Inspector checklist
Laufzeug & Tribologie
- 800 mm, S/B 4.0 — CLU sicherheitskritisch.
- Kolbenringe: Ringbruch-Risiko.
- Crosshead: Enormous forces at S/B 4.0 and 800 mm.
Steuerung
- Massive Nockenwelle.
- Große Pumpen.
- Auslassventil.
Kraftstoff
- Cat-Fines: Absolute Priorität.
- VLSFO.
Turbolader
- Turbolader (2 Stück).
Strukturell
- NDT Pflicht.
- Zugstangen.

| Kühlwasser | 75-85 °C | Erhöhung → Kalkbildung |
Common Failure Modes
Kolbenring-Bruch
Symptoms: CLU-Sprung
Causes: 800 mm Ring-Länge + S/B 4.0
Preventive: CLU-Trend.
Kreuzkopf
Symptoms: LPI-Abfall
Causes: Enorme Kräfte
Preventive: LPI-Monitoring.
Expert tips
- 💡 6S80MC-C8: Standard VLCC-Motor. NDT an Motorblock Pflicht.
- 💡 MC-C to ME retrofit at VLCCs: evaluate economically.
