ABSTRACT:
A universal tool for simultaneous vertical connections between two flow line terminals to be connected includes two vertical hydraulic connectors (2, 3) for locking to the fishing mandrels (43, 44) of the bridge of connectors (41). A vertical compensation system provides upwards and downwards movement of the structure (6) which supports the second connector (3). A turning system of the structure is employed and a guideline orientation system includes two structural arms (4). Each arm contains a funnel in its extremity, utilized for orientation with cables and guide posts. A horizontal movement system acts through a hydraulic cylinder (17) which has a shaft (18) coupled to a telescopic arm (20). An angular compensation system utilized in the second connector (3) acts through a spherical-shaped articulation (24) which supports, through a pin (58), a supporting shaft (27) of the second connector (3). A turning system of the second connector (3) is operated through the extension and retraction of a pair of shafts of cylinders (21, 22).
