Create a new chemical logistics route in the Bohai Bay! Construction of the country’s largest liquefied hydrocarbon terminal area is advancing at full speed. Publication date: 2025-10-21. By the Bohai Bay, with the sound of waves in the background ； Inside Huanghua Port, there are numerous storage tanks. Recently, the EPC project for the liquid chemical terminal area in the Huanghua Port Comprehensive Port Area, carried out by China State Construction Installation, has completed the construction of the bodies of 21 storage tanks as well as the installation of process pipelines in the main corridors, and is now making every effort to meet the completion deadline. The on-site construction is progressing in an orderly and intense manner, with a busy atmosphere everywhere. As a key project in Hebei Province, the project is located in Cangzhou, Hebei, with a total tank capacity of 460,000 cubic meters. Once completed, it will further enhance the comprehensive service capabilities of Huanghua Port, strengthen its radiating influence, improve its ability to support the coordinated development of the Beijing-Tianjin-Hebei region, and contribute to the creation of a world-class port cluster in this area characterized by complete functions, reasonable division of labor, differentiated development, and efficient coordination. One company is responsible for the construction of 21 storage tanks and related facilities, with a total tank capacity of 139,000 cubic meters. ingenious honeycomb design for complete safety. As the largest liquefied hydrocarbon terminal complex in the country, to ensure the safety and efficiency of the 8 chemical storage tanks, the project team innovatively adopted a fully liquid-contacting honeycomb-style stainless steel double-disc internal floating roof. Each tank’s internal floating roof is composed of 180 precisely assembled honeycomb-shaped modules, which allow it to fit tightly against the liquid level inside the tank. This helps to minimize any reaction between the liquid and air, thereby ensuring the quality of oil storage from the source and avoiding safety risks that could arise from contact between liquid and gas. At the same time, this floating roof goes beyond the limitations of traditional structures by adopting an innovative beamless design, which helps to reduce its own weight and the loading on the storage tank, thereby significantly enhancing the structural stability and safety. During construction, the project adopts a \"factory-prefabricated + modular construction\" approach. For the internal floating roof modules, laser seam-tracking robots and fully enclosed TIG welding processes are used to ensure the sealing of the welded areas, effectively preventing the risk of liquid leakage and achieving a 100% success rate in air-tightness tests. During the assembly phase, workers only need to precisely assemble the various modules outside the tank in accordance with the design requirements, and then lift them as a whole into the tank for connection and fixation. This simplifies the construction process, eliminates all safety risks associated with welding work inside the tank, and reduces the construction time by about 30 days, thereby laying a solid foundation for the rapid deployment of the storage tank and its long-term stable operation.
Integration of digital and traditional technologies for efficient construction: d2b0dc7c207688d93abacc3f173d98ff.jpg Since the project is located near the sea, the land at the site was created through land reclamation, resulting in soft soil foundations. To prevent settlement of the 21 storage tanks, the project adopted an innovative \"bamboo-joint pile\" technique during foundation construction. By arranging ring-shaped protrusions at regular intervals along the axial direction on the outer wall of the piles, a structure similar to that of bamboo joints was created, which increased the frictional resistance of the piles. This approach boosted the vertical bearing capacity of each pile by 20%, ensuring the stability of the storage tanks and the overall structure. Moreover, it reduced the construction time by 20 days compared to traditional pipe pile methods. c0b25daad6336f82b09ee206be74de15.jpg For the rust removal and repainting of the welds on the inner walls of storage tanks, the project team employed multi-functional wall-crawling robots. By remotely controlling these robots, tasks such as rust removal, cleaning, grinding, and painting could be carried out, which significantly reduced the safety risks associated with working in confined spaces inside the tanks. The efficiency of these robots was equivalent to that of 10 workers working simultaneously; it took only 20 days to complete 9,500 square meters of rust removal and painting work.
The project team applies lean management throughout the entire project lifecycle, using standardized and intelligent methods to enhance control efficiency. By utilizing the company’s innovatively developed \"Smart Cloud Box\" system for temporary power supply, it is possible to monitor, make decisions, and control all electrical data related to equipment through smartphones, computers, and a central control unit. This enables automatic fault detection, real-time tracking, and automatic handling of issues, creating a closed-loop system that enhances the safety of electrical management. It can also accurately identify electricity demand in different areas and at various times, automatically optimize power supply strategies, and ensure that electrical appliances turn off automatically after work or during lunch breaks, thereby reducing overall energy consumption by approximately 13%. 15b2607f332d561737f712de91359673.jpg The project team has also introduced the PIMCenter project management system to precisely monitor the progress of construction, identify any deviations in schedule promptly, and take effective measures to make adjustments. It also enables data sharing and collaborative work among the parties involved in construction, supervision, design, and implementation, thereby significantly improving communication efficiency, reducing communication costs and errors in information transmission, and allowing for effective control over project progress, safety, and quality. During construction, the project won first place in the owner’s comprehensive evaluations for safety, quality, and progress on six consecutive occasions. The effectiveness of its lean management practices was evident, earning high recognition from all parties involved. By the Bohai Bay, thousands of sails race against each other ； Nenghua New Port – setting sail on a new journey. CCEC Installation makes full use of its expertise in the energy and chemical sector, actively contributing to the strategy for the coordinated development of the Beijing-Tianjin-Hebei region. Through smart construction methods and sustainable practices, it has created the largest liquefied hydrocarbon terminal complex in the country, thus offering a valuable contribution to the development of a world-class port network with comprehensive functions and efficient coordination
