Oilfield apparatus and methods of use

摘要

The invention provides a flow control valve for a subsea hydrocarbon production system and a method of use. The flow control valve comprises an inlet configured to be in fluid communication to an injection fluid conduit and an outlet configured to be in fluid communication with a subsea flow system. A flow control mechanism is disposed in a flow path between the inlet and the outlet and is arranged to adjust a flow rate through the flow path. The flow control mechanism is configured to automatically adjust the flow rate of injection fluid through the flow path according to a pressure differential between fluid pressure at the inlet and fluid pressure at the outlet. Adjustment may be self-regulating, or may be controlled by a hydraulic control circuit.

1. A hose termination unit for a fluid injection hose in a subsea hydrocarbon production system, the hose termination unit comprising:
a first coupling configured for connection to the subsea hydrocarbon production system; a second coupling configured for connection to the fluid injection hose; and a flow control valve disposed between the first and second couplings; wherein the flow control valve comprises: an inlet configured to be in fluid communication with the fluid injection hose via the second coupling; an outlet configured to be in fluid communication with a subsea flow system of the subsea hydrocarbon production system via the first coupling; and a flow control mechanism disposed in a flow path between the inlet and the outlet and arranged to regulate a flow rate through the flow path; wherein the flow control mechanism comprises a spool assembly movable in a valve bore to automatically regulate the flow rate of injection fluid through the flow path in response to a pressure differential between fluid pressure at the inlet and fluid pressure at the outlet.
