Hoisting and installation of the high-pressure flare discharge tank for the Ningxia Baofeng project completed
Thread Content
The high-pressure flare discharge tank for Ningxia Baofeng’s 500,000 tons per year coal-to-olefins project has been successfully hoisted into place. To ensure the success of the lifting operation, the project team developed a specialized lifting plan, implementing strict control over all aspects of the process, including technology, safety, and equipment. Focusing on the key aspect of foundation bearing capacity, the project team completed the reinforcement work by laying 500 mm thick layers of sand and gravel in advance; professional tests confirmed that the foundation bearing capacity met all requirements ； A road base plate is laid fully under the tracks of the main crane, which effectively distributes the load and eliminates the risk of settlement, thus providing a solid safety foundation for lifting operations. The successful hoisting of this high-pressure flare discharge tank marks a significant breakthrough in the installation of the core equipment for the flare unit of the project’s polypropylene plant, laying a solid foundation for subsequent pipeline connections, system commissioning, and the overall commissioning of the project.
The electrical cable trays for the Fujian Gulei Zhongsha C4 hydrogenation project have been fully installed across the entire length of the facility. The electrical cable trays, which are 1,590 meters in length, were installed as part of the project undertaken by the Fifth Engineering Company; this completion removes a key obstacle to the subsequent installation and testing of the electrical system. Serving as the \"lifeline\" for power transmission in the project, this electrical tray covers key areas such as full hydrogenation, pipe galleries, and selective hydrogenation, and undertakes the important task of protecting the installation of power and control cables. To address the challenges in construction, the project first developed a 20-meter model section, establishing 8 standards including the precision required for the installation of supports and hangers. By adopting a approach based on \"model guidance, widespread observation by all staff, and standardized procedures\", it ensures consistent construction quality. At the same time, the safety threshold is always maintained strictly, and measures such as protection for work at heights and control of hot work are implemented rigorously to ensure zero safety incidents throughout the entire construction process.
