On the shore of the South China Sea, two giant storage tanks stand on Xiaohu Island. These are the two storage tanks of the Guangzhou LNG (Liquefied Natural Gas) Emergency Peak shaving Gas Source Project Phase I, with a height of approximately 50 meters and a diameter of over 80 meters, and a single tank capacity of up to 160000 cubic meters. The reporter learned that the first phase of the Guangzhou LNG emergency peak shaving gas source project has been basically completed, and once completed, it will have a LNG storage capacity of 320000 cubic meters, which can meet the emergency support needs of Guangzhou for 10 days; The second phase project is currently under planning, and once the entire station is fully completed, there will be four 160000 cubic meters of LNG storage tanks. The first phase of the project has a storage capacity that meets the city's 10 day emergency supply. According to the introduction, the Guangzhou LNG emergency peak shaving gas source station is implemented by Guangzhou Gas Group Co., Ltd., a subsidiary of Guangzhou Development Group. It is a key construction project in the energy planning of Guangdong Province and Guangzhou City during the 13th and 14th Five Year Plans, as well as a key project in the supply side structural reform at the provincial and municipal levels to fill the gaps. It is also a key construction project in the battle map of Guangzhou City's siege and stronghold. The gas source station is divided into two phases of construction. The first phase of the project includes two sub projects: the gas storage project and the supporting dock project. It has been basically completed and is currently preparing for trial production, "said the relevant person in charge of Guangzhou Gas Group. Specifically, the design scale of Phase I project is 1 million tons/year turnover, mainly including two 160000 cubic meters of LNG storage tanks, three booster gasification production lines, and relevant supporting equipment and facilities in the factory area. A dedicated unloading dock for LNG ships with a reliable berthing capacity of 30000 to 147000 cubic meters will be constructed for the supporting dock project. The hydraulic structure will be constructed according to the scale of LNG ships with a berthing capacity of 180000 cubic meters. The first phase of the gas storage project officially started in September 2019 and has been basically completed. The second phase of the gas storage project also includes two 160000 cubic meter LNG storage tanks, which are currently in preliminary design. Recently, reporters walked into the site of the first phase of the Guangzhou LNG emergency peak shaving gas source project, and two tall storage tanks rose up like two "fat guardians" guarding the coast of the South China Sea, ensuring the natural gas supply of Guangzhou city. Next to the two storage tanks, there is a dedicated unloading dock for berthing LNG ships, which has also been basically completed. "In the future, the liquefied natural gas on the ship can be directly transported to the top of the tank through the pipeline, and then poured into the tank, and the whole process will be completed automatically." Gao Zhilin, the project contractor and deputy manager of the engineering construction department of Yuehai (Panyu) Petrochemical Storage and Transportation Development Co., Ltd., told reporters. "LNG tanks are full capacity concrete tanks, with a height of about 50 meters, the outer tank diameter of 82 meters, and the inner tank diameter of 80 meters." Gao Zhilin introduced. After the completion of the first phase of the project, it will have a storage capacity of 320000 cubic meters of LNG, which can meet the emergency support needs of Guangzhou for 10 days. After the completion of the second phase of the project, the total storage capacity will reach 640000 cubic meters, which can meet the peak shaving and emergency support needs of natural gas in Guangzhou for 15 days. To improve the safe and stable supply of gas in Guangzhou, "LNG has special physical and chemical properties and needs to be stored below -160 ℃, so there are very high requirements for the thermal insulation and airtightness of the storage tank." Gao Zhilin explained. LNG
