Deputation of RA Power Solution technicians to Suez Port:

RA Power Solutions deputed two technicians, along with an onsite crankshaft grinding machine and necessary measuring instruments, to Suez Port, where they boarded the vessel. The inspection of crankshaft was conducted as per the RA Power Solutions protocol.

The following are the main observations:

(i) On the visual inspection of the crankpins, it was observed that all seven crankpins were damaged. The bearing material was embedded on a few of the crankpins. The deep bearing line marks and rough surface are also observed.

(ii) The hardness of the crankpin was taken, and no abnormality was observed.

(iii) The crack detection of all seven crankpins was undertaken by the MPI method, and no crack was observed.

(iv) On dimensional inspection of the crankpins, orality in the range of 0.10 mm to 0.26 mm was observed in the case of six crankpins. In the remaining one, a crankpin ovality of 1.40 mm was observed.

The standard details of the crankshaft are as follows:

Action taken by RA Power Solutions for the successful repair of MAN B&W crankshaft:

(i) Six numbers of crankpins were undersized by 0.5 mm.

(ii) One number of crankpins was undersized by 2.0 mm.

(iii) We strictly maintained all parameters as per the manufacturer’s requirements and the maintenance manual.

The Crankshaft of almost all engines and their respective models are repaired without removing them from the engine block. This facilitates a massive reduction in downtime for the ship owners coping with crankshaft failure and damaged journals.

The Crankshaft of Wartsila Engine 8L32 has been successfully repaired recently on board a vessel at Karwar Port Goa. The job of in-place machining of one number crankpin was a challenge as the vessel was to sail within 18 hours of boarding our technicians.

The details of the Wartsila 8L32 Engine crankshaft repaired by us is as follows

In this case, after examining the crankshaft and assessing the damage of the crankpin, the crankpin having a standard diameter of 310 mm was reduced to 308 mm. The radius fillet of the Wartsila crankshaft was also badly damaged due to the accident and was successfully repaired on board the vessel by our technicians.

The engine was commissioned in the presence of our technicians as the undersized bearing was available.
