Common Failures & Inspection Points
- Area: Zylinderliner-Scuffing: Lokales Verschweißen und Verschleiß zwischen Kolbenring und Linerinnenfläche verursacht durch unzureichende Schmierung oder Ölfilm-ZusamCheck: Visuelle Inspektion des Liners auf Kratzer, Mikroschweißungen und Verfärbungen; lokale Schliff-Rauheit prüfen; bei Bedarf Liner nachhonen oder austauschen
- Area: Kolbenkrone- und Ringrillen-Verschleiß: Oberflächentragen, Verschleiß und Risse in Kolbenkrone und Ringrillen erfordern DickenmessungenCheck: Dickenmessgerät (z.B. Fischer Dualscope MP0) verwenden; Vergleich mit Richtwerten aus OM; Kolbenkrone auf thermische Verfärbung, Risse und Ablagerungen prüfen
- Area: Brennstoffdruck-Anomalien und Rillenleckage: Zu hohes/zu niedriges Druck im Common-Rail-System und Brennstoff-Leckage aus EinspritzleitungenCheck: Brennstoffdruck während Betrieb prüfen (Richtwert bei R1); Brennstoffrücklauf auf Undichtheiten kontrollieren; Inspektionsleitungen an Injektoren auf Lecks überwachen
- Area: Abgastemperatur-Unregelmäßigkeiten mit erhöhter Gaskonzentration in Kolbenunterseite: Asymmetrische oder unerwartete Abgastemperaturen stromabwärts einzelner ZyCheck: Kontinuierliche Abgastemperatur-Überwachung pro Zylinder durchführen; bei Temp.-Unterschieden >30°C Zylinderkopf-Inspektionen einleiten; Gaskonzentration im Kolben prüfen
- Area: Servo-Ölsystem-Leckage und FLV/Brennstoffleitungs-Undichtheiten: Druckverlust im Servo-Hydrauliksystem und Brennstoffleck an Fuel Line ValvesCheck: Servo-Öldrück und -Durchfluss kontrollieren; alle Brennstoffleitungen und Ventilverbindungen visuell und unter Druck prüfen; Inspektionsgläser überwachen
Verifizierte Familien-Daten (Hersteller-Datenblaetter + Fachquellen, 2026-06). Teils klassen-allgemeine Inspektionspunkte — pro Eintrag Quelle.

Common Failures & Inspection Points
- Area: Severe cylinder liner wear in RTA72U (8-cyl) on ULSD at slow-steaming speeds: 30 liners replaced within 11 months; liners worn-through in 500 hours
- Area: Piston ring hydraulic locking and breakage: load-dependent cylinder oil system design flaw caused starvation in forward cylinders; excess oil prevented ring com
- Area: Carbon deposits and piston ring degradation on RTA84 forward units during heavy fuel oil operation; inconsistent lubrication quality exacerbates problem
- Area: Water ingestion in cylinders via scavenge air cooler leakage causes corrosive liner wear; vane-type water separators essential for RTA-C engines post-cooler
- Area: Chromium-ceramic piston ring (Daros) coating adhesion failure with peeling; hard contact at ring ends causes scuffing

Common Failures & Inspection Points
- Area: Fuel valve carbon deposits / fuel system blockages in low-load multi-fuel operationCheck: Inspect fuel valve nozzle spray pattern during top-overhaul; monitor differential pressure across fuel filter; verify fuel heating system temperature compliance
- Area: Piston crown thermal cracking and top-land spalling under extreme load or fuel quality variationsCheck: Measure piston crown surface condition using borescope; check for micro-cracks in top land; examine combustion bowl geometry; compare cylinder-to-cylinder pressure readings
- Area: Cylinder liner scuffing/scoring in dust-contaminated conditions or with inadequate air filtrationCheck: Perform liner diameter measurement service at each overhaul; document wear rate trending; inspect piston rings for abnormal wear patterns; check air inlet filter condition
- Area: Turbocharger surge and cavitation erosion in unsteady loading (e.g., dynamic positioning vessels)Check: Monitor turbocharger bearing temperatures during mode transitions (gas-to-diesel); inspect turbocharger for cavitation pitting on impeller; verify surge line compliance in operational envelope
- Area: Fuel gas supply system pressure regulation instability (iGPR unit hysteresis) under rapid load changesCheck: Perform fuel gas system pressure step-response test during commissioning; verify regulator response time <500ms per specification; conduct annual gas line tightness test with ultrasonic detection
