本文件规定了管道系统整个生命周期的完整性管理要求，并给出了建议，包括设计、施工、调试、运行、维护和废弃。 本文件适用于输送石油和天然气的海上管道。适用于刚性钢质管道。它不适用于柔性管道、动态立管或由玻璃钢等其他材料制成的立管。 注1:海上管道系统延伸至: -平台水上的第一个阀门、法兰或接头，或具有水下结构（即歧管或动态立管）的水下机械接头； -海上装置的连接点（即不包括管道歧管）； -除非陆上法规另有规定，否则陆上第一个阀门、法兰、连接或隔离接头。 注2:上述部件（阀门、法兰、连接件、隔离接头）还包括任何短管件，即。 e、 海上管道系统延伸至短管外的焊缝，见图1。 本文件用于管道设计和施工阶段的完整性管理。如果设计和施工标准（如ISO 13623）的要求不同，本文件的规定将从完整性角度加强设计和施工。

This document specifies requirements and gives recommendations on the management of integrity of a pipeline system throughout its life cycle, which includes design, construction, commissioning, operation, maintenance and abandonment. This document is applicable to offshore pipelines for transporting petroleum and natural gas. It is applicable to rigid steel pipelines. It is not applicable to flexible pipelines, dynamic risers or those constructed from other materials, such as glass-reinforced plastics. NOTE 1 An offshore pipeline system extends to: — the first valve, flange or connection above water on platform or subsea mechanical connector with subsea structure (i.e. manifold or dynamic riser); — the connection point to the offshore installation (i.e. piping manifolds are not included); — the first valve, flange, connection or isolation joint at a landfall, unless otherwise specified by the onshore legislation. NOTE 2 The components mentioned above (valve, flange, connection, isolation joint) include also any pup pieces, i.e. the offshore pipeline system extends to the weld beyond the pup piece, see Figure 1. This document is used for integrity management, which is initiated at the design and construction stage of the pipeline. Where requirements of a design and construction standard (e.g. ISO 13623) are different, the provisions of this document will enhance the design and construction from an integrity perspective.
