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.

The major technical details of the MAN B&W 5L 16/24 engine and crankshaft are as follows:

On inspection of the crankshaft it was observed that one number crankpin developed excessive ovality of 0.59 mm and bearing line marks were observed. All other crankpin dimensions were checked and found within limits.

The one-number crankpin grinding was undertaken by RA Power Solutions technicians with a patented portable on site crankshaft grinding and polishing equipment carried by them & crankpin was undersize by 1.0 mm, maintaining the final dimensions of crankpin of MAN B&W 5L 16/24 as 129.00 mm and have saved the crankshaft of MAN B&W from rejection.

Our client, a leading shipping company based in Hong Kong, invited two companies to repair the crankshaft of MAN B&W 5L 16/24 from Singapore. The companies could not undertake the repairs as the grinding of the crankpin having a small crankpin width of only 58.50 mm required compact and special tooling which can be accommodated in a small crankpin width dimension. The removal of the crankshaft and sending it to the workshop was suggested to the client, which was not possible.

RA Power Solutions by undertaking the onsite grinding of crankpin saved the crankshaft from rejection and the vessel sailed within 9 hours of boarding a vessel by our technicians in Trincomalee port, Sri Lanka.

Availability of Undersize Bearings with RA Power Solutions:

RA Power Solutions deputed the technicians with 0.5 mm and 1.0 mm undersize bearings and after grinding 1.0 mm bearing was assembled and the engine was put back in operation.

A great saving by the ship owner with a cost-effective solution given by RA Power Solutions.
