The invention relates to a system (1) for transporting hydrocarbons from reserves located under the sea floor (2) to a turret (3) connected to a hydrocarbon production vessel floating at the sea surface, the hydrocarbons being transferred through at least one rigid catenary riser (4) extending from the sea floor (2) to a buoy (6), said system for transporting hydrocarbons comprising an upper section of the at least one substantially rigid riser (4) directly attached to the buoy and provided with fairings, a middle section of the rigid riser (4) is provided with buoyancy modules (8) so to give it a lazy wave shape and a lower section of the substantially rigid riser (4) is in contact with the seafloor at a distance X from the buoy vertical axis that is smaller than a distance Y between the buoy vertical axis and the mooring lines anchoring means.
