The flexible lines are supported by respective ones of a plurality of troughs each trough lying between two pipe portions defining a first flexible line portion in a hanging double catenary configuration between the floating support and the trough, and a second flexible line portion in a single catenary configuration between the trough and the point of contact of the flexible pipe with the sea bottom. The installation has at least one support structure having a base-forming bottom portion resting on and/or anchored to, or embedded in the sea bottom and a top portion supporting at least two troughs, respectively a bottom trough and a top trough, the troughs being arranged at different heights in such a manner that the low point of the first flexible line portion passing via the bottom trough is situated below the low point of the first flexible line portion passing via the top trough.
