Common failures & inspection points
SFOC-Spezifikation und Boost-Druck: Unterschiedliche Effizienzwerte je nach Ausführung und Lastbereich dokumentiert (177–179 g/kWh); Optimierung des Brennstoffv
Turbolader-Verschleiß: Hocheffiziente Ausführung mit 'low wear rate due to calibration ring' wird beschrieben; langlebig konstruiert, aber spezifische Verschlei
Brennstoff-Qualität: Bei HFO-Betrieb erforderlich — Verunreinigungen und Schwefelgehalt sind Risiken; 75% der Flotte läuft auf HFO, daher hohes Managementrisiko
Lagerschale-Überwachung: Caterpillar bietet optionales 'Crankshaft Bearing Condition Monitoring System' an — deutet auf Lagerverschleiß als Inspektionsthema hin
Kühlsystem-Korrosion bei Seewassereinlass: Hinweise auf typische marine Korrosion bei Kühlanlagen mit Seewasserkühlung; Anoden und Spülung erforderlich
