DC spike

thingiverse

To halt the flow, a heavy spike with a deformable collar is proposed. The weight equals the pressure multiplied by the area of the BOP orifice, and it's designed to fit within the stuck drill pipe. After insertion, the spike should be secured and a top kill collection device added for leak prevention. Remove as many drill pipes as necessary, then lower the spike, allowing the collar to deform against the BOP orifice for an effective seal.
