本推荐规程（RP）在公认和公认的行业规范和标准规定的框架内，解决了水下结构物和歧管的具体要求和建议。因此，它不会取代或消除任何其他行业规范施加的任何要求。本RP涵盖了用于水下油气生产和水下注入服务中的压力控制的水下歧管和模板。本RP范围内的设备包括:生产和注射歧管；模块化和集成的单卫星和多井模板；水下处理站和水下增压站；出油管立管底座和出口立管底座（FRB、ERB）；管道端歧管（PLEM）；管道终端（PLET）；T型和Y型连接；海底隔离阀结构（SSIV）；水下控制和分配结构； 以及相关的保护结构。

This recommended practice (RP) addresses specific requirements and 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.This RP covers subsea manifolds and templates used for pressure control in both subsea production of oil and gas, and subsea injection services. Equipment within the scope of this RP includes: 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- connections; subsea isolation valve structures (SSIV); subsea controls and distribution structures; and associated protection structures.
