Summary
During berthing, excessively slackened mooring ropes fouled a turning propeller, became taut and parted. Near-vertical recoil missed crew standing in the snapback zone. The flash identifies communication, awareness and supervision shortcomings, and records preventive actions involving risk assessment, briefings, crew retraining and ship-specific constraints.
