The present disclosure relates to a tower comprising a fluid transporting pipe () and an element () for anchoring a transporting pipe () to the bottom () of the expanse of water (), which element is connected to an upstream point () of an intermediate section () of the pipe. The tower comprises a buoy () connected to a downstream point () of the intermediate section in order to keep the intermediate section () in a substantially vertical configuration. The buoy () has a height less than 1.5 times its maximum transverse direction and delimits a first through-passage (A) in which the intermediate section () is fitted. The buoy () delimits a second through-passage (B), separate from the first through-passage (A), the second through-passage (B) accepting the upper section (). The tower () comprises a coupling section () that couples the connecting upper section () to the intermediate section ().

Tower for exploiting fluid in an expanse of water and associated installation method

This method comprises connecting a downstream point () of a pipe () to a buoy () and completely submerging the buoy (). It comprises deploying in the body of water () an intermediate section () of the pipe () from the downstream point () to at least as far as an upstream point (), anchoring the upstream point (), and tensioning the intermediate section () to keep it vertical. The connecting step includes activating a traction unit () to raise the downstream point () on the buoy (). During the connecting step, the buoy () is carried in the body of water () virtually exclusively by its own floatability.

Method for installing an operating rig for a fluid in a body of water with a traction unit

This method comprises connecting a downstream point () of a pipe () to a buoy () and completely submerging the buoy (). It comprises deploying in the body of water () an intermediate section () of the pipe () from the downstream point () to at least as far as an upstream point (), anchoring the upstream point (), and tensioning the intermediate section () to keep it vertical. The height of the buoy () is less than 1.5 times its greatest transverse dimension. The method comprises moving the buoy () between a remote position and an installed position in line with an anchoring region, keeping the buoy () partly submerged on the surface () of the body of water.
