Summary
An ROV and its TMS fell to the seabed during recovery after an umbilical termination detached. Examination identified poor termination workmanship and defects, alongside inadequate subcontractor skill and quality verification. Revised procedures require photographic evidence of assembly steps, with quality surveillance recommended for subcontractors. No personnel were injured.
