Metallurgical failure analysis was requested for a failed piece of oilfield wire rope. Macro and microscopic examination showed the wire rope failed as a result of metal fatigue. Evidence also existed of abrasive wire rope damage and lack of wire rope lubrication.

Photograph B Failed wire rope wires show extreme wear, flat fracture and stepped fracture indicating metal fatigue.
As a result of the metallurgical failure analysis,it was determined that inadequate lubrication and improper usage by the operator of the equipment was the causes of the wire rope failure.
