North Sea Trawler Receives Quick Turnaround

Written by
MAN Diesel & Turbo recently completed a noteworthy job, carrying out a turbocharger retrofit with just five weeks. The vessel in question, Faeroese trawler, ‘Sjurdaberg’, was constructed in 1985 and has successfully operated in the North Sea for over 30 years. Equipped with a 1984-built MAN 9L28/32A Alpha engine and NA34/K turbocharger, the trawler has accumulated more than 115,000 operating hours in one of the world’s major fishing grounds. Gottfried Eberle, Head of Turbocharger Retrofit – MAN Diesel & Turbo – said: “During the retrofit, we replaced the original axial MAN NA34/K unit with a modern, radial MAN TCR20 turbocharger. The main advantages of the new turbocharger are its small size and efficiency, and its short reaction time.

Thermal design of a natural gas

Written by
The fuel was tested using a special method for the engine V18 MAN 51/60DF. The study presents a detailed method on the thermal design of a natural gas - diesel dual fuel internal combustion engine. An 18 cylinder four stroke turbocharged engine is considered to operate at a maximum speed of 500 rpm for marine and power plant applications. Thermodynamic, heat transfer and fluid flow phenomena are mathematically analyzed to provide a real cycle analysis together with a complete set of calculated operation conditions, power characteristics and engine efficiencies. The method is found to provide results in close agreement to published data for the actual performance of similar engines such as V18 MAN 51/60DF.
One man, and so many anniversaries. 120 years ago, Rudolph Diesel began to work on the compression ignition engines, that would soon be named after its creator. The first prototype was completed and passed the first tests during the same year. The first diesel engine factory was established 115 years ago. The engine invented by Diesel was used in ships for the first time 110 years ago, and it has been 90 years since the first diesel-powered truck went on the road. The car MINI was first fitted with a diesel engine ten years ago. Each of these anniversaries is reason enough to commemorate the inventor, who died exactly 100 years ago.
Audi Lucas has taken up the post of Chief Digitization Officer (CDO) at MAN Diesel & Turbo, where he is tasked with maintaining and replacing "analogue" devices with digital ones in MAN Diesel turbines. Before moving to MAN, Lucas was employed at the global consultancy firm Wipro Technologies as Director. "Digitalization is not as much about technology as it is about addressing friction points in the market. Then finding new ways and business opportunities to address those points in a blindingly fast and agile way," says Lucas. MAN Diesel Chairman of the Board Uwe Lauber says: "As a creative mission, digitization goes way beyond the development of technologies," concluding that in Germany, MAN Diesel & Turbo will have an easier development of current diesel engine projects.
