API - RP 17L2

Recommended Practice for Ancillary Equipment for Flexible Pipes and Subsea Umbilicals

active, Most Current
Organization: API
Publication Date: 1 June 2021
Status: active
Page Count: 286
scope:

This RP provides guidelines for the design, materials selection, analysis, testing, manufacture, handling, transportation, installation, and integrity management of ancillary equipment for flexible pipes and umbilicals. It supplements API 17L1, which specifies minimum requirements for the design, material selection, manufacture, documentation, testing, marking, and packaging of the ancillary equipment.

This RP presents the current best practice for design and procurement of ancillary equipment and gives guidance on the implementation of the specification for standard ancillary products. In addition, this RP presents guidelines on the qualification of prototype products.

The applicability relating to a specific item of ancillary equipment within this RP is stated at the beginning of the section dedicated to that item of ancillary equipment.

This RP applies to the following ancillary equipment:

- bend stiffeners;

- bend restrictors;

- bellmouths;

- buoyancy modules and ballast modules;

- subsea buoys;

- tethers for subsea buoys and tether clamps;

- riser and tether bases;

- clamping devices;

- subsea buoy clamps

- piggy-back clamps;

- repair clamps;

- I/J-tube seals;

- pull-in heads/installation aids;

- connectors;

- load-transfer devices;

- mechanical protection;

- fire protection;

- VIV suppression strakes.

This document may be used for bonded flexible pipe ancillary equipment, though any requirements specific to these applications are not addressed.

Where relevant, the applicability of recommendations to umbilicals is indicated in the applicability section for the ancillary equipment in question.

This RP does not cover ancillary equipment for flexible pipes and umbilicals beyond the connector, with the exception of riser bases and load-transfer devices. Therefore, this document does not cover turret structures or I-tubes and J-tubes, for example. In addition, it does not cover flexible pipe or umbilical storage devices, for example reels.

This RP is intended to cover ancillary equipment made from several material types, including metallic, polymer and composite materials. It may also refer to material types for particular ancillary components that are not commonly used for such components currently but may be adopted in the future.

This RP applies to ancillary equipment used in association with the flexible pipe and umbilical applications listed in API 17B, API 17J, API 17E, and API 17K.
