду. Несмотря на обширный накопленный опыт и отработку ряда расчетных методик, необходимо отметить ограниченные возможности их применения. Причина данных ограничений заключается в несовершенстве разработанных математических моделей взаимодействия корпуса судна с ледяным покровом, а также в несоответствии применяемых эмпирических коэффициентов современным проектам судов. При этом различные методики имеют отличающиеся по точности результаты расчетов применительно к судам разных классов и размерений. Это также обусловливается спецификой используемых математических моделей и количеством учитываемых факторов.В работе проводится анализ и систематизация сценариев взаимодействия корпусов судов различного типа со сплошным ледяным покровом. Далее, рассматриваются существующие расчетные методики определения ледового сопротивления и приводится их SWOT-анализ. Во второй части исследования предполагается привести данные по верификации рассмотренных методов данными экспериментальных исследований. На основании полученных результатов будут сформированы рекомендации по выбору расчетных методик в зависимости от ледовых условий, типа судна и формы его корпуса.Исследования, направленные на повышение точности прогнозирования значений ледового сопротивления на предварительных этапах проектирования, являются актуальными и могут значительно снизить финансовые и трудовые затраты проектных организаций.</p></abstract><trans-abstract xml:lang="en"><p>In the process of designing ice-going ships and icebreakers, one of the key tasks is to determine the parameters of their ice-going capabilities, i.e. the ability to overcome ice of maximum thickness at a steady speed of 2—3 kt when the power plant is operating at maximum power. Ice-going capabilities depend on a whole range of factors, the most important of which are ice resistance, thrust of the propulsion system and the power of the power plant.This work is the first part of a study focused on the development of recommendations for the selection of existing computational methods for determining the ice resistance to ship movement in level ice. Despite the extensive accumulated experience and the development of a number of calculation methods, their application is limited. The reason for these limitations lies in the imperfection of the developed mathematical models of the interaction of the ship's hull with the ice cover, as well as in the inconsistency of the applied empirical coefficients with modern ship designs. At the same time, it should be noted that different methods have different calculation results in terms of accuracy for ships of different classes and sizes. This is also due to the specifics of the mathematical models used and the number of factors considered.The paper analyzes and systematizes scenarios of interaction between the hull of a vessel of various types with a level ice. Next, the existing computational methods for determining ice resistance are considered and their SWOT analysis is provided. In the second part of the study, it is proposed to provide data on the verification of the considered methods by experimental research data. Based on the results obtained, recommendations will be formed on the choice of calculation methods depending on ice conditions, the type of vessel and the shape of its hull. Research aimed at solving the problem of improving the accuracy of forecasting ice resistance values at the preliminary stages of design is relevant and can significantly reduce the financial and labor costs of design organizations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ледовое сопротивление</kwd><kwd>ровный лед</kwd><kwd>ледокол</kwd><kwd>судно ледового плавания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ice resistance</kwd><kwd>level ice</kwd><kwd>icebreaker</kwd><kwd>ice-going ship</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ионов Б.П.
