Natural gas is the fastest growing source of primary energy in the world. As a result of the current proven reserves and consumer locations, the transportation needs will considerably increase, and lead to new building programs based on 10 to 12 ships per year spread over the next decade. The need for new solutions to reduce gas transportation cost is now a centre of interest of many market players. For instance, The French company Gaz De France opted for a new propulsion concept for their new building program by fitting on board an LNG Carrier (being built in Chantiers de l'Atlantique) the first Electric Propulsion System, based on ALSTOM Power Conversion design. The ship will commence operation in late 2004.

The purpose of this paper is to compare different power production plants and propulsion systems, by considering five machinery alternatives for LNG tankers.

The reference of the comparison will be the steam turbine system presented as the current and nearly only type of propulsion for a LNG Carrier. Three of them are based on Electric Propulsion System. This paper also aims to find and to highlight all the relevant major technical differences between the alternatives, and to estimate the economic benefits, in order to promote the best propulsion system for an LNG tanker.
