Summary
A diver replacing a wreck marker in the Dover Strait had his umbilical entangled in Norma’s rotating propeller. He switched to bottled air, cut himself free after the propeller stopped and escaped uninjured. The investigation identified shortcomings in propulsion familiarisation, diving procedures, shipboard communication and safety management audits.
