Vessel | LAUNCH & DELIVERY Austal USA launches Hawaii Superferry


T e fourth quarter of 2008 has seen the launch of the second of two high- speed vehicle-passenger catamaran ferries from Austal USA.


A


lthough the new vessel, standing at 113m loa, is slightly over the usual size restrictions for Ship & Boat


International, it is a signifi cant addition to Austal’s passenger ferry fl eet. T e high-speed catamaran has a service


speed of 40kts and a capacity to transport 866 passengers and 282 cars. It joins sister vessel Alakai – which is 106m loa and was delivered to Hawaii Superferry in 2007 – as the largest aluminium catamaran to be built by Austal and, at the time of writing, in the USA. While the vessel shares a similar


specifi cation to Alakai, the 113m high-speed ferry is fitted with a 20m stern quarter, bi-fold ramp, for use in austere ports without shore-side loading facilities. T e hydraulically-operated aluminium ramp has a clear width of 4.5m and is designed for 42 metric tonne (1000kg) trucks.


Industry benchmark Powered by four MTU 20V 8000 M70s, the vessel continues the strong association that Austal has with MTU 8000 Series engines, which are considered the industry benchmark for high-speed diesel engines in terms of power, reliable performance and fuel economy, according to many shipbuilders. T e MTU 8000 Series diesel engines off er what is believed to be the world’s highest

power-to-weight ratio in their power range and are established as the low-risk propulsion engine option for many of the world’s leading high-speed ferry operators, with more than 160,000 combined operating hours worldwide. Delivering up to 12,200bhp (9100kW)


of continuous power, MTU’s Series 8000 has set the performance benchmarks for fuel efficiency, less than 190g/kWh, while achieving IMO MARPOL NOx emission certifi cation. On completion of


the latest Hawaii


Superferry, Austal will have installed a total of 24 MTU 8000 Series diesel engines, proven in operation on six Austal vessels over the past four years. As well as the current passenger catamaran, Austal USA has also installed two 20V 8000 Series MTU diesel engines in its 127m Littoral Combat Ship (LCS 2) Independence, which is being certifi ed in accordance with the ABS Naval Vessel Rules. T e vessel, like her sister, will be classifi ed


by Germanischer Lloyd, with the notation, ✳ 100 A5 HSC-B OC4, Highspeed Passenger/


Ro-Ro Type, MC, AUT USA Flag. The high-speed catamaran ferry is


currently being built at Austal USA’s shipyard in Mobile, Alabama, and will commence sea trials in November and December 2008. T e contractual delivery date is scheduled for March 2009. SBI


Hawaii Superferry update


Hawaii Superferry has disclosed that it will not introduce its second fast ferry to Hawaii until 2010. The company anticipates the fi nancial climate will be more conducive to start the new route. Sister vessel Alakai will continue her service in Oahu and Maui. Hawaii Superferry’s president and chief executive offi cer Tom Fargo said: “Postponing the introduction of our second ship will defer over US$10 million in start- up costs and enable us to maintain our sound fi nancial position.”
