Shanghai 200030 China ） Abstract: To promote localization process of subsea spherical flange in China, an intensive study on subsea spherical flange, which is full of technical difficulties and high risks, has been conducted in this paper. Firstly, a brief introduction to the characteristics of subsea spherical flange has been given, and then the development situations of subsea spherical flange in domestic and foreign coun- tries are compared. Finally, based on the research and development results by the well-known offshore oil domestic subsea spherical flange supplier, combined with the key design parameters of subsea spherical flange which will be used in one project in the East Chi- na Sea, a serials of subsea spherical flange manufacturing and follow-up overall system testing have been done. It is concluded that the subsea spherical flange is suitable in subsea application, which lay the technical basis for future application o
