Our work in identifying the cause of this UPS failure and implementing a mitigation design process resulted in the prevention of further catastrophic downtime events for this large multinational biotechnology facility
This multinational biotechnology facility suffered a UPS failure. We were tasked with identifying the critical single points of failure within the electrical distribution system using both state enumeration statistical analysis and failure mode evaluation analysis. Design mitigation to avoid waste in product was also required by the client.
The problems we identified included:
"Regular power system studies (monitoring and modelling) coupled with failure mode evaluation analysis (FMEA) helped identify a critical weak point within the facilities electrical distribution system. Power system health checks gave early warning, which helped prevent potential downtime and financial loss of €2 million. Moving from fire fighting mode to a controlled position that prevents potential downtime allows for a more efficient, profitable and safer site."
By implementing the solutions the client avoided a catastrophic event when the mains supply to the cold store failed. Shift technicians were able to respond immediately to restore full power to the cold store in under an hour, preventing a waste in product estimated to be in the region of €2m. Expected savings when the mitigation and study costs are taken into account was €1.9m.
