ABSTRACT:
This relates to drilling in water from a platform or vessel using a riser pipe. An inverted funnel skirt or cone is placed over slots cut in the wall of a riser pipe a short distance above its lower end. The apex end of the cone is welded to the riser pipe above the slots and drill cuttings pass through the slots and fall to the seafloor. Another embodiment includes an "L" shaped diverter flowline welded to the periphery of each hole in the riser pipe with one leg of the "L" extending a short distance below the hole.
