Abstract: A series of technical problems of “ice-breaking, winterization and scientific research” in the construction process of the “Xue Long 2” are summarized in order to systematically solve the bottleneck of Chinese polar ship construction technology in the future. The key points of the ice-breaking structure construction, the winterization design and the installation of the polar research equipment are reviewed from the construction process of the assembly plant, achieving technical breakthroughs in the construction of the polar research icebreaker. It also proposes the key points of structure construction technology optimization and winterization protection system design, and preliminarily set up the fine construction technology system for the polar research ship lifecycle. The advance research of the construction technology of a heavy icebreaker is also carried out to put forward further research interest.

Key words: Xue Long 2, polar research icebreaker, heavy icebreaker, winterization, construction technology

摘要： 为系统性解决未来中国极地船舶建造工艺瓶颈,该文总结了“雪龙2”号 建造过程中“冰、寒、科考” 的一系列工艺技术难题,从总装厂建造工艺出发,梳理了破冰结构建造、御寒技术设计及极地科考设备安装调试等方面的关键点,取得了极地破冰科考船建造关键技术的突破;提出了结构建造技术优化、防寒系统设计等方面要点;初步构建起面向极地破冰科考船全寿命周期的精细化建造工艺技术体系,并就重型破冰船开展了建造技术预研攻关,提出了下一步研究方向。
