Abstract: In this paper, the significance and method of subsea connector sealing ring collision analysis was introduced. Based on explicit algorithm and finite element theory, the analysis and calculation method of the subsea connector sealing ring collision critical velocity was researched. In the process of analysis, the 3D model establishment, material properties set, meshing, boundary conditions set and collision parameters set were introduced. The calculated results were analyzed in detail, and the critical velocity was obtained, the necessary theory basis for clamp subsea connector connection velocity selection was provided.

Key words: subsea connector, explicit algorithm, finite element, collision, seal ring
