With SMM 2012 as backdrop MAN Diesel & Turbo unveil technical advances to reduce harmful ship exhaust gas emissions & increase engine efficiency.
The highlight of the MAN trade fair booth is the large dual-fuel diesel engine, which is on show as part of a complete engine train: The propulsion system, which comprises an engine, clutch, gears and propeller, spans an impressive 14 meters.
With the 35/44DF engine MAN Diesel & Turbo has developed a highly efficient engine which, in gas mode complies with the emission standard Tier III of the International Maritime Organization that will enter into force in 2016, when the emission of nitrogen oxides in certain coastal regions must be reduced by 80 per cent compared to the Tier I standard in the year 2000.
MAN Diesel & Turbo’s trade fair presence is very much inspired by the Energy Efficiency Design Index (EEDI) set down by the International Maritime Organization. From 2013, all newly built ships must meet the specifications of the EEDI which specifies how many grams of CO2 a ship may emit per transported ton and traveled nautical mile. The EEDI is aimed at reducing fuel consumption and the resulting CO2 emissions not only through engine technology measures, but also through changes in the ship’s geometry.
MAN Diesel & Turbo is also providing information about the technical options available to comply with EEDI’s specifications, inclluding for example its G-type two-stroke engine range, which provides first-class support with its extra-long strokes for slow steaming. Further fuel efficiency is obtained in combination with MAN's range of Variable Turbine Area (VTA) turbochargers.
