The dry bulk materials, such as cement, barite, bentonite, dry mud, fly ash or any many more, are stored in pressure tanks (P-tanks) until they are used for the drilling operations.
On drilling rig a dust control system insures a dust free work environment for the rig's crew and complies with stringent environmental regulations. The dust control system recovers dry bulk materials so they can be recovered for use and result in interesting cost savings.
The control system for loading a new shipment from a supply vessel, transferring materials from one P-Tank to an other or to the mixing equipment requires an intimate knowledge of the working of all system components that HW Carlsen has.
