Subsurface Safety Valve Actuator
18 Jan 24
A subsurface safety valve actuation system in well tubing comprising a safety valve, piston assembly, motor, pump, spring, reservoir, first valve, and second valve configured to provide pressure in a chamber of the piston assembly that drives the safety valve to an open position, retain pressure in the chamber that retains the safety valve in the open position, release pressure in the chamber via a first hydraulic release path and/or a second hydraulic release path between the chamber and the reservoir that extends through the first valve and second valve, respectively, and the first and second hydraulic release paths being independent from each other, whereby pressure in the chamber that retains the safety valve in the open position may be released via the first or second hydraulic release path when there is a fault in the other of the first or second release path.

Multiple Load Path Actuator with Fault Detection
19 Oct 23
An actuator comprising first and second motors, first and second drive linkages, and a pivot mount configured to pivot about a pivot axis, the pivot mount connected to the first and second drive linkages at first and second mount connections offset first and second offset distances from the pivot axis, the motors and first and second drive linkages configured to provide first and second load paths between a drive housing and the pivot mount so that in a first operation state the pivot mount is in a force-balanced orientation about the pivot axis, and a proximity detector positioned to detect when the pivot mount rotates about the pivot axis above a threshold out of the force-balanced orientation, wherein a force imbalance on the pivot mount caused by a fault in one of the first or second drive linkages above a threshold is detected by the proximity detector.
