Summary
An ROV survey discovered a subsea paraffin-inhibitor leak from a hydraulic flying lead in the Gulf of Mexico. Outer-jacket damage compromised collapse resistance; loss of positive pressure resulted in collapse and tearing. BSEE recommends considering pressure-maintaining procedures, training, check valves, low-pressure alarms, inventory monitoring and regular ROV inspections.
