Power plant officials were advised to open all the connecting rods and visually inspect the crankpins of the Wartsila 9L20. Damage to crankpin number #09 was reported. On going through the photographs of the damaged crankpin, the radius fillet on both sides of crankpin number #09 was observed to be damaged.

RA Power Solutions‘ two (2) technicians, along with an onsite crankshaft grinding machine, were deputed from our plant in New Delhi. The details of the engine and crankshaft are as follows:

Action Taken by RA Power Solutions to Repair the Crankshaft of Wartsila 9L20 in Madagascar, East Africa

i) RA Power technicians followed a standard inspection protocol, during which the damaged crankpin number 9 was subjected to a dimensional check, crack detection by MPI, hardness check, etc. A pre-inspection report was prepared.

ii) On inspection of crankpin #09, excessive ovality of 0.41 mm was observed against the specified limit of 0.03 mm. The dimensional report is pasted below. Technicians also observed bearing line marks on the crankpin.

iii) RA Power Solutions carried out the repair by undersizing crankpin #09 of the Wartsila 9L20 by 1.00 mm, as the power plant had a 1.00 mm undersized bearing available. The engine was successfully commissioned in the presence of our technicians.

iv) The onsite crankshaft grinding machine, developed and manufactured by RA Power Solutions, is of the latest design and maintains a tolerance within 0.02 mm (20 microns) after grinding. The surface finish achieved is of a very high standard—15 RA value or less—which is highly recommended for ensuring the long life of bearings and crankshafts.
