Home' Work Boat World : July 2009 Contents The Australian shipyard Austal has recently delivered two
69-metre vehicle-passenger catamaran ferries, 'Jazan' and
'Farasan', to the Kingdom of Saudi Arabia.
Each vessel is equipped with four MTU 4000 M73L (2,880kW at
2,050rpm) main engines, each driving Rolls-Royce Kamewa waterjets
through ZF 9050 NR2H non-reversing, horizontal transmissions.
The transmissions, designed and manufactured by ZF Marine in
Friedrichshafen, Germany, are based on the new 9000 series which
comprises many models, including vertical offset, down-angle and
vee-drive for fast craft application, as well as deep ratio models for
installation in work boats and even a special model with the input
shaft arranged above the output.
The parallel shaft, horizontal transmissions, ZF 9050 NR2H
are "handed" to permit the most compact propulsion
arrangement with twin engines arranged fore and aft in
each hull of the catamaran. Designed to meet Germanischer
Lloyd's rules, the transmission has a continuous power input
capacity of 1.466kW/rpm (e.g. 3,005kW at 2,050rpm) yet weighs
ZF Marine's relationship with Austal goes back many years. In
fact, ZF transmissions were fitted in the very first vessel built by
Austal -- a 30-metre dive catamaran delivered in 1989.
Since then, Austal has built 72 vessels fitted with 168 ZF
Marine transmissions, comprising catamarans, monohulls and
trimarans from 20 to 127 metres in length with operating speeds
between14 and 43 knots. The vessels were for either for
commercial, defence or private use and were delivered to
customers in 20 countries.
In addition, Austal is currently constructing / has orders for a
further 15 vessels with a total of 37 ZF Marine transmissions, one
of which will be the two hundredth ZF Marine transmission
delivered to Austal. These orders include four ZF 60000 NR2H
gearboxes to be installed in the first Joint High Speed Vessel -- a
103-metre catamaran which Austal has been contracted to design
and build for the US Department of Defence.
