Presentation Title: The Development of Inspection, Testing and Maintenance Requirements for Dam Outlet Mechanical and Electrical Assets

Abstract: Mechanical and electrical assets play a vital role in the operations of dam outlet works, whether to supply customer and environmental water, passing of flood waters, or mitigation of dam safety emergencies. Typically, dam owners and operators recognise the importance of mechanical and electrical assets operating as designed when called upon, however the inspection and testing of these assets is often lacking.
There is limited guidance available to the industry regarding recommended mechanical and electrical assets testing extent and frequency. It is also often difficult, if not impossible, to conduct inspection and testing of these assets without the need for operation downtime.
Melbourne Water has a comprehensive inspection and condition assessment program for its transfer network and dam civil assets. However, headworks mechanical and electrical assets have typically not had an appropriate level of testing and inspection, given their functions and criticality.
The large number of mechanical and electrical assets across Melbourne Water’s portfolio of 16x dams meant it was not immediately possible to implement testing and inspection regimes for all assets, due to time and resource constraints. A staged approach was required to identify individual asset criticality; determine risk-based inspection, testing and maintenance priorities; and progressively develop schedules, testing requirements and work orders for implementation through FMMS.
