Blue Ocean New Materials, First Lift Breaks Through!

The FDPE unit, undertaken by the Nantong Blue Sea New Materials Polyethylene Project Department of the Fifth Branch, reached a critical milestone as the de-light tower (3200-C-3201) was successfully hoisted into place. As the first of the six towers in the unit to be hoisted, this successful "first lift" laid the foundation for the subsequent concentrated hoisting of similar equipment. It also marked the full commencement of large-scale tower installation engineering for the unit, representing a landmark achievement for the overall project schedule.

The light-ends removal column is one of the key process components of the FDPE unit. After the installation of insulation and internal/external attachments, the equipment has a total weight of 265 tons, a height of 51.56 meters, and a diameter of 4 meters. It is characterized by its massive scale and stringent requirements for hoisting precision.

To ensure the smooth completion of the hoisting task, the project team meticulously planned the hoisting scheme, adopting a collaborative operation mode with the XGC16000 1250-ton crawler crane as the main hoist and the CC2200 350-ton crawler crane as the auxiliary hoist. They precisely completed key procedures such as equipment turning, lifting, and positioning. The entire hoisting process was fully controlled and orderly, with all technical parameters strictly conforming to the scheme requirements, ultimately achieving a successful hoist on the first attempt.

As the first of six towers in this unit, the lifting of the debut tower holds demonstrative and leading significance in construction organization and technical execution. Faced with practical challenges such as complex lifting conditions and limited operating space, the project team conducted multiple rounds of technical argumentation in the early stages, continuously refining and optimizing the lifting plan. Special analysis was focused on key aspects like equipment stress calculation, lifting radius control, and operational path layout, resulting in a scientific and comprehensive technical solution that provided reliable technical support for on-site lifting operations.

During the hoisting phase, project management personnel provided close-range, front-line command throughout, strictly adhering to the approved construction plan and safety technical disclosure requirements. On-site, each operational position, including hoisting, commanding, and supervision, had clear divisions of labor and smooth coordination. The hoisting equipment operated steadily, command signals were transmitted clearly and accurately, and the work pace was reasonably controlled, fully demonstrating the outstanding comprehensive capabilities of the Fifth Branch Company in organizing and coordinating large-scale equipment hoisting and site management.

The successful lifting of the demethanizer tower is just the first of six towers in the FDPE unit. According to the construction plan, the remaining five towers will be lifted in succession in the near future. Subsequent tasks face multiple challenges, including heavy equipment weight, dense tower distribution, and tight schedule coordination, which place higher demands on project coordination capabilities. Next, the Nantong Blue Ocean New Materials Full-Density Polyethylene Project Department of the Fifth Branch will take the successful lifting of the first tower as an opportunity to continuously strengthen construction organization management and process control, steadily promote the installation of subsequent equipment, and build a solid guarantee for the high-quality construction of the project and the smooth realization of key node goals.
