Root Cause Failure Analysis (RCFA) Software

Quickly Diagnose & Resolve Your Asset Risk with RCFA Software

RCFA is the leading methodology for determining what must be done to ensure that any negative deviation in performance for any asset or system will not happen again within tolerable levels of risk as defined in the organization’s asset management system. The decision logic within ACTOR assists Facilitators in selecting between formal and informal approaches, based on criticality. ACTOR allows the RCFA Facilitator to efficiently capture important information through building the cause and effect diagram, then drilling down until the root cause and the effective solution(s) have been identified.

Case study: Root Cause Failure Analysis of a Centrifuge Failure

On November 19, 2013, a Centrifuge experienced a catastrophic failure, throwing the pillow block bearing and the planetary gearbox from the unit and causing secondary damage to the structure and Rotary Drum Thickener.

The 750-lb. gearbox (10) on the unit came free and flew 30 feet in the air and damaged the 460v power rails for the bridge crane. The gear landed and spun like a top on the concrete and etched a design.   The bowl almost came out of the housing. It was kept in place by only four bolts that were still intact on the cover.

Fortunately, there were no injuries. But, due to the severity of the failure, the leadership of the wastewater organization initiated a Root Cause Failure Analysis (RCFA).
