Abstract
An electrical power system for a resource extraction system includes a thermoelectric generator assembly configured to couple to a wall of a fluid containment structure. A portion of the thermoelectric generator assembly is configured to be disposed within an opening in the wall that extends through the wall to a cavity within the fluid containment structure. In addition, the thermoelectric generator assembly includes a thermoelectric generator configured to be in thermal communication with a fluid within the opening and with an environment external to the fluid containment structure. The thermoelectric generator is configured to generate electrical power in response to a temperature differential between the fluid within the opening and the environment.
Claims18
An electrical power system for a resource extraction system, comprising:
- a thermoelectric generator assembly configured to couple to a wall of a first fluid containment structure, wherein a portion of the thermoelectric generator assembly is configured to be disposed within an opening in the wall that extends through the wall to a cavity within the first fluid containment structure, the thermoelectric generator assembly comprises a thermoelectric generator configured to be in thermal communication with a fluid within the opening and with an environment external to the first fluid containment structure, and the thermoelectric generator is configured to generate electrical power in response to a temperature differential between the fluid within the opening and the environment and is configured to provide the generated electrical power to power a first electrical device of the first fluid containment structure and a second electrical device of a second fluid containment structure.
A resource extraction system, comprising:
- a first fluid containment structure having a wall and a cavity formed at least in part by the wall, wherein the cavity is configured to house a fluid, and an opening extends through the wall to the cavity;
- and
- an electrical power system comprising a thermoelectric generator assembly configured to couple to the wall of the first fluid containment structure, wherein a portion of the thermoelectric generator assembly is configured to be disposed within the opening, the thermoelectric generator assembly comprises a thermoelectric generator configured to be in thermal communication with the fluid within the opening and with an environment external to the first fluid containment structure, and the thermoelectric generator is configured to generate electrical power in response to a temperature differential between the fluid within the opening and the environment and is configured to provide the generated electrical power to power a first electrical device of the first fluid containment structure;
- and
- a second fluid containment structure including a second electrical device, wherein the thermoelectric generator assembly is configured to provide the generated electrical power to power the second electrical device.
An electrical power system for a resource extraction system, comprising:
- a first battery configured to be positioned at a first subsea component of the resource extraction system, wherein the first subsea component is configured to be disposed within water and to house a first fluid, the first battery is configured to be electrically coupled to a first electrical device of the first subsea component and a second electrical device of a second subsea component, and the first battery is configured to provide electrical power to the first electrical device and the second electrical device at least while electrical power from a remote electrical supply system to the first electrical device is interrupted;
- and
- a first thermoelectric generator configured to couple to the first subsea component, wherein the first thermoelectric generator is electrically coupled to the first battery, and the first thermoelectric generator is configured to generate electrical power in response to a temperature differential between the first fluid within the first subsea component and the water and to provide electrical power to the first battery.
