Выполнены численные оценки устойчивости положения судна в канале, результаты которых позволили объяснить механизм нарушения симметрии. Выполнены приближенные оценки ледового сопротивления крупнотоннажного судна при несимметричном движении по каналу, показавшие повышенную эффективность такого движения по сравнению с симметричным случаем.</p></abstract><trans-abstract xml:lang="en"><p>This work investigates a previously unknown phenomenon taking place when a large carrier ship moves in a channel made by an icebreaker narrower than the carrier ship. Usually, the studies of these movement conditions assumed the center line of the ship to coincide with the channel axis and the interaction of ship sides with channel edges to be symmetric. However, the observations made in Ice Basin and in real conditions have shown that in most of cases interaction of ship sides with channel edges is not symmetric. The ship moving in the channel breaks ice only with one of her sides, the other side only rubbing against the edge. The numerical assessments of ship position stability in the channel given in this paper made it possible to understand how this interaction becomes asymmetric. The study also yielded ice resistance assessments for a large carrier ship moving along the channel in these asymmetric conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крупнотоннажное судно</kwd><kwd>ледовое сопротивление</kwd><kwd>ледовый канал</kwd><kwd>устойчивость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Arctic</kwd><kwd>ice channel</kwd><kwd>ice resistance</kwd><kwd>large ship</kwd><kwd>stability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ФГУП «Атомфлот» за стимуляцию исследовательских работ по обеспечению проводки крупнотоннажных судов ледоколами; Российский научный фонд, проект № 17-79-20162</funding-statement><funding-statement xml:lang="en">FSUE Atomflot for encouragement of research studies on icebreaker-assisted operation of large-size vessels in Arctic waters; RSF, project No.17-79-20162</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рукша В.В., Головинский С.А., Белкин М.С.
