A UK-based 77.1m research ship that frequently operates in ecologically sensitive marine environments has benefited from retrofitting of a grease-free water-lubricated rudder bearing and seal solution.
The 38-year-old Ocean Endeavour, operated by the UK’s Gardline, which operates a fleet of 13 multi-role survey ships, was recently fitted with Thordon’s SXL rudder bearing at UK Docks Marine Services’ Teesside drydock. The system was ordered through Bruntons Propellers, Thordon authorised UK distributor.
Ocean Endeavour, which runs a pair of Ruston 8RKCM main engines driving a single four-bladed CP propeller, was previously fitted with a bronze rudder bearing. This required replacement due to age-related wear and tear, and bronze bearing replacement can prove expensive. This kind of system requires lubricating grease, which increases the risk of pollution with grease leaking into the ocean. Thordon’s water-lubricated SXL bearing proved to be both more cost-effective and to negate the need for grease.
Neil McDonald, Thordon Regional Manager, Northern Europe and Africa, said: “The lead time and price we offer for our SXL solutions are two major benefits for ship owners and the yards carrying out refit work. A like-for-like bronze bush replacement would have taken twelve weeks for the part to be delivered and would have been very expensive. We were able to get the SXL material to the yard in a matter of days and for significantly less. With UK Docks Marine specifying SXL we contribute to the vessel and Gardline’s ESG commitment and continued environmental performance. I would also like to emphasise the fast service and delivery provided by our new distributor, Bruntons Propellers.”
Jonathan Shaw, MD Bruntons Propellers, said: “We have hit the ground running as the new UK and Ireland distributor for Thordon Bearings. As a major propeller supplier to owners and yards around the world we were approached by UK Docks Marine Services to find a new rudder bearing solution following the Ocean Endeavour’s return.”
The vessel returned to home port Great Yarmouth, after carrying out seismic exploration surveys around the Northwest Coast of Australia.
McDonald added: “This order clearly demonstrates Thordon’s ability to ship the required repair items very quickly, to avoid any delays for the ship or inconvenience for passengers and crew. The SXL bearing is also easier to machine and fit, once on site, compared to conventional bronze bearings.”
