Austal's second generation high speed
trimaran ferry is attracting interest in
Taiwan and China due to its high
degree of suitability for operation across
the Taiwan Strait, the Australia-based
shipbuilder has reported.
The 102-metre vehicle-passenger
ferry is currently under construction
at Austal's Australian shipyard and is
available for purchase.
Designed primarily for seakeeping and
passenger comfort, the trimaran is
extremely well suited to these routes,
which are well known for their
challenging sea conditions.
The vessel has a speed of 39 knots and
a passenger and cargo capacity of 700
tonnes maximum deadweight and will be
ready for delivery in February 2010.
The vessel is capable of making the 110
nautical mile route from Fuzhou to Taipei
in less than three hours -- or the 125
nautical mile route from Fuzhou to
Keelung in three hours and 17 minutes.
Alternatively, the ferry can make the 130
nautical mile route from Xiamen to
Taichung in three hours and 25 minutes
and the 160 nautical mile route from
Xiamen to Kaohsiung in approximately
The new 102-metre trimaran is an
evolution of Austal's 2005 trimaran ferry
The vessel utilises Austal's trimaran
technology, combining the softer roll of
monohulls with the low resistance,
stability and carrying capacity of
catamarans, to open up new markets
beyond existing fast ferry designs.
A lower roll speed means lower
accelerations experienced by passengers --
significantly reducing passenger seasickness.
The trimaran's hydrodynamic hull
form combined with its triple engine
propulsion train delivers fuel efficiency
across a range of operating conditions.
New Austal ferry piques Asian interest
Dockstavarvet has delivered the new
pilot boat 'LOS 18' to the Norwegian
Coastal Administration's Ålesund
'LOS 118' features a new configuration
that reduces its fuel consumption by
When Dockstavarvet delivered 'LOS
116' (Yard No 551), to the Norwegian
Coastal Administration in May 2008, the
boat fulfilled all requirements regarding
seakeeping, operational characteristics and
comfort. However, with a full load
displacement of 38 tonnes and oil prices
peaking in mid 2008, fuel costs became
worrying. 'LOS 116' is fitted with a quite
heavy propulsion system of two 720kW
engines with CP propellers giving a service
speed of 27 knots.
Before executing an option for four
more units of the same type the customer
ordered a review of the design aiming to
reduce fuel consumption. Docksta's design
team soon found that switching to
Volvo-Penta D16 engines at Rating 2 with
Twin Disc Quick Shift gearboxes and fixed
pitch propellers would reduce weight by
three tonnes plus another tonne on
piping and auxiliary systems.
One more tonne was shaved off from
other equipment bringing the total weight
saving to five tonnes. The preliminary
calculations indicated that the same speed
could be achieved with a reduction in fuel
consumption of 25 percent.
'LOS 118', the first boat of the new
configuration, has now been delivered to
the Ålesund Pilot Station. In trials, the full
load speed came out at 29 knots and has
allowed a de-rating of the engines to
Rating 1 while still achieving the contract
speed of 25 knots.
