Thermal–Structural Coupling Analysis of Subsea Connector Sealing Contact

Taking a subsea collet connector as an example, the contact characteristics of sealing structure under thermal–structural coupling were studied. Considering heat transfer problem in deep water, model seawater layer between structures was established, and relationship equivalent thermal conductivity, composite coefficient, temperature determined. The steady-state field distribution action internal high-temperature oil gas external low-temperature obtained. stress deformation load, analysis theoretical numerical simulation key compared verified. Analysis coupled calculation, for field, carried out on connector. At same time, pressure shock mode steady analyzed, which showed that lenticular gasket is sensitive to high conditions.
