The first storage tank of the Fujian LNG receiving station project was successfully completed; the pneumatic jacking operation for the roof of the second storage tank was also a success. On October 18, good news came from the construction site of the Fujian LNG receiving station project: the pneumatic jacking operation for the roof of the second storage tank, which is one of the key facilities of the project, was carried out successfully. The massive steel arch, weighing around 900 tons, was lifted with precise control to its intended position at the top of the tank, at a height of nearly 40 meters, marking the achievement of a key milestone in the project. This tank has now moved from the civil construction phase to the stage of installing the interior components, representing a significant and milestone-like advancement in the project’s development. The entire roof-raising process was live-streamed using multimedia, with leaders from various units observing it in the command center hall of the Fujian LNG project. Wang Haisong, a member of the Party Committee and deputy general manager of the company, and Liu Xiaoping, assistant to the general manager and Party secretary of the East China branch, attended the observation ceremony. Powered by technology for precise control: \"Air\" lifts heavy loads to create miracles. Air lifting is one of the most technically challenging, risky, and complex processes in the construction of large LNG storage tanks. Its working principle: A fan system is used to continuously supply air into the enclosed space inside the tank, causing the pressure inside the tank to rise slowly and steadily, thereby generating a strong upward buoyant force. This “invisible giant hand” steadily pushes upward along the tank wall the entire dome structure that is sealed to it, until it reaches the designated position with precision. The entire process is akin to \"crowning\" a storage tank, requiring millimeter-level precision control and absolute balance and stability. Early in the morning on the 18th, the members of each lifting team began preparing according to the planned schedule. The control room staff are in place, the recording equipment is turned on, and communication is normal ； The personnel for the wind turbine unit are in place, the generator has been started, and the equipment is operating normally ； The inspection team has arrived, unrelated personnel have been evacuated, and the security zone is in order ； The measurement team is in place, the measuring tools are secured, and communication is normal ； Reports from various teams came in over the walkie-talkie, to finalize confirmation of their respective job responsibilities. At 7:08, with the order given by the chief commander, the air lift operation officially commenced. During the dome-raising process, the project team utilized advanced automatic monitoring and control systems to conduct real-time tracking and adjustment of thousands of parameters such as the dome’s posture, wind speed, and air pressure. After several hours of continuous work, at 09:15, the dome was successfully brought to the designed elevation and perfectly aligned with the pressure ring on the top of the tank, a process that took 127 minutes. Overcoming difficulties together: Excellence in construction leads to high-quality projects. The Fujian LNG receiving station project is located on the southeast coast and faces various natural challenges such as typhoons, the rainy season, and high temperatures and humidity. To ensure the success of this critical phase involving gas lift, the project team established a dedicated task force as soon as the construction of the tank foundation began. Through scientific planning and meticulous organization, a series of challenges were overcome, including complex construction techniques, numerous concurrent tasks, and high precision requirements. During the preparation phase prior to gas lift, the project team organized experts to conduct repeated evaluations and optimizations of the construction plan, and provided thorough technical briefings and safety training to all participants. The on-site workers worked day and night, conducting dozens of inspections and tests on key components such as the balancing system, sealing system, and power supply system, to ensure that the lifting system was in optimal condition. With a rigorous attitude, professional skills, and a tenacious spirit of effort, the project team cleared all obstacles on the way forward, laying a solid foundation for the complete success of the air lift. Led by Party building, uniting efforts: The red engine accelerates progress. In the process of overcoming challenges in projects, strong Party building work serves as an irreplaceable \"red engine\". The project’s Party branch insists on integrating Party building work closely with project construction. By carrying out activities such as \"pairing Party members with work teams for joint development,\" it fully leverages the exemplary role of Party members, injecting strong motivational force rooted in socialist ideals into the project construction and ensuring that the Party flag flies high at the construction sites. During the preparation and implementation of the air lift, the party branch played a full role as a fighting stronghold, organizing party members and key cadres to take the lead in carrying out the most critical tasks and serving in the toughest positions. They actively carried out ideological mobilization to unite the efforts of all parties involved in the project, creating a strong collective force with shared goals and concerted efforts. Through activities such as labor competitions and technical challenges, the work enthusiasm and creative vitality of all construction workers have been effectively stimulated, transforming the Party’s political and organizational advantages into a strong driving force for the high-quality development of the projects. Laying the foundation and shaping the future, the project has entered a new phase of development. The successful completion of the pneumatic jacking of Tank No. 2 signifies significant progress in the construction of the project’s core tanks; it creates the necessary prerequisites for subsequent tasks such as the installation of internal tanks, insulation work, and the connection of process pipelines, thereby greatly accelerating the overall progress of the project. The success of this gas lift not only demonstrates China’s increasingly sophisticated technical capabilities in the construction of large-scale LNG storage tanks, but also strengthens the confidence and determination of all participating parties to complete all project tasks on schedule and to high quality. We will continue to uphold the spirit of craftsmanship aimed at excellence, and with greater enthusiasm, more scientific management, and a more rigorous approach, we will devote ourselves fully to the subsequent construction efforts to ensure that this project becomes a top-quality project that is safe, reliable, technologically advanced, and of excellent standard.
