Home' Ships and Shipping : January 2011 Contents Incat has secured a contract to build the
world's first high speed passenger Ro-Ro
ship powered by environmentally
friendly Liquified Natural Gas (LNG).
Incat Chairman Robert Clifford said,
"This is a significant step forward as the
use of natural gas powered ships must
replace ships with less environmentally
friendly engines. This first LNG powered
fast ship is expected to set the scene for
The 99-metre high-speed Ro-Pax ferry,
with capacity for over 1,000 passengers
and 153 cars, is being built at the Incat
Tasmania shipyard at Prince of Wales Bay
in Hobart for delivery in 2012 to a
customer who has requested that the
commercial arrangements and route
remain "under wraps".
Incat and Revolution Design engineers
are working closely with technical
personnel from GE in Europe and the
United States to progress this exciting
project which will be the first installation
of LNG-powered, dual fuel engines in an
Incat high-speed ferry, and the first
high-speed craft built under the HSC code
to be powered by gas turbines using LNG
as the primary fuel and marine distillate
for standby and ancillary use.
In each catamaran hull a GE Energy
LM2500 gas turbine will drive a Wärtsilä
LJX 1720 waterjet, a departure from the
usual use of two engines and two jets per
hull as in the diesel-powered Incat vessels.
The GE Energy LM2500 gas turbines
are to be modified to meet class
requirements so that either LNG or
marine distillate can be burned. The
LM2500 gas turbine is derived from the
CF6 family of wide body aircraft engines.
It powers many industrial and electrical
generation applications around the
world, using a large variety of gaseous
and liquid fuels.
Fleets of destroyer-class warships in
navies worldwide, as well as commercial
ferries and cruise ships, have turned to the
LM2500 for their marine propulsion
needs. While these applications have
utilised liquid fuel, GE has now modified
the fuel delivery system to accommodate
Liquid Natural Gas (LNG). This will allow
lower emissions and operating costs for
commercial fast ferries.
The fuel tanks for the LNG will be
installed in a compartment above the
double bottom marine distillate tanks. The
change-over between the two fuels will be
automatically controlled and seamless.
According to Incat, the design teams
at Incat and Revolution Design are
working towards a goal of making hull
069 the fastest, environmentally
cleanest, most efficient, high-speed ferry
in the world.
