Представлены обобщенные результаты доковых осмотров судов Дальневосточного морского бассейна. Приведены примеры и выполнен анализ характерных повреждений гребных винтов ледоколов и судов ледового плавания, а также условий, при которых они были получены. Рассмотрены требования Российского морского регистра судоходства (РС) к проектированию ледовых гребных винтов, характеристика возможных нагрузок на их лопасти. Приведен пример расчета усталостной прочности винтов ледокола с учетом рекомендаций РС и Шведско-финских правил для судов ледового плавания (Finnish-Swedish Ice Class Rules). This paper covers summarized results of dock inspections of vessels in the Far Eastern Sea Basin. Examples of typical damages of screw propellers of icebreakers and ice navigation vessels as well as critical conditions are duly presented. Requirements of the Russian Maritime Register of Shipping (RMRS) for the design of ice propellers and parameters of active loads for their blades are fully considered. The example of fatigue strength calculation of icebreaker propeller is given subject to the requirements by RMRS and Finnish-Swedish Ice Class Rules.
