Patent number: 10218247Abstract: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.Type: GrantFiled: June 3, 2015Date of Patent: February 26, 2019Assignee: General Electric CompanyInventors: Vittorio Michelassi, Siddharth Navinchandra Ashar, Ismail Hakki Sezal, Rene du Cauze de Nazelle, Egidio Marotta, Ravishankar Balasubramanian, Mohamed Osama

Patent number: 9574562Abstract: A pump for pumping a multiphase fluid includes a housing and a rotor with an outer surface. A plurality of inducer vanes are attached to the rotor hub, each having a leading edge and a trailing edge where the leading edge of one inducer vane overlaps the trailing edge of an adjacent inducer vane by a first overlap angle. A plurality of impeller vanes are also attached to the hub. The impeller vanes each have a leading edge and a trailing edge where the leading edge of one impeller vane overlaps the trailing edge of an adjacent impeller vane by a second overlap angle larger than the first overlap angle. The pump includes a rotor flow channel extending between the hub outer surface and the housing inner surface. The rotor flow channel has an inlet area and an outlet area, whereby the outlet area is smaller than the inlet area.Type: GrantFiled: August 7, 2013Date of Patent: February 21, 2017Assignee: General Electric CompanyInventors: Jeremy Daniel Van Dam, Vittorio Michelassi, Ismail Hakki Sezal, Xuele Qi, Rene du Cauze de Nazelle, Vishal Gahlot, Scott Richard Erler

Patent number: 9512700Abstract: A subsea fluid processing system is provided containing a liquid reservoir, an inlet tank, a pump, an outlet system, and a fluid re-circulation loop. The liquid reservoir circulates a primer liquid stream to the inlet tank via the fluid re-circulation loop. The inlet tank further receives a first production fluid stream and mixes it with the primer liquid stream to produce thereby a second production fluid stream having a reduced gas volume fraction (GVF) relative to the first production fluid stream. The pump receives the second production fluid stream from the inlet tank and increases its pressure. Further, the outlet system containing the liquid reservoir receives the second production fluid stream from the pump and separates at least a portion of the primer liquid stream from a principal production stream. The primer liquid includes at least one exogenous liquid not derived from the first production fluid stream.Type: GrantFiled: December 12, 2014Date of Patent: December 6, 2016Assignee: General Electric CompanyInventors: Guillaume Becquin, Siddharth Navinchandra Ashar, Jr., Vittorio Michelassi, Rosa Castane Selga, Rene Du Cauze De Nazelle
