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

In the case of the MAN B&W 5L 16/24 crankshaft, the crankpin diameter is relatively small at 130.00 mm, with a bearing width of only 56.00 mm. To facilitate onsite crankshaft grinding of the crankpin, RA Power Solutions has designed and developed a dedicated onsite crankshaft grinding machine. This machine can be inserted through the inspection window, allowing grinding to be carried out efficiently.

RA Power Solutions deputed technicians, along with equipment, and the following actions were taken:

i) Excessive ovality of 0.97 mm was observed on crankpin No. 03 of the auxiliary engine. Line marks were also noted.
ii) All other parameters, such as hardness, MPI (for crack detection), and visual inspection, were checked and found to be within limits.

iii) Grinding of crankpin No. 03 was carried out, and the diameter was maintained at 128.50 mm (undersized by 1.50 mm).

Advantages of Engaging RA Power Solutions for Repair of Crankshaft – MAN B&W 5L 16/24

i) As a designer and manufacturer of onsite crankshaft grinding machines, we undertake modifications to the equipment, if required, to ensure the successful repair of the crankshaft.

ii) In this case, since the crankpin diameter is only 130.00 mm and the bearing width is 56.00 mm, we developed equipment capable of both grinding and polishing.

iii) We maintain a stock of bearings for popular engine makes and models, including undersized and special sizes. In this case, the required bearings were carried by our technicians, and the engine was commissioned immediately after the crankshaft repair.

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:

The hardness and MPI for crack detection was conducted and no abnormality was observed. Technicians started onsite grinding of crankpins were ground ranging from 1.0 MM undersize to 1.50 MM.

The main advantage of onsite crankshaft grinding jobs executed by RA Power Solutions is that the technicians and equipment are trained and designed to execute the job even while sailing of the vessel. There was absolutely no requirement of holding of the vessel. RA Power Solutions also supplied the undersized crankpin bearings for this engine and it was commissioned in a short notice.
