Abstract：The deepwater subsea manifold with control module is one of the key equipment that restrict China's independent development of deepwater oil and gas resources in the South China Sea. To accelerate the process of domestic development and production of the deepwater subsea manifold with control module, this paper analyzes the significance, system components and the requirements of their domestic development and production, as well as the achievements made at present stage. It describes the engineering design, manufacturing, testing, and installation technologies, along with the independent development of engineering products. China has made breakthroughs in key technologies, developing the country's first 500-meter water depth category subsea manifold with control module, which has been applied in a gas field development project. At the same time, significant progress has been made in the development of compact subsea manifold and baseplate subsea manifold. Finally, this paper provides an outlook on the domestic development and production; and application of the new types of subsea manifold with control module.
