中文摘要：

冰区航行船舶由于其特殊的工作环境与气候条件,其设计要求与传统的推进系统有着很大的不同。针对冰区航行条件下船舶推进系统所需要面临的问题,及这些问题所导致的冰区推进系统的特殊性进行了整理和分析,指出了推进系统设计过程中为应对冰区航行条件下的海冰、低温以及空泡噪声等问题所应采取的改进措施,为冰区航行船舶推进系统的设计提供了参考。

英文摘要：

Since of the special operating environment and climate condition, the design of ice-class propulsion system is much different from traditional propulsion system. For the specificity of ice-class propulsion system resulted by these problems, this thesis points out the measures to manage with the ice, low temperature, cavitation and noise, giving reference to the design for the propulsion system of ice-going ships.
