en.Wedoany.com Reported - The six key core units of the CNOOC-Shell Huizhou Phase III Ethylene Project, located in the Daya Bay Petrochemical Zone in Guangdong, China, have fully entered the prefabrication and installation stage for steel structures. This marks a smooth transition from civil foundation construction to the core process of steel structure installation.
To ensure the timely and smooth commencement of steel structure prefabrication and installation, the project team adopted a holistic approach, focusing on precise execution. They implemented comprehensive control measures across safety, quality, and technical dimensions, formulating a series of targeted safeguards to establish a solid foundation for smooth construction progress.
The project team prioritized design collaboration upfront, efficiently resolving bottlenecks in drawing issuance. By dispatching equipment and piping engineers to participate in the 3D model review at the design institute, they streamlined the design output process for structural disciplines. Furthermore, they proactively engaged with the design institute during the early design phase to clarify main steel structure parameters. This information was simultaneously provided to the construction contractor, enabling them to secure raw material suppliers and lock in prices in advance, ensuring timely supply and achieving cost control.
The project team implemented full-process control over steel structure manufacturing, transportation, and installation. They organized specialized technical briefings, clearly defining anti-corrosion and fabrication standards. The team also supervised the construction contractor and component manufacturers to strictly adhere to process control requirements, verifying key steps such as production, processing, and on-site delivery one by one. This ensured that component quality remained controllable and compliant throughout the entire process, fundamentally preventing quality risks.
Civil foundations are a crucial prerequisite for steel structure prefabrication and installation. The project team launched a focused effort on the foundation work for the steel structure frames of each unit, implementing closed-loop control over the entire process of key construction phases like foundation work. Through the project team's on-site command, supervisory oversight, and the construction contractor's dedicated efforts, the civil foundation construction was completed ahead of schedule to a high standard, laying a solid groundwork for subsequent work.
The project team maintained a parallel focus on safety and technology, conducting specialized safety briefings for activities like steel structure loading, transportation, and unloading, thereby reinforcing safety responsibilities for all personnel. Concurrently, they urged the construction contractor to develop a specialized construction plan for steel structure installation, ensuring technical control from the source, improving risk prevention measures, and guaranteeing that the installation work proceeds safely, in compliance with standards, and in an orderly manner.
The CNOOC-Shell Huizhou Phase III Ethylene Project entered full-scale construction in January 2025. The project involves the construction of a 1.6 million tons/year ethylene cracker, along with 16 downstream chemical production units and supporting facilities. Upon completion, CNOOC-Shell's total ethylene production capacity will reach 3.8 million tons/year, maintaining its position as China's largest single-site ethylene plant and the ethylene production base with the largest scale.
