Dredger bearing refurbishment

摘要

Umm Al Anber, a 72m heavy duty cutter suction dredger operated by Abu Dhabi-based National Marine Dredging Company (NMDC), has completed the refurbishment of its cutterhead shaft bearings as part of an extensive refit at Dubai Maritime City. Thordon Bearings' Dubai-based distributor for the Middle East, Ocean Power International (OPI), replaced the cutterhead and intermediate line shaft bearings like-for-like with Thordon's water-lubricated composite system. The turnkey project included shaft dismantlement, laser alignment, in-situ line boring, calibration, installation and commissioning.
