For the FEED, we performed preliminary design and construction bid evaluation and an engineer‑procure‑construct (EPC) lump sum price for the scope of the project, which included two CO2 pipelines and three metering and regulation (M&R) stations. This work was necessary for the utility to proceed with permitting of the project as well as deciding on the next phase of the project development.
The preliminary design included:
- CO2 dispersion study.
- Materials selection and fracture mitigation.
- Mechanical, civil and electrical design for the pipelines and facilities.
- Route selection and constructability evaluation for two 16-inch CO2 pipelines extending approximately 6 miles.
- One M&R station at the plant’s CCS facility and two M&R stations at the injection well pads.
The pipeline routes included horizontal directional drilling crossing and road boring, as well as additional design and safety considerations due to the pipeline route traversing a coal mining area. Additionally, we prepared cost estimates by obtaining quotes for materials, equipment and construction services, and coordinated with other contractors involved in the CCS project.
