Abstract
A conduit structure () connects subsea oil wells to a floating structure () such as a vessel, in shallow water, the conduit structure providing a low cost and reliable fluid connection during drift of the vessel. The conduit structure includes a seafloor riser support () with a lower end () fixed to the seafloor and an upper end () lying a plurality of meters above the seafloor. A flexible pipe or hose () extends in a double catenary curve from the top of the seafloor riser support, at a downward incline away from the seafloor riser support and then at an upward incline to the floating structure. A rigid pipe () can extend along a plurality of meters of the height of the riser support to minimize the required length of flexible hose and facilitate installation.
