Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On April 29th, it was reported by Offshore Oil Engineering Co., Ltd. that China’s first 50,000-ton class tension jack-based loading system, developed under the leadership of this company, has been delivered. All of its key components are domestically produced, and its overall performance meets international advanced standards, marking a significant breakthrough in China’s capabilities in manufacturing marine engineering equipment. Shipment is an essential step in offshore engineering construction, among which towshipping is the most common method for shipping super-large structures such as the jacket of offshore oil and gas platforms. Towing loading onto a ship relies on a jack towing system, which pulls the structure onto the ship in a manner similar to tug-of-war. As the \"powerhouses\" for tow loading, the research, development, and manufacturing technology for 50,000-ton-class tension jacks has long been in the hands of a few international manufacturers, resulting in high costs for purchasing or leasing such equipment. The pull jack loading system delivered this time consists of 10 1,000-ton pull jacks, 4 1,000-ton pushing jacks, a power station, a control system, and fixed anchor points. Based on the standard friction coefficients for loading, its maximum pulling capacity can reach 50,000 tons. The system uses high-strength alloy materials, resulting in a tensile strength coefficient 20% higher than that of conventional materials, and a loading speed that is 15% faster than that of similar international equipment. The system has been certified by the French Classification Society, and its overall performance is at the world’s advanced level. Over the past decade, CNOOC Engineering has completed the towing and loading of approximately 300 structures, of which 34 were structures weighing over 10,000 tons. With the introduction of the 50,000-ton pulling jack towing and loading system, China’s capacity for installing offshore oil and gas platforms will be significantly enhanced.
