Строящаяся ледостойкая самодвижущаяся платформа (ЛСП), согласно проекту, должна быть оборудована такой системой, которая, во-первых, является основной системой обеспечения безопасности работы платформы в ледовых условиях, во-вторых, делает сам корпус платформы уникальным инструментом решения широкого комплекса задач по изучению воздействия льда на сооружения.</p><p>В рамках экспедиции выполнялись измерения напряжений, возникающих в корпусе НЭС «Академик Трёшников» во время ледовых воздействий, с целью получения необходимых данных для разработки системы мониторинга ледовых нагрузок строящейся ЛСП и апробации прототипа СМЛН в условиях дрейфа.</p><p>Были проанализированы данные, полученные при движении судна в ледовых условиях во время выполнения набегов, а также во время дрейфа. Анализ данных позволил выделить ряд особенностей для эксплуатации СМЛН в условиях дрейфа, которые будут учтены при реализации проекта СМЛН ЛСП.</p><p>Конфликт интересов отсутствует.</p></abstract><trans-abstract xml:lang="en"><p>At present, oil-producing offshore structures, as well as transport vessels transporting oil products extracted in the seas of the Russian Arctic are equipped with ice load monitoring systems (ILMS) to prevent environmental disasters. The ice-resistant self-propelled platform (IRSPP) that is under construction now, according to the design should be equipped with this system. First of all this system is the main system for ensuring the platform’s safety in ice conditions, and secondly makes the platform’s hull a unique tool for solving a wide range of tasks to study the effects of ice on any construction.</p><p>The main goal of the research during the expedition “Transarktika-2019” was to obtain the necessary data for the development of an ice load monitoring system of the constructing IRSPP “North Pole” and testing the prototype of the ILMS at long vessel’s drift in ice.</p><p>The measurements of stresses in the hull structures of the R/V “Akademik Tryoshnikov” were carried out during impacts on ice ridges and during ice compressions.</p><p>The standard ship ice load monitoring system (SILMS) of the R/V “Akademik Tryoshnikov” and strain gauges additionally installed on the frames and a shell plating in the middle part of the hull were used to perform the measurements.</p><p>The analysis of the obtained data showed that the maximal loads on the hull occurred during the forcing of ice ridges but the level of maximum stresses was not a danger to the hull.</p><p>Compressions during the drift did not have a strong effect on the ship’s hull. The data obtained made it possible to identify a number of features for the operation of ILMS in similar conditions.</p><p>Based on the results of the expedition research, recommendations for the design of the architecture of the ILMS for IRSPP were issued. The results of further analysis of the obtained materials will be used in the development of data processing algorithms for ILMS for IRSPP, as well as for the development of the prospective programs of scientific research of deformation, fracture and other processes of various scales that occur in drifting ice during the future drifts of the IRSPP “North Pole”.</p><p>The authors have no competing interests.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инженерные сооружения</kwd><kwd>ледовые нагрузки</kwd><kwd>ледостойкая платформа</kwd><kwd>ледовые условия</kwd><kwd>система мониторинга</kwd></kwd-group><kwd-group xml:lang="en"><kwd>engineering structures</kwd><kwd>ice conditions</kwd><kwd>ice loads</kwd><kwd>ice-resistant platform</kwd><kwd>monitoring system</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Все исследовательские работы и логистика экспедиционного проекта ТРАНСАРКТИКА 2019 финансировались Росгидрометом.
