摘要

The present invention relates to an installation comprising seabed-to-surface connections, including a so-called floating support comprising a reel (1a), and comprising: a plurality of risers (10), the upper ends of which are solidly connected to a supporting structure (3a), and a plurality of flexible pipes (4a-4b, 4a1-4a2, 4b1-4b2) extending from the reel to the upper ends (10a) of the risers, including at least two so-called first positive-buoyancy flexible pipes positioned at different heights and guiding modules (20) solidly connected to a tendon and capable of sliding along the floats (11) of the risers.
