[Haichuan Overseas Engineering] Successful one-time lifting of the heavy framework for the low-pressure elevated flare system in the Amira public works project in Saudi Arabia, carried out by Jilin Chemical Construction Corporation

Thread Content

On October 16 local time, the heavy framework of the low-pressure elevated flare tower for the Saudi Amira public works project, carried out by Global Jilin Chemical Construction’s international branch, was successfully lifted in one go. This successful lift enabled precise connection between the second framework and the main steel structure of the first framework, laying a solid foundation for the timely assembly of the next section of the flare tower. It marks the entry into the critical phase of lifting the heavy frameworks for this flare tower, which is the highest in height among those in the project. It is reported that the low-pressure elevated flare is the tallest iconic structure of this project, standing at 175 meters in height and weighing approximately 650 tons; its framework is assembled in 7 sections. For this heavy lifting and alignment task, the construction team carried out the work section by section, using Demag cranes as planned. To ensure the safe, high-quality, and efficient completion of this heavy-frame lifting task, the project team leaders took charge of directing the operations. They organized a team specialized in equipment management and worked together with the local Saudi company AL JABER Heavy Lifting to develop a lifting plan and a coordinated work approach. Detailed plans were made for the sequence of lifting operations, the routes taken by the machinery, as well as the processes for adjusting, connecting, and securing the joints at the torches, which were to be handled by the riveters; this resulted in a comprehensive construction plan for overseeing the entire process. At the same time, the project team deployed 160-ton hydraulic cranes, 135-ton crawler cranes, and 80-ton hydraulic cranes, and coordinated three lift trucks and other mechanical equipment to assemble the steel structures of the second to seventh sections of the torch in groups. During the process, engineers guided the workers according to the design drawings to carry out precise assembly, and closely monitored various steps such as the verticality of each steel structure section, the tightening of bolt torques, surface repainting, and the lifting of components. By ensuring strict control over safety and quality, they laid a solid foundation for the successful completion of the lifting operations. During the lifting and alignment process, the project team used a 1250-ton Demag crane to lift the 81-ton steel framework of the second section of the low-pressure overhead flare tower smoothly ； A 600-ton Terex crane uses a lifting frame to transport the rigger to a safe area at the same horizontal level as the location where the frame is to be installed. Through precise lifting, translation, and positioning, the second frame section was successfully connected to the steel structure of the first frame section. The on-site manager of the Amira project for the client praised the project team for their careful organization, rapid response, and close cooperation in lifting the heavy framework of the low-pressure overhead flare tower, enabling the task to be completed safely and to a high standard. He considered the construction team working on the Amira project to be a team with excellent technical skills, the ability to handle challenging tasks, and great resilience. Moving forward, Huanqiu Jilin Chemical Construction will continue to uphold a work attitude of \"strictness, meticulousness, practicality, and speed\", coordinate the progress of construction activities, ensure that all project milestones are successfully achieved, and deliver satisfactory results to the client.
