We recently completed a successful onsite repair of a BERGEN B32:40L8P engine crankshaft onboard a vessel in Jamaica.

The details of the job are as follows:

Onsite Inspection of Crankshaft – BERGEN B32:40L8P

• Two of our experienced technicians, along with our portable onsite crankshaft grinding equipment, traveled from New Delhi, India, to Jamaica.
• Our equipment is lightweight, compact, and portable, allowing it to be transported as accompanied baggage, which eliminates delays associated with cargo shipment and customs clearance.
• Upon boarding, the vessel was found fully loaded with containers, yet our team immediately initiated the crankshaft inspection.
• It was observed that Crankpin No. 5 had suffered severe damage due to a bearing failure.
• The crankpin was thoroughly cleaned, and embedded bearing material was carefully removed.
• Dimensional checks revealed:
  • Minimum Diameter: 269.75 mm
  • Maximum Diameter: 270.00 mm
  • Ovality: 0.25 mm
  • Deep scoring marks were also noted due to the bearing failure.
• A Magnetic Particle Inspection (MPI) using a high-intensity Magnaflux torch was conducted to check for cracks. No cracks or abnormalities were detected.
• Hardness testing was performed, and confirmed that values remained within permissible limits.

Onsite Grinding of BERGEN Crankpin

• The crankpin was calibrated and ground in multiple stages, with ovality strictly controlled during the process.
• Due to deep scoring, the crankpin had to be ground to an undersize of 2 mm.
• The final dimension achieved was 268.00 mm – 0.02 mm, ensuring precision and compliance with engine requirements.

Engine Commissioning

• The vessel had a 2 mm undersize bearing in stock, which was installed immediately after grinding.
• A trial run of the engine was conducted in the presence of our technicians, and performance was found to be fully satisfactory.

The vessel was boarded by our technicians in Pasir Gudang. Following are the main details of the engine:

Inspection of Crankshaft:

1. All the crankpins were inspected dimensionally, and line marks and ovality were observed on all the crankpins. The standard diameter of crankpin was 130.00 MM.
2. All other parameters, like hardness, and crack detection by MPI, were found within limits.
3. On visual inspection of the radius fillet of two (2) crankpins was found damaged.

Inspection of Engine Block

1. The Engine Block window seating area of Unit number #04 (Port Side) was found badly damaged.
2. The Cam Case was also found broken.

Few Photographs of the damaged Cam Case are given below:

i. Considering the damage, all six (6) crankpins diameter was reduced from 130.00 Mm to 129.50 MM, maintaining the tolerance of 0.02 MM.

A copy of the report indicating the final dimensions is pasted below:

ii. The broken engine block was repaired by Metal Stitching Process. The new pieces of casting were metal stitched as shown in the photographs.
