Abstract
A method of removing drill cuttings from an oil and gas well drilling platform includes the steps of separating the drill cuttings from the well drilling fluid on the drilling platform so that the drilling fluids can be recycled into the well bore during drilling operations. The cuttings are then transmitted via gravity flow to a materials trough having an interior defined by sidewalls and a bottom portion. The drill cuttings are suctioned from the bottom portion of the trough interior with a pair of primary suction lines, each having an intake portion that is positioned at the materials trough bottom. Drill cuttings are transmitted via the primary suction lines at flow velocities in excess of 100 feet per second to a pair of collection tanks that each have an interior. A vacuum is formed in sequence within the interior of each tank using a blower that is in fluid communication with the tank interior via a vacuum tank and secondary suction lines.
