В последние годы в качестве альтернативы все чаще применяется полиэтилен низкого давления (ПНД). Данный материал характеризуется повышенной стойкостью к воздействию морской среды, полной перерабатываемостью, низкой плотностью и конкурентоспособной стоимостью. Однако исследования, посвященные технологии изготовления конструктивных элементов судов из ПНД, остаются фрагментарными. В настоящей работе представлен комплексный анализ процессов строительства судов из ПНД, охватывающий доступные производственные технологии. В статье детально рассмотрены технологии сварки, применяемые для соединения элементов корпуса. Кроме того, проведена критическая оценка преимуществ и ограничений ПНД в качестве конструкционного материала для судостроения. Результаты исследования способствуют формированию стандартизированных подходов к изготовлению маломерных судов из полиэтилена низкого давления.</p></abstract><trans-abstract xml:lang="en"><p>Most small vessels have been constructed using wood or fiberglass-/carbon fiber-reinforced polymer composite materials. Increasingly, low-pressure polyethylene, or high-density polyethylene (HDPE), has been adopted as an alternative material. It combines enhanced resistance to marine environments with full recyclability, as well as a low density and competitive price. However, research on producing vessel structural components from HDPE is limited. Thus, this study aims to thoroughly analyze the production processes for HDPE vessels, detailing available manufacturing technologies. In particular, the welding technologies used to join hull components are closely examined. Additionally, the advantages and limitations of applying HDPE as a structural material in shipbuilding are critically evaluated. Results from this study contribute to the development of standardized approaches for manufacturing small vessels from low-pressure polyethylene.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэтилен низкого давления</kwd><kwd>маломерные суда</kwd><kwd>конструктивные элементы корпуса</kwd><kwd>сварка полимеров</kwd><kwd>полимерные материалы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-pressure polyethylene</kwd><kwd>small vessels</kwd><kwd>hull structural elements</kwd><kwd>polymer welding</kwd><kwd>polymer materials</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The research team expresses its gratitude to Pavel I.
