Mammoet’s PTC reaches record heights

13 March 2018


Mammoet has successfully completed the heavy lifting activities at Lotte Chemical’s Mono-Ethylene Glycol project in Louisiana, USA.

After its opening, scheduled for 2019, the plant will be the largest of its kind, with a capacity to produce 700,000t of ethylene glycol per year. Mammoet was awarded the heavy lift portion of the project which included 62 scheduled lifts. By using its largest crane, the PTC 200 DS, and extending its reach to record breaking heights, Mammoet completed the scope two weeks ahead of schedule.

The lifts executed by Mammoet ranged from 30t to 1,600t. The largest of these was the wash tower, which is over 100m high. Following that lift the PTC 200 DS was reconfigured to include an additional 220ft (67m), bringing the total reach of the crane to 713ft (217m). This is the tallest the PTC has ever been on a job site. The configuration allowed the crane to remain in one location and execute lifts of modules located outside the original lifting radius, thus keeping lifting activities consistent and eliminating downtime associated with crane relocation.

Patrick van der Meide, vice president of sales and marketing at Mammoet USA, said: “With this project, we were able to demonstrate that the PTC’s value extends beyond lifting oversized and heavy objects. It was the ability of this crane to reach smaller modules and execute various lifts outside the original lifting range which ultimately delivered greater efficiency, enabling the scope to be completed safely and successfully ahead of schedule.”
