Abstract: The characteristics of polar ship rules of China Classification Society have been analyzed by reviewing the current status of international conventions and rules of polar ships. The technical development trend of rules of polar ships is also summarized combining with the national polar strategy and development needs. Aiming at the important key technical issues of the ice-breaking technology, the winterization technology and the sailing safety supporting technology, the ice load technology of ship structure, the structural strength calculation under ice load, the propeller and shafting strength under ice load excitation, the winterization design and low temperature test verification of polar ships, the assessment of the polar operation capability, and the hull monitoring technology for operations in polar regions are introduced. The corresponding development suggestions are proposed to provide technical support for the independent establishment of China’s polar ship rule system in the future.

Key words: polar ship, rules, ice-breaking, winterization, sailing safety supporting

摘要： 通过梳理极地船舶国际公约、规范技术现状,分析中国船级社建立的极地航行船舶规范特点,并结合我国极地战略及发展需求,总结未来极地船舶规范的技术发展趋势。针对极地船舶破冰技术、防寒技术和航行及保障技术等重要关键技术问题,从船舶结构冰载荷技术、冰载荷作用下的结构强度计算、冰载荷激励下螺旋桨和轴系强度、极地船舶防寒设计与低温试验验证、极地操作能力评估和冰区操作船体监测技术等方面进行阐述,提出了发展建议,为未来我国极地船舶规范体系的自主构建提供技术支持。
