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?
