    New Evidence Suggests Synthetic EALs are Behind Increase in Stern Tube Seal Failures

    Seawater-lubricated bearings pioneer Thordon Bearings has welcomed the publication of Gard’s latest research into the potential hidden costs of synthetic Environmentally Acceptable Lubricants (EALs). Far-reaching financial and environmental consequences can result when a propeller shaft seal failure occurs, with the Norway-headquartered marine insurance firm pointing to a “significant increase” in propeller shaft aft seal damage following the 2013 introduction by the US EPA of new Vessel General Permit (VGP) rules.

    Thordon's ThorPlas-Blue Bearing Wins Award for Wilson Hatch Cover Application

    Thordon Bearings’ ThorPlas-Blue grease-free bearings won the annual IBJ Environment Protection (Marine) Award 2023 during a gala dinner last night hosted by British comedian Hugh Dennis and International Bulk Journal publisher Ray Girvan. Thordon Bearings was also nominated in the Innovative Technology Award category for the same product. Designed and developed by Thordon, the polymer deck equipment bearings not only eliminate the risk of pollution from greasing systems, but also offer easy installation, and a long, maintenance-free bearing wear life.

    Thordon Bearings Grows its Presence in the European Hydropower Sector

    Two European hydropower plant operators have replaced the bearings on their Francis-type turbines with water-lubricated bearings from Canada’s Thordon Bearings after oil was leaking from their original metal bearings. In two separate contracts, Croatia-based Skoring d.o.o., Thordon’s authorized distributor for the region, supplied wicket gate bearings to the 36.8MW Hrvatska Elektroprivreda-operated plant in Rijeka, Croatia, in July. In August, they retrofitted new turbine guide bearings to turbines at the 1500kW Elektro Ljubljana-operated HPP Sava Brod plant, in Slovenia.

    ClassNK Joins Major Classification Societies by Amending Rules for Seawater-Lubricated Shafts

    Nippon Kaiji Kyokai (ClassNK) has joined the major classification societies to amend its rules relating to the inspection of seawater-lubricated propeller shaft systems. The amendment means that ships with open seawater-lubricated propeller shafts that are built to ClassNK rules are subject to the same 15-year shaft withdrawal inspection periods as oil-lubricated shafts and sterntubes, subject to monitoring criteria.

    Bearing Selection Crucial to Vertical Turbine Pump Reliability says Thordon

    Delegates at an international water industry conference learned that bearing selection plays a critical role in vertical turbine pump (VTP) performance, and that application, medium and bearing material should also be considered during pump manufacturing or refurbishment.

    Canada Continues to Buy Local with New AOPV Bearing Deal with Thordon

    Thordon Bearings has been awarded a contract to supply seawater-lubricated bearings for installation to the first of two modified versions of the Harry DeWolf-class of Arctic and Offshore Patrol Vessels (AOPV). The new ships for the Canadian Coast Guard (CCG) are on order and will be built at Irving Shipbuilding’s Halifax Shipyard. The CCG AOPV are versions of the six AOPV that Halifax Shipyard is building for the Royal Canadian Navy (RCN), all of which feature Thordon’s seawater-lubricated bearings.
