ABSTRACT:
A universal tool for simultaneous vertical connections (10) between two flow line terminals (12) and (13) to be connected, includes two vertical hydraulic connectors (14, 15) for locking to fishing mandrels (16, 17) of the bridge of connections (11). A telescopic system (18, 19) allows for the adjustment of the spacing between the connectors. A vertical movement system allows for the elevation of the second connector (15) in relation to the first connector (14) to render easy the fitting of the bridge (11) and provide compensation for vertical deviations between the flow line terminals (12, 13) to be connected. A spherical coupling system (21) set in a split housing of spherical internal sections (22, 23) allows for compensation of angular deviations. A spacing (24) and a set of spring (25) allows for compensation of horizontal deviations between those terminals (12, 13). A slot key (26) in the first connector (14) and a funnel (27) around the first fishing mandrel (16 ) allow for the orientation of the tool (10) during reentry operation in the bridge of connectors (11).
