DF-electric concept, also dual-fuel/diesel-eletric propulsion


The propulsion plant developed by Wärtsilä for LNG carriers. It is an electric propulsion with main generators driven by dual-fuel engines that can run on either boil-off gas or MDO. The main generators feed the ship electrical system and, through a variable-speed drive system, the propulsion motors. See also LNG tanker GAZ DE FRANCE ENERGY.
