On January 9, within the Long Son Oil and Gas Industrial Development Zone in Vietnam, the jacking-up operation of Tank A for the 2×120,000 cubic meter low-temperature ethane storage tank project – which was jointly contracted by China National Chemical Engineering Corporation’s Tianchen Company and Vietnam Petroleum Technology Services Company, with China National Chemical Engineering Corporation’s 10th Construction Company handling the construction work – was a complete success! Wang Songbai, Deputy Secretary of the Party Committee and General Manager of the company, and Ji Jiagen, Deputy General Manager, attended the pneumatic jacking ceremony. From 7:08 to 9:28, over a period of 140 minutes, the giant arch structure weighing 616.095 tons (including its attached facilities) was lifted steadily by 33.805 meters, reaching its designated position with precision. This marks a success in the core installation phase of Vietnam’s first large-scale low-temperature ethane storage tank, representing a crucial step forward in the overall construction of the project. As a key infrastructure for the rapid development of Vietnam’s petrochemical industry, this is China Chemical’s first large-scale cryogenic storage tank project in the Southeast Asian market; it also serves as an example of win-win regional cooperation. The project was funded by a company under **Siam Cement Group (SCGC)**, while China National Chemical 14th Construction Engineering Corporation provided key construction support thanks to its leading technology in low-temperature storage tanks, thereby enabling the effective integration of China’s advanced manufacturing capabilities with local Vietnamese engineering expertise. This cooperation is a practical outcome of industrial chain coordination within the framework of RCEP. It will not only significantly enhance Vietnam’s ability to secure high-quality petrochemical raw materials on its own, laying a solid foundation for it to become an important petrochemical industry hub in the ASEAN region, but it also promotes closer integration between the Belt and Road Initiative and Vietnam’s \"Two Corridors, One Ring\" development strategy. The success of this pneumatic lifting once again demonstrates China Chemical’s core technologies and outstanding engineering capabilities in the field of low-temperature storage tanks. Through this high-quality project, it showcases the responsible brand image of Chinese enterprises that actively participate in international cooperation, share the benefits of development, and contribute to regional energy and industrial upgrading, thereby laying a solid reputation foundation for future cooperation in the Southeast Asian market.
