Summary
An ROV tether management system lost an aluminium door subsea after both bottom latches failed. The investigation identified an omitted check for secondary retention. The flash recommends checking fixings and reviewing dive checklists; DROPS cone analysis judged damage to nearby subsea assets very unlikely.
