Calculated metrics
Inspector checklist
- Cylinder liners: S/B 4.0 — side forces, LNG cold corrosion wear
- Piston rings: Gas conditions
- Cylinder lubrication: BN25
- Gas injection valves: 300 bar tightness
- HP compressor
- Gas detectors
- ME control
- Gas/diesel changeover
- Safety logic
- Scavenge air box: Accessible at 600 mm
- Turbocharger: Less fouling with gas
- Exhaust temperature
Logbook reference values
| Parameter | Expected | Deviation means |
|---|---|---|
| Exhaust temperature by cylinder | 310–370 °C (LNG); 350–420 °C (diesel) | Spread >15 °C → check gas/pilot |
| Gas injection pressure | 280–320 bar | Deviation → HP compressor |
| Pmax | ±2 bar | Deviation → control system |
Common Failure Modes
Expert tips
- 💡 S60ME-GI10: Scavenge air box walkable at 600 mm — significantly cleaner in LNG operation than with diesel
- 💡 HP compressor: Install vibration monitoring as an early warning system
- 💡 5 cylinders: Watch for torsional vibrations during gas/diesel changeover
