| Routine visual inspection (external, oil leaks, noise) | Daily/Weekly |
|---|---|
| Compressor water washing | Daily/Weekly (as per engine load/fuel quality) |
| Turbine dry cleaning (or specialized cleaning) | Every 2,000 - 4,000 running hours |
| Bearing inspection (axial/radial clearance check) | Every 8,000 - 12,000 running hours |
| Bearing replacement (preventive) | Every 16,000 - 24,000 running hours |
| Major overhaul (rotor balancing, full inspection, replacement of wear parts) | Every 24,000 - 32,000 running hours or 3-5 years |
Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.
| Rotor axial clearance | Typically 0.15 - 0.30 mm (new), wear limit often 0.40 - 0.50 mm (refer to specific manual) |
|---|---|
| Rotor radial clearance (journal bearings) | Typically 0.20 - 0.40 mm (new), wear limit often 0.50 - 0.60 mm (refer to specific manual) |
| Turbine blade tip clearance | Visual inspection for rubbing marks; specific measurement requires specialized tools and manual. |
| Compressor blade thickness | Visual inspection for erosion; significant thinning indicates wear. |
| Sealing ring gap | Visual inspection for excessive wear or damage; replacement if gaps are visibly large or oil leakage occurs. |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Class surveyors typically verify the following: 1. Maintenance Records: Review of logbooks, service reports, and overhaul certificates for compliance with manufacturer's recommendations and class requirements. 2. Operational Performance: Witnessing satisfactory operation during sea trials or normal running, checking for unusual noise, vibration, or exhaust gas parameters. 3. External Integrity: Visual inspection for cracks, leaks (oil/gas), secure mounting, and proper insulation of hot surfaces. 4. Safety Devices: Verification of overspeed trip functionality (if applicable), proper functioning of pressure relief valves (if fitted), and alarm systems. 5. Documentation: Availability of manufacturer's manual, approved drawings, and spare parts certificates. 6. Bearing Clearances: May request to witness or review records of axial and radial bearing clearance measurements, especially during special or intermediate surveys. 7. Emergency Shutdown: Confirmation that the turbocharger can be safely shut down in an emergency.
Estimated lifetime: 60,000 - 80,000 running hours (before major component replacement like rotor shaft or complete cartridge, assuming regular maintenance and overhauls)
