In-Situ machining returns ore carrier with damaged journal to service

Mitsubishi 6UECE85LS-II crankshaft

Goltens has the capability to perform all kinds of services related to diesel engine casualty repair and maintenance regardless of dimension or complexity. So when an ore carrier experienced a casualty to its 6UEC85LS main engine, Goltens (an authorized repair agent for UEC Diesel engines) was awarded the job to machine the heavily damaged 950 mm diameter journal and return the ship to service.

With the ship out of service, Goltens immediately mobilized the in-situ machinists and special equipment onboard the ship in a yard in Qinhuangdao in Northern China. Due to the size of the journal, amount of material to be removed and the urgency of the job, teams from two Goltens stations joined together to shorten the repair time and restore the engine to service as soon as possible.

After completing inspection of the crankshaft, it was determined that the fillet radii were damaged and needed to be machined and that crankshaft damage was significant and would require 8-10mm to be machined from the crankpin surface to restore the engine to operation. Detailed repair procedures and work scopes were drafted by Goltens and approved by the customer’s superintendent engineer.
