Abstract: The present invention relates to a system to transport petroleum fluids using a riser, capable of operating with aggressive fluids, in regions of irregular sub-sea terrain, yet using low-complexity and low-cost components and connections. The hybrid reverse transfer system, comprises: a first, top, rigid riser section, a second, bottom, flexible riser section, connected to a bottom end of the rigid riser section, and a series of support buoys connected to the rigid riser section, wherein the lower end of the bottom, flexible, riser section connects to a bottom connector on the seabed.
