Summary
An alert describes annular flow after surface casing cementing. Using the diverter in test mode to retain pressure led to leaking riser seals and disabled remote control, followed by evacuation. Recommendations address contingency planning, pressure monitoring and diversion, communication, rig-specific supervisory training and review of shallow casing cementing practices.
