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.

Thordon Unveils New Bearing Information Portal

Thordon Bearings has unveiled a new web-based platform to provide all the information industry professionals need to know about the commercial, technical and environmental advantages of using grease-free and water-lubricated polymer bearings across a wide variety of applications.Covering all of Thordon’s target market sectors, the new website has been designed to provide shipowners, shipyards and propulsion system integrators, in particular, with the information they need to make more informed procurement decisions…

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.

Thordon Advises WOC on Operational Oil Issue

Addressing the more than 200 delegates at the World Ocean Council’s (WOC) fourth Sustainable Ocean Summit (SOS16) last week, Thordon Bearings advised representatives of international organizations, government agencies, industry and academia about the damage of oil-lubricated propeller shaft systems on the marine environment. Thordon Bearings’ Director of Marketing and Customer Service, Craig Carter, explained that the fleet of 45,000 oceangoing vessels that continue to operate…

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…

Thordon Bearings’ seawater-lubricated propeller shaft bearing system meets classification society rules for extended shaft withdrawal periods (Image: Thordon Bearings)

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.

‘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.
