On April 24th, the first phase expansion project of China National Offshore Oil Corporation’s (CNOOC) “Green Energy Port” in Yancheng achieved a significant milestone. This project, which is the largest liquefied natural gas (LNG) storage base in China, successfully completed the construction of six LNG tanks, each with a maximum capacity of 270,000 cubic meters. This achievement is notable as it marks the completion of the main construction phase for the first batch of 270,000 cubic meter LNG tanks in the country, offering valuable insights for the future development of ultra-large LNG tanks in a more efficient and streamlined manner.

What’s particularly noteworthy about this construction phase is the innovative use of perlite filling technology, representing the first application of automatic vibration compaction technology in China. This approach is a testament to the forward-thinking nature of the development efforts at Yancheng’s “Green Energy Port”. Compared to traditional manual compaction methods, this technology not only accelerates the construction timeline for each tank by 7 to 10 days but also enhances overall construction efficiency by nearly 20%. Its successful implementation underscores its potential for widespread adoption and future application in similar projects.
