French shipbuilder Chantiers de l’Atlantique has ordered Compac seawater-lubricated propeller shaft bearings from Thordon Bearings of Canada for installation to a pair of wind-assisted passenger ships operated by travel operator Accor.
When the first 220m, 22,300gt vessel is delivered in 2026, Orient Express Corinthian will be the world’s largest contemporary sail ship. The contract marks Thordon’s first reference onboard a Chantiers de l’Atlantique-built cruise ship and its first bearing installation on a wind powered ship. While three 100mtall, 1500m2 SolidSail rigs, a wind sail system develop by the French shipbuilder, will contribute significantly to propulsion, primary propulsive power will be through a conventional seawater-lubricated propeller shaft driven by an LNG-fuelled prime mover. Accor plans to run the ship on green hydrogen once the fuel is approved for ocean-going passenger ships.
Thordon’s scope of supply to the twin screw vessel includes Compac seawater-lubricated bearings machined to fit 370mm diameter propeller shafts.
Neil McDonald, Thordon Regional Manager, Northern Europe and Africa, said: “For these environmentally focused vessels, an oil-lubricated propeller shaft bearing system was out of the question, and although Chantiers de l’Atlantique has experience with our Compac seawater-lubricated bearing system across its naval vessel newbuildings, we still had to go through a lengthy and complex tendering process. I believe we won over competing water-lubricated bearing suppliers due to our patience, reputation and, ultimately, a much better performing product. Thordon’s Compac will contribute significantly to reducing the vessels’ environmental impact and maintenance costs.”
Benoît d’Alançon, Directeur General, Wenex Equipment, Thordon Bearings authorised distributor, France, said: “The Orient Express Corinthian firmly nods to both the legendary liner of the 1930s [Normandie, built at Chantiers de l’Atlantique] and that cosmopolitan icon of train travel, but modern, more environmentally sustainable technology is at the heart of this ultra-modern ship. Compac strengthens Accor’s vision of what a zero-pollution passenger ship looks like.”
Built to Bureau Veritas class and adopting its Mon-Shaft notation, Thordon’s open seawater-lubricated Compac polymer bearing is designed to promote early formation of a hydrodynamic film between the shaft and bearing. As the viscous friction acting on the rotating shaft is lower with seawater than with oil, research has shown that in addition to reduced Opex, operators also benefit from lower fuel consumption and subsequent emissions. Another benefit is that Compac negates the need for a damage-prone aft seal.
Gavin Allwright, Secretary, International Wind Ship Association (IWSA), said: “There can be no clearer sign that the passenger ship sector has accepted wind propulsion as the best way of reducing carbon emissions than Orient Express Corinthian, which is set to be the world’s largest primary wind passenger ship. We are delighted that Chantiers de l’Atlantique and Thordon Bearings – both of which are IWSA members – have been instrumental in ensuring Accor’s first luxury passenger ships operate environmentally above and below the waterline.”
There are now more than 40 commercial vessels with wind-assisted propulsion systems, with an additional 16 on order. Orient Express Corinthian, is the first of two 130 passenger/170 crew capacity ships, and is scheduled for delivery in March 2026, followed by a yet-to-be-named sister in September 2027. Accor has options on a further two ships. Wenex is set to deliver the Thordon scope for the first ship in March 2025.
