Summary
BSEE investigates a satellite umbilical termination failure affecting the MC 208/209 subsea well. Hydraulic lines ruptured, while fail-safe shutdown successfully shut in associated wells. Findings identify excessive loading on the connection plate and failure of temporary buoyancy rigging retained for long-term use. ROV inspection and recovered-component examination informed the investigation.
