摘要
FIELD: mining.;SUBSTANCE: present invention relates to a deepwater disconnectable turret system with a lazy wave rigid riser configuration. System for transporting hydrocarbons from reserves located under the sea floor. Turret is connected to a hydrocarbon production vessel floating at the sea surface. Hydrocarbons are transferred through at least one rigid catenary riser extending from the sea floor to a buoy, said system for transporting hydrocarbons comprising an upper section of the at least one substantially rigid riser, directly attached to the buoy and provided with fairings. Middle section of the rigid riser is provided with buoyancy modules so to give it a lazy wave shape. Lower section of the substantially rigid riser 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.;EFFECT: simplicity and safety of reconnection of structural elements, and maintenance thereof in a proper state.;14 cl, 3 dwg
