Passengers ships have specific requirements due to their two functions :

-to transport passengers

-to be floating hotels

Diesel electric propulsion has characteristics which fulfil requirements better than classical propulsion plants would.

A detailed comparison of this propulsion plant, such as proposed by ALSTHOM, and classical plants shows the advantages brought in all fields. Among such advantages : simplicity, comfort, reliability and fuel economy.

Accent is put on the type of propeller, on crash-stop performances, on global fuel consumption of the unique energy production plant which produces energy for :

-propulsion

-electric production

-heat production
