Summary
A taut-wire weight swung towards two divers and a subsea structure during recovery from a DP vessel, narrowly missing them. An unrelated acknowledgement was mistaken for permission to lift. The flash identifies communication failures and gaps in operational experience, recommending repeat-back protocols and review of personnel familiarisation.
