Offshore slurry pipe

Offshore slurry pipe

The Taharoa mine on the Waikato coast does not have a good deep-water harbour nearby. To get the concentrated ironsands to offshore ships, the sands are mixed with water and pumped as slurry through a pipe along the seabed. The pipe emerges at a buoy, to which the ships moor. The slurry is taken aboard, where the sand is separated from the water.
