[Haichuan Overseas Engineering] The pneumatic jacking of all large-scale cryogenic storage tanks for the Longshan project in Vietnam was successfully completed

Thread Content

Recently, the Long Son low-temperature storage tank project in Vietnam, which was jointly general contracted by China National Chemical Corporation Tianchen and Vietnam Petroleum Technology Services Company, successfully completed the pneumatic jacking of all the large-scale low-temperature storage tanks. This milestone was achieved 43 days ahead of the original schedule, indicating that the most critical and technically challenging installation phases of the project have been completed safely, with high quality and efficiency. As a result, the project progress is now on fast track, securing valuable time for the subsequent construction steps. Gas head lifting in low-temperature storage tanks is a critical process in the construction of large-scale low-temperature storage tanks, characterized by high technical complexity and strict safety requirements. This project involves two storage tanks with a capacity of 120,000 cubic meters each; their dome structures are very large, and the lifting process requires millimeter-level precision and stability control, which imposes high demands on construction organization and technical management. Leveraging its extensive technical expertise and proven engineering experience, Tianchen Company’s project team quickly replicated and optimized the successful methods used for the first air-jacking operation, enabling continuous work and repeated successes. This demonstrates Tianchen Company’s strong capabilities in organizing the construction of complex large-scale equipment systems, ensuring standardized operations, as well as maintaining control over safety and quality. Since the project began, facing various challenges such as a complex construction environment in overseas projects and difficulties in resource allocation, the project team maintained a high level of determination, adhering to the principle that \"the start is the moment of sprinting, and the beginning is the stage of decisive action.\" By making full use of the advantages of EPC turnkey management, they carried out systematic planning and careful organization. Through lean management and proactive resource allocation, they managed to combine two key milestones, and completed all the large-scale lifting operations for the low-temperature storage tanks at high quality and efficiency, in line with the \"Tianchen speed.\"
