Project Scope

As part of the Fortescue Eliwana mine, Partum was engaged in the design of the 33kV overhead distribution network interconnecting the following:
 

  • Mine Power Station.
  • Ore Production and Trade Load Out Facilities.
  • Telstra Radio Base Station.
  • Administration and Laboratories.

The project comprised of 4,500m of a phosphorus and cherry phase conductor along with a 144 core single mode OPGW conductor throughout the various areas of supply.

Challenges Overcome

  • Adverse terrain across the FMG Eliwana mine.
  • Numerous avoidance and heritage areas.
  • Undocumented flood plains.
  • Difficulty obtaining site information.
  • Change in the termination points at the power station and the train load out facility.
  • Multi-disciplines working in parallel site wide with an evolving mine master plan.

Solution

  • Effective two way and proactive communication with the client ensuring expectations met and exceeded.
  • Previous experience utilised in the realignment of the powerlines.
  • Additional foundation designed to minimise rock excavation.
  • PLS CADD modelling to achieve optimal span lengths given the adverse terrain and avoidance areas.
  • Complete preparation of the power and earthing system modelling as part of the HV submission deliverable.
