Subsea pumping systems (tentative recommended practice)
|Publication Date:||1 September 2019|
This recommended practice specifies normative and informative technical requirements for the whole subsea pumping system with pressure ratings up to 1035 bar (15 000 psi) and water depths down to 3000 m (9843 feet) for the following pump types:
- single phase
The pump types are used for modular based mudline pumping systems for:
- single pump stations
- dual pump stations
- pumps integrated in subsea production systems
- pumps integrated in subsea processing systems
- water injection
- dual/coupled lifts.
The requirements are organized in the following eight main sections:
- This section contains the introduction, objective, scope, application, references, definitions and abbreviations.
- Sec.2 contains information about subsea pumping system elements and building blocks.
- Sec.3 contains functional, design and technical requirements for the subsea pumping system.
- Sec.4 contains minimum requirements for the qualification of pump units to technology readiness level (TRL) 4 and TRL 5, provides guidance for reuse the of qualified technology.
- Sec.5 contains minimum requirements for inspection and test plans for TRL greater than or equal to 4.
- Sec.6 contains requirements for the minimum test scope for TRL greater than or equal to 5.
- Sec.7 contains requirements for marine operations and IMR.
- Sec.8 contains guidance on documentation for the subsea pumping systems.
This recommended practice has the status of tentative due to reference to the ballot edition of API RP 17X. Until the official version of API RP 17X is issued, requirements or references to the ballot edition of API RP 17X should not be used as a contractual basis. Other requirements in this RP may be used independently of API RP 17X. When API RP 17X is published, this document will be updated and reissued as a new edition.
This recommended practice is intended to serve as a contractual document between the parties. The defined requirements in this recommended practice come in addition to the requirements in the referenced international standards.
The document has been written for general, world-wide application. Governmental regulations may include requirements exceeding those given in this recommended practice. If there is a conflict between the requirements stated in this recommended practice and governmental regulations, then the governmental regulations shall apply. For topics outside the defined scope, it is up to the end-user to evaluate if other standards or requirements are applicable. Such applications may include:
- pump types
- electrical submersible pumps (ESP)
- downhole (in-well) pumps
- caisson pumps
- data network security
- cyber security
- foundation structure.
This document is not intended to inhibit a supplier from offering, or an operator from accepting, alternatives to that described in this document. This can be particularly applicable where there is innovative or developing technology. Where an alternative is offered, it is the responsibility of the supplier to identify any variations from this document and provide details to the operator.
Subject to agreement between contracting parties, this document may also be used for other than subsea applications.
