Abstract
A means and method to facilitate making a flowline connection between a non-vertically disposed submerged connector means for subsea well operations. A surface vessel carrying a supply of flowline and of tension cable over a subsea well installation lowers one end of the tension cable to anchor the cable adjacent the subsea connector means and after moving away from the subsea installation, a tension control means imparts selected tension to the cable to maintain an approximate catenary curve while flowline is supported from and progressively advanced along the cable to the connector means at the subsea installation. Cable tension is controlled to provide a selected curve of the cable and flowline so that the attitude of the advancing end of the flowline is substantially aligned with the connector means at the subsea installation whereby a flowline connection with subsea pipe installations is effected without or with only minimum assistance from a diver or other subsea robot equipment.
