| 20100294317 | Separation Vessel for Solids Removal - A separation device for removing solids from an input stream is provided, comprising a vessel, such as a production vessel or storage tank, having an inlet for receiving an input stream containing fluids, such as oil and water, and solids, such as sand and silt. The vessel also includes a fluid outlet and a drain outlet. An optional fluid recirculation and injection device is mounted inside the vessel and delivers fluid to facilitate removal of the solids through the drain outlet. The vessel also includes an agitation or flighted device mounted adjacent to the drain outlet for contacting and dislodging solids which have settled within the vessel. The agitation device includes a rotatable shaft driven by a motor, and an agitation element, such as an auger, to break up the solids and move them toward the drain outlet. A method of removing solids is also provided using the auger device. | 11-25-2010 |

| 20110155384 | SUBSEA FLUID SEPARATOR - The present application is directed to a subsea separator. The subsea separator suitably comprises (a) a housing having an inlet for receiving a fluid mixture, a non-gaseous fluid outlet located along the housing at a point lower than the inlet, and a gas outlet located along the housing at a point higher than the inlet; (b) a deflector means located within the housing for acting on fluid entering the housing; and (c) a sealing means in communication with the gas outlet for preventing non-gaseous fluid from exiting the housing through the gas outlet, the sealing means being operationally configured to open and seal the gas outlet based on the volume of non-gaseous fluid within the separator; wherein the separator is operationally configured to operate under a differential pressure including a greater external hydrostatic pressure than internal pressure and vice versa. | 06-30-2011 |
| 20110158824 | SUBSEA TECHNIQUE FOR PROMOTING FLUID FLOW - The present application is directed to a submersible pumping system operable under hydrostatic pressure. The system suitably comprises a prime mover submersible within a first fluid; a pump means submersible within the first fluid and sealably coupled to the prime mover; and a fluid source in fluid communication with the prime mover, the fluid source providing a second fluid effective to act on the prime mover to power the pump means; wherein the second fluid is discharged in the first fluid after acting on the prime mover; and wherein the second fluid has a chemical composition substantially similar to the first fluid. | 06-30-2011 |
