A unit of China National Offshore Oil Company (CNOOC) has completed lifting the roof on one 270,000-cbm tank as part of an expansion project at its Ningbo LNG import facility in the Chinese province of Zhejiang.
According to a statement by CNOOC Gas & Power, the operation of lifting the roof on the fifth LNG storage tank using air pressure took place on July 30.
CNOOC Gas & Power said the roof weighs about 1,200 tons.
The LNG tank is 62.6 meters high and has nearly 100 meters in diameter. It features CNOOC’s CGTank core storage tank technology.
The state-owned energy giant is building five 270,000-cbm LNG tanks as part of the third expansion phase of the Ningbo LNG facility.
In March this year, it raised the roof on the first LNG tank and recently lifted the roofs simultaneously on two tanks.
The company said these onshore tanks have the world’s largest LNG storage capacity.
CNOOC recently completed all of the 270,000-cbm LNG storage tanks at its Binhai LNG import terminal in Jiangsu, and it is also building five 270,000-cbm tanks at the Zhuhai LNG import terminal in Guangdong.
Earlier this year, the Ningbo LNG import facility received the 600th cargo of LNG since the launch of the plant in 2012.
The LNG terminal currently has a capacity of 6 mtpa and six LNG tanks with a total capacity of 960,000 cbm.
The third expansion phase will double the capacity to 12 mtpa and is expected to be operational in 2025.
