Restoration of Marine Equipment
Professional refurbishment of crankshafts, propeller shafts, cylinder heads, engine blocks, valves, bearings, gears, and heat exchangers for marine vessels.
During long-term operations, especially for seagoing vessels running continuously under heavy loads, critical components such as crankshafts, bearings, propeller shafts, turbochargers, valves, and pistons inevitably suffer from wear, cracks, deformation, or performance degradation.
Replacing them with brand-new parts is often expensive and involves long lead times, causing costly operational downtime. Technical reconditioning is the optimal solution—saving costs while guaranteeing quality equivalent to new components.
Our Marine Equipment Reconditioning Scope
1. Crankshaft Reconditioning
- Crankpin and main journal grinding, magnetic particle crack detection.
- Built-up welding, alloy thermal spraying to restore standard dimensions.
- Shaft balancing, run-out inspection, and post-machining cooling control.
2. Shaft, Camshaft, and Tailshaft Surface Restoration
- Hard chrome plating or anti-wear metal thermal spraying.
- Surface re-machining using specialized lathes and grinding machines.
3. Turbocharger Overhaul & Repair
- Repair of turbine blades and compressor wheels.
- Replacement of bearings and oil seals, housing chemical cleaning.
- Rotor dynamic balancing and no-load testing post-assembly.
4. Valve, Cylinder Head, and Engine Block Repair
- Contact surface machining, valve seat replacement.
- Cylinder head sealing, distortion rectification via precision milling.
5. Other Precision Marine Components
- Bushings, gears, and cooling water pumps.
- Oil pump bodies and propeller shaft journals.
- Heat exchangers, flanges, and specialized bearings.
