“One anti-pollution measure that has proved its worth is Carnival’s choice of Thordon COMPAC water-lubricated propeller shaft bearings which are, in my opinion, one of the best investments any operator can make. As well as eliminating pollution risks, they have proven to be so robust, it’s likely they will outlast many of the vessels.”


– Chris Joly, Principal Manager, Marine Engineering, Carnival Corp. (U.K.)

    Thordon Propeller Shaft Bearing Wear Results Mean 30 Years of Maintenance-Free Cruising

    Dec 08, 2020
    A recent inspection of the twenty-year-old water-lubricated propeller shaft bearings installed on a twin-screw cruise ship were found to be within classification society parameters and suitable for continued use for a further ten years of operation. At the shipowner’s request, Thordon Bearings – the market leader in water lubricated bearing technologies – attended the docking in Brest, France, to assess the propeller shaft liners and outboard bearings of a 2500 passenger-capacity cruise ship. The award-winning COMPAC bearings were installed in 1999.

    ForSea Ferries Opens the Door for Thordon's ThorPlas-Blue Bearings

    Nov 12, 2020
    Thordon Bearings is to retrofit its grease-free ThorPlas-Blue bearings to ForSea Ferries’ Tycho Brahe, one of the world’s most environmentally friendly ships, at its next scheduled drydocking. The decision follows the success of the bearing installation to the bow doors of Aurora, the first of two high-intensity battery-operated ferries converted by Sweden’s Oresund Drydocks and delivered in 2016. It was the first ever installation of a Thordon self-lubricating bearing to the bow doors of a ro-ro ferry.
