本文件规定了与北极和寒冷地区石油和天然气工业活动有关的海上结构物的设计、建造、运输、安装和退役的要求，并提供了建议和指导。本文件中提及的北极和寒冷地区被视为包括北极和其他环境温度低、存在或可能存在海冰、冰山、结冰条件、持续积雪和\/或永久冻土的地区。本文件的目的是确保北极地区和寒冷地区的完整结构，包括下部结构、上部结构、浮式生产船舶船体、基础和系泊系统，在人员安全、环境保护和资产价值方面提供适当的可靠性水平。价值包括对所有者、行业和整个社会的价值。本文件不包含北极和寒冷地区海洋结构物的操作、维护、使用寿命检查或修理要求，除非设计策略规定了诸如冰管理（IM）等减少冰作用的具体要求。ISO 19905-1和ISO 19905-3中给出了移动设备的操作、维护、使用寿命检查和维修规定，并补充了本文件中有关冰作用和IM的规定。本文件不适用于与北极和寒冷地区海上作业相关的机械、工艺和电气设备或任何专业工艺设备，除非结构物需要安全承受此类设备的安装、外壳和操作所施加的作用。本文件适用于用于定位和断开浮式结构物的设备（见第13条）。

This document specifies requirements and provides recommendations and guidance for the design, construction, transportation, installation and decommissioning of offshore structures related to the activities of the petroleum and natural gas industries in arctic and cold regions. Reference to arctic and cold regions in this document is deemed to include both the Arctic and other locations characterized by low ambient temperatures and the presence or possibility of sea ice, icebergs, icing conditions, persistent snow cover, and/or permafrost. The objective of this document is to ensure that complete structures, including substructures, topsides structures, floating production vessel hulls, foundations and mooring systems, in arctic and cold regions provide an appropriate level of reliability with respect to personnel safety, environmental protection and asset value. Value includes value to the owner, to the industry and to society in general. This document does not contain requirements for the operation, maintenance, service-life inspection or repair of arctic and cold region offshore structures, unless the design strategy imposes specific requirements such as ice management (IM) to reduce ice actions. Provisions for the operation, maintenance, service‐life inspection and repair of mobile units are given in ISO 19905-1 and ISO 19905-3, supplemented by the provisions relating to ice actions and IM in this document. This document does not apply to mechanical, process and electrical equipment or any specialized process equipment associated with arctic and cold region offshore operations except in so far as it is necessary for the structure to sustain safely the actions imposed by the installation, housing and operation of such equipment. This document applies to equipment used for the positioning and disconnection of floating structures (see Clause 13).
