Bronze bearings in the stern roller of the Anchor Handling Tug Supply (AHTS) Vessel ES Kestrel have been replaced with grease-free SXL bearings from Thordon Bearings while the vessel remained afloat and operational.The replacement was undertaken in May 2024 by Thordon’s Dubai-based distributor Ocean Power International (OPI) for the AHTS owner Echo Cargo & Shipping of U.A.E.While typically checked during routine drydocking, the vessel’s stern roller was experiencing turning issues during operation.

Thordon Bearings won a contract to convert the rubber tailshaft bearings across an entire fleet of Panama-operating tugs, pilot vessels, and workboats to water-lubricated polymer bearings.The agreement with the unnamed operator follows the retrofitting of Thordon’s SXL tailshaft bearings to 12 of its twin-screw tugs last year during scheduled dry dockings.The remaining 32 vessels will now be converted in batches at planned maintenance intervals over the next four years.For the first batch of retrofit conversions…

It might be easy to blame EALs, but the ongoing causes of stern tube damage are varied, and possibly declining.Environmentally Acceptable lubricants (EALs) gained market traction with the introduction of US VGP regulations in 2013. Since then, DNV has observed two major trends. The first, starting in 2013 was early life damage, either during sea trials or within the first five years of operation, where aft stern tube bearings typically failed under extreme load conditions. Then from around 2018…

When a 9,280hp workboat returned to service following extensive repairs at the James Marine Paducah River Service yard in Kentucky, U.S.A., it marked the first application of Thordon’s new seal-embedded bearing to an articulating rudder, Thordon Bearings said Monday. Articulating rudders are unlike conventional rudders and can be more costly to repair when things go wrong. They are more susceptible to wear and tear, due to the higher operating pressures and abrasives, and as a result…

Thordon Bearings said Monday that its water-lubricated elastomeric polymer bearings have been  installed to well pumps aboard an undisclosed offshore oil platform operated by Abu Dhabi National Oil Company (ADNOC).Five KSB three-stage mixed flow impeller-type pumps were each retrofitted  with Thordon pump bearings - 13 SXL intermediate bearings, four Composite bearings and a single SXL throttle bearing -  replacing the  original silicon carbide bushes, the company said.Dubai-based engineering firm Ocean Power International (OPI)…

Peer-reviewed research by Thordon Bearings into the hydrodynamic lubrication efficiency of a ship’s propeller shaft bearing has found that the use of seawater-lubricated elastomeric polymer bearings reduces fuel consumption.The environmental and financial benefits of adopting a seawater-lubricated propeller shaft system are well documented, but this is the first indication that the arrangement reduces hydrodynamic resistance enough to improve fuel consumption, compared to a conventional…

Thordon Bearings’ Egyptian distributor and integrated services provider Nefertiti Marine has commissioned the water lubricated Thordon SXL propeller shaft bearings installed aboard the 24,112gt ferry Daleela.The 1991-built, 400-passenger capacity RoPax, owned by El-Etehad International and chartered to Scandro Holdings, began operations on the revived Piraeus–Limassol route in June 2022 following an extensive refit in the floating dock operated by the Suez Shipyard in Egypt.Nefertiti Marine supplied a total of 14 Thordon SXL forward…

General Atomics Electromagnetic Systems (GA-EMS) said on Friday it has been awarded a task order from Naval Surface Warfare Center, Carderock Division (NSWCCD) to conduct a manufacturing assessment of several new propulsor bearing concept designs for U.S. Navy submarines. The task order is under the Propulsor Demonstration Hardware (PDH) Indefinite Delivery, Indefinite Quantity (IDIQ) contract previously awarded to GA-EMS.“Manufacturing feasibility evaluations such as this are crucial steps in determining whether a new concept design will deliver greater performance…

A Canadian Coast Guard (CCG) icebreaker is helping to keep shipping moving on the Great Lakes throughout the winter with a set of Thordon Bearings’ propeller shaft bearings that were fitted more than 30 years ago.Canadian Coast Guard Ship (CCGS) Griffon, the oldest vessel of the CCG’s Type 1100 series, was retrofitted with a set of four Thordon XL polymer stave bearings in 1990, 20 years into her service life. Sister ships received Thordon bearings from new throughout the 1980s.

Called the Generalized Bearing Life Model (GBLM), its development will ensure that SKF customers and distributors choose the right bearing for the right application, every time.Until now, it has been difficult for engineers to predict whether a hybrid bearing will outperform a steel one in a given application, or whether the possible performance benefits that hybrid bearings enable are worth the extra investment they require. The conventional equations engineers use to calculate the rating life of a bearing do not reflect the real-world performance of hybrid designs.To rectify this issue…
