3 What is Diesel-Electric Propulsion? With diesel-electric, a prime mover drives a generator which feeds a propulsion motor through a switchboard and converters Energy Conversion Combustion Generate Rectify Invert Propel Page 3

4 What is Diesel-Electric Propulsion? Conventional System Diesel Electric System Fixed pitch or CPP propeller Auxiliary Power fed from separate net Power generation with Diesel Engine Fixed pitch propeller Auxiliary Power fed from the same net Battery Power for Backup or Full Load DIESEL GB Battery G = = DC-Link int. M Aux G DIESEL GB G M GB = Ship consumers Page 4

5 Facts Diesel-Electric Propulsion Diesel-electric propulsion systems require 8-10% more primary power than diesel-mechanical systems Losses in additional system components, i.e. generators, cables, converters, motors Diesel-electric propulsion systems have higher weight compared to diesel-mechanical systems Diesel-electric propulsion systems have higher investment cost compared to diesel-mechanical systems Diesel-electric propulsion systems will only be used, if the a.m. facts will be compensated through other advantages Page 5

6 Benefits for Diesel-Electric Propulsion Optimized overall efficiency by Using Diesel Engines in the most effective operating point Less total installed power Combination with alternative energy sources Integration of Auxilliary Systems (e.g. Elimination of Hydraulics) Lower day-to-day operating cost Fuel savings Extended maintenance intervals Compliance with the most stringent environmental regulations Reduced emission Zero emission in harbor possible Page 6
