MAN Diesel & Turbo announced that its dual-fuel MAN L23/30DF engine passed its Type Approval Test (TAT) on November 2nd 2017 at CSSC Marine Power (CMP) in Zhenjiang in front of the industry’s main classification societies.
The new entry will have an output of 125 kW per cylinder at a nominal speed of 720/750 rpm.
The MAN L23/30DF’s fuel injection was simplified, and its main injector valve can be used for the injection of pilot oil.
Finn Fjeldhøj – Head of Small-Bore, Four-Stroke Engineering – MAN Diesel & Turbo, said: “The L23/30DF covers a power range of 625 – 1,200kW, which makes it particularly attractive for such ocean-going vessels as bulkers of most sizes, general cargo ships, chemical tankers, and smaller LNG-carriers, as well as ships operating in ports and near the coast. Encouragingly, shipowners around the world have already shown significant interest in the engine and we are very optimistic about its future prospects.”
The TAT conducted tests of the engine’s:
- SaCoSone alarm and safety system
- dual-fuel safety concept,
- including a test of the pilot-fuel system
- load-step performance
- and components inspection.
Furthermore, MAN L23/30DF engine was granted a certificate for compliance with IMO Tier III regulations in gas mode without any after-treatment equipment.
Carrier of dry bulk cargoes, ESL Shipping, has ordered the first six L23/30DF GenSets for two 25,000-dwt cargo carrier newbuildings, currently under construction at CSC Jinling ship yard in China.
