<p>A method for installing an underwater riser between a seabed (52) and a surface (12), and a tubular pipe suspended from a float (24): The float (24) is weighted to be able to submerge it to drive one pipe end (28) toward the seabed (52) for connecting the tubular pipe at the seabed. Unwinding the flexible pipe (20) to extend it catenary fashion between the float (24) and a surface installation (10) so as to weight the float (24) with the unwound flexible pipe (20) and cause the submersion of the float (24), whereby the other pipe end (28) is driven toward the seabed (52).</p> |
