The Top Drive Safety Challenge
In top drive drilling systems, emergency shutoff requires:
-Millisecond response to well kicks during continuous drilling
-Redundant barriers for both drilling and connection phases
-Compatibility with top drive quill and saver sub configurations
Our IBOP system delivers:
✅ 150ms hydraulic closure (upper IBOP)
✅ Manual backup (lower IBOP) for absolute reliability
✅ Direct top drive integration without adapters
Dual-Valve Protection Architecture
