Crack Detection Test of Wartsila VASA Engine Model 12V32LN By MPI	Hardness Test of Wartsila VASA Engine Model 12V32LN

Main observations of the crankshaft of Wartsila Vasa are :

(I) On a visual inspection of crankpin number one, having a standard diameter of 270 mm, it was found to be damaged with deep line marks, pitting, and a rough surface.

(II) The crankpin was subjected to dimensional inspection after cleaning the embedded bearing material. The following measurements were observed for Crankpin Number One:

Minimum Diameter: 269.45 mm

Maximum Diameter: 269.89 mm

Ovality Observed: 0.55 mm

(III) All other crankpins were visually inspected, and no damage or marks were observed.

(IV) As per standard procedure, Crankpin Number One was subjected to a crack detection test using the MPI process, and hardness testing was also carried out. No abnormalities were observed

(V) Crankpin Number One was undersized by on site crankshaft grinding equipment. The diameter was reduced by 1 mm to control ovality and to remove the line marks observed after the bearing seizure. The final crankpin diameter was maintained as 269.00 – 0.02 mm.
