Plaquemines LNG Raises The Roof
Venture Global LNG has announced the successful raising of the roof of the second liquefied natural gas (LNG) storage tank at the Plaquemines LNG export facility in Plaquemines Parish, Louisiana. It comes seven weeks after the roof raising of tank one, which was completed in February.
Each roof weighs 900 tons (816 tonnes) and is 294 ft. (89 m) in diameter. Air raising allowed each roof to be erected concurrently with the shell. The tank domes were using 0.3 psi (0.02 bar) of pressure underneath the roof. They were raised from ground level to a top-of-the-wall height of 130 ft. (39 m). Eventually, the tanks will have an inner tank made from 9% nickel alloy and outer wall and outer roof made from concrete to provide full containment of the LNG and provide the maximum level of resilience and safety.
“Today represents another major milestone in the construction of Plaquemines LNG, with both roofs now raised for the tanks serving Phase One,” said Mike Sabel, CEO of Venture Global LNG. “With Phase One deep into construction and our recent final investment decision and full notice to proceed on Phase Two, Plaquemines is well positioned to be the next new major LNG capacity to reach the global market.”
A total of four tanks are planned Plaquemines LNG. When operational, it will be capable of storing 7.06 MMscf (200,000 m3) of LNG.
