Qualified for use Subsea
Transvac Ejector Solutions have successfully achieved 'Technology Readiness Level 7' status. This is the highest quality assesment to attain, meaning our Ejectors are fully proven in a Subsea production field environment.
Transvac supplied two Ejectors to Petrobras' Marlim field, which is located in Campos Basin, Brazil at a water depth of 870m.
Why choose Ejectors for Subsea Processing?
With no moving parts and no maintenance Transvac’s Ejector technology is an ideal solution for subsea processing. To ensure trouble-free operation, all Transvac subsea Ejectors are designed, manufactured and tested in-house. Operating rotating mechanical equipment subsea requires huge amounts of energy, often megawatts of power. Ejector technology can operate using existing energy and therefore operating costs can be negligible. Rotating mechanical equipment also requires special designs for performing subsea. Ejector designs change very little whether subsea or topside. In some applications, Ejector flows can be simply calculated using pressure drop data across the Ejector, thereby negating the need for flow metering instrumentation.
Materials of construction and mechanical design meet project specific subsea piping standards and are fully qualified. Transvac also provides ceramic nozzle and diffuser components for abrasive applications which have been proven over many years on topside applications.
Typical Subsea Ejector Applications
- Hydrocyclone pressure boosting
- Enhanced Oil/Gas Recovery
- Multi-phase fluid pumping
- Separator flushing
- Sand slurry pumping
- Sand cleaning
- Micro-bubble generation for conditioning process water
- Flow Restrictor / Pressure let-down
Transvac supplied the world’s first subsea processing Ejector on the TORDIS project for Statoil.
