Designation decoded

5 = number of cylinders, G = Green Ultra Long Stroke, 60 = 600 mm bore, ME-C = MAN Electronically controlled Mark C, 9.6 = Mark 9.6 control generation.

Background

The G60ME-C with a 600mm bore and 2790mm stroke (S/B=4.65) is designed for panamax bulkers and medium-sized tankers. 5 cylinders is unusual at this size — typical for special applications with limited power requirements or as a backup drive.

Inspector checklist

Fuel System
  • Fuel pumps: plunger, nozzles, spray pattern for the 600mm combustion chamber
  • Pre-heating: 12-15 cSt
  • Cat fines: separator <15 ppm
  • VLSFO: stability
Running Gear and Tribology
  • 600mm liners: liner wear, BN, honing pattern
  • Piston rings: gap at 600mm — note thermal distortion
  • Crosshead: S/B=4.65, 2790mm stroke gives high side forces, LI reading critical
  • Stuffing box: drainage, extra attention needed with a long stroke
ME Control
  • HPS 300 bar: oil quality
  • FIVA Mark 9.6: timing
  • CCU: software, alarms
Turbocharger
  • Bearing clearance, vibration
  • Cleaning
  • Scavenge air pressure

Logbook reference values

Parameter Expected Deviation means
Exhaust gas temperature 320-420°C >25°C spread
Scavenge air pressure 2.0-3.5 bar TC fouling
Cylinder oil consumption 0.7-1.2 g/kWh Adjust BN
OMD <2.5% LEL Stuffing box

Common Failure Modes

Cat fine damage
Symptoms: Liner wear, debris
Causes: Separator, VLSFO
Preventive: <15 ppm.
Crosshead wear
Symptoms: LI deviation, knocking
Causes: S/B=4.65, Oil supply
Preventive: LI every 8000 op. hours.
Cold corrosion
Symptoms: Wear
Causes: BN, Part load
Preventive: Adjust BN.

Expert tips

  • 💡 5 cylinders on a G60 is unusual — check whether MAN/class torsional vibration analysis specifies particular operating restrictions (barred speed range).
  • 💡 S/B=4.65 gives the highest crosshead loading in the ME-C range — with 5 cylinders the mass balance is additionally unfavorable.
  • 💡 For this configuration: torsional damper condition is especially important.
