Since 1998, Thordon has equipped 46 ocean-going cruise vessels with our COMPAC seawater-lubricated propeller shaft bearings. None of these vessels have ever missed an itinerary or cancelled a cruise due to propeller shaft bearing or seal failure.
Compliant Operation
Extended shaft withdrawal notations are approved for all class societies with the exception of NK and KR (as they don’t have these notations). This allows the propeller shaft for open water lubricated systems to remain in place if monitoring conditions are met. Extended shaft withdrawal notations ensure technical equivalence of the COMPAC system with oil lubricated propeller shaft systems. Thordon’s COMPAC system assures ship owners/operators that there will be no environmental violations resulting from stern tube oil leakage and meets both US VIDA and Polar Code regulations guaranteeing zero risk of pollution.
Reliable Operation with Lowest OPEX
The use of an open seawater lubricated propeller shaft bearing system on cruise ships can permanently eliminate operational and accidental oil emissions from a vessel’s propulsion system. An open propeller shaft bearing system lubricated entirely by seawater is the only truly sustainable solution for ship owners that want to meet all future ship emission regulations, while significantly reducing their OPEX and ensuring reliable, safe operation for the life of the vessel.
