Recently, the jacking-up of the third 89,000 m³ low-temperature butane storage tank at the Haizhou Bay storage area project in Jiangsu was successfully completed, through EPC general contracting by China Fifth Ring Engineering Co., Ltd., which is affiliated with China National Chemical Corporation. The Liquefied Hydrocarbons Storage Area and Associated Pipeline Project of Jiangsu Haizhou Bay CNPC Energy Co., Ltd. is located in the Ganyu Marine Economic Development Zone of Lianyungang City, Jiangsu Province. The project plans to construct 2 double-metal fully enclosed low-temperature C3 storage tanks with a capacity of 89,000 m³ each, 1 C4 storage tank, 6 normal-temperature spherical tanks with a capacity of 3,000 m³ each, as well as associated process equipment and auxiliary facilities. The low-temperature storage tanks for this project will be constructed using Wuhuan’s proprietary technology, which is highly reliable. Once the project is operational, it will be able to function efficiently and stably, meeting the demand for LPG products in the local and surrounding markets. The successful completion of the erection of the third 89,000 m³ low-temperature butane storage tank for this project lays a solid foundation for the subsequent construction of the inner tanks and the overall completion of the project. As a key part of tank construction, pneumatic jacking involves lifting the arch structure, which weighs hundreds of tons, to a height of over 40 meters with precision; this process demands high levels of technical accuracy, strict safety controls, and effective team collaboration. During this pneumatic lifting operation, the company’s project team carried out scientific planning and efficient construction, overcoming challenges such as adverse weather conditions and the complexity of concurrent tasks. By optimizing the pressure balance system and implementing digital monitoring throughout the process, the lifting accuracy was maintained at the millimeter level, with zero accidents or defects throughout the operation. This once again demonstrated the company’s leading technical expertise and excellent management capabilities in the field of low-temperature storage tanks.
