Summary
An ROV became trapped in a platform jacket during routine inspection in strong tidal current. Tether damage interrupted power and telemetry; subsequent recovery failed and the vehicle was lost. The flash identifies inadequate recovery procedures, understaffing and premature beacon battery exhaustion, and records procedural revisions and a current display added to the pilot interface.
