RA Power Solutions was advised about the failure of the two auxiliary engines crankshaft of Daihatsu 5DC-17 in the Suez Canal because of which the vessel was not able to sail. The owners of the vessel made a distress call for repair of the crankshaft. They checked from few European-based companies for grinding of the crankshaft but they couldn’t do the repairs because of the non-availability of equipment. The standard crank pin diameter is only 145 mm and the bearing width of 64 mm this needs very compact equipment to be placed on the damaged crank pin diameter to undertake grinding and polishing.
Two technicians with portable onsite crankshaft grinding machines were deputed to Cairo Egypt and boarded the vessel within 15 hrs of the first intimation call. This was possible as all our technicians have valid seamen books.
