Hacksaw Crude Oil Terminal

Fast-track EPC services for expansion of crude oil terminal handling and storage capacity

Hacksaw Crude Oil Terminal
Tilden, Texas
Client: EVX Midstream Partners LLC (EVX)

Project Highlights:

  • Storage capacity expanded from 20,000 barrels per day (bpd) to 40,000 bpd.
  • Well-coordinated engineering, procurement, and construction (EPC) efforts enabled first flow to be achieved within six months from project award.

Project Description:

Sargent & Lundy EVX Hacksaw 1920x1080_1

EVX approached Sargent & Lundy to perform a fast-track EPC project at the Hacksaw crude oil terminal based on our reputation for agility and quality. The overall goal was to expand the facility’s crude oil handling and storage capacity from 20,000 bpd to 40,000 bpd. Our turnkey services from concept through commissioning encompassed engineering, design, procurement, construction, and installation of the 40,000-bpd crude oil storage facility. The facility also included seven remote lease automatic custody transfer (LACT) metering sites for taking receipt, storing, and transferring collected crude to the terminal.

Project Scope:

Sargent & Lundy provided the following services:

  • Created the gathering facility process flow diagram (PFD), site layout, equipment location plan, piping and instrumentation diagrams (P&IDs), equipment list, instrument list, electrical load list, 3D CAD model, isometric piping drawings, and site layouts for remote LACT meter skids.
  • Designed the storage facility piping from inlet LACT metering to tanks and out of the station via a booster pump and discharge LACT meters.
  • Provided tank and skid foundation support, including design of tank foundations and location of helical piles for skid and pipe supports at the gathering facility and remote LACT metering sites.
  • Constructed three 36-foot-diameter (D) by 34-foot-high (H) 5,000-barrel (bbl) American Petroleum Institute (API) 650 steel oil tanks; one 25‑foot-D by 23-foot-H 1,000‑bbl API 650 steel slop oil tank; and one 15‑foot by six‑inch D by 25‑foot‑H 750‑bbl API 12P fiberglass water tank.
  • Installed one inlet LACT meter skid with a design flow rate of up to 40,000 barrel per day (bpd) with room to install an additional identical LACT meter skid in the future.
  • Installed two station discharge LACT meter skids with combined design flow rate of up to 40,000 bpd with room to install an additional identical LACT meter skid in the future.
  • Performed hydraulic calculations to identify booster and bottoms pumps that were required for the operating conditions; installed one booster pump with 40,000-bpd capacity.
  • Calculated flow rate required to empty slop oil and water tanks in a reasonable time and performed hydraulic calculations to determine bottoms pumps operating conditions.
  • Installed one slop oil tank bottoms pump and one water tank bottoms pump.
  • Constructed station piping based on 3D CAD model and Isometric drawings.
  • Interfaced with Chesapeake Energy to coordinate the installation of seven remote LACT metering skids on existing Chesapeake Energy-owned facilities.
  • Coordinated with the vendor to design the storage facility and remote LACT meter skids with connections in necessary locations based on the site layout.
  • Performed a study to assess whether National Association of Corrosion Engineers (NACE) International materials were required based on oil hydrogen sulfide (H2S) content in the crude oil. (The study found the H2S concentration was below the NACE threshold.)
  • Provided onsite construction and on-call engineering and procurement support.

Schedule Milestones:

  • Project Start: January 2018
  • Project Completion: May 2018


  • 2018 Engineering Excellence Award - American Council of Engineering Companies (ACEC).
