Выполнен обзор существующей отраслевой нормативной базы, включая Правила Российского морского регистра судоходства, требования Международной ассоциации классификационных обществ, Международной морской организации, Финско-шведской морской администрации, Береговой охраны США. Выполнены расчеты температуры на основе анализа открытой отечественной базы данных измерений с 2013 по 2024 гг. в зимний период для точек наблюдения в восточной части Балтийского моря (Финский залив) и на Северном морском пути. Проведено сопоставление значений температур, полученных по разным методикам. Приведены результаты применения методов теории вероятностей и математической статистики для определения значения расчетной температуры воздуха. Определены параметры нормального закона распределения расчетной температуры для рассмотренных точек наблюдения, получены вероятностные оценки требуемых значений температуры.</p></abstract><trans-abstract xml:lang="en"><p>   The object of the study presented in the paper are the structures of ship hull subjected to the long-term influence of low ambient air temperature.</p><p>   The subject of the study are the methods aimed to define the value of design air temperature required to select the steel grade for hull structures.</p><p>   The methods addressed in the paper are based on the industry regulatory framework. The following requirements have been reviewed: rules of Russian Maritime Register of Shipping, International Association of Classification Societies, International Maritime Organization, Finnish-Swedish Maritime Administration, and US Coast Guard rules. The calculations of design temperature have been performed, which are based on the available Russian climate database for several observation points. The calculations cover the period of 2013—2024 for winter season in the eastern part of Baltic Sea (Gulf of Finland) and Northern Sea Route area. The comparison is made between different probability theory methods and statistics applied to define the value of design air temperature. Normal law parameters have been calculated for all the selected observation points. Eventually, the design temperatures have been calculated which are based on probability theory methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>корпус судна</kwd><kwd>низкая температура воздуха</kwd><kwd>Балтийское море</kwd><kwd>Северный морской путь</kwd><kwd>суда ледового класса</kwd><kwd>MDAT</kwd><kwd>DAT</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ship hull</kwd><kwd>low ambient temperature</kwd><kwd>Baltic Sea</kwd><kwd>Northern Sea Route</kwd><kwd>ice class ships</kwd><kwd>MDAT</kwd><kwd>DAT</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">Правила классификации и постройки морских судов.
