Two underwater pipelines are coupled together, e.g., to join a gas or oil well line to gathering line, by (1) attaching a guide cable from a surface vessel to the free end of one line, (2) stretching the cable to ascertain the direction where the end is located, (3) pulling the second line towards this location, (4) attaching a combined handling and coupling apparatus to a predetermined point on the second line and to the cable, (5) lowering the apparatus along the stretched cable so that the free ends of the lines are in overlapping relation within the apparatus which cuts off the overlapping portins, aligns the ends, and couples them together.
