Abstract:
A safety node for a hydrocarbon extraction facility control system, the node comprising: a hydraulic input; a hydraulic output; a directional control valve disposed between the hydraulic input and the hydraulic output; and a functional safety electronics module containing a logic solver in operable communication with the directional control valve; wherein the logic solver is configured to operate the directional control valve to permit hydraulic communication between the hydraulic input and the hydraulic output in response to the presence of a given condition and inhibit hydraulic communication between the hydraulic input and the hydraulic output in response to the absence of a given condition.

Claim (Index 10):
A method of controlling a valve in a hydrocarbon extraction facility comprising the steps of:\n providing a control system for the hydrocarbon extraction facility, the control system comprising a subsea control module having a hydraulic line; providing a safety node, said safety node comprising a hydraulic input, a hydraulic output, a directional control valve disposed between the hydraulic input and the hydraulic output, and a functional safety electronics module containing a logic solver in operable communication with the directional control valve, the hydraulic line being connected to the hydraulic input and the hydraulic output being connected to the valve; operating the directional control valve to permit hydraulic communication between the hydraulic input and the hydraulic output in response to the presence of a given condition and inhibit hydraulic communication between the hydraulic input and the hydraulic output in response to the absence of a given condition; and supplying hydraulic pressure to the hydraulic line when the directional control valve is operated to permit hydraulic communication between the hydraulic input and the hydraulic output to operate the valve in the hydrocarbon extraction facility.
