Cheniere to go mid-scale at Corpus Christi plant

US liquefaction player plans to replace two-train expansion with seven smaller modules

Cheniere Energy has replaced its plan for a two-train expansion at the Corpus Christi liquefied natural gas project with a design using seven mid-scale liquefaction modules, according to a regulatory filing.

The new design would slightly increase the facility's overall from 9 million tonnes per annum (mtpa) to 9.5 mtpa. It would also require electric instead of compressor engines for the proposed compressor station.

The proposed expansion project would build on the current development, where two trains are currently under construction while a third is awaiting a final investment decision. First LNG is expected in 2019.

Cheniere debuted the design in a November 2016 earnings call but revealed few details, such as site location. At the time, Cheniere said it had completed a competitive bidding process and awarded a front-end engineering and design (FEED) contract to a consortium consisting of KBR, Siemens, and Chart Industries.

The company told regulators on 4 October that the new design would result in no changes to the project's footprint or pipeline route, according to notes from a conference call posted by the US Federal Energy Regulatory Commission. The call was also attended by officials from the US Energy Department and the US Environmental Protection Agency.

Cheniere said it would send the agencies a letter identifying the proposed changes and providing an update on the Corpus Christi LNG the project in the following two weeks.
