CSL’s newbuilds eliminate pollution with Thordon seawater lubricated propeller shaft bearings

CSL’s first new Trillium Class vessel, the ‘Baie St Paul’
Canadian ship owner, CSL, has removed oil from the stern tube and equipped nine of its new builds with Thordon seawater lubricated propeller shaft bearings in a bid to comply with the ongoing strict IMO regulations to reduce air pollution.

The new propeller shaft bearings use seawater rather than oil to lubricate the shafts, offering zero pollution and better efficiency. With the increasing international concern from ship owners, using seawater rather than oil and grease-free rudder bearings is the next step to improving the pollution of the world’s oceans and is a method which is fast becoming the norm in Canada, the USA and Europe.

Kevin Begley, CSL International, said: “The Trillium Class design includes many industry leading efficiency and pollution reduction features. Eliminating any possible source of pollution was given a high priority when designing these vessels.”

The new CSL Trillium Class builds include three Panamax self-unloader bulk carriers, Great Lakes self-unloader bulk carriers and two Great Lakes bulk carriers. Following the successful modification of the CSL Acaadian, CSL will install non metallic propeller shaft bearings on all new vessels built at Chengxi shipyard and Yangfan shipyard in China.
