Subsea hydraulic and pneumatic power
View Patent ↗Systems and methods for providing energy to sub-sea support equipment. Energy can be provided by diverting at least a portion of a fluid from a well producing system to sub-sea support equipment units that can be disposed in the vicinity of the sea-floor, sea-bed, or mud-line. The well producing system can include, but is not limited to, a water injection system, a gas lift system, or combinations thereof. A water injection system designed to provide pressure support to one or more wells can be modified to provide an operational power source to one or more sub-sea support equipment units.
1. A method for providing power to sub-sea support equipment units, comprising:
diverting at least a portion of a pressurized fluid used by a well producing system, wherein the diverted fluid defines a diverted fluid energy source; and
providing the diverted fluid energy source to a sub-sea support equipment unit for use as an operational power source, wherein the sub-sea support equipment unit is disposed in the vicinity of a mud-line,
wherein the support equipment unit performs at least one processing step on a hydrocarbon, and
wherein the at least one processing step on the hydrocarbon comprises dehydration, sulfur removal, or a combination thereof.
2. The method of claim 1 , wherein the operational power source comprises one or more direct mechanical links.
3. The method of claim 2 , wherein the one or more direct mechanical links connect to a plurality of sub-sea support equipment units.
4. The method of claim 1 , wherein the operational power source is electricity generated by converting the diverted fluid energy source into electrical energy.
5. The method of claim 4 , further comprising providing at least a portion of the electricity to a plurality of sub-sea support equipment units for use as an operational power source.
6. The method of claim 1 , wherein the support equipment unit supports the lifting of a hydrocarbon to above a water line.
7. The method of claim 6 , wherein the support equipment unit performs the processing step prior to supporting the lifting of the hydrocarbon to above a water-line.
8. The method of claim 1 , further comprising converting the pressurized fluid energy source into electricity.
9. The method of claim 8 , further comprising providing the electricity to a plurality of sub-sea support equipment units, wherein the plurality of sub-sea support equipment units are disposed in the vicinity of the mud-line.
10. The method of claim 1 , further comprising providing the diverted fluid energy to a plurality of sub-sea support equipment units, wherein the plurality of sub-sea support equipment units are disposed in the vicinity of the mud-line.
11. The method of claim 1 , wherein the pressurized fluid used by the well producing system is introduced into a well.
12. The method of claim 1 , wherein the pressurized fluid used by the well producing system is introduced into a well to support lifting a production product to above a mud-line.
13. The method of claim 1 , further comprising introducing a second portion of the pressurized fluid to the well producing system while the at least a portion of the pressurized fluid is diverted.
14. The method of claim 1 , further comprising recovering the diverted fluid energy source from the sub-sea support equipment and introducing at least a portion of the recovered diverted fluid energy source to a well.
15. A method for providing power to sub-sea support equipment units, comprising:
diverting at least a portion of a pressurized fluid used by a well producing system, wherein the diverted fluid defines a diverted fluid energy source; and
providing the diverted fluid energy to a plurality of sub-sea support equipment units for use as an operational power source, wherein the plurality of sub-sea support equipment units are disposed in the vicinity of a mud-line, wherein the operational power source is direct mechanical power, and wherein at least one support equipment unit supports the lifting of a hydrocarbon to above a water line,
wherein the support equipment unit performs at least one processing step on a hydrocarbon, and
wherein the at least one processing step on the hydrocarbon comprises dehydration, sulfur removal, or a combination thereof.
16. A system for providing power to sub-sea support equipment units, comprising:
means for converting at least a portion of a fluid source used by a well finishing system into an energy source suitable for providing power to a sub-sea support equipment unit disposed in the vicinity of a mud-line, and
means for providing the energy source to the sub-sea support equipment unit,
wherein the support equipment unit performs at least one processing step on a hydrocarbon, and
wherein the at least one processing step on the hydrocarbon comprises dehydration, sulfur removal, or a combination thereof.
17. The system of claim 16 , wherein the energy source suitable for providing power to a sub-sea support equipment unit comprises one or more direct mechanical links.
18. The system of claim 16 , wherein the energy source suitable for providing power to a sub-sea support equipment unit is electrical energy.
19. The system of claim 16 , wherein the support equipment unit supports the lifting of a hydrocarbon to above a water line.
20. The system of claim 16 , wherein the support equipment unit performs at least one processing step on a hydrocarbon.
21. The system of claim 16 , wherein the support equipment unit performs the processing step prior to supporting the lifting of the hydrocarbon to above a water-line.
22. The system, of claim 16 , further comprising means for providing the energy source to a plurality of support equipment units.
