Cockburn, Maintenance dredging

Shell sand for quicklime production

The client “Cockburn Cement Ltd.” produces quicklime at their cement plant at Munster in WA, a production which requires a continuous supply of shell sand, dredged from a specific area, offshore at Owen Anchorage, West Australia. The Trailing Suction Hopper Dredger “Modi R” is allocated to the project, supplying a monthly average of 130,000 m³ shell sand.

After loading Modi R precisely navigates close to the Woodman Point Jetty Reclaimer and dumps load next to the jetty for Cockburn Cement to reclaim the Shell Sand (2-10 minutes).
