  • each of these anchor chains comprises means for its attachment to the ground, through a solid sunken in the seabed.
  • Their upper end extends to a maneuvering station which is arranged on the side of the platform, above its waterline, for their maneuver each by their own tensioner winch associated with activatable / deactivatable stopper means.

  • the chains extend vertically along the platform, up to each associated fairlead; then they extend in an inclined way up to their massive anchoring on the ground.
  • each chain is adjusted by the tensioner winch associated with it, and the upstream free end of the chain, which extends behind the tensioner winch falls by gravity into a container-tank adapted to its storage.
  • the chains are locked in position by the stopper means.
  • These stopper means can be provided just downstream of the tensioning winches and / or at the return fairleads.

'a lower weight than those of current installations. In addition, this installation has improved ergonomics of maneuvering.
