Summary
Investigation of a conductor drop during decommissioning at Mustang Island 85. Corrosion-related wall loss allowed stationary slips to lose grip, overloading the crane’s auxiliary line and dropping its headache ball onto an occupied work basket. No injuries or pollution occurred. Recovery used additional retention; recommendations address casing inspection and drop-risk mitigation.
