In the automatic positioning of the end of an underwater flow line, particularly in deep water, on a base, the end of the flow line is lowered to a position adjacent a connecting sleeve. The end of the flow line is connected to a hauling cable extending through the sleeve and a pull is exerted on the cable to draw the end of the flow line into the sleeve. The sleeve is detachably mounted on positioning apparatus mounted on the base and pivotable relative thereto in azimuth and elevation to align with the flow line. When the end of the flow line has been received in the sleeve and locked thereto, the sleeve is positioned on the base, locked thereto and released from the apparatus which is withdrawn. |
