Shallow water riser support

A conduit structure ( 44 ) connects subsea oil wells to a floating structure ( 12 ) 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 ( 50 ) with a lower end ( 52 ) fixed to the seafloor and an upper end ( 54 ) lying a plurality of meters above the seafloor. A flexible pipe or hose ( 46 ) 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 ( 70 ) 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.
