At 15:58 on June 4, 2026, amidst the festive sound of firecrackers, the main structure of Cooling Tower No.6 for the 1×660 MW unit at the Shandong Dongying project, constructed by our company, was successfully topped out. Since the concrete pouring for the lower ring beam of Cooling Tower No.6 began on December 17,2025, all project personnel have worked collaboratively and persistently to complete this critical milestone, laying a solid foundation for subsequent equipment installation, system commissioning, and successful water testing.

The No.6 cooling tower represents a typical tall structural engineering project characterized by stringent construction standards, significant safety risks, and rigorous quality control requirements. The construction period spans the winter low-temperature season, compounded by objective challenges such as the tower's considerable height, concentrated high-altitude work activities, and limited working space, which substantially increase the difficulty of on-site construction.

To address various high-risk management challenges—including difficulties in installing safety harnesses at heights, multi-layered crossover construction, and intensive core tower operations—the project team adopted a safety-first approach with comprehensive closed-loop control measures to effectively resolve these issues. Specific controls were established for crossover and high-altitude work; protective measures and safety harness attachment points were optimized; work was strictly divided into zones and scheduled by time slot to prevent disorderly crossover activities; daily pre-shift safety briefings for high-risk tasks, continuous on-site supervision, and dynamic hazard identification and rectification were implemented, with particular focus on critical areas such as edge protection, lifting operations, high-altitude work, and multi-level crossover operations, thereby reinforcing safety responsibilities at every level. Through the project team's rigorous oversight and thorough implementation, the project achieved zero violations and zero safety incidents throughout its entire construction period, ensuring steady progress through a robust safety management system.

While ensuring robust safety controls, the project team consistently prioritizes engineering quality, implementing each construction procedure with high standards and strict compliance. To address challenges posed by low temperatures during winter—such as poor concrete performance, difficult curing conditions, and difficulties in maintaining structural accuracy—the team strictly adheres to the specialized winter construction plan, meticulously controlling material ratios, layer thicknesses during pouring, vibration density, and thermal insulation and curing measures. Key processes including tower wall profile, structural dimensions, and joint treatment undergo comprehensive monitoring and thorough quality inspection throughout the entire workflow, ensuring no corners are left unattended and standards remain uncompromised. This approach fully guarantees that both the structural integrity and visual appearance of the cooling tower meet all requirements, laying a solid foundation for project quality through meticulous craftsmanship.

The successful completion of the No.6 cooling tower marks a significant milestone, demonstrating both robust safety management and exceptional engineering quality from the project team. It fully reflects the outstanding spirit of all participants—unafraid of harsh conditions, determined to overcome challenges, and committed to practical responsibility.

Next, the project team will maintain strict vigilance regarding safety production, continuously enhance refined and standardized safety management on-site, rigorously uphold safety standards, strictly control quality requirements, meticulously manage construction timelines, and steadily advance all subsequent construction tasks to ensure the project achieves its objectives with high quality, efficiency, and safety.
