Austal unveils its largest ever catamaran


Friday, 10 December 2010 11:40

Austal today unveiled its largest ever catamaran to date. The vessel, measuring 113 metres in length, was towed out of the shed at its shipyard in Henderson, Western Australia.

At around 20 metres longer than a standard soccer pitch and weighing around 1000 tonnes, the vessel will be able to hold up to 1,400 passengers and 357 cars when complete and travel at speeds of up to 40 knots. The vessel is the heaviest Austal has ever built weighing slightly more than the 127 metre trimaran “Benchijigua Express” delivered to Fred. Olsen, S.A. in 2005.

Due to the enormous scale of the ship, the upper deck, which has been constructed as a separate “Super Unit” has to be fitted after the vessel leaves the fabrication hall. The “Super Unit” weighs in at over 170 tonnes which is more then the total aluminium weight of two 47.5m vessels also currently under construction.

Today Austal commenced joining the two parts together using its own advanced and highly specialised aluminium welding techniques. This began in the early hours of the morning with the lifting of the “Super Unit”. The rest of the vessel was then towed from the fabrication hall and positioned beneath the “Super unit”. The delicate process of lowering the unit and aligning it with the main structure was successfully completed just a few hours after the challenging operation began.

Austal’s ability to successfully marry the two complex structures and systems is due in large part to its Advanced Ship Building processes. These include the use of a multi headed gantry welder which on this vessel has been used to weld nearly 53 kilometres of aluminium structural planking.

The ship which is bound for Denmark in mid 2011 will be utilised as a vehicle passenger ferry linking Denmark and Sweden.
