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.
