Recently, the six key core units of the CNOOC Shell Huizhou Phase III ethylene project, located in the Daya Bay Petrochemical Zone, have entered the stage of prefabricated steel structure installation, successfully transitioning from the construction of civil foundations to the critical process of steel structure installation. To ensure the smooth commencement of the prefabricated installation work for the steel structure, the project team took a comprehensive approach and focused its efforts precisely, emphasizing control over all aspects such as safety, quality, and technology. A series of targeted safeguards were established to lay a solid foundation for the smooth progress of the construction. The project team adhered to proactive collaborative design to efficiently overcome bottlenecks in output generation. By sending engineers specializing in equipment and piping to participate in the review of 3D models at the design institute, the pathway for producing design drawings by structural engineers is established. At the same time, during the early stages of design, proactive contact is established with the design institute to determine the key parameters of the steel structure, which are then provided to the construction party. This helps them identify raw material suppliers and prices in advance, ensuring timely supply and enabling cost control. The project team implements comprehensive control over the entire process of steel structure manufacturing, transportation, and installation. It conducts specialized technical briefings to establish clear standards for corrosion prevention and processing, and urges the construction units and component manufacturers to strictly adhere to the requirements regarding process control. Key stages such as production, processing, and delivery are checked one by one to ensure that the quality of the components remains under control and meets all regulatory standards, thereby preventing potential quality issues from arising. The civil engineering foundation is an important prerequisite for the prefabricated installation of steel structures. The project team carried out targeted efforts on the foundations of the steel structure frames for various installations, implementing comprehensive closed-loop supervision over key processes such as foundation construction. With the project team providing on-site supervision, the supervisors overseeing the work closely, and the construction units making every effort to complete their tasks, the civil engineering foundation was built to high standards ahead of schedule, laying a solid foundation for subsequent construction works.
