ABSTRACT:
A system of liason between an underwater wellhead for the production of hydrocarbons from underwater formations to a surface support. The system includes at least one flexible conduit (4) connected between the wellhead (2) and the surface support (1). Each flexible conduit is equipped at its lower end with means to limit the radius of bending or deflection and is connected vertically to the wellhead. Each conduit can be pulled or led into at least a first configuration (4a, 4'a, 4"a) in which the conduit is generally relaxed and non-tensioned, for the flow of hydrocarbons to the surface support, and at least a second configuration (4b), in which the conduit is at least partly tensioned, and sufficiently straight and upright that tools can be lowered to descend by gravity from the support surface to the well, for working of the well.
