Egypt’s SUMED pipeline operator Arab Petroleum Pipeline Company(SUMED) has completed the tailshaft conversion to Thordon’s SXL seawater-lubricated bearing system for seven special purpose single point mooring(SPM) service boats.
The final vessel in a series of 17.5m(57.4ft) long, 1976–built service boats had its original oil-lubricated tailshaft bearings replaced with the Thordon system at Nefertiti Marine’s Yard-K, in Rosetta Nile, in December 2022. The first vessel, SUMED 10, was converted in 2019.
Referring to the first installation, Karim Abd El Karim, Engineering Manager with Nefertiti Marine, Thordon Bearings’ authorized distributor in Egypt, who has overseen the completion of all seven conversions, said: “Oil was leaking from the shafts, and the operator was looking for a longer lasting bearing solution, resistant to abrasive waterways. We proposed the SXL material as the right solution to meet all performance and environmental needs. The vessel owner agreed.”
In addition to SXL tailshaft bearings machined for shaft diameters of 95mm(3.74in), Nefertiti Marine provided classification approval drawings and advised on the installation process through to commissioning. All seven service boats received the same scope of supply.
A water-lubricated tailshaft arrangement negates the need for an aft seal, notoriously prone to failure, resulting in oil pollution, costly repairs, and downtime. Only a forward seal is required in an open system.
SUMED’s fleet of service boats assist tankers in loading shipments from the SUMED oil pipeline. The pipeline, which runs from the Ain Sokhna terminal in the Gulf of Suez to Sidi Kreir port in the Mediterranean Sea, provides an alternative to the Suez Canal for transporting oil from the Arabian Gulf region to the Mediterranean.
Thordon Bearing’s SXL and ThorPlas-Blue non-metallic bearings are ideal solutions for tugboat, dredger and other coastal workboat operators looking to easily convert their closed oil-polluting seal system to solutions more in-line with their Environmental, Sustainability and Governance goals.
An open SXL water-lubricated bearing system is also less expensive than new, white-metal bearings that operate with two oil seals; however, vessel operators looking to convert should do so before existing shaft liners are too worn, as it may be possible to use existing shaft liners and simply replace the bearings with Thordon, providing additional cost advantages.
