Sempra Energy has hired a Foster Wheeler subsidiary to do the engineering for a proposed liquefied natural gas export facility in Hackberry, according to a news release.

The proposed LNG plant will have a capacity of 12 million tons per year.

Foster Wheeler did not disclose the contract’s value. The global engineering firm has designed other LNG facilities.

The Sempra facility, if it wins federal regulatory approval, would be the second large-scale LNG export facility built in Cameron Parish. It would also be the second in Louisiana and the United States.

Earlier this month, the Federal Energy Regulatory Commission gave Cheniere Energy the go-ahead to begin building an LNG export facility in Cameron Parish. The facility could export up to 16 million tons of LNG a year, and its total cost has been estimated in the $10 billion range.
