During diving operations, a recovered port taut wire parted while being slewed inboard, dropping its 315 kg clump weight clear of divers and subsea assets. A worn, sharp-edged wire guide had damaged the wire. The flash discusses dropped-object cones, ROV checks of landing locations, repairs and review of inspection routines.
