NOVEMBER 5, 2014 — Viking Cruises has opted for seawater lubricated propeller shaft bearings for the 944 passenger, 47,800 gt cruise ship Viking Star. Built at Fincantieri's Marghera shipyard, the ship is the first of three for Viking's new Viking Ocean Cruises brand and all are equipped with Thordon Compac bearings
"We chose Thordon Compac for all our newbuildings because of the long experience of these seawater lubricated bearings which present no risk of oil pollution," says Richard Goodwin, Vice President-Engineering at Viking Ocean Cruises. "With the elimination of aft seal maintenance and no oil required, we are expecting considerable cost savings over the life of the vessels."
Designed with the environment in mind, Viking's ocean ships feature energy-efficient hybrid engines, hydro-dynamically optimized streamlined hulls and bows for maximum fuel efficiency, onboard solar panels, and equipment that minimizes exhaust pollution.The Thordon bearings have zero risk of oil discharges, as no oil is used.
The Viking Star has a Thordon Compac tapered key bearing design with a shaft size of 464mm (18.268 in).
By using seawater as a lubricant, rather than expensive biodegradable oils, Thordon Compac propeller not only eliminate the risk of oil discharges, but also eliminate the need for an aft seal. All U.S. EPA Vessel General Permit requirements are met.
