EXPLOITATION ADVANTAGES OF ELECTRIC PROPULSION

Sažetak

The exploitation advantages of diesel-electric propulsion with the last generation of podded drives using permanent magnet electrical motors towards diesel-mechanic propulsion systems, in the field of fuel consumption, utilisation of on-board space, availability, manoeuvrability and environmental impact are elaborated. Comparative analysis of fuel consumption is performed on the basis of specific consumption per shaft power, as well as consumption per mile in respect to ship’s speed. All investigated exploitation aspects show positive advantages of podded electric propulsion, not only for ship types traditionally predisposed to electrical propulsion, because of their specific operation profile, but also for almost any type of ship. Thanks to the exploitation advantages and to actual trends in fuel prices and environment protection as well as to the decrease of investment costs due to severe market competition between great electrical equipment manufacturers, further electrical propulsion expansion in the world’s fleet could certainly be expected.
