Recently, the first phase of Ningbo “Green Energy Port” Phase III Project, which was constructed by China National Offshore Oil Corporation (CNOOC), was completed with the civil construction of five 270,000 m3 of the world’s largest LNG storage tanks, and was transferred to the installation construction phase.
It is understood that the first five LNG storage tanks of Ningbo “Green Energy Port” Phase III project are designed by CNOOC independently, which are the largest LNG full-capacity storage tanks in the world.
The LNG storage tank dome has a large span, complex structure and curved shape, featuring a large pouring area, high pumping difficulty and complex organization and coordination interface. The project team optimized the design plan based on the geographical environment and overcame technical challenges such as tank seismic resistance, pier anti-corrosion, and ultra-low temperature insulation. Among them, 12 technological achievements filled domestic gaps.
Next, Ningbo “Green Energy Port” will proactively adopt effective technical and safety measures while simultaneously advancing the construction of the receiving station, intake, and discharge ports. It will push forward at full throttle towards achieving the annual construction targets, accelerating the development of Zhejiang Province’s first ten-million-ton LNG storage and transportation base. This initiative will actively implement the key tasks of China’s natural gas production, supply, storage, and marketing system construction, providing strong support for regional energy development and national energy security.
