The Augsburg testbed no. 20 hosted the test program of a nine-cylinder version of the engine that ran on fuel oil (DMA) and natural gas, including alarm and safety systems, the pilot fuel system, and the gas supply system.

The TAT also successfully tested the integration of MAN’s proprietary SaCoSone engine control system with the engine.

Lex Nijsen, head of Four-Stroke Marine, MAN Diesel & Turbo, commented: “The MAN L51/60DF, with its improved rated-output and new features such as gas-start capability, is a welcome addition to the ranks with the flexibility to act in a main or auxiliary capacity. Whether operating on fuel oil or gas, I’m certain its efficiency and high power output will be appreciated by the market.”
