Pusnes fairlead chain stopper


Pusnes fairlead chain stopper is a combined swiveling fairlead and chain stopper designed in particular for passive mooring of floating production vessels. This unique design allows the chain to be locked at an underwater level constraining maximum loads to a limited area.

The chain stopper is a ratchet type that closes automatically during pull-in. The ratchet can be opened hydraulically or mechanically during chain pay-out.
The design greatly reduces relative motion between the chain link restrained in the stopper and the exit link.
 

Advantages:

  • Minimal chain wear
  • Compact design - low weight
  • Low installation and maintenance costs
  • Custom design for variable chain size/quality
  • Tension measuring in integrated chain stopper
  • Reduces topside deck weight
