Williams Partners LP executed long-term contracts with two shippers for Gulf Connector, an expansion of the Transco Pipeline system connecting domestic natural gas supplies with global LNG markets, the company said Feb. 10. Transco is a wholly owned Williams Partners subsidiary.

Gulf Connector will deliver 475,000 dekatherms per day of gas for Cheniere Energy Inc.’s LNG Corpus Christi liquefaction project near Corpus Christi, Texas, and for a shipper in Freeport LNG Development LP’s liquefaction project near Freeport, Texas.

Both liquefaction facilities are currently under construction. The contracts are pending regulatory approvals.

The flow of gas will be bidirectional on a portion of the Transco system between Transco’s Station 65 in St. Helena Parish, La., to mainline interconnects with proposed header pipelines in Wharton County, Texas, and San Patricio County, Texas.

Cheniere’s Corpus Christi export terminal will have five liquefaction trains, the first two of which are scheduled to be operational in late 2018 and mid-2019, respectively.

The Freeport LNG export terminal will have three liquefaction trains and will begin operations in phases between September 2018 and August 2019.

Williams also said it is building the Gulf Trace project to serve Cheniere’s Sabine Pass liquefaction project in Cameron Parish, La., The first shipment of LNG from that facility is expected in late February or March, and Gulf Trace is scheduled to be completed in early 2017.

Gulf Connector and Gulf Trace are included in Williams Partners’ 2016 growth capital funding plan.

Williams Partners LP is based in Tulsa, Okla.
