标准范围

本文件为海上结构的上部结构的设计和制造提供了要求、指南和信息，包括在役、服役前和服役后条件。上部结构上的作用和结构部件中的作用效应来自本文件，必要时结合ISO 19901系列中的其他国际标准（例如，ISO 19901-1风作用-见7.6.2，ISO 19901-2地震作用-见7.7）和ISO 19902疲劳设计（见6.7）。本文件适用于以下情况:—？固定海上结构的上部结构；—？放置在浮动海上结构和移动海上单元的船体结构上的离散结构单元；—？北极近海结构的上部结构，不包括过冬（见ISO？19906）。如果上部结构的任何部分构成了抵抗全球平台作用的整体结构系统的主要结构的一部分，则本文件的要求由ISO中的适用要求补充？19902，ISO？19903，ISO？19904-1，ISO？19905-1，ISO？19905-3和ISO？19906.对于选择受公认船级社规则管辖的浮动海上结构和移动式海上装置的那些部分，相应的船级规则取代了本文件的相关要求。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。本文件的火灾和爆炸规定可适用于浮动结构和移动式海上装置的船体中包含碳氢化合物加工、管道或储存的部分。笔记？ISO 19901-9中提出了结构完整性管理的要求。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要和次要结构；—？耀斑结构；—？起重机基座和其他起重机支撑装置；—？直升机着陆甲板（helidecks）；—？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。本文件提供了选择和使用具有确定轧制和焊接非圆棱柱形构件及其连接阻力的对应系数的国家建筑标准的要求。

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.
