At Hinkley Point C, Mammoet handled the transport and installation of the most sensitive components of the nuclear power plant, including the reactor and steam generators, weighing up to 520 tons each.
To pass through a narrow opening and confined space, the team designedthe Outside Lifting System (OLS). This system combines winches, jacks, and rails bent at 30° to move and orient components with precision. Inside, two Temporary Lifting Devices (TLDs) were used to move the components from a horizontal to a vertical position: the main TLD, with a capacity of 600 tons, used a containerized winch, while the second, with a capacity of 320 tons, relied on cable jacks for the final reorientation.
This tailor-made solution, independent of existing lifting equipment, enabled safe and controlled transport while reducing noise and power consumption on site. Mammoet's experience in nuclear engineering, already applied at Flamanville and Bruce Power, was confirmed in this complex operation.
