Summary
A vessel crane’s wire rope failed during offloading, dropping a 69-ton wind turbine nacelle 2.2 m onto the deck near personnel. Corrosion, wear and monotonic ductile overload were identified. The flash relays USCG recommendations on load testing, lubrication, maintenance tracking, earlier rope renewal, visual inspection and crane-operator training.
