11G90ME-C10.5

The MAN 11G90ME-C10.5 is a high‑power, low‑speed two‑stroke crosshead diesel engine delivering 67 760 kW at 84 rpm, characterised by its ultra long stroke design and fuel flexibility (HFO, VLSFO, ULSFO, MDO); source-listed power 68530.0 kW. The supplied category identifies it as Main Engine (2-Stroke Crosshead), 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.
