Mammoet has completed a four-year project setting almost 400 modules for energy and chemical company Sasol’s ethane cracker and derivatives project in Lake Charles, Louisiana, USA.

At the height of the project, Mammoet had almost 30 cranes and 450 SPMT axle lines of on site, supported by approximately 100 people divided between day and night shifts. Key lifts from the project were of an 800 tonne wash tower and a 1,523 tonne reactor that was set utilising Mammoet’s MSG 80 crane.

During the project, Mammoet utilised its adjustable modular lifting frame (AMLF) in order to save time. The AMLF is remotely operated and has a capacity up to 160 tonnes. Its sling length and position can be adjusted for different loads without having to lower and reconfigure the frame. Mammoet claims this allowed the team to maximise efficiency and set up to five modules in one day instead of only one per day.

“Mammoet’s close relationship and coordination with Fluor Technip Integrated (FTI) and Sasol directly enabled us to provide safe and efficient operations,” said Mammoet’s Gulf Coast general manager, Gerrit van Doornik. “Mammoet’s dedication to safety did not go unnoticed; our teams on site were awarded Sasol’s ‘Safe Crew of the Week’ award a total of eight times. Mammoet has proven to the industry that modular construction is a viable and efficient way of constructing plants and this project will go into Mammoet history as a proud achievement. This work would not have been possible without the diligence and tireless efforts of the entire team, inclusive of the support and trust from FTI and Sasol.”
