Common issues

  • Compressor wheel fouling due to poor air filtration
  • Turbine blade erosion from high-temperature exhaust gases
  • Bearing wear and vibration caused by misalignment or imbalance
  • Oil leakage from seals and gaskets
  • Control system malfunction due to sensor or actuator failure
  • Turbocharger rotor imbalance leading to reduced efficiency and increased vibration

Inspection checklist

  • Visual inspection of compressor and turbine blades for fouling or erosion
  • Check of bearing condition and vibration levels
  • Inspection of oil system for leaks and contamination
  • Verification of control system function and sensor calibration
  • Check of turbocharger rotor balance and alignment
  • Inspection of exhaust gas inlet and outlet for blockages or damage
  • Check of compressor inlet filter condition and cleanliness
  • Verification of turbocharger performance and efficiency

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.
