To ensure the safe and stable supply of natural gas, my country will accelerate the construction of gas storage infrastructure

At present, in order to ensure the safe and stable supply of energy, China is accelerating the construction of natural gas production, supply, storage and sales systems and gas storage infrastructu.

Six storage tanks of the largest LNG storage base under construction in my country have completed vault hoisting

On May 17, the 6 LNG storage tanks with the largest single-tank capacity of 270,000 cubic meters in China, which were independently designed and built by China, completed the hoisting of the vault modules in the "Green Energy Port" of CNOOC Yanche.

According to reports, the vault is an important component of the LNG storage tank, equivalent to the "beam" of the LNG storage ta.

"Through precise calculation, simulation deduction and field test, the project team divides the surface of each vault module into upper, middle and lower groups and reasonably arranges 3 groups of 8 lifting poin.

According to reports, CNOOC Yancheng "Green Energy Port" is a key planning project for the construction and interconnection of the national natural gas production, supply, storage and sales syst.

The air pressure lifting operation of the largest domestic LNG storage tank was completed in Qingdao, Shandong

On May 17, the pressure lifting of the 270,000-cubic-meter large-scale liquefied natural gas storage tank at Sinopec Qingdao LNG receiving station was successful, marking the basic completion of the main structure of the outer ta.

"The first 270,000-cubic-meter full-capacity LNG storage tank in China, which was successfully completed this time, was independently developed by Sinopec, with a diameter of 106 meters and a height of 55 mete.

It is understood that the air pressure roof lifting operation is to use the principle of the closed space and the external pressure difference to slowly lift the dome structure of the storage tank from the bottom to the predetermined position on the top of the storage ta.

According to reports, the construction of the storage tank belongs to the third phase of the Qingdao LNG receiving station, which is planned to be fully completed in 202 After completion, the receiving station will have an annual handling capacity of 11-14 million tons, and an annual gas supply capacity of 15 billion cubic meters, which can continuously and stably provide clean energy for Shandong Province, the Bohai Rim and even North and East Chi.
