On January 8, the degassing tower for the 1-hexene/1-octene unit of Blue Sea New Materials Co., Ltd.’s high-end polyolefin new materials project was successfully lifted, thus accelerating the further construction of the project. This lifting operation is not only the first lift of this device but also the ‘first lift’ for this project after the New Year, laying a solid foundation for all lifting activities throughout the year. It is reported that the facility comprises four towers, among which the degassing tower is a key piece of equipment in the separation process of the 1-hexene/1-octene plant. It is also the heaviest device in the entire facility, weighing 328 tons. Due to its complex structure, high requirements for lifting precision, and limited space for on-site operations, it represents a major challenge during the construction of the facility. For lifting, a 1,250-ton crawler crane is used as the main lifting device, while a 350-ton crawler crane is used to assist in lifting the rear part; this approach takes full advantage of the strong flexibility and stable load-bearing capacity of large crawler cranes. According to CPECC First Construction Company, at the lifting site, under the unified instructions of the chief commander, the two cranes operated in a \"master-slave coordination\" mode, with the operators using their skilled techniques to precisely control the lifting speed and angle. The various teams worked closely together to carry out tasks such as command transmission and safety supervision, ensuring that the entire process proceeded in an orderly manner with smooth coordination. After 1 hour of precise operation, the weight-reduction tower was successfully positioned, completing the lifting task successfully. The successful lifting out of the weight-reduction tower not only demonstrated the team’s technical expertise and ability to work together effectively, but also marked the transition of the project from the infrastructure construction phase to the stage of installing the core equipment. CPECC’s First Construction Team stated that it will promptly begin preparations for lifting the next piece of equipment, in order to lay a solid foundation for the project’s timely commissioning.
