Summary
A hyperbaric lifeboat’s aft lifting chain failed during transfer from davits to a crane for a reception-facility mating trial. Nobody was injured. External storage contributed to corrosion, while a protective cover concealed damage from inspection. Actions included destroying chain slings older than 12 months, below-deck storage and auditing third-party inspection compliance.
