Abstract: The equipment on weather deck of polar ships, especially high polar-ice-class icebreakers, should withstand extremely low design service temperatures. The steering gear and bow thrusters should also consider the additional requirements for ice loading. The input requirements for the equipment design are analyzed from the rules of main outfitting equipment such as the lifesaving equipment, deck machinery and manoeuvring devices. The equipment configuration and location of the high polar-ice-class ships that were delivered at home and abroad are analyzed to provide references for the localization of main outfitting equipment in the future.

Key words: high polar-ice-class icebreaker, lifesaving equipment, deck machinery, manoeuvring device, localization

摘要： 极地船舶（尤其是高冰级破冰船）的露天设备需要承受极低的设计服务温度,其舵机和侧推装置需要满足附加冰载荷要求。该文从救生设备、甲板机械和操纵设备等舾装主要设备的规范角度,分析设备设计输入要求,结合国内外已交付高冰级破冰船的设备配置及布置位置分析,为今后舾装主要设备国产化提供参考和借鉴。
