Austal’s next generation 102-metre high speed trimaran has had its unique three-engine layout successfully installed ahead of the vessel’s launch next month.

The vehicle-passenger ferry, which is being built at Austal’s Western Australian facilities and is currently available for purchase, is scheduled for completion by February 2010.

Unique to the vessel is a patented three engine layout that combines with the trimaran’s hydrodynamic hull form to deliver fuel efficiency across a range of operating conditions. Each of the three MTU 20V 8000 M71L diesel engines produce 9,100kW at less than 1,200rpm and offer the world’s highest power-to-weight ratio in their power range.

“A three-engine layout saves weight over the traditional four-engine layout, delivering improvements to fuel consumption and daily running costs,” said Dr. Tony Armstong, head of Austal Design.  “Compared to other high speed craft with the same installed power, Austal’s next generation trimaran allows greater speed, and achieves lower fuel consumption when operating at the same speeds.”

Austal’s latest trimaran ferry builds on the company’s landmark trimaran Benchijigua Express, delivered to Spanish operator Fred Olsen S.A. in 2005. Since delivery, Benchijigua Express has demonstrated the benefits of Austal’s trimaran technology in commercial operation.

Others to recognise the unique benefits of Austal’s trimaran technology include the United States Navy, for which Austal is currently building two 127-metre trimaran Littoral Combat Ships.

Austal’s new 102-metre trimaran has a maximum deadweight of 700 tonnes, a speed of up to 39 knots and the capacity for 1165 passengers and 245 cars.
