Omnirise Singlephase Boosting Pump, without Barrier Fluid and with internal Variable Speed Drive

Pumps can increase oil recovery from existing fields with 10-30 % and are considered an excellent tool for increasing profits with minimal environmental impact. For example, 1 % increased recovery from a field in the Norwegian continental shelf represents more than 100 billion NOK in increased revenue to Norway (based on an oil price at 30 USD/barrel). However, only 18 of ca. 1600 offshore fields have installed rotating subsea equipment. Why is this? The main obstacle to increased proliferation of this type of equipment is high costs (equipment and installation) combined with sub-optimal reliability. FSubsea's Omnirise Booster, will be the worlds most autonomous boosting system and be a true enabler of «Lean Subsea Field Development». The system removes the need for several hundred tonns of topside equipment as well as an expensive hydraulic umbilical line. Furthermore, it is the first "green"-rated subsea pump module in the world, as it has a hermetically sealed barrier towards the ocean. This will significantly limit undesired spills of chemicals into the ocean.

The project has developed a seal-less and topside-less subsea pump technology that greatly reduces cost and environmental impact in IOR developments. This seal-less technology is the only globally available subsea boosting system rated “GREEN” by the Norwegian Pollution Control Authority, as it is not releasing any harmful substances to the oceans. Furthermore, elimination of mechanical seals also eliminates the need for large and costly barrier fluid systems. This, coupled with the integration of speed control directly in the subsea pump unit, reduces the overall CO2 footprint of the system compared to conventional systems in a lifecycle perspective. The product developed allows FSubsea to offer cost competitive green technology via any EPC company, or directly to the end-user, to support the business case of brown field and green field development.
