Dual-fuel engine can act as both main and auxiliary engine
Nov 02, 2017
MAN Diesel & Turbo’s MAN L51/60DF engine successfully passed its Type Approval Test (TAT), which ran from October 17th to 20th at the company’s Augsburg works in Germany, in front of the industry’s main classification societies. The nine-cylinder test engine has an output of 1,150 kW/cylinder at a nominal speed of 500/514 rpm.
The MAN L51/60DF engine can be employed both as marine main-engine and auxiliary engine. Augsburg’s testbed no. 20 hosted the test programme of a nine-cylinder version of the engine that ran on fuel oil (DMA) and natural gas.
The TAT tested the engine’s:
• alarm and safety system
• dual-fuel safety concept, including a test of its pilot-fuel system
• gas supply system.
The TAT also successfully tested the integration of MAN Diesel & Turbo’s proprietary SaCoSone engine control system with the engine.
Lex Nijsen, Head of Four-Stroke Marine, MAN Diesel & Turbo said: “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.”
