摘要
The present invention relates to a bottom surface connection installation of a submarine pipe resting at the bottom of the sea comprising a rigid pipe (1) rising from the bottom of the sea where it rests, to the subsurface where its upper end ( 11) is connected to a floating support (10) characterized in that said upper end (11) of the rigid pipe is connected to said floating support by: 1) a flexible pipe (2) adapted to allow the transfer of the fluid conveyed by said rigid pipe (1) towards the floating support, and2) a flexible link comprising at least one resilient damping device (4) to ensure the connection between the upper end of the riser and a point of attachment (5.41c) on said floating support, said elastic damping device (4) taking up the tension of said rigid pipe at its upper end, and allowing the variation of the distance between the upper end of the rigid pipe of and the floating support, in a controlled manner.
