A prominent terminal owner is developing a premiere export facility that will increase their storage capacity by 8.5 million barrels with potential expansions to 10 million barrels. The terminal owner will connect crude oil pipelines to waterfront storage, providing a critical link in the Texas distribution chain for worldwide exports.

To accomplish this, the terminal owner awarded Tarsco a lump sum contract to construct 20 new API 650 crude oil tanks in a grassroots terminal in Ingleside, Texas. The project began in August of 2018 with engineering and included the engineering, procurement, fabrication, and construction including: deep soil improvement, foundation installation, tank erection with internal steel floating roofs, aluminum geodesic dome roofs, internal and external painting:

  • (20) 209’ dia. x 70’ high carbon steel tanks
  • Capacity each: 17,964,366 U.S. gallons (appx. 428,000 bbls)
  • Total capacity: 359,287,320 U.S. gallons (appx 8,560,000 million bbls)
  • Total steel tonnage: 25,000 U.S. tons of carbon steel
  • Steel thickness: 1.29” on first ring

The tank contractor was responsible for deep soil foundations, load transfer pad, ringwall foundations, interior and exterior coatings, tank erection and geodesic dome roof erection.

The contractor utilized a sister company to shop prime, burn, bevel, and roll the steel from its facility on the Gulf Coast before shipping to the project site. Another sister company was used to field blast and coat interiors and exteriors of the tanks. Lastly, the contractor self-installed all geodesic dome roofs with its own field forces. With these capabilities and flexibility, the contractor successfully completed the project from start of deep soil foundations to tanks in service in twenty months.
