Abstract
A system for serving as a connection interface between a lower landing string and an upper landing string is provided. The system includes a quick union device comprising a first quick union component that is operable to couple to the upper landing string and a second quick union component that is operable to couple to the lower landing string. The first quick union component and the second quick union component respectively include a self-aligning threading interface that provides hydraulic and electrical connections when the first and second quick union components are connected to one another. The quick union device provides real-time feedback via wireless communication transducers that measure pressure and report that the measured pressure is retained in a plurality of hydraulic lines of the second quick union component when the first and second quick union components are disconnected from one another.
