Abstract: A hinge assembly suppressing periodic motions and abrasive wear that supports an axial load and integrated a releasable hinge pin with retractable latch pins. The connector arms for the hinge assembly may include bearings, smooth outer surfaces, and tight fittings to help suppress the periodic motions and abrasive wear. Adjustable mounting apertures reduce stress on the hinge system. A hinge aperture for each member enables an axial load arm, such as thrust bearings, to pass through for reducing periodic movements during pivotal operation. A lock arm can also pass through the hinge apertures. The lock arm uses a locking pin to fasten the members together. A smooth outer surface inhibits abrasive wear and creates a smooth pivoting motion. Non-circular mounting apertures may enable adjustable mounting for reducing stress on the system.

Abstract: A technique facilitates failsafe closure of a valve used in, for example, a subsea test tree. The technique utilizes a valve combined with a cutter oriented to sever well equipment passing through an interior passage of the valve. The valve is operatively coupled with an actuation system having an actuator piston which controls cutting and valve closure. The failsafe valve and the cutter are shifted to an open position by applying pressure in a control fluid chamber to shift the actuator piston. However, the actuator piston, and thus the valve and cutter, are biased toward a closed position via pressure applied in a pressure chamber and a gas precharge chamber. The combined pressure ensures adequate force for shearing of the well equipment and closure of the valve when hydraulic control pressure is lost. In some applications, additional closing force may be selectively provided to the actuator piston.
