U.S. says Cheniere must do work on Louisiana Sabine LNG storage tanks
U.S. energy and safety regulators told Cheniere Energy Inc the company had to take several steps before the agencies would authorize the return to service of two liquefied natural gas (LNG) storage tanks that leaked at the Sabine Pass LNG export terminal in Louisiana.
The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Federal Energy Regulatory Commission (FERC) told Cheniere that neither agency is prepared to authorize a return to service at this time.
In April 2018, Cheniere agreed to take certain corrective measures, but the agencies said in their filing that the company has in some instances “failed to comply” with requests to test equipment and provide documentation of the testing.
In response, Cheniere, the biggest U.S. LNG exporter, said in an email, “We are analyzing the letter from the agencies and will provide a formal response. We have been responsive and forthcoming throughout this process, and will continue to be.”
PHMSA ordered Cheniere to shut two LNG storage tanks on Feb. 8, 2018, after plant workers on Jan. 22, 2018, discovered a 1-to-6-foot-long crack at one tank that leaked fuel into an outer layer. During the investigation of the Sabine site, PHMSA discovered a second tank had also experienced releases of LNG from the inner tank.
The agencies told Cheniere that any work done to return a tank to service prior to completion of the agencies’ requirements is “at your own risk.”
The agencies noted PHMSA has previously conveyed its concern to Cheniere regarding premature filling of one tank with perlite, which is used to insulate LNG tanks.
Some of the tasks the agencies said Cheniere would have to complete before allowing the tanks to return to service include a structural re-inspection of all LNG storage tanks at Sabine and installation of additional devices to detect leaks.
There are five tanks at Sabine, each with the capacity to hold the equivalent of 3.4 billion cubic feet of gas (bcf), or 17 bcf in total. One billion cubic feet of gas is enough to fuel about 5 million U.S. homes for a day.
Sabine Pass was the first big LNG export terminal to enter service in the Lower 48 U.S. states in February 2016. There are now four LNG export terminals operating in the United States with a total capacity of 6.4 billion cubic feet per day.

The continued expansion of natural gas trade is led primarily by growth in the LNG sector, which has tripled over the past 3 yr.
Industry Focus: The future of gas-to-power projects in Africa
Natural gas is expected to play a central role in supporting Africa’s drive to achieve electricity connection for nearly 600 MM people without access to the grid, to reduce widespread reliance on coal for power generation, and to fast-track the continent’s slowed industrial expansion.
Regional Focus: Gazprom faces challenges for combined LNG/processing plant in Baltics
Russia’s largest natural gas producer, Gazprom, aims to build a giant project on the Russian Baltic seaport of Ust-Luga. The plans include the construction of a combined LNG and gas processing plant.
Environmental Considerations for Gas Pipeline Construction in Sensitive Areas
Ambioconsult, a subsidiary of Vepica, developed an environmental and social impact assessment for a subsea/land gas pipeline in Venezuela. This webcast will provide details on how the project lessened environmental impact and complied with regulations and stringent conditions, such as the presence of national parks and endangered species. The presenters will provide the steps they used to achieve social and environmental sustainability in a capital-intensive natural gas pipeline project.
