The Auxiliary engine number #02 of MAN B&W 5L 16/24 was stopped due to low air pressure, two of our technicians boarded the vessel and inspected the crankshaft. All Five (5) crankpins having a standard diameter of 130.00 MM had ovality ranging from 0.10 MM to 0.40 MM, which is considered to be on the higher side. The crankpins also had bearing line marks, rough surfaces, and localized damage, as the engine was operated in spite of the problem in the crankshaft.

The dimensional Report of crankpins is pasted below:
