Background

The 8G60ME-C with 2790mm stroke (S/B=4.65) and 8 cylinders is a powerful configuration for large Panamax bulkers and medium-sized containerships. 8 cylinders provide approx. 33% more power than the 6-cylinder version.

Expert tips

💡 8G60: powerful Panamax configuration.
💡 S/B=4.65 with 8 cylinders: prioritise crosshead, 8 sets of spare parts.
💡 8 cylinders results in a longer engine — torsional vibrations less problematic than with 5-6 cyl.
