VT Halter Marine held a vessel naming ceremony for America’s ? rst offshore Lique? ed Natural Gas
Articulated Tug and Barge unit. The Q-LNG 4000 (barge) and the Q-Ocean Services (tug) were of? cially named in a ceremony that included U.S. Senator Roger
Wicker, U.S. Senator Cindy Hyde-Smith and U.S. Rep.
Steven Palazzo, along with Shane Guidry, CEO of Q-
LNG, and Tom Vecchiolla, President and CEO of ST
Engineering North America. Over the last four years,
Jones Act ship operators have taken steps to transi- tion their ? eets to use cleaner burning fuels, including
LNG. Designed and built by VT Halter, the barge is

The Zhoushan Islands are just off shore of east China’s Zhejiang province, and lie south of Shanghai on Hangzhou Bay. The main
Coastal Passenger Ferry for China island is home to a naval base, shipyards and a port. It is a busy island with a well-developed ferry system carrying both people and vehicles back and forth to the mainland. A ? ne new 690-passen- ger ferry, Zhoushan Islands Prosperity, has recently been added to this ? eet of vessels. It is the largest ferry to date from the Hunan
Xiangchuan Shipbuilding Industry Co., Ltd. Operated by a 20-per- son crew the sleek new twin-screw vessel will make the crossing at speeds up to 18 knots. WUT Ship Co. of Wuhan City designed the ? ne mono-hulled ferry. It is 65 x 10.6 m with a 4.3-m molded depth. Tankage includes 8000 liters for fuel, 318 liters for water and 416 liters of lube oil. This gives the vessel a continuous operating time of 12 hours. Propulsion power is provided by a pair of Cum- mins QSK60-M engines rated for 2700 hp at 1900 rpm and turning into an Advance Gearbox HCD1600 with a 4.75:1 reduction. Noise and vibration is reduced with the installation of a Vulkan/Wuxi ? ex coupling between the engine and the gear. Engine controls are by
Morse Electronic Control. The QSK60 was selected for this vessel as it meets the new Chinese emission standard GB15097. Auxil- iary power is supplied by two sets of Cummins CCEC QSN-D(M) powered Marathon MP-H-200 Kw at 50 Hz generators. A DCEC
QSB5.9 50 Kw generator set supplies harbor power.
