Jingmen Hongtu Company has completed the assembly of all 12 hydrogen storage tanks with a capacity of 3,000 cubic meters for Oman’s Dukhum 3 million tons per year green hydrogen project

Recently, in Oman in the Middle East, all 12 hydrogen balloon tanks with a capacity of 3,000 cubic meters, constructed by Jingmen Hongtu Company, were completed and assembled. Each of these spherical tanks has a diameter of nearly 18 meters, and they are designed to serve Duqom’s 3 million tons per year green hydrogen project. This project is the largest green ammonia facility in the Middle East (powered by renewable energy sources such as wind and solar power, it produces hydrogen through water electrolysis and then combines this hydrogen with nitrogen to create ammonia). Despite being exposed to high and low temperatures, these large spherical tanks maintain excellent sealing and corrosion resistance. Equipped with dual detection systems of high-definition imaging and infrared flames, as well as a safety instrumented system, they enable pressure monitoring, valve interlocking, and automatic activation of fire suppression systems. Additionally, they support remote diagnosis to ensure safe operation over extended periods of time. The completion of the assembly of these spherical tanks marks a significant step forward in the development of Oman’s Dhofar Hydrogen Energy Hub, and behind this progress are the efforts and dedication of the builders from Jingmen Hongtu who have worked hard to overcome various challenges. Dukum has a tropical desert climate; summer temperatures often exceed 40°C, with a temperature difference of 20°C between day and night. The dry air is frequently filled with sand and dust, and strong winds occur frequently, especially in the afternoons when sudden gusts can reach speeds of 15 meters per second. For the lifting of 10-ton spherical shell plates and precision welding operations, these represent significant threats and are also the key challenges in on-site construction. To overcome these challenges, the project team constructed prefabricated wind-resistant work sheds, and carried out specialized wind-proof reinforcement for the core assembly areas and those at high elevations ； Install multiple layers of wind barriers at the site, and reinforce key work areas locally ； Establish a real-time wind condition monitoring and early warning system, with dedicated personnel to monitor wind speed and direction. The person in charge of Jingmen Hongtu Company said that this is the first time the company has successfully applied advanced hydrogen storage technology to overseas hydrogen balloon tank projects, breaking the monopoly held by European and American companies in the high-end hydrogen energy equipment market in the Middle East.
