Common failures & inspection points
SFOC specification and boost pressure: different efficiency values depending on configuration and load range documented (177–179 g/kWh); optimization of fuel consumption
Turbocharger wear: High-efficiency design with 'low wear rate due to calibration ring' is described; durably constructed, but specific wear
Fuel quality: Required for HFO operation — contamination and sulphur content are risks; 75% of the fleet runs on HFO, therefore high management risk
Lagerschale-Überwachung: Caterpillar bietet optionales 'Crankshaft Bearing Condition Monitoring System' an — deutet auf Lagerverschleiß als Inspektionsthema hin
Cooling system corrosion at seawater inlet: Indications of typical marine corrosion in cooling systems with seawater cooling; anodes and flushing required
