THE Canadian Coast Guard (CCG) has selected Thordon Bearings' COMPAC water lubricated propeller shaft bearing system for two icebreakers.
CCG, a long-standing customer of Thordon Bearings, decided to retrofit the COMPAC system to the 6,098 gross tonnes Des Groseilliers following 17 years operational experience with the Thordon solution.
The new COMPAC bearings were supplied and machined by Thordon distributor RMH Industries of Quebec, Canada, and fitted by the Chantier Davie Canada shipyard.
Des Groseilliers' 5,910-gross ton CCGS Pierre Radisson, scheduled to have its existing dovetail staves replaced with full form COMPAC bearings later in 2018.
These will again be supplied and machined by RMH Industries, along with supply of a Thordon Water Quality Package which maintains the correct seawater flow rate to the bearings and removes any abrasives in the seawater ensuring a long bearing wear life.
Thordon regional manager for the Americas Scott Groves said: "Switching to Thordon COMPAC bearings and Water Quality Packages allows an extension in bearing life, giving the Coast Guard reliable access to the asset, and ultimately savings to the Canadian taxpayer, thanks to greatly reduced maintenance costs."
A third CCG ship in the 1,200-class is also scheduled for COMPAC conversion. Commissioned in 1979 as the Franklin the vessel was declared surplus to requirements and decommissioned in 2000.
It was subsequently converted to an icebreaking Arctic scientific research vessel, renamed Amundsen, and recommissioned in 2003. The Amundsen is expected to be converted to Thordon COMPAC bearings in 2019.
