In-Situ crankpin grinding - Pakistan power station
Sulzer 16ZA40S crankshaft
Goltens received an enquiry from the management company of a power station in Pakistan to complete a 50,000-hour inspection of their Sulzer 16ZA40S Diesel Generator.
During the inspection, Goltens’ specialists opened the main journal bearings and crankpin bearings and found that the No.1 crankpin journal and fillet radius of generator No.3 were damaged and required repair.
To get the generator back in service as quickly as possible, the owner requested that Goltens mobilize In-Situ tools and machinists immediately. Goltens technicians quickly arrived onsite and began work immediately after.
The detailed repair procedures and respective work scopes were drafted and approved after customer advisors discussed the process with Goltens’ Senior In-Situ Supervisor.
