Mammoet has completed the transportation, lift and final positioning of two feedwater preheaters within the Turbine Building of the Embalse Nuclear Power Plant.
This was the final installation for the Embalse Nuclear Power Plant Life Extension Project, in Argentina. Each preheater weighed 26t and measured 10.2m long, 2.3m wide, and 2.8m high.
Mammoet transported the pieces and lifted them using strand jacks and a climbing jacking system. Mammoet also moved the pieces by skidding them using skid beams and performed rotational skidding by using turntables. To support the preheaters during transport, Mammoet designed and fabricated temporary auxiliary saddles.
One of the biggest challenges Mammoet faced was working in a very confined space inside the turbine building. This meant that the assembly and measurements had to be accurate.
One of the biggest challenges Mammoet faced was working in a very confined space inside the turbine building.
This meant that the assembly and measurements had to be accurate.
Mammoet worked to tolerances of just 100mm for the rotation and 10mm in the straight corridor. When negotiating the curve, a detailed swept path analysis was required to ensure precision and safe completion.
Mammoet’s scope took place over three months, completing the final lift in just four hours and the overall project within the timeframe.
