- Ok Tedi, Papua New Guinea

-
The Ok Tedi mine is located in the highlands at the western end of Papua New Guinea. Copper concentrate from the Ok Tedi mine is loaded onto barges at Kiunga, on the Fly River, for transport down the Fly River to the coast. The loading wharf at Kiunga consists of a tied sheet pile wall. During the drought in the highlands of PNG in November 1997, a flash flood caused the loading wharf to collapse, preventing the loading of any product from the mine.
