“Fastest Ship” is Dual Fuel

MarineLog is reporting tests of a  99 meter catamaran ferry, built by Australian shipbuilder Incat Tasmania, that reportedly made 58.1 knots while fueled with Liquefied Natural Gas.  It is claimed to be “…the world’s first dual fuel high speed ferry to operate on LNG as its primary fuel, and the fastest, environmentally cleanest, most efficient, high speed ferry in the world.”

“The vessel’s high speed can be attributed to the combination of Incat wave piercing catamaran design, the use of lightweight, strong marine grade aluminum, and the power produced by the two 22MW GE LM2500 gas turbines driving Wartsila LJX 1720 SR waterjets.”

“Incat has built 25 High Speed Craft over 5,000 gross tonnes with a top speed in excess of 45 knots.”

The similarities to the Navy’s new JHSV and China’s much smaller type 022 missile boat are apparent.

Incidentally, in spite of the advanced hull form, this still takes a lot of power, two 22MW GE LM2500 turbines equates to over 59,000 shaft horsepower, so its going to use a lot of fuel.

KEY WEST, Fla. (April 24, 2013) The Military Sealift Command high-speed vessel Swift (HSV 2) with a tethered TIF-25K aerostat gets underway from Key West to conduct a series of at-sea capabilities tests to determine if the aerostat can support future Operation Martillo counter transnational organized crime operations in the U.S. 4th fleet area of responsibility.

Does any of this look familiar? (More here)

Anyone know why the original Coast Guard Aerostat program was terminated?

LEDET, This Could be Your Ride

Another interesting ship coming from Austal, the makers of the trimaran Littoral Combat Ship, Independence (sometimes referred to as the Klingon Battlecruiser). This is the Joint High Speed Vessel (JHSV). The Army and Navy are planning to buy at least ten. I would not be surprised to see them used routinely with a LEDET on board for drug enforcement.
