A locally-based company that manufactures bearings for large ocean ships is nominated for an international environmental award.
Thordon Bearings Inc.??s seawater-lubricated propeller shaft bearings have been shortlisted for the Ocean Environmental Protection Award.
Five companies are nominated for the award including Extreme Spill Technology of Canada, Goltens Green Technologies of Norway, International Paint and Total Lubmarine.
The winner is to named at the 2011 Sustainable Shipping Awards to be held in London, England on July 7.
There are currently more than 2,000 sea-going vessels using Thordon seawater-lubricated propeller shaft bearings.
Thordon was nominated for building a bearing system that eliminates oil from a ship??s stern tube by using seawater as the lubrication medium and Thordon non-metallic bearings in place of traditional metal bearings.
The seawater is taken from the sea, pumped through the bearing positions and then flows back into the sea. By using a Thordon bearing system, shippers can reduce millions of litres of stern tube oil discharged annually to the oceans and seas.
The risk of an emergency aft stern tube seal repair to prevent oil pollution, costing ship owners up to $250,000, is also eliminated.
Seawater lubricated propeller shaft bearings were recommended by the World Wildlife Fund and Friends of the Earth International in 2010 at the International Maritime Organization??s (IMO) Marine Environment Protection Committee meeting, which set the goal of zero pollution from ships.
Thordon Bearings designs and manufactures a range of non-polluting propeller shaft, rudder and shaftline products for the global marine market.
