Abstract (en)
[origin: WO2007023233A1] The invention relates to an installation comprising seafloor-surface connectors for at least two submarine pipelines (10a, 10b) resting on the seafloor. The inventive installation includes a first hybrid tower comprising: a) a vertical riser (1a) which is anchored (3a) to a first base and which is connected to a submarine pipeline (10a) that is resting on the seafloor, the upper end of said riser being connected to a first subsurface float (2a); and b) a first preferably-flexible connecting line (4a) which provides a link between a floating support (11) and the upper end of the riser. The inventive installation also includes a second rigid line (1b) which extends from the seafloor up to the subsurface, whereat the upper end of the rigid line is connected to a second float (2b) which is located essentially at the same depth as the first float (2a) and which is fixed to said first float at a respective second flexible connecting line (4b), thereby connecting same to one floating support (11).
