With over 15 years of expertise in subsea interconnect technology, I lead HYSF's R&D team in designing high-pressure (60MPa) solutions. My focus is on ensuring zero-leakage reliability for ROVs, AUVs, and offshore instrumentation. I personally oversee the validation of our custom connector prototypes.
