South Korean shipbuilder Hyundai Heavy Industries (HHI) has received a $650 million order to build 10 ships equipped with the most powerful diesel engines for Iran’s state-owned shipping company. The company will build 10 container ships and tankers for the ports of the Islamic Republic of Iran. Delivery will start in 2018. MAN Diesel will probably construct the diesel engines for the vessels, which reach up to 100,000 horsepower and have a very short reaction time. "The contract was signed on Friday and it is the first order from Iran in a long time," said Yonhap, South Korea’s News Agency.

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.
