On February 20, 2022, the 6 LNG storage tanks with the world's largest single-tank capacity in CNOOC's Yancheng "Green Energy Port" completed the concrete pouring of all the caps and entered the main construction stage. As the foundation of the storage tank, the cap is an important part of the structure of the storage tank. The diameter of the six caps poured this time is 100.6 meters, and the total pouring volume is 70,860 cubic meters, which is equivalent to 30 standard Olympic swimming pools. capacity.

Ren Jianxun, Deputy Manager of Expansion Department of CNOOC Yancheng "Green Energy Port" Project: In response to the low temperature environment in winter, the project team innovated technologies such as temperature control and crack prevention of mass concrete, and reasonably arranged temperature control sensors to achieve intelligent and precise temperature control. The pouring area is innovatively adjusted to a 45-degree symmetrical arrangement, which reduces the length of construction joints, effectively prevents cracks, and improves construction quality.

CNOOC Yancheng "Green Energy Port" or Jiangsu Binhai LNG Terminal Project is a key planning project for the construction and interconnection of the national natural gas production, supply, storage and sales system. A total of 10 large-scale LNG storage tanks have been built. After full operation by the end of 2023, the annual processing capacity of LNG will reach 6 million tons.Editor/Ma Xue
