Abstract: A technique for engaging a bore connector with a receptacle on subsea equipment. The technique may include providing an operator with a visual indication of acceptable alignment between the connector and the receptacle in advance of attaining engagement. In this way, a proper and reliably sealed engagement may be achieved. Further, the bore connector and techniques for use thereof include added indication of completed sealed engagement sufficient for testing and/or operational use of the connector in supporting a fluid application directed at the equipment through the receptacle.

Abstract: A tubing hanger landing system includes a tubing hanger running tool, a locking flowline to lock the tubing hanger running tool into a tubing hanger, and a lower body shear joint comprising a recovery valve. The recovery valve includes a valve body with a functional port, an operational port, a bi-directional port, and a relief port, and a valve piston positioned within the valve body and movable between an operational position and a relief position within the valve body. The functional port enables pressure to be communicated to the valve piston to move the valve piston from the operational position to the relief position, and, in the relief position, the valve piston provides fluid communication through a relief flowpath between the bi-directional port and the relief port to release pressure from the locking flowline.

Abstract: A tubing hanger landing system includes a tubing hanger running tool, a locking flowline to lock the tubing hanger running tool into a tubing hanger, and a lower body shear joint having a recovery valve. The recovery valve includes a valve body having an operational port, a bi-directional port, a relief port, and an internal piston cavity. The piston cavity includes a radially inwardly extending stop and a valve piston movable between an operational position and a relief position relative to the radially inwardly extending stop. The valve body further includes a shear port that allows pressure communication between the exterior of the recovery valve and the valve piston, a shear ring attached and surrounding a piston collar and sized larger than the radially inwardly extending stop such that the valve piston is prevented from moving from the operational position to the relief position.

The recovery valve includes a valve body having an operational port, a bi-directional port, and a relief port and an internal piston cavity. The piston cavity includes a radially inwardly extending stop, a valve piston housed in the valve body piston cavity and partially extending through the radially inwardly extending stop and movable between an operational position and a relief position by moving relative to the radially inwardly extending stop. The valve piston includes a radially extending collar.
