Abstract: Rapid evacuation and deployment of dry materials is achieved by the dual structure of this device and the method of using it to fill and empty vacuum reloading tanks automatically. This permits materials such a bentonite, barite or cement to be handled easily and without dust on a rig floor and mixed appropriately as needed for well control and completion operations. Dry bulk material is offloaded from an offshore supply vessel into atmospheric tanks, which provide fluidized bed systems to aerate and agitate and move material through piping into the vacuum re-loader tanks. The dual re-loader tank system allows one tank to be emptied while another fills thereby providing sufficient flexibility to expertly manage receiving, storage, transfer, filtration and control of the bulk material on various space-critical platforms, including offshore rigs and service vessels, that require the handling of dry bulk materials in an accurate and dust-free manner.
