I've supported PT Freeport Indonesia's maintenance teams through PT CBC Indonesia since 2016, advising on crushing and conveying systems, pumps, fans, mobile equipment, aerial trams, and hydraulic and pneumatic systems.
As a Senior Technical Service Engineer, I coordinate on-site engineers, supervise part installations, conduct root-cause analysis, and train teams on mechanical-component installation and maintenance. I created sitewide bearing-regreasing and V-belt-drive design tools, and improved bearing sealing and alignment methods to increase bearing lifetime by over 300%.
Earlier, I introduced split bearings that reduced changeout time by up to 70%, delivered conveyor-pulley maintenance training that reduced support needs by 80%, and performed failure analysis on a Metso MP1000 secondary crusher.
