World’s Fastest & Cleanest for Buquebus in Argentina
Czech-based Chart Ferox says it’s been tapped for the LNG fuel system for a 325-foot catamaran ferry to be built by Australia’s Incat. It’s to be the first catamaran powered by twin 27,000-hp natural gas-fueled turbines, Chart Ferox says, and as such will be “the world’s fastest, environmentally cleanest, most efficient, high-speed ferry.”
Chart Ferox, which is a fully owned European subsidiary of Chart Industries, will design, build, and deliver all of the new ship’s liquefied natural gas fuel gear, including storage tank, piping and controls, and the bunkering equipment needed to fuel the ship.
Chart Ferox for LNG Bunkering Too
The ferry is destined for service in Latin America, with operator Buquebus making a regular Buenos Aires to Montevideo run, a distance of about 125 miles.
The onboard LNG storage tanks are double-walled stainless steel, with proprietary multilayer composite vacuum insulation to maximize fuel capacity – two tanks will each hold nearly 10,600 gallons, states a fact sheet for Incat hull 069. Gas is delivered to the turbine at a precise pressure and flow, Chart Ferox says, and “a secondary heat exchanger utilizes waste heat from the turbine exhaust to vaporize the LNG, changing its state to gas.”
The new boat for Buquebus will have twin GE Energy LM2500 turbine engines rated at 22 megawatts each, and twin Wärtsilä LJX 1720 waterjets, Incat says. Top speed will be 47 knots, or nearly 55 miles per hour. It will be able to carry 1,024 passengers and crew, and 155 cars.
The Chart bunkering system is designed to load two cryogenic LNG trailers simultaneously in less than one hour, “creating a virtual LNG pipeline to the ferry,” Chart Ferox says.
“With the cost difference between natural gas and traditional fuels increasing, Chart plays an important role is establishing the infrastructure to allow the transition [to LNG] to take place,” states the ferry announcement.
Tightening emission regulations “is a positive,” notes shipbuilder Incat, which launched its first high-speed catamaran September 1977 and today offers 98-, 112- and 130-meter “Wave Piercers.”
“Our design and engineering team have long been focused on maximizing efficiency and fuel economy, and will continue to lead the way,” Incat says.
