O’Donnell Consulting Engineers investigated the cause of an accident due to a failed threaded closure on a wellhead. Through metallurgical evaluations, material testing, and engineering analysis, it was determined that the cast iron nut had failed due to fatigue. Design modifications were then recommended.
