7G95ME-GA10

The MAN 7G95ME‑GA10 is a low‑speed, two‑stroke main propulsion engine with seven in‑line cylinders, engineered for dual‑fuel operation using ammonia as the primary fuel and marine gas oil (MGO) as pilot; source-listed power 44800.0 kW. The supplied category identifies it as Main Engine 2-Stroke, and it is normally installed in the main engine room as the principal propulsion prime mover, normally connected directly or through the shaft line to the propeller. In that role, its primary purpose is to convert fuel energy into low-speed or marine propulsion torque for continuous vessel propulsion. Two-stroke crosshead main engines use separate crosshead and crankcase arrangements with scavenge-air and cylinder-lubrication systems, distinguishing them from trunk-piston four-stroke engines. Within the supplied list, this entry is distinguished from neighbouring variants by its model designation and the explicitly listed power; no further model-specific difference is stated in the source. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Fuel-injection or combustion faults cause cylinder imbalance, smoke, poor load response or abnormal exhaust temperature
Piston-ring, liner or cylinder-lubrication problems cause blow-by, scavenge deposits, increased wear or abnormal cylinder condition
Scavenge-air, turbocharger or cooler fouling reduces available air and causes high exhaust temperature, smoke or reduced power
Exhaust-valve or valve-actuation faults cause gas leakage, temperature imbalance or poor cylinder performance
Main, crankpin, crosshead or thrust-bearing deterioration causes abnormal temperature, oil debris, vibration or protective alarms

Service & Maintenance

Trend cylinder exhaust temperatures, scavenge condition, lubrication, bearing temperatures, pressures and load balance. Inspect piston, liner, exhaust valve, fuel equipment, scavenge spaces, turbocharging system and bearings according to the maintenance plan. Investigate metal debris, persistent cylinder imbalance or abnormal scavenge deposits promptly. Refer to the manufacturer documentation for the exact figure for clearances, pressures, wear and adjustment limits.
