The Gulf Connector Expansion Project has been placed into full service. The Williams project is a 475,000 dekatherm per day expansion of the Transco pipeline system in Texas and Louisiana, USA, providing service to Cheniere Energy’s Corpus Christi liquefaction terminal and Freeport LNG Development’s liquefaction project.

Train one of Cheniere Energy’s Corpus Christi liquefaction terminal began commissioning in August 2018 with completion estimated in Q1 2019. The first three trains, in commissioning and under construction, will have a liquefaction capacity of 13.5 million tons per annum (mtpa). Train one of Freeport LNG export terminal is expected to enter commercial operation in Q3 2019. The Freeport facility has three liquefaction trains under construction with an export capacity of over 15 mtpa.

The project includes three new compressor stations.

Station 17 is a new compressor station in San Patricio County, Texas, USA, that utilizes One Solar Taurus 60 unit with a C40 compressor for a total of 7800 hp (5818 kW).

Station 23 is a new compressor station located in Victoria County, Texas. It includes two Solar Taurus 70 units with C40 compressors (10,800 hp [8056 kW] each) for a total of 21,600 hp (16,113 kW).

Station 32 is a new compressor station located in Wharton County, Texas, that utilizes one electric motor drive unit with an Ariel JGH/4 compressor for a total of 1250 hp (932 kW).

“Since 2017, Williams has now added more than two billion cubic feet per day of capacity to directly serve global LNG export facilities,” said Alan Armstrong, president and chief executive officer of Williams. “Projects like Gulf Connector, which leverage existing gas pipeline infrastructure, make it possible to connect abundant domestic supply with emerging international markets, giving a boost to the U.S. economy while helping meet the world’s increasing demand for clean energy.”

The Gulf Connector Expansion Project is Williams’ second project designed to serve US Gulf Coast LNG terminals. In February 2017, Williams placed into service its Gulf Trace Project, providing 1.2 Bcfd (33 x 106 m3/d) to Cheniere Energy’s Sabine Pass Liquefaction project in Cameron Parish, Louisiana, USA.
