Freeport LNG Development LP has reported another outage of its third train, currently the only one not under extensive maintenance at its Texas terminal, days after production appeared to resume, according to pipeline data and regulatory filings.

The firm told Texas environmental regulators the unit experienced a system trip on Tuesday afternoon that lasted until midday Wednesday, requiring flaring. This time, the issue was ascribed to a problem with the main cryogenic heat exchanger.

“The plant operators managed the cooldown and restart of Train 3 as efficiently as possible to minimize flaring, as well,” Freeport staff said in a filing to the Texas Commission on Environmental Quality.
