    摘要： The present invention relates to a facility having fanned seabed-to-surface connections, said facility including a plurality of seabed-to-surface connections fanning out from a single floating substrate (1) including: 1) at least one first number (k) of first seabed-to-surface connections (3, 3-i with I = 1 to k) that each include a) a first riser, (3b, 3b-i) connected to a first underwater pipe (3e-i) resting on the seabed and tensioned in a substantially vertical manner by a first float (3c-i), and 10 b) a plunging first flexible connection pipe (3a, 3a-i) that ensures the connection between said floating substrate and said first riser; and 2) at least a second number (m) of second seabed-to-surface connections (4, 4-j with j = 1 to m) that include 2a) a second rigid pipe (4b, 4b-j) connected to a second underwater pipe (4e-j) resting on the seabed and tensioned by a second buoyancy element (4c, 4c-j), and 2b) a second flexible connection pipe (4a, 4a-j with j = 1 to m) ensuring the connection between said floating substrate (1) and said 20 second rigid pipe, each of said second flexible pipes passing through a chute (6, 6a-6b) attached to said first float.
