Recently, the jacking operation of the 60,000 m³ butane storage tank for the Guangdong Jieyang LPG project, which was constructed through EPC general contracting by China Wuhuan Engineering Co., Ltd. under China Chemical Engineering, was successfully completed, and the project has now entered the phase of installing the inner tank. Located in the Dainanhai Petrochemical Industrial Zone of Jieyang City, this project involves the construction of an LPG storage and distribution facility covering an area of about 300 mu, with a total tank capacity of 288,000 m³, along with related supporting facilities. It is a key energy infrastructure project in Jieyang City, Guangdong Province. Once completed, it will fill the gap in high-grade LPG storage facilities in Jieyang City, providing raw materials for chemical enterprises in the Dainanhai Petrochemical Industrial Zone, as well as ensuring a stable supply of gas for CNOOC and residents and industrial users in eastern Guangdong. At the same time, the project is interconnected with the terminal and onshore tank farm projects in the Nanhai operation area of Jieyang Port; upon completion, it will further contribute to the development of an energy hub in the Guangdong-Hong Kong-Macao Greater Bay Area. The butane storage tank that has undergone pneumatic jacking this time is one of the two 60,000 m³ bimetallic full-volume tanks included in the project construction. This process has a complex structure and extremely high safety requirements. The operation officially began at 7:40 and was completed by 10:00 a.m., with contact between the top part and the pressure ring achieved after 140 minutes; all technical parameters met or exceeded the design standards. Air lifting operations are one of the most technically challenging and critically important processes in the construction of large storage tanks, requiring stringent risk management. During the construction process, the project team worked together with all parties involved to ensure a safe, controllable, precise, and efficient roof-raising process through measures such as full-process monitoring and repeated drills of emergency plans.
