DEFORMABLE CONNECTION DEVICE FOR UNDERWATER PIPES

摘要

The invention relates to a deformable coupling device intended for connecting together a seabed underwater pipe (14) for carrying a fluid and a rising underwater pipe (18) extending towards a sea surface (12), in order to be able to push said fluid to said sea surface (12), said coupling device having two opposing ends, while said seabed underwater pipe (14) has a downstream end (32) and said rising underwater pipe (18) has an upstream end (38), said opposing ends being intended for being coupled to the upstream and downstream ends, respectively. The device comprises a sealed sheath and at least one reinforcement wire wound in a helix around said sealed sheath such as to form a flexible pipe (48), and it includes at least one float (50) connected to said flexible pipe (48), such as to be able to shape said flexible pipe according to a bell-shaped curve in relation to said seabed (10).
