A unit of China National Offshore Oil Company (CNOOC) has completed lifting the roofs on two 270,000-cbm tanks 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 roofs simultaneously using air pressure took place on June 27.
CNOOC Gas & Power said the roof has about 93 meters in diameter and weighs about 1,200 tons.
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.
The company said these onshore tanks have the world’s largest LNG storage capacity.
CNOOC just completed all of the six 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.
