Abstract:
An underwater assembly includes a flow control device and an actuator coupled to the flow control device, where the actuator is configured to actuate the flow control device. The underwater assembly further includes an insulated housing surrounding the flow control device and the actuator, where the insulated housing is configured to retain heat. The underwater assembly also includes a thermal control system comprising a heat exchanger configured to control a temperature of the actuator.
Abstract:
An apparatus that includes a chemical-injection management system of a sub-sea oil and gas extraction system. The chemical-injection management system may include a flow path having an inlet and an outlet. The chemical-injection management system may also include a pump disposed in the flow path between the inlet and the outlet; wherein the pump is configured to increase the pressure of a fluid flow through the flow path.
Abstract:
A system includes a subsea chemical injection system configured to inject a chemical into a well, wherein the choke trim comprises a first cylinder comprising a first plurality of spiral flow paths, a second cylinder comprising a second plurality of spiral flow paths, wherein the first cylinder is disposed within the second cylinder, and an outer portion comprising a plurality of axial passages, wherein the second cylinder is disposed within the outer portion.
