Thordon Bearings: EAL Protection in a Class of its Own
The ideal solution for the tightening regulatory noose also brings a different (and welcome) shade of ‘green’ for workboat operators.As the US Environmental Protection Agency (EPA ramps up enforcement of regulations that mandate that all vessels over 24 meters (78 feet) operating in US waters must switch over to EALs in all oil-to-sea interfaces before their next drydocking, it is an arguably good time to be in the lubricants business. At the same time, Thordon Bearings, a manufacturer of seawater lubricated bearings for the marine industry has its own thoughts on that very topic.
Oil-to-water Conversions Success for Great Lakes Bulkers
The oil-to-water lubricated tailshaft conversion Thordon Bearings carried out last year to the 26,260dwt Great Lakes Fleet-managed bulk carrier SS John G. Munson has successfully completed its first season as a diesel-powered ship.The shaft conversion of the 1952-built self-unloader formed a key part of the mammoth 12-month power conversion project completed last year by Fincantieri’s Bay Shipbuilding yard, in Sturgeon Bay, Wisconsin, U.S.The vessel’s steam propulsion plant was replaced with an energy efficient medium-speed diesel arrangement.
Biodegradable Lubricants Under Spotlight
Thordon Bearings has welcomed an industry initiative to evaluate the effect of biodegradable lubricants on sterntube bearings following a reported marked increase in sealed oil lubricated propeller shaft bearing failures. While many ship operators consider the rise in use of environmentally acceptable lubricants (EAL) a cure-all to meeting environmental regulations, particularly in waters where the US Environmental Protection Agency (EPA) has regulated the use of mineral oils, their performance as a propeller shaft bearing lubricant has come under increasing scrutiny.
Owners Urged to Verify Safety of Deck Machinery for Polar Operation
With the Polar Code now in force, Thordon Bearings has urged shipowners and managers to verify that their vessels’ deck machinery and systems can operate safely in the extreme temperatures encountered in Arctic and Antarctic seas. Scott Groves, Thordon Bearings Regional Manager – Americas, said: “Conventional bronze bearings commonly found in everything from fairleads and lifeboat davits to winches and hoists require frequent maintenance and grease lubrication to ensure machinery is operationally effective.
Thordon’s SeaThigor up for Environmental Award
SeaThigor, the forward propeller shaft seal Thordon Bearings introduced to the market last year, has been nominated in the technology category of the Green4Sea awards, which will take place in Athens this April. Officially unveiled at Hamburg’s SMM exhibition, last September, the SeaThigor forward seal has been cited as “raising the bar in dynamic and static seal design”. It incorporates an ingenious secondary seal module to provide Safe-Return-To-Port capability in the event of a face failure of the primary seal. A pneumatically activated inflatable element prevents water ingress along the shaft, allowing for the repair of the main seal whilst at sea, or for the shaft to turn at a lower speed so the vessel can safely return to port for primary seal repair or replacement.
Cutterhead Shaft Bearing as Good as New After 10 Years of Dredging
After 10 years and more than 100,000 operating hours dredging up silt, sand, rocks and stones in some of the toughest marine environments imaginable, the Thordon Composite bearing installed on the Al Mirfa’s dredge cutter head shaft has emerged unscathed. In drydock where the NMDC-owned dredger is being upgraded, Thordon Bearings’ Dubai-based distributor, Ocean Power International, expected that even the ‘unbreakable’ might need replacing after such demanding workloads, but it didn’t.
Pods Versus Water Lubricated Props
Thordon Bearings has called on the marine industry to investigate the characteristics of both conventional seawater-lubricated propeller shaft systems and podded propulsion arrangements in order to provide shipowners with a better understanding of the two very different propulsion configurations. In a recently published White Paper, the Canadian manufacturer of the COMPAC seawater-lubricated propeller shaft bearing system believes there is a great opportunity for independent comparative data so that cruise ship operators, in particular, can make more informed procurement decisions.
Thordon Bearings Launches Oil Savings Calculator
Thordon Bearings has developed a bespoke modeling tool capable of calculating the amount of operational oil prevented from leaking into the world’s oceans with each installation of a seawater-lubricated propeller shaft bearing. To be launched officially on April 22 to coincide with Earth Day 2016, the world’s largest environmental movement, now in its 46th year, the Oil Savings Calculator shows that more than 60 million liters of oil pollution has been saved to date. “In our opinion the only acceptable propeller shaft stern tube oil leakage is zero.” said Terry McGowan, President & CEO Thordon Bearings. “Thanks to those vessels that have already installed seawater-lubricated propeller shaft bearings…
Thordon’s COMPAC for US’ Largest Containerships
Thordon Bearings has signed a contract to supply COMPAC seawater-lubricated propeller shaft bearing solutions to two Jones Act containerships under construction at the Aker Philadelphia Shipyard Inc. (APSI) for Matson Navigation Company, Inc. The order represents the first large containership reference for the manufacturer and the largest commercial ship propeller shafts to be fitted with COMPAC bearings, Thordon noted. The 3600TEU Aloha Class vessels, the largest Jones Act containerships ever built…
New Class Rules Favor Seawater Lubricated Props
Classification societies are changing their monitoring rules for seawater-lubricated propeller shafts in line with the rules governing the inspection and withdrawal of oil-lubricated stern tube systems. China Classification Society (CCS), for example, announced in July that if certain condition monitoring criteria are met, shaft withdrawal for inspection may be extended to 15 years. The rule change follows recent revisions by Lloyd’s Register and Bureau Veritas which published amended SCM and MON-SHAFT rules in January 2013 and January 2014, respectively.
Thordon's Compac Ordered for 2 EcoCoasters
Thordon Bearings’ Swedish distributor, Duwel Sweden, has signed a contract with Caterpillar Propulsion for the supply and installation of Thordon COMPAC seawater lubricated propeller shaft bearing systems to the two general cargo ships Dutch shipyard Royal Bodewes is building for Finland’s Meriaura Group. Each state-of-the-art 4700 dwt VG EcoCoaster, designed by Meriaura Group together with partners Foreship and Aker Arctic Technology, will feature COMPAC bearings, a Thordon Water Quality Package and a forward shaft seal in order to exceed current and anticipated environmental regulations.
Thordon Bearings Secures AK Ferry Contract
Thordon Bearings has received an order to supply its COMPAC system to two Alaska Ferry newbuilds under construction at the Vigor Industrial shipyard in Ketchikan, Alaska. The Canada-based company, a supplier of seawater-lubricated propeller shaft bearings, will deliver the Environmentally Acceptable Lubricant (EAL)-compliant COMPAC propeller shaft bearing system for shaft diameters of 267mm (10.5”). Thordon has a strong history with Alaskan State Ferries with its seawater lubricated bearings installed on the Matanuska, Tustumena and Kennicott.

Thordon Reports Big Orders from Chinese Shipyards
Thordon Bearings has received an order for a total of 20 seawater-lubricated COMPAC Propeller Shaft Bearing Systems for Chinese shipyards, marking the Canadian company’s most significant order for commercial vessels. Thordon Bearings, a manufacturer of advanced seawater-lubricated stern tube bearing systems, will supply COMPAC and Thordon Water Quality Packages for installation to various merchant and offshore newbuilds under construction for an undisclosed Chinese shipowner.
‘Seawater is the Ultimate EAL’
Thordon Bearings Inc., a manufacturer of seawater lubricated bearings for the global marine industry, has questioned the rise of environmentally acceptable lubricants (EALs) in oil-based stern tube seals and bearings, stating the industry can use “the most environmentally safe lubricant” there is: seawater. The U.S. Environmental Protection Agency (EPA) is enforcing regulations introduced in December 2013 that stipulate that all vessels over 24 meters in length operating in U.S. waters must switch over to EALs in all oil-to-sea interfaces before their next drydocking.
