Emission Possible - The Engine Efficiency Design Index (EEDI)

The Energy Efficiency Design Index (EEDI) is conceived as a future mandatory instrument to be calculated and made as available information for new ships. EEDI represents the amount of CO2 in gram emitted when transporting one deadweight tonnage of cargo one nautical mile.

MAN Diesel & Turbo's WHR systems consists of high quality and highly efficient machinery that significantly increases overall vessel efficiency, all in close cooperation with yards, designers and owners. The systems are also an effective way to reduce the EEDI index, especially when combined with other MAN Diesel & Turbo technology such as its ultra-long-stroke G-engines or its Kappel propellers.

To this end, MAN Diesel & Turbo offers highly efficient steam and gas turbines as part of its innovative Waste Heat Recovery (WHR) system portfolio. The company is a package supplier that can integrate a WHR system -- including economisers, steam/power turbine generator and condensing unit -- into a vessel and guarantee the performance of the complete WHR system cycle. It can also deliver a package that includes the shaft generator/motor system, which provides substantial flexibility for a complete WHR cycle.

MAN Diesel & Turbo has clearly seen the possibilities offered by waste heat recovery, which generates power from energy that otherwise would be lost to the atmosphere. The WHR principle has been common knowledge for decades but was not widely exploited within the marine segment until recently.
