At Lotte Chemical’s ethylene glycol plant in Louisiana, Mammoet overcame the project’s tight schedule and successfully executed the largest lift on the job.
Following severe weather delays, Mammoet lifted the 350-foot-long, 3.5-million-pound wash tower with the PTC 200 DS on Sept. 29. The head section was hoisted out of the saddle with the crane, and the rear section was simultaneously lifted out of the saddle with the help of 60 SPMT axle-lines with a tail frame. Once the wash tower was fully erected, the vessel traveled 442 feet to its foundation. The entire process took 3.5 hours.
With this lift complete, the PTC 200 DS will be reconfigured, and another 220 feet will be added to its reach. This brings its total reach to 713 feet, which is just under 2.5 times the height of the Statue of Liberty. The added reach will significantly contribute to project efficiency, as it allows the crane to remain in its current location while still being able to reach modules that are farther away.
