Maoming Gravity undertook the shipment of the cracking furnace for CNOOC Shell Huizhou Phase III
Thread Content
According to Sinochem New Network, on April 8, the whistles at the Maoming Petrochemical Port blared as the \"giant\" module for the ethylene cracking unit in Phase 3 of CNOOC Shell Huizhou, weighing over 2,000 tons, was officially shipped off for delivery to the Daya Bay Petrochemical Zone in Huizhou. This marks the first time that Maoming Gravity Petrochemical Equipment Co., Ltd. has systematically overcome the technical challenges associated with the modular design, integrated manufacturing, loading/unloading, and transportation by sea or land of large-scale ethylene cracking units, taking an important step forward in the field of fully modular manufacturing of ultra-large petrochemical equipment. This unit features a modular design for fabrication, transportation, and installation as a complete unit, including all internal components such as primary quench heat exchangers, thereby enabling an \"plug-and-play\" delivery of ultra-large ethylene cracking furnaces. Since the project began in May 2025, Maoming Gravity has pooled its key resources to form a dedicated team to tackle various challenges. The team has successfully overcome a series of critical technical hurdles, including the design and calculation of the overall modular structure, control of welding deformation, high-precision lifting, installation of quenchers in complex spaces, welding of critical joints, as well as calculations related to load distribution at the dock and reinforcement for land and sea transportation. By innovatively applying advanced methods such as \"horizontal assembly + vertical lifting,\" \"double-machine lifting,\" and \"lateral translation lifting,\" the team was able to deliver the first cracking furnace module with high quality, earning full recognition from CNOOC Shell Petrochemical Co., Ltd. and Sinopec Engineering Construction Co., Ltd. CNOOC Shell Huizhou Phase III Ethylene Project is a **major strategic integrated refining and chemical project** with a total investment of 48 billion yuan; once completed, it will become the largest single ethylene production facility in China. The 1.6 million tons per year ethylene cracking unit is the core of this project, and the ethylene cracking furnace, as the \"heart\" of the unit, has its technical level, manufacturing quality, and degree of integration directly determining the operational efficiency and safety stability of the entire facility. The successful shipment of this fully modular pyrolysis furnace represents yet another major piece of equipment developed by Maoming Gravity to meet the petrochemical industry’s demands for standardized design, factory-prepared components, and complete furnace delivery in petrochemical equipment.
Equipment manufacturing has reached a new level; before, welding was done on-site
Maoming Gravity used to be able to produce only segmented modules for pyrolysis furnaces, but its business scope has now expanded.
Bro’s right; this is indeed a significant breakthrough for Maoming Gravity, marking the shift from segmented subcontracting of cracking furnaces to modular delivery of entire furnaces. This shipment of the entire furnace not only presents increased manufacturing challenges but also requires solving issues related to the stability calculations for transporting such large modules, as well as the design of lifting equipment at ports. For transporting items weighing over 2,000 tons by sea, it is necessary to obtain temporary permission from maritime and waterway authorities in advance. There are few domestic equipment manufacturers capable of handling the entire process, and this project serves as a model for standardization in the field of modular petrochemical equipment in China.
