Hong Kong has successfully completed its largest single liquefied natural gas (LNG) bunkering operation and marked a significant milestone with the first-ever ship-to-ship LNG refuelling alongside simultaneous cargo handling.

The operation, conducted at Kwai Tsing Container Terminals on June 5, saw partners CLPe and CNOOC Guangdong Water Transport Clean Energy Company deliver 10,000 cubic metres of LNG to the German container vessel Hanoi Express.

By integrating LNG bunkering directly with cargo loading and unloading in a streamlined process, the Hanoi Express was able to refuel within 24 hours, significantly reducing the ship's port turnaround time and operating costs.

“The whole operation is about 20 hours. Try to imagine that if the container ship has to wait or spare another 20 hours just for fuel adding or reloading, then it translates to a matter of time, a matter of resources and a matter of money,” said Ringo Ng, CLPe's managing director.

“When a ship has to park in any particular port, there will be a cost incurred and people incurred... So I think this is very important. There is very high demand from all these international liners.”

Ng said this achievement represents a major advancement for Hong Kong's capabilities as a green port and further solidifies the city's position as a leading hub for sustainable marine fuels.

Secretary for Transport and Logistics Mable Chan said the simultaneous operation will encourage the bunkering sector in the SAR to expand services for vessels using LNG and other green maritime fuels.

She added that this operation will enhance international shipping lines' confidence and convenience in choosing Hong Kong for their bunkering and cargo handling needs.
