Subsea multiphase pump or compressor with magnetic coupling and cooling or lubrication by liquid or gas extracted from process fluid

This is an underwater pump or compressor designed to handle mixtures of liquids and gases. It uses an electric motor to spin a rotor, which is supported by bearings. The system uniquely separates liquid from the multiphase fluid it's processing and uses that extracted liquid to lubricate and cool its own bearings, ensuring the liquid is at a lower temperature than the bearings.

Why it matters: Filed before significant advancements in real-time fluid analysis sensors and predictive control algorithms. These now enable more precise and reliable management of the extracted process fluid for bearing lubrication and cooling in subsea environments.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSubsea pressure housing, fluid separator, custom bearings.
