Common Failure Modes

  • Guide-Shoe-Verschleiß

    Symptoms: Klopfen, Temperatur

    Causes: 800 mm + Ratio 4.31

    Preventive: Spiel alle 8000 Bh alle 7

  • Cat-Fine-Schäden

    Symptoms: Liner-Verschleiß

    Causes: Cat-Fines

    Preventive: Separator maximal

  • Fundament

    Symptoms: Deflection

    Causes: Großmotor

    Preventive: Engmaschig messen

Expert tips

  • 7G80 Mark 9.6: Neueste Generation mit bester Diagnostik. EICU-Daten für proaktive Wartung nutzen.
  • Bei 7x 800 mm: Cat-Fine-Schäden kosten potentiell >560k €. Separator-Effizienz ist die wichtigste Schutzmaßnahme.
  • CII-Compliance bei großen Containerschiffen: Slow-Steaming und Routing-Optimierung haben Einfluss auf Teillast-Verhalten und TC-Matching.

Free of charge — send us your request for MAN Energy Solutions equipment. Our team checks it and replies by e-mail.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
