ISO 13628-15:20 11在公认和接受的行业规范和标准规定的框架内提出了海底结构和管汇的建议。因此，它不取代或消除任何其他行业规范强加的任何要求。 ISO 13628-15:20 11涵盖了用于海底石油和天然气生产以及海底注入服务中压力控制的海底管汇和模板。 以下设备属于ISO 13628-15:20 11的范围: 海底生产系统的结构部件和管道系统，包括 生产和注入歧管， 模块化和集成的单卫星和多孔模板， 海底处理和海底升压站， 出油管立管底座和出口立管底座（FRB、ERB）， 管道末端歧管（PLEM）， 管道末端终端（PLET）， T-和Y-连接，以及 海底隔离阀（SSIV）； 海底生产系统的结构部件，包括 海底控制和分配结构以及其他海底结构，以及 与上述相关的保护结构。 ISO 13628-15:20 11不适用于管道和歧管阀、流线和接头连接器、节流阀和生产控制系统。

ISO 13628-15:2011 addresses recommendations for subsea structures and manifolds, within the frameworks set forth by recognized and accepted industry specifications and standards. As such, it does not supersede or eliminate any requirement imposed by any other industry specification. ISO 13628-15:2011 covers subsea manifolds and templates utilized for pressure control in both subsea production of oil and gas, and subsea injection services. The following equipment falls within the scope of ISO 13628-15:2011:

• structural components and piping systems of subsea production systems, including
  • production and injection manifolds,
  • modular and integrated single satellite and multiwell templates,
  • subsea processing and subsea boosting stations,
  • flowline riser bases and export riser bases (FRB, ERB),
  • pipeline end manifolds (PLEM),
  • pipeline end terminations (PLET),
  • T- and Y-connection, and
  • subsea isolation valve (SSIV);
• structural components of subsea production system, including
  • subsea controls and distribution structures and other subsea structures, and
  • protection structures associated with the above.

ISO 13628-15:2011 is not applicable to pipeline and manifold valves, flowline and tie-in connectors, choke valves and production control systems.
