On April 10, the hoisting of 48 heat exchangers for the China Energy Engineering Group’s (CEEC) Shandong Tai’an compressed air energy storage project was successfully completed, marking a phased victory in the installation of core equipment and laying a solid foundation for subsequent process pipeline construction and overall commissioning.
The 48 heat exchangers hoisted in this phase include various types such as fixed tube-sheet and U-tube types, with the maximum single-unit weight reaching 159.5 tons. Installed in the compression and expansion sides of the heat exchange zone, the hoisting faced limited space and extremely high precision requirements. The project team pre-developed a special construction plan, simulating equipment access routes and hoisting postures using BIM technology to optimize equipment placement sequences. Adopting a “modular prefabrication + sectional hoisting” model, the team achieved seamless integration between equipment arrival and installation processes, completing up to 4 hoisting tasks per day and effectively shortening the construction period.
The hoisting task received strong support from the project owner, supervisor, and general contractor. The project department jointly convened 6 special coordination meetings with multiple parties to clear equipment transportation routes in advance and ensure the passage of large vehicles. Frontline workers overcame temperature differences between day and night, working continuously to deliver excellent results with a “craftsmanship spirit of excellence.”
Next, the project team will take this opportunity to fully advance subsequent milestones such as process pipeline welding and electrical instrument installation, ensuring high-quality on-time delivery and creating a benchmark quality project.
