石油和天然气行业 包括低碳能源

[中文适用范围]： 本文件提供了海上结构上部结构设计和制造的要求、指导和信息，包括服役中、服役前和服役后的情况。上部结构的作用和结构部件的作用效应均源自本文件，必要时可与 ISO 19901 系列中的其他国际标准结合使用（例如设计（见 6.7）。本文件适用于以下情况： — 固定式海上结构物的上部； — 放置在浮动式海上结构物和移动式海上设施船体结构上的离散结构单元； — 北极海上结构的上部，不包括防冬（见 ISO 19906）。如果上部结构的任何部分构成抵抗全球平台作用的整体结构系统的主要结构的一部分，则本文件的要求将通过 ISO 19902、ISO 19903、ISO 19904-1、ISO 19905-1、ISO 19905-3 和 ISO 19906 中的适用要求进行补充。对于选择由公认船级社规则管辖的浮动式海上结构物和移动式海上设施的那些部件，相应的船级社规则取代本文件的相关要求。本文件还涉及火灾、爆炸和其他意外事件的预防、控制和评估。本文件中有关火灾和爆炸的规定可适用于包含碳氢化合物加工、管道或储存的浮动结构和移动式海上设施的船体部分。注：结构完整性管理的要求在 ISO 19901-9 中给出。本文件适用于包括以下内容的结构部件： - 甲板、模块支撑框架和模块中的主结构和次结构； - 火炬结构； - 起重机基座和其他起重机支撑装置； - 直升机停机坪； - 独立海上结构之间的永久桥梁； - 海上结构上的桅杆、塔架和吊杆。1 本文件提供了选择和使用国家建筑标准的要求，以及用于确定轧制和焊接非圆形棱柱形部件及其连接件的抗力对应系数。 [外文原描述]： This document provides requirements, guidance and information for the design and fabrication of topsides structure for offshore structures, including in-service, pre-service and post-service conditions. The actions on topsides structure and the action effects in structural components are derived from this document, where necessary in combination with other International Standards in the ISO 19901 series (e.g. ISO 19901-1 for wind actions - see 7.6.2, ISO 19901-2 for seismic actions - see 7.7) and ISO 19902 for fatigue design (see 6.7). This document is applicable to the following: — topsides of fixed offshore structures; — discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units; — topsides of arctic offshore structures, excluding winterization (see ISO 19906). If any part of the topsides structure forms part of the primary structure of the overall structural system which resists global platform actions, the requirements of this document are supplemented with applicable requirements in ISO 19902, ISO 19903, ISO 19904-1, ISO 19905-1, ISO 19905-3 and ISO 19906. For those parts of floating offshore structures and mobile offshore units that are chosen to be governed by the rules of a recognized classification society, the corresponding class rules supersede the associated requirements of this document. This document also addresses prevention, control and assessment of fire, explosions and other accidental events. The fire and explosion provisions of this document can be applied to those parts of the hulls of floating structures and mobile offshore units that contain hydrocarbon processing, piping or storage. NOTE Requirements for structural integrity management are presented in ISO 19901-9. This document applies to structural components including the following: — primary and secondary structure in decks, module support frames and modules; — flare structures; — crane pedestal and other crane support arrangements; — helicopter landing decks (helidecks); — permanent bridges between separate offshore structures; — masts, towers and booms on offshore structures. This document provides requirements for selecting and using a national building standard with a correspondence factor for determining the resistance of rolled and welded non-circular prismatic components and their connections.
