New Rules for Water Lubrication
In the Feb/Mar issue of Marine Propulsion they published two articles that mentioned Thordon and the classification changes for seawater lubricated bearing systems. One focused on COMPAC and the advances in seawater-lubricated propeller shaft bearings. While the other looked at RiverTough’s performance in harsh environments. To read these articles click here.

Thordon Bearing Users Unaffected by VGP Regulations
(December 19, 2013) It’s just another day for Thordon bearing users as their decision to use seawater lubricated propeller shaft bearings has ensured compliance in their oil to sea interfaces with the U.S. Environmental Protection Agency’s (EPA) new Vessel General Permit (VGP) regulations which came into effect today.
Thordon propeller shaft bearings use the ultimate environmentally acceptable lubricant (EAL) - seawater.
Join the thousands of Thordon users unaffected by the ever-changing regulations on environmentally acceptable lubricants and make the switch to seawater lubricated bearings on board your vessel today!
And Thordon rudder bearings also eliminate the use of grease, another requirement of the VGP.
Video Highlights Conversion of a Main Guide Bearing from Oil to Water
Traditional hydro-turbines use an oil lubricated main guide bearing that can pose a risk of oil leaking down the shaft past the packing gland and contaminating the turbine’s discharge or tailwater. Many hydro-turbine operators have converted their lower main guide bearing so that it is now lubricated with the same water the turbine runs on and eliminates the oil discharges into the river. It also brings operational and maintenance advantages over the original oil system. Providing water as an alternative to oil lubrication is a long standing area of expertise for . . . to read the full article or to check out the video click here.

Thordon Bearings Sums It Up
Polar Code and the Arctic Shipping Forum North America
Last week I attended the Arctic Shipping North America Conference in St. John’s, Newfoundland, Canada. The conference focused on shipping in Canada’s arctic as well as the Polar Code which was finalised last week at MEPC67 in preparation for submission to all countries soon. At many times during the conference, the Polar Code was mentioned as bringing the world up to the same standards as Canada’s Arctic Waters Pollution Prevention Act. This is interesting, as the Canadian law states the same as the Polar Code: Any discharge into the sea of oil or oily mixtures from any ships is prohibited.
