Mammoet has completed a major milestone with the installation of the main cryogenic heat exchanger (MCHE), considered to be the heart of train one, at a liquefaction project along the US Gulf Coast.
The lift of the MCHE, which weighed a total of 650,000 pounds (295 tonnes), was a dual lift using a Terex-Demag CC-2800 crawler crane as the main crane and a Liebherr LR-1300sx crawler crane on the tail. The inclement weather was challenging and meant broadening the travel path for transport, smoothing the roads, and re-doing the crane pads and travel path after storms had moved through.
The project is currently comprises three natural gas liquefaction trains with approved liquefied natural gas (LNG) export capacity of 1.7 billion cubic feet per day. When complete, it will be one of the largest LNG export terminals in the US.
Randall Fox, Mammoet USA senior project manager, said, “The combined efforts and hard work of all crews on site made this a safe and successful installation. The crews displayed an ‘adapt and overcome’ mentality to many obstacles to execute this operation in a truly professional fashion.”
