Water-Lubricated Shaft Reliability
Proven in Cruising

Ship&Offshore3-18Cover

"Water-Lubricated Shaft Reliability Proven in Cruising" article from Ship & Offshore Magazine - March 2018

Thordon has equipped 32 ocean-going cruise vessels with our COMPAC water-lubricated propeller shaft bearings, the first ones being installed in 1998.

During their years of continuous service, neither of the two cruise ships, nor any other cruise ship operating with Thordon’s water-lubricated propeller shaft bearing systems, have experienced downtime, cancellations or changes to cruise itineraries due to propeller shaft bearing or seal failure.

Find out why Thordon's COMPAC system is making waves in the industry!

  • COMPAC is proven to last!  We have references on 550+ commercial vessels that use seawater lubricated shaftlines
  • Substantially Lower Operating Cost than an Oil System
  • Zero Environmental Impact – no oil leakage headaches!
  • No Aft Seal Emergencies
  • Guaranteed Compliance
