OSD’s Role

  • Project Management
  • Conceptual Design
  • Constructability Review
  • Cost Estimate

Summary

Extending the mine life beyond the current planned closure date of 2025 would mean ongoing handling and storage of tailings from the mill process was required. An option is a 125km tailings pipeline running from the mill at the Ok Tedi Mine Site to an expanded tailings storage facility at Bige. This would satisfy environmental standards and obligations.

To help evaluate the pipeline option, OSD conducted a conceptual study into the design and construction of the proposed tailings pipeline. This comprised of a constructability review, a concept level design and a cost estimate including hydraulic and sensitivity analysis to varying flow rates.

We are very pleased with the work that has been completed by OSD and should we elect to move forward after FID with FEED and so-on, OSD have placed themselves very well to continue with the project
