Inspection

Inspector Detail

Common issues

  • Turbocharger rotor imbalance
  • Compressor wheel fouling due to dirty air filters or poor inlet air quality
  • Bearing wear or damage from inadequate lubrication or contamination
  • Seal failure due to worn or damaged components
  • Overspeed or surge damage from improper operation or control
  • Lubrication system leaks or blockages
  • Inlet or outlet ducting damage or blockages

Inspection checklist

  • Visual inspection of turbocharger casing and components for signs of wear or damage
  • Check compressor and turbine wheel condition and balance
  • Inspect bearings and seals for wear or damage
  • Verify proper lubrication system operation and filter condition
  • Check inlet and outlet ducting for blockages or damage
  • Verify control system operation and settings
  • Check for signs of overheating or excessive vibration
  • Inspect mounting and foundation for stability and security
  • Verify proper drainage and ventilation of turbocharger compartment

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

compressor_wheel5-10% reduction in diameter or 10-20% increase in vibration
turbine_wheel5-10% reduction in diameter or 10-20% increase in vibration
bearings0.1-0.5 mm clearance increase or 10-20% increase in vibration

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Compressor and turbine wheels
  • Bearings and seals
  • Lubrication system components (pumps, filters, etc.)
  • Control system components (sensors, actuators, etc.)
  • Inlet and outlet ducting components (gaskets, seals, etc.)
  • Mounting and foundation hardware (bolts, nuts, etc.)

Safety

  • High-speed rotating components (rotor, wheels)
  • Hot surfaces and components (turbine, exhaust)
  • High-pressure gas leaks or ruptures
  • Electrical shock from control system components
  • Inadequate ventilation or drainage in turbocharger compartment

Class survey

Verify turbocharger performance and efficiency, check for signs of wear or damage, and review maintenance records and schedules

Estimated lifetime: 40000-60000 hours

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
