450_249_Austal

 

Austal Ships is one of the world‘s largest builders of fast ferries. Based in Western Australia, Austal‘s modern shipyard is situated on the Jervoise Bay waterfront in Henderson, 8 km south of the port city of Fremantle.

Austal‘s purpose built facilities feature over 20,000 square metres of under cover production space with fully enclosed shipbuilding halls, allowing the simultaneous construction of two 100 metre vessels and four 40 metre vessels.

Austal Ships is acting in a very competitive market, retaining their technical advantage. As Austal supplies fast ferries and ships to leading international operators , they need to be able to service ships remotely. A high speed network due to the amount of data being monitored and controlled is required. Since the Ethernet network is used as the main communication backbone of the vital control systems and operations of the ferries and luxury yachts, all products must be certified by Germanischer Lloyd. Hirschmann™ range of Rail Family products, including the RS2-FX/FX switch and the MICE product are Germanischer Lloyd approved.
