Sarens Collaborates on Hinkley Point C Nuclear Power Station Lift
Successful operation relied on smooth coordination between Sarens, Tissot, Bylor, and NNB.

March 2022

Executing big projects means coming together to collaborate with others on complex and demanding lifts. Recently, Sarens partnered with other contractors at the Hinkley Point C nuclear power station site, working closely with Tissot, Bylor, and NNB. The Hinkley Point C construction project is Britain’s biggest actions on climate change. Once completed, the power station will be key in helping the UK achieve net zero carbon emissions.

Sarens crew and equipment—most notably Big Carl, the massive SGC-250 crane—have been on the Hinkley Point C project site for the last few years. For this operation, the Sarens SGC-250 and SarSpin were prepared for the challenge of installing a liner ring for Nuclear Unit 2 weighing 382T in November 2021 and another347T liner ring for Nuclear Unit 1 this month. 

Sarens dedicated a considerable amount of time to planning and coordinating the lifts with different companies and departments, and complex configurations of rigging tackle and equipment were supplied by Sarens, Tissot, and Bylor. 

The first lift was to remove the roof of the bunker within which the liner ring had been assembled, and place the roof in its temporary storage location at ground level. 

Sarens SarSpin was then picked up by the SGC- 250 and connected to Tissot’s 74T Novum Beam, a tubular steel structure designed to make the connection between Sarspin and the multiple lifting points on the liner ring. SarSpin is a self-contained, powered hydraulic leveling device suspended below the SGC-250 hookblock, operated by wireless remote control from the ground, giving the lifting team the ability to control the loadings at the lifting points during the initial pick up, to adjust the level of the suspended load and to align it with its supports during final installation. 

With the Novum Beam suspended below the Sarspin the SGC-250 travelled from the Central lifting position to the West lifting position, before slewing over the bunker and connecting to the 382T liner ring. The ring was lifted out of the bunker at a radius of 133,5 metres and installed onto the nuclear unit at a radius of 109,5 metres. 

In total, the load carried by the SGC-250 was 578,8T. It was configured with a 118-metre main boom, 52,3-metre jib, and 5.200T counterweight. 

The responsibilities for this particular lift were split into four main areas:

Tissot prepared the loads for lifting. 
Sarens, Tissot, and Bylor oversaw slinging the loads for lifting. Sarens was in charge of slinging the SarSpin, and Tissot and Bylor were responsible for slinging the Novum Beam to the SarSpin as well as to the liner ring. 
Sarens then oversaw the lifting of the load. 
Finally, Tissot and Sarens positioned the load while it was still on the crane.
Sarens was pleased to complete the operation successfully in partnership with Tissot, Bylor, and NNB. Despite on-site congestion and weather challenges, the operation proceeded smoothly, safely, and securely. 

The team was able to coordinate with the numerous other tower cranes in the area to provide a clear space for the lift and to avoid potential collisions. Additionally, the crew carefully monitored weather forecasts to execute the bunker roof and liner ring lifting operations when wind speeds were lower than 8m/second, and tackle connection and pickup to when wind speeds were lower than 14m/second.

Sarens would like to thank our project collaborators and the eight Sarens crewmembers who executed this operation, including crane operators, slingers, supervisor, AP, engineer, and management.
