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.
