Austal Ltd, has just completed an 18 month study on the development of several new types of fast ferry. Their study concluded that the most promising solutions for future regulations are multi-hulled HSC code compliant ferries running at a significantly slower speeds than present fast ferries. Austal gives three examples of new designs using LNG as the main fuel. The largest example is a 127 m trimaran ferry powered by twin dual fuel GE LM2500 gas turbines. A smaller 102 m trimaran ferry uses three 4 MW Wärtsilä 9L34DF dual fuel, medium speed engines. The smallest design example is a 72 m catamaran ferry using a dual fuel diesel/LNG electric propulsion system of four 2.3 MW Bergen dual fuel engines. [More]
