Latest update: New recommended practice now publishedAs a result of this JIP, a new DNV GL recommended practice (RP) - DNVGL-RP-F303 Subsea pumping systems - has now been published. This RP provides a comprehensive specification for subsea pumping systems and complements existing industry standards. Access the RP.
Background for the JIP
Our industry is looking towards standardization for ensuring cost efficient and reliable technology. Subsea processing is a relatively young field of technology, but over the recent years, experience has grown significantly with developments as Total’s Pazfloor project, Petrobras’ Marlim project and Statoil’s Troll Pilot, Tordis, Åsgard and Gullfaks.
Equal to more conventional solutions, subsea processing must prove to be cost efficient to be considered attractive. At the same time, subsea processing will be an enabler for increased oil recovery.
To address the above, this DNV GL JIP works towards standardization of subsea processing, starting off with subsea pumping.
The objective of the JIP is to reduce cost in a lifetime perspective for subsea processing. The JIP will initially focus on subsea pumping.
Phase 2: Guideline for subsea pumping
Building on Phase 1, the JIP will continue with development of detailed descriptions of standardized solutions for subsea pumping. The strategy for Phase 2 will be to gradually progress the standardization work for subsea pumping from requirements on system level towards development of more detailed descriptions.
The scope for Phase 2 is defined in the document ‘Plan for Standardization’ that was developed in Phase 1 of the JIP. The plan describes a list of activities with defined deliverables that will feed into the contents of the guideline. The intention is to issue the guideline as a DNV GL Recommended Practice for industry use.
Phase 2 activities are related to:
- Standards, functional requirements and specifications
- System design
- Pump modules and pressure containing equipment
- Control system and instrumentation
- Power system
- Materials and welding
- Qualification work processes and test requirements.
Phase 1: Alignment and definition
Phase 1 lasted from December 2015 – December 2016 and delivered ‘Functional description for subsea pumping’ and ‘Plan for Standardization’ (scope for Phase 2). Four operators and two suppliers participated in Phase 1: FMC, OneSubsea, Petrobras, Shell, Statoil and Woodside.
