Design of the Metal Gasket of Subsea Connector for Manifolds

The subsea connector for manifolds is working in bad conditions. The water environment is harsh. And the inner pressure of the jumper which is connected by the subsea connector is high. In this paper, a new design of metal gasket for the connector is proposed. The metal gasket develops a surface contact with the upper and lower hubs. Under the effect of internal pressure, the seal ring will expand outward to ensure good seal performance. The design has a simple structure, and is easy to manufacture and disassemble .This paper uses the finite element analysis to investigate the gasket’s performance in different working conditions, and provides reference for real tests and the engineering application.
