Digitalised Ex Maintenance

The Project

The existing partial Ex register was imported to the Dron & Dickson digital system which was then used to plan, conduct, report and close out inspection activities and to build the hazardous area verification dossier.

• All tasks were downloaded to handheld tablets where the inspections were recorded and uploaded back to the database for immediate analysis and creation of further actions.
• RFID tags were installed and associated at the time of inspection to aid future equipment identification.
• The new database facilitated live consistent data and intelligent reporting allowing immediate fact-based analysis and subsequent decision making.

The Result

Compared to a similar concurrent project where the client elected to take a ‘paper-based’ Ex inspection approach, several benefits were obtained:

• No ‘multiple handling’ of inspection records to transcribe from ‘site form’ to Excel
• Savings in labour resource cost for manual data handling
• Savings in data recording time during repeat or ongoing inspections

22 minutes per item of equipment were saved. At approximately 12,000 items inspected this equated to a saving of at least 600 man-days. Using an average day cost across the roles of Inspector, Data Inputter and Engineer, a total estimated saving of £180,000 was made by implementing the digitalised Ex maintenance system.
