石油和天然气工业 - 北极海上结构

[中文适用范围]： 本文件规定了与北极和寒冷地区石油和天然气工业活动相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。 本文件中提到的北极和寒冷地区被认为包括北极和其他以低环境温度以及存在或可能存在海冰、冰山、结冰条件、持续积雪和/或永久冻土为特征的地点。 本文件的目的是确保北极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水平的可靠性。 价值包括对所有者、对行业和整个社会的价值。 本文件不包含北极和寒冷地区海上结构物的运行、维护、使用寿命检查或维修要求，除非设计策略提出了诸如冰管理（IM）等特定要求以减少冰作用。 文件中给出了移动装置的操作、维护、使用寿命检查和维修的规定。 本文件不适用于机械、过程和电气设备或与北极和寒冷地区海上作业相关的任何专用过程设备，除非结构有必要安全地承受安装、容纳和操作所施加的作用。 这样的设备。 本文件适用于用于浮动结构的定位和断开的设备（见第 13 条）。 [外文原描述]： 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).
