Rohr-Idreco has designed, built, and installed an RISD400-M (16″) electric dredger for the North American frac sand mining operations.
This new dredger has a digging depth of 82 ft. (25m) and production capacity in excess of 800 tph.
The dredger is equipped with a state-of-the-art GPS and sonar system that provides the operator virtually real time mapping, showing where material has been dredged and where virgin material still lies through an intricate software system developed by Rohr-Idreco.
The dredger is also equipped with an RIDP 400 Rohr-Idreco dredge pump, plus five on shore RIBS 400 Rohr-Idreco booster pump stations.
These are some of the most efficient and modern pumps currently available in the market. They are designed for reduced wear and lower energy consumption. There were lengthy discussions with the customer to make sure that the dredger and booster pumps would meet the production as well as environmental requirements of the project.
Total delivery time was 7 months from contract signing.
