- the main and immediate application of the invention being in the field of oil production.
- the floating support generally comprises anchoring means to remain in position despite the effects of currents, winds and waves. It also generally comprises oil storage and processing means as well as means of unloading to removal tankers, the latter being present at regular intervals to carry out the removal of the production.
- the common name of these floating supports is the Anglo-Saxon term "Floating Production Storage Offloading" (meaning "floating medium of storage, production and unloading") which is used the abbreviated term "FPSO" in the whole of the following description.
- a connecting pipe generally a flexible connecting pipe, between the upper end of said riser and a floating support on the surface, said flexible connecting pipe taking, if appropriate, by its own weight in the form of a curve in plunging chain, that is to say, descending widely below the float to then go up to this floating support.
- bottom-surface connections made by going up continuously to the subsurface of the resistant and rigid conduits consisting of tubular elements of thick steel welded or screwed together, in a chain configuration with a curvature continuously variable throughout their length in suspension, commonly called “Steel Catenary Riser” (SCRs) meaning “steel riser chain” and also commonly called “catenary type rigid pipe” or “SCR type riser”.
- Such a catenary duct may go up to the floating support surface or only to a subsurface float that tensions its upper end, which upper end is then connected to a floating support by a plunger flexible connecting pipe.
- the installation is particularly unstable and would be animated by significant movements with the swell and the currents, so that such an installation is only possible if the pipes are of flexible pipe type and not SCR type pipes that would present in the zone of the point of contact with the ground, the most constrained zone, fatigue phenomena totally incompatible with conditioning during a lifetime of 10 or even 30 years.
- the 2 bottom-surface bonds and in particular the 2 floats are spaced from each other a great distance to avoid shocks between the movements of the 2 floats and 2 flexible pipes in their respective movements under the effect of displacements of the floating support and / or swell, wind and currents.

- the two risers are also connected by means of tubular collars fixed on one of the risers and connected by rings sliding freely around the second riser, so that the two risers can follow substantially the same lateral movements while being relatively more independent in their vertical movements.
- the respective bases of the two hybrid towers when anchored by suction anchors anchored to the sea floor must be spaced a distance of at least 5 times, preferably at least 10 times , the diameter of said anchors to avoid interference in the solidity of the sea floor and ensure reliable anchoring, and
- the floats at the top of the risers are subject to displacements in a cone whose top is located at the level of the anchoring system (see fig.1), and whose angle requires to provide a distance enough between the different floats at the top of the vertical risers to avoid that they come crashing against each other.
- the float for reasons of installation installation, must have variable buoyancy characteristics so as to increase the buoyancy as the sequential hooking different riser type pipes SCR plus flexible driving, and
