scope:

This document addresses recommendations for subsea structures and manifolds, within the frameworks set forth by recognized and accepted industry specifications and standards.

Equipment within the scope of this document is listed below (see Figure 1):

a) the following structural components and piping systems of subsea production systems:

- production and injection manifolds,

- modular and integrated single satellite and multi-well templates,

- subsea processing and subsea boosting stations,

- flow control modules,

- flowline riser bases and export riser bases,

- pipeline end manifolds (PLEM),

- pipeline end terminations (PLET),

- T- and Y-connections,

- subsea isolation valves (SSIV);

b) the following structural components of subsea production system:

- subsea controls and distribution structures,

- other subsea structures;

c) protection structures associated with the above components;

d) foundations and mounting bases to support above structures;

The following components and their applications are outside the scope of this document:

- pipeline and manifold valves;

- flowline and tie-in connectors;

- choke valves;

- flow control valves;

- multi-phase flow meters;

- pressure vessels;

- production control systems.

NOTE General information regarding these topics can be found in additional publications, such as API 17A, API 17E, and API 2C.
