Step 5: Solids Transport to Disposal - Overview (B-FSM-163)

The final sand disposal site determines transport method.

As slurry in piping

  • To caisson for overboard discharge or to pump for slurry fracture injection
  • Design piping layout and flow for proper and efficient transport (FSM-M1)
  • Distance may be 3-100 meters

As dewatered sand in bin/bag

  • To crane, fork truck, skip, ship, or transport vehicle
  • Lifting requirements from 1-3 metric tons
  • Allow room for bin/bag change-out

Typically batch transport – even as slurry

  • Match timing with transport of other solids/waste such as from drilling
  • Match timing for ship-to-shore so some storage may be required
