Dredger: 9-Year Wear Life on Cutterhead Shaft Bearings
While the marine industry is rife with rough working conditions, dredging operations arguably pose the toughest challenge to any class of marine equipment. Water lubricated Thordon Composite cutterhead shaft bearings have reportedly performed well for nine years on one of the largest cutter suction dredgers in the world –Dredging, Environmental and Marine Engineering N.V. (DEME)’s D’Artagnan (28,200 kW total installed power). The vessel had a major dry docking at Drydocks World-Dubai in February 2014 where the shaft was removed, and bearings and shaft inspected.
Cutterhead Shaft Bearings Last 9 Years on Dredger

Originally built in 2005, the D'Artagnanself-propelled cutter suction dredgeris involved in very heavy rock-breaking having a cutting power for operations in rock soils of 6000 kW.
