Sempra Energy is eyeing a floating liquefaction solution to export shale gas-fed LNG from its Port Arthur facilities in Texas, writes Lucy Hine.

A 3 million to 3.5 million tonnes per annum barge-based FLNG unit could be moored alongside the three-plus miles of waterfront the company controls at its 2800-acre site on the US Gulf coast, sources said.

The FLNG unit is expected to cost in excess of $1 billion and could be in place from late 2015.

Sempra is believed to be keen to attract companies to own and operate the FLNG unit and market its capacity.

The site is said to be large enough to accommodate several floaters.
