What to Ask During Solids Dewatering, Transport, and Disposal Design (B-FSM-154)

I’ve listed some key questions that should be asked during design of any D-T-D system. These questions should be asked of your design team, operations group, and engineering contractor working on the Facilities Sand Management system. These questions will guide your decision-making process on the most appropriate process scheme to use.

  • Is the facility onshore or offshore?
  • Is the facility manned or un-manned?
  • If offshore, can the solids be disposed overboard?
  • Does the process system contain any hazardous components?
    • Gas: H2S, BTEX
    • Liquid: Mercury
    • Solid: NORM
  • Are solids, such as drill cuttings, already being handled at facility?
  • What is the level of automation required?
    • Fully automated systems can be designed, but with substantially increased cost
  • How will the solids be transported from the separation system to the disposal system?
  • What are similar facilities in your company or the geographic area doing?
