<p>Methods and apparatus are disclosed herein for placing a guide line or cable on an underwater well installation connection point in a case where there is already in place a connection line between the surface and the water bottom. By means of a self-carrying electric cable, a vehicle is lowered along the connection line, the vehicle being equipped with a drum on which is wound the guide line having a connector fixed to one end and held vertically on the vehicle. Near the underwater connection point, the vehicle is made to rotate around the connection cable in order to bring the connector into alignment with the connection point. The connector then is engaged with the connection point by allowing the vehicle to further descend, after which the vehicle is raised along the connection line by pulling on the self-carrying electric cable, causing the guide line to unwind from the drum, thereby bringing an end of the line to the surface.</p> |
