5S80ME-C9.5-LGI

The MAN 5S80ME-C9.5-LGI is a low‑speed, 2‑stroke main engine with five inline cylinders that can run on methanol as primary fuel with MGO as pilot, offering high thermal efficiency and reduced emissions for small to medium vessels; source-listed power 19750.0 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.
