摘要： In this riser installation produced using a flexible pipe (10) of the unbonded type, the pipe (10) is positioned vertically between, on the one hand, a mechanical connection (7’) at the top to a surface installation (3) and, on the other hand, a mechanical connection (6', 6", 6'") at the bottom with the sea bed (5), fluidic connections being provided at the top and at the bottom to connect the riser on the one hand to surface equipment and on the other hand to sea bed equipment (2); the bottom of the riser is at a depth of at least 1000 m where it experiences a maximum calculatable reverse end‑cap effect F and tensioning means (8) impose at the bottom of the riser a reactive tension T greater than at least 50% or even 100% of the maximum calculatable reverse end‑cap effect F developed at the bottom of the riser.
