AI Technical Summary
Existing deepwater production riser systems suffer from poor reliability of electric heating systems, severe electromagnetic interference, delayed annular leakage monitoring, and a high risk of seawater intrusion, which affect system safety and service life.
The deep-water production riser system adopts a multi-layer composite structure, integrating electric heating, distributed fiber optic temperature monitoring, and annular space visualization monitoring. Through an internal closed heating circuit and multiple electrical protection designs, it achieves stable operation of electric heating and real-time visualization monitoring of the annular space status.
It improves the operational safety and service life of deepwater production riser systems in extreme environments, reduces electromagnetic interference and corrosion risks, achieves efficient heating and early leak detection, and supports convenient maintenance.
