Pipeline expansion to deliver gas to Sabine Pass LNG

LNG Industry,

Williams Partners plans to further expand the Transco pipeline capacity by 1.2 million dekatherm/d in order to deliver natural gas to the LNG export facility at Sabine Pass. The Sabine Pass LNG terminal will connect US natural gas supplies with global LNG markets.

Transco has signed an agreement with Sabine Pass Liquefaction L.C. as the anchor shipper, which provides a transportation contract quantity that is sufficient to proceed with execution of the expansion, known as the Gulf Trace project. A binding open season to gauge additional market interest in the expansion is scheduled to conclude on 8 May 2014.


"Gulf Trace is a pivotal project at an extremely important time for Transco and the US natural gas industry as a whole. Gulf Trace is designed to ensure we continue to serve our existing customers who rely on natural gas from the Gulf Coast, while adding a very large, long-term market commitment in an area of Transco's system that is seeing decreased utilisation due to changing gas supply patterns in the United States," commented Rory Miller, senior vice president of Williams Partners' Atlantic-Gulf operating area.

Sabine Pass LNG

The Sabine Pass LNG export facilities are currently under construction and scheduled to be completed in phases starting as early as Q4 2015. Once complete, the Sabine Pass LNG terminal will be the first large-scale LNG export facility in operation in the United States. Sabine Pass Liquefaction's project is supported by long-term contacts with several LNG off-take shippers and is expected to provide LNG for export to diverse markets overseas.

Gulf Trace expansion

The Gulf Trace project will make Transco's production area mainline and southwest Louisiana lateral systems bi-directional from Station 65 in St. Helena Parish to Cameron Parish, in Louisiana. In addition to the pipeline reversal, a new, 8 mile, 36 in. lateral pipeline and two new compressor stations are planned in order to provide firm transportation service to the Sabine Pass LNG facility.

The estimated project cost for Gulf Trace is approximately US$ 300 million and the target in-service date is early 2017, subject to timely receipt of all necessary or required approvals by regulatory bodies, including the Federal Energy Regulatory Commission (FERC).
