Philip Vincent, Asset Engineer - Clem Jones Tunnel, Brisbane Motorway Services, Leighton Contractors (QLD)
At the CLEM7 tunnel we use Maximo to help us manage maintenance and record the condition of assets.
By accumulating quality data relating to work done, resources used (time, materials and services) most organisations gain part of the data needed to manage the lifecycle costs of their assets.
Performance data to go with this information is usually hard won – inspection reports, manual entry of readings from portable measuring equipment or, if you are really an occasional data file that can be uploaded.
This was the case at the CLEM7 until 2 years ago, when we negotiated read-only access to the data structures that lay behind our control system. This has allowed us to mine the vast expanses of data for average sump levels, air quality readings, bearing and winding temperatures, etc. and present the analysed results directly in graphical format or, in the case of machine run times we capture the values and post them directly to Maximo.
While trend graphs are very useful for confirming performance levels (we calculate flow rates in rising mains, detecting problems with pumps or check valves), accumulating data in Maximo makes maintenance cost-performance analysis that much easier.
