Summary
An ROV fell to the seabed after recovery-system latching problems and umbilical separation. Cold, dirty grease slowed the latch, while the operator could not see the locked-position indicator. The flash identifies maintenance, procedure and supervision shortcomings and describes cleaning, functional verification and renewed procedural assurance.
