Abstract:
A unique low cost and efficient submersible, hermetically sealed, variable speed system intended to drive submersible boosting units. The system includes a unique combination of a liquid filled electrical motor connected to a hydraulic coupling and a magnetic coupling driver section, in a hermetically sealed container, with a magnetic coupling follower driving a booster unit. The system further includes integrated cooling, lubrication and control functionality. The drive unit has an actuating system connected to internal guide vanes which controls the liquid flow between the pump impeller and turbine wheel of the hydrodynamic coupling and hence the torque and speed. The combined system is a sealed seal-less and topside-less submersible drive unit that can operate in harsh subsea environments. The drive unit opens up for use of thin walled pressure casings and low pressure electrical penetrators.

Claim (Index 25):
A boosting system for subsea use comprising:\n an enclosed shell divided into a sealed motor compartment and a booster unit compartment by a pressure containment member; the motor compartment containing an electric motor having a shaft, a hydrodynamic coupling, and a driver portion of a magnetic coupling, a liquid fluid filling the motor compartment, the liquid fluid being a combined coolant, lubricant and. hydrodynamic coupling fluid; the booster unit compartment containing a booster unit having a shaft operably connected to a follower portion. of the magnetic coupling, the magnetic coupling follower portion being separated from the driver portion by the pressure containment member; and a pressure compensating device for balancing the pressure in the motor compartment with an external subsea pressure.
