Abstract
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.
Claims19
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.
12) 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;
- 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.
13) A method 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.
