On January 10th, with the last tower properly installed and accurately connected, all of the towers for the blue ocean new materials 1-hexene/1-octene plant – namely the degassing tower, 1-hexene tower, 1-octene tower, and solvent recovery tower – were successfully lifted into place, achieving the remarkable feat of constructing four towers in just three days. This marks the successful completion of the installation of the large towers for this facility, with the project progression shifting entirely from the structural construction phase to the stage of equipment installation and pipeline connection. The centralized lifting of these large towers involves a tight schedule, high intensity, and great difficulty. Among them, the degassing tower, with a total weight of 271 tons, a height of 63.26 meters and a diameter of 4 meters, became the most critical element in the entire lifting operation. To ensure the success of the lifting operation, the project team planned ahead and made systematic arrangements; it developed a detailed special lifting plan, organized technical experts and construction teams to conduct multiple rounds of technical evaluations and simulations, identified potential risk points throughout the entire process, kept records of them, and took action to address those risks. Before lifting each tower, the project team conducts safety and technical briefings for all staff, clarifying job responsibilities, operational standards, and emergency response procedures, thereby establishing a robust safety framework in which \"everyone understands the regulations and everything is covered by safeguards.\" To address the key challenges of 1-hexene tower having the highest height and the weight reduction tower being the heaviest, the project team developed specific stabilization control measures and emergency response plans. Unified command was implemented throughout the lifting process, with dedicated personnel monitoring the equipment’s orientation and lifting parameters in real time, to ensure that all operations were carried out accurately, in a standardized manner, and safely. On January 8, the 1,250-ton main crane and the 350-ton tail crane worked in perfect coordination to lift the weight-reducing tower smoothly and place it in position accurately, setting a successful start for the subsequent lifting operations. After the successful first lifting, all the employees involved redoubled their efforts and worked continuously to carry out the lifting operations for the 1-hexene tower, the 1-octene tower, and the solvent recovery tower. Ultimately, the project team achieved the remarkable feat of lifting four large tower structures within three days, successfully meeting the set goals and thus securing valuable time for subsequent tasks such as pipeline installation, equipment setup, and system debugging.
