Рассматриваются суда, предназначенные для транспортировки сжиженного природного газа наливом. Числовые параметры, характеризующие тепловой поток, используют для определения интенсивности образования отпарного газа: газа, который испаряется с поверхности груза в процессе транспортировки, и определения расчетной температуры смежных с грузовой емкостью корпусных конструкций. В статье выполнены тестовые расчеты теплового потока для трех судов-газовозов. Два судна оборудованы мембранными емкостями общей грузовместимостью 361000 м3 и 172000 м3 соответственно. Третье тестовое судно оборудовано двумя емкостями типа С вместимостью по 2900 м3 . Выполнены расчеты для стандартных параметров окружающей среды в соответствии с требованиями отраслевых нормативных документов, проведена оценка адекватности полученных результатов и модели в целом. Выполнены количественные и качественные оценки влияния параметров окружающей среды на параметры теплового потока. Результаты, представленные в статье, могут быть использованы при совершенствовании требований нормативных документов и разработке конструкции системы хранения сжиженного газа.</p></abstract><trans-abstract xml:lang="en"><p>The aims of the article is to describe and demonstrate the practical application of analytical heat flow calculation in ship hull and thermal insulation of liquefied gas carriers. Numerical parameters describing the heat flow are used to calculate the amount of boil-off gas evaporating from liquefied gas surface in tank. Also, such numerical parameters are used to define the design temperature of hull structures adjacent to gas containment system. The article gives the results of test heat flow calculations for three ships. Two of the ships are equipped with membrane containment system and have the total cargo capacity of 361000 m3 and 172000 m3 , respectively. The third test ship is equipped with two type C tanks of 2900 m3 capacity each. The calculations corresponding to the standard environment conditions as per industry normative documents have been performed. Reliability of the results, as well as the mathematical model itself, has been checked. Case studies have been done to assess the influence of external conditions to heat flow parameters, both numerically and qualitatively. The results given in the article may be used to improve the requirements of normative documents, and in practical cargo containment system design.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газовоз</kwd><kwd>тепловой поток</kwd><kwd>отпарной газ</kwd><kwd>мембранная технология</kwd><kwd>емкость типа C</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas carrier</kwd><kwd>heat flow</kwd><kwd>boil-off gas</kwd><kwd>membrane technology</kwd><kwd>type C tank</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">Бойко М.С.
