Naval Crankshaft Overhaul and Maintenance

The crankshaft is one of the most critical components of a marine engine, as it converts the reciprocating motion of the pistons into rotational energy, driving the propulsion system. Given its central role in engine operation, the crankshaft is subjected to extreme mechanical stresses, high temperatures, and significant loads throughout its service life. Regular inspection, maintenance, and timely replacement are essential to ensure optimal engine performance, reliability, and longevity.

Our naval crankshaft overhaul and maintenance services include complete crankshaft maintenance, covering every phase from detailed inspection to full refurbishment and testing. Specifically, we handle:

• Inspection: A thorough examination using advanced diagnostic tools to detect cracks, wear, misalignment, or any other structural anomalies that could compromise performance.

• Overhaul: Precision machining, straightening, grinding, and polishing to restore the crankshaft to its original specifications. If necessary, we also perform journal repairs and reconditioning.

• Final Assembly: Reinstallation of the crankshaft with strict adherence to manufacturer specifications, including proper alignment, torque application, and bearing adjustments.

• Testing: Rigorous functional and performance tests to verify the crankshaft’s integrity and ensure seamless operation within the engine system.

Whether dealing with a large main engine crankshaft or a generator crankshaft, we provide tailored solutions that meet the highest industry standards. Our expertise allows us to restore or replace crankshafts with precision, minimizing downtime and maximizing the efficiency of your vessel’s propulsion and power generation systems.
