Summary
An ROV/TMS assembly fell to the seabed during a test-dive launch when its umbilical termination slipped through the socketing; nobody was harmed. Investigation identified inadequate cone size, uneven strand distribution, excessive docking force and resin-related shape changes. Corrective actions included a larger cone and adjustment of docking-head dampers.
