Summary
An ROV and its tether management system were lost during launch following umbilical termination failure. Recovery caused further damage when sharp bullet edges cut a soft sling. The flash examines socket seating, curing and possible un-axial loading, and recommends revised termination procedures, checked bullet design and an emergency recovery strop.
