Port Arthur LNG Facility, Texas, United States of America

Port Arthur LNG

Sempra LNG & Midstream, through its affiliate Port Arthur LNG, plans to develop a new natural gas liquefaction and export terminal in Port Arthur. The proposed facility will include natural gas liquefaction trains, LNG storage tanks, marine facilities for LNG ship berthing and loading, natural gas liquids and refrigerant storage, feed-gas treatment facilities, and truck loading and unloading areas.

The project received approval from the Department of Energy (DOE) to export domestically produced gas to the Free Trade Agreement (FTA) partner countries of the US, in August 2015.

Sempra LNG & Midstream and Woodside Petroleum signed a project development agreement for the proposed Port Arthur LNG facility, in February 2016.

Port Arthur LNG initiated the pre-filing process with FERC in March 2015 and plans to fill a final FERC application in 2016.

Construction on the facility is expected to begin by early-2017 and the new liquefaction and export terminal will become fully-operational by 2021.

Port Arthur LNG terminal location

The project site is located approximately 86.9mi (140km) east of Houston and will utilise approximately 2,900 acres of Sempra's land area including 3mi (4.8km)-long waterfront area along the Sabine-Neches Ship Channel and 1.25m (2km) of waterfront on the Intracoastal Waterway.

The project will also occupy a 3mi (4.8km) portion of Highway 87 between Keith Lake Pass and Intracoastal Waterway.

Project details

The proposed liquefaction and export facility will contain feed gas pre-treatment facilities, two 4.5 million tonne per annum (Mtpa) capacity natural gas liquefaction trains, two 160,000m³ LNG storage tanks, condensate product storage, and combustion turbine generators for captive electricity generation.

"The new facility will improve the access to competitively priced natural gas to meet increased needs for natural gas."

The natural gas liquefaction trains will have a total export capacity of 9.07Mtpa or 517 billion cubic feet a year (bcf/year).

Port Arthur pipeline, a subsidiary of Port Arthur LNG, is planning to construct, own and operate new natural gas pipelines, which will connect the Port Arthur LNG facility to multiple interstate and intrastate pipelines. The pipeline interconnections will connect the Port Arthur LNG facility to major natural gas supply basins.

The facility will also include relocation and upgradation of a portion between Intracoastal Waterway and Keith Lake Pass along the Highway 87, to accommodate the construction of the marine terminal berth for berthing and loading of LNG vessels.

Port Arthur LNG facility benefits

The proposed project is expected to create approximately 3,000 construction jobs during construction phase, along with 100 full time jobs during the operation and maintenance of the LNG terminal.

The new facility will improve the access to competitively priced natural gas to meet increased needs for natural gas. It will also support manufacturing, small business and local community and generate new revenue to the US economy.

The project development is expected to improve the nearby degraded wetlands, whereas the relocation of highway 87 will reduce the risks of erosion and flooding and deliver safer route for evacuation of Sabine Pass residents.
