The Seahorse Pipeline is planned to be laid from Cushing, Oklahoma to connect to the St. James, Louisiana refining complex. The 30inch diameter crude oil pipeline will have the capacity to transport up to 800,000 barrels of crude oil per day from Cushing to the Louisiana Gulf Coast.

According to Tallgrass Energy, the Seahorse Pipeline will operate as a common grade batch system. Along with the company’s Pony Express Pipeline, the new pipeline will help domestic refiners and international markets get access to “clean” barrels from five different production basins.

On the other hand, the Plaquemines Liquids Terminal will be jointly developed with Drexel Hamilton Infrastructure Partners. The new liquids terminal is being structured as a Public-Private Partnership (P3) in concert with the Louisiana state-owned Plaquemines Port & Harbor Terminal District (PPHTD).

Expected to be fully operational in the second quarter of 2020, the Plaquemines Liquids Terminal will have a permitted storage capacity of up to 20 million barrels. The liquids terminal will have the ability to fully load and unload Post-Panamax vessels, each with a capacity of about 1 million barrels and barges on its multiple deep-water docks.

Tallgrass Energy expects to construct a separate offshore pipeline extension that would provide Plaquemines Liquids Terminal the added capability of loading Very Large Crude Carriers (VLCC) by the third quarter of 2021.

Tallgrass Energy president and CEO David G. Dehaemers Jr. said: “The Seahorse Pipeline and Plaquemines Liquids Terminal projects build on our strategy to provide diversity of supply and greater market optionality to our customers.

“These projects provide highly desired take-away capacity from Cushing to the St. James refining complex, providing interconnectivity to more than 2.5 million barrels per day of refining capacity and access to international markets.”

Tallgrass Energy said that the project investment will be subject to getting satisfactory customer interest and receipt of relevant state and federal permits, and other factors.

Earlier this year, the company announced a joint venture with Silver Creek Midstream to develop a new 128km long pipeline in the US to deliver crude oil from the Powder River Basin to Guernsey, Wyoming.
