7S60ME-LGIM9.6
The MAN 7S60ME-LGIM9.6 is a low‑speed 7‑cylinder two‑stroke main engine delivering up to 39 550 kW at 105 rpm, capable of running on heavy fuel oil, VLSFO, MDO and methanol via high‑pressure injection.

Designation decoded
7 = number of cylinders, S = Super Long Stroke, 60 = bore 600 mm, ME = MAN Electronically controlled, LGIM = Liquid Gas Injection Methanol, 9.6 = Mark 9.6 control generation.
Background
The 7S60ME-LGIM combines 7 cylinders with the S60 platform (2400 mm stroke). Higher speed than the G60, typical for medium-sized container ships and product tankers. A more compact design than the G variant at the same bore.
Calculated metrics
Inspector checklist
- High-pressure pumps 600-700 bar: 7-cylinder delivery quantity
- Injection valves: all 7 evenly, spray pattern
- Double-wall piping: check completely
- Changeover: synchronous switching of 7 injectors
- Liners 600 mm: BN 25-40, wear rate
- Piston rings: bore polishing
- Crosshead: S/B=4.0, moderate side forces
- Stuffing box: 7 drainage lines
- HPS 300 bar: 7 FIVA valves
- Methanol maps Mark 9.6
- Timing ±0.5 degrees CA on all 7 cylinders
- Methanol detectors
- ESD: 7 injectors can be shut off
- UV/IR
- OMD: 7 cylinders
Logbook reference values
| Parameter | Expected | Deviation means |
|---|---|---|
| Exhaust temperature | 280-360 °C | >25 °C spread |
| Methanol injection pressure | 600-700 bar | Pump/filter |
| Cylinder oil consumption | 0.5-0.8 g/kWh | Dosing |
| OMD | <2.5% LEL | Leakage |
Common Failure Modes
Expert tips
- 💡 S60 vs. G60 with 7 cylinders: a shorter engine, simpler installation, but a shorter methanol injection window.
- 💡 7-cylinder S60: a compact drive for Panamax ships combining methanol operation with moderate speed.
