Abstract
An apparatus, system and method is disclosed for processing geological solids or wellbore cuttings generated by excavation or drilling under a body of water. An apparatus for processing solids in association with a riser may employ a solids processing apparatus having a central cavity that is substantially free of mechanical obstructions. The central cavity may be positioned in-line with the riser. The apparatus may be adapted for receiving solids within the central cavity and reducing the particle size of the solids by action of a cutter assembly which is positioned outside of the central cavity. The cut and processed solids may be pumped to the surface of the water.
