Designation decoded

5 = Zylinderzahl, G = Green Ultra Long Stroke, 60 = Bohrung 600 mm, ME-C = MAN Electronically controlled Mark C, 9.6 = Mark 9.6 Steuerungsgeneration.

Background

Die G60ME-C mit 600mm Bohrung und 2790mm Hub (S/B=4.65) ist fuer Panamax-Bulker und mittelgrosse Tanker ausgelegt. 5 Zylinder ist unueblich bei dieser Groesse — typisch fuer Spezialanwendungen mit begrenzter Leistungsanforderung oder als Reserveantrieb.

Inspector checklist

Kraftstoffsystem
  • Kraftstoffpumpen: Plunger, Duesen, Spray-Pattern fuer 600mm-Brennraum
  • Vorwaermung: 12-15 cSt
  • Cat-Fines: Separator <15 ppm
  • VLSFO: Stabilitaet
Laufzeug und Tribologie
  • Laufbuchsen 600mm: Liner-Wear, BN, Honmuster
  • Kolbenringe: Gap bei 600mm — thermische Verformung beachten
  • Kreuzkopf: S/B=4.65, 2790mm Hub ergibt hohe Seitenkraefte, LI-Aufnahme kritisch
  • Stopfbuchse: Drainage, bei langem Hub erhoehte Aufmerksamkeit
ME-Steuerung
  • HPS 300 bar: Oelqualitaet
  • FIVA Mark 9.6: Timing
  • CCU: Software, Alarme
Turbolader
  • Lagerspiel, Vibration
  • Reinigung
  • Spuelluftdruck

Common Failure Modes

  • Cat-Fine-Schaeden

    Symptoms: Liner-Wear, Abrieb

    Causes: Separator, VLSFO

    Preventive: <15 ppm.

  • Kreuzkopf-Verschleiss

    Symptoms: LI-Abweichung, Klopfen

    Causes: S/B=4.65, Oelversorgung

    Preventive: LI alle 8000 Bh.

  • Cold Corrosion

    Symptoms: Wear

    Causes: BN, Teillast

    Preventive: BN anpassen.

Expert tips

  • 5 Zylinder bei G60 ist ungewoehnlich — pruefen ob Torsionsschwingungsanalyse von MAN/Klasse spezifische Betriebsbeschraenkungen vorsieht (Barred Speed Range).
  • S/B=4.65 ergibt hoechste Kreuzkopf-Belastung in der ME-C-Reihe — bei 5 Zylindern zusaetzlich unguenstiger Massenausgleich.
  • Bei dieser Konfiguration: Torsionsdaempfer-Zustand besonders wichtig.

Free of charge — we forward your request to qualified suppliers for MAN Energy Solutions equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
