An innovative and compact mooring tensioning system

Standard chain tensioners (chain jacks) are double cylinder push- or pull-style vertical linear units with an integrated primary chain stopper. They can withstand the minimum breaking load (MBL) of the installed mooring chain. 
The chain tensioner can be configured to suit the particular requirements of various floating production units and platforms (FPSO, SPAR and semi-submersibles).

Available applications

  • Mooring chain size: 4-7” (100-180mm).
  • Mooring chain pre-tension: 100-1,000MT.
  • Primary stopper capacity: 11,000-30,000kN.
  • Linear pulling speed: up to three metres per minute.
  • Push- or pull-type tensioner.
