Special Notes

API publications necessarily address problems of a general nature. With respect to particular circumstances, local, state, and federal laws and regulations should be reviewed.

Neither API nor any of API’s employees, subcontractors, consultants, committees, or other assignees make any warranty or representation, either express or implied, with respect to the accuracy, completeness, or usefulness of the information contained herein, or assume any liability or responsibility for any use, or the results of such use, of any information or process disclosed in this publication. Neither API nor any of API’s employees, subcontractors, consultants, or other assignees represent that use of this publication would not infringe upon privately owned rights.

API publications may be used by anyone desiring to do so. Every effort has been made by the Institute to assure the accuracy and reliability of the data contained in them; however, the Institute makes no representation, warranty, or guarantee in connection with this publication and hereby expressly disclaims any liability or responsibility for loss or damage resulting from its use or for the violation of any authorities having jurisdiction with which this publication may conflict.

API publications are published to facilitate the broad availability of proven, sound engineering and operating practices. These publications are not intended to obviate the need for applying sound engineering judgment regarding when and where these publications should be utilized. The formulation and publication of API publications is not intended in any way to inhibit anyone from using any other practices.

Any manufacturer marking equipment or materials in conformance with the marking requirements of an API standard is solely responsible for complying with all the applicable requirements of that standard. API does not represent, warrant, or guarantee that such products do in fact conform to the applicable API standard.

Recommended Practice for Flowline Connectors and Jumpers

1 Scope

This recommended practice (RP) addresses specific requirements and recommendations for subsea flowline connectors and jumpers 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 flowline connectors and jumpers used for pressure containment in both subsea production of oil and gas, and subsea injection services. Equipment within the scope of this document is listed below.

• Equipment used to make the following subsea connections are included:

  
  

  • pipeline end terminations to manifolds,

    
    

  • pipeline end terminations to trees,

    
    

  • pipeline end terminations to riser bases,

    
    

  • manifolds to trees,

    
    

  • pipeline inline sleds to other subsea structures.

    
    

• The following connection components and systems are included:

  
  

  • jumper assemblies,

    
    

  • monobore connectors systems,

    
    

  • multibore connectors systems,

    
    

  • pressure and flooding caps,

    
    

  • connector actuation tools.

    
    

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

    
    

• subsea structures,

  
  

• hydraulic, electrical, and fiber optic flying leads,

  
  

• umbilicals,

  
  

• pig launcher/receiver equipment,

  
  

• specialized ROV and other tooling.

Equipment for use in high-pressure high-temperature (HPHT) environments is beyond the scope of this document (see API 17TR8 for guidance on subsea HPHT applications).
