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.

Efficient Repairs, Delivered On Site

On site crankshaft repair eliminates the need to dismantle and ship large engine components. Instead, skilled technicians bring precision tools and advanced equipment directly to your location. Whether on a vessel at sea, an offshore platform, or a remote industrial plant, repairs are carried out in situ with the same accuracy as workshop-based service. This significantly reduces engine downtime and associated logistics costs.

Common crankshaft issues such as journal wear, scoring, taper, ovality, cracks, or bearing damage can now be rectified on site. By machining and grinding crankpins or main journals without removing the crankshaft, repairs can be completed in a fraction of the time. The portable equipment used is engineered to deliver high-precision results, often within tolerances of a few microns. Once the machining is done, final checks like hardness testing, alignment inspection, and surface finish measurement ensure the crankshaft is restored to OEM standards.

Due to the ship owner’s commitment, they were unable to hold the vessel at the Fujairah Anchor (Dubai) and wanted the repair of damaged crankpin number four of the MAN B&W 5L 16/24 to be executed while sailing the vessel.

RA Power Solutions deployed two technicians to Fujairah Anchor (Dubai) with a specially designed and compact onsite crankshaft grinding machine. In the case of the MAN B&W 5L 16/24, the standard crankpin diameter is 130 mm, and the bearing length is only 56 mm, which is considered to be very small. RA Power Solutions has designed, developed, and manufactured dedicated crankshaft grinding equipment capable of grinding crankpins without removing the crankshaft from the block.

Inspection of damaged crank pin number four was conducted, and it was observed that the minimum diameter of damaged crankpin number four was as follows.

• The minimum diameter of crankpin number four is observed as 129.39 mm.
• The maximum diameter was observed at 130.00 mm.

Thus, an ovality of 0.61 mm was observed, which is considered to be on the higher side. RA Power Solutions technicians executed the grinding of crankpin number four of MAN B&W 5L 16/24 while sailing from Fujairah Anchor (Dubai) to Galle Port, Sri Lanka. The crankpin number four was undersized by 1 mm, and the final diameter was maintained at 129.00 mm.
